- Snow showers and flurries may produce a dusting of snow across northern Nebraska, especially near the Pine Ridge. However a strong cold front will enter Nebraska from the northwest early this morning, then push through central Nebraska before moving off to our east by early this afternoon. A light dusting of snow is possible mainly along and north of highway 20 with the Pine Ridge perhaps seeing accumulations of around half an inch or so. Ensemble guidance is in good agreement in advertising a progressive, fairly low amplitude pattern across the lower 48 with a cold upper low over Canada having trouble making a sustained push down into the US.
(Today through Saturday) The next front is on the way pushing the high pressure to the east and turning the winds southerly. mid to upper 40s overnight and a bit warmer on Saturday.
520 AM CST Fri Dec 2 2022 (Today through Saturday Night ) To begin the period, high pressure has shifted east of the state allowing for a trough to dive into to the area from the northwest. This will bring a cold front into the state late Friday into Saturday. Expect scattered showers through the day today as southerly flow around the high returns moisture into the state. The cold front is expected to move into the state early Saturday continuing some of those on and off showers.
403 AM CST Fri Dec 2 2022 (Issued 403 AM CST Fri Dec 2 2022) Today through Saturday: Low pressure tracking from SD to Lake Superior is responsible for the breezy southerly winds across southern WI today. The associated cold front will cross southern WI this evening, clearing the lakeshore right around midnight.
Mid-level high pressure builds over the central United States bringing warmer weather to Deep South Texas for the weekend. The rest of Saturday will be pleasant with mostly sunny skies and highs in the lower 80s.
635 AM EST Fri Dec 2 2022 Cooler and dry conditions are expected today. Saturday is the warmer of the two weekend days ahead of the next cold front. High pressure over the region with fair and cool conditions in store for today. Given the recent moist bias, went with the warmer solution. High pressure will still be dominant however and conditions will calm shortly after sunset. Cold front will be just off to the west of Appalachians Saturday morning, with the front then moving across the cwa Saturday night.
Cold and dry air have infiltrated most of the region in the wake of the cold front that moved through yesterday. Widespread freezing and frost will be prevalent in Northwest California.
527 AM CST Fri Dec 2 2022 (Today through Saturday) The next front is on the way pushing the high pressure to the east and turning the winds southerly. mid to upper 40s overnight and a bit warmer on Saturday.
As the trough moves rapidly eastward winds are expected to diminish through the day with a bit cooler temperatures and partly to mostly cloudy skies.
536 AM CST Fri Dec 2 2022 Today through tonight: A warm advection pattern has developed quickly and this will support increasing clouds and chances for showers, especially later tonight, ahead of an approaching cold front. Temperatures will be considerably milder with southerly wind picking up as a warm front pushes through. /EC/ Saturday: Scattered showers will continue ahead of a weak cold front pushing southward across the region through the day.
Moving in quickly behind this high will be the next front that will stall and dissipate across northern Florida over the weekend.
(This evening through Saturday night) West winds will decrease by sunset as the low level mixing decreases and the upper level short wave moves through the northern Plains. A cold front will push through the Panhandles and winds should increase again into the 15 to 25 mph range with higher gusts. Highs on Saturday are expected to be in the mid 40's to the lower 50's after lows in the 20's and lower 30's tonight. However, a cold front will move south across the Panhandles this evening.
This has allowed temperatures to warm into the lower to mid 70s, which is a good 10 to 15 degrees above normal for this time of year. Changes are on the way however as our next cold front moves across the area tonight. It will much cooler tomorrow, with highs mainly in the 50s.
The main upper trough is entering the Northern Plains, and will quickly move off into the Great Lakes overnight. The surface cold front has already passed through our counties, but there is good synoptic lift and some 700mb frontogenesis behind the surface front across our central counties. The lower visibility is short lived, but enough to keep winter impacts going from at least the Red River Valley eastward.
/JNE/ Today through tonight: A warm advection pattern has developed quickly and this will support increasing clouds and chances for showers, especially later tonight, ahead of an approaching cold front. Temperatures will be considerably milder with southerly wind picking up as a warm front pushes through. /EC/ Saturday: Scattered showers will continue ahead of a weak cold front pushing southward across the region through the day.

Breezy and cooler conditions are expected through the weekend, with chances for rain showers over central and eastern Arizona. A longwave trough begins to eject off the Pacific to Northern California on Saturday. While simultaneously, high pressure builds over Texas and the western Gulf of Mexico.
250 PM CST Fri Dec 2 2022 Today and Tomorrow: A slowly moving cold front will serve as the main focus in the short term period. Low temperatures tonight will range from the upper 50s to the mid 60s which is warmer than what we've experienced these last few nights. Most of the shower activity tomorrow will be light however, a few rumbles of thunder can't be ruled out especially across the south where it will be a bit warmer and better instability (what little instability that will be there).
