Slight veering of winds to more westerly towards sunrise might allow weak moisture advection from the lake which, coupled with sub-cloud sublimation, could help moisten the low levels enough to squeeze a few light snow showers out north of I-80. KEY MESSAGES: - Dry weather and warming temperatures continue under building high pressure.
1205 AM EST Sun Mar 9 2025 High pressure will prevail through the early part of the week offering dry weather along with a warming trend. Lows will be mainly in the lower 30s. Warming trend will have commenced with highs in the lower to mid 50s and lows in the lower to mid 30s.
High pressure will remain in place across the Northern Rockies this afternoon, bringing a mix of clouds and sun, with daytime temperatures running 5 to 10 degrees above normal. South- southwest winds will increase this afternoon and evening, with gusts of 15-25 mph in valleys and 30-50 mph across the higher terrain, especially in northwest Montana, as the gradient tightens with an approaching Pacific cold front in eastern Washington.
955 PM EST Sat Mar 8 2025 High pressure will prevail through the early part of the week along with a warming trend. Lows will be mainly in the lower 30s. Warming trend will have commenced with highs in the lower to mid 50s and lows in the lower to mid 30s.
326 AM CDT Sun Mar 9 2025 Updated at 326 AM CST Sun Mar 9 2025 - Showers will move through the area today, with the highest chances (60-70%) across north Mississippi.
Given the influence of the system this afternoon, temperatures will be on the cooler side, with highs in the low to mid 50's, with some upper 50's scattered across the southern counties and parishes. NBM, when compared to the other various MOS guidance was a tad warmer. Elected to trend close to the previous forecast package for highs, but did favor the somewhat warmer solution that the NBM presented, give or take a few degrees cooler when compared to the original output. Upper ridging will build into the region following the trough, and remain in place through mid-week.
With the slow movement of the passing upper low, the precipitation is expected to last well into Monday. Temperatures today are expected to top out in the low 60s north of Highway 84 to around 70 along and south of the I-10 corridor. Low temperatures in the upper 40s to around 50 are expected tonight, dropping into the low to mid 40s Monday night as clearing skies allow for better radiational cooling.
509 AM MDT Sun Mar 9 2025 - High pressure will bring sunny skies and seasonably warm temperatures into the early part of the week.
With high pressure overhead on Monday, a pleasant day is expected with highs near 70 and lows in the 40s across most of the area.
617 AM CDT Sun Mar 9 2025 Updated at 610 AM CDT Sun Mar 9 2025 - Showers will move through the area today, with the highest chances (60-70%) across north Mississippi.
A cold front approaches the area from the northwest late in the period with SHRA and TSRA possible after 10/09Z. South-southwest winds around 6-12 knots will prevail with some higher gusts possible by the end of the period as the cold front approaches the area. While suppressed somewhat, high pressure is still hanging on to control at the surface across the region, with a WSW flow in place and a drier airmass aloft. Over the next 24 hours or so, the low over TX and OK will sink a little farther south and move a lot farther east, arriving over the Florida panhandle by this time tomorrow. Overnight and into Monday, however, winds will begin to increase as an area of low pressure and associated cold front approaches.
1021 AM EDT Sun Mar 9 2025 High pressure will prevail through the early part of the week offering dry weather along with a warming trend. Low temperatures in the lower and middle 30s. In dry airmass -- abundant sunshine and WAA will allow temperatures to warm to highs in the lower and middle 60s.
Radar returns are present in our region, but the lower levels of the atmosphere are very dry, so expect mainly virga as the most impactful weather this morning.
- Breezy winds are expected today and Monday, then increasing behind a cold front Monday afternoon. Strong upper ridging is persisting across the western CONUS and building across the northern Great Plains. High clouds are streaming into the region this morning, along the top of the ridge. Dry weather and sunshine (aside from the high clouds) will continue today, with highs mostly in the 60s. Even this may end up being too cool, as some temps may sneak into the lower 70s. Warm air advection will continue tonight into Monday, with more locations reaching the lower 70s, especially across central SD.
An area of high pressure will remain over the Southwest through Monday, before unsettled weather returns.
