128 PM CDT Thu Mar 28 2024 (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.
(This evening through Friday Night) Warmer than average weather will return to the Four State Region as Easter Weekend begins. This is due to surface ridging making its way further across the Mississippi River, boosting southerly surface winds and warm air advection in the process.
(Through tonight ) Increasing south winds under a weak upper ridge will start a warming trend with afternoon highs in the mid to upper 60s across eastern Oklahoma through northwest Arkansas. However a backed south-southeast wind tonight around 5 to 10 mph will produce a slightly cooler wind chills.
1222 PM 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.
225 PM CDT Thu Mar 28 2024 - 20-35% chance for rain and/or freezing rain tonight and Friday.
There is high confidence (70 percent) that rain will change to mixed precipitation (including freezing rain) by 00Z north of the Hi- Line, and 06Z for the rest of the area. Although there are probabilities south of HWY 2 for freezing rain accumulation, more accumulation is possible north of HWY 2.
1230 PM 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.
1206 PM 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.
A broad upper level high pressure ridge will build into the lower Mississippi River Valley this weekend, bringing mild and dry conditions to the Midsouth.
(This evening through Friday night) High pressure and ridging dominate the upper level pattern. Temperatures are forecast to be in the low 70s for highs and lows in the mid to upper 40s for much of the area.
(Tonight) Clear skies persist as current temps range from the low to mid 60s and northerly winds have become gusty, gusting up to 30mph at times. High pressure will continue to center over the Tennessee Valley overnight, resulting in dry conditions with calming winds.
1220 PM 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.
With temperatures in the lower 70s to near 80 degrees, we can call it Chamber of Commerce weather this afternoon. Lows tonight will be warmer as a result, bottoming out in the lower 50s to near 60 degrees. Tomorrow and tomorrow night will continue to be rain free as weak upper level ridging remains in control over the region.
1216 PM 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.
615 PM CDT Thu Mar 28 2024 A broad upper level high pressure ridge will build into the lower Mississippi River Valley this weekend, bringing mild and dry conditions to the Midsouth.
A cold front moved through earlier this afternoon and high pressure has begun to build in behind it, causing a tightened gradient across the region. Dew points have also plummeted, now ranging from the upper 50s to the lower 60s.
607 PM CDT Thu Mar 28 2024 (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.
Post-frontal, with high pressure building in from the northwest. Cooler and drier air advect down the peninsula with MClear skies. Below seasonal high temperatures are forecast with values ranging the low 70s (north) to upper 70s (south). Increasing N/NW winds behind the passing cold front, are currently forecast to cause river levels along the St.
828 PM EDT Thu Mar 28 2024 High pressure continues to build in from the Gulf Coast states tonight and Friday with gusty northwest winds.
605 PM CDT Thu Mar 28 2024 (Tonight) Clear skies persist as current temps range from the low to mid 60s and northerly winds have become gusty, gusting up to 30mph at times. High pressure will continue to center over the Tennessee Valley overnight, resulting in dry conditions with calming winds.
626 PM CDT Thu Mar 28 2024 (This evening through Friday night) High pressure and ridging dominate the upper level pattern. Temperatures are forecast to be in the low 70s for highs and lows in the mid to upper 40s for much of the area.
A cold front is just off the east coast, which has continued north to northeast winds over the region with gusty winds across the eastern Tennessee Valley at times due to the pressure gradient from east to west. Upper level ridging will build into the area. Much warmer this weekend.
636 PM CDT Thu Mar 28 2024 (This evening through Friday Night) Warmer than average weather will return to the Four State Region as Easter Weekend begins. This is due to surface ridging making its way further across the Mississippi River, boosting southerly surface winds and warm air advection in the process.
628 PM CDT Thu Mar 28 2024 (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.
631 PM CDT Thu Mar 28 2024 (Through tonight ) Increasing south winds under a weak upper ridge will start a warming trend with afternoon highs in the mid to upper 60s across eastern Oklahoma through northwest Arkansas. However a backed south-southeast wind tonight around 5 to 10 mph will produce a slightly cooler wind chills.
(Tonight) Another quiet night is underway across the central TN Valley, as a large dome of high pressure continues to settle eastward into the region.
648 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.
(The rest of tonight) Breezy southerly winds will ramp up tonight with gusts of 20-30 mph for most areas, locally higher along ridge tops.
