10:30 AM Update: Latest analysis indicates that high pressure is continuing to move toward the eastern seaboard, allowing very dry air to move into the region. Earl-morning discussion: High pressure will build into the Mid Atlantic States behind an exiting cold front. As a result, expect dry weather through the day with temperatures cooler than normal. As surface and 850 mb ridging shift offshore tonight southerly return flow will lead to moisture increases, bringing PWATs back to around an inch. What is known is that the coldest values will be over the northwestern counties with warmer values closer to the coast, possibly aided by warm air advection.
230 PM EST Thu Feb 29 2024 Lake effect snow showers will be coming to an end this evening with high pressure building in. Temperatures will turn warmer tomorrow and then a return to upper 50s to lower 60s is expected by the end of the weekend.
1026 AM MST Thu Feb 29 2024 Precipitation chances ending this morning with lowland highs in the lower sixties. Upper low centered over central New Mexico this morning will progress eastward today, taking the precip and cloud cover with it. Lowland highs look to reach the lower 60s, slightly below climate normals for the end of February. Zonal flow aloft shifting to the southwest over the upcoming weekend will keep us dry and allow us to quickly recover from yesterday's cold front. Lowland highs return to the lower 70s as early as Friday afternoon, remaining warm through the weekend.
High pressure will develop at the surface to our east, turning our winds back to the southeast by this afternoon. Then, as we go into the overnight hours lighter winds and clear skies could allow for radiational cooling and lows to drop into the low to upper 30s. Highs will be in the low to mid 80s, with overnight lows generally in the 50s.
540 PM CST Thu Feb 29 2024 (Tonight through Friday night) The overall synoptic pattern this afternoon across the country consists of a southeast Canadian mid-level low with the trough axis extending down across New England and offshore. For tonight there's low confidence of a Coastal Trough bringing some showers this evening through the overnight hours so, opted to stick with silent PoP's. Tomorrow will be warmer with highs ranging in the 70s.
454 PM EST Thu Feb 29 2024 -Mild pattern resumes Friday as March comes in like a lamb -Wet start to the first weekend of March -Temps will be well above normal for the first week of March, with the highest chance for rain Wed-Thu Drier air has worked into central PA, bringing an end to the earlier snow shower activity. High pressure moving just offshore on Friday will allow for a clear and cool start to the day, with high clouds developing as the day goes on. Fri afternoon will be much warmer than Thu, with highs in the 40s.
Temperatures are in the lower to mid 50s in the Bitterroot valley and Camas Prairie in Idaho with mid and upper 40s elsewhere. This will all come to an end late this afternoon and more so through the evening hours as a strong cold front will make its way through the NR. The large trough will remain over the region through the weekend.
The highest accumulations are anticipated over lower Acadiana with very light amounts in general across SE TX and far west LA.
654 PM EST Thu Feb 29 2024 - Return to warmer than normal temperatures this weekend.
(This afternoon through Friday) At a glance: - Cloudy, dry, and mild today - Unseasonably cool and rainy Friday Cooler, drier air has settled in across north and central Georgia in the wake of yesterday's cold front. Supported by a brief period of zonal flow aloft and high pressure at the surface, expect relatively tranquil conditions today. Highs will be in the mid-50s to lower-60s -- some 15-20 degrees cooler than yesterday -- with lows in the 40s.
624 PM EST Thu Feb 29 2024 -Mild pattern resumes Friday as March comes in like a lamb -Wet start to the first weekend of March -Temps will be well above normal for the first week of March, with the highest chance for rain Wed-Thu Drier air has worked into central PA, bringing an end to the earlier snow shower activity. High pressure moving just offshore on Friday will allow for a clear and cool start to the day, with high clouds developing as the day goes on. Fri afternoon will be much warmer than Thu, with highs in the 40s.
At this time the lowest clouds are primarily over east central and northeast Florida, but overnight the northeast to east flow will drive these lower clouds westward into our area, especially from around Tampa Bay and the Interstate 4 corridor northward. Conditions will gradually improve Friday morning with the low clouds lifting, but abundant high clouds will persist through the day keeping skies mostly cloudy.