Increasing rain and storm chances are still expected overnight into Monday morning as a cold front moves through the area. A cold front approaches the area from the northwest late in the period with SHRA and TSRA possible after 10/09Z. South-southwest winds around 6-12 knots will prevail with some higher gusts possible by the end of the period as the cold front approaches the area. High pressure ridging across south Florida and into the eastern gulf will keep a southerly wind flow around 10-15 knots and seas 2 feet or less through the day. The next weather system is taking shape over the northern gulf coast states and will bring scattered showers and isolated storms to the area late this evening through Monday afternoon as the area of low pressure and cold front move through the area.
The result is that temperatures are rising across the island chain into the upper 70s, on track to reach the lower 80s. Dew points are safely in the lower 70s so brace for more humidity. Overall, Sunday afternoon will be another great day for boating, so enjoy sunny skies and light winds before tomorrow's cold front. A low pressure system developing this afternoon, while moving eastward along the northern Gulf Coast, will result in a cold frontal passage across the Florida Keys late Monday with greater confidence for showers and thunderstorms Monday afternoon. Post cold front, expect breezes to slacken to gentle to moderate and veer easterly by mid week as high pressure builds over the Gulf (12Z TAFS) VFR and dry conditions will prevail at both EYW and MTH today.
(Tonight through Monday Night) A low pressure system is making its way east tonight and into tomorrow night. South of I-40, showers are expected to continue into Sunday night with this low pressure system.
922 AM EDT Sun Mar 9 2025 - Sunny and warmer today; Mostly Clear tonight. Plentiful sunshine and subtle warm air advection will support warmer temperatures compared to yesterday. Synopsis: Surface analysis early this morning shows a broad, elongated area of high pressure stretching from KS and MO to the Ohio Valley. Low pressure was found south of Louisiana. Aloft, strong ridging was in place over CA and NV, with quick NW flow spilling from that ridge across the upper midwest and into Indiana and Ohio. Models show the elongated high pressure area remaining over Indiana and the Ohio valley. This is mainly due to subsidence remaining in play due to the deep upper low passing across the deep south and ongoing lee side subsidence amid the northwest flow in place aloft.
604 AM EDT Sun Mar 9 2025 High pressure will prevail through the early part of the week offering dry weather along with a warming trend. Warming trend will to continue with highs from the lower 50s north to the upper 50s south. Low temperatures in the lower and middle 30s. In dry airmass -- abundant sunshine and WAA will allow temperatures to warm to highs in the lower and middle 60s.
High pressure ridging will continue to be the dominant synoptic weather player for southeast Idaho over the next several days, supporting a break between storm systems with dry conditions and a continued warming trend. A few patches of freezing fog will be possible again this morning (in places like near Idaho Falls and Bear Lake), but nothing widespread.
600 AM EDT Sun Mar 9 2025 - Sunny and warmer today; Mostly Clear tonight. Synopsis: Surface analysis early this morning shows a broad, elongated area of high pressure stretching from KS and MO to the Ohio Valley. Low pressure was found south of Louisiana. Aloft, strong ridging was in place over CA and NV, with quick NW flow spilling from that ridge across the upper midwest and into Indiana and Ohio. Models show the elongated high pressure area remaining over Indiana and the Ohio valley. This is mainly due to subsidence remaining in play due to the deep upper low passing across the deep south and ongoing lee side subsidence amid the northwest flow in place aloft.
613 AM CDT Sun Mar 9 2025 (Today through Monday) Gusty winds persist early this morning in the wake of the cold front that moved through last night. Temperatures will be much cooler today with the cooler air mass in place, expect highs only in the upper 60s and lower 70s despite mostly sunny skies. Expect warmer temperatures tomorrow with highs in the 70s to around 80.
Given recent cold snap that may lead to cold biases in ensemble model output and the expected synoptic pattern, latest forecast nudged high temperature closer toward 75th-90th percentile outcomes, meaning mid 50s for southeast OH to mid 40s in northwest PA and the higher terrain. Localized temperature fluxes are possible with terrain differences (cooler in valleys; warmer at hill tops) and may not be fully captured in the forecast. KEY MESSAGES: - Dry weather and warming temperatures continue under building high pressure.
