Fog has expanded into the rest of the Lower Treasure Valley and much of the Upper Weiser River Basin this evening. Some fog erosion is expected mid-day Tuesday, but will return Tuesday night as high pressure strengthens across the area.
1039 PM CST Mon Dec 9 2024 - A strong cold front will move through the area this afternoon and evening bringing much cooler temperatures for Tuesday. - Below freezing temperatures are expected Tuesday night. (This evening through Tuesday) A cold front tracking southward through West Central Texas this afternoon and evening will bring cooler and drier northerly flow across the area through Tuesday. Overnight lows tonight will range from the mid 30s to lower 40s, with the coldest temperatures expected across the Big Country and potentially the typical low-lying areas experiencing temperatures nearing the freezing mark.
1000 PM CST Mon Dec 9 2024 - More snow showers and wind gusts up to 35 mph as another cold front comes through Tuesday afternoon.
1243 AM EST Tue Dec 10 2024 (Rest of today through Tuesday) An area of high pressure over the western Atlantic and mid-level ridging across the Gulf of Mexico will continue to influence conditions over South Florida through the short term period.
957 PM MST Mon Dec 9 2024 - A cold front has moved across the area from north to south brining snow to the northern and central mountains and northern San Juans. In general snow has been light, but at times has increased in intensity with the passage of a cold front from the north. At this point the cold front has reached the southern portion of our CWA. Expected snow totals are still generally falling between 2 to 4 inches with the exception of the highest peaks of the central and northern mountains. With the prorogation of the trough through our area, flow has become more northerly.
- Gusty north winds between 25-35 mph will occur behind a cold front this morning.
1114 PM CST Mon Dec 9 2024 - Light snow showers exit as a low pressure system exits the Northland.
1050 PM CST Mon Dec 9 2024 - More snow showers and wind gusts up to 35 mph as another cold front comes through Tuesday afternoon.
- A cold airmass will move through the area today and bring much cooler temperatures.
However, as another upper disturbance advances into the area overnight into the early morning hours Tuesday, redevelopment of showers is anticipated ahead of the approaching cold front. The main upper trough axis will approach the area tonight, with showers/thunderstorms increasing once again, mainly for areas along and southeast of the Natchez Trace Corridor. The showers/storms will continue mainly over the southeast Tuesday morning, but will begin to shift eastward as a cold front moves across the area through the day. Cooler/drier air will build in behind the boundary Tuesday afternoon. Highs on Tuesday will range from the low 60s across the delta to the mid 70 in the Pine Belt Region.
1106 PM CST Mon Dec 9 2024 - Isolated light rain/snow showers associated with a cold front will continue through the afternoon, primarily across central Minnesota/western Wisconsin.
Another day of dry, warm weather with high pressure situated over the Western Atlantic leading to a light southerly flow.
- Much cooler and windy conditions will prevail today following yesterday's cold frontal passage, with most of the area falling below freezing tonight.
With dewpoints in the upper 60s, there isn't really much lower to fall to even if we had perfectly calm winds to radiate out resulting in forecast lows in the lower 70s.
A cold front will move across the Midsouth today resulting in cooler and drier conditions for the next few days.
520 AM CST Tue Dec 10 2024 - A cold airmass will move through the area today and bring much cooler temperatures. - Below freezing temperatures are expected late tonight into Wednesday morning (Today and tonight) Early this morning, a cold front was moving quickly into south Texas. In its wake, a 1030mb high pressure center driving this Canadian-based airmass should move southeastward into west central Texas through the day. Overnight, skies should clear out and the high pressure center should reach the Big Bend region which should allow winds to decrease to around 5 to 10 MPH. All indications are that temperatures could easily fall into the upper 20s by Wednesday morning with some low-lying areas potentially falling to the low 20s.
329 AM CST Tue Dec 10 2024 - Cooler conditions will occur today and Wednesday with highs in the middle/upper 30s to lower 40s.
