Aikyam-Lab/Synoptic-Bench huggingface dataset:
A weak cold front is expected to move through the area Tuesday, bringing cooler temperatures and northerly winds in itâs wake. Low temperatures tonight look to range from the low 50s to low 60s tonight and Tuesday night, while afternoon highs on Tuesday look to be in the mid 70s to low 80s.
342 PM EST Mon Dec 30 2024 Low pressure will approach the area tonight and move through on Tuesday. Colder air will come in behind the low, marking the beginning of a prolonged period of below normal temperatures. Low pressure will move from central Indiana into northeast Ohio on Tuesday. On the backside of the low, scattered showers will persist but gradually decrease in coverage going into the overnight. In the cold advection behind the low, winds will gust up to 30 mph. Lows Tuesday night will be in the lower to mid 30s.
1111 AM CST Mon Dec 30 2024 Updated at 1106 AM CST Mon Dec 30 2024 - A few more showers on NYE and then trending cooler by NYE night with temperatures falling into the 30s. - Turning colder late this week as a stronger cold front moves through.
This morning's scattered clouds and light winds contributed to slightly warmer temperatures to start the day. This could lead to warmer valley temperatures tonight and possibly cooler conditions Tuesday afternoon. Maximum temperature forecasts for today have been updated to reflect the warmer minimum temperatures observed this morning.
409 PM EST Mon Dec 30 2024 Weak high pressure will bring quiet weather tonight. Low pressure currently over Missouri will move up the Ohio River valley on Tuesday bringing rain.
Based on this latest trend it appears that the High Wind Warning will be allowed to expire at 6 pm. the humidities were increasing this evening so will allow the red flag warning also to expire at 6pm this evening 19z upper air analysis and surface observations show a departing surface 998 mb low in southeast Kansas with a tight pressure gradient in the high plains as the result of a high pressure center in the Colorado Rockies. Despite insolation the 850 mb temps will rise to only -2 to -4 (C) by afternoon and NBM output has mean highs in the low 40s.
These very strong northwest winds should continue to affect central/south central Kansas through the evening hours, as 1000-850mb lapse rates remain steep/well mixed for transporting the higher winds aloft to the surface. Cooler air will over spread the central plains for the rest of the week with daytime highs closer to seasonal averages.
- High temperatures tomorrow will be 5 to 10 degrees cooler than those seen today.
- Above-normal temperatures are forecast Tuesday with colder and below normal temperatures forecast behind a cold front mid week. A cold front is situated over the local Atlantic waters.
932 PM EST Mon Dec 30 2024 Temperatures will trend cooler throughout the week, but remain above average through midweek.
(This evening through Tuesday night) Based on current GOES-16 water vapor imagery, there is an mid to upper level low moving across SD/NE. An associated jet with this low is bringing some stout winds aloft over the combined Panhandles and surrounding areas, over 100 kts above H3. This low will continue to progress to the E to NE this evening and tonight. As this low progresses the pressure gradient will gradually relax this evening and more into tonight. Cold air will fill in behind the low with a cold front expected to bring cooler temperatures back into the FA tonight and tomorrow. Much of the area will only see an afternoon high in the 40s, 20 degrees cooler than the last couple of days.
Moist, northwest flow will continue to support upslope enhancement over the northern Black Hills through this evening with the potential for the higher elevations of the northern Black Hills to pick up an additional 4 to 8 inches through this afternoon and evening.
Morning occurrences of Tule Fog will be conceivable through the week as high pressure aloft persists.
WEATHER PATTERN OVERVIEW: Transition into a more winter pattern occuring with a broad trough over central Canada drawing arctic air southward. Toward the end of the week a strong Pacific trough pushes an upper ridge over the state, bringing Pacific moisture across the arctic airmass and potentially producing a significant overrunning snow event over the weekend.
Once skies cleared and winds picked up, most of the CWA reached the lower 70s generally south of I-20 and mid to upper 60s north of I-20. A gradient has developed ahead of an approaching low pressure system and cold front. The boundary will bring in some much cooler air, but has a very low chance of rain. Highs tomorrow are expected to remain in the 60s and lows in the lower to mid 30s are likely. Unfortunately, winds will pick up across the area again by mid morning, so it will feel like it's in the 50s or cooler into the afternoon.
551 PM CST Mon Dec 30 2024 A generally cooler and dry weather pattern is expected this week, with temperatures falling a little each day.
704 PM EST Mon Dec 30 2024 Weak high pressure will bring quiet weather tonight. Low pressure currently over Missouri will move up the Ohio River valley on Tuesday bringing rain.