910 AM PDT Sun Mar 9 2025 Dry and warmer today with high temperatures reaching the mid seventies in the inland valleys, about 4 to 6 degrees above seasonal averages.
320 PM CDT Sun Mar 9 2025 Updated at 320 PM CDT Sun Mar 9 2025 - Showers will continue this evening, with the highest chances (60-70%) across north Mississippi.
Temperatures will drop into the lower to mid 30s. The warming trend will continue with highs in the lower to mid 60s and lows in the upper 30s to mid 40s.
Temperatures are rising into the lower 80s with dew points creeping up towards the low to mid 70s. A Gulf Low centered along the southern coast of Alabama and Mississippi fueled heavy rain and severe thunderstorms over northern Florida and will send a cold front into the Gulf.
The low clouds and fog in Roseburg should burn off late this morning with mostly clear skies in the afternoon. Radar image is not showing anything and a look at some of the high res guidance suggest it will remain dry through this afternoon, and possibly into tonight.
Scattered to numerous showers and storms follow for tonight, with the highest coverage over interior areas. /29 (Now through Monday night) A positively tilted upper trof located over the south central states into northern Mexico takes on a meridional orientation while progressing across the southeastern states on Monday, and then continues off into the western Atlantic Monday night. Rain chances end from west to east Monday morning as the upper trof moves across the area with drier air flowing into the area. Lows tonight range from the mid/upper 40s well inland to the lower 50s closer to the coast.
1212 PM CDT Sun Mar 9 2025 Updated at 1208 PM CDT Sun Mar 9 2025 - Showers will move through the area today, with the highest chances (60-70%) across north Mississippi.
Much warmer weather will bring a glimpse of Spring this week, with mostly dry conditions. By dawn Monday, most of the area will have already climbed slightly above freezing. Tomorrow will be another dry day, however winds will be much lighter with high pressure overhead. Ridging will continue to build tomorrow night and temperatures will remain warm overnight with lows staying in the upper 30s for much of the region.
130 PM EDT Sun Mar 9 2025 High pressure will prevail through the early part of the week offering dry weather along with a warming trend. Low temperatures in the lower and middle 30s. In dry airmass -- abundant sunshine and WAA will allow temperatures to warm to highs in the lower and middle 60s.
An upper-level high pressure ridge over our region today will deliver another warm, dry day. High clouds will gradually increase throughout the day as an upper-level trough approaches for Monday.
Pleasant conditions continue under high pressure this afternoon as high temperatures are expected about 10 degrees above normal. South- southwest winds will increase this afternoon and evening, with gusts of 15-25 mph in valleys and 30-50 mph across the higher terrain, especially in northwest Montana, as the gradient tightens with an approaching Pacific cold front. As the cold front presses through tonight and Monday morning, high resolution guidance suggests wind gusts of 35-45 mph across northwest Montana valleys, slightly lower for other valleys of western Montana.
1131 AM MDT Sun Mar 9 2025 - High pressure will bring sunny skies and seasonably warm temperatures into the early part of the week.
133 PM PDT Sun Mar 9 2025 Dry and warmer today with high temperatures reaching the mid seventies in the inland valleys, about 4 to 6 degrees above seasonal averages.
Temperatures over the the snow cover is in the low to mid 50s while readings have risen into the 60s over the south. The snow cover should continue to melt excessively this afternoon but with overnight low temperatures falling back into the low 30s, the melting will slow quickly and there likely will be some lingering snow cover/wet ground to begin the day Monday. A strong push of thermal advection will arrive tonight into Monday as the thermal ridge moves into Iowa ahead of a short wave trough that will pass through Monday night. The record highs on Monday are relatively low in the upper 60s to mid 70s as they are the lowest record highs by several degrees going forward in March so do expect a few records.
246 PM MDT Sun Mar 9 2025 KEY MESSAGES: - There are High Wind Watches/Warnings for strong winds Monday as a cold front moves through.
However the lower levels of the atmosphere are very dry with many weather stations reporting a 30+ degree dew point depression, with measurable rain not reaching the ground for most places until you get to Interstate 20 or south further south. Expect skies to clear out throughout the day on Monday leading to temperatures about 5 degrees warmer than today.
