143 AM EDT Sun Mar 17 2024 (Rest of today through Sunday) The area remains under the influence of a high-pressure ridge, limiting rain chances through the short term period. Mid- level ridging will begin to weaken on Sunday, but overall dry and warm conditions will continue.
Overnight lows tonight will be in the mid 60s and in the low 60s tomorrow night accompanied by mostly cloudy skies.
The upper level low in the western United States will creep eastward and become centered over Arizona today maintaining the rex blocking pattern. Areas in the far southeast Texas Panhandle and the northern Rolling Plains have the lowest chance of rain today and tonight and could remain dry and just cloudy all day. Sub-freezing temperatures are possible in the far southwest Texas Panhandle and northern South Plains tonight.
- Warmer for Monday, with increasing winds out of the west in the afternoon.
A cold front will approach the northern nature coast late tonight with a band of showers and isolated thunderstorms ahead of the front moving over the region. The cold front will push slowly south on Monday across the remainder of the forecast area.
Cold air will remain in place today and be reinforced by yet another cold front that will move through the area associated with a stronger Midwest trough this afternoon.
The forecast is still on track to see high temperatures in the mid to upper 80s, dewpoints in the low to mid 70s, and gentle southeast to south breezes through the afternoon and evening. High pressure over the western Atlantic will maintain gentle southeast to south breezes across the Keys coastal waters today and tonight. Breezes will veer to the west on Monday, ahead of a cold front that will move through the Keys waters Monday night.
Monday's highs will be several degrees warmer though still below normal for this time of year.
We're primarily looking at dry conditions across the area overnight through Monday, with the lone exception being the potential for some isolated showers along the Rio Grande as the front gets caught up across the higher terrain of Mexico and the closed low at 500mb lingers across the Desert Southwest. Outside of this low chance for showers, a cool day is expected for Monday with highs only in the 60s.
234 AM PDT Sun Mar 17 2024 Mostly dry conditions and warmer temperatures are in the forecast for the region through the middle of the week.
This light rain is occurring ahead of a cold front that continues to move southward across the OH Valley westward into the Midwest states. The cooler air in the wake of the front though looks to be displaced 12-24hr, resulting in highs later today climbing mainly into the lower 60s for most spots.
High pressure remains in place over the region through early this week, bringing above normal temperatures and continued dry conditions. Wetter and cooler weather returns over the latter half of the week and weekend.
By mid- day we're looking at mainly 20-30 PoPs and decreasing through the afternoon after the cold front pushes through the region. Despite the mid-day frontal passage today, it'll take until tomorrow before we really see a decrease in moisture through the area when reinforcing ridging pushes down from the north. As that reinforcing ridge comes in tomorrow, we'll see a breezy northeast wind develop and temperatures likely remaining in the 60s throughout the day.
High pressure remains stationary over the Pacific Northwest keeping conditions dry and clear. Warmer still through Monday.
- Cooler temperatures will push into the area tonight. Rain development will also be aided by another cold front moving into the area from the NW. High temperatures today are expected to range from the lower to mid 60s across the N to the mid to upper 70s across the SE. Cooler air behind the secondary cold front will push into the area tonight, with temperatures by Monday morning ranging from the mid 30s across the N to near 50 across the extreme SE. Mostly sunny skies are forecast for Monday, with high temperatures ranging from the mid 40s across the highest elevations of the N to the upper 60s across the extreme SE (5 to 13 degrees below normal).
951 AM EDT Sun Mar 17 2024 A large scale mid level trough will dig southeast across the Great Lakes and Ohio Valley into Monday. Afternoon highs will range from the lower 40s northwest to the lower 50s southeast. Embedded mid level energy will continue to allow aforementioned large scale mid level trough to pivot southeast toward our area. As the low level flow (around 850 mb) becomes more northwest and colder, some lake effect snow showers will develop downwind of Lake Michigan overnight. On Monday, the mid level trough will pivot southeast across the region. Some light accumulations could occur briefly on grassy/elevated surfaces, especially across the higher terrain of west central Ohio. Highs will range from the mid 30s north to the lower 40s south.
