Clear skies and light winds tonight with bring maximum radiational cooling and we will see lows fall into the low to mid 30s. (Thursday Night through next Wednesday) Great weather is expected as we head into the end of the week and the weekend as a strong ridge builds overhead.
1253 PM CDT Wed Mar 27 2024 - Warmer temperatures are expected through the end of the week.
138 PM EDT Wed Mar 27 2024 Late this morning a weak slow moving frontal system was located over extreme east Tennessee with a deep upper trough to the west. Today Currently early this morning, deep troughing is centered to our west with a cold front along and just west of the Cumberland Plateau ahead of high pressure. Tonight Tonight, the frontal boundary will clear the area with high pressure becoming centered just west of the Mississippi River Valley. During this time, stronger subsidence and CAA can be expected with notably cooler temperatures.
202 PM CDT Wed Mar 27 2024 - Widespread frost is expected again tonight with temperatures dropping to near freezing.
1203 PM CDT Wed Mar 27 2024 (Today and tonight) Water vapor imagery showed the base of a broad upper trough was shifting slowly across West Texas early this morning with one embedded impulse noted over the central TX Panhandle. The low is forecast to redevelop southeast into the southern Rolling Plains later this afternoon all the while the stationary front creeps to near the Highway 84 corridor while dividing milder and occasionally breezy NW winds from cooler E-NE flow. Strong height rises take hold overnight ahead of ridging for tomorrow. The stationary front meanwhile will become a cold front tonight while settling into the Permian Basin and eastern NM before ultimately washing out tomorrow morning.
(Rest of today through Thursday) A mid-level ridge over the area continues to slide eastward today as an upper level trough moves into the central US. The cold front with this incoming trough will slowly wash out as it progresses through the Florida Peninsula, evidenced by weakening theta-e advection in its approach. A bit cooler on Thursday with the anticipated frontal boundary passage so expect highs in the lower 80s across all of South Florida. Overnight lows will be quite warm, in the lower to mid 70s along the east coast of South Florida.
Active weather will begins later tonight as the next weather disturbance and cold front move into the region.
214 PM MDT Wed Mar 27 2024 - Near to above normal temperatures will continue through the weekend before the next system moves in, bringing precipitation chances and cooler temperatures.
A jet streak on the back side of exiting trough will provide sufficient forcing to aid in convective development across central Texas this afternoon. This will also mean upper level ridge building across the Plains and a return to warmer weather.
329 PM EDT Wed Mar 27 2024 - Cooler, drier weather for today and Thursday.
940 AM PDT Wed Mar 27 2024 Sunny and warm today with weak high pressure aloft.
In the wake of the mid/upper trof, skies will be clearing from the SW to the E/NE overnight. As for temperatures, tonight's lows will remain on the cooler side with mid to upper 40s for most locations. With sunny skies and light onshore winds develop- ing, highs tomorrow will be in the lower and mid 70s (upper 60s at the beaches). Lows tomorrow night will range from the lower to mid 50s across inland areas to the lower 60s at the coast.
Winds will quickly become south to southwesterly around 10-20 mph after sunrise tomorrow thanks to surface lee troughing. Southerly winds with an overhead ridge will allow highs to warm into the 70s area wide tomorrow afternoon.
1221 PM CDT Wed Mar 27 2024 (Today through Thursday afternoon) The last lingering piece of an upper trough finally moves east of the area today allowing for broad, flat ridging to build in. Abundant sunshine will help mix modest westerly winds associated with the ridge to the surface causing breezy conditions and slightly warmer temperatures. Subsidence on the back of the departing trough will stabilize the atmosphere enough so that we will not see scattered showers and virga that have occurred over the past several days. Tonight a weak cold front sags south, entering the area after sunset. In fact, temperatures Thursday will be 5 to 10 degrees warmer than today with highs easily reaching the 70s to low 80s in the Pecos River and Rio Grande valleys.
Tonight and Thursday Afternoon satellite imagery shows gradually increasing cloud cover across western Idaho as high pressure is already beginning to retreat, with another U/L trough digging into the region. As far as snowfall accumulations are concerned in the high country, not much has changed from the previous forecast with with snow totals in the 3 to 5 inch range for most with higher totals above pass level. Nevertheless, some minor blowing/drifting snow could be an issue across some of the higher terrain tomorrow with snowfall.