In wake of the front, expect northwesterly winds to push in much cooler and drier air into the region. Highs today will be 10 to 15 degrees cooler than yesterday, ranging from the lower 50s in our northern zones, to the mid 60s across portions of Deep East Texas and adjacent Central Louisiana. Northwesterly winds should diminish some, but these winds will continue to push cooler and drier air into the region. Freezing temps will be possible in some locations by Wed morning, with lows ranging from the upper 20s to mid 30s. (Wednesday Night through Tuesday) High pressure will settle over the region by Wednesday night. This should allow for good radiational cooling and another night of freezing temps, as lows will range from the upper 20s to lower 30s.
513 AM CST Tue Dec 10 2024 - Cooler conditions will occur today and Wednesday with highs in the middle/upper 30s to lower 40s.
602 AM EST Tue Dec 10 2024 (Today through Wednesday) Warm and pleasant weather across South Florida today as high pressure over the western Atlantic and mid-level ridging over the Caribbean remain in control. Highs will be in the low to mid 80s, with tonight's lows in the mid 60s to low 70s. This will send a cold front across the FL Peninsula, which will move into South Florida from late afternoon through the evening and overnight hours. High temperatures will again reach the low to mid 80s. Winds will become strong out of the north-northeast behind the front, and begin to usher in a cooler, dry, and breezy period of weather.
534 AM EST Tue Dec 10 2024 Rain chances will increase today and tonight with the approach and passage of a cold front.
742 AM CST Tue Dec 10 2024 A cold front will move across the Midsouth today resulting in cooler and drier conditions for the next few days.
The dry cold front has swept through all of northern Arizona, with a very dry (dewpoints 0 to -10F) and cold air mass filtering in from the north.
514 AM CST Tue Dec 10 2024 - A cold airmass will move through the area today and bring much cooler temperatures. - Below freezing temperatures are expected late tonight into Wednesday morning (Today and tonight) Early this morning, a cold front was moving quickly into south Texas. In its wake, a 1030mb high pressure center driving this Canadian-based airmass should move southeastward into west central Texas through the day. Overnight, skies should clear out and the high pressure center should reach the Big Bend region which should allow winds to decrease to around 5 to 10 MPH. All indications are that temperatures could easily fall into the upper 20s by Wednesday morning with some low-lying areas potentially falling to the low 20s.

Temperatures will fall a bit more with most spots ending up in the low to mid 30s by sunrise.
Continue to use caution during your commute in these locations, leaving extra distance between vehicles and using low-beam headlights! Today, high temperatures are forecast to reach the upper 60s despite overcast clouds due to southerly flow ahead of a cold front that is forecast to move through the area. This front is ahead of an upper level trough sweeping eastward through the southern Plains. Latest CAMs are in agreement that the highest chances of rain will be limited primarily east of I-65 as showers move in from the southwest.
- Gradual warm up with windy conditions across the higher mountains and eastern slopes at times. As the upper-level trough slowly moves off to the east, northerly flow aloft will keep us cool and breezy throughout the day on Tuesday. Meanwhile, areas closer to the Kansas border will be in the low-40s.
Another day of dry, warm weather with high pressure situated over the Western Atlantic leading to a light southerly flow. Wednesday the pattern begins to shift as a cold front moves over the state. Behind the front cooler temperatures will once again descend bringing the return of the 30s and 40s for lows. These cooler temperatures do not stick around long this time and by the weekend we return to a little above normal.
(Today through Wednesday) A cold front is expected to reach the northern ranchlands around daybreak this morning and should move through the Rio Grande Valley and off the lower Texas coast early this afternoon. High temperatures today are expected to reach the mid to upper 60s across the northern ranchlands to the lower 70s across the Rio Grande Valley. Overnight lows should fall into the upper 30s to the lower 40s across the northern ranchlands, the mid 40s across the Rio Grande Valley and the lower 50s along the coast. Breezy north winds will support feel like temperatures near freezing across the northern ranchlands and the upper 30s to around 40 for the Rio Grande Valley. High pressure settles across the region on Wednesday with below normal temperatures. Highs on Wednesday will be in the low to mid 60s.
Clear and cold early this morning with temperatures in the low teens or single digits.