A stalled front in that area and a strong area of low pressure moving east along it will help to ensure this.
Strong high pressure will maintain its control across the Northern Rockies today through mid week.
613 AM CDT Sun Mar 17 2024 (Today) Cold front, currently located just south of I-44, will push south of the Red River shortly after sunrise.
704 AM EDT Sun Mar 17 2024 (Today through Monday) Persistent upper level ridging will continue to be the dominant synoptic influence, allowing for the warm and dry conditions to prevail across South Florida. Currently, the Lake Okeechobee area is forecasted to have the highest chance of experiencing shower and thunderstorm activity, though the Atlantic and Gulf coastlines may also witness isolated to scattered showers and storms during this period due to increased moisture and instability at lower levels.
Strong high pressure will maintain its control over the Northern Rockies today through mid week.
Highs today will mostly be in the low to mid 60s. This will help drive a cold front south across our CWA this afternoon and tonight. The rain and associated cloud cover will hold temperatures in the 60s today and the cooler air in the wake of the cold front will send temperatures in the 40s for morning lows. /22/ By Monday, the upper low pressure system is expected to eject northeast into the mid-Atlantic region. Behind the trough, northwesterly flow will increase across the area, allowing for drier and cooler air to infiltrate the Lower Mississippi Valley.
Look for highs in the upper 30s far east (influence from cooler Canadian air) to mid 50s central and west. JKL Northerly flow aloft over Montana into southern Canada, with a strong upper ridge over British Columbia.
705 AM EDT Sun Mar 17 2024 * Turning unseasonably cool tonight through Monday night, with subfreezing temperatures possible both nights.
314 AM PDT Sun Mar 17 2024 A lingering area of low pressure over the desert southwest will continue to provide chances for isolated showers and thunderstorms for areas away from the coast into the early part of the coming week. Drying will occur into the middle of the week with slightly warmer weather as weak high pressure builds into the region. A trough off the West Coast may impact the State later in the week.
A few showers are possible over areas mainly over north Mississippi today as a weak trough of low pressure moves across the region.
614 AM CDT Sun Mar 17 2024 - A passing cold front will bring a shot of chilly temperatures and blustery northwest winds to the region today and Monday. Near freezing or subfreezing low temperatures are likely tonight and very likely Monday night.
Mejia (Today) Cold front, currently located just south of I-44, will push south of the Red River shortly after sunrise.
as the upper low in Arizona drifts slowly east. This, along with the Southwest upper low moving back west, will allow rain chances will drop off sharply, with only isolated showers expected. It will be little cooler tonight, in the lower to mid 40s.
This will help drive a cold front south across our CWA this afternoon and tonight. The rain and associated cloud cover will hold temperatures in the 60s today and the cooler air in the wake of the cold front will send temperatures in the 40s for morning lows. /22/ By Monday, the upper low pressure system is expected to eject northeast into the mid-Atlantic region. Behind the trough, northwesterly flow will increase across the area, allowing for drier and cooler air to infiltrate the Lower Mississippi Valley.
618 AM CDT Sun Mar 17 2024 A few showers are possible over areas mainly over north Mississippi today as a weak trough of low pressure moves across the region.
It will be another warm afternoon with highs topping out in the low 80's along the coast and mid to upper 80's over the interior. Our next cold front is still on schedule to move through the area on Monday with scattered showers and storms possible during the day. High pressure will hold over the waters today with light winds less than 10 knots and and seas 2 feet or less.
428 AM MDT Sun Mar 17 2024 - Tranquil weather through the middle of the week, with warmer temperatures.
Highs will start to approach the mid 60's, but Monday morning lows could be in the lower 30's as a result of radiational cooling.
Low temperatures in the lower to middle 20s. Cold front has passed through the CWA, with cold air advection commencing.
(This evening through Monday Night) It may be hard to believe based off today's rainy / stormy aesthetic, but the weather pattern is in flux, and it's heading towards a much needed spell of drier and cooler weather. Meanwhile to our north, a 1037 MB high pressure system, centered over Alberta, is drifting southward into the northern and central plains. As this high continues its southward trek, colder and drier air will rush down the plains and into SE Texas. Much drier and cooler air will advect into the region tonight into tomorrow.
