153 PM EDT Mon Oct 23 2023 High pressure remains over the region for much of the new work week, making for clear skies. Key message: Frost in Southside VA, warming begins Tuesday Abundant sunshine and dry high pressure is allowing temperatures to warm considerably and make it feel much different than last night's much colder setup. Keeping it dry with warming temperatures this period as operational and ensembles feature a strong 5h ridge over the southeast U. The ensembles in general start to give the ridge a flatter look heading toward Monday as an upper trough tracks across the Canadian Prairies into the Great Lakes. High pressure continues to maintain VFR conditions with clear skies, light winds and no active weather expected through the 24 hour period. No significant restrictions anticipated as high pressure is expected to remain over the area.
345 PM EDT Mon Oct 23 2023 High pressure will build across the Northeast over the next couple days. Fair weather will continue this afternoon and evening with light and variable winds through the evening as the upper level ridge shifts east and the center axis is over Central NC Tuesday morning. Overnight expect good radiational cooling with temperatures dropping into the low/mid 30s in the colder spots, with warmer spots in the mid/upper 30s. The best chance of frost tonight will be in the northern Piedmont and northern Coastal Plain, but some cooler spots in the Sandhills and southern Piedmont could see conditions close enough that result in frost. Mid/upper level ridge will build over NC on Tuesday bringing another day of fair weather.
1233 PM EDT Mon Oct 23 2023 Warmer air will overspread the area with highs tomorrow likely reaching well into the 70s.
Another calm and clear night, with slightly warmer overnight lows. Discussion: High pressure still in place overnight which will lead to another calm and clear night. For most places, overnight lows will be around 5 degrees warmer compared to last night. Tomorrow, high pressure shifts even further northeast and the southeasterly flow becomes a little stronger. A very dry airmass is still in place and afternoon min RH will range from the low 20s to low 30s for most places. The low afternoon RH combined with the slight increase in winds, mostly across the southern TN Valley, fire weather concerns will be slightly elevated compared to today.
355 PM EDT Mon Oct 23 2023 High pressure will allow for dry conditions tonight through the day on Tuesday.
(Tonight) Little change in the overall pattern is expected into tonight, as high pressure remains layered across the NE/mid Atlantic states, while an upper ridge axis builds over the western/central Gulf regions. With the building upper ridge pattern, coupled with light sfc flow turning more to the SE, overnight temps look to trend a few degrees warmer compared to the last couple of nights, with early morning lows Tue more in the lower/mid 50s for most spots.
The low level jet ramps up Tuesday night across C and E OK with chances for rain and scattered storms across most of the area.
1001 AM CDT Mon Oct 23 2023 The front is approaching the Devils Lake basin bringing rain, cooler temperatures in the upper 30s and 40s, and clouds. -A cold front sagging into the region will result in a large spread in potential temperatures, with above average/mild temperatures gradually shifting southeast over the next few days. As that occurs a cold front begins to slide into north central ND and eventually northeast ND and WAA/frontogenetical interactions will help organized an area of rain/embedded banding that is favored by HREF to track between Hwy 200 and along Hwy 2.
200 PM PDT Mon Oct 23 2023 A low pressure trough will continue the much cooler weather with diminishing light rain showers from the mountains west to the coast the rest of this afternoon. Fair and slightly warmer weather will occur Tuesday.
Temperatures along the Island Chain are in the lower to mid 80s with dew points in the upper 60s to near 70 degrees.
1220 PM CDT Mon Oct 23 2023 (Today through Tuesday) Key Messages: - Isolated showers/storms today through Tuesday - Moderate risk of rip currents through Tuesday Slight rain and thunderstorm chances (20-30%) can be expected across portions of South Texas today through Tuesday as southwesterly flow aloft brings in deeper Pacific moisture and a few disturbances ahead of a low pressure system crossing into the Baja Peninsula. At the lower levels, a tighter pressure gradient resulting in breezy conditions will bring in some pockets of deeper moisture from the Gulf waters. The rainfall potential will mostly be confined to areas east of I-37 today, with some slight chances possible out west tonight as a low level trough traverses Mexico.
149 PM EDT Mon Oct 23 2023 High pressure building into the region will bring pleasant conditions and decreasing wind today. High pressure continues to build throughout the day with lingering clouds continuing to dissipate as flow shifts to the south. High pressure remains in control through the middle of the week which will keep the area dry.
