1235 PM CDT Mon Oct 20 2025 - High pressure will spin the wind dial overnight with a wide range of temps from a chilly start to above average afternoon. The airmass that has brought seasonal temperatures clears out tomorrow morning, temperatures will return to the low to mid 80s for much of the region this week.
Northwesterly winds this afternoon will slowly shift more northward as the high moves in. NBM currently showing overnight lows down int the middle 40s, however would not be surprised to see a few areas briefly drop into the lower 40s by sunrise. Key message(s): - Warmer Tuesday, but dry weather likely continues ahead of a cold front.
354 PM EDT Mon Oct 20 2025 * Drier and cooler weather is expected for much of the upcoming week. * Another cold front will bring a small chance for a shower late tonight into Tuesday morning.
It's been a struggle to get any gusts above warning criteria (58mph) this afternoon, but will leave the High Wind Warning in place as the potential still remains through the daylight hours.
322 PM EDT Mon Oct 20 2025 High pressure will settle south of the area tonight. A cold front will cross the area late Tuesday night. High pressure will gradually build toward the region during the second half of the week, settling overhead at the end of the week. Warmer tomorrow under gusty southerly winds. Next upper low and associated cold front will cross the area Tuesday night with showers arriving in the mountains in the afternoon and spreading east during the evening. Very little moisture return ahead of this front with only brief light showers affecting areas east of the Blue Ridge Mountains. Cold front exits the area after 06Z Wed with precip ending. gradient finally relaxes which may allow for temps low enough to cause areas of frost or sub-freezing temperatures.
- Unsettled this weekend with breezy winds over the plains and rain/mountain snow over the higher terrain. - Meteorological Overview: A departing low pressure system has continued to bring a few light rain and mountain snow showers to portions of Central Montana today, particularly in and around the island ranges. Expect these showers to continue to dissipate through the evening as northwesterly flow develops ahead of a building upper level ridge.
- A cold front this evening will bring seasonal normal temperatures Tuesday.
102 PM EDT Mon Oct 20 2025 A fast-moving area of low pressure moving across the upper Great Lakes will bring a chance of precipitation late tonight into Tuesday.
133 PM EDT Mon Oct 20 2025 High pressure will build into the area through Tuesday. Another cold front will then arrive Tuesday night, with high pressure to follow. Satellite, radar, and surface observations indicate the cold front well offshore, with a cooler, drier airmass continuing to advect across the region. Expect lows to drop into the low to mid 40s across the inland counties, and low to mid 50s along the coastline. A reinforcing cold front will push through the region Tuesday night, with high pressure building in behind the front. Post-FROPA high temperatures will be slightly lower, reaching into the low to mid 70s.
1215 PM CDT Mon Oct 20 2025 Updated at 1212 PM CDT Mon Oct 20 2025 - Strong south winds this morning, shifting to the north behind a cold front in the afternoon/evening, with wind gusts up to 45 mph.
153 PM EDT Mon Oct 20 2025 Wrap around moisture will produce more showers today as low pressure exits the region. After brief high pressure on Tuesday, cooler and more unsettled weather moves in with chances for lake effect showers coming on cool northwest flow by mid week. Low pressure center moves into northern New England today and continues to deepen. Expecting some clearing tonight as brief ridging moves in for Tuesday. At this time, Tuesday is looking like the best day of the week with a weak progressive ridge over the area. However, clouds will start to increase late in the day as a highly amplified trough/upper low pushes into western NY. Another negatively tilted trough moves into the region Tuesday night, but this system will be less amplified and have limited moisture with it.
241 PM MDT Mon Oct 20 2025 KEY MESSAGES: - Gusty winds in excess of 50 mph from the northwest will persist today as the large low pressure system moves further east, keeping a Lake Wind Advisory in effect until 9 pm this evening. WEATHER PATTERN OVERVIEW: There still remain a tight surface pressure gradient today behind the departing low pressure system today, which has generated and will continued generate strong winds and gusts from the northwest. High pressure will bring clear skies which will allow temperatures to fall into the 20s tonight.
- A cold front brings cooler temperatures and a low potential for frost across far northwest Oklahoma Tuesday morning.
1235 PM CDT Mon Oct 20 2025 - Windy conditions today ahead of the strong cold front.
Temperatures remain on the cooler side of normal this afternoon in the wake of the upper trough the passed through the region. The pressure gradient remains tight this afternoon with the trough to our east and a building ridge to our west keeping breezy winds in place today. This gradient looks to relax later tonight and into tomorrow as the aforementioned ridge builds over the area. Expecting lows tonight to drop into the 20s for much of the area with maybe some lower 30s in parts of the Snake Plain and Magic Valley but most spots will likely drop below freezing tonight. Temps will moderate tomorrow as H5 heights rise as the ridge starts to exert its influence over our local weather.

