(Tonight through Monday night) The center of a 500 mb ridge will remain to the south of Deep South Texas and the Rio Grande Valley through Monday night. Meanwhile, on the surface, low pressure over the Sierra Madre and high pressure over the Gulf of Mexico will continue to create a tight pressure gradient over the region. This will stir up breezy to windy conditions with stronger winds expected to occur in the Lower Rio Grande Valley tomorrow. Then for tomorrow night, the low temperatures will be in the lower 70s for the entire area. The high temperatures for tomorrow are expected to be in the 90s for most of the area, but locations along the coast and on island will be in the upper 80s.
Latest soundings from nearby stations show this low-level moist layer persisting through much of the afternoon. Ridging aloft continues to build across the southern Plains, resulting in a stronger subsidence above the 900 hPa layer. Ridging aloft remains strong by Monday, though increasing moisture will keep mostly cloudy skies through most of the day. High temperatures will generally remain into the low to mid 80s.
637 PM CDT Sun Apr 14 2024 (This evening through Monday night) High pressure remains anchored near Bermuda. Southerly return flow around the high has yielded a notable increase in humidity with dewpoints around 10-15F higher than this time yesterday.
606 PM CDT Sun Apr 14 2024 (Tonight through Monday night) A low amplitude upper level ridge continues to move across TX this afternoon. A strong high pressure cell over the Gulf is generating breezy southeasterly winds across South Central Texas. The upper ridge will continue its slow trek to the east tonight and Monday. The low level flow will continue from the southeast. Low temperatures will be a couple of degrees warmer than they were this morning. The low level flow will remain from the southeast Monday. High temperatures Monday will be about the same as today ranging from the lower 80s to middle 90s. Monday evening an upper level low will move into the Great Basin bringing a trough into west TX. This will push a dryline and cold front toward our northwestern area.
A strong low pressure system will bring gusty winds and cooler temperatures this evening with isolated showers late tonight and Monday.
(This evening through Monday night) High pressure remains anchored near Bermuda. Southerly return flow around the high has yielded a notable increase in humidity with dewpoints around 10-15F higher than this time yesterday.
617 PM CDT Sun Apr 14 2024 (Tonight through Monday night) The center of a 500 mb ridge will remain to the south of Deep South Texas and the Rio Grande Valley through Monday night.

755 PM EDT Sun Apr 14 2024 Low pressure and a cold front will move through the region tonight bringing a round of showers and some thunderstorms.
Low temperatures will bottom out in the low to mid 60s. Still expecting storms to develop along the dryline during the afternoon on the back edge of the high cloud shield, with CAMs and global models favoring the TX South Plains region.
Temperatures will then trend warmer going through the middle and latter portions of this week and high pressure builds into the Desert Southwest. However, the weather pattern is transitioning as a closed low currently centered over the southern California coast will shift eastward over the next 24 hours. The only weather impact with this weather feature is continuing breezy to windy conditions today across the region, with residual breeziness continuing across southeastern Arizona tomorrow as the closed low moves east of the region.
Low temperatures will range from the low 50s northeast and far east to the mid 50s west and far south. Longwave mid-level ridging will move further east with the southern extent of the ridge axis over the Lower and Middle Mississippi River Valley. High temperatures will range from the low 80s far north and in the higher elevations east to readings in the mid 80s southwest and far south.
856 PM EDT Sun Apr 14 2024 High pressure will persist much of this week. A cold front might impact the area late in the week. The boundary layer has decoupled in a few spots this evening, but the surface pressure gradient is forecast to tighten overnight as a lee-side trough to the north sharpens a bit.
Upper level low moving to the south of Idaho tonight and southerly flow will bring moisture into the region with some showers and isolated thunderstorms in central mountains and parts of magic valley early this evening. Will turn much cooler Monday in precipitation with highs in the 40s and 50s to lower 60s in eastern Magic Valley.
