Snowfall rates around an inch per hour have been observed over the past two hours in Grand Rapids where the higher radar returns have tracked through. Temperatures will also be falling into the low 20s overnight causing any wet, untreated surfaces to freeze.
339 AM EST Thu Jan 2 2025 High pressure will prevail through the weekend.
(Today and tonight) Zonal flow is expected over the region today, as weak upper level high pressure holds over southern CA and upper level disturbance advances towards the PacNW.
A warm front will lift north through the area this morning. If anything, a few of the models like the HRRR are showing some patchy freezing drizzle falling across portions of the upper Snake Plain tonight into Friday morning.
A brief lull in weather today as slight ridging builds across the southwestern U. Near record warm temperatures expected to continue Friday with highs in the 40s to 50s but by Friday afternoon, another round of weather from a low pressure system begins making its way over Nevada from the west, bringing in higher chances (up to 50-75%) of some light mix of precipitation across northern Nevada and may extend towards parts of central Nevada (20-40% chance). The weather system will also bring in much cooler air, bringing overnight lows down but remain 10+ degrees above normal in the 20s.
905 AM EST Thu Jan 2 2025 High pressure will extend into the region through early Friday. An Arctic cold front will move through the area Friday afternoon and evening, ushering in much colder air for the weekend.
335 AM CST Thu Jan 2 2025 - Dense fog possible this morning north of a cold front across parts of central and north central Nebraska.
Temperatures today will be right around average, but Friday, some cooler air moves in and highs will be 5-10 degrees below average. When the period opens, a large upper level trof over the Rockies is causing the upper flow to be split. The deformation zone/mid and upper level WAA-forcing of this upper low is extending over into South Dakota (mainly the western half of the state).
239 AM PST Thu Jan 2 2025 Fair and warmer weather will prevail today under a ridge of high pressure and weak offshore flow.
Daytime mixing should just barely tap some of the very dry air aloft and dewpoints should fall into the lower 20s with minimum relative humidity reaching 29-34 percent. Highs are still expected to reach the lower 50s (6-7 degrees below normal) with light northwesterly winds. Basically in a longwave upper trof pattern this period with the upper trof axis nearly overhead. Cold surge thru midday as high pressure centered over southern Mississippi Rvr Valley slides to the SE States today, suppressing southward during tonight as a Leeside trof off the Appalachians develops. Rather cloudless sky today with increasing cirrus this evening with possibly additional mid level clouds overnight, all well ahead of the next cold front and embedded mid level s/w trofs or vorticies. Maxes today around 50 or the lower 50s.
Broad upper-level troughing over the CONUS today will transition to more of a positive PNA pattern with ridging amplifying over the Inter-Mountain West by tonight and flow becoming northwesterly aloft. This will send a reinforcing cold front into our region as we head into tomorrow.
We're in a brief lull from precipitation at the moment, though more rain is expected to start up in Shasta County late in the morning, and will spread southward to the rest of interior NorCal overnight into Friday as a trough moves inland.
Updated at 334 AM CST Thu Jan 2 2025 - Much warmer today and staying well above normal into the weekend. The shift in wind directions, as well as upper level ridging moving into the area, will bring temperatures back above normal into the 60s to low 70s. Lows for tonight respond to the warmer wind direction and also end up above normal with many spots in the 30s to low 40s. The northern Permian Basin and portions of SE NM still dip into the low 30s.

and Florida with much cooler drier air advecting across the region under partly cloudy skies. Although temperatures it will feel much cooler than the past several days, highs will be near climatological normals. A secondary cold front will push down the Florida peninsula on Friday with a reinforcing shot of cool dry air.
At the surface, temps have fallen into the low to mid 30 for most. We will warm up nicely today with highs settling back into the low to mid 50s. With that said, we will still in the low to mid 30s. Highs on Friday warm back into the low to mid 50s ahead of our next cold front. This cold front/secondary surge of high pressure will bring much colder air to Central Alabama as we head into the weekend.
520 AM CST Thu Jan 2 2025 Updated at 512 AM CST Thu Jan 2 2025 - Dry cold front moves through the area today into tonight.
The cool pattern will continue as a reinforcing cold front sweeps through the area tomorrow.

WEATHER PATTERN OVERVIEW: High pressure will keep most of NE Montana dry today.