We should get progressively warmer each day this week with highs back near 70 by Friday and in the middle to upper 70s over the weekend. A broad upper level high pressure ridge will build into the lower Mississippi River Valley this weekend, bringing mild and dry conditions to the Midsouth.
631 PM CDT Thu Mar 28 2024 - 20-35% chance for rain and/or freezing rain tonight and Friday.
727 PM EDT Thu Mar 28 2024 (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.
(Today through Saturday) A more northerly to northeasterly surface flow develops today behind the passage of a weak cold front. With a strong northerly component to the flow, much drier air is working its way down the Florida peninsula today as high pressure builds over the area.
Broad H500 ridging will build over the region through Saturday which will aid in warmer temperatures and occasional cloud cover streaming overhead. Sfc pressure gradient will intensify today and tomorrow as sfc ridging to the SE interacts with a developing low to the NW.
A ridge of high pressure to our west will move into the forecast area tonight, resulting in clear skies and light and variable winds. Trended toward the cooler side of guidance, especially over far north central WI, where a few inches of snow cover remain. High pressure will shift east during the day on Friday, with surface winds becoming E-SE during the afternoon. Sunshine and H8 WAA will allow temperatures to climb into the middle 40s to lower 50s, though onshore winds will keep readings cooler near Lake Michigan.
(Today through Saturday) High pressure is now centered over the area and will slowly slide to the east over the next days. With the dry airmass in place, temperatures will jump into the low to mid 70s today and mid to upper 70s on Saturday. A few locally warmer areas may remain near 50 degrees, with the cooler locations will drop to near 40.
128 AM EDT Fri Mar 29 2024 High pressure over the Gulf Coast states and low pressure over New England will provide windy weather today.
1129 PM CDT Thu Mar 28 2024 (This evening through Friday night) High pressure and ridging dominate the upper level pattern. Temperatures are forecast to be in the low 70s for highs and lows in the mid to upper 40s for much of the area.
(Today) Low amplitude ridging aloft will be in place today with a strengthening pressure gradient bringing a substantial increase in south winds by this afternoon.
329 AM CDT Fri Mar 29 2024 - Front moving through today will bring cooler temperatures north, but temperatures will remain warmer further south across north central Kansas.
220 AM CDT Fri Mar 29 2024 - Freezing sprinkles possible this morning.
1232 AM CDT Fri Mar 29 2024 (The rest of tonight) Breezy southerly winds will ramp up tonight with gusts of 20-30 mph for most areas, locally higher along ridge tops.
(Friday through Saturday) Very quiet weather is expected in the short-term, as subtle ridging slowly builds in over the next 36-hours. Outside of that, temperatures will begin to warm under the ridge, with highs today ranging in the upper-70s, and highs tomorrow sneaking into the low-80s.
1140 PM CDT Thu Mar 28 2024 (Tonight through Saturday night) A picture perfect afternoon ongoing across the region with temperatures in the lower 70s, dewpoints in the 40s and just a few fair weather cu developing across Southeast Texas. Increasing southerly winds will lift dewpoints from the lower 40s into the 50s by Friday evening and then into the 60s on Saturday with diurnal temperatures warming in conjunction with the invading tropical airmass. Some increase in cloud cover is expected both Friday and Saturday, but continued ridging aloft will prevent any precipitation development.
112 AM CDT Fri Mar 29 2024 (Tonight) Another quiet night is underway across the central TN Valley, as a large dome of high pressure continues to settle eastward into the region.
Although not easily detected on water vapor loops, there are several embedded waves rotating around a deep upper low offshore. An upper low about 130 miles west of the WA coast will pinwheel around a developing low along the backside of the main upper level trough and merge together.
1136 PM CDT Thu Mar 28 2024 (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.
Warmer temperatures are expected for Friday, with highs mostly in the 70s outside of mountain areas.
1022 PM CDT Thu Mar 28 2024 (This evening through Friday night) High pressure and ridging dominate the upper level pattern. Temperatures are forecast to be in the low 70s for highs and lows in the mid to upper 40s for much of the area.
This high will move east today providing an onshore flow to begin bringing moisture back to the area.
Mid to upper ridge continues to dominate the pattern aloft while at the surface, a high pressure continues to migrate eastward. Return flow from the departing high will continue to bring a warmer airmass and more Gulf moisture into the region today and Saturday. Persistent south to southeast winds, mostly cloudy skies will lead to warmer conditions through the weekend.
