617 PM CDT Tue Apr 23 2024 (Tonight through Wednesday night) An upper level ridge is moving into TX from the west with west- northwesterly winds aloft. Southeasterly flow has developed in the low levels bringing warmer, moister air back to the region. Temperatures are only around five degrees warmer today, but dewpoints are 15 to 20 degree higher. The upper trough will slowly move across TX during this period. The low level flow will remain from the southeast reinforcing the deep moisture. Low temperatures Wednesday morning will be around ten degrees warmer than this morning. The low level pattern will continue to be stagnant and warmer temperatures will move in Wednesday with highs in the 80s and lower 90s.
Lows tonight will range from the low 50s in the east to the upper 60s across the Delta.
830 PM EDT Tue Apr 23 2024 High pressure centered over the Southeast coast will drift southeast and offshore through tonight. A cold front and upper level disturbance will shift through the region Wednesday, with the front then settling to our south Wednesday night.
Yesterday and today mark the transition from dry and warm conditions, to showery and cooler weather with below- average high temperatures by the end of the week. A cooling trend begins on Thursday, accompanied by breezy afternoon winds as a trough moves into the region.
1155 PM CDT Tue Apr 23 2024 - Scattered showers and isolated thunderstorms will accompany a cold front on its approach today and passage tonight.
1230 AM CDT Wed Apr 24 2024 - High pressure will bring dry conditions to the region for Wednesday resulting in near-critical fire weather conditions.
205 AM EDT Wed Apr 24 2024 - Scattered Showers and Storms This Evening - Widespread Freezing Temperatures Wednesday Night - Showers and Thunderstorms Over the Weekend, Warmer The frontal zone is shifting southeastward through the Kalamazoo to Lansing region. - Scattered Showers and Storms This Evening Scattered diurnal showers and storms expected this evening underneath the cold pool and trough aloft should quickly fade toward midnight.
247 AM EDT Wed Apr 24 2024 High pressure will bring cool and dry conditions today and Thursday. Winds shift to the west behind the front which will allow cooler, drier air to work in from the northwest. Forecast highs only reach into the lower 50s north of I-70 to the middle 60s south of the Ohio River. A Freeze Watch remains in the highlighting areas where temperatures are most likely to drop below freezing. Forecast lows range from the lower to middle 30s areawide.
- Turning warmer and active by the end of the week through the upcoming weekend, with potential for rounds of showers and storms. The NBM has temperatures dropping to and just below freezing in northwest Illinois. High pressure aloft will briefly build over the forecast area Thursday, and then continue east, allowing southwest flow to develop Thursday night.
1043 PM CDT Tue Apr 23 2024 (Tonight through Wednesday night) An upper level ridge is gradually building into the region early this afternoon/evening, bringing in northwesterly winds aloft. These upper level winds will turn southwesterly once the ridge fully moves in early tomorrow afternoon. At the surface, a center of high pressure sits over the Southeast CONUS allowing for the continuation of southeasterly flow, therefore, increasing low level moisture over South Texas. By Wednesday afternoon, mostly sunny/partly cloudy conditions return with highs expected in the low 80s in the east to mid 90s out west across the Brush Country.
Expect daytime highs generally in the low 80s with overnight lows generally in the low to mid 50s. (Wednesday night through Thursday night) A trough moving through the Great Lakes will flatten our ridge out Wednesday night and Thursday and will also try to send a cold front down to our area. Highs will be in the lower to middle 80s with lows in the upper 50s to near 60.
patchy dense valley fog will continue to expand in coverage across portions of far northeast Oklahoma/northwest Arkansas through sunrise near cold front currently extending southwest into east central Oklahoma.
Incorporating the latest CONSShort guidance, trended warmer by a degree or two on lows, dropping into the lower 60s east to middle 60s west, with increasing clouds limiting cooling, only reinforced by southerly surface flow. Shower and thunderstorm chances will begin to increase north of I-20, as the region comes under the influence of a cold front moving through the Midwest.
Two low pressure systems will bring widespread rain showers and some thunderstorms. While we won't see much in the way of wind the low Rhs lend themselves to elevated fire weather concerns with an SPS out for northern MN.
229 AM EDT Wed Apr 24 2024 A cold front will drift southeast into central NC today, then shift to our south tonight.
This warming trend will continue into Wed/Thu with highs into the lower and middle 80s.
