1103 AM EST Mon Jan 13 2025 Low pressure will continue to move east across the northern Gulf of Mexico. - The small risk for freezing rainfall this morning appears to have ended. 03 inch) freezing rain south of Interstate 20 and north of Macon. This risk appears to be dissipating and may have flown the coup entirely due to cloud cover (a hindrance for additional cooling) and surface temperatures that are still above freezing as of 230 AM. Should any precipitation overcome the dry air and the limitations above, then road temperatures that area above freezing should prevent any significant impacts. Thus forecast confidence in no impacts from freezing precipitation this morning is high (95%). Northwest winds will become more persistent as the high builds in and this should prevent fog from being a concern tonight.
pdf An area of low pressure over the northern Gulf will move east southeast Today. Rain showers extending east from the low will move southeast across area as the low moves southeast. Strong high pressure will build to the northwest overnight, with skies beginning to clear from northwest to southeast. Lows will dip to around freezing over inland SE GA, while lows in the mid 40s are expected for north central FL.
Wind chills will drop into the low to mid 20s across the area.
The first one is a warm front that is draped over central Florida right now. This front will push through quickly this evening with the cold front not far behind it. The cold front will bring some passing showers overnight but not expected any significant rainfall totals. This cold front will help to keep temperatures cooler through most of our work week with highs in the 60's and lows in the 40's.
1111 AM CST Mon Jan 13 2025 - Refreezing and black ice concerns for the morning commute continue for most of the week.
257 PM EST Mon Jan 13 2025 (This afternoon through Tuesday) Low pressure continues to move east across the northern Gulf of Mexico. The low should make landfall along the central west coast of Florida early this evening, cross the peninsula overnight and move out to sea by early Tuesday. Regional radar shows a broad shield of light precip well to the north of the low center, but the higher reflectivities have moved well south of the CWA. As the low center moves off into the western Atlantic, high pressure will build back in from the west.
A surface cold front is also currently moving into far northwestern Alabama counties with another shot of colder and drier air behind it.
1232 PM PST Mon Jan 13 2025 * Breezy northeast winds across Sierra ridges and chilly temperatures will continue through Tuesday morning. * A cold front may bring another round of gusty northeast winds and cooler temperatures this weekend.
1229 PM EST Mon Jan 13 2025 Cold and dry conditions through much of the week as a series of high pressure centers move over the area. A weak and dry cold front crosses the area tonight.
1233 PM EST Mon Jan 13 2025 A series of cold fronts tonight and Tuesday night will maintain dry weather and below normal temperatures for most of this week.
A weak low pressure system over the Pacific will move inland late in the week, though it will lack significant moisture and will mainly result in increased cloud cover across Northwest Arizona. Surface obs showed breezy north winds and temperatures slightly cooler than 24 hours ago. Otherwise, temperatures will warm a few degrees tomorrow as the low gets farther away and heights rise.
(This evening through Tuesday Night) Fairly quiet weather is expected through tomorrow as high pressure remains situated just to the north.
1256 PM EST Mon Jan 13 2025 Cold high pressure will build into the middle Ohio Valley today.
1110 AM CST Mon Jan 13 2025 (Today through Tuesday Night) A new cold front is dropping SE through the state early this Mon morning. Other than residual issues from melting snow refreezing in areas with below freezing temps. The cold front will push SE of the state by later today. Temps will end up cooler overall for this afternoon. Highs will be in the low 30s to mid 40s. with temps warming back up into the low 40s to low 50s for highs on Tue.
Patchy fog in the Western Magic Valley is expected to dissipate by this afternoon, but the low stratus may persist. Otherwise, expect a dry north-northeast flow aloft with partly to mostly cloudy skies today as an upper ridge resides off the west coast. An area of high pressure building in from off the coast will keep northerly flow over the area.
- Warmer and rainy to end the week. (Rest of today through Tuesday) Current surface observations show all sites now have winds out of the north, thus the cold front has moved through. (Tuesday Night through next Monday) Another mostly dry cold front will push through Tuesday evening bringing a period of increased clouds and even colder air. If clouds clear out, lows will once again drop off to the low 20s to upper teens.