Today: The frontal boundary is forecast to stall out, while an upper low over the southern Plains is expected to move over the Gulf Coast states. Overnight lows are expected to be near average in the lower to mid 40s. Key Message(s): - Periods of moderate rain and isolated thunderstorms continuing through Monday with cooler conditions continuing. As the upper level low pushes east of the area Monday night, drier air will shift into the forecast area. Blended guidance has remained consistent with 40 to 70 percent probability of total rainfall over an inch with the highest probs in the southeastern portion of the forecast area. Went a bit below blended guidance for highs on Monday, in the low to mid-50s but some guidance is indicating that temperatures may struggle to break out of the 40s.
1157 AM CDT Sun Mar 9 2025 (Today through Monday) Gusty winds persist early this morning in the wake of the cold front that moved through last night. Temperatures will be much cooler today with the cooler air mass in place, expect highs only in the upper 60s and lower 70s despite mostly sunny skies. Expect warmer temperatures tomorrow with highs in the 70s to around 80.
(This evening through Monday) High pressure will slowly settle into West Central Texas tonight, with winds becoming light and variable overnight, and skies continuing to clear out of the area. With mostly clear skies tonight and some radiational cooling expected, cooler overnight low temperatures in the 30s are expected overnight tonight into Monday morning. Overnight lows will remain well above freezing for the rest of the week.
1212 PM EDT Sun Mar 9 2025 - Sunny and warmer today; Mostly Clear tonight. Plentiful sunshine and subtle warm air advection will support warmer temperatures compared to yesterday. Synopsis: Surface analysis early this morning shows a broad, elongated area of high pressure stretching from KS and MO to the Ohio Valley. Low pressure was found south of Louisiana. Aloft, strong ridging was in place over CA and NV, with quick NW flow spilling from that ridge across the upper midwest and into Indiana and Ohio. Models show the elongated high pressure area remaining over Indiana and the Ohio valley. This is mainly due to subsidence remaining in play due to the deep upper low passing across the deep south and ongoing lee side subsidence amid the northwest flow in place aloft.
An upper level low pressure system will continue to move through the southern Gulf states through the night but no impacts are expected locally as even the northern extent of the clouds gets to around Tennessee. Lows tonight are expected to fall into the upper 30s with temperatures forecast to remain above freezing over the next 7-10 days.
Tonight and Monday It's a beautiful late winter Sunday across eastern Idaho as high pressure remains in control of local weather. Temperatures have warmed nicely into the 40s and 50s across many of the lower valleys where snowpack has already melted. This will bring a slight increase of winds to the area as well as a bit more cloud cover but temperatures will continue to run on the warmer side of normal.
Patchy drizzle and scattered showers persist, mainly along and north of I-20 as an upper trough moves across the ArkLaTex. The trough may move more southeasterly this afternoon, which bring more of the showers and drizzle farther southeast into Louisiana and East Texas. Given the influence of the system this afternoon, temperatures will be on the cooler side, with highs in the low to mid 50's, with some upper 50's scattered across the southern counties and parishes. NBM, when compared to the other various MOS guidance was a tad warmer. Elected to trend close to the previous forecast package for highs, but did favor the somewhat warmer solution that the NBM presented, give or take a few degrees cooler when compared to the original output. Upper ridging will build into the region following the trough, and remain in place through mid-week.
(This evening through Monday) High pressure will slowly settle into West Central Texas tonight, with winds becoming light and variable overnight, and skies continuing to clear out of the area. With mostly clear skies tonight and some radiational cooling expected, cooler overnight low temperatures in the 30s are expected overnight tonight into Monday morning.
Skies will gradually become mostly clear late this afternoon as drier and cooler air filters in and the main low moves out of the region.
255 PM CDT Sun Mar 9 2025 Through tonight: The closed upper low, centered over the ArkLaTex region as of mid afternoon, will be the primary weather driver as we go through the near term. Moist ascent will be most pronounced in the deformation zone north of the low center, which is expected to move into northwest portions of the area by early evening, then track to east central MS prior to daybreak.
