1207 AM CDT Thu Mar 28 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.
1216 AM CDT Thu Mar 28 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.
Model guidance has been fairly consistent with rain developing in the warm sector of this low, poised to track along the US 30 corridor.
1028 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.
413 AM EDT Thu Mar 28 2024 As a weak cold front slowly crosses the region, scattered to numerous rain showers will continue over portions of eastern and southern Vermont today, and taper off tonight.
(Today through Friday) Axis of the upper longwave trough was moving across the area early this morning, with ridging over the Rockies. A new trough was coming onshore in the Pacific Northwest. At the surface, high pressure extended from Tulsa to Indianapolis. High pressure will continue to slide southeastward and be centered over North Florida Friday evening.
Clear skies and light winds tonight with bring maximum radiational cooling and we will see lows fall into the low to mid 30s.
(Today through Friday night) Latest 08Z obs to start this morning shows light and variable sfc winds across the Panhandles as we are downstream of a low amplitude H500 ridge. This aforementioned ridge will traverse east with its main axis across the central Plains later today.
A high pressure moving eastward and filling in behind the front will initially keep fresh to strong breezes as they clock around to the north and northeast overnight into Friday.
1152 PM EDT Wed Mar 27 2024 - Cooler, drier weather continues through Thursday.
(Today and tonight) Heights and thicknesses were making hefty gains overnight ahead of an upper ridge axis arriving later today. Surface winds on the back side of cool high pressure in Oklahoma will swing southwesterly later this morning and become breezy by the afternoon and remain this way overnight thanks to lee troughing to our west. Only a few high clouds spill over the ridge today and tonight, though this will have no impact on our today's mild temps.
Tonight, rather benign conditions will be seen as high pressure settles in from the northwest. Low temperatures will once again be in the lower 20s NW to upper 20s south of I 80. The degree and longevity of any cloud cover may keep temperatures slightly warmer. Thursday, there will be a mix of sunshine and some clouds as the ridge of high pressure remains over the area. Friday: Upper low in the northern Great Lakes region pushes into Quebec, allowing for a return of a zonal flow.
(Today and tonight) Heights and thicknesses were making hefty gains overnight ahead of an upper ridge axis arriving later today. Surface winds on the back side of cool high pressure in Oklahoma will swing southwesterly later this morning and become breezy by the afternoon and remain this way overnight thanks to lee troughing to our west. Only a few high clouds spill over the ridge today and tonight, though this will have no impact on today's mild temps.
350 AM CDT Thu Mar 28 2024 Today and tonight: Skies clear under the influence of high pressure through the near term period. Temperatures will remain seasonably cool with highs in the upper 60s and lows in the low 40s. Things trend warmer heading into the weekend.
- A beautiful Easter weekend is expected, with unseasonably warm temperatures in the lower 80s Easter afternoon. The upper levels over western Kansas will be increasingly under a ridging pattern, bringing subsidence and mostly clear conditions Today. The 850 mb wind field picks up significantly along the gradient ahead of the developing lee trough. Winds remain in the 10-15 knots range overnight as the gusts cease after sunset, apparently allowing enough mixing for temperatures to remain relatively mild â above freezing from mid 30s west to the low/mid 40s southeast. A modifying airmass in the northern plains will be warmer as itâs driven southward Friday. Warmest temperatures will likely be ahead of the surface cold front, and although itâs not that cold, itâs still the direction of the colder air.
A little less in clouds on Friday, so plenty of sun will allow temperatures to warm into the low to mid 70s.
An upper ridge will build into the central CONUS today and Friday, advecting warmer air back into the region. Friday will be even warmer, reaching the mid to upper 60s across most of the CWA, with 70s expected over southeast Nebraska and southwest Iowa.
A mesoscale precipitation band has developed west-northwest of the lowâs center as seen in regional radar imagery. The latest round of model guidance suggests this low will move across eastern Lemhi County between 400-700 AM MDT, before reaching southwest Montana thereafter. The atmosphere will destabilize this afternoon as a Pacific trough passes overhead. The primary impacts will be short lived visibility reductions, with periods of slushy roadways at the higher elevations. The Northern Rockies will remain under the influence of a broad trough under southwesterly flow keeping showers in the forecast, mainly across the higher elevations.
- Warmer temperatures persist through today and tomorrow.
(Today through Friday afternoon) A weak cold front has nudged into the area early this morning indicated with a northeasterly wind shift east of the Pecos River. A departing upper trough gives way to broad/flat ridging over the southwestern U.
1248 AM CDT Thu Mar 28 2024 - Opportunity for light precip Thursday night and Friday, generally 20-40%, with potential for freezing rain as well.