Instability and moisture will be lacking with this front meaning rain chances will be on the lower end as well as the chance for strong to severe storms. Severe weather is still expected to remain on the low end. High temperatures are expected to be in the mid 60s to lower 80s with overnight lows in the lower 50s to lower 60s.
134 AM EDT Wed Apr 24 2024 High pressure over the Southeast Coast will give way to a weak cold front moving down from the north.
This is based on radar trends near the Ohio River ahead of an approaching frontal boundary, in addition to the high-res model guidance. The higher elevations of the East Tennessee mountains will see gusts up to 30 or 35 mph late this afternoon through tomorrow morning. A weak cold front will bring increasing chances of rain late tonight through Wednesday morning. The higher elevations of the East Tennessee mountains will see gusts up to 30 or 35 mph late this afternoon through tomorrow morning when the front moves through. In the upper levels, a trough is over the Eastern U. and a ridge is over the Rockies. At the surface, a weak cold front will move through the region tomorrow morning. With afternoon sunshine, highs will get into the lower 70s for most of the Tennessee Valley tomorrow.
(Today) Broken to overcast bands of mid-level clouds continue to push into the Tennessee Valley ahead of a dry cold front.
1200 AM CDT Wed Apr 24 2024 (Tonight through Wednesday night) An upper level ridge is moving into TX from the west with west- northwesterly winds aloft. Southeasterly flow has developed in the low levels bringing warmer, moister air back to the region. Temperatures are only around five degrees warmer today, but dewpoints are 15 to 20 degree higher. The upper trough will slowly move across TX during this period. The low level flow will remain from the southeast reinforcing the deep moisture. Low temperatures Wednesday morning will be around ten degrees warmer than this morning. The low level pattern will continue to be stagnant and warmer temperatures will move in Wednesday with highs in the 80s and lower 90s.
Breezy within the higher terrain of the East Tennessee mountains through the early morning hours. Discussion: A relatively weak cold front stretches southwest to northeast from the mid Mississippi River Valley into the eastern Ohio River Valley. With cloud cover and light winds to help mix the low levels, the NBM has been performing rather poorly temperature wise.
237 AM EDT Wed Apr 24 2024 A cold front crosses our region today with scattered showers mainly across the mountains. Temperatures remain a few degrees either side of normal through the week with high pressure returning behind the front.
(Today through Thursday) Light rain this morning is currently moving through northern zones due to a Midwest trough and weak cold front to our north. Besides the wind shift today to the northwest, temps will still be on the rise, with upper ridging working its way eastward from the Plains. With ridging moving further east Thursday, the upward temp trend will continue with highs in the mid 70s yet again.
pdf High pressure will dominate the pattern today with clear to partly cloudy skies. High temperatures will be in the lower 80s inland and the lower to mid 70s at the coast. Low temperatures will be in the mid to upper 50s inland and the lower to mid 60s coastal.
102 AM EDT Wed Apr 24 2024 A mid-level trough and a cold front will bring rain to the area this evening. Drier and cooler weather will then be expected for Wednesday and Thursday.
An area of high pressure will remain in place across the southeastern US, slowly drifting eastward towards the Atlantic today, keeping conditions dry and skies mostly clear through tonight. As a result, afternoon temperatures are forecast to only reach the upper 70s along the coast and highs west of I-95 in the low to mid 80s.
301 AM EDT Wed Apr 24 2024 Showers will continue this morning with the passage of a cold front.
Lows tonight look to be a good 10-15 degrees higher than last night, ranging from the low 60s in the far north to right around 70 degrees on the Gulf.
1221 AM CDT Wed Apr 24 2024 - Many chances for showers and thunderstorms through the weekend with severe weather potential during several of them Elevated shower and thunderstorm activity has shifted east as the upper wave and associated weak cold front moved east and south respectively. Coverage of precipitation should increase Thursday into Thursday night as low levels saturate on south to southeast low level flow under a moderate elevated mixed layer as upper ridging exits. Cloud cover may be more scattered early in the day so highs in the 60s may still be reachable and NBM temps are slightly cooler than guidance means.
