559 PM EST Fri Nov 8 2024 (This afternoon through Saturday) Pleasant and warm weather is expected across South Florida to end the work week and start the weekend thanks to mid-level ridging hanging over the region. The ridge will usher in a generally dry and warm airmass (12Z sounding PWAT 1. High temperatures will be in the mid to upper 80s each day, with heat indices in the low 90s. Tonight's lows will range from the low 70s over the interior and Gulf Coast, with mid 70s across the East Coast metro.
934 PM EST Fri Nov 8 2024 Gradually increasing clouds but still dry weather will dominate the first part of the weekend as high pressure passes through the lower Great Lakes and Mid Ohio Valley.
917 PM EST Fri Nov 8 2024 A mainly dry cold front will move through tonight bringing cooler and drier conditions for the weekend as high pressure briefly builds in from the north.
Expect chilly to cold morning low temperatures and patchy frost in the lower elevations and valleys, otherwise it'll be milder at elevation in the hills and mountains this morning. (This evening through Saturday) Dry weather will prevail tonight and tomorrow due to high pressure sitting over the West. Tomorrow, another dry day is on tap, though high temperatures look to be a few degrees cooler than Friday.
747 PM CST Fri Nov 8 2024 Satellite imagery this evening shows a potent low and its cold front near the OK Panhandle. Ahead of this cold front, showers and a few thunderstorms are slowly making their way eastward with activity stretching as far east as AR and LA at this time. (Rest of today through Saturday) A surface boundary between high pressure to our N and a cold front to our S has been streaming low clouds and drizzle over Middle TN this morning. Depending on how fast these clouds can move out, highs today should climb into the low 70s. Overnight lows will be slightly cooler in the low 50s, even upper 40s possible across our TN/KY bordering counties and the Upper Cumberland.
605 PM CST Fri Nov 8 2024 (Remainder of today and tonight) Low clouds persist across the Tennessee Valley above the shallow cool pool brought in from last nightâs weak cold front. The HRRR indicates weak NE flow along the surface from the previously mentioned front will bring slightly cooler, drier air overnight.
Weakening high pressure will maintain dry conditions through tonight.
623 PM EST Fri Nov 8 2024 Gradually increasing clouds but still dry weather will dominate the first part of the weekend as high pressure passes through the lower Great Lakes and Mid Ohio Valley.
A cold front to the west along with Rafael to the south is producing a convergent zone evident on satellite. Tropical deep layer moisture revealed in TPW satellite imagery is pooling over the northwest Gulf of Mexico, where it is poised to surge north ahead of an approaching closed low approaching the MS valley.
537 PM CST Fri Nov 8 2024 Mild and wet weather will continue this weekend as a cold front tracks across the region. Another cold front will move through midweek with chances for showers followed by more seasonable temperatures to finish the week.
Cooler marine weather will move in this weekend with possible coastal drizzle.
GOES water vapor imagery shows a large, maturing upper low pushing off the central high Plains early this morning. This will be quickly overcome as lift and moisture increase ahead of the approaching upper low. Hires models have trended slightly faster with the cessation of primary rainfall this afternoon as a dry slot wraps around the southern periphery of the upper low.
349 AM EST Sat Nov 9 2024 A weak cold front will move through the area this morning.
(Tonight) Clouds pouring out from the low pressure system lifting into the Plains will reach the TN Valley throughout the night.
1046 PM CST Fri Nov 8 2024 Satellite imagery this evening shows a potent low and its cold front near the OK Panhandle.

Currently - A fairly small scale weak ridge has nosed westward from the Bahamas and Cuba into Florida and the Keys. This ridge sits between Hurricane Rafael creeping westward through the central Gulf of Mexico and an inverted trough near the Greater Antilles. This ridge is maintaining gentle to moderate easterly breezes across the Keys this evening. Deep layered ridging is in place and copious dry air has moved in from the lower levels up. Drier air is showing up at the surface with dew points now in the lower 70s. With that said, overnight lows will settle broadly in the mid to upper 70s with dew points remaining in the lower 70s.
ARS Mild and wet weather will continue this weekend as a cold front tracks across the region. Another cold front will move through midweek with chances for showers followed by more seasonable temperatures to finish the week.
A mix of light rain, snow, and freezing rain will occur tonight into Saturday morning in Natrona County.