1041 PM EDT Sun Apr 14 2024 Offshore high pressure brings unseasonably warm and quiet weather through at least midweek. A bit of a summer-like surface pattern in place with high pressure offshore. Meanwhile in the mid levels the highest heights will be over the western Gulf leading to a WNW flow locally. Quiet forecast period here, with offshore high pressure maintaining an influence on the area.
501 PM EDT Sun Apr 14 2024 Low pressure and a cold front will move through the region tonight bringing a round of showers and some thunderstorms.
Conditions remain mild with temperatures in the mid 70s and dew points, while higher, remain in the lower to mid 60s. Lower to mid level ridging dominate the area with sharpening ridging aloft. Expect overnight lows to range from the lower to mid 70s as some interior and protected locations will likely decouple and radiate. A ridge stretching across Florida will maintain moderate easterly breezes on Keys waters through the overnight period.
An upper low was in the process of crossing California this afternoon, while an associated jet streak was located over southern California. Modest pressure falls downstream of this trough will create some mildly breezy winds today, then an increase in winds are likely tomorrow as the trough and jet cross Arizona. NBM and MOS guidance has taken a step back in regards to winds Monday afternoon, which matches recent model trends that have sped up the timing of the trough to be exiting slightly quicker than previously forecast. For now As cooler air will push in with this trough, Monday's highs will drop into the 70s across lower elevation locations and upper 40s to 50s in higher elevations.
832 PM EDT Sun Apr 14 2024 Low pressure will track to our north tonight, and eventually drag a cold front southward across the area Monday.
659 PM EDT Sun Apr 14 2024 Low pressure and a cold front will move through the region tonight bringing a round of showers and some thunderstorms.
918 PM CDT Sun Apr 14 2024 Skies are mostly clear across the Mid-South this evening with temperatures in the low to mid 70s. Another dry and warm night is in store across the region as high pressure remains over the eastern Gulf of Mexico.
555 PM EDT Sun Apr 14 2024 High pressure will persist much of this week. A cold front might impact the area late in the week. Tonight: Bermuda high pressure will extend near and just south of the region into the Gulf of Mexico, while a subtle lee side trough prevails. In the mid and upper levels of the atmosphere we lie within the northeast periphery of low amplitude ridging, and a continued very dry west-northwest flow. It's possible that if skies clear out quickly enough across far interior Georgia, that those places could be even cooler since winds will be calm there much of the night.
Have gone ahead and issued a dense fog advisory for portions of the lower Pine Belt region given high probs for low visibility in the near term guidance, and fairly ideal conditions as previously described.
A low pressure system over northern NV continues to weaken, with the thunderstorm threat over for most of the area. As the main trough moves east into Utah, some wrap around moisture currently over central OR and the southern ID panhandle will move across the west central ID and Boise mountains on Monday morning, bringing light showers, before clearing on Monday afternoon.
800 PM EDT Sun Apr 14 2024 Offshore high pressure brings unseasonably warm and quiet weather through at least midweek. A bit of a summer-like surface pattern in place with high pressure offshore. Meanwhile in the mid levels the highest heights will be over the western Gulf leading to a WNW flow locally. Quiet forecast period here, with offshore high pressure maintaining an influence on the area.
High pressure continues to dominate through the week, keeping temperatures warm and conditions dry.
1006 PM EDT Sun Apr 14 2024 This evening, temperatures have been warmer than expected, and dew points have remained lower than expected.
636 PM CDT Sun Apr 14 2024 (Tonight through Monday night) The deterministic NWP model runs predict a progressive upper pattern, with a disturbance on the West Coast and N-S ridge over the central CONUS at the beginning of the period, and with the upper disturbance approaching the southern Plains by the end of the period.
(Today through Tuesday) Dry weather for the next two days with temperatures in the low to mid 80s today. There will be a little bit more cloud cover on Tuesday with the advancement of a system expected Tuesday night, so temperatures may be a few degrees cooler on Tuesday, but remain in the 80s across much of the area.
307 AM EDT Mon Apr 15 2024 Low pressure and a cold front will move through the region tonight bringing a round of showers and some thunderstorms.
- Expect cooler temperatures starting on Tuesday and lasting into the weekend.