(Tonight) Low chances (20-30%) for light rain showers will continue late this evening ahead of an upper trough shifting into the lower Mississippi Valley and Mid South region. Collectively, this will prevent temperatures from dropping off much overnight, with lows in the low to mid 40s being common.
(Tonight through Friday night) The overall synoptic pattern this afternoon across the country consists of a southeast Canadian mid-level low with the trough axis extending down across New England and offshore. For tonight there's low confidence of a Coastal Trough bringing some showers this evening through the overnight hours so, opted to stick with silent PoP's. Tomorrow will be warmer with highs ranging in the 70s.
However, with temperatures at the surface above freezing, no impacts to roadways are anticipated.
Warmer and drier conditions are expected through the end of the week. This weekend will be windy as the aforementioned trough passes through the Great Basin.
939 PM EST Thu Feb 29 2024 -Mild pattern resumes Friday as March comes in like a lamb -Wet start to the first weekend of March -Temps will be well above normal for the first week of March, with the highest chance for rain Wed-Thu Drier air has worked into central PA, bringing an end to the earlier snow shower activity.

Fri afternoon will be much warmer than Thu, with highs in the 40s.
542 PM CST Thu Feb 29 2024 (This evening through Friday) A compact but potent upper level low centered over the TX Panhandle at midday will continue to accelerate northeastward and is on track to exit our area by this evening. Despite the clearing skies and snow cover over the SW TX Panhandle, temperatures will remain only seasonably chilly as continuing south to southwest breezes prevent most locations from falling much below the lower 30s tonight. The atmosphere will dry considerably on Friday as the upper low continues to exit to our northeast and flow aloft becomes more zonal.
However, with time precipitation aloft along with gradually strengthening WAA will moisten the lower levels of the atmosphere enough for rain to reach the surface, which is most likely to occur in the 05-10Z timeframe from southwest early to northeast late. (This afternoon through Friday Night) It's a cool afternoon across the area with temperatures in the lower to mid 40s.
As often seems to be the case with ArkLaTex weather, temperatures look to put on an exhibition of all four seasons in as many days, thanks to ridging building in from the west and ushering in a pronounced warming trend. Tomorrow will resemble a pleasant Autumn afternoon, while highs climb into the 60s across the region, even approaching 70 at a few warmer sites.
927 PM EST Thu Feb 29 2024 High pressure over the region will move to the Mid Atlantic coast by Friday morning.
521 PM CST Thu Feb 29 2024 (This afternoon through Friday Night) It's a cool afternoon across the area with temperatures in the lower to mid 40s.
949 PM EST Thu Feb 29 2024 Lake effect snow showers will be coming to an end this evening with high pressure building in. Temperatures will turn warmer tomorrow and then a return to upper 50s to lower 60s is expected by the end of the weekend.
Steered towards the low end of NBM guidance based on our local wedge tool scheme and current dew points (and thus wet bulbs) are running below guidance means.
Martin (This afternoon through Friday) At a glance: - Cloudy, dry, and mild today - Unseasonably cool and rainy Friday Cooler, drier air has settled in across north and central Georgia in the wake of yesterday's cold front. Supported by a brief period of zonal flow aloft and high pressure at the surface, expect relatively tranquil conditions today. Highs will be in the mid-50s to lower-60s -- some 15-20 degrees cooler than yesterday -- with lows in the 40s.
Look for clouds to increase in the lower and mid levels with chances for showers increasing through the night from the southwest. Broad troughing will remain over the Lower Mississippi River Valley with continued impulses moving northeast over the area. Cloudy skies will persist areawide Friday with high chances for rain showers and some thunderstorms will be possible, though likely elevated in nature as surface instability values are low and convective development will be highly reliant on steepening lapse rates due to cooler air aloft.
647 PM EST Thu Feb 29 2024 Lake effect snow showers will be coming to an end this evening with high pressure building in. Temperatures will turn warmer tomorrow and then a return to upper 50s to lower 60s is expected by the end of the weekend.
642 PM EST Thu Feb 29 2024 High pressure over the region will move to the Mid Atlantic coast by Friday morning.
Light rain or drizzle could continue throughout the night reinforcing the low cloud cover, cool temps and poor visibility.