708 PM EST Mon Dec 30 2024 Low pressure will approach the area tonight and move through on Tuesday. Colder air will come in behind the low, marking the beginning of a prolonged period of below normal temperatures. Low pressure will move from central Indiana into northeast Ohio on Tuesday. On the backside of the low, scattered showers will persist but gradually decrease in coverage going into the overnight. In the cold advection behind the low, winds will gust up to 30 mph. Lows Tuesday night will be in the lower to mid 30s.
- A cold front is moving through the region this evening which will result in near to below normal temperatures for the rest of the workweek.

647 PM EST Mon Dec 30 2024 Temperatures will trend cooler throughout the week, but remain above average through midweek.
Updated at 130 AM CST Tue Dec 31 2024 - A few light showers today mainly across the Cumberland Plateau with cooler and drier air moving in for NYE festivities.
- Comparatively much cooler but near normal temperatures today. (Today and tonight) In the wake of the overnight cold frontal passage, temperatures today will be much cooler compared to yesterday, but actually close to normal for the end of December. Overnight lows are expected to be mostly in the lower 30s, but a few upper 20s are possible in favored low-lying areas where.
243 AM EST Tue Dec 31 2024 Pacific high pressure will linger near the South Atlantic coast tonight.
124 AM EST Tue Dec 31 2024 Low pressure will approach the area tonight and move through on Tuesday. Colder air will come in behind the low, marking the beginning of a prolonged period of below normal temperatures. Low pressure will move from central Indiana into northeast Ohio on Tuesday. On the backside of the low, scattered showers will persist but gradually decrease in coverage going into the overnight. In the cold advection behind the low, winds will gust up to 30 mph. Lows Tuesday night will be in the lower to mid 30s.
THIS EVENING TO TONIGHT FLURRIES TO FREEZING DRIZZLE: A weak cold front is draped from northwest Ontario into the northern U. While the forecast currently favors very light snowfall, a mix of freezing drizzle cannot be entirely ruled out as well from northern Cass to the Iron Range and northward through late tonight. FOG THIS EVENING TO LATE TONIGHT: Ahead of the weak cold front, lingering low-level moisture in northwest Wisconsin and the Arrowhead is expected to again create another period of patchy dense freezing fog. LIGHT SNOW NORTHERN MN TUESDAY: With the mid-level trough axis passing overhead throughout Tuesday daytime, mid-level vort maxes are expected to aid in continued light snowfall chances for northern Minnesota.
Updated at 150 AM CST Tue Dec 31 2024 - Temperatures closer to normal today in wake of strong cold front.
Updated at 246 AM CST Tue Dec 31 2024 - Much cooler today behind a cold front.
Ridging aloft will then build in for late week with warming temperatures.
Temperatures in early January fluctuate between near and above-normal values as passing systems bring periods of increased winds and cooler air.
With the cooler airmass that moved into the region behind the front that moved across the area yesterday, around average temperatures are expected this afternoon. The highs today will be about 20 degrees cooler than yesterday. Cooler temperatures are also expected tonight with lows in the 20s to low 30s across the area.
(Today and tonight) In the wake of the upper low that brought strong winds yesterday, will be decent westerly flow aloft but weak ridging at the surface. Yesterday evening's cold front has pushed south into deep Texas early this morning with north winds and cold air advection filling in behind the frontal boundary. Temperatures today are expected to be nearly 20+ degrees cooler than yesterday with highs in the upper 40s to lower 50s. Despite the high clouds, temperatures will still plummet to near or below freezing across the entire forecast area. The coldest temperatures will be across the far southwest Texas Panhandle and north and northwestern portions of the Plains with lows in the lower to mid 20s.
The dry cold front as of 31/03z extends through far northeast Texas into southwest Arkansas. The cold front will continue to push to the southeast and usher in some cooler air for tonight and Tuesday. The passage of a cold front tonight and the eventual cold advection will result in a cu field spilling SSE across SE OK/much of AR by afternoon, possibly affecting the TXK/ELD terminals before diminishing by sunset.
1034 PM EST Mon Dec 30 2024 Low pressure will approach the area tonight and move through on Tuesday. Colder air will come in behind the low, marking the beginning of a prolonged period of below normal temperatures. Low pressure will move from central Indiana into northeast Ohio on Tuesday. On the backside of the low, scattered showers will persist but gradually decrease in coverage going into the overnight. In the cold advection behind the low, winds will gust up to 30 mph. Lows Tuesday night will be in the lower to mid 30s.
The main impact from this system however will be the lobe of arctic air expected behind this wave, mainly impacting NW through central SD where the highest probs for the coldest temps are.
346 AM EST Tue Dec 31 2024 A cold front will cross the area tonight, followed by a cooling trend through the rest of the week with much colder air for the weekend. The fog ends later this morning as boundary layer winds kick up ahead of an approaching cold front, with sfc gusts up to 15-25 mph this aftn. Temps today a bit warmer than those of yesterday.
