1257 PM EST Sat Mar 9 2024 (Rest of today through Sunday) Models keep the Florida peninsula just south of the warm sector of the trough/low complex barreling through the SE CONUS. Thus, POPs for Sunday remain generally in the low-end scattered with a narrow band of rain migrating southward across SoFlo during the day. Temperatures on Sunday still remain generally in the mid-upper 80s, except the lake region where the aforementioned front activity should knock down temps a couple of degrees into the low 80s.
1039 AM MST Sat Mar 9 2024 - Warmer and dry this weekend.
632 PM EST Sat Mar 9 2024 (Through Sunday) A secondary line of showers and thunderstorms has developed across the Florida Panhandle into the Big Bend region; these are associated with the cold front that is currently pushing southeast. Any lingering showers should clear the southeastern Florida Big Bend by midnight as high pressure builds in across the region.
526 PM CST Sat Mar 9 2024 (This evening through Sunday Night) A chilly, March day best describes today with widespread low cloud cover and cold air advection in the wake of a strong cold front that moved through our region last night. Cloud cover has been very slow to erode from the northwest today but feel like that process should speed up as we move into the evening and overnight hours with very dry air infiltrating the low level air column. Have undercut NBM temps in a few locations given the very dry airmass in place and that means temperatures near freezing across our far northern zones.
A ridge will bring warmer and drier weather to the region for Sunday. Behind the departing wave, we will see a ridge develop.
623 PM EST Sat Mar 9 2024 A secondary cold front will drop south through the Great Lakes overnight with gusty winds and a few snow showers or flurries possible from time to time late this evening through Sunday morning before dry conditions return for the start of the workweek.
Some small changes to the near term forecast, with a broad upper level ridge building across the Intermountain West and further into the High Plains over the next couple of days.
and the lower to mid 50s right along the coast. Aloft, the passage of a broad trough across the Southern Plains will help with the return of some mid/high clouds late overnight/tomorrow.
A short wave trough over the southwestern US will move over West Texas on Sunday placing the region in a subsidence region aloft. Surface cyclogenesis will develop in eastern Colorado on Sunday afternoon with a surface pressure trough extending into eastern New Mexico.
-Bernhart MORNING DISCUSSION: Eastern Montana remains under upper-air ridge influence through the end of the weekend, resulting in additional melting of existing snowpack across northeast Montana. -Enriquez UPDATED: 0130Z FLIGHT CATEGORY: VFR DISCUSSION: Dry conditions are expected over the next few days as high pressure dominates across the region.
617 PM CST Sat Mar 9 2024 (This afternoon through Sunday Night) The cold front swept through Middle TN early this morning, and temperatures have been noticeably chillier today with readings mainly in the 40's at the time of this writing.
Warmer temperatures, gusty south winds, and limited moisture return will lead to elevated fire weather across northwest Oklahoma Sunday afternoon.
425 PM MST Sat Mar 9 2024 Aviation Section Time Updated Warm and breezy conditions are expected through the weekend, with temperatures generally rising into the low to mid 50s across the lower terrain.
(Through Sunday) A secondary line of showers and thunderstorms has developed across the Florida Panhandle into the Big Bend region; these are associated with the cold front that is currently pushing southeast. Any lingering showers should clear the southeastern Florida Big Bend by midnight as high pressure builds in across the region.
Closed upper low and surface reflection continue to make its way thru Lower Michigan late this evening. Overnight lows will fall into the low to mid 20s as weak low level CAA continues. An area of low pressure aloft is forecast to move from northwest to southeast across the region tonight and Sunday. Temperatures remain marginal this afternoon, with most locations at or above freezing. As we get into the evening temperatures will fall below freezing, and we'll lose the solar radiation we get from a March sun angle. The short term looks rather quiet once again with upper level ridging/milder air quickly returning to the region. Clear to partly cloudy skies are then expected for the remainder of the short term due to the building upper level ridge.
Looking at current water vapor imagery and model data, the high pressure ridge axis has moved just east of our area. Our area is still under weak high pressure with upper level clouds moving in from the west ahead of a wave/trough (now hitting the Washington and Oregon coasts) coming off of a larger upper level low system off the Pacific coast.