The cold airmass responsible for our recent below- normal temperatures has finally moved northeast of the region and will be replaced with an upper ridge building into the central CONUS later this week. This will advect much warmer air into the region with highs on Thursday topping out in the 60s and possibly into the low 70s by Friday.
The FA is currently between departing low pressure over the eastern FA and high pressure over the western FA. The forcing for this system continues to look pretty strong yet transient, which means there could be good snowfall rates for about a 3-6 hour period, mainly along and north of the highway 200 corridor. 925mb temperatures around 0 work up especially into areas along and south of the highway 200 corridor. Model soundings still show the potential for a little freezing rain or ice pellets, just about across the entire FA. The HREF ensemble mean precipitation type shows mainly snow, but some pockets of freezing rain.
Warmer temperatures and increasing shower and storm chances later this weekend. Clouds are dissipating quickly now, but have played a big role in keeping temps a bit cooler through the first half of the day. Ridging aloft and high pressure at the surface will move over the Ohio Valley Thursday night.
(Today and tonight) Patchy dense fog and freezing fog should dissipate quickly this morning. Lows tonight will be much warmer than previous nights--in the mid 40s to lower 50s. This marks the beginning of a rapid warmup into the weekend as the upper level ridge builds over us.
Quasi-zonal flow aloft and southeast to south flow at the surface will lead to warmer and slightly more humid conditions through the remainder of the short term period. Therefore, a dry and warmer day is on tap for southeast TX today with plenty of sunshine and highs into the low to mid 70s. Ridging aloft will continue to dominate the weather pattern on Friday. Southerly surface winds, 850 mb temperatures into the 9 to 12 degC range and mostly sunny skies will result in warmer conditions.
(Today through Friday) A dry and tranquil weather pattern is expected to continue through the short term forecast period as influences from a high pressure system remains in place. Daytime high temperatures today will be in the mid to upper 80s (cooler along/near the coast). Overnight low temperatures tonight will be in the upper 50s to mid 60s (warmer along/near the coast). Finally, highs on Friday are expected to be in the low to mid 80s (cooler along/near the coast).
High pressure is all around us with a 1024mb center in Arkadelphia. Lots of our sites calm as a result or a few still N hanging in there, but we will be NE 5 mph or light and variable this morning and then becoming S/SE 5 mph in the afternoon, in the wake of the departing high pressure area. Skies remain fair today and tonight with slightly warmer readings at this time tomorrow.
734 AM EDT Thu Mar 28 2024 (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.
(Rest of Today) High pressure will center close to the Tennessee Valley today, keeping cooler but dry conditions around. The high clouds seen earlier this morning have exited the area and we are left with sunny skies and current temps in the upper 40s/lower 50s. Despite clear skies, northerly winds will keep highs limited to the low to mid 60s this afternoon.
512 AM CDT Thu Mar 28 2024 Today and tonight: Skies clear under the influence of high pressure through the near term period. Temperatures will remain seasonably cool with highs in the upper 60s and lows in the low 40s. Things trend warmer heading into the weekend.
710 AM EDT Thu Mar 28 2024 Low pressure along the Carolina coast will track northeast and out to sea today.
624 AM CDT Thu Mar 28 2024 (Today through Friday afternoon) A weak cold front has nudged into the area early this morning indicated with a northeasterly wind shift east of the Pecos River. A departing upper trough gives way to broad/flat ridging over the southwestern U.
(Now through Friday) Northwesterly flow aloft becomes established this afternoon as a longwave trough slides over the Eastern US and into the western Atlantic. While down at the surface, a high pressure slowly slides eastward across the forecast area. High temperatures today will reach into the lower 70s for most locations with overnight lows ranging from the lower 40s inland to the upper 40s near the coast. Temperatures on Friday will be a little warmer as the high pressure becomes situated off to our east and winds turn more southeasterly to southerly. Highs are expected to rise into the lower and middle 70s.
Morning satellite imagery showed that the upper level trough axis has shifted east of Mississippi resulting in a northwest flow aloft that will continue across the region today. Despite near full insolation today, temperatures will top out cooler than normal this afternoon. /22/ Today and tonight: Skies clear under the influence of high pressure through the near term period. Temperatures will remain seasonably cool with highs in the upper 60s and lows in the low 40s. Things trend warmer heading into the weekend.
317 AM MDT Thu Mar 28 2024 MORNING DISCUSSION: A 500 hPa ridge axis this morning is moving to the east into the Dakotas. From sunset, areas of a freezing rain/snow mix increase across areas north of the Missouri River. The HREF ensemble member Skew-T plumes show that most locations have a warm enough layer from the surface to 825 hPa to sustain a freezing rain mix through mid-morning.
A weather disturbance and cold front will bring breezy conditions along with valley rain and higher elevation snow to the area today.