Dry weather and below average temperatures will last through midweek as a trough sits over the area. A fast moving ridge will allow temperatures to warm up the second half of the week before another trough moves in and drops temperatures below average again by the weekend.
302 PM EST Mon Jan 13 2025 A series of cold fronts tonight and Tuesday night will maintain dry weather and below normal temperatures for most of this week.
227 PM CST Mon Jan 13 2025 - Mostly quiet weather week with the passage of another cold front and snow cover maintaining the below normal temperatures. Per water vapor imagery this afternoon, three vort maxes within an elongated northwest troughing pattern aloft stretches from southern CA to the upper Midwest region. Skies become partly sunny in the afternoon as forecast highs are a few degrees cooler in the low 20s.
1141 AM CST Mon Jan 13 2025 Post-frontal cold air advection is expected to limit temperature rise today with most locations running some 8-10 degrees cooler compared to yesterday's highs.
1115 AM CST Mon Jan 13 2025 Post-frontal cold air advection is expected to limit temperature rise today with most locations running some 8-10 degrees cooler compared to yesterday's highs. /19/ (Monday through Tuesday) Slightly cooler than normal conditions will continue into the middle of the week across the Four State Region. This is due to post-frontal cold air advection introducing drier air and maintaining temperature maximums/minimums in the lower 50s/lower 30s respectively. Convergent, zonal flow aloft will suppress active weather with subsequent surface ridging maintaining light winds and temperature maximums/minimums above- normal in the 60s/40s respectively.
1002 AM EST Mon Jan 13 2025 A series of cold fronts tonight and Tuesday night will maintain dry weather and below normal temperatures for most of this week.
221 PM CST Mon Jan 13 2025 - Refreezing and black ice concerns for the morning commute continue for most of the week.
- A few light snow showers continues through early Tuesday morning across the higher terrain and northerly upslope areas.
(Now through Tuesday night) Zonal flow aloft will persist through the near term between upper high pressure roughly centered over the Caribbean Sea and a large and persistent positively tilted upper trough over much of the CONUS. Highs on Tuesday should manage to reach the lower to middle 50s, A high risk of rip currents remains in effect through tonight, then a moderate risk follows for Tuesday with a low risk for Tuesday night.
In fact, most areas will likely bottom out somewhere in the 20s while a few of our far west to southwest zones may only manage the lower 30s. A modest warm-up will follow on Tuesday with the advancing high pressure ridge at the sfc.
After a warmer afternoon with highs in the 40s and 50s, the clear skies and calm winds will support an ideal environment for radiational cooling allowing for temps to drop into the high teens and the low twenties by early tomorrow morning.
251 PM MST Mon Jan 13 2025 - A few light snow showers continues through early Tuesday morning across the higher terrain and northerly upslope areas.
A weak closed upper low off the coast of SoCal moved through this morning, leading to a brief period of gusty winds that are still lingering in some areas, but are easing through midday.
- Warmer and rainy to end the week. High pressure is locked in over Middle Tennessee and we've got the dry, stable sounding to prove it.
The highest snowfall totals will fall across south central South Dakota.
The collapsing winds overnight will allow the temperature gradient between the cooler Gulf and the warmer water to our south to create their own wind. The good news is that any fog that does form shouldn't last too long as the winds will increase due to a cold front approaching from the Gulf. Guidance is ultimately offering two different solutions, because the global models extrapolate the troughing in the central U. Areas of fog will be possible in portions of the Bayside waters and the Deep Gulf during the early morning hours, but confidence is on the lower side due to marginal conditions. Another cold front is progged to push through the Keys marine zones Tuesday afternoon and evening, with a northerly wind surge expected in its wake.
544 PM CST Mon Jan 13 2025 (This evening through Tuesday Night) Fairly quiet weather is expected through tomorrow as high pressure remains situated just to the north.