805 PM MST Sat Mar 9 2024 Warm and breezy conditions are expected through the weekend, with temperatures generally rising into the low to mid 50s across the lower terrain.
A weak cold front will push through the region this evening producing light showers in the mountains, with little to no impacts expected. Then Sunday afternoon another cold front, this time with modest amount of moisture, will move through the Northern Rockies.
628 PM EST Sat Mar 9 2024 - Snow accumulations by lakeshore overnight, colder Sunday - Dry to start the work week - Rain chances much of the mid to late work week timeframe Snow is starting to move in along the lakeshore as the vorticity maximum with the upper level trough moves in.
Widespread low stratus clouds in the wake of the trailing cold front persist across the TN Valley this evening, with a few sprinkles of rain (or very light showers) also noted across southern Middle TN and northeast AL. This should limit significant coverage of frost (and perhaps some light fog or freezing fog) to wind-sheltered locations as temps gradually fall into the 34-36F range.
Locations that fall into the lower and middle 30s will likely see some frost develop towards daybreak. Even though Central Texas will start the day off warmer than North Texas, extensive middle and high clouds associated with an approaching upper trough will keep highs in the lower and middle 60s (similar to the highs across North Texas). The return of low level warm air advection and passing middle and upper level clouds will keep lows Sunday night generally in the lower and middle 40s.
1217 AM EST Sun Mar 10 2024 A cold front will move through early this morning followed by cooler and drier high pressure through the early portion of the week. A warming trend is then expected mid week as high pressure shifts offshore. Rain chances will return late week as a cold front approaches. Highs Sunday will reach the low to mid 60s. Large dome of high pressure roughly centered over ArkLaTex moves eastward into the Southeast. Northwesterly winds stick around, keeping the area slightly on the cooler side.
(Today and tonight) Upper air analysis early this morning depicts a weak and compact midlevel low centered over southern New Mexico within a broader upper level ridge axis extending northward through the central CONUS. With an otherwise dry column and modest south-southwesterly flow establishing through most of the lower atmosphere, temperatures will warm nicely into the middle and upper 60s this afternoon with surface winds remaining pleasantly light.
1113 PM CST Sat Mar 9 2024 Surface analysis late this evening places a 1023 mb ridge of high pressure over portions of the Southern Plains and the Lower Mississippi Valley.
A cold front is slowly marching southward across the Florida Peninsula and eastern Gulf of Mexico this evening. Broad ridging remains in the area as a cold front slowly approaches from our north. Southerly light to gentle breezes will continue to veer southwest to west and gradually freshen through Sunday ahead of the weak cold front.
1045 PM MST Sat Mar 9 2024 Aviation Section Update Warm and breezy conditions are expected through the weekend, with temperatures generally rising into the low to mid 50s across the lower terrain.
(Today and tonight) After a cool start this morning, warmer temperatures and quiet weather is expected through the next 24 hours. This will allow surface winds to turn back out of the south at 5 to 10 mph by late morning, and temperatures to be 5 to 10 degrees warmer, with most areas getting into the low to mid 60s. Tonight, with slightly increased moisture, and southerly winds of around 5 knots in most place, overnight lows will also be warmer, by 10 to 15 degrees, with lows ranging from the upper 30s to mid 40s.
852 PM CST Sat Mar 9 2024 Surface analysis late this evening places a 1023 mb ridge of high pressure over portions of the Southern Plains and the Lower Mississippi Valley.
430 AM EDT Sun Mar 10 2024 A reinforcing cold front will move across eastern NC and offshore this morning.
1054 PM CST Sat Mar 9 2024 (This afternoon through Sunday Night) The cold front swept through Middle TN early this morning, and temperatures have been noticeably chillier today with readings mainly in the 40's at the time of this writing.
Dry conditions and warmer temperatures are expected through the middle of the week. High pressure will bring drier conditions and a strong warming trend through the first half of the week.
Amplified mid/upper level ridging is moving over the Northern Plains, with the central axis just to our west this morning.