1120 PM CST Mon Dec 30 2024 A generally cooler and dry weather pattern is expected this week, with temperatures falling a little each day.
(Tuesday through Wednesday) Latest surface analysis showcases that a cold front is working south across the SHV CWA this morning, with a healthy dose of CAA on the backside of the FROPA. Post frontal airmass will settle in through the afternoon, with just enough influence to support cooler highs in the upper 50's and low to mid 60's. Winds should remain slightly elevated this afternoon, which in return will keep temperatures feeling slightly cooler when compared to a scenario where calm winds prevailed in the post FROPA airmass under the expected mostly clear skies. Influence of the post frontal airmass will be most notable on New Years Day as highs will only climb into the low and mid 50's for many, flirting close to 60 deg F across the extreme southern counties and parishes.
Cooler air wl cont to advect into the Natural State today as gusty northwest winds cont. The start of the new year wl rmn quiet acrs the Mid-South as high pressure rmns in control. Highs New Years Day wl be fairly close to normal, ranging fm the lower 40s to the lower 50s.
The weak stationary front will lift slightly north as a warm front as this occurs. Highs south of the boundary will be back into the lower 40s across southwest Nebraska south of the front. Main concern for snowfall in our area is the dry air in the lower levels that will be tough to overcome. However, sounding profiles have a tough time overcoming the drier air in the low-levels, with much of the precipitation evaporating before ever reaching the surface.
- For those out celebrating the start of 2025, it will be mostly cloudy with temperatures in the lower and mid-20s.
Another trough in the northwesterly flow is on track to move into the Northern Rockies by Wednesday morning. While model guidance consistently points to an active weather pattern through the weekend, differences in the timing and distribution of moisture and troughs reduce confidence in the finer details. Patchy fog may develop overnight, but conditions will quickly change with the arrival of the next trough on Wednesday morning.
325 AM CST Tue Dec 31 2024 - Mostly cloudy, dry, and blustery afternoon today as colder air (near 40 degrees for highs) arrives behind the cold front.
- Cooler temperatures slowly warm through the week, then the weekend poses a chance to be much colder, however a lot of uncertainty remains still.

As high pressure settles in overnight, gradient will relax, but light sfc wind will continue. High temperatures Wednesday will range from the upper 40s across the northern portions of the CWA to the lower 60s across the southern portions.
338 AM MST Tue Dec 31 2024 - High temperatures today will be 5 to 10 degrees cooler than those seen yesterday as a colder air mass moves in behind yesterday's departing system.
441 AM MST Tue Dec 31 2024 - High temperatures today will be 5 to 10 degrees cooler than those seen yesterday as a colder air mass moves in behind yesterday's departing system.
MSAS analysis depicts a cold front to our west across Mississippi. Ahead of this boundary, a weak warm front is lifting through the region. This cloud coverage will likely keep our low temps a couple of degrees warmer this morning. The aforementioned cold front will swing through the region today. Lows tonight will fall into the low to mid 30s for most.
Issued 311 AM CST Tue Dec 31 2024 Today through Wednesday: Low pressure is moving east across central Illinois and Indiana early this morning. Overnight lows will be in the low 20s, with a steady northwest breeze.
The rain bands will shift northward as the low moves to the east. The latest CAMS have shifted the low further south which could shift the heaviest snow bands to the south as well. However, between 4 pm Tuesday to midnight Wednesday there is well defined frontogenetic forcing along with strong winds through the low levels. The biggest question is how much accumulates due to the daytime temps that should remain above freezing, and the warm road temperatures. Synoptic snow showers will fade early Wednesday as the low moves to the east and cold air behind the front infiltrates southern Michigan.

522 AM CST Tue Dec 31 2024 (Today) Upper low/trough pattern continues to rotate eastward thru the Midwest region this early Tue morning, with an area of stratus clouds moving over the central/eastern half of the area. As the upper trough axis rotates further into the OH Valley states later this morning, additional cloud cover will spread eastward into much of the mid TN Valley. Breezy winds will develop as the front begins to move thru the region, with veering winds to the west near 15-20MPH and gusts around 25-30MPH, especially in the higher elevations. With the influx of cooler air likely delayed until tonight, highs look to climb into the mid/upper 50s for most spots.
219 AM MST Tue Dec 31 2024 Dry conditions with daily highs mostly in the lower 70s will continue for the rest of the week.
(This afternoon through Wednesday) The cold front continues to move down I-49 into S LA now with 30 degree dew points areawide for us. Fog in cenLA has dispersed and the high pressure will bring down a chilly evening for revelers with temps falling through the 40s this evening and still a little wind chill to boot. Skies are clear now with some partly cloudy conditions at most later today in the base of the trough or some late day cirrus. Fair skies are expected tonight and the low level winds will remain brisk.