146 PM EDT Sun Mar 17 2024 A large scale mid level trough will dig southeast across the Great Lakes and Ohio Valley into Monday. Afternoon highs will range from the lower 40s northwest to the lower 50s southeast. Embedded mid level energy will continue to allow aforementioned large scale mid level trough to pivot southeast toward our area. As the low level flow (around 850 mb) becomes more northwest and colder, some lake effect snow showers will develop downwind of Lake Michigan overnight. On Monday, the mid level trough will pivot southeast across the region. Some light accumulations could occur briefly on grassy/elevated surfaces, especially across the higher terrain of west central Ohio. Highs will range from the mid 30s north to the lower 40s south.
1049 AM MDT Sun Mar 17 2024 - Tranquil weather through the middle of the week, with warmer temperatures.
A cold frontal boundary extends across the area this afternoon and is beginning to shift southeastward. Skies will be partly to mostly cloudy overnight, with lows in the low to mid 40s.
The trend continues into the afternoon over that region while the rest of South Central Texas stays relatively quiet and cooler with no precipitation. High temperatures are forecast to range from the low to mid 60s along and west of Interstate 35 and mid to upper 60s to the east of the I-35 corridor and Coastal Plains. Overnight lows ranges between the low to mid 40s across most areas of South Central Texas with low 50s to the southwest of Bexar County and Rio Grande.
* Turning unseasonably cool tonight through Monday night, with subfreezing temperatures possible both nights.
1236 PM CDT Sun Mar 17 2024 A reinforcing cold front has moved through Memphis and Jackson, TN and approaching Tunica and Oxford, MS.
1233 PM CDT Sun Mar 17 2024 - A passing cold front will bring a shot of chilly temperatures and blustery northwest winds to the region today and Monday. Near freezing or subfreezing low temperatures are likely tonight and very likely Monday night.
247 PM EDT Sun Mar 17 2024 - Lake Effect Snow Tonight Into Monday Morning - Winter Isn't Over Yet - Lake Effect Snow Tonight Into Monday Morning The ongoing scattered snow showers will continue over the next few hours as the 500mb positive vorticity advection and trough axis move through. As the trough axis passes we transition more into northerly flow along with some colder 850mb temperatures working their way over the lake.
A cold front sweeps through the area early tomorrow morning bringing breezy northwesterly winds (wind gusts to around 20 to 25 knots) and VFR conditions to the area during the mid to late morning hours. A stronger cold front sweeps across the area late tonight into Monday morning with a much cooler and drier airmass moving into the area for Monday. Highs today will range from the lower 60s across the northwest to low to mid 70s across the FL panhandle. Highs on Monday will be in the low to mid 60s.
A nice rest of the afternoon is in store with light winds and warmer temperatures when compared to the past few days. Lows for most will drop down to near or below freezing. The H500 low pressure system that provided the rain chances the last few days will slowly move back to the west on Monday and should be located near the California/Arizona state line by late in the day. The light winds and temperatures in the low 60s will make for a nice Spring-like day for the region.
1027 AM CDT Sun Mar 17 2024 A reinforcing cold front has moved through Memphis and Jackson, TN and approaching Tunica and Oxford, MS.
342 PM CDT Sun Mar 17 2024 - Widespread sub-freezing conditions expected tonight.
242 PM EDT Sun Mar 17 2024 An upper level low pressure system will bring scattered snow showers and an unseasonable cold airmass to the Ohio Valley on Monday.
355 PM CDT Sun Mar 17 2024 - Much warmer Monday and becoming windy.
A tight pressure gradient will keep breezy winds through the afternoon and high temperatures of the low 50s to low 60s will begin to fall fairly quickly by mid afternoon as a long fetch of northwesterly flow brings cold temps to the state.
Sub- freezing low temperatures are expected tonight and Monday night.
The cold front will continue to drop south through the evening and overnight hours, allowing temperatures north to drop into the upper-30s. Lows tomorrow night could drop below freezing, with a freeze watch in effect for a chunk of our NW zones.
However, some areas of fog development may occur in the low lying areas briefly overnight.