A pleasant afternoon rounds out the weekend courtesy of high pressure. Southwesterly flow has contributed to slightly warmer temperatures today, with observations at the time of writing ranging in the 40s and 50s. After another night of sufficient radiational cooling, Monday morning lows will bottom out into the low 30s. Ongoing warming trend will result in afternoon highs rising into the 60s for much of the lower elevations and low to mid 50s along the higher terrain.
Breezy southwest flow continues on Monday, ahead of a cold front that will pass through the region late Monday night.
729 PM CDT Sun Mar 9 2025 Through tonight: The closed upper low, centered over the ArkLaTex region as of mid afternoon, will be the primary weather driver as we go through the near term. Moist ascent will be most pronounced in the deformation zone north of the low center, which is expected to move into northwest portions of the area by early evening, then track to east central MS prior to daybreak.
A little farther to the north and west, an area of low pressure continues to develop over the northern gulf coast near Louisiana/Mississippi. The associated warm front and stationary boundary extends eastward from the low along the northern gulf coast, along the GA/FL line and into the western Atlantic. The associated cold front remains well to the west in the west-central gulf. These features will traverse eastward over the next 24 hours, with the cold front moving through the area late this evening into the early morning hours on Monday. Latest guidance has most of the shower and storm activity south and east of the area by sunset on Monday as high pressure builds in from the west producing clearing conditions through the end of the week.
High pressure over the area will shift east and flatten for the early part of the week.
Clear skies will allow for temps to dip into the lower to mid 30s, with a few upper 20s expected in rural/low-lying/sheltered locales. The warming trend will continue with highs in the lower to mid 60s and lows in the upper 30s to mid 40s.
Low pressure passage this weekend will promote widespread rain and a downward trend in temperature. On the other hand, clear skies and radiative cooling may allow some valleys insulated from the wind to cool a bit more than hilltops, into the low 30s and upper 20s. KEY MESSAGES: - Dry weather and warming temperatures continue under building high pressure.
358 PM MDT Sun Mar 9 2025 - High pressure will bring sunny skies and above normal warmth early this week.
540 PM CDT Sun Mar 9 2025 Updated at 529 PM CDT Sun Mar 9 2025 - Showers will continue this evening, with the highest chances (60-70%) across north Mississippi.
520 PM MDT Sun Mar 9 2025 - High pressure will bring sunny skies and above normal warmth early this week.
Deep layered ridging is shifting east and southeast of our area. This steady breeze will likely hold overnight lows near current readings in the lower 70s and dew points climbing a couple or few degrees into the lower 70s. The lower level inhibition is expected to weaken while the boundary layer continues to moisten.
A pleasant afternoon rounds out the weekend courtesy of high pressure. Southwesterly flow has contributed to slightly warmer temperatures today, with observations at the time of writing ranging in the 40s and 50s. After another night of sufficient radiational cooling, Monday morning lows will bottom out into the low 30s. Ongoing warming trend will result in afternoon highs rising into the 60s for much of the lower elevations and low to mid 50s along the higher terrain. Windy conditions will take hold for Tuesday as the pressure gradient tightens across the area from a passing disturbance to the north, with a moisture starved cold front moving south towards our area.
Large area of high pressure remaining in charge with a stout ridge pattern aloft. A weak cold front looks to approach from the west tonight into Tuesday. Windy conditions will take hold for Tuesday as the pressure gradient tightens across the area from a passing disturbance to the north, with a moisture starved cold front moving south towards our area.
(Today through Tuesday) High pressure in control means the short term forecast period is very quiet. Locations along the coast will be slightly cooler as water temperatures in the mid 60s will keep air temps down. High temperatures go up tomorrow with the ridge to our east and mid to upper 80s are expected along and west of Hwy 281.
102 AM CDT Mon Mar 10 2025 As the upper low moves across the area this evening Isolated to scattered showers and storm are occuring, mainly along and north of I-20. Through tonight: The closed upper low, centered over the ArkLaTex region as of mid afternoon, will be the primary weather driver as we go through the near term. Moist ascent will be most pronounced in the deformation zone north of the low center, which is expected to move into northwest portions of the area by early evening, then track to east central MS prior to daybreak.