305 PM CST Mon Jan 13 2025 Through Tomorrow: In the wake of a cold front passage today, mostly clear skies and building high pressure will set up good radiational cooling potential. It's not the most ideal given some increased soil moisture, but we expect a widespread frosty morning with temps ranging from the lower to mid 20s in our northern zones to upper 20s/near 30 in our southern zones. Then fair and dry conditions continue into tomorrow daytime as the chilly post- frontal air brings us widespread high temperatures in the lower to mid 50s.
(This afternoon through Tuesday) Low pressure continues to move east across the northern Gulf of Mexico. The low should make landfall along the central west coast of Florida early this evening, cross the peninsula overnight and move out to sea by early Tuesday. Regional radar shows a broad shield of light precip well to the north of the low center, but the higher reflectivities have moved well south of the CWA. As the low center moves off into the western Atlantic, high pressure will build back in from the west.
Northerly winds will overspread the remainder of the area overnight into Tuesday allowing cooler drier air to filter into the area. Cooler temps in store for Tuesday with high temps in the lower 60s north to lower 70s south, with occasionally breezy northerly winds. The first one is a warm front that is draped over central Florida right now. This front will push through quickly this evening with the cold front not far behind it. The cold front will bring some passing showers overnight but not expected any significant rainfall totals. This cold front will help to keep temperatures cooler through most of our work week with highs in the 60's and lows in the 40's.
456 PM CST Mon Jan 13 2025 - Mostly quiet weather week with the passage of another cold front and snow cover maintaining the below normal temperatures. Per water vapor imagery this afternoon, three vort maxes within an elongated northwest troughing pattern aloft stretches from southern CA to the upper Midwest region. Skies become partly sunny in the afternoon as forecast highs are a few degrees cooler in the low 20s.
Dry weather will prevail through the majority of the week into the weekend as high pressure re-builds across the Pacific Northwest.
40" QPF over the highest elevations of the Black Hills and 70-90% chance 0. Bufkit soundings depict a bit more westerly component to the wind than is usual in upslope snow events, so the highest total snow accumulations are expected to be displaced more toward the western edge of the hills, between Cheyenne Crossing, Buckhorn, and Moskee.
815 PM EST Mon Jan 13 2025 High pressure will build into the region tonight and prevail through the week. Another system and associated cold front will impact the region this weekend. At the sfc, low pressure positioned over Florida will shift east across the nearby Atlantic while dry high pressure builds across the Southeast United States in its wake. Latest satellite imagery depicts a fair amount of clouds across the local area, but with time will shift offshore as high pressure arrives from the west. Temps will be cooler than the previous night, especially late once the bulk of stratus shifts offshore and some radiational cooling component takes place.
High pressure over Western Washington will bring multiple rounds of morning fog and low stratus over the next few days.
535 PM CST Mon Jan 13 2025 (Today through Tuesday Night) A new cold front is dropping SE through the state early this Mon morning. Other than residual issues from melting snow refreezing in areas with below freezing temps. The cold front will push SE of the state by later today. Temps will end up cooler overall for this afternoon. Highs will be in the low 30s to mid 40s. with temps warming back up into the low 40s to low 50s for highs on Tue.
Ridging over the northeastern Pacific and broad troughing over central North America will keep our forecast area under general high pressure with north flow aloft. An upper level trough to our south will close off and take up position offshore of southern California and as a result, the Pacific ridge will tilt inland over the Pacific Northwest. This ridge then remains in control for the remainder of the week, either directly overhead or centered just offshore. Expect fog/freezing fog and low clouds each overnight and morning for most valleys west of the Cascades. Otherwise, temperatures will generally see a gradual warming trend through the week, although any areas in more persistent fog or low clouds may stay cooler with very little change in temperature.
612 PM CST Mon Jan 13 2025 Through Tomorrow: In the wake of a cold front passage today, mostly clear skies and building high pressure will set up good radiational cooling potential. It's not the most ideal given some increased soil moisture, but we expect a widespread frosty morning with temps ranging from the lower to mid 20s in our northern zones to upper 20s/near 30 in our southern zones. Then fair and dry conditions continue into tomorrow daytime as the chilly post- frontal air brings us widespread high temperatures in the lower to mid 50s.