(Tonight through Tuesday night) High pressure continues to dominate the southeastern US today. Expect much of the same tomorrow as the high pressure dome starts to shift southward toward the GoM. Very warm temperatures are expected as well with high temperatures topping out in the lower 90s this afternoon and again tomorrow. Once again, building seas along the Lower Texas Coast tonight through Tuesday will result in a High Risk of rip currents at the local beaches.
More showers and thunderstorms are expected to develop across the Southern Plains on Tuesday as the remnant low of Norma ejects northeast, and large scale forcing strengthens ahead of a strong upper trough digging into Northern Mexico. Can't rule out a few showers moving into Southeast Oklahoma and portions of Northeast Texas by late Tuesday afternoon, but with upper ridging building across the Lower Mississippi Valley, most of the precip should stay west of our CWA. With more mid to high level clouds across our East Texas and SE Oklahoma zones, expect highs in the lower 80s.
203 PM EDT Mon Oct 23 2023 High pressure will drift into the region today, providing abundant sunshine and near to slightly below normal temperatures. Midlevel ridging will expand northward into the OH Vly tonight into Tuesday, allowing for notably warmer temps to filter into the region by Tuesday into midweek. With ridging centered over the SE CONUS and troughing developing over the wrn CONUS, broad SW flow will become established from the lower MS Rvr Vly and south-central plains into the OH Vly for midweek and beyond.
300 PM MDT Mon Oct 23 2023 Current surface analysis shows cold front has passed through most of the area, now over south central South Dakota. Upper level analysis shows near zonal flow across the region, with a trough over the Great Basin region and CA. Temps range from the 50s over northeast WY, the Black Hills, and northwest SD to the lower 70s over south central SD. A big change in the weather will take place later this week as a large Canadian trough sinks south across the western US, bringing much colder air and occasional chances for pcpn.
1000 AM PDT Mon Oct 23 2023 A low pressure trough will bring much cooler weather, light rain showers from the mountains west to the coast today. Fair and slightly warmer weather will occur Tuesday.
1229 PM EDT Mon Oct 23 2023 High pressure building into the region will bring pleasant conditions and decreasing wind today. High pressure continues to build throughout the day with lingering clouds continuing to dissipate as flow shifts to the south. High pressure remains in control through the middle of the week which will keep the area dry.
312 PM EDT Mon Oct 23 2023 Key Messages: - Warmer low temperatures expected tonight - Dry weather continues on Tuesday; mid- and high-level clouds increase through the day --------------------------------------------------------------------- This afternoon, mostly sunny skies abound across central Kentucky and southern Indiana. Upper level cloud cover moving across the top of a developing ridge will continue to stream across southern KY later this evening. These mid and high clouds will gradually push farther north overnight tonight as ridging across the southeastern U.
A low pressure system will dive southward across the western states into Mexico today and Tuesday. As a result, look for cooler temperatures today with gusty winds developing by this afternoon. An elongated trough of low pressure to our west will consolidate into a closed low over Central Baja tonight.
Heavy Rainfall and Localized Flash Flooding Tonight and Tuesday The main impact form the remnants of Tropical Cyclone Norma will be a rapid increase in showers and widely scattered thunderstorms with localized flash flooding tonight into Tuesday morning across much of the area.
BB/03 (Now through Tuesday) Warm and benign conditions expected through Tuesday as a ridging over the southern Gulf builds northward. Expect dry conditions to continue with warm temperatures as subsidence clears out most clouds and east southeasterly winds allow for warmer gulf air to slowly move northward.
350 PM EDT Mon Oct 23 2023 High pressure begins to build in and most areas will see a mostly clear to clear sky tonight.
Key Messages: - Warmer temperatures will hold on for a few more days.
- Turning much colder by the weekend A deep and slow moving longwave trough (currently centered over Baja California) is the main focus for impactful weather this week.
220 PM EDT Mon Oct 23 2023 High pressure will build down and over the region during today.
402 PM EDT Mon Oct 23 2023 Dry high pressure will prevail across the region this week, and possibly into this weekend. Cool high pressure will remain just north of the area tonight. A strong, deep layer ridge continues to be depicted by all models to build over the southeast U. At the surface, a ridge of high pressure will be centered over the Mid Atlantic states, and extend southwest into our area. With a building ridge, temperatures are also expected to gradually warm through the week.
1222 PM CDT Mon Oct 23 2023 (Rest of Today) High pressure layered across the NE/mid Atlantic regions, coupled with an upper ridge building over the western/central Gulf states, will translate into dry/seasonably warm conditions well into the afternoon hrs, with highs climbing mainly into the upper 70s/near 80F.