557 AM EST Thu Jan 2 2025 A cold front will move southeast across the region tonight into Friday, bringing some light accumulating snow.
Currently - A high cell that consolidated over the southeastern United States has driven a weak cold front through the Keys. Dew points have fallen over 5 points and is now in the lower 60s. This new high will thrust a stronger cold front down across the area.
605 AM EST Thu Jan 2 2025 (Today through Friday) Following the New Year's frontal passage, today's synoptic pattern will remain stable and heavily influenced by the body of high pressure sitting across the southeastern CONUS. However, a significant change is initiated on Friday as several synoptic events introduce cooler air as we move into Friday night and the upcoming weekend. At the mid-levels, the east coast trough axis deepens and moves further into the western Atlantic. Conditions are expected to remain dry with this cold front due to low precipitable water values. However, with this frontal passage, temperatures will begin on a rapid cooling trend Friday night as winds veer northwesterly bringing cooler air.
924 AM EST Thu Jan 2 2025 High pressure will prevail through the weekend.
642 AM EST Thu Jan 2 2025 High pressure will extend into the region through early Friday. An Arctic cold front will move through the area Friday afternoon and evening, ushering in much colder air for the weekend.
The higher elevations could see peak gusts reaching 40-50mph around 19Z and then should start to weaken throughout the late afternoon/evening period. Latest forecasted snow amounts indicate 1 to 3 inches of snow for the higher elevations of Lake and Chaffee counties, though some isolated higher amounts are possible. The lower southeast mountains , the lower eastern slopes of the eastern mts, are expected to hover in the upper 20s. A ridge of high pressure will push eastward across the region throughout the day. Looking at temperatures, most areas will warm to above seasonal values for early January given the ridge and weak downsloping winds. Given this, the cooler temperatures are expected to push westward across portions of the eastern plains, with the warm downsloping winds maintaining control generally along and west of the I-25 corridor and Raton Mesa area.
Overall, through tomorrow night the weather pattern stays pretty constant with the wrapped up low pressure system in southeastern Canada only gradually retrograding towards Hudson Bay. The bulk of the cooling aloft has already occurred, but low level thermal profiles due look to modify a bit towards tomorrow evening behind a subtle wind shift/trough axis. On the synoptic scale the North Country and Vermont will remain entrenched in upper level troughing through the weekend with seasonably cold temperatures and partly to mostly cloudy skies expected.
ARS Dry and cooler weather conditions will persist for the remainder of the week. Confidence has increased for freezing rain to occur in areas along the Tennessee and Kentucky border as well as the Arkansas and Missouri border.
Still looking for a dry cold front to pass late today, early Friday. Broad upper-level troughing over the CONUS today will transition to more of a positive PNA pattern with ridging amplifying over the Inter-Mountain West by tonight and flow becoming northwesterly aloft. This will send a reinforcing cold front into our region as we head into tomorrow.
1135 AM CST Thu Jan 2 2025 - Quiet weather and warmer tomorrow.
Temperature observations are currently trending approximately 5 to 10 degrees warmer than this time yesterday, valid at 1230 PM PST with 50s and 60s in the Valley and foothills, and 40s to 50s in the mountains.
All has remained quiet this afternoon behind the recent cold front. Temperatures continued to rise a few more degrees and have reached into the mid 70s with dew points in the lower to mid 60s. That being said, the active weather will be due to a series of cold front passages. But we will see much cooler weather spill in across the Florida Keys.
1133 AM CST Thu Jan 2 2025 Warmer days expected for the rest of this week.
Snowfall totals by noon today are expected to be 1 to 3 inches, with the highest amounts expected in west-central Iowa.
A warm front will lift northward across the area today. With the warm front lifting north, expect widespread lower ceilings and visibilities with higher terrain obscuration. Freezing levels will rise above 8000-9000 ft on Thursday. Several of the high res guidance that shows radar reflectivity suggest precip will be light to occasionally moderate through this afternoon. A warm front will bring mainly light to brief periods of moderate precipitation into this evening. A cold front will push into the area late tonight into Friday morning with snow levels lowering some. The higher ridges east of the Cascades could experience moderate to occasionally strong southwest winds,. A warm front will move northward through the area today.
Another round of snow moves into western WY early Friday morning ahead of a potent trough thats digging across the PACNW. The current forecast is for 4 to 8 inches of snow across the higher elevations of the Tetons and Gros Ventre Ranges as well as the higher elevations of YNP.