631 AM EDT Thu Mar 28 2024 - Cooler, drier weather continues through Thursday.
621 AM CDT Thu Mar 28 2024 (Today and tonight) Patchy dense fog and freezing fog should dissipate quickly this morning. Lows tonight will be much warmer than previous nights--in the mid 40s to lower 50s. This marks the beginning of a rapid warmup into the weekend as the upper level ridge builds over us.
528 AM CDT Thu Mar 28 2024 (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.
617 AM CDT Thu Mar 28 2024 (Today and tonight) Heights and thicknesses were making hefty gains overnight ahead of an upper ridge axis arriving later today. Surface winds on the back side of cool high pressure in Oklahoma will swing southwesterly later this morning and become breezy by the afternoon and remain this way overnight thanks to lee troughing to our west. Only a few high clouds spill over the ridge today and tonight, though this will have no impact on today's mild temps.
727 AM EDT Thu Mar 28 2024 Clouds and rain will accompany a cold front moving off the coast this morning. High pressure will bring dry and cool weather tonight through Friday. A warming trend is expected this weekend as the high moves offshore.
545 AM CDT Thu Mar 28 2024 (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.
603 AM CDT Thu Mar 28 2024 (Today through Friday) A dry and tranquil weather pattern is expected to continue through the short term forecast period as influences from a high pressure system remains in place. Daytime high temperatures today will be in the mid to upper 80s (cooler along/near the coast). Overnight low temperatures tonight will be in the upper 50s to mid 60s (warmer along/near the coast). Finally, highs on Friday are expected to be in the low to mid 80s (cooler along/near the coast).
619 AM CDT Thu Mar 28 2024 (Today through Friday) Axis of the upper longwave trough was moving across the area early this morning, with ridging over the Rockies. A new trough was coming onshore in the Pacific Northwest. At the surface, high pressure extended from Tulsa to Indianapolis. High pressure will continue to slide southeastward and be centered over North Florida Friday evening.
942 AM CDT Thu Mar 28 2024 High pressure centered over the region this morning is yielding clear skies, light winds and temperatures on their way to the lower 70s by this afternoon.
626 AM CDT Thu Mar 28 2024 - Warmer conditions prevail through the end of the week.
Windy conditions continue this evening as an earlier cold front slowly leaves the forecast area with sustained winds near 20 mph and gusts of near 30 mph. The high-level clouds associated with the front are still sitting along the island chain as well, but there has been some sunshine making it through small breaks in the clouds. Once this cold front completely clears the forecast area tonight, skies will clear up and the relatively cooler air will put overnight lows tonight in the upper 60s and afternoon highs tomorrow in the upper 70s. Afternoon highs will range from the lower to mid 80s. (18Z TAFS) A cold front pushing through the Florida Keys island chain will result in a brief bout of sub VFR CIGs at the terminals.
154 PM CDT Thu Mar 28 2024 Tonight and Friday: Continued dry through the period with cooler than normal temperatures tonight followed by near normal afternoon highs Friday. Mid afternoon satellite imagery/RAP analysis showed a mid level ridge over the central CONUS resulting in northwest flow aloft across our region. This ridge will shift east through Friday and its axis will be centered over our CWA by Friday evening. This will result in a light return flow across our CWA by Friday morning and combined with near full insolation again, temperatures will top out in the low to mid 70s. At the surface, a high pressure centered over the Florida Peninsula will continue expanding across the southeast CONUS, inhibiting convection across the region.
(This afternoon through Friday) The mid-level trough is moving east of the area, and it's a beautiful day across Central Alabama. Sunny skies will allow temperatures to warm into the mid 60s north to lower 70s south, but an 8 to 12 mph northerly breeze might make it feel a bit cooler at times, especially in the shade. Dewpoints are running on the lower side of guidance due to the dry airmass, and humidity is very low across the area. A deep layer ridge will build over the eastern CONUS tonight, and high surface pressure will center over Central Alabama. Highs will be in the lower to mid 70s with sunny skies.
1205 PM CDT Thu Mar 28 2024 (Today through Friday) Axis of the upper longwave trough was moving across the area early this morning, with ridging over the Rockies. A new trough was coming onshore in the Pacific Northwest. At the surface, high pressure extended from Tulsa to Indianapolis. High pressure will continue to slide southeastward and be centered over North Florida Friday evening.
Will be a chilly night with the high overhead with lows dipping down to a range of 39 to 43 over the interior to the mid to upper 40s closer to the coast. A nice Spring day on tap for Friday with highs lifting into the lower to mid 70s.
pdf As an upper trough passes over the region this afternoon, there is a slight chance for a shower to develop during the mid to late afternoon hours, with that chance ending in the evening as the system moves offshore. Otherwise, the cloudiness over the eastern counties will gradually decrease during the remainder of the day, with mostly clear skies expected over the forecast area Tonight, as high pressure gradually builds toward the forecast area from the west.