A cold front moving south through the region today will bring snow mainly to the SW part of the forecast area where a few locations mainly near Zortman, over western Garfield County and the Big Sheep Mountains of western Prairie County could see up to 2 inches. The probability of one inch or more of snow today is 50 to 80 percent in these areas and probability of 2 inches or more snow is up to 40 percent in the higher elevations of Garfield County and higher elevations of the Little Rockies of SW Philips County and less than 5 percent elsewhere. The cold front will bring lows below zero north and east of Glasgow and Glendive tonight.
Morning low temperatures will be in the low to mid 30s, so areas of patchy frost will be possible on grassy areas. Today and most of the day Wednesday will be the last dry and mostly clear days, as upper level ridging continues to be in control of our synoptic pattern.
Weak high pressure will briefly build into the region today and Wednesday which will result in low impact weather.
540 AM CST Tue Dec 10 2024 (Today through Wednesday) The cold front has moved south of San Antonio and will exit south of the forecast area pre-dawn. Much cooler conditions are forecast today, with high temperatures ranging from only the mid 50s across the Hill Country and Central Texas to low to mid 60s south of U. Some pockets of freezing temperatures are also likely across Williamson County, east of the I-35 corridor, and near the Rio Grande. After the cold morning start Wednesday, high temperatures in the afternoon are foreast to make it into the low to mid 60s for most areas, under sunny skies.
Additional accumulations of 3 to 8 inches with locally higher amounts in the higher elevations. - Near-advisory level wind gusts expected today as another cold front pushes through the region.
The cold front can be seen very well from near SHV to just west of Victoria TX at 230a.
- Warmer weather returns as we close out the week as a more zonal patter takes hold and afternoon highs return to the 50s and 60s.
High pressure through Wednesday with dry but cool conditions.
601 AM CST Tue Dec 10 2024 - A strong cold front will move through the state today resulting in gusty northwest winds and temperatures dropping during the day, especially in the northern half of the state.
- A cold airmass will move through the area today and bring much cooler temperatures. - Below freezing temperatures are expected late tonight into Wednesday morning (Today and tonight) Early this morning, a cold front was moving quickly into south Texas. In its wake, a 1030mb high pressure center driving this Canadian-based airmass should move southeastward into west central Texas through the day. Overnight, skies should clear out and the high pressure center should reach the Big Bend region which should allow winds to decrease to around 5 to 10 MPH. All indications are that temperatures could easily fall into the upper 20s by Wednesday morning with some low-lying areas potentially falling to the low 20s.
1150 AM CST Tue Dec 10 2024 (Today through Wednesday Night) Cold front is in the process of moving across the area and should be off the coast by around 6am. Modestly cooler air will filter into the region this morning, but look for stronger CAA to commence later this afternoon with a secondary push of even drier air making its way way across the region. Much colder wx is anticipated overnight as high pressure makes its way south toward the Big Bend and Rio Grande tonight. High pressure will drift eastward across the area Wednesday and Wednesday night.
The primary feature of interest is a developing cold front currently located just off the Texas coastline that will extend across the eastern United States into the Great Lakes. A deep arctic air mass will surge south into the northern Plains over the next 24 hours as an upper-level trough sharpens over the eastern United States.
Satellite image shows fog and freezing fog in the Umpqua Basin. LIFR ceilings remain in the Umpqua Valley and freezing fog continues in the Rogue Valley this morning.
(This evening through Wednesday night) An amplifying upper level trough extends from the upper Mississippi River Valley down to central Texas. This trough will sweep across the northern Gulf Coast now through Wednesday. In the near-term, showers and isolated storms have developed locally along a shear axis between that trough and upper ridge centered near Cuba. Some help in eastward progression will come as the actual cold front, roughly along a line from Jackson MS to Natchez to Lake Charles, moves into the CWA.