Discussion: In the upper levels, the ridge over the Southeast will remain in place today. A trough will move into the Mid and Lower Mississippi Valleys tonight as a closed low spins near MN/IA. At the surface, high pressure will remain over the East Coast as a frontal system stalls near West Tennessee with an occluded front stretching to the vertically stacked low moving from the Great Plains into the Upper Midwest. Highs will be above normal again today in the lower to mid 70s. HREF 850mb winds keeps the low level jet west of the mountains and shows about 30 knots near the mountains from a southerly or southwesterly direction.
Looking at IR imagery there is a very distinct large potent low pressure system moving across eastern Colorado. However, one area to monitor will be across far southeastern Natrona County in the higher elevations of Casper Mountain. This area may see a brief period of freezing drizzle during the morning hours today. There is not much concern with this but it may create some slick spots in the area especially in the higher elevation areas.
103 AM EST Sat Nov 9 2024 (Through Saturday) Upper ridging will prevail through the near term as a large upper low treks northeast across the central plains. Generally east- southeasterly flow as a result of high pressure centered over the great lakes will continue gradually pumping more robust tropical moisture across the region as Rafael churns to the south of us.
1254 AM EST Sat Nov 9 2024 A mainly dry cold front will move through tonight bringing cooler and drier conditions for the weekend as high pressure briefly builds in from the north.
Expect chilly to cold morning low temperatures and patchy frost in the lower elevations and valleys, otherwise it'll be milder at elevation in the hills and mountains this morning. The exception to this is at the higher elevations where temperatures are either the same or slightly warmer. (This evening through Saturday) Dry weather will prevail tonight and tomorrow due to high pressure sitting over the West. Tomorrow, another dry day is on tap, though high temperatures look to be a few degrees cooler than Friday.
1000 PM CST Fri Nov 8 2024 (Tonight) Clouds pouring out from the low pressure system lifting into the Plains will reach the TN Valley throughout the night.
Given the convective inhibition associated with a ridge, this boundary will have a hard time producing showers. As a trough lifts north, to our west across Mississippi and Alabama, some brief light showers could pop up across our SE Alabama and Florida Panhandle counties tonight. Expect daytime highs generally in the low to mid 80s with overnight lows generally in the upper 60s.
1226 AM EST Sat Nov 9 2024 Gradually increasing clouds but still dry weather will dominate the first part of the weekend as high pressure passes through the lower Great Lakes and Mid Ohio Valley.
(Today) The surface map shows a nearly stacked low pressure system centered over west central KS and southeast CO, with an occluded front draped southeast into eastern TX. A deep layer ridge axis was situated from the upper Midwest south through the southeast U. As the low lifts northeast into NE today, a warm/moist conveyor belt will become situated along and just west of the MS River. Clouds and precipitation will keep high temperatures in the lower 70s for most valley areas, with upper 60s atop the higher Cumberland Plateau locations.
Updated at 207 AM CST Sat Nov 9 2024 - Quiet weather ahead with near to warmer than normal temperatures through the forecast period. Expect sunny skies and warmer temperatures today. The upper level low currently situated north of our region will push northeastward towards the Great Lakes region bringing zonal flow aloft by the end of the day.
As of early this morning, a stout, vertically stacked extratropical cyclone was meandering across western Kansas and eastern Colorado. This is bringing scattered rain and snow showers across the High Plains along with a large band of showers stretching across much of Nebraska into eastern Kansas and western Missouri.
(Today through Sunday) The most recent surface analysis from the Weather Prediction Center indicates a cold front over the southeast corner of Deep South Texas and the Rio Grande Valley, with isolated showers noted across the BRO CWFA on KBRO Doppler radar. Some additional isolated convection remains possible through today as the front transitions into the western Gulf of Mexico, with dry weather on tap tonight and through Sunday as the front becomes more stationary but weak 500 mb ridging nudges in from the south. Swell from Tropical Cyclone Rafael will continue to approach the Lower Texas Coast through the weekend.
High pressure will bring quiet and dry weather through the weekend.
(Today through Sunday Night) The cold front has made it through the majority of SE Texas and is currently on a SW-NE orientation from the Gulf Waters through Liberty County. Lows for tonight and Sunday night will be cooler courtesy of continued northerly flow. Sunday should feature partly cloudy skies and slightly warmer temperatures as highs get into the upper 70s to mid 80s.