502 PM CST Mon Jan 13 2025 - Refreezing and black ice concerns for the morning commute continue for most of the week.
A cold front is currently located across the central Florida peninsula, and will move southeast across the remainder of the forecast area through the early morning hours. High pressure will build over the Florida peninsula in the wake of the front today with drier cooler air advecting across the region. Mid/upper level moisture will overrun the cooler air tonight and Wednesday which will cause increasing cloudiness across west central and southwest Florida. Combination of the increasing moisture and a cold front associated with a weak U/L trough expected to move across the southeast U.
1029 PM CST Mon Jan 13 2025 - Mostly quiet weather week with the passage of another cold front and snow cover maintaining the below normal temperatures. Per water vapor imagery this afternoon, three vort maxes within an elongated northwest troughing pattern aloft stretches from southern CA to the upper Midwest region. Skies become partly sunny in the afternoon as forecast highs are a few degrees cooler in the low 20s.
Stable conditions are in place with the lowest inhibition layer based way down 980 to 990 mb. An associated cold front will advance southward through the Gulf of Mexico, but will not reach the Keys until some time on Tuesday. A rapidly weakening low pressure system driving eastward in across the Florida Peninsula overnight will result in winds becoming quite light and variable across Keys waters. It will not take much for winds to nudge northwest, potentially precipitating patchy fog due to high surface moisture and cooler water temperatures. This is due to the weak flow, high dew points and relatively cooler waters to our north.
318 AM EST Tue Jan 14 2025 Cold and dry conditions through much of the week as a series of high pressure centers move over the area. Aloft, a relatively flat ridge keeps a more westerly wind component over the CWA. Off to the west, a weak, positively tilted trough swings down over the Rockies, before diving toward the south. There could be a quick burst of snow at the TN/NC border, but confidence is low given the amplifying high pressure and lack of any real moisture. A few areas at the higher elevations could dip below zero, but remain above criteria for any cold products.
The lower conditions are expected to break to VFR by 20-22Z early Tuesday afternoon.
Meanwhile, a shortwvae trough will be dropping southeast out of the Great Lakes, which will push the jet and vort max southward, along with a surface cold front. Cloud cover will also begin to increase late in the day in northern sections with the approaching front and trough. Tonight, with a 30-40 kt NW 850 mb flow and falling temperatures aloft under the trough, we will have some scattered snow showers or flurries for a short period between 00-06Z in SW VA and the TN mountains. With the 850 mb thermal trough moving through tonight along with the winds aloft, the higher elevations of SW VA and East TN will have wind chills that could drop below zero for a short time late tonight.
Dry and warming continues through the end of the week with highs in the low 40s and lows in the 20s.
844 PM MST Mon Jan 13 2025 - A few light snow showers continues through early Tuesday morning across the higher terrain and northerly upslope areas.
- Drifting snow across roads, then melting and re-freezing, could result in slippery spots Wednesday into Wednesday evening.
Dry weather and below average temperatures will last through midweek as a trough sits over the area. A fast moving ridge will allow temperatures to warm up the second half of the week before another trough moves in and drops temperatures below average again by the weekend. Positively tilted trough that has funneled cold and dry air into the region will continue to hang around for another couple days keeping temperatures below average through Wednesday.
High pressure is coming in a for a landing over S AR with 1031mb at Greenville, MS and the 1030 contour at El Dorado and Monroe and a lone reading at Paris.
1054 PM EST Mon Jan 13 2025 High pressure will build into the region tonight and prevail through the week. Another system and associated cold front will impact the region this weekend. At the sfc, low pressure positioned over Florida will shift east across the nearby Atlantic while dry high pressure builds across the Southeast United States in its wake. Latest satellite imagery depicts a fair amount of clouds along and east of the I-95 corridor, but with time will shift offshore as high pressure arrives from the west. Temps will be cooler late night with weak cold air advection occurring, especially once the bulk of stratus shifts offshore and a radiational cooling component takes place.