1037 AM MDT Mon Oct 23 2023 Key messages: - Cold front today will bring cooler air from northwest to southeast - Much colder temps and light snow expected late Wed/Thu - Cold this weekend, with another chance for light snow Upper flow is split, nearly zonal across the northern plains as a low slides south over CA. At the surface, an inverted trough stretches through the Rockies and into the Dakotas, with Canadian high pressure slowly pushing south behind a cold front. Cold front is expected to cross 2/3 of the CWA by 18Z and nearly all of the CWA by 00Z, so lowered highs a smidgen, leaving south central SD the warmest. Highs will range from the low 50s across northeastern WY, northwestern SD, and the Black Hills to the mid 70s across south central SD.
57" today, which is the highest in a single day all year.
131 PM EDT Mon Oct 23 2023 High pressure builds in from the west through tonight. The high then gradually builds offshore Tuesday and remains over the Western Atlantic through the week.
High pressure to our east will pump increasingly warmer and more humid air into the region. A frontal boundary will attempt to push into the region during the second half of the work week, but this will be rebuffed by the high pressure ridge centered across the southeast CONUS.
1242 PM CDT Mon Oct 23 2023 (Today through Tuesday) Upper level ridge is going to be building over the eastern half of the US for the start of the week. (Tuesday Night through next Monday) Long wave troughing will be developing over the West mid-week but the upper level ridge will keep things quiet and warm for us. The long wave trough will slowly start to push east towards the end of the week into the weekend.
A trough will continue tracking south along the California coast.
1210 PM EDT Mon Oct 23 2023 High pressure builds in from the west through tonight. The high then gradually builds offshore Tuesday and remains over the Western Atlantic through the week.

We're starting out this afternoon with a cold front progressing east- southeast across the forecast area.
Very warm weather will continue across the Mid-South through the weekend as upper level ridging prevails across the region. Expect highs in the lower to middle 80s. A cold front will stall north of the region by the end of the week into the weekend with chances for showers mainly north of Interstate 40.
As a closed upper low will moves towards the Washington coastline later in the day Tuesday, expect clouds to begin to increase region-wide as precip shield begins to move in after sunset tomorrow leading to a prolonged period of active weather.
1233 PM CDT Mon Oct 23 2023 (Today through Tuesday) The BRO CWFA will remain on the western periphery of 500 mb high pressure, which will build northwest and re-center itself from the Florida Straits to the northeast Gulf of Mexico. Dry weather will prevail across Deep South Texas and the Rio Grande Valley, and if any isolated to scattered convection does occur, it will be located over the lower Texas coastal waters. Finally, building seas along the Lower Texas Coast tonight through Tuesday will result in a High Risk of rip currents at the local beaches.
Warm conditions are occurring across the area this afternoon as temperatures are currently in the low to middle 80s. Clouds will start to increase tonight into Tuesday as an upper level trough moves towards the area. Scattered showers will develop late tonight into Tuesday morning as the lift from the low level jet occurs. As the upper level trough moves through the region, additional showers and a few storms will develop and move across the area Tuesday afternoon and evening. A warmer air mass will be over the area but with clouds and rain chances, highs will be slightly cooler on Tuesday with highs in the middle to upper 70s. The warmer readings will be across the eastern Ozarks will lower rain chances and clouds will occur.
Mid-upper ridging is building and heights are becoming anomalously positive. This signals a warmer pattern.
The low level circulation of Norma is currently drifting in the Gulf of California while the mid-level circulation has sheared off and is beginning to drift northeastward through Mexico. Aligning with the PWATs, the lower Trans Pecos, southeastern Permian Basin, and western low- rolling Plains will see the most rainfall accumulations today (1-2" likely), with a fairly sharp cut-off moving west as Midland/Odessa should see only around 0. With some short-lived subsidence as Norma's remnants depart, the day on Tuesday looks fairly quiet before a large upper trough swings through Tuesday night. Have undercut NBM some, leaving many spots in the low to mid 70s for today's highs. A warmer day is on tap for Tuesday thanks to no precipitation and much less cloud cover, allowing widespread highs in the upper 70s and low 80s.
Besides the Winter Storm Warnings along the Divide (where we had the highest confidence), we issued additional Winter Storm Watches for the remainder of western Montana.
1003 PM EDT Mon Oct 23 2023 High pressure will remain in place through the rest of the week with dry conditions prevailing.