The exception could be across portions of the Hill Country and southern Edwards Plateau where the higher terrain will likely see occasionally gusty conditions through the night. Low clouds will become widespread late tonight into Saturday morning as southeasterly flow in the low-levels will continue.
330 AM EDT Fri Mar 29 2024 (Today through Saturday) High pressure and dry conditions are anticipated through the short term period.
High temperatures today will make it into the low 70s across our GA and AL counties, while FL counties peak in the mid 70s.
248 AM MDT Fri Mar 29 2024 A broad trough of low pressure will remain across the western US and Northern Rockies today, while the best dynamics, moisture, and precipitation focus across California. The broad trough will amplify into far southern California this weekend. The backside of the trough will provide enough moisture and lift to keep shower activity going within northwesterly flow.
Weak ridging has built in behind it, leading to a significant warm-up for parts of the Central Plains. Kansas smoke should not affect the area by Saturday thanks to the cold front progged to push through the area on Friday. Temps will be cooler in northeast portions of the area with lingering snow cover and the earlier arrival of the front.
616 AM EDT Fri Mar 29 2024 High pressure will move eastward along the Gulf Coast today, then off the Florida east coast tonight.
623 AM CDT Fri Mar 29 2024 - Front moving through today will bring cooler temperatures north, but temperatures will remain warmer further south across north central Kansas.
An upper level low will continue to drift southward today, decreasing shower activity over the region. High pressure will start to build through the weekend, giving way to warmer and drier conditions over the area.
The pressure gradient will decrease late tonight into early Saturday morning as a weak cold front stalls near/just west of the I-44 corridor. Cooler morning lows are expected across northwestern OK, but it will remain above average for most other locations as SSW surface flow continues, and dewpoints creep into the mid 50s.
A low pressure system is currently near the Washington and Canada border. Another area of low presure is developing farther west and will eventually swing around and south of the low while it becomes the primary low Friday. The low pressure system will then meander slowly southwards along the CA coast through Friday. As this low pressure moves southward, there will be wrap around showers Friday afternoon. As the low reaches central California Saturday, ridging will build in the area.
616 AM CDT Fri Mar 29 2024 (Today) Low amplitude ridging aloft will be in place today with a strengthening pressure gradient bringing a substantial increase in south winds by this afternoon.
641 AM CDT Fri Mar 29 2024 (Today through Saturday) Concur with the global/mesoscale NWP model runs that the upper pattern will remain quasi-zonal during the period, with an upper low entering the West Coast Saturday.
656 AM EDT Fri Mar 29 2024 (Today through Saturday) A more northerly to northeasterly surface flow develops today behind the passage of a weak cold front. With a strong northerly component to the flow, much drier air is working its way down the Florida peninsula today as high pressure builds over the area.
This rain and snow event will be followed by more widespread and impactful weather for the weekend and strong Pacific low pressure system affects the region.
A Wind Advisory is in effect along the higher terrain adjacent to the west side of the San Joaquin Valley, the San Joaquin Valley in mainly Merced and Madera Counties, and the Sierra Nevada foothills in mainly Madera and Mariposa Counties from this afternoon until this evening/early Saturday morning.
641 AM CDT Fri Mar 29 2024 (Friday through Saturday) Very quiet weather is expected in the short-term, as subtle ridging slowly builds in over the next 36-hours. Outside of that, temperatures will begin to warm under the ridge, with highs today ranging in the upper-70s, and highs tomorrow sneaking into the low-80s.
(Today through Saturday) Concur with the global/mesoscale NWP model runs that the upper pattern will remain quasi-zonal during the period, with an upper low entering the West Coast Saturday.
(Today through Saturday) High pressure and dry conditions are anticipated through the short term period.
615 AM CDT Fri Mar 29 2024 - Freezing sprinkles possible this morning.
647 AM CDT Fri Mar 29 2024 (Today through Saturday) High pressure is now centered over the area and will slowly slide to the east over the next days. With the dry airmass in place, temperatures will jump into the low to mid 70s today and mid to upper 70s on Saturday. A few locally warmer areas may remain near 50 degrees, with the cooler locations will drop to near 40.
247 PM EDT Fri Mar 29 2024 High pressure will move off the Florida east coast tonight.
237 PM MDT Fri Mar 29 2024 With yesterday's low pressure system leaving the region eastward, an inverted ridge of high pressure continues to build into the area from the northwest. But, the low-level cloud deck remains in place across all of our CWA, keeping a ceiling of 1000 to 2000 feet for most locations. Will be difficult to climb much above the freezing level today.