Early morning satellite imagery shows a split H5 trough in the NE Pacific which is expected to shift east and move onshore over the coming days as a transitory H5 high pressure ridge builds into the Gulf of Alaska. This trough will lead to increasing precipitation chances and slightly cooler temperatures over the coming days with highs in the 60s/70s today and 50s/60s for Thursday. Winds will remain light today outside of any thunderstorm outflows courtesy of 700 mb winds staying less than 20 kts with winds aloft increasing for Thursday as the H5 trough axis shifts overhead.
349 AM EDT Wed Apr 24 2024 A cold front will drift southeast into central NC today, then shift to our south tonight.
Fortunately, an upper level ridge builds across the central CONUS today and tomorrow keeping skies quiet. NW flow aloft counter balanced by warmer southerly flow below keeps temperatures near seasonal normals. As Thursday evening approaches, a substantial upper level trough digs south across the western CONUS. As this trough traverses the Rockies, it spins up a lower level leeward trough maintaining a negative tilt as it approaches the central CONUS. This synoptic configuration of the trough combined with enhanced southerly flow advects more warm air and moisture northward.
Today an upper-low slid well east of the state into the Great Lakes Region and a dirty ridge has now replaced it. Moist southwesterly flow is occurring as this ridge slides east and a large upper-low meanders off the coast of CA. Model soundings show it remaining quite dry in the low- levels, so strong downdrafts are possible (50%). The majority of the forecast area will remain dry thanks to that dry air in the low- levels. Wednesday looks to be the warmest day, with highs in the low to middle 70s east of the Continental Divide and low 60s to low 70s west of the Continental Divide. Certainly can see substantial snow amounts where p-type is snow with the moisture that will be available, so the highest elevations of mountain ranges could see a couple feet of snow.
1220 AM CDT Wed Apr 24 2024 (This afternoon through Wednesday night) Temperatures are warming up quickly this afternoon with weak ridging overhead and westerly winds at the surface. As the dryline pushes east this afternoon, a cold front will continue to push south, approaching the northern Permian Basin early this evening. Upper ridging will remain in place tomorrow so thunderstorm coverage looks to be isolated at best, if at all.
with perhaps a slight chance of a shower or two (main- ly across our northern CWA) and a general trend towards warmer more humid conditions (for the entire CWA). So, with mostly cloudy/partly sunny skies, highs today and tomorrow will run in the lower to mid 80s range.
1113 PM EDT Tue Apr 23 2024 - Scattered Showers and Storms This Evening - Widespread Freezing Temperatures Wednesday Night - Showers and Thunderstorms Over the Weekend, Warmer The frontal zone is shifting southeastward through the Kalamazoo to Lansing region. - Scattered Showers and Storms This Evening Scattered diurnal showers and storms expected this evening underneath the cold pool and trough aloft should quickly fade toward midnight.
- Precipitation chances increase Thursday afternoon with widespread rainshowers expected across the mountains with some light snow showers expected on the higher terrain Thursday night and beyond. - Cooler and unsettled conditions expected for the latter half of the forecast period. That trough lifts northeastward and passes just south of the Four Corners later in the day. Thursday will be windy in the southwest flow ahead of the trough, and any showers that develop will only exaggerate the winds. That system experiences lee side strengthening, which keeps our area in the base of the trough.
114 AM EDT Wed Apr 24 2024 High pressure remains in control of the weather pattern across South Florida tonight bringing dry conditions to the region. (Rest of today through Wednesday) High pressure over the SE US coast today will slide off into the western Atlantic on Wednesday.
Forecast lows in mid 20s near Lake of the Woods to the lower 30s in our south still seem reasonable. With the exit of the upper low as this ridging moves in we lose our pressure gradient and cold air advection from 925mb to 700mb reducing the winds with gusts dropping off before sunset tonight.
Still, CAMs show the mid-levels moistening up over the next several hours as a cold front approaches, bringing light showers mainly to areas north of I-40. (This afternoon through Thursday Night) A warmer day is in place across the mid state. This cold front will be a weak player in tonight's weather. Thus, just expecting some shower activity but pops and qpf will be on the low side. At that time, a warm front will be lifting northward through our area.