(Tonight through Thursday night) Pretty quiet in the short term as the mid-level trough that brought a few showers this morning exits the region allowing mid-level ridging to build in. Surface ridging will drift from over the Texas to over the southeast US over the next 24 hours and bring a more onshore flow by late in the day Thursday. The decreasing clouds, not yet onshore flow and high pressure overhead will allow for temperatures to drop into the mid 40s north and into the upper 40s and lower 50s south. Expect temperatures tomorrow to be 5-10 degreed warmerfor a lot of the area, in the upper 70s to lower 80s through the Coastal Plains and in the mid 80s west.
1217 PM CDT Wed Mar 27 2024 (The rest of today ) Temperatures have risen well above freezing as of mid-late morning, therefore the freeze warning was allowed to expire at 10 am.
A weak cold front will move through behind the trough this evening turning winds to the north at 10 mph or less. Lows will range from the upper 30s in our northwestern counties to the lower 40s for southern and eastern areas.
Issued by National Weather Service Grand Rapids MI 101 PM EDT Wed Mar 27 2024 - Cooler, drier weather for today and Thursday.
1224 PM CDT Wed Mar 27 2024 - Quiet conditions prevail today, with highs 15 to 25 degrees below normal in the lower 20s to mid 30s.
1259 PM CDT Wed Mar 27 2024 (Today through Thursday) Water vapor imagery this morning reveals a mid to upper level trough swinging across the state. At the surface, east- northeasterly winds remain in place as high pressure lingers to our northeast. With that said, the lower levels will be rather dry so we may just end up with virga. Looking at tonight, onshore flow will begin to return as high pressure moves east. Upper level ridging builds in by on Thursday as onshore flow continues at the surface. Lastly, will allow the High Risk of Rip Currents to expire at 12Z this morning.
(Tonight) High clouds will continue to spread into parts of the area from the SW this evening, as a deep upper trough axis continues to translate eastward thru the Gulf South region. Otherwise, a persistent north flow around 5-10 MPH will usher slightly cooler air into the central TN Valley overnight, with lows falling more into the upper 30s/near 40F for most spots.
138 PM EDT Wed Mar 27 2024 A few light showers could occur along the ridges from 5pm to 10pm this evening. KEY MESSAGES: - Light showers may develop along the ridges with upsloping late this evening. Deep southwesterly flow late this evening will delay the cold front progression to early tomorrow morning, near to above average temperatures through at least midnight. With cooler air filtering into the region from the west/northwest temperatures will dip below freezing for the northern/western half of the forecast area. Clouds will begin to gradually clear overnight as drier/cooler air infiltrates the region.
Some weak radar echoes were also common underneath the mid/upper level low. The greater potential for freezing temps looks to be north of Interstate 44 and will add Pawnee county to Ottawa county into another Freeze Warning for tonight from 3AM to 9AM Thursday.
1208 PM CDT Wed Mar 27 2024 (Rest of Today) Current temps have started to rebound into the lower 50s this Wed morning from their earlier lows mainly in the lower/mid 40s. Temps will continue to climb into the 60-65F range later today, as high pressure out of the Plains states begins to build into parts of the region. An upper trough pattern dropping into the western Gulf Coast will also allow for an increase in cloud cover heading into the afternoon period.
239 PM CDT Wed Mar 27 2024 High pressure is moving into the region this evening.
/29 (Thursday night through Wednesday) The broad upper trough will be moving east of our area by Thursday night.
1221 PM CDT Wed Mar 27 2024 (Today through Thursday) An upper level trough will move overhead today. A surface boundary moving west near the Rio Grande early this morning will reverse course and move back east aided by the upper level trough this afternoon.
(This afternoon through Thursday) Broad troughing is in place over the Midwest and Lower MS River Valley. The cold front is east of Central Alabama with low-level winds from the northwest transitioning to southwesterly aloft. Highs will range from the lower 60s northwest to mid 70s southeast. The mid-level portions of the trough axis will move across the area tonight. It will be cooler tomorrow as a deeper presence of northwesterly flow develops behind the trough axis with high pressure building over the region.
