310 PM CST Sat Jan 11 2025 Through Sunday: Building ridge and high pressure will lock in dry air over the area through most of the short term period. Areas to the southwest will see surface winds back from the south overnight and increasing cloud cover may keep low temperatures slightly warmer there.
633 PM EST Sat Jan 11 2025 An upper-level low over New England is propagating ENE while weak ridging through the Great Lakes and Ohio River Valley is being eroded by another trough in the four corners region. In association with the low over New England, an attendant cold front pushed through the region this morning. A NW wind has settled in behind this front, advecting a cooler and drier airmass over Florida.
519 PM CST Sat Jan 11 2025 Updated at 516 PM CST Sat Jan 11 2025 - Chilly again tonight behind an evening cold front, much cooler and still breezy on Sunday. (This evening through Sunday) Quite an impressive gradient in temperatures early this afternoon with 1 PM temperatures in the low 40s across the snow-covered SW TX Panhandle, with upper 50s in the snow-free zones further south and east courtesy of warm downslope breezes. Low level cloud cover will increase behind the above-mentioned cold front, and moisture in the 850-700mb layer may be just deep enough to support a few snow flurries overnight across the SW TX Panhandle, although no impacts are expected.
331 PM CST Sat Jan 11 2025 - Accumulating snow is likely across northwest Nebraska near the Pine Ridge tonight into tomorrow morning.
(This evening through Sunday) Zonal flow becomes influences by broad upper level troughing aloft as it slowly encompasses much of the west. At the surface, high pressure builds.
- A weak cold front will move through the region tonight and Sunday, knocking temperatures back well below normal through Sunday night. This area of low pressure will move east into OK. In doing so, it will send a cold front southward early tomorrow morning. The low clouds will likely dissipate by late tomorrow morning, leaving behind mostly clear skies by the afternoon. Sunday night will be another cold one with temperatures mostly sub-freezing.
545 PM CST Sat Jan 11 2025 - Accumulating snow is likely across northwest Nebraska near the Pine Ridge tonight into tomorrow morning.
938 PM EST Sat Jan 11 2025 Low pressure will pass well south of the area tonight followed by high pressure Sunday into Sunday night.
(This evening through Sunday) Quick update to the forecast this evening to add a mention of patchy freezing across our northern tier of counties. Shortly after sunset, the area should drop down below freezing, with low temperatures Saturday morning in the upper teens in the north and lower 20s in the south. Sunday, low and mid level winds will transition to out of the southwest by the afternoon, bringing warmer air and more moisture to the southwestern counties. High temperatures will be in the low 40s in the north and the low 50s in the south, still several degrees below normal for this time of year.
Main concern will continue to be refreezing of snow on roadways tonight as temperatures will drop below freezing. Rather, concerns tonight will be more focused on the re-freeze potential as latest observations are seeing multiple locations reach into the 40s today with expectations of the cold front and present snow pack keeping lows tonight in the teens and 20s.
Winds behind a cold front will diminish this evening and overnight across eastern Nevada.
522 PM CST Sat Jan 11 2025 Updated at 518 PM CST Sat Jan 11 2025 - A cold front moves through late tonight/early Sunday morning, keeping highs below normal Sunday. While this is occurring, this pushes another cold front south through the southern Great Plains, bringing a reinforcing shot of cold, arctic air to the region. Ahead of the aforementioned trough, this afternoon's temperatures warm up nearly 10 degrees over yesterday. With the cold front tonight, frigid temperatures remain in the forecast during the morning hours. Below freezing temperatures from the mid 20s and low 30s can be expected for almost everyone to start on Sunday. The frigid morning and cold front translate into a colder afternoon as temperatures fall back below normal once again.
While this may prevent reaching optimal radiational cooling tonight, temperatures will still bottom out near to below freezing across the northern portions of the area where the ongoing Freeze Warning for inland Levy county and Frost Advisory for coastal Levy and Citrus counties will go into effect at 2 AM EST and continue through 9 AM EST Sunday. An upper-level low over New England is propagating ENE while weak ridging through the Great Lakes and Ohio River Valley is being eroded by another trough in the four corners region. In association with the low over New England, an attendant cold front pushed through the region this morning. A NW wind has settled in behind this front, advecting a cooler and drier airmass over Florida.