1232 PM EDT Sun Mar 17 2024 Weak cold front moves east, along the Appalachians early this morning. Cold front moves east along the Appalachians by 8 or 9 AM. This colder air, together with radiational cooling under mostly clear skies will drop tonight's temperatures into the upper 20s across the lowlands, ranging into the lower 20s across the higher elevations of our northeast mountains. An amplified, positive-tilt, upper trough will move through on Monday. Accumulations will not be likely across the lowlands outside of the western foothills, especially with a cold rain being the initial p-type.
324 PM EDT Sun Mar 17 2024 A pre-frontal trough will bring light showers overnight ahead of a stronger cold front expected to move through the area tomorrow.
Quiet weather is still in place this afternoon courtesy of the ridging pattern. An approaching cold front brings up to a 10 percent chance for showers between tonight and tomorrow across the island chain, but tomorrow night sees an increase to approximately 30 percent chance of rain as the boundary pushes through and enhances lift.
A bit a clearing has allowed for much warmer conditions near the Rio Grande where temperatures are in the 70s currently. A reinforcing shot of northeast winds and cooler air will arrive tonight helping to push better moisture into the higher terrain. This will also allow temperatures to cool a few more degrees tonight mostly into the low to mid 40s. Lift associated with an upper low to our west along with upslope surface flow in the higher terrain will keep temperatures about 10 degrees cooler along with scattered showers.
High pressure, centered just west of our CWA, will remain in full control over the next several days, supporting high confidence in dry, mostly sunny/clear, low-impact wx with light winds and high temps running 5-10 degrees above normal for mid-March. If anything about the forecast is a little off/overperforms, it will be temps which could yet nudge a couple degrees warmer than currently forecast.
(Rest of today through Monday) With dry cold frontal passage, colder and drier air is working into mid state region today from our north and will continue this trend through Monday afternoon. Lows tonight will dip several degrees below seasonal normal values with freezing conditions being met across most of our area. As impacts from Canadian high pressure system to our north continue to influence mid state's weather into Monday, highs are expected to be quite seasonably cool.
Freezing temperatures and widespread frost are the biggest headline in the forecast for the next seven days.
Some locations will hit freezing tonight, but frost formation might be a little limited, with dewpoint depressions of around ten degrees valley wide indicating available surface moisture is low. Northwest flow looks to strengthen Monday afternoon, bringing breezier winds to Tennessee and southwest Virginia, as the upper trough responsible swings fully into the region. In response, afternoon relative humidities will dip to the low 30s area wide. Some of the high resolution CAM guidance has suggested flurries/brief drizzle out of the clouds tomorrow afternoon.
This along with a large upper level ridge will send a Chinook front through the area that will elevate our temperatures a good 15-20 degrees above average.
Overnight lows tonight will approach 60 degrees and tomorrow will be around the low to mid 50s.
Rain-free and warm conditions expected today with highs topping out in the low 80's along the coast to mid to upper 80's over the interior. This area of low pressure and cold front will move eastward along the northern gulf coastline over the next 24-36 hours. The cold front pushes south and east of the area by late Monday evening allowing for high pressure to build in from the northwest.
An upper level low over Arizona will bring unsettled weather to the area through the early part of this week.
Aloft, a broad H500 trof w/ a potent lobe of vorticity asctd w/ a strong jet streak is set to dig S/Ewrd out of the Nrn Plains and Upper Midwest thru the day today. Tonight, freezing to sub-freezing temps wl be confined to portions of Nrn and N/Wrn AR, w/ readings near 28-32F. Frost potential (alongside freezing condns) wl be more lkly acrs Cntrl to Srn AR where sfc RH values and winds are expected to be more favorable. Preparations to protect outdoor agricultural interests should be completed today, particularly for Nrn AR as freezing condns are expected overnight tonight.
1048 AM PDT Sun Mar 17 2024 High pressure remains stationary over the Pacific Northwest keeping conditions dry and clear. Warmer still through Monday.