1119 AM EDT Wed Mar 27 2024 Late this morning a weak slow moving frontal system was located over extreme east Tennessee with a deep upper trough to the west. Today Currently early this morning, deep troughing is centered to our west with a cold front along and just west of the Cumberland Plateau ahead of high pressure. Tonight Tonight, the frontal boundary will clear the area with high pressure becoming centered just west of the Mississippi River Valley. During this time, stronger subsidence and CAA can be expected with notably cooler temperatures.
(The rest of today ) Temperatures have risen well above freezing as of mid-late morning, therefore the freeze warning was allowed to expire at 10 am.
1227 PM CDT Wed Mar 27 2024 - High pressure will deliver a fair amount of sunshine and less wind to the area today. Temperatures will remain chilly but begin to modify the rest of the week as southerly flow draws in a warmer air mass.
(This evening through Thursday Night) Relatively quiet and cooler than normal weather will continue through the next 36 hours across the Four State Region. This is due to post-frontal surface ridging that will gradually make its way south from the Great Plains, maintaining northeasterly winds.
1241 PM CDT Wed Mar 27 2024 - Seasonably cool temperatures expected today, before warmer temperatures arrive through the end of the week.
(This evening through Thursday night) High pressure and ridging dominate the upper level pattern for the short term forecast.
(This evening through Thursday) Skies were partly cloudy this afternoon behind a weak cold front that moved through the eastern Tennessee valley and southern Appalachians. Temperatures were still mild, in the lower to mid 60s behind the front with the colder air lagging behind and affecting mainly plateau counties. A deep upper low over the western Great Lakes and associated upper trough extending south through the midwest and Mississippi Valley will swing through tonight and Thursday. Low pressure off the Florida NW coast in the NE Gulf will move up the front and slow the progression of the front to the east. Thursday with upper trough passing through temperatures will be about 5 degrees cooler but with more sunshine.
AC3 Mild and dry conditions will prevail through the Easter weekend as high pressure dominates the region.
Breezes are beginning to increase as a cold front currently situated over the Gulf continues to approach the forecast area. Southeast moderate breezes tonight veer to the south and southwest tonight through tomorrow morning as a cold front approaches, and moves through, the forecast area. The cold front also brings a mix of shower and thunderstorm activity during the overnight hours tonight, and tapering off tomorrow night. A strong cold front will push through the Florida Keys on Thursday, with scattered showers and possible isolated thunderstorms expected in advance.
A low pressure system moving along the Pacific Northwest coastline tonight into Thursday morning will place western Montana and north central Idaho under southwest flow aloft. Snow levels this evening will be increasing to around 4500 to 5000 feet before crashing down to roughly 3000 to 3500 feet mid Thursday morning with the passing of a cold front. Portions of the Highway 12 corridor from Pete King Hill up to Lolo Pass and Lost Trail Pass are expected to receive 3 to 6 inches of snow, making for slick travel, particularly late tonight into mid day Thursday. We've elected to not issue advisories for these areas due to snowfall impacts being mainly isolated to the highest point on these road segments.
Pacific cold front has moved onshore in WA and OR, with a poorly defined warm front extending into se Oregon. Latest models suggest sprinkles or brief light rain this afternoon from the warm front as it moves northeast into our CWA. The main pcpn will come with the cold front, late tonight and Thursday morning.
753 PM EDT Wed Mar 27 2024 (This evening through Thursday) Skies were partly cloudy this afternoon behind a weak cold front that moved through the eastern Tennessee valley and southern Appalachians. Temperatures were still mild, in the lower to mid 60s behind the front with the colder air lagging behind and affecting mainly plateau counties. A deep upper low over the western Great Lakes and associated upper trough extending south through the midwest and Mississippi Valley will swing through tonight and Thursday. Low pressure off the Florida NW coast in the NE Gulf will move up the front and slow the progression of the front to the east. Thursday with upper trough passing through temperatures will be about 5 degrees cooler but with more sunshine.
/EC/ High pressure is moving into the region this evening.