351 AM EST Sun Jan 12 2025 High pressure keeps cold, dry air over the forecast area today.
1102 PM CST Sat Jan 11 2025 Updated at 1100 PM CST Sat Jan 11 2025 - A cold front moves through late tonight/early Sunday morning, keeping highs below normal Sunday. While this is occurring, this pushes another cold front south through the southern Great Plains, bringing a reinforcing shot of cold, arctic air to the region. Ahead of the aforementioned trough, this afternoon's temperatures warm up nearly 10 degrees over yesterday. With the cold front tonight, frigid temperatures remain in the forecast during the morning hours. Below freezing temperatures from the mid 20s and low 30s can be expected for almost everyone to start on Sunday. The frigid morning and cold front translate into a colder afternoon as temperatures fall back below normal once again.
Dry and cold conditions will stick around through the next few days due to a large area of low pressure impacting much of the United States. An area of low pressure is still settled over Arizona, and looks to stay this way through the beginning of the work-week.
- A dry cold front will move through the region today, knocking temperatures back below normal to begin the workweek. /NEW/ /Through Monday/ A weak cold front is approaching the forecast area from the northwest early this morning, and will result in a northwest wind shift later today. Moderate cold advection will offset daytime warming which will keep highs several degrees cooler than yesterday's readings. Most areas will reach the mid 40s to mid 50s this afternoon, with overnight lows falling below freezing for most of the forecast area.
High pressure across the region today with a clear, sunny sky. Warmer today as warmer air arrives aloft, but still cool with snow pack. Most areas will nudge above freezing today as winds shift to the southwest with warmer air beginning to arrive. Snow pack across portions of the area will result in temperatures remaining slightly cooler than guidance would suggest. Temperatures drop well below freezing again tonight with any remaining moisture and snow/ice slush on roads, especially secondary roads and northward facing slopes, refreezing.
- Temperatures below freezing during nighttime hours next couple of nights will re-freeze any leftover snow, resulting in slick spots on some rural and secondary roads. Mainly clear skies and light winds will allow some patches of freezing fog to form through daybreak. Caution is advised for travelers early this morning with areas of leftover snow along with the potential for some slick spots from freezing fog. Temperatures will warm above freezing area-wide by lunchtime, and many areas will climb over 40 degrees this afternoon. For tonight through Monday morning, a cold front will cross the area.
240 AM CST Sun Jan 12 2025 - Lingering flurries/very light freezing drizzle north today with breezy northwest winds gusting 25-30+ mph.
1257 AM EST Sun Jan 12 2025 High pressure will pass east across the Ohio Valley tonight.
Otherwise light freezing drizzle and light snow late tnt and Sunday morning.
1104 PM CST Sat Jan 11 2025 (This evening through Sunday Night) Temperatures will be chilly once again across the region, with lows ranging from the mid to upper 20s across our northern and eastern zones to the lower 30s elsewhere. The HRRR, which had a really good handle on the fog development last night, is hinting once again that there could be some patchy freezing fog again tonight across our far northern zones. At the same time, a cold front will advance through our region from the north, bringing with it some reinforcing cool air. This will help temperatures drop to below freezing for most areas along and north of I-20 and then the mid to upper 30s for areas south of this point for Sunday night.
As for tomorrow, quieter weather is expected with some breezy winds in the eastern plains due to the tightening of pressure gradients from a low pressure out in the Dakotas. Cooler but quieter weather is expected tomorrow as we wrap up the weekend, as northwesterly flow aloft prevails.
1109 PM CST Sat Jan 11 2025 - Accumulating snow is likely across northwest Nebraska near the Pine Ridge tonight into tomorrow morning.
1156 PM CST Sat Jan 11 2025 - Strong cold front will push through tonight and lead to colder temperatures for Sunday and Monday.
258 AM EST Sun Jan 12 2025 High pressure will build over the area today then slide east tonight. A weak warm front will lift across the area Monday.
256 AM CST Sun Jan 12 2025 - Patchy light snow and freezing drizzle are possible through this morning. The precipitation will be very light and with temperatures near freezing, impacts will be limited.