(Rest of today through Saturday) A gorgeous late "dry" season rest of the day remains in the forecast for South Florida as mid-level and surface ridging allow for quiet conditions to prevail. Although low-level moisture remains in the lowest portion of the boundary layer, there will not be much vertical extent to cloud cover/convection as the strong cap/inversion remains in place.
Temperatures on Saturday will be about 5 degrees warmer than today but winds will be 10-20 mph out of the southwest.
(Tonight) Issued at 121 PM CDT CDT Fri Mar 29 2024 High pressure located across the Southeast will keep dry conditions through the overnight hours.
1101 AM CDT Fri Mar 29 2024 GOES-16 Water Vapor satellite trends show a southern stream upper-level jet advecting Pacific moisture into the Southern Plains and into western sections of the Lower Mississippi Valley. Surface analysis late this morning places a 1024 mb ridge of high pressure over the Southeast United States. Winds are expected to increase this afternoon as a low-level jet moves slightly east into western sections of the Lower Mississippi Valley.
High pressure centered between AL/GA/FL along the Chattahoochee river will build further east over our area through the rest of the afternoon into this evening. As temperatures warm into the low/mid 70s inland away from the coast, highs will be more resistant to warm along the coast topping out in the mid/upper 60s due to the influence of cooler near shore waters. This evening, the high will hover over the area with clear skies through midnight and thin cirrus arriving from the west in the pre dawn hours towads sunrise as flow aloft in the mid and upper levels becomes more zonal over the region. Radiational cooling under the high will promote below normal lows in the low 40s north and west of highway 301, mid 40s over north central FL, and upper 40s to near 50 at the immediate coast.
Although winds will be weaker, breezy conditions will develop again overnight, especially in some of the higher elevations. An upper level trough will dig south along the California coast late tonight into tomorrow. Low clouds will scatter out by noon, and will give way to some filtered sunshine tomorrow afternoon, with highs in the low to mid 80s.
Thermal ridge along and south of the boundary will push temperatures into the low/mid 80s by afternoon, while low/mid 70s expected across the north.
Increasing upper level cloud cover continues to stream overhead as well, downstream of a longwave western CONUS trough.
- There is a 20% chance for minor travel impacts due to light freezing drizzle late this evening into the early morning hours Saturday. Soundings show a period of 1-3hr of deeper saturation within the -1 to -7C range on the back side of this exiting precipitation which could support light drizzle processes, but this also correlated with locations/timing of above freezing surface temperatures before sunset. Later this evening when most locations should be below freezing the depth of this layer is much shallower and in the case of the RAP it is showing a drier BL and mainly just stratus, which wouldn't support drizzle/freezing drizzle. HREF/NBM no longer show any potential for ice accretion during the overnight/early morning period Saturday, further lowering confidence in freezing drizzle impacts.
Atop the ridge, high based cirrus noted on satellite imagery over the plains is anticipated to spread eastward over the local area tonight. Highs on Saturday trend warmer with temperatures reaching the mid/upper 70s.
1233 PM CDT Fri Mar 29 2024 (Today through Saturday) Concur with the global/mesoscale NWP model runs that the upper pattern will remain quasi-zonal during the period, with an upper low entering the West Coast Saturday.
234 PM CDT Fri Mar 29 2024 Tonight and Saturday: Continued dry through the period with warmer temperatures. Satellite imagery/RAP analysis had a low amplitude upper level ridge axis over the central CONUS. This upper level ridge will dampen further as it continues shifting east through Saturday as well. Although morning lows will be a few degrees cooler than normal in the east they will be near normal elsewhere. /22/ Mid-level zonal flow across the Lower Mississippi Valley and surface ridging due to a strong high pressure over the Florida Peninsula will keep the area dry this weekend through the beginning of the work week.
1126 AM CDT Fri Mar 29 2024 - Freezing sprinkles possible this morning.
(This evening through Saturday Night) Warmer than average weather will continue across the Four State Region through the rest of Easter Weekend. This is due to surface ridging having made its way further across the Mississippi River, maintaining southerly surface winds and warm air advection in the process.
/SEC (Today through Saturday) High pressure and dry conditions are anticipated through the short term period.
- Rain will likely transition to freezing rain in eastern Rusk and Chippewa counties, leading to ice accumulations up to a tenth of an inch.