High pressure will bring mild and dry weather before a cold and wet low pressure system arrives this weekend. A passing ridge of high pressure will bring seasonable temperatures and dry conditions to northern Arizona the next few days. Southwest winds will increase each day ahead of a deepening trough over the West Coast. This trough is associated with a potent Pacific storm and a significant push of moisture.
/33/ (This evening through Thursday Night) Relatively quiet and cooler than normal weather will continue through the next 36 hours across the Four State Region. This is due to post-frontal surface ridging that will gradually make its way south from the Great Plains, maintaining northeasterly winds.
After a cooler and slightly unsettled weekend, warm and dry weather return for the first half of the work week.
714 PM CDT Wed Mar 27 2024 - Widespread frost is expected again tonight with temperatures dropping to near freezing.
627 PM CDT Wed Mar 27 2024 (This evening through Thursday night) High pressure and ridging dominate the upper level pattern for the short term forecast.
614 PM CDT Wed Mar 27 2024 (Tonight through Thursday night) High pressure will remain in control as ridging builds in from the west. High temps on Thursday will be in the lower to mid 80s with a few low clouds. The forecasted temps will start out slightly cooler than normal but will trend to near normal after tonight, especially Thursday into Thursday night as southeast winds steady up.
A warm front will continue to bring light rain and snow to the area this evening. The bulk of the precipitation with the warm front will remain in the mountains as downsloping limits precipitation in the lower valleys. A cold front now entering southeast Oregon will move through overnight and bring widespread rain and snow. However, with temperatures near freezing, snow will have a difficult time accumulating on roadways until the cold front arrives.
657 PM EDT Wed Mar 27 2024 - Cooler, drier weather continues through Thursday.
732 PM EDT Wed Mar 27 2024 Warmer than average temperatures and periods of isolated rain showers continue through Wednesday night into Thursday morning.
518 PM CDT Wed Mar 27 2024 (Tonight) High clouds will continue to spread into parts of the area from the SW this evening, as a deep upper trough axis continues to translate eastward thru the Gulf South region. Otherwise, a persistent north flow around 5-10 MPH will usher slightly cooler air into the central TN Valley overnight, with lows falling more into the upper 30s/near 40F for most spots.
508 PM MDT Wed Mar 27 2024 - Near to above normal temperatures will continue through the weekend before the next system moves in, bringing precipitation chances and cooler temperatures.
635 PM CDT Wed Mar 27 2024 High pressure is moving into the region this evening.
713 PM CDT Wed Mar 27 2024 (Tonight through Thursday night) Pretty quiet in the short term as the mid-level trough that brought a few showers this morning exits the region allowing mid-level ridging to build in. Surface ridging will drift from over the Texas to over the southeast US over the next 24 hours and bring a more onshore flow by late in the day Thursday. The decreasing clouds, not yet onshore flow and high pressure overhead will allow for temperatures to drop into the mid 40s north and into the upper 40s and lower 50s south. Expect temperatures tomorrow to be 5-10 degreed warmer for a lot of the area, in the upper 70s to lower 80s through the Coastal Plains and in the mid 80s west.
These storms are positioned along a prefrontal trough ahead of the cold front currently draped over northern Florida. Breezes gradually increase through the morning, followed by a blast of strong northwesterly breezes in the wake of a cold frontal passage tomorrow afternoon. From synopsis, moderate southeast breezes will veer to the south and southwest through tomorrow morning as a cold front approaches, and moves through the forecast area. The cold front will also bring mix of shower and thunderstorm activity beginning late tonight, which will taper off by tomorrow afternoon.
Temperatures will be in the low to middle 30s across most of the region.
Also, north winds are persisting at 5-10 mph with a few higher gusts at times, especially the higher elevations.
638 PM CDT Wed Mar 27 2024 (This evening through Thursday Night) Relatively quiet and cooler than normal weather will continue through the next 36 hours across the Four State Region. This is due to post-frontal surface ridging that will gradually make its way south from the Great Plains, maintaining northeasterly winds.