A stationary front is bisecting the area and will eventually lift north tomorrow as a warm front. Some improvements are expected to conditions after 15z Fri as a warm front lifts north of the area.
1049 PM CST Thu Feb 29 2024 (This evening through Friday) A compact but potent upper level low centered over the TX Panhandle at midday will continue to accelerate northeastward and is on track to exit our area by this evening. Despite the clearing skies and snow cover over the SW TX Panhandle, temperatures will remain only seasonably chilly as continuing south to southwest breezes prevent most locations from falling much below the lower 30s tonight. The atmosphere will dry considerably on Friday as the upper low continues to exit to our northeast and flow aloft becomes more zonal.
(Today) Satellite imagery shows a low pressure system spinning across northeast OK/southeast KS this morning. With sfc dewpoints as of 07z still in the low to mid 20s, any returns on radar early this morning will likely remain as virga until better moisture arrives by sunrise.
346 AM EST Fri Mar 1 2024 -Mild pattern resumes Friday as March comes in like a lamb -Wet start to the first weekend of March -Temps will be well above normal for the first week of March, with the highest chance for rain Wed-Thu Clear skies, light wind and dry air associated with high pressure slipping south of PA is allowing for efficient radiational cooling tonight. Based on latest observations, have lowered the min temp forecast with expected readings at dawn ranging from the low teens in the coldest northern valleys, to the mid 20s over parts of the Lower Susq Valley.
After a chilly start to the day on Friday, plenty of sunshine will help temps rise into the 40s to near 50, some 15-20 degrees warmer than Thursday.
A passing system will bring gusty winds, cooler temperatures, and chances for precipitation through the weekend. The West Coast trough that is currently driving our weather is gradually making its way east. Slight changes were made for tonight's wind forecast to reflect confidence in strong winds downslope of the high terrain.
1222 AM EST Fri Mar 1 2024 - Return to warmer than normal temperatures this weekend.
This high is generating a broad field of moderate easterly breezes. Stable conditions continue with only weak low level lift and a convection blocking inversion just above 850 mb. There are patches of stratocumulus, but they are mostly relegated to the warmer Florida Straits. Expect lows to settle in the lower 70s with dew points holding broadly near 70. Winds will be stronger over the Florida Straits due to both proximity to the ridge and mesoscale land effects.
1052 PM CST Thu Feb 29 2024 (Tonight) Low chances (20-30%) for light rain showers will continue late this evening ahead of an upper trough shifting into the lower Mississippi Valley and Mid South region. Collectively, this will prevent temperatures from dropping off much overnight, with lows in the low to mid 40s being common.
Low clouds on the the northern and western sides of the low will move east with it leaving mostly sunny and warm conditions this afternoon.
The front will extend a little further to the north Tonight, with lows ranging from the mid to upper 50s SE GA, to the lower 60s SE GA.
1257 AM EST Fri Mar 1 2024 High pressure over the region will move to the Mid Atlantic coast by this morning.
224 AM EST Fri Mar 1 2024 - Return to warmer than normal temperatures this weekend.
The existence of the cold air on our side of the mountains near the surface means an inversion aloft likely will keep the gustiest of winds confined to the higher elevations, so that's where the wind advisory shall remain.
350 AM MST Fri Mar 1 2024 Quick Synopsis: Winds diminish over the western foothills early this morning, heavy mountain snow into the weekend, unsettled conditions for the lower elevations through Saturday night with copious amounts of Pacific moisture moving through the region. Cancelled the High Wind Warning for the western foothills as winds failed to materialize at the surface ahead of the Pacific front. Could see some light snow accumulations on grassy surfaces through mid day for the lower elevations/foothills, but nothing impactful. Another surge of Pacific moisture arrives for Saturday along with a more significant cold front from the northwest.
407 AM CST Fri Mar 1 2024 -Breezy, dry and warmer conditions expected today through the weekend.
231 AM MST Fri Mar 1 2024 Cold front currently moving through eastern Montana early this morning. Cooler temperatures will move in today that will still be above normal for early March. Upper trough and low moves inland from the Pacific tonight and Saturday.
A passing system will bring gusty winds, cooler temperatures, and chances for precipitation through the weekend.