1233 AM CDT Wed Apr 24 2024 (Tonight through Wednesday night) Upper level ridging over the Rockies will shift eastward to the Central Plains through the period. Low-level southerly to southeasterly return flow will continue through the period, providing additional low level moisture and warmer temperatures. Low temperatures tonight and Wednesday night are forecast to be in the low 70s.
1155 PM CDT Tue Apr 23 2024 A cold front will begin to push across the Mid-South tonight. A weak cold front will bring a low chance of showers to the region late tonight through tomorrow morning.
Thanks to high pressure dominating, the weather remains in a warm, dry holding pattern, with each day becoming a bit warmer. High pressure over the area will persist, allowing for benign marine conditions. Relative humidity values are expected to be critically low each afternoon as a high pressure system dominates the pattern.
At the surface, high pressure centered over the southeastern CONUS early this evening will shift to just off the southeast East Coast by late Wednesday, but continue to ridge back west across our area. With this will likely be looking at increased mid-level clouds across the region on Wednesday, and possibly a sprinkle or two up along the Highway 84 corridor. A little warmer tonight with min temps primarily in the low 50s over all interior locations north of I-10, but upper 50s to lower 60s closer to and along the coast. Highs on Wednesday rebounding mainly into the lower 80s for most locations, but remaining in the upper 70s for some locations, especially along the coast.
Little to no fluctuation in temperatures, with afternoon high temperatures in the low to mid 80s, and overnight lows ranging from the 60s to 70 degrees.
Breezy conditions are expected through the weekend along with a gradual cooling trend as two low pressure systems move through the region.
WEATHER PATTERN OVERVIEW: A ridge off in the Dakotas keeps the region under southwest flow aloft today, leading to calm weather and temperatures as much as 15 to 20 degrees above average.
453 AM EDT Wed Apr 24 2024 Low pressure will cross the area today then continue into the Maritimes this evening as a cold front following the low pushes offshore.
116 AM EDT Wed Apr 24 2024 A weak backdoor cold front will bring only minor rain chances late Wednesday into Wednesday night. High pressure will build in from the north thereafter but should not bring cooler temperatures. Much warmer tonight compared to last night as well mixed boundary layer keep temperatures within a few degrees of climo, upper 40s to around 50 in most areas. At this latitude, we are expecting to see a glancing influence from this trough with small height falls and weak warm advection ahead of its associated cold front. Backdoor cold front will be sagging through the area at the start of the period.
1255 AM CDT Wed Apr 24 2024 - Another frost/freeze overnight with temperatures falling back near or below freezing outside the metro.
Slightly cooler and windy conditions today will give way to cooler and unsettled conditions for the second half of the week.
958 AM CDT Wed Apr 24 2024 Expect mostly cloudy, warm and humid conditions across South Texas today as a mid level ridge builds overhead. The onshore flow will gradually increase to moderate levels through the afternoon as low pressure deepens over the Central Rockies. It should be noticibly warmer today -vs- yesterday with temperatures warming into the mid 80s (east) to mid 90s (west). (Today through Thursday) Deterministic models predict a slowly progressive pattern over the CONUS during the period, with an upper level ridge (with N-S axis) is expected to move eastward across the central CONUS (including TX) today, while an upper level disturbance enters the west coast tonight then approaches the Four Corners region Thursday. Will retain the NBM maximum temperatures today/Thursday over the CWA, which are slightly warmer than both the HREF and SREF ensemble mean values.
Surface analysis shows a ridge axis across north Florida, extending from the western Atlantic. A sea breeze will keep coastal temperatures in the upper 70s, while areas along and west of I-95 warm into the low to mid 80s. An area of high pressure will remain in place across the southeastern US, slowly drifting eastward towards the Atlantic today, keeping conditions dry and skies mostly clear through tonight. As a result, afternoon temperatures are forecast to only reach the upper 70s along the coast and highs west of I-95 in the low to mid 80s.
- A warmer and more active weather pattern sets up for late in the week with temperatures nearing 80 degrees by the weekend.
A 500 mb ridge axis will move overhead today before shifting east of the forecast area on Thursday. This will allow for near normal temperatures to continue over the region with daytime highs today and Thursday in the upper 80s to mid 90s (cooler near/along the coast).
441 AM MDT Wed Apr 24 2024 - Scattered showers and thunderstorms are again expected today, mainly for the higher elevations of western and Central Wyoming.