Mid evening surface analysis had a 1023mb high centered over the southern Plains that is progged to slide east and bring a cooler and drier airmass into our CWA. This will lead to cooler than normal morning lows Sunday in the upper 30s to lower 40s.
1041 PM CST Sat Mar 9 2024 (The rest of tonight) Radiational cooling will be in full effect tonight as high pressure settles into the region. The current forecast remains on track with temperatures falling near or below freezing after midnight tonight.
1230 AM EST Sun Mar 10 2024 - Snow accumulations by lakeshore overnight, colder Sunday - Dry to start the work week - Rain chances much of the mid to late work week timeframe Snow is starting to move in along the lakeshore as the vorticity maximum with the upper level trough moves in.
(Today) A cold front that moved across the area during Saturday was nearing the East Coast. Under sunny skies temperatures should only rise into the low/mid 50s, with a steady NW wind of 5-15 mph.
(The rest of tonight) Radiational cooling will be in full effect tonight as high pressure settles into the region. The current forecast remains on track with temperatures falling near or below freezing after midnight tonight.
The gusty winds have already subsided this evening, but are expected to increase once again on Sunday as the next Pacific trough approaches from the west. Temperatures will be several degrees warmer than today, with highs near to slightly above normal.
Broad ridging remains in place across the Keys for the time being but this will change through the morning as a cold front draped across central Florida and into the Gulf of Mexico continues pressing southeastward today. The aforementioned cold front will continue to press southeastward today passing over the Island Chain during the early to mid afternoon hours. Drier air continues to infiltrate the Keys tonight in the lower levels resulting in a dry forecast.
318 AM EDT Sun Mar 10 2024 A cold front will move through early this morning followed by cooler and drier high pressure through the early portion of the week. A warming trend is then expected mid week as high pressure shifts offshore. Rain chances will return late week as a cold front approaches. Today: A cold front bisecting the forecast area across SE NC and NE SC will continue slowly passing offshore early this AM to be followed by high pressure slowly increasing from the west. The pressure gradient will remain rather strong across the area as low pressure to the northeast strengthens as well. In fact, some inland spots could reach freezing, especially in SC near and west of Bennettsville which will be closer to the high and thus have lighter winds.
1259 AM EST Sun Mar 10 2024 (06Z TAFS) Broken line of showers nearing the Tampa Bay area terminals continues moving east ahead of approaching cold front, with TEMPO SHRA group for TPA/PIE/SPG over the next few hours with MVFR/IFR cigs/vsbys with passage.
A cold front pushing across the peninsula this morning will maintain a chance of showers early over central and southern locations through the morning before exiting late morning into early afternoon. Cloudiness likely to persist south of I-4 into the afternoon followed by some improvement, with northerly winds across the area keeping temps from rising too much, although highs will likely reach the low 70s north and mid to upper 70s central and south. High pressure slowly moves across the central and eastern U.
An area of high pressure will build today, leading to warmer temperatures and drier conditions. A ridge will continue to build over Arizona today and through the first half of tomorrow.
653 AM EDT Sun Mar 10 2024 A reinforcing cold front will move across eastern NC and offshore this morning.
For the 24-hour period Sunday night through Monday night, current forecast snow totals are 2 to 6 inches in the Sawtooths with localized higher amounts along the highest peaks and 2 to 4 inches for the Centennials and Big Holes. Warmer temperatures will keep snow levels above 4,500 much of Monday, supporting rain or a rain/snow mix across the lower Snake Plain and along the I-15 corridor, as well as the eastern Magic Valley.
604 AM CDT Sun Mar 10 2024 (Today through Monday afternoon) Another chilly early morning is underway across Southeast New Mexico and West Texas, with lows expected to drop into the lower to middle 30s for most of the area, with 40s along the Rio Grande. Surface flow has already returned to the south, marking the end of our brief shot of cooler weather, and the beginning of a warming trend that will carry into midweek. Highs today are progged to top out in the lower to middle 60s for most, and upper 50s in the mountains, around 5 to 8 degrees below normal. Highs rebound above normal into the lower to middle 70s, with the return of some 80s along the Rio Grande Valley in the Big Bend.