502 AM CST Fri Mar 1 2024 (Today through Saturday afternoon) Much warmer conditions are expected today with highs climbing into the 70s areawide. Increasing southwesterly flow aloft Saturday will bring some gusty winds to the higher terrain and SE NM.
516 AM CST Fri Mar 1 2024 (Today) Satellite imagery shows a low pressure system spinning across northeast OK/southeast KS this morning. With sfc dewpoints as of 07z still in the low to mid 20s, any returns on radar early this morning will likely remain as virga until better moisture arrives by sunrise.
823 AM EST Fri Mar 1 2024 High pressure will cross the region today.
522 AM CST Fri Mar 1 2024 (Today and tonight) Much warmer temperatures expected today across west central Texas with highs in the mid to upper 70s after a chilly start this morning as temperatures drop into the lower 30s. The upper level low that brought showers and a few thunderstorms and very cool temperatures to the area yesterday has already moved out the area tonight. With the low moving out, upper level heights will rise significantly tomorrow, along with 850mb temperatures that will be 10 to 15 degrees Celsius warmer.
This is thanks to the rainfall from yesterday as well as cooling temperatures as overnight lows fall into the mid to upper 30s across North Texas and into the low 40s across Central Texas. Much warmer temperatures can be expected as we kick off the weekend and the first day of March, with highs today reaching into the mid to upper 70s out west and into the mid to low 70s in the east. The well above normal temperatures are in response to a deepening cyclone along the Front Range that will eventually be sending a cold front southward into North and Central Texas by the middle of the week.
Southerly to southwesterly winds at the 850mb layer will bring in warmer air, resulting in warmer surface temperatures for today. Cloud cover should once again decrease late morning into the afternoon hours Saturday, allowing for more heating and consequently warmer highs.
This leads to much warmer temperatures with highs up to 5 degrees above normal for today. The low clouds and fog erode by midday on Saturday. Southwesterly flow off the surface leads to even warmer temperatures with highs about 10 degrees above normal.
The abundant cloud cover should lead to a mild day with highs ranging from the lower 60s near the coast, mid to upper 60s along the I-69C/US Hwy 281 corridor and the lower 70s across the Rio Grande Plains. However, the temperatures will be highly dependent on the movement on the coastal trough as it moves away and how quickly the cloud cover erodes. Saturday will be warmer with highs generally in the upper 70s to the low to mid 80s. Have lean towards a blend of the cooler CONSShort/NAM with the NBM for temperatures for today then back towards the NBM tonight and Saturday.
Warmer temperatures today as dry weather returns to the area.
(Today) Mid and upper level low currently centered over Southeast Kansas early this morning will continue to lift off to the northeast today. with the backside of the low clearing Eastern Oklahoma and Northwest Arkansas this afternoon.
405 AM EST Fri Mar 1 2024 High pressure will cross the region today.
For the weekend, the upper pattern will feature a trough in the west, while a ridge builds over the eastern half of the country.
The upper level system that brought us precipitation yesterday will continue its track eastward out of the region, while to our west an upper level trough begins to deepen across western CONUS, resulting in relatively zonal to northwest flow aloft with dry and pleasant weather across the region. At the surface lee troughing over northeast NM will lead to breezy west winds on the Caprock Friday afternoon around 15 to 20 mph. Otherwise, expect temperatures Friday night to be warmer than previous in the upper 30s to low 40s.
206 AM MST Fri Mar 1 2024 Quick Synopsis: Winds diminish over the western foothills early this morning, heavy mountain snow into the weekend, unsettled conditions for the lower elevations through Saturday night with copious amounts of Pacific moisture moving through the region. Cancelled the High Wind Warning for the western foothills as winds failed to materialize at the surface ahead of the Pacific front. Could see some light snow accumulations on grassy surfaces through mid day for the lower elevations/foothills, but nothing impactful. Another surge of Pacific moisture arrives for Saturday along with a more significant cold front from the northwest.
432 AM CST Fri Mar 1 2024 (Today) Mid and upper level low currently centered over Southeast Kansas early this morning will continue to lift off to the northeast today. with the backside of the low clearing Eastern Oklahoma and Northwest Arkansas this afternoon.