558 AM CST Sat Nov 9 2024 (Today through Sunday) High pressure will move east of the Appalachians today, with a low pressure over the northern plains bringing a frontal boundary towards the MS River Valley. East to southeasterly flow will prevail in the low and mid levels around this high pressure, with plenty of moisture advection to the state through the short term. Overnight tonight, a mid level jet will move through the state as the high pressure weakens and moves off the east coast. Temperatures will be hovering between 60 and 80 between the highs and lows through Sunday, with values well above normal for this time of year.
A big upper low is centered over eastern Colorado and western Kansas. Precipitation, mostly in the form of rain, is moving around the upper low. The upper low will become centered over Nebraska this afternoon. The upper low will move to the east of the region on Sunday. Low temperatures Sunday night will be similar or slightly cooler than the previous night.
Winds are from the east thanks to a high pressure gradually moving into the Eastern Seaboard. This feature will pivot around a low level ridge in association with the aforementioned ridge. The act of the weak tropical wave moving in in combination with the high sliding further east across the Atlantic will lead to a slackening of the pressure gradient and a discontinuation of breezy conditions. Strong high pressure moving across the Great Lakes region will settle into the Northeast U.
Today will be another pleasant fall day with high temperatures running about five to ten degrees warmer than yesterday depending on location. The warming trend is thanks to mid-level ridging building in the wake of the strong cutoff low which previously migrated through the area.
(Today through Sunday Night) To begin the period, an upper level low is located across Rockies and moving into the Central Plains.
925 AM EST Sat Nov 9 2024 In the wake of the exiting back-door cold front, high pressure will build into the area from the north.
257 AM MST Sat Nov 9 2024 - Upper low will bring widespread precipitation to much of western South Dakota and parts of northeastern Wyoming today through this evening.
Temperatures in the mid 70s areawide, dewpoints mainly in the lower 70s. Gradual decreasing risk levels around the High risk lowers to Marginal Risk over Lower Acadiana. Due to the higher risk shifting southwest, expanded the Flood Watch to include all of Southeast Texas.
At the upper levels, weak ridging will remain over the area through the end of the weekend. Temps this weekend will remain above normal, with highs in the low to mid 80s across the east coast metro, and upper 80s across SW FL. Low temps tonight will range from the lower 70s around the lake and in SW FL, to mid and upper 70s across the east coast metro.
530 AM CST Sat Nov 9 2024 (Today through Sunday Night) To begin the period, an upper level low is located across Rockies and moving into the Central Plains.
409 AM CST Sat Nov 9 2024 The stalled boundary has drifted southward and now sits around the Highway 84 corridor.
Active pattern continues with a shift towards cooler temps and increased moisture. All hope is not lost, however, and your hands will see some relief later today! A weak trough is progged to move through the region by this evening into tonight. This weak trough becomes cut off and rather insignificant pretty quickly as the next more robust system moves in.
527 AM CST Sat Nov 9 2024 The stalled boundary has drifted southward and now sits around the Highway 84 corridor.
A front to the west, an upper level ridge east, and TS Rafael south. For today, there will be a tight gradient for POPs across our region from west to east with the highest percentage of precip residing along and west of the I-55 corridor. As for temps over the weekend it still looks to be above average, especially where POPs are the lowest.
An upper level, closed low pressure system moving northeast from the southern Rockies will increase clouds this morning and afternoon with rain showers to follow. Global and high res models also hint at a dry slot reaching around the north side of the low, bringing a brief break to precipitation across the area after the initial round.
632 AM EST Sat Nov 9 2024 A weak cold front will move through the area this morning. Strong high pressure New England will build south through the Carolinas into Georgia into Sunday. Scattered light rain or drizzle expected Sunday with cooler temperatures.
220 AM MST Sat Nov 9 2024 - Mainly warmer and dry conditions for most areas through the weekend. High pressure over the region will maintain warm and dry conditions for most of the area today. An upper low lifting out of Colorado and into Nebraska brings a low chance (20% or less) for rain across far southeast Carter County, with the probability of 0. High temperatures in the 50s to lower 60s can be expected today, with slightly cooler conditions for Sunda.