632 AM EDT Sun Mar 10 2024 A cold front will move through early this morning followed by cooler and drier high pressure through the early portion of the week. A warming trend is then expected mid week as high pressure shifts offshore. Rain chances will return late week as a cold front approaches. Today: A cold front bisecting the forecast area across SE NC and NE SC will continue slowly passing offshore early this AM to be followed by high pressure slowly increasing from the west. The pressure gradient will remain rather strong across the area as low pressure to the northeast strengthens as well. In fact, some inland spots could reach freezing, especially in SC near and west of Bennettsville which will be closer to the high and thus have lighter winds.
/NEW/ Update: Temperatures are falling as expected this morning with many locations in the 30s and a few spots at or below freezing. Locations that fall into the lower and middle 30s will likely see some frost develop towards daybreak. Even though Central Texas will start the day off warmer than North Texas, extensive middle and high clouds associated with an approaching upper trough will keep highs in the lower and middle 60s (similar to the highs across North Texas). The return of low level warm air advection and passing middle and upper level clouds will keep lows Sunday night generally in the lower and middle 40s.
817 AM EDT Sun Mar 10 2024 (Today through Monday) The latest surface analysis places a cold front over Northern Florida with a warm and humid prefrontal airmass in place over SFL south of the boundary. High temperatures in the upper 80s to around 90 can be expected in the southeastern half of the area, while highs will only reach the lower 80s over the northern half of the area due to the earlier timing of the frontal passage. Cooler and drier air will filter in tonight behind the boundary with overnight lows ranging from the low to mid 50s over northern portions of the area, to the low to mid 60s near the southeast coast.
620 AM CDT Sun Mar 10 2024 (Today and tonight) Upper air analysis early this morning depicts a weak and compact midlevel low centered over southern New Mexico within a broader upper level ridge axis extending northward through the central CONUS. With an otherwise dry column and modest south-southwesterly flow establishing through most of the lower atmosphere, temperatures will warm nicely into the middle and upper 60s this afternoon with surface winds remaining pleasantly light.
318 AM MDT Sun Mar 10 2024 MORNING DISCUSSION: Welcome to Daylight Savings Time yall! The ridge axis of the upper-level trough will continue sliding east toward the Great Lakes region. By Monday, the trough that was along the West Coast moves into the Western US, but flattening out as it clears east of the Continental Divide, bringing a more zonal-like flow and plateau- ing the warm up across northeast Montana.
622 AM CDT Sun Mar 10 2024 (Today and tonight) After a cool start this morning, warmer temperatures and quiet weather is expected through the next 24 hours. This will allow surface winds to turn back out of the south at 5 to 10 mph by late morning, and temperatures to be 5 to 10 degrees warmer, with most areas getting into the low to mid 60s. Tonight, with slightly increased moisture, and southerly winds of around 5 knots in most place, overnight lows will also be warmer, by 10 to 15 degrees, with lows ranging from the upper 30s to mid 40s.
645 AM EDT Sun Mar 10 2024 A cold front currently draped across our area from coastal SE GA into north-central FL will shift southeastward and exit to the south after sunrise. Cool, dry airmass filters into the region as high pressure over TX builds northeastward into the TN river valley by Monday morning.
It still appears that some of the valley areas wl see temps fall to near the freezing mark arnd daybreak. High temps today will range fm the mid 50s to the lower 60s.
1001 AM EDT Sun Mar 10 2024 A cold front will move through early this morning followed by cooler and drier high pressure through the early portion of the week. A warming trend is then expected mid week as high pressure shifts offshore. Rain chances will return late week as a cold front approaches. Today: A cold front bisecting the forecast area across SE NC and NE SC will continue slowly passing offshore early this AM to be followed by high pressure slowly increasing from the west. The pressure gradient will remain rather strong across the area as low pressure to the northeast strengthens as well. In fact, some inland spots could reach freezing, especially in SC near and west of Bennettsville which will be closer to the high and thus have lighter winds.
621 AM CDT Sun Mar 10 2024 (Today through Monday) Cold front continues its way southeastward today associated with the strong upper closed low along the east coast.
Coverage continues to decrease each afternoon as high pressure over the Gulf Coast develops. Thunderstorms coverage will be key to exactly how hot things get, with greater coverage than expected leading to slightly cooler conditions.
