618 AM CDT Mon Oct 14 2024 (Tonight through Tuesday night) Water vapor imagery this morning reveals upper level ridging stretching across the Southern Plains as an upper level trough digs across the Midwest. The upper trough will send a cold front south across the state early in the week. However, the low level moisture profile remains questionable for efficient fog production.
Water vapor imagery this morning showed an upper low along NV/UT state line. Heights/thickness values lower on Tuesday resulting in highs 3 to 6 degrees cooler than today.
The next system then brings cooler temperatures and generally light precipitation chances by midweek, with breezy to gusty northerly winds and elevated to critical fire weather concerns following through the end of the week. As ridging continues over the area, we can generally expect mostly clear skies and calm conditions through early this week. Ensembles and cluster analysis show a continued increase in confidence around a trough digging southward from the Gulf of Alaska toward NorCal mid-week this week.
252 AM PDT Mon Oct 14 2024 * Fair weather and warmer afternoons return today and Tuesday.
559 AM CDT Mon Oct 14 2024 - A cold front will bring cooler temperatures this week. (Today and tonight) A weak cold front has moved through half the area this morning and will return east as a warm front tonight.

456 AM MDT Mon Oct 14 2024 - Near freezing temps early this morning. - Warmer temperatures return during the first half of the week, along with elevated fire danger. - Cooler and more unsettled late week. Then a change to wetter and cooler weather is expected for the second half of the week. Winds gusts anywhere from 5 to 20 mph are keeping temperatures from dropping to near freezing. The areas that are near or below freezing are all in wind-sheltered locations, such as river valleys. Another strong high pressure will slide southward from Canada to Minnesota and Iowa on Tuesday. The baroclinic zone, which will move eastward today, will slide back west on Tuesday, resulting in temperatures 5-10 degrees cooler than today.
602 AM CDT Mon Oct 14 2024 - Nighttime lows are expected to be near or below freezing tonight across northeast Nebraska, and tomorrow night across all of eastern Nebraska and western Iowa.
A weak high pressure sits across the Gulf of Mexico, which is maintaining light to gentle north to northeast breezes across the region. Meanwhile, aloft ridging remains stalled across the northwestern Caribbean and over Cuba. Weak high pressure over the Gulf of Mexico will maintain light to gentle mainly northeast breezes across the Keys coastal waters through Tuesday night.
624 AM CDT Mon Oct 14 2024 (Today through Tuesday) Tranquil weather is expected through Tuesday as high pressure aloft and at the surface remains in place. Highs today and Tuesday are expected to be slightly above normal with temperatures generally in the low to mid 90s under mostly sunny skies.
(Today through Tuesday) Highlights: - A cold front will usher in cooler and drier air to the area. A broad upper trough will continue to dig over the E half of the U. At the surface, a cold front across N GA will sweep S of the County Warning Area by this evening. This front will usher in drier and cooler air. As a result, relative humidity values will drop into the lower to mid 20s this afternoon, and a Fire Danger Statement has been issued for all but the extreme NE and S.
529 AM EDT Mon Oct 14 2024 Cooler and unsettled weather is then expected through midweek under a trough of low pressure.

(Tonight through Tuesday night) Pleasant weather is expected to persist through Tuesday night with high pressure aloft and at the surface, as they continue to be the driving forces for the weather of Deep South Texas and the Rio Grande Valley. As for the temperatures, the highs for tomorrow are expected to be in the low to mid 90s. Meanwhile, the low temperatures for the tonight and tomorrow night are expected to be mostly in the 60s. However, areas along the coast could be in the lower 70s.