Although, many sites seem slow to cool down, as they are a couple of degrees warmer than the hourly forecast. Discussion: Colder air will be moving in late this afternoon into tonight behind the exiting cold front. Shallow moisture may be enough for a few flurries/sprinkles mainly northern mountain areas late this afternoon into early evening, although these will be limited given the limited moisture and the low level flow being more westerly than ideal for orographic lift.
1042 PM CST Mon Jan 13 2025 - Below-average temperatures through Wednesday, then warmer to close out the week.
/DC/ Through Tomorrow: In the wake of a cold front passage today, mostly clear skies and building high pressure will set up good radiational cooling potential. It's not the most ideal given some increased soil moisture, but we expect a widespread frosty morning with temps ranging from the lower to mid 20s in our northern zones to upper 20s/near 30 in our southern zones. Then fair and dry conditions continue into tomorrow daytime as the chilly post- frontal air brings us widespread high temperatures in the lower to mid 50s.
1005 PM CST Mon Jan 13 2025 - Refreezing and black ice concerns for the morning commute continue for most of the week.
(Today through Wednesday) High pressure will slide into the area today and bring a very dry airmass into the region.
with temps expected to be cooler for Wed afternoon as a result. Increased clouds may also aide in keeping temps cooler for Wed.
- A reinforcing shot of arctic cold will come with another cold front's passage Tuesday. The coldest readings will be late Tuesday night into early Wednesday morning, when temperatures and wind chills bottom out in the lower single digits (north) to teens (south). A closed low over the north central US spins up an Alberta clipper overnight that moves into the area. Mid-level ridging builds in later in the week and our temperatures moderate more substantially with lows above freezing and highs in the vicinity of 50.
Another chilly morning is expected with freezing temperatures across the Hill Country, southern Edwards Plateau and northern portions of the I-35 corridor and coastal plains. High pressure over the lower Mississippi Valley will allow for light easterly to southeasterly wind across the area today, with highs in the mid 50s to low 60s. Low clouds will be across almost all of South Central Texas overnight into Wednesday, keeping lows warmer than previous nights in the low to mid 40s.
343 AM EST Tue Jan 14 2025 High pressure will prevail through the week. Another low pressure system and associated cold front will impact the region this weekend. The center of a 1030mb high will remain centered over the lower Mississippi River Valley, ridging east over the forecast area. High pressure at the surface will prevail across the local forecast area through the week.
- Patchy blowing and drifting snow is possible Wednesday as warmer temperatures move into the area. Thermal ridging builds into the area starting late this evening after a frigid day across much of the region. Much warmer air begins flowing into the region as winds become more westerly during the overnight hours. Tonight's low temps will likely occur around or just after midnight, with warmer temperatures heading further into the morning.
1239 AM EST Tue Jan 14 2025 High pressure will build into the region tonight and prevail through the week. Another system and associated cold front will impact the region this weekend.
132 AM CST Tue Jan 14 2025 - A reinforcing shot of arctic cold will come with another cold front's passage today.
Mostly clear skies and cold conditions are ahead tonight as drier air filters southward in the wake of a cold front. Expect subfreezing temperatures areawide by Tuesday morning. RW (This afternoon through Tuesday) Low pressure continues to move east across the northern Gulf of Mexico. The low should make landfall along the central west coast of Florida early this evening, cross the peninsula overnight and move out to sea by early Tuesday. Regional radar shows a broad shield of light precip well to the north of the low center, but the higher reflectivities have moved well south of the CWA. As the low center moves off into the western Atlantic, high pressure will build back in from the west.
1133 PM CST Mon Jan 13 2025 (This evening through Tuesday Night) Fairly quiet weather is expected through tomorrow as high pressure remains situated just to the north. Overnight low temperatures tonight will get down into the mid 30s to low 40s for most of the area - but near freezing temperatures are likely in the Piney Woods.
Through most of the short term period, the PacNW will be under a high pressure system before flattening Wednesday night. Low temperatures and dewpoints may reach to sub freezing during those times as well.
A quick, southward moving cold front will move through the state on Wednesday, and will promote cooler than normal temperatures.