Under mostly cloudy skies areawide, high temperatures are forecast to climb in the lower 80s.
(Today and tonight) A mid/upper low located just northeast of Las Vegas, NV early this morning will move northeastward over southeastern Utah this morning and then to the Colorado Front Range this afternoon.
Another warm, dry day in store for start of the work week with a mid level ridge over the Southeast today and tonight. Well above normal temps today thanks to WAA and ridge aloft, with highs nearing 90F away from the immediate coast. Backdoor cold front drops into NC tonight, though stays north of the forecast area keeping us in the warm sector with low temps around 60F. A weak cold front moves into the area Wed night, which may bring some isolated showers to the area during the overnight hours. Through Tonight: With high pressure offshore, south-southwest winds will continue to dominate the coastal waters through tonight.
(Today through Tuesday) Deep South Texas and the Rio Grande Valley will remain on the northern periphery of 500 mb high pressure centered over the Bay of Campeche during the period. In fact, highs on Tuesday will be well above normal, as the approach of a weak cold front produces a downsloping effect off of the high terrain of neighboring Mexico. Meanwhile, additionally at the surface, an enhanced pressure gradient will exist courtesy of high pressure over the Gulf of Mexico interacting with low pressure over Mexico.
(Today through Tuesday) Record highs are possible today as a strong ridge axis extending from the Gulf of Mexico to the Upper Midwest builds eastward across Tennessee. Wind speeds will be much lower today as the high pressure builds across the area. BNA climate data for today: Normal high 73 Forecast 87 Record 87 from 1936 BNA climate data for Tuesday: Normal high 73 Forecast 87 Record 88 from 1955 The warm conditions will continue tonight and Tuesday under the strong ridge.
226 AM CDT Mon Apr 15 2024 Have gone ahead and issued a dense fog advisory for portions of the lower Pine Belt region given high probs for low visibility in the near term guidance, and fairly ideal conditions as previously described.
There will be more clouds to start the day south of I80, but overall it will be a pleasantly warm start to the week with highs in the mid 60s across the northern mtns to around 80F in the Lower Susquehanna Valley. High pressure and low pwat air will bring mainly clear and cooler conditions tonight into early Tuesday morning. Another pleasantly mild day for mid April with highs in the low 60s-70s.
The WV imagery is showing a strong trough over the southwest US, with southwest flow over the Southern High Plains. To the east of the dryline southerly winds was transporting low level moisture north across much of our area with dewpoints in the lower to mid 60s. The combination of moderate instability, surface dewpoints in the lower to mid 60s and the dryline moving east will result in isolated to scattered thunderstorms developing during the late afternoon and evening, as a Pacific cold front overtakes the dryline and upper level dynamics increase.
Discussion: In the upper levels, a ridge will be over the region today and tonight. At the surface, high pressure is over the Southeast. A cold front is stalling over Kentucky and West Virginia today. Today will be warmer than normal with highs getting into the 80s for most of the Tennessee Valley which is about 10 degrees above normal. WAA will continue with southwesterly flow but winds will be much lighter than yesterday with gusts up to 15 or 20 mph likely the highest for this afternoon.
1110 PM CDT Sun Apr 14 2024 (Tonight through Tuesday night) Breezy southerly flow continues to stream low level moisture into the region this afternoon with dewpoints now consistently in the low to mid 60s area wide. Winds are expected to relax somewhat late tonight with the lightest winds expected across lower acadiana where the highest potential for fog will exist. Conditions Monday will be very similar to today with breezy southerly winds developing by late morning as the region remains sandwiched between high pressure over Florida and a developing cyclone along the Lee side of the Colorado Rockies. This low will drag a frontal boundary across Central and East Texas Tuesday keeping winds elevated and flirting with wind advisory criteria although guidance is a few knots lower this afternoon compared to yesterday.
Mid aftn temps ranged from the mid 70s to the lower 80s. The low lvl jet wl kick in once again tngt, allowing low stratus to again form later tngt into Mon mrng, with all part N AR the favored locations.