Weak ridging has built in behind it, leading to a significant warm-up for parts of the Central Plains.
Temperatures will be considerably warmer tonight, with lows in the low to mid 50s, with highs Friday afternoon in the upper 70s to around 80 degrees.
Later this afternoon, temperature maximums will approach the lower 70s. High pressure is all around us with a 1024mb center in Arkadelphia. Lots of our sites calm as a result or a few still N hanging in there, but we will be NE 5 mph or light and variable this morning and then becoming S/SE 5 mph in the afternoon, in the wake of the departing high pressure area. Skies remain fair today and tonight with slightly warmer readings at this time tomorrow.
Ensembles and clusters show an upper level low deepening along the West Coast through the end of the week and into the weekend.
With high pressure overhead tonight we will see clear skies and overall light winds, this will bring good radiational cooling and we should see lows fall into the mid to upper 30s east of I-65 with lower 40s west. The NBM gives areas east of I-65 a 40-60% chance of lows 36 or cooler tonight which is a good threshold for frost. We will be looking at great weather on Friday as high pressure slowly slides east.
(Rest of today through Friday) Latest surface analysis and satellite imagery places a wimpy cold front over Central Florida at present, with a very isolated line of showers currently moving across the Lake Okeechobee area.
(This evening through Friday Night) Clear/dry and warming weather will continue through the short-term as a weak/flat ridge aloft settles over the region and the onshore flow strengthens in response to lowering surface pressure over the Southern Plains. Lows tonight will be in the lower to mid 50s for most locations. And for to- morrow night, lows will be slightly warmer, in the upper 50s north to around 60s elsewhere.
250 PM CDT Thu Mar 28 2024 - Very light rain/freezing rain possible in central SD towards mid James Valley late tonight, impacts are expected to be isolated and minor.
These strong low level winds will bring much warmer 850mb air northward into the area tomorrow. This along with building mid-level ridge will result in much warmer temperatures on Friday as the west will be pushing 80 degrees.
1252 PM CDT Thu Mar 28 2024 Morning satellite imagery showed that the upper level trough axis has shifted east of Mississippi resulting in a northwest flow aloft that will continue across the region today. Despite near full insolation today, temperatures will top out cooler than normal this afternoon. /22/ Today and tonight: Skies clear under the influence of high pressure through the near term period. Temperatures will remain seasonably cool with highs in the upper 60s and lows in the low 40s. Things trend warmer heading into the weekend.
133 PM EDT Thu Mar 28 2024 - Cooler, drier weather continues through today.
317 PM EDT Thu Mar 28 2024 Low pressure along the Carolina coast will track northeast and out to sea today.
A cold front has moved through the area this morning and delivered more precipitation than forecast, with up to 0. The cold front also brought thunderstorms to southern Twin Falls County this morning.
1229 PM CDT Thu Mar 28 2024 (Today through Friday night) Latest 08Z obs to start this morning shows light and variable sfc winds across the Panhandles as we are downstream of a low amplitude H500 ridge. This aforementioned ridge will traverse east with its main axis across the central Plains later today.
1222 PM CDT Thu Mar 28 2024 (Today through Friday) A dry and tranquil weather pattern is expected to continue through the short term forecast period as influences from a high pressure system remains in place. Daytime high temperatures today will be in the mid to upper 80s (cooler along/near the coast). Overnight low temperatures tonight will be in the upper 50s to mid 60s (warmer along/near the coast). Finally, highs on Friday are expected to be in the low to mid 80s (cooler along/near the coast).
1233 PM CDT Thu Mar 28 2024 - Warmer conditions prevail through the end of the week.
Unstable conditions behind the passage of our most recent cold front has lead to convective showers, with the occasional clap of thunder mixed in where conditions are most unstable (north central ID). The large scale weather pattern will involve a low pressure system off the PacNW coast digging southward towards the California coast as it moves inland. With this southerly trajectory of the low, the bulk of the precipitation associated with it will also move southward, but that will not relieve the Northern Rockies region of all shower potential.
456 PM EDT Thu Mar 28 2024 - Temperatures will remain seasonably cool through Friday morning, with one more night of near or sub-freezing temperatures and frost returning for most valley areas late tonight. Present surface analysis has high pressure firmly established over the area. Fortunately, light winds and recent rainfall will keep fire weather concerns on the lower side. Overall, overnight lows are forecast to dip into the upper-20s in the valleys and low-30s for the ridges.
252 PM EDT Thu Mar 28 2024 Low pressure will exit offshore and to the northeast by this evening. High pressure continues to build in from the Gulf Coast states Friday with gusty northwest winds.