12Z geo-potential height fields aloft indicate upper trough is sharpening over the Plains, down into west TX. At the surface, cold front is dropping southeast into the Lower MS River Valley. With the sharpening of the upper trof, bulk shear parameters have responded and increased with 0-6km west to southwest vector magnitudes 40-60 kts. Cold front sinks southeast into the western zones this evening, crossing the I-65 corridor by around midnight and sweeping rapidly east through the area before daybreak Wednesday. Much drier and cooler (highs mostly in the mid 50s much of the area) for Wednesday along with a brisk northwest wind gusting to between 20 and 30 mph. Overnight lows Wednesday night expected to be colder over the northern zones at around the freezing mark to 37 to 42 closer to the coast.
These gradients are expected to collapse later today and tonight as a s/wv ridge moves into the region.
Generally a localized dusting of snow, best potential for an inch or more near the Pine Ridge and downwind into the central sandhills.
High pressure continues to build over the region this afternoon and will continue doing so through early Wed AM. The ridge will get suppressed during the day on Wednesday ahead of an approaching system and clouds will begin to increase over the course of the day, accordingly.
Tonight through Wednesday: A cold front will move through the region this evening. Expect much cooler and drier conditions for the area on Wednesday as daytime temps only reach into the mid 50s.
1015 AM EST Tue Dec 10 2024 Most of the low clouds and fog have burned out.
112 PM CST Tue Dec 10 2024 (Rest of Today) A slow moving pre-frontal trough axis continues to drape itself from eastern Kentucky SSW through Centreville, TN SW to just near Vicksburg, MS. A warm front extends east from this pre- frontal trough axis through central TN into eastern North Carolina. A second moisture convergence boundary extends SE from this prefrontal trough axis near Centreville, TN into SW Alabama.
358 PM EST Tue Dec 10 2024 Several chances for light snow tonight and Wednesday as low pressure moves east of the region.
- Warmer weather returns as we close out the week with afternoon highs in the 50s and 60s.
1129 AM CST Tue Dec 10 2024 - Cooler conditions will occur today and Wednesday with highs in the middle/upper 30s to lower 40s.
1149 AM CST Tue Dec 10 2024 A cold front will move across the Midsouth today resulting in cooler and drier conditions for the next few days.
(Rest of Today) A slow moving pre-frontal trough axis continues to drape itself from eastern Kentucky SSW through Centreville, TN SW to just near Vicksburg, MS. A warm front extends east from this pre- frontal trough axis through central TN into eastern North Carolina. A second moisture convergence boundary extends SE from this prefrontal trough axis near Centreville, TN into SW Alabama.
(Rest of today through Wednesday) A cold front has been pushing through Middle TN this morning bringing showers and overcast skies to the entire area. This could allow for just enough instability to enhance showers over our far eastern counties early this afternoon, but the cold front will gradually push east and sweep colder drier air into the area pushing those showers off the Plateau by late afternoon. The upper trough axis will pass by on Wednesday, sweeping the last of the moisture off to our east. High temperatures will be several degrees cooler in the afternoon, then much cooler, in the 20s, Wednesday night.
(Rest of today through Wednesday) Warm and pleasant weather across South Florida today as high pressure over the western Atlantic and mid-level ridging over the Caribbean remain in control along with abundantly dry air in the mid- levels. Highs will be in the low to mid 80s, with tonight's lows in the mid 60s to low 70s. On Wednesday, a deep mid-level trough will swing across the Southeast US as it wraps around a closed low over the Great Lakes region. This will send an associated cold front across the FL Peninsula, which will move into South Florida from late afternoon through the evening and overnight hours. High temperatures will again reach the low to mid 80s. Winds will become strong out of the north-northeast behind the front and begin to usher in a cooler, dry, and breezy period of weather.
(Tonight through Wednesday night) A cold front has moved through Deep South Texas which will bring windy conditions and colder temperatures to the region. With the breezy conditions, some areas of the northern Ranchlands will have feels like temperatures near the freezing mark, with feels like temperatures reaching right around 40 degrees in the Valley. On Wednesday, temperatures will reach the mid 60s for afternoon highs and overnight lows falling into the low 40s across the Ranchlands to mid to upper 40s in the Valley.