1156 PM CDT Sun Apr 14 2024 (This evening through Monday night) High pressure remains anchored near Bermuda. Southerly return flow around the high has yielded a notable increase in humidity with dewpoints around 10-15F higher than this time yesterday.
- Low pressure will generate strong storms up into western/south central SD.
138 AM EDT Mon Apr 15 2024 Offshore high pressure brings unseasonably warm and quiet weather through at least midweek. A bit of a summer-like surface pattern in place with high pressure offshore. Meanwhile in the mid levels the highest heights will be over the western Gulf leading to a WNW flow locally. Quiet forecast period here, with offshore high pressure maintaining an influence on the area. A weak backdoor cold front tries to push southward Monday night through Tuesday, but should still remain north of the area. Lows each night in the lower 60s.
1128 PM CDT Sun Apr 14 2024 Skies are mostly clear across the Mid-South this evening with temperatures in the low to mid 70s. Another dry and warm night is in store across the region as high pressure remains over the eastern Gulf of Mexico. ARS A ridge of high pressure will bring a continuation of dry weather to the Mid-South through Tuesday morning.
357 AM CDT Mon Apr 15 2024 - There is a 50% chance for areas to see greater than an inch of rainfall tonight through Tuesday night, with the highest chances across southeast North Dakota and west central Minnesota.
(Today through Tuesday) Mid-level ridging remains in place across the Gulf of Mexico and South Florida this morning, showing up nicely on the latest 00z sounding out of MFL in the form of a stout subsidence inversion. The onshore component will continue to moderate the low-level boundary layer which will allow for an increase in cloud cover at times, particularly along the east coast of South Florida. Highs later today will rise into the low 80s across the east coast metro areas with higher temperatures in the mid to upper 80s across the western half of the region.
A ridge of high pressure will keep conditions dry today. Above normal temperatures are expected to warm into the low to middle 80s.
204 AM EDT Mon Apr 15 2024 -Showers and storms tapering off just after Midnight -Continued mild with no rainfall expected Monday-Tuesday -Cooler temperature trend mid to late week with periods of rain Late evening update. High pressure and low pwat air will bring fair and dry weather for early this week. Lows will trend warmer night/night from 35-45F Monday night to 45-55F Tuesday night. A cold front moves east of the area by Monday.
A strong low pressure system will allow breezy winds and cooler temperatures to continue overnight with isolated showers late tonight and Monday.
* Showers currently moving southward through western NV as of this writing will continue to move south and end this morning as the upper low over the Great Basin exits into the Rockies and drier air works in from the north.
(Today) Mid level ridging will build in from the west throughout the day today.
With the progression of the upper trough into today, confidence is high that the cold front will clear the area by mid-morning. Ensembles aren't very bullish on a notable push of colder air in the wake of the front as an 850 mb ridge quickly builds counteracting weak cold advection in residual northwest flow; most of the day should feature a rather sunny sky with increasing subsidence drying out the boundary layer and temperatures are expected to remain above normal.
113 AM EDT Mon Apr 15 2024 This evening, temperatures have been warmer than expected, and dew points have remained lower than expected.
354 AM CDT Mon Apr 15 2024 - There is a 50% chance for areas to see greater than an inch of rainfall tonight through Tuesday night, with the highest chances across southeast North Dakota and west central Minnesota.
High pressure will remain in place over the western Atlantic, with the ridge axis extending westward over north central Florida. In the low levels, the Atlc ridge axis will initially lift north near 30N Tue and Wed then slip southward, reaching south FL Thu and there it will remain into the weekend. The low level ridge axis holds firm across south FL preventing any frontal passages and will promote a south to southwest flow turning onshore near the coast each aftn. Daily afternoon sea breezes will keep coastal communities a little cooler in the low to mid 80s Wed warming to the mid to upper 80s Fri-Sun due to a more delayed sea breeze onset.
Low temperatures will bottom out in the low to mid 60s.