639 PM CDT Mon Oct 20 2025 Updated at 627 PM CDT Mon Oct 20 2025 - Cooler temperatures this week with some cold nights.
Clear skies prevail across the region as high pressure continues to traverse the southeastern US. Many areas recorded dewpoints in the low 30s this afternoon, and even without ideal radiational conditions, we should easily see temps fall into the low to mid 40s most places tonight. Key message(s): - Warmer Tuesday, but dry weather likely continues ahead of a cold front.
Clear skies and lighter winds tonight will allow many lower valley sites to reach freezing, and the Freeze Warning remains in effect for the Treasure and Magic Valleys. That said, sheltered areas will still see temperatures dip to near freezing.
653 PM EDT Mon Oct 20 2025 A fast-moving area of low pressure moving across the upper Great Lakes will bring a chance of precipitation late tonight into Tuesday.
Otherwise, upper level ridging continues to build in from the southwest due to increasing convergence aloft expected to stay in place through the rest of the work week.
217 AM EDT Tue Oct 21 2025 Low pressure will slowly move across the upper Great Lakes over the next several days. A cold front extending south of the low will cross the area today with some showers occurring out ahead of it. This will drive a cold front through the area. Showers wrapping around the low could clip far northern counties, but most places will be dry. Upper low will lift northeast but long wave trough will persist and slowly translate eastward. Narrow ridge will develop as the trough exits, but it will be transient as a compact upper low in the southern Plains opens up and weakens as it pivots north northeast late in the period.
Upper zonal flow will become northwesterly today as large upper trough passes over the eastern CONUS. Weak upper ridging will then build over the region the latter half of the week. This reinforcing cold front will also bring in a very dry airmass behind it, with afternoon relative humidity values on Wednesday dropping to 15 to 20 percent, creating localized wildfire concerns.
1042 PM CDT Mon Oct 20 2025 Updated at 1020 PM CDT Mon Oct 20 2025 - A cold front brings cooler temperatures and a low potential for frost across far northwest Oklahoma Tuesday morning.
* A weak storm system passing through Tuesday night through Wednesday night will bring slightly cooler temperatures along with an increase in wind and slight chances for rain for portions of the area.

Updated at 113 AM CDT Tue Oct 21 2025 - Dry cold front brings temperatures back down to near normal for Tuesday.
Much cooler on Wednesday with the marine layer deepening further.
The trough fully exits the region overnight, and with clear skies, things remain on track for a quite chilly Tuesday morning. WV imagery shows the main trough across the upper Rockies pushing east as IR shows the colder cloud tops exiting into the High Plains with the quick moving cold front.
154 AM EDT Tue Oct 21 2025 High pressure builds across the Southeast states tonight, bringing calmer weather to our region briefly. A cold front crosses our area Tuesday night as low pressure gradually tracks just north of the Great Lakes through Wednesday.
CRITICAL TO NEAR CRITICAL HUMIDITY WEST OF I-95 THIS High pressure will prevail today, then a cold front will move through tonight. High pressure will build over the area through late week, then an upper disturbance will pass through late in the weekend. Through Tonight: Broad upper-level troughing will develop across much of the eastern CONUS today as vertically stacked low pressure propagates out of the Northern Plains and into the Great Lakes. This will help push a reinforcing cold front into the Deep South and parts of the Southeast U.
200 AM MDT Tue Oct 21 2025 - Some valleys are nearing or have fallen below freezing temperatures tonight.
A more robust system is expected to cross California this weekend, bringing in rainfall to the Valley and Foothills, and snow to the higher Sierra Nevada, all of which will likely be north of Kern County. Today is expected to be the warmest day of this week as the ridging pattern over much of the southwest and California continues through this afternoon. Then tonight, we are expecting a significant shift in the pattern as a weak, cut-off low is forecast to come onshore during the nighttime hours this evening.