Scattered showers return over the area Tuesday mainly along and north of interstate 40, and especially across the higher elevations. Rain will change to light snow/sleet across the highest elevations late Tuesday and Tuesday night. Light snowfall possible across the highest elevations, generally above 4kft, with 1/2 to 1 inch. Much cooler Tuesday, with lows dropping into the 30s lower elevations, and 20s high elevations. Discussion: For tonight, surface ridging and dry airmass will produce a mostly clear to partly cloudy (southwest Virginia/northeast Tennessee). The wave will usher in much cooler air aloft helping to steepen the low- level lapse rates producing scattered showers mainly along and north of interstate 40. The light snowfall, temperatures in the 20s, and breezy northerly winds will produce dangerous conditions across the higher elevations if you not prepared.
- Temperatures moderate though late week as high pressure brings dry conditions. Robust lake effect response in the wake of departing low pressure today supporting widespread BKN lower VFR clouds. This will offer a cool day today with high temperatures in the low 50s for much of the forecast. Expecting plenty clouds over the region today supported by the cold airmass moving over the relatively warmer Lake Huron.
- Temperatures moderate though late week as high pressure brings dry conditions. Deep polar vorticity anomaly and closed upper level low circulation is currently positioned over eastern North America, including the Great Lakes.

206 PM CDT Mon Oct 14 2024 - Nighttime lows are expected to be near or below freezing tonight across northeast Nebraska, and tomorrow night across all of eastern Nebraska and western Iowa.
Later that night, an elongated upper level trough over the Northeastern CONUS should push a slog of cooler, drier air into SE Texas overnight. This should usher in cooler weather, with overnight lows in the 50s to lower 60s.
Confidence continues to increase in a major change coming Wed, with a strong cold front and widespread rain event, with snow levels coming down rapidly behind the front.
231 PM CDT Mon Oct 14 2024 - Below freezing temperatures expected tonight into Tuesday morning in the central and east. Freezing temperatures are possible in the west as well, though uncertainty remains much higher due to potential cloud cover and breezy conditions.
- Expect cooler temperatures through mid-week as northerly flow ushers in cold Canadian air. As temperatures fall into the low to middle 30s, a Frost Advisory or Freeze Warning may be needed over east-central Wisconsin on Tuesday night, where the growing season has not concluded.
- Elevated fire weather concerns for Tuesday - A cold front will bring cooler temperatures this week. (This evening through Tuesday) Early this afternoon, a cold front was stalled just north of the Interstate-10 corridor. Temperatures across the area ranged from the 80s behind the front to the low 90s ahead of the front. This front should lift back northward as a warm front late this evening and overnight and allow southerly flow to return for the area through Tuesday afternoon. Although winds are not expected to be particularly strong, they should advect a warm airmass back into the region and push high temperatures up into the low 90s tomorrow.
1215 PM EDT Mon Oct 14 2024 Cooler and unsettled weather is then expected through midweek under a trough of low pressure. KEY MESSAGES: - Precipitation chances will increase from the north with a sagging trough over the Great Lakes. 10 or greater will be over the northern counties and over the higher terrain in WV and not much potential with only 40% to 50% chance.
/29 (Now through Tuesday night) A large upper trof over the eastern half of the CONUS amplifies substantially and becomes oriented over the eastern states while a large upper ridge builds over the central states. A cold front currently located near the coast pushes well offshore tonight followed by cool high pressure building into the area through Tuesday night. Lows tonight range from around 50 well inland to around 60 at the coast, then Tuesday night will be cooler with lower 40s well inland ranging to the lower 50s near the coast.
249 PM EDT Mon Oct 14 2024 The passage of a cold front today will usher in the coldest and driest air mass of the season thus far. A reinforcing cold front will push through Tuesday night with possible isolated showers over the northern Midlands with below normal temperatures expected for the remainder of the week. Key Messages: - Breezy winds today behind a cold front A cold front is moving through the Southeast during the near term. The cold air will lag behind the front, so daytime temperatures won't be much cooler than the previous day.
203 PM CDT Mon Oct 14 2024 Cooler and drier air has moved in behind the cold front, that pushed through the state yesterday. Across the state, cooler temperatures are being observed with some gusty winds and mostly clear skies.