601 PM CDT Wed Mar 27 2024 (This afternoon through Thursday) Broad troughing is in place over the Midwest and Lower MS River Valley. The cold front is east of Central Alabama with low-level winds from the northwest transitioning to southwesterly aloft. Highs will range from the lower 60s northwest to mid 70s southeast. The mid-level portions of the trough axis will move across the area tonight. It will be cooler tomorrow as a deeper presence of northwesterly flow develops behind the trough axis with high pressure building over the region.
Cooler and drier conditions are expected today with breezy northerly winds. A cold front has also moved off to our east, which has continued a northerly flow pattern when combined with the MSLP gradient. Recent CAA, height falls, and subsidence will make for a drier and cooler day today. Overall, the pattern will support a cooler night than this past night.
Next weather-maker will come from a deepening upper low in the southwestern US. With strong warm advection and lift above the warm front, could see thunderstorms Friday afternoon into Friday night especially in eastern portions of the forecast area.
It will initially begin as rain in the southwest, transitioning to freezing rain in the central, with snow in the north. - Accumulations with this system will be light, however freezing rain may lead to slippery surfaces.
1150 PM CDT Wed Mar 27 2024 - Widespread frost is expected again tonight with temperatures dropping to near freezing.
249 AM CDT Thu Mar 28 2024 - Warmer conditions prevail through the end of the week.
(Today) High clouds are finally thinning out early this morning per the latest satellite observations which should allow temperatures to drop into the lower 40s just before dawn. With high pressure nosing into the region today, clear/dry conditions will prevail.
- Low pressure system this weekend is still trending south, resulting in less snow in North Dakota.
High pressure attempts to build over the area tonight as a warm front approaches from the southwest.
(Today through Friday Night) Sfc ridging will remain in place over the area while an H500 trough shifts east of the region. Mid-level ridging will return from the west through Friday while sfc ridging shifts to the southeast.
Also, north winds are persisting at 5-10 mph with a few higher gusts at times, especially the higher elevations. (Thursday through Friday night) High pressure out of the Plains states will continue to build into much of the region for the remainder of the work week. Lingering mid/high clouds should also diminish Thu morning, as the upper trough pattern moves into the Atlantic states. A persistent NNW wind will again result in afternoon highs Thu in the lower/mid 60s.
(Today through Friday) A cold front will be moving across the region today with increasing shower and thunderstorm activity through the morning hours. Behind this convective activity is the surface front edging forward with a mid-level trough trailing it through the eastern Gulf. As the trough axis clears through later today and begins to lift north, the surface boundary will clear into the Bahamas by tonight allowing drier air to enter the region. While this is a cold front, there is little in the way of cold, continental air behind the boundary. Therefore, South Florida will cool a few degrees compared to previous days but still range from the upper 70s to the lower 80s on Friday afternoon under sunny skies.
Enough of a west wind to keep temps from dropping too fast, but as high pressure ridge moves slowly east expect to see temps drop as anticipated with single digits to lower teens. Along with snow, there is a small chance (10-20%) for freezing rain during the day on Friday as temperatures warm above freezing.
A relatively deep long wave trough remains in place through the central CONUS this afternoon with our lingering weather influences still associated with broad cyclonic flow south of the Great Lakes closed low. Although the forecast will remain dry, warm advection will increase aloft through the MO Valley as the upper trough departs spreading some mid cloudiness into the state tonight and early Thursday. The associated short wave ridging will reach the region early Friday with stronger warm advection finally returning to Iowa later in the day.
1024 PM CDT Wed Mar 27 2024 (This evening through Thursday night) High pressure and ridging dominate the upper level pattern for the short term forecast. Temperatures are forecast to be in the low 70s for highs and lows in the mid to upper 40s for much of the area.
1123 PM CDT Wed Mar 27 2024 (This evening through Thursday night) High pressure and ridging dominate the upper level pattern for the short term forecast. Temperatures are forecast to be in the low 70s for highs and lows in the mid to upper 40s for much of the area.
250 AM EDT Thu Mar 28 2024 - Cooler, drier weather continues through Thursday.
High pressure becomes centered over the region tomorrow with weak ridging aloft yielding clear skies, light northerly flow and afternoon highs in the lower 70s. The high slides east of the region Thursday night turning winds back out of the south Friday allowing dewpoints to gradually climb back into the upper 50s by Friday night.