(Today and tonight) Much warmer temperatures expected today across west central Texas with highs in the mid to upper 70s after a chilly start this morning as temperatures drop into the lower 30s. The upper level low that brought showers and a few thunderstorms and very cool temperatures to the area yesterday has already moved out the area tonight. With the low moving out, upper level heights will rise significantly tomorrow, along with 850mb temperatures that will be 10 to 15 degrees Celsius warmer.
Areas along the Nature Coast are expected to have the highest chances today, but the rest of us have a slightly higher chance on Saturday. During the second half of the weekend, the aforementioned trough and cold front slowly lift north of the area.
Some snow was even seen in the higher terrain areas across the W/NW. with warmer lows in the upper 40s to mid 50s.
This weekend, a large low pressure system over the northeast Pacific will move slowly inland along the West Coast. Winds are expected to be strongest Saturday afternoon and night with gusts to 70 to 80 mph and isolated gusts to 90 mph with the strongest winds over the mountain ridges onto the desert mountain slopes.
And this may be where the highest rainfall numbers land.
Water vapor imagery highlights a mean-layer ridge centered over Central America. Temperatures across the Keys are in the lower 70s with dewpoints in the upper 60s. High pressure centered initially near the Delmarva will slide east into the western North Atlantic over the next several days.
409 AM MST Fri Mar 1 2024 Warmer temperatures today as dry weather returns to the area.
-Breezy, dry and warmer conditions expected today through the weekend.
1016 AM EST Fri Mar 1 2024 High pressure will cross the region today.
305 PM EST Fri Mar 1 2024 Low pressure along the Gulf Coast will spread precipitation across the region tonight as it tracks toward the DelMarVA by Saturday night.
Showers are generally exiting to the east as low pressure slides along the northern GoM.
The 12z sounding at KEY sampled a moist boundary layer up to around 825 mb, capped by a distinct temperature inversion associated with a persistent mid-level ridge extending from the Yucatan Peninsula eastward into the western Caribbean. From synopsis, high pressure centered just offshore of the Delmarva Peninsula will continue to slide eastward into the western North Atlantic this afternoon and tonight, resulting in moderate to fresh east to southeast breezes.
(Through Saturday) A stagnant frontal boundary draped along the Forgotten Coast into the Suwannee Valley and a lifting upper low near Lake Michigan will maintain areas of cloudiness mixed with periods of showers (isolated thunder possible) through the near-term period. The low-temperature forecast calls for low 60s outside of roughly a Dothan-to-Fitzgerald line, northward where a CAD-like conditions drop readings to the low/mid 50s. Patchy fog is also possible, but confidence was only high enough to explicitly mention over Apalachee Bay thanks to SE flow overriding those cooler/shallow waters.
Warmer and most consistent and a little stronger southwest flow develops on Saturday and will allow to reach the low to mid 80s.
1040 AM MST Fri Mar 1 2024 Warmer temperatures today as dry weather returns to the area.
, flattening the ridge that has been in place. This will continue to advect warm and moist air over the area, with high temperatures in the low 80s. Despite the increasing moisture and flattening ridge, there will be just enough suppression to keep rain chances low (15%), with only some brief passing showers possible. On Saturday, a mid-level impulse will dig the aforementioned trough a little further south, over Central FL. Southeast winds around 10 mph will continue, and high temperatures will be in the low to mid 80s.
For Saturday, upper forcing moves east early in the day with ridging aloft building into the area during the afternoon and evening. A warmer day is store for the area.
In the low- and mid-levels, clouds are streaming in from the east to southeast. Surface analysis now places a strong, 1036 mb area of high pressure now centered just east of the Jersey Shore, with a weak stationary front draped across North Florida. This dominant high along with a strong mid-level ridge centered over the western Caribbean will act to largely deflect any synoptic disturbances north of the Florida Peninsula.
Along the Red River, sites will most likely see the low to mid 60s for highs if clouds hold, thus trended 2-3 degrees cooler for highs at SHV and TXK. Slow improvement to the cigs/FG is expected after daybreak Saturday, and while the vsbys should slowly improve by mid- morning, the low cigs will not lift/scatter out until the end of the 18Z TAF period, if not later in the afternoon.