209 AM EST Sun Jan 12 2025 High pressure keeps cold, dry air over the forecast area today. The eastern CONUS is forecast to be continually influenced by a persistent longwave trough axis, stretching from southern Canada through the southwestern US.
1044 PM CST Sat Jan 11 2025 (Tonight through Sunday night) - Sightly warmer temperatures tonight and Sunday. - A weak cold front on Sunday with a low chance (20-30%) of showers across the Coastal Plains, dry elsewhere. Lows in the low to mid 30s are forecast, with upper 20s in valleys of the Hill Country. A cold front is forecast to move through the region on Sunday. However, a few global and HREF ensemble members are generating some rain Sunday afternoon across the Coastal Plains as weak isentropic ascent north of the low develops. The cold front will re- enforce cool temperatures over the region Sunday night. However, wind speeds will remain elevated for many locations through the night, and some locations might actually experience slightly warmer temperatures but colder wind chills than tonight.
1040 PM CST Sat Jan 11 2025 Updated at 1038 PM CST Sat Jan 11 2025 - Chilly again tonight behind an evening cold front, much cooler and still breezy on Sunday. (This evening through Sunday) Quite an impressive gradient in temperatures early this afternoon with 1 PM temperatures in the low 40s across the snow-covered SW TX Panhandle, with upper 50s in the snow-free zones further south and east courtesy of warm downslope breezes. Low level cloud cover will increase behind the above-mentioned cold front, and moisture in the 850-700mb layer may be just deep enough to support a few snow flurries overnight across the SW TX Panhandle, although no impacts are expected.
1048 PM CST Sat Jan 11 2025 (This evening through Sunday) Quick update to the forecast this evening to add a mention of patchy freezing across our northern tier of counties.
Cloud cover should linger for much of the night which will keep overnight lows a bit warmer than previously forecast. Main concern will continue to be refreezing of snow on roadways tonight as temperatures will drop below freezing. Rather, concerns tonight will be more focused on the re-freeze potential as latest observations are seeing multiple locations reach into the 40s today with expectations of the cold front and present snow pack keeping lows tonight in the teens and 20s.
Ridge of high pressure at the sfc & aloft is building through the region. Lows continue to radiate this evening, with lows already falling near to below freezing. clear skies, light winds & decoupled sfc), lows will continue to radiate well into the low 20s. There is potential of some crossover in the Golden Triangle & Hwy 45 corridor, so can't rule out brief freezing fog. /DC/ Through Sunday: Building ridge and high pressure will lock in dry air over the area through most of the short term period. Areas to the southwest will see surface winds back from the south overnight and increasing cloud cover may keep low temperatures slightly warmer there.
Tomorrow morning is when the moisture and winds decrease before the upper ridge moves over inland of the PacNW tomorrow night onwards. Patchy freezing fog will also develop tomorrow through Monday.
1159 PM CST Sat Jan 11 2025 (Tonight through Sunday night) Key Message: - A weak cold front on Sunday brings a low to medium chance (20-60%) of showers across the Coastal Bend and Victoria Crossroads. Consequently, overnight low temperatures Sunday morning are expected to be slightly warmer, ranging from the upper 30s to the mid-40s. Temperatures on Sunday are anticipated to be slightly warmer than today due to weak WAA ahead of the low pressure system. Inland areas will reach the low to mid 60s, while the mid to upper 50s are more likely closer to the coast, where increased cloud cover and higher rain chances will persist. Behind the system's associated cold front, a chilly night is expected Sunday night, with low temperatures dropping into the mid to upper 30s to the low 40s.
Light snow and freezing drizzle continue early this morning as an area of low pressure centered over the west metro continues eastward. Most of the snow is confined to north of I-94 with freezing drizzle south, but occasionally there have been bursts of steadier precipitation in the form of snow. Radar and surface obs indicate freezing drizzle continues all the way toward the SD state line, then turns to all snow deeper into the colder air farther west. Winds will increase this morning behind the low in the strong CAA regime.