Pattern/synopsis: High pressure in northern Manitoba extends ridging down into the central plains. Cold advection continues ahead of this ridge. The high moves bodily southward, west of the Great Lakes, thru the short term. Highs stuck in the low-mid 40s on a chilly, chilly Tuesday. Pattern Synopsis and Forecast: Northerly to NNW flow on the backside of a departing low pressure/energy aloft and east side of a building high pressure is expected Tuesday night.

Cooler weather can be expected Tues with WAA ramping up in the afternoon in the west, supporting pressure falls and increasing SE winds esp over northwest SD. Upper trough will move east into the Rockies and support a cold front thorough the region Thurs with continued breezy winds. Cold front aloft will move into the west later Thur and provide the focus for lift and associated rain and possible snow.
1155 AM EDT Mon Oct 14 2024 Cooler and unsettled weather is then expected through midweek under a trough of low pressure. KEY MESSAGES: - Precipitation chances will increase from the north with a sagging trough over the Great Lakes. 10 or greater will be over the northern counties and over the higher terrain in WV and not much potential with only 40% to 50% chance.
344 PM EDT Mon Oct 14 2024 A dry cold front moving offshore this evening will precede a stronger cold front harboring a few stray showers on Tuesday night. The cold front is mostly through the area, looking like its just west of US 17. The edge of the drier, cooler air is juts pushing into our inland counties where they've likely hit their high temperatures for the day. Cloud cover will increase ahead of another cold front during the late afternoon/evening but otherwise not much to write home about.
Slightly above average temperatures for the next couple of days due to high pressure.
The cold front that moved through last night has caused temperatures to stay in the in the upper 60s to lower 70s this afternoon.
(Tonight through Monday) Cold front remains timed to sweep quickly southward across the local region during the day Tuesday.
The polar jet is aiding in amplifying a deep trough across the Great Lakes and NE CONUS regions, which will have a surface cold front pushing southwards along the leading edge of the trough. For morning lows, the Lake region and interior areas will cool down into the mid-upper 60s, while the coastal metro areas will remain in the low 70s.
1246 PM CDT Mon Oct 14 2024 - Widespread sub-freezing temperatures tonight. Winds have weakened substantially early this morning, following the eastward departure of an upper low and resultant relaxation of the surface pressure gradient. Temperatures in the upper 30s/low 40s will continue to fall a few more degrees overnight, likely near or below freezing in central Minnesota. Clear skies, light winds, and sub-freezing 850 mb temperatures will work in tandem to promote efficient radiational cooling.
Global guidance shows a slow moving cold front stalling along the Gulf Coast.
1249 PM CDT Mon Oct 14 2024 (Today through Tuesday afternoon) After several hot days, a cold front has finally arrived. If you happen to be off for Columbus Day, get out and enjoy the "cooler" conditions.
(This evening through Tuesday night) Large upper trough over the Great Lakes with a lobe over Lake Superior. Cooler and drier air will be plunging into the area overnight tomorrow night, and there is at least a small chance that a brief Wind Advisory may be necessary immediately south of Lake Pontchartrain during the overnight hours Tuesday night.
238 PM EDT Mon Oct 14 2024 (This afternoon through Tuesday) Broad upper troughing continues to dig across the Eastern US and a sfc cold front continues southward currently situated in the vicinity of Columbus and Macon. Cooler temperatures can be expected overnight with forecast lows ranging from the mid to upper 30s in NE GA to upper 40s to near 50 in the south. This will bring a reinforcing cooler and drier airmass into the region that will stick around through much of the weekend. Cooler daytime temperatures can be expected on Tuesday with highs ranging from the upper 50s in NE GA to low 70s south of Macon.
(Through Tuesday) A dry cold front continues to move through the region this afternoon and evening, ushering in a cooler and much drier air mass. Highs on Tuesday ranging from the mid-70s to mid-80s, about 5-10 degrees cooler compared to Monday, with very comfortable humidity levels.