This will result in temperatures dropping off rapidly into the lower to mid 30s and even some isolated upper 20s in far northern zones. The longwave trough will continue to pivot east of the region on Wednesday with abundant sunshine returning. The pressure gradient will remain elevated as a strong high pressure ridge at the sfc builds closer to the region.
Satellite image shows fog and freezing fog in the Umpqua Basin. Areas of LIFR ceilings and freezing fog remain in portions of the Umpqua Valley, lower Rogue Valley and the Illinois Valley currently.
946 AM CST Tue Dec 10 2024 - A strong cold front will move through the state today resulting in gusty northwest winds and temperatures dropping during the day, especially in the northern half of the state.
Synoptically, ridge of high pressure has been sliding south and east as deep Canadian upper level trough stretching across the Midwest today and into the Southeast/East Coast on Wednesday. The trough quickly exists the area through the afternoon with cool/dry air, and gusty northerly winds pushing behind it. Afternoon highs should will range from the low 70s to around 80.
- A cold airmass will move through the area today and bring much cooler temperatures overnight tonight into Wednesday morning. - Below freezing temperatures are expected late tonight into Wednesday morning. Given the drier conditions and higher potential for radiational cooling given the lack of cloud cover, overnight lows are expected to plummet into the lower 20s to lower 30s.
1156 AM CST Tue Dec 10 2024 - A cold airmass will move through the area today and bring much cooler temperatures. - Below freezing temperatures are expected late tonight into Wednesday morning (Today and tonight) Early this morning, a cold front was moving quickly into south Texas. In its wake, a 1030mb high pressure center driving this Canadian-based airmass should move southeastward into west central Texas through the day. Overnight, skies should clear out and the high pressure center should reach the Big Bend region which should allow winds to decrease to around 5 to 10 MPH. All indications are that temperatures could easily fall into the upper 20s by Wednesday morning with some low-lying areas potentially falling to the low 20s.
pdf Warm south-southwesterly flow continues with the area between departing ridging into the Atlantic and a large upper trough swinging into the SE US. Meanwhile, a cold front over LA/MS/AL will shift eastward toward GA tonight and likely enter our far inland SE GA zones by sunrise. The main limiting factors for stronger convection will be minimal instability and warmer temps aloft. However, this high shear, low CAPE environment could produce a couple of strong storms capable of producing gusty winds and a weak, brief tornado.
521 PM CST Tue Dec 10 2024 - Warmer weather returns as we close out the week with afternoon highs in the 50s and 60s.
Trough continues to shift through the Texas Panhandle into Oklahoma through today and tomorrow. We are currently situated on the back edge of the trough with northwesterly flow aloft. Satellite continues to show upper level clouds shifting through the region this afternoon on the back edge of the upper level trough moving through Texas and Oklahoma. Early on the snow will be mixing in with rain as temperatures in the early part of the evening remain at or above freezing. Precipitation chances help bring temperatures down, while little to no precipitation allows temperatures to reach into the lower 50s.
The cold front has cleared the forecast area, and a broken stratus deck along the frontal slope now trails across much of the area. As the front continues eastward through the night, the lower clouds will quickly erode. /DL/ Tonight through Wednesday: A cold front will move through the region this evening. Expect much cooler and drier conditions for the area on Wednesday as daytime temps only reach into the mid 50s.
- Many locations will fall below freezing tonight with a gradual warm-up expected through the end of the work week.
513 PM CST Tue Dec 10 2024 (Tonight through Wednesday night) A cold front has moved through Deep South Texas which will bring windy conditions and colder temperatures to the region. With the breezy conditions, some areas of the northern Ranchlands will have feels like temperatures near the freezing mark, with feels like temperatures reaching right around 40 degrees in the Valley. On Wednesday, temperatures will reach the mid 60s for afternoon highs and overnight lows falling into the low 40s across the Ranchlands to mid to upper 40s in the Valley.
High pressure weakens over the region as the next offshore system slowly approaches.
527 PM CST Tue Dec 10 2024 Tonight through Wednesday: A cold front will move through the region this evening. Expect much cooler and drier conditions for the area on Wednesday as daytime temps only reach into the mid 50s.