Better moisture has returned, but it's still on the lower side.
626 AM CDT Wed Apr 24 2024 (Today through Thursday) Light rain this morning is currently moving through northern zones due to a Midwest trough and weak cold front to our north. Besides the wind shift today to the northwest, temps will still be on the rise, with upper ridging working its way eastward from the Plains. With ridging moving further east Thursday, the upward temp trend will continue with highs in the mid 70s yet again.
936 AM EDT Wed Apr 24 2024 High pressure will bring cool and dry conditions today and Thursday. A cold front is now located about halfway through the ILN forecast area. This cooler air aloft is leading to quite a bit of 1000ft-2000ft cloud development, and these clouds are gradually filling in from north to south. Winds shift to the west behind the front which will allow cooler, drier air to work in from the northwest. Forecast highs only reach into the lower 50s north of I-70 to the middle 60s south of the Ohio River. A Freeze Watch remains in the highlighting areas where temperatures are most likely to drop below freezing. Forecast lows range from the lower to middle 30s areawide.
541 AM EDT Wed Apr 24 2024 Showers will continue this morning with the passage of a cold front.
(Today through Thursday) Deterministic models predict a slowly progressive pattern over the CONUS during the period, with an upper level ridge (with N-S axis) is expected to move eastward across the central CONUS (including TX) today, while an upper level disturbance enters the west coast tonight then approaches the Four Corners region Thursday. Will retain the NBM maximum temperatures today/Thursday over the CWA, which are slightly warmer than both the HREF and SREF ensemble mean values.
308 AM MDT Wed Apr 24 2024 - Scattered showers and thunderstorms are again expected today, mainly for the higher elevations of western and Central Wyoming.
958 AM EDT Wed Apr 24 2024 Today will be cooler with scattered rain showers and a rumble of thunder in spots as an upper level disturbance crosses the region.
918 AM EDT Wed Apr 24 2024 Low pressure will cross the area today then continue into the Maritimes this evening as a cold front following the low pushes offshore.
(Rest of Today) A weak cold front was making progress southeast through southern middle TN into far northwest AL at this hour.
635 AM EDT Wed Apr 24 2024 A cold front will drift southeast into central NC today, then shift to our south tonight.
Thanks to high pressure dominating, the weather remains in a warm, dry holding pattern, with each day becoming a bit warmer.
603 AM CDT Wed Apr 24 2024 (Today) Broken to overcast bands of mid-level clouds continue to push into the Tennessee Valley ahead of a dry cold front.
High pressure settling across the western Atlantic is maintaining a slightly north of east wind with speeds generally 15 knots (or 17 mph) or less across the region. As the Florida Peninsula heats up this afternoon, a thermal trough will develop. This in turn will bifurcate the already weak high pressure and lead to a minor slackening of winds this afternoon, which will then recover overnight as the aforementioned trough dissipates. Gentle to moderate breezes will prevail over the next couple of days as high pressure moves from the Southeastern states offshore into the western Atlantic. This high will be subsumed into a larger high spreading into the western North Atlantic late this week and into the weekend.
639 AM CDT Wed Apr 24 2024 - Widespread frost and near to sub-freezing temperatures outside of Chicago tonight.
625 AM CDT Wed Apr 24 2024 Slightly warmer temperatures are forecast today, despite the passage of cold front this morning. This front will return north as a warm front tonight, spreading more humid air into the Midsouth that will persist through the weekend.
Highs are projected to push toward the lower 80s this afternoon, except at the coast where the sea breeze will work inland this afternoon keeping highs in the mid/upper 70s. pdf High pressure will dominate the pattern today with clear to partly cloudy skies. High temperatures will be in the lower 80s inland and the lower to mid 70s at the coast. Low temperatures will be in the mid to upper 50s inland and the lower to mid 60s coastal.
645 AM CDT Wed Apr 24 2024 (Today through Thursday) Deterministic models predict a slowly progressive pattern over the CONUS during the period, with an upper level ridge (with N-S axis) is expected to move eastward across the central CONUS (including TX) today, while an upper level disturbance enters the west coast tonight then approaches the Four Corners region Thursday. Will retain the NBM maximum temperatures today/Thursday over the CWA, which are slightly warmer than both the HREF and SREF ensemble mean values.