Cooler today, then a warming trend through the remainder of the week. A low pressure system pushing through the region north of our area will bring cooler temperatures and gusty winds this afternoon, with strongest winds east of Tucson closer to the New Mexico border. Broad high pressure will try to build in from the west the rest of the week, however the flow will buckle a bit with the ridge losing significant amplitude as it pushes in.
The second round would be overnight as the Pacific front surges eastward under the influence of the upper low. Additionally, the low level jet will be quite strong by this point, yielding stronger low level shear and a higher (though still within the low category) risk of tornadoes with any storms that do develop.
Temperatures along the Island Chain are in the lower 70s with dew points in the upper 50s to near 60 degrees. A quiet week of weather is expected for the Florida Keys with the exception of the wind which will ebb and flow through the week due to expansive high pressure over the western North Atlantic.
(Today through Tuesday) Early morning upper air pattern showed upper ridging from south Texas to the Dakotas, with an upper low centered near Las Vegas. At the surface, high pressure extended from near Bermuda westward across much of the northern Gulf of Mexico. The axis of the upper ridge will shift to the east of the area on Tuesday, as the upper low near Las Vegas lifts northeastward to near Omaha by Tuesday evening.
1037 PM CDT Sun Apr 14 2024 (Tonight through Monday night) The deterministic NWP model runs predict a progressive upper pattern, with a disturbance on the West Coast and N-S ridge over the central CONUS at the beginning of the period, and with the upper disturbance approaching the southern Plains by the end of the period.
SW flow aloft and with the cold front remaining W/NW of AR.
With the eastward progression of the cold front overnight, along with continued (although weaker) height falls and continued increasing lower level moisture, our guard should not be let down for overnight/early Tuesday morning impactful severe weather near/east of the front.
320 AM EDT Mon Apr 15 2024 A weak cold front moves across the region today with a few showers possible.
642 AM CDT Mon Apr 15 2024 - There is a 50% chance for areas to see greater than an inch of rainfall tonight through Tuesday night, with the highest chances across southeast North Dakota and west central Minnesota.
635 AM EDT Mon Apr 15 2024 A weak cold front moves across the region today with a few showers possible.
Pleasantly warm conditions are expected with highs in the mid 60s across the northern mtns to around 80F in the Lower Susquehanna Valley. High pressure and low pwat air will bring mainly clear and cooler conditions tonight into early Tuesday morning. Another pleasantly mild day for mid April with highs in the low 60s-70s.
Low cloud cover is the predominant condition for this morning with lingering moisture after this weekend's showers, and a weak, weakening cold front making its way across northern Oregon. The low level moisture may be sufficiently deep, and lift sufficiently strong for a few drizzly showers at the Coos and Douglas coast until around 11 AM. The low clouds are expected to linger longest in the Coquille and Umpqua valleys, into this afternoon.
The 00Z KOAK sounding shows a fairly stable atmosphere in the wake of our departing low pressure system with guidance indicating weak surface winds and high RH values are expected overnight. A few locations even look to potentially peak in the lower 70's. This kicks off a warming trend as high pressure builds over the West Coast with morning lows on Tuesday expected to be in the mid to upper 40's and high temperatures in the 60's along the coast and in the 70's inland.
654 AM CDT Mon Apr 15 2024 A ridge of high pressure will keep conditions dry today. Above normal temperatures are expected to warm into the low to middle 80s.
724 AM EDT Mon Apr 15 2024 (Today through Tuesday) Mid-level ridging remains in place across the Gulf of Mexico and South Florida this morning, showing up nicely on the latest 00z sounding out of MFL in the form of a stout subsidence inversion. The onshore component will continue to moderate the low-level boundary layer which will allow for an increase in cloud cover at times, particularly along the east coast of South Florida. Highs later today will rise into the low 80s across the east coast metro areas with higher temperatures in the mid to upper 80s across the western half of the region.
A low pressure system will slide across northern Arizona today, allowing gusty winds, cooler temperatures and isolated showers. Warmer and drier weather set to return for the rest of the week. The center of a large low pressure system will slide west to east across the AZ/UT border today. This area of low pressure will quickly push eastward on Tuesday, allowing drier conditions and warmer temperatures to return.