Conditions are expected to remain dry with this cold front due to low precipitable water values. However, temperatures will begin on a rapid cooling trend Friday night behind the front as winds veer northwesterly bringing cooler air.

Coastal areas could see gusts up to 20-30 mph with the higher terrain seeing up to 40 mph ahead of and along the frontal passage.
1125 AM CST Thu Jan 2 2025 Updated at 1120 AM CST Thu Jan 2 2025 - Much warmer today and staying well above normal into the weekend. The shift in wind directions, as well as upper level ridging moving into the area, will bring temperatures back above normal into the 60s to low 70s. Lows for tonight respond to the warmer wind direction and also end up above normal with many spots in the 30s to low 40s. The northern Permian Basin and portions of SE NM still dip into the low 30s.

Across the lower deserts of South Central Arizona, highs on Friday may approach 80 degrees, near the record in Phoenix for the date. Over the weekend, a weather system will pass the region to the north, ushering in cooler yet still slightly above normal temperatures.
1007 AM CST Thu Jan 2 2025 Updated at 1004 AM CST Thu Jan 2 2025 - Dry cold front moves through the area today into tonight.
Light accumulations are expected through the valleys, while the high terrain continues to see several more inches of snowfall through the overnight. Gusts of around 30-35 mph are likely through midday, and then gradually ease through the afternoon as the low pressure across Atlantic Canada slowly moves further away. Otherwise it looks rather quiet as the waves generated on the downstream side of the west coast ridge stay S of the large trough, whose center sits over the the NE CONUS and E Canada. See nothing more than a few SHSN in the mtns at times as weak waves generate near the closed low center, bit otherwise it looks dry.
400 PM EST Thu Jan 2 2025 Low pressure will slowly drift northward in the Maritimes through tonight.
High pressure has settled in over the region behind the last cold front that moved across the area. With the high pressure centered just to our northwest, light north-northeasterly winds have been seen at the surface. The lower and mid levels remain dry, with more moisture located in the upper levels. An upper level short wave will pass to the north of the forecast area tomorrow, dragging a rather dry cold front across the state on Friday night.
215 PM CST Thu Jan 2 2025 The short term begins with calm and dry conditions as a dry cold front moves across the state tonight.
The Keys are enjoying a pleasant post cold frontal passage this morning. Temperatures are warming nicely into the lower 70s with dewpoints in the lower 60s. A reinforcing cold front is expected heading into this weekend.
1150 AM CST Thu Jan 2 2025 - Temperatures will begin to trend cooler into the weekend with overnight lows on either side of zero from Friday night onwards.
(Through Friday) Seasonably cool high pressure will remain in place across the Deep South overnight with a broad trough in place over the eastern half of the CONUS. Expect another chilly night with temperatures falling into the lower to mid 30s. A bit of moderation is expected on Friday as a dry reinforcing front crosses the area during the afternoon, with temperatures reaching the lower to mid 60s.
A longwave trough remains across eastern North America. I've blended NBM and GFS MOS for lows yielding upper 20s for most areas -- a little warmer on the beaches and perhaps approaching 20 degrees over the peat soils of Holly Shelter and Angola Bay gamelands. A potent upper level disturbance arriving Friday evening will help drive a cold front toward the eastern Carolinas. Deep cyclonic flow will usher through yet another cold front across the area late Friday and much like some of the previous fronts it will be dry at least for our area.
1120 AM CST Thu Jan 2 2025 Updated at 1111 AM CST Thu Jan 2 2025 - Dry cold front moves through the area today into tonight.
Conditions haven't changed much since this morning with High pressure still place. Models show some light rain moving into the far southern tier of zones as the low moved inland late tonight.
Generally periods of light snow will occur with this in western Montana and rainfall in the lower elevations of north-central Idaho. There is some concern that ground temperatures may be cold enough in the higher valleys including the Grangemont area of western Clearwater County that black ice could be an issue. Due to the periods of moderate to heavy snow, northeast winds to 30 mph, and the potential for flash freezing of roadways, we issued a winter storm warning for the Flathead Valley. When the warm front approaches tomorrow morning, snow will intensify, and snow will change to mixed precipitation in the Bitterroot Valley.