Near normal high temperatures are expected with highs in the low 80s, while low temperatures will be a few degrees above normal, ranging from the low 60s near the lake to around 70 along the east coast. An area of low pressure passing through the northeast will continue to push the weakening high further out to sea for Saturday, however it will remain our primary synoptic influence resulting in another day of breezy easterly flow. Given the influence of the mid-lvl ridge over the GOM and a dry (PWATs sub 1 inch) airmass in place, rain chances should be negligible. Temperatures will warm a degree or two relative to Friday, although with dewpoints mixing out into the lower 60s it should feel less humid than it did earlier in this week.
Temperatures locally were in the lower to upper 30s. Strong W to NW winds of 20 to 30 mph will develop behind a cold front and gust up to 50 mph. Temperatures will fall into the teens with wind chills in the single digits above and below zero! Today Mild and windy weather is expected today ahead of a strong cold front that will arrive tonight. Strong low-level warm air advection will push highs into the lower to upper 50s, warmest south of I-80. Tonight A sharp cold front will plow through the region, reaching the western counties between 5 - 7 PM, and eastern sections between 8 - 10 PM.
908 AM CST Fri Dec 2 2022 (Issued 908 AM CST Fri Dec 2 2022) Winds will become increasingly gusty through the day today, as southwest flow strengthens ahead of a cold front. We'll likely see a short lull in the winds this evening as the pressure gradient becomes baggy with the approach of the trough. Boxell (Issued 403 AM CST Fri Dec 2 2022) Today through Saturday: Low pressure tracking from SD to Lake Superior is responsible for the breezy southerly winds across southern WI today. The associated cold front will cross southern WI this evening, clearing the lakeshore right around midnight.
Things will remain on the chilly side however with highs struggling to reach freezing today and again for Saturday.
Strong low level flow (50-55 kts @ 925 mb and 60-65 kts @ 850 mb) will remain in place ahead of a strong cold front sweeping in later tonight.
Southeasterly surface winds transition to southwesterly in the lower-levels providing mild temperatures and warm advection with highs expected to reach the lower 60s north to near 70F south. Moisture rises overnight ahead of a cold front associated with a low- level trough centered over Ontario.
1143 AM CST Fri Dec 2 2022 (Today through Saturday Night ) To begin the period, high pressure has shifted east of the state allowing for a trough to dive into to the area from the northwest. This will bring a cold front into the state late Friday into Saturday. Expect scattered showers through the day today as southerly flow around the high returns moisture into the state. The cold front is expected to move into the state early Saturday continuing some of those on and off showers.
A weak ridge will continue to build inland through Saturday as a deep Pacific low pressure system drops along the west coast.
(Through Tonight) Strong high pressure will be northeast of the region through Tonight, with a weakening inverted trough over the coastal waters.
1211 PM EST Fri Dec 2 2022 Warmer today with increased clouds and winds today into tomorrow.
The KBYX radar detects widely scattered showers across the distant Straits of Florida co-located with the remnants of a weak cold front.
Behind the trough, heights are already beginning to rise. With short wave ridging, temperatures will be moderating somewhat, with highs generally into the low to mid 30s for highs.
A few showers will remain possible, mainly in the higher terrain areas of SE OK/NW AR.
On Saturday, an upper level trough will dig in over the Great Lakes area.
(This evening through Saturday) A cold front will enter northwest Oklahoma around 6pm this evening, then quickly sweep across the forecast area, reaching the Red River by midnight. Forecast grids have a blend of short term guidance which seems to better reflect the higher peak wind potential over a fairly focused timeframe behind the front. Colder air behind the front will result in lows below freezing across the northern third to half of Oklahoma Saturday morning (upper 30s across southern portions of the forecast area), and afternoon highs in the 40s and lower 50s with some scattered high level clouds.
Colder temperatures are expected for most of the next workweek with several days of overnight lows below freezing.

After the low level CAA sequence ends tonight, some low level WAA is still a probable scenario for Saturday into Saturday night.
(This evening through Saturday) After the mildest temps of the week, a return to reality arrives tonight thanks to a robust cold front. Following a few hours of gusty NE winds with FROPA overnight, high pressure will wedge south through the morning and deliver a decent cold dome that looks to cap most areas off in the 40s for highs tomorrow under partly sunny skies. As chilly surface ridging slowly pulls away Saturday afternoon, modest isentropic ascent will materialize from 310-315K underneath a plume of mid/high-level subtropical moisture in WSW flow.
That type of mixing is possible near and behind the cold front. Rain will mix with and change to snow with the passage of the cold front as the entire sounding drops rapidly below freezing. This area may see some light accumulations after the passage of the cold front, on the order of a half inch to an inch at best.
Strong ridge to the north will maintain a breezy onshore flow across the area today, with speeds up to 15 to 20 mph, especially along the coast.