1221 PM CDT Sun Mar 17 2024 (Rest of today through Monday) With dry cold frontal passage, colder and drier air is working into mid state region today from our north and will continue this trend through Monday afternoon. Lows tonight will dip several degrees below seasonal normal values with freezing conditions being met across most of our area. As impacts from Canadian high pressure system to our north continue to influence mid state's weather into Monday, highs are expected to be quite seasonably cool.
Sfc cold front has now moved south of the I-20 Corridor and will continue pushing south of our region overnight. The cold front will continue to drop south through the evening and overnight hours, allowing temperatures north to drop into the upper-30s. Lows tomorrow night could drop below freezing, with a freeze watch in effect for a chunk of our NW zones.
Southern Oregon and northern California will remain under the influence of high pressure for the next few days.
(Tonight) At present, temperatures across the local area are generally in the lower to upper 50s and scattered mid to upper level clouds continue to stream overhead. A reinforcing surface cold front is also draped across northern Arkansas, northwest Tennessee, and up into eastern Kentucky. Hi-Res model guidance seems to be picking up on a slower trajectory, resulting in warmer temperatures similar to current forecast lows of mid to upper 30s north of the Tennessee River and upper 30s to around 40 degrees south. However, if the front is quicker, then temperatures could be cooler late tonight into early Monday morning.
An upper-level high-pressure system is firmly situated over the forecast region this evening. Baker City once again recorded the highest temperature today, reaching 72 degrees Fahrenheit.
931 PM CDT Sun Mar 17 2024 Much cooler temperatures will impact the Mid-South tonight with lows in the 30s areawide. ANS Freezing temperatures and widespread frost are the biggest headline in the forecast for the next seven days.
(This afternoon through Monday) Low pressure has developed across the northern Gulf of Mexico and is currently along the central LA coast. This low pressure will move east along a stalled frontal boundary that stretches across the far northern Gulf to the Big Bend area of Florida. Meanwhile, a cold front stretches from the DELMARVA Peninsula back through central TX. High pressure will begin to build in behind the front on Monday. The models are not progging much instability with the low moving east, but cannot rule out an isolated thunderstorm, especially near CSG. A colder airmass will settle across the CWA behind the cold front for the early part of the week. Those areas where temperatures are within one to two degrees from freezing will have to be watched as winds may stay up allowing for more mixing near the surface.
628 PM CDT Sun Mar 17 2024 - Much warmer Monday and becoming windy.
- Lake Effect Snow Tonight Into Monday Morning The ongoing scattered snow showers will continue over the next few hours as the 500mb positive vorticity advection and trough axis move through. As the trough axis passes we transition more into northerly flow along with some colder 850mb temperatures working their way over the lake.
916 PM CDT Sun Mar 17 2024 A cold front has moved through Middle TN and cold air is building in behind it. (Rest of today through Monday) With dry cold frontal passage, colder and drier air is working into mid state region today from our north and will continue this trend through Monday afternoon. Lows tonight will dip several degrees below seasonal normal values with freezing conditions being met across most of our area. As impacts from Canadian high pressure system to our north continue to influence mid state's weather into Monday, highs are expected to be quite seasonably cool.
830 PM EDT Sun Mar 17 2024 An upper level low pressure system will bring scattered snow showers and an unseasonable cold airmass to the Ohio Valley on Monday.
Cloud coverage has began to increase across the Nature Coast as upper level disturbance and associated cold front slowly approaches the Peninsula tonight and into Monday. Depending on the sped at which the boundary moves across the area on Monday will determine how long the low clouds and fog will be in place, but should dissipate or get washed out as the rain gets near each location.
1038 PM EDT Sun Mar 17 2024 An upper level low pressure system will bring scattered snow showers and an unseasonable cold airmass to the Ohio Valley on Monday.
(This evening through Monday) A Rex block remains the dominate feature aloft early this afternoon which will allow temperatures to warm into the low-to-mid 70s across the interior and upper 50s to mid 60s near the coast. Once low clouds and/or fog clears, afternoon temperatures are expected to be slightly warmer than today with mid- to-upper 70s across the interior and mid 60s to low 70s near the coast.
609 PM CDT Sun Mar 17 2024 - Widespread sub-freezing conditions expected tonight.