308 AM EST Sun Jan 12 2025 Cold and dry conditions are expected through much of the week as a series of high pressure centers move over the area. The high moves very little today and tonight, but does move enough for light westerly wind to develop across the mountains and southwesterly winds elsewhere. To the north, a weakening upper low retreats into Canada and eventually gets absorbed into the general flow. As this area of low pressure recedes, it opens the door for another round of Arctic air to spill into the central CONUS. Given the stout high pressure and reinforcing air mass, dry conditions prevail.
1239 AM EST Sun Jan 12 2025 Chilly high pressure will build into the area through early Monday.
1234 AM EST Sun Jan 12 2025 High pressure slowly builds from the west early this morning and then over the waters into tonight.
With snow cover remaining on the ground, some patchy areas of freezing fog may develop overnight. A dry cold front will move through Sunday night and knock temperatures back down to below normal.
107 AM EST Sun Jan 12 2025 Dry weather is expected Sunday under high pressure. A crossing cold front will then bring scattered snow showers to the region for Monday. KEY MESSAGES: - Snow will continue to taper off in the ridges early this morning - Dry and slightly below average temperature Sunday -------------------------------------------------------------------- Light upslope snow continues early this morning across the higher terrain, but additional accumulation will be minimal and showers are likely to end before sunrise as high pressure builds. Area stratocu has largely eroded west of the ridges, and clearing skies have allowed temperatures to plummet where wind is calm.
Temperatures are now broadly in the mid 60s Dew points have fallen back to near 60, down from near 70 prior to the cold front. This cool direction will maintain slightly cooler than normal conditions with overnight lows ranging broadly from the upper 50s to lower 60s. High pressure building eastward into the eastern United States will result in light to gentle northwest to northerly breezes to modestly freshen and shift north to northeasterly through the overnight period. VFR conditions will prevail at the island terminals, at least initially, in wake of a recent cold front.
Updated at 227 AM CST Sun Jan 12 2025 - Much cooler and still breezy on Sunday. (Today and tonight) A weak cold front has made its way south of the FA. Despite the FROPA, temps are still 5 to 10 degrees warmer than they were this same time last night. A few areas across the southern Rolling Plains may see highs reach into the low 50s. Zonal flow will remain overhead through tomorrow morning as the positively tilted upper trough axis remains well to our north, extending westward to southern California.
(Today through Monday) - A weak cold front will move across the region today, with mainly dry conditions forecast. Clear skies and cold temperatures are seen early this morning, with lows just before sunrise expected to be in the low to mid 30s. A weak cold front located in Central Texas will move across the area today. Highs today will vary from the mid and upper 50s north to the low and mid 60s south due to the timing of the front. This will mainly re-enforce the cold air with highs on Monday expected in the low 50s to low 60s areawide.
232 AM CST Sun Jan 12 2025 - A blast of arctic cold air is coming with a cold front's passage tonight.
1224 AM EST Sun Jan 12 2025 Low pressure will pass well south of the area tonight followed by high pressure Sunday into Sunday night.
1020 PM EST Sat Jan 11 2025 Center of high pressure will migrate across the area late tonight thru Sun and offshore during Mon. Cold high pressure will follow, ridging across the area from the central U. High pressure centered across the Tennessee Valley will drift across the area through Sunday. Low temps in the mid to upper 20s Monday night with dry cold front moving across sometime during the night. Unseasonably cool and dry weather continues through midweek with high pressure centered to the west and low level CAA in full swing.
911 PM CST Sat Jan 11 2025 High pressure has already shifted to the east of the area, with winds from the Atchafalaya Basin westward already becoming light southerly.
938 PM MST Sat Jan 11 2025 - Reduced snow totals - Impactful snow, areas blowing snow through Sunday morning over northeastern Wyoming, and the Sturgis foothills - Upslope snow for the favored areas of the northern Black Hills and the Spearfish foothills into Sunday afternoon - Another shot of upslope snow Monday for the northern Black Hills 21Z Analysis shows an upper trough currently crossing the South Dakota side of the forecast area, extending southward from an upper low over northern Manitoba. Areas of light snow and blowing snow are located over parts of northeastern Wyoming, with a few snow showers over the western South Dakota plains, associated with the upper trough crossing the area. There may also be an inch or two of accumulation overnight along the Pine Ridge in southwestern SD.