315 AM EDT Tue Oct 21 2025 A cold front crosses our area tonight as low pressure gradually tracks just north of the Great Lakes through Wednesday.
248 AM CDT Tue Oct 21 2025 - Cold front will move across the area today and bring a chance for rain.
An associated surface cold front will bring low precip chances (10-25%) from the late morning and through the mid afternoon hours locally. However, clear skies, light winds, and a drier airmass will allow for overnight lows to trend a little cooler per late October standard.
- Lake Enhanced Showers With A Chance of Storms later Tuesday into Wednesday Behind the cold front, very cold air infiltrates the region as 850 mb temperatures fall below zero Celsius. Combined with the passage of a vorticity maxima associated with the large scale troughing lake enhanced showers are likely.
- Slightly cooler and drier conditions will move in Wednesday night through the rest of the week. High pressure surface and aloft will hold over the region through Wednesday with partly cloudy to mostly clear skies, light east to northeast winds, and temperatures several degrees above climatic normals.
- An upcoming pattern change at the end of the forecast period may point towards a cooler and wetter weather regime to end the month. A broad area of high pressure over Mexico is helping keep things zonal over the southern CONUS early this week.

Overnight lows tonight will once again drop below freezing in most areas.
High pressure is slowly building across the region, this morning would have been a perfect situation for valley fog and low level stratus clouds. The next few days will see high pressure assert its control. Expect warmer than normal temperatures and drier conditions.
115 AM MDT Tue Oct 21 2025 - Dry weather and a gradual warming trend for the rest of the week Water vapor imagery shows the upper low now crossing MN, with northwest flow across the CWA. A wave is rounding the backside of the low across the eastern Dakotas, where gusts over 50 mph are occurring. Upper ridging will build across the region in general, but there is a wave crossing the northern Rockies. Dry weather today will continue through the next several days, as upper ridging dominates the northern Rockies region.
- Frosty and freezing temperatures are again possible Wednesday morning.
Upper level ridging is still parked over the Desert Southwest providing dry conditions, clear to mostly clear skies, and near to slightly above normal temperatures. A stationary cut-off low is also positioned west of northern Baja with water vapor imagery showing very little system moisture. For our region today, expect daytime highs at or a couple degrees warmer than yesterday with lower desert highs around 90 degrees. These clouds will be aided by an upper level jet max moving into the region around the eastern periphery of the cut-off low. As the cut-off low tracks into southern California on Wednesday, portions of the region will see some increased breeziness focused during the afternoon hours.
Generally sunny conditions early in the day will support a continued warming trend, with highs reaching the upper 80s along the East Coast, and the low 90s across southwest Florida. Overnight lows will dip to the low-mid 70s across much of the region.
Updated at 131 AM CDT Tue Oct 21 2025 - Cooler temperatures expected today with highs in the 70s across the region.
311 AM EDT Tue Oct 21 2025 High pressure shifts offshore today as a cold front approaches and moves across the forecast area tonight. An approaching cold front will push through the forecast area this evening and into the overnight. As the cold front pushes through, 00Z guidance shows a line of light rain showers moving through the area. The line of showers is forecast to move through this evening after sunset, with precipitation chances highest for those east of the Blue Ridge.
Updated at 1020 PM CDT Mon Oct 20 2025 - Cooler temperatures this week with some cold nights.
- A dry cold front Wednesday will lead to breezy and gusty onshore winds once again late week and into the weekend.
Low rain chances (~15%) are forecast to return early Tuesday morning as a cold front moves eastward through the area. Showers are forecast to be out of the area by 20-21Z and dry conditions should filter in as the upper level trough exits the area to the east.
A dry cold frontal passage is occurring across the region early this morning, as a large low pressure system spins across the Upper Midwest.
Conditions remain warm and mostly dry across Deep South Texas for the majority of the forecast, through this week and into next, as ridging and subsidence aloft continue. A cold front will move southward through central Texas today, arriving near, or north of, the northern ranchlands this afternoon, lingering into tomorrow, shifting surface winds out of the east. This is expected to lead to an increase in showers and thunderstorms offshore the Lower Texas coastline late tonight as well as a low (15%) chance of isolated showers Wednesday afternoon along the seabreeze boundary east of US-281/I-69 C.

644 AM EDT Tue Oct 21 2025 Low pressure will slowly move across the upper Great Lakes over the next several days. A cold front extending south of the low will cross the area today with some showers occurring out ahead of it. Initial short wave and pre-frontal trough have resulted in scattered showers as they move across the area. This will drive a cold front through the area. Showers wrapping around the low could clip far northern counties, but most places will be dry. Upper low will lift northeast but long wave trough will persist and slowly translate eastward. Narrow ridge will develop as the trough exits, but it will be transient as a compact upper low in the southern Plains opens up and weakens as it pivots north northeast late in the period.