Quality moisture content has persisted, characterized by dew pts in the low 60s with PWATs >1" being commonplace.
618 AM CDT Sun Jul 13 2025 -Portions of west/north Arkansas may see cooler temperatures Sun- Mon. The combination of the H500 trough axis in place across the region, remnant MCV across NE Oklahoma and deep moisture will lead to continued chances of widespread rain and thunderstorms across the state today and again Monday. Will begin to see a pattern change during the Tue-Wed timeframe as the lingering H500 trough becomes absorbed into the mean flow and SE US ridging begins to expand westward back over the state.
711 AM EDT Sun Jul 13 2025 A region of high pressure continues to sit over the state of Florida with associated weak westerly or northwesterly flow throughout the day. Looking ahead into early this week, an area of low pressure is expected to move across Florida into the northeastern Gulf, where it could potentially turn into a tropical system as it continues to move away to the west during midweek. High pressure will hold over the waters through tonight.
High pressure aloft, currently centered to the southeast of the forecast area, continues to slowly strengthen across the Lower Mississippi River Valley today as it builds northwest into the region. Highs will warm into the low and middle 90s, with afternoon heat index values approaching 105F. /19/ Sunday through Sunday night: An upper level trough over the central and southern Plains will try to shift east into our region but high pressure at the surface and aloft to our southeast will strengthen over our CWA through the day. With the lower rain chances and warmer temperatures topping out in the low to mid 90s, heat stress concerns will increase in our west along the Mississippi river especially.
535 AM MDT Sun Jul 13 2025 - Warmer with isolated showers and thunderstorms across the high country this afternoon.
543 AM EDT Sun Jul 13 2025 - Slightly cooler and less humid air is slow to arrive behind a weak cold front today, more noticeable tonight and Monday.
504 AM MDT Sun Jul 13 2025 - A hot finish to the weekend with highs in the 90s widespread in the lower elevations East of the Divide.
- Hot and humid conditions will remain across the Mid-South, with high temperatures generally in the low to mid 90s.
627 AM CDT Sun Jul 13 2025 (Today) Mid-level high pressure, currently centered over the northern Gulf, will build northward throughout the day today. High temps will remain in the low 90s today with max heat index values this afternoon reaching the upper 90s to around 100 degrees.
A surface and upper ridge are situated to the immediate east of Middle Tennessee this morning, so we'll find ourselves with a southwesterly surface flow today. Otherwise, we expect afternoon temperatures to warm into the lows 90s in many area, with heat index values reaching the low 100s.
River valley fog is beginning to show on satellite imagery while river valleys and locations that observed moderate to heavy rainfall this afteroon will have the highest chances to see some patchy dense fog. For this afternoon, upper trough will remain in place over the western Great Lakes with an 80-85kt H3 jet extending from northern Illinois into eastern Canada. There is no notable impulse rounding the base of the trough this afternoon, and RAP soundings show effective bulk shear less than 10kts as a result.
(Today and tonight) The mid-level trough is shifting east and has pushed much of the precipitation to the east of the area. With the trough axis in the vicinity, we likely will see redevelopment of showers and storms today, mainly across the east. But drier mid- level air is filtering into the area on the back side of the mid- level trough, with precipitable water values down to closer to one inch. The mid-level trough is now forecast to keep migrating east, although somewhat slowly, with rain chances decreasing from west to east today and tonight.
High pressure continues to remain in place off the California coast. Some mid-level moisture does look to try to undercut the high this afternoon, potentially allowing for some isolated showers and thunderstorms to develop.
Limited insolation within a post-frontal regime will result in another seasonably cool day with highs in the low 80s in far southeast KS while more typical highs in the low 90s could materialize in parts of central KS with some breaks in the clouds and lower dewpoint temperatures.
/EC/ Sunday through Sunday night: An upper level trough over the central and southern Plains will try to shift east into our region but high pressure at the surface and aloft to our southeast will strengthen over our CWA through the day. With the lower rain chances and warmer temperatures topping out in the low to mid 90s, heat stress concerns will increase in our west along the Mississippi river especially.