1046 PM CST Sat Jan 11 2025 - A blast of arctic cold air is coming with a cold front's passage Sunday night.
1216 AM EST Sun Jan 12 2025 (Rest of today through Sunday) Cold front will finish crossing South FL by mid to late afternoon, with scattered showers expected along and ahead of the front and some light drizzle for an hour or so behind the front. With cooler and drier air starting to filter into the area, overnight lows will be chilly ranging from the middle 40s in the lake region, to mid and upper 50s across SE FL. High pressure centered over the Southern Appalachians will be in control on Sunday. Slightly below normal temps are expected with afternoon highs in the lower 70s north of Alligator Alley to middle 70s over the far southern portion of the peninsula.
This active upper level pattern will continue to support the ongoing series of cold fronts pushing into the area, which will keep temperatures below normal for much of the next seven days. After yesterday's cold front, this morning will get off to a cold start with freezing temperatures and frost over parts of the Nature Coast. Before the warm front can progress any farther north, the system will get swept up by a cold front that will move through Monday night, with showers developing ahead of the system Monday and Monday night.
115 AM EST Sun Jan 12 2025 Center of high pressure will migrate across the area late tonight thru Sun and offshore during Mon. Cold high pressure will follow, ridging across the area from the central U. High pressure centered across the Tennessee Valley will drift across the area through Sunday. Low temps in the mid to upper 20s Monday night with dry cold front moving across sometime during the night. Unseasonably cool and dry weather continues through midweek with high pressure centered to the west and low level CAA in full swing.
Areas well south of highway 50 make bottom out in the lower teens, which is not much of an escape from the brutal cold. With the vertical profile remain below freezing, snow is the most likely mode of precipitation should sufficient lift allow the atmosphere to realize any hydrometeors. This snow may stick to roads and sidewalks with temperatures remaining 10-15 degrees F below freezing, so slick conditions cannot be ruled out at this time, especially along I-35 and highway 65.
409 AM MST Sun Jan 12 2025 - Snow showers taper today, but some afternoon orographic showers are expected to produce an additional inch or two of new snow on the high country.
- A weak cold front moves through early this morning, bringing cooler temperatures through Monday.
450 AM CST Sun Jan 12 2025 (Today through Monday) - A weak cold front will move across the region today, with mainly dry conditions forecast. Clear skies and cold temperatures are seen early this morning, with lows just before sunrise expected to be in the low to mid 30s. A weak cold front located in Central Texas will move across the area today. Highs today will vary from the mid and upper 50s north to the low and mid 60s south due to the timing of the front. This will mainly re-enforce the cold air with highs on Monday expected in the low 50s to low 60s areawide.
(Now through Monday) A large positively tilted upper trof stretching from the northern Plains to near the Baja area becomes increasingly elongated during the period and expands into the northeastern states. Highs on Monday will be in the lower to mid 50s.
614 AM EST Sun Jan 12 2025 High pressure will build over the area today then slide east tonight. A weak warm front will lift across the area Monday.
418 AM EST Sun Jan 12 2025 High pressure will move away from the area today as a cold front approaches. The cold front will move through the region tonight into Monday morning. Temperatures will be a few degrees warmer than yesterday. Cold front will push into the region after midnight and pass off to the east of the area Monday morning. This will determine whether there would be light snow or drizzle/freezing drizzle. Meridional flow will be present across the CONUS to start the period Monday night, with a ridge over the western United States and a persistent trough over the east.
540 AM CST Sun Jan 12 2025 - A weak cold front moves through early this morning, bringing cooler temperatures through Monday.
359 AM CST Sun Jan 12 2025 - A quick burst of snow and occasional freezing drizzle will cause limited wintry impacts today in areas north of I-70.
532 AM CST Sun Jan 12 2025 Today and Tonight: Wl start off cold and dry this morning with most of the area below freezing and a PWAT less than a quarter inch. The precipitation will end well before temperatures across our north bottom out near freezing.
- A dry cold front will move through the region today, knocking temperatures back below normal to begin the workweek.
- Lingering flurries/very light freezing drizzle north today with breezy northwest winds gusting 25-30+ mph.