The parent upper low in the long wave is lifting over KN and into NB today. However, the cyclone is moving W/NW at 5KT and will help to keep a rich moisture feed riding up along the front. High pressure will eventually move into our area, but this first front will stall and reinforcements will arrive with a larger air mass to start the new week.
GOES water vapor imagery shows a large, maturing upper low pushing off the central high Plains early this morning. This will be quickly overcome as lift and moisture increase ahead of the approaching upper low. Hires models have trended slightly faster with the cessation of primary rainfall this afternoon as a dry slot wraps around the southern periphery of the upper low. Upper low is sluggish to depart Sunday as it becomes vertically stacked and deamplifies. A decaying mid-level deformation zone will keep light rain chances (40-70%) over the northern half of the forecast area Sunday morning with the highest chances near the MN border.
623 AM EST Sat Nov 9 2024 In the wake of the exiting back-door cold front, high pressure will build into the area from the north.
422 AM MST Sat Nov 9 2024 - Upper low will bring widespread precipitation to much of western South Dakota and parts of northeastern Wyoming today through this evening.
525 AM CST Sat Nov 9 2024 (Today through Sunday Night) The cold front has made it through the majority of SE Texas and is currently on a SW-NE orientation from the Gulf Waters through Liberty County. Lows for tonight and Sunday night will be cooler courtesy of continued northerly flow. Sunday should feature partly cloudy skies and slightly warmer temperatures as highs get into the upper 70s to mid 80s.
An active fall weather pattern will take shape through the week as multiple systems push through the Desert Southwest, which will result in occasional breezy and cooler conditions as well as an increased chance of precipitation.
353 AM CST Sat Nov 9 2024 (Today) The surface map shows a nearly stacked low pressure system centered over west central KS and southeast CO, with an occluded front draped southeast into eastern TX. A deep layer ridge axis was situated from the upper Midwest south through the southeast U. As the low lifts northeast into NE today, a warm/moist conveyor belt will become situated along and just west of the MS River. Clouds and precipitation will keep high temperatures in the lower 70s for most valley areas, with upper 60s atop the higher Cumberland Plateau locations.
Looking at IR imagery there is a very distinct large potent low pressure system moving across eastern Colorado. However, one area to monitor will be across far southeastern Natrona County in the higher elevations of Casper Mountain. This area may see a brief period of freezing drizzle during the morning hours today. There is not much concern with this, but it may create some slick spots in the area especially in the higher elevation areas. This is due to predominately westerly and southwesterly flow developing across the region ahead of a deep trough that begins to move into the PACNW.
535 AM CST Sat Nov 9 2024 (Today through Sunday) The most recent surface analysis from the Weather Prediction Center indicates a cold front over the southeast corner of Deep South Texas and the Rio Grande Valley, with isolated showers noted across the BRO CWFA on KBRO Doppler radar. Some additional isolated convection remains possible through today as the front transitions into the western Gulf of Mexico, with dry weather on tap tonight and through Sunday as the front becomes more stationary but weak 500 mb ridging nudges in from the south. Swell from Tropical Cyclone Rafael will continue to approach the Lower Texas Coast through the weekend.
High pressure will bring gradually warming temperatures to the region through the weekend.
541 AM CST Sat Nov 9 2024 (Today through Sunday) The cold front that moved across the local area during the day and evening yesterday is now exiting the middle Texas coast. In the wake of the frontal boundary, a cooler airmass has been spreading across south central Texas for the last 18 hours or so. Overnight lows are expected to drop down to the lower to mid 40s across the southern Edwards Plateau and western Hill Country while the rest of the local area reaches the upper 40s to lower 60s across the coastal Plains. The Nighttime Microphysics satellite channel shows cloudy skies across the eastern two-thirds of south central Texas between 3kf and 4kf just above the shallow cooler airmass.
525 AM CST Sat Nov 9 2024 Updated at 523 AM CST Sat Nov 9 2024 - Quiet weather ahead with near to warmer than normal temperatures through the forecast period. Expect sunny skies and warmer temperatures today. The upper level low currently situated north of our region will push northeastward towards the Great Lakes region bringing zonal flow aloft by the end of the day.
(Tonight through Sunday night) Key Messages: - Hazardous marine conditions and coastal hazards continue A drier airmass is expected to remain in place in the wake of the cold front throughout the short term with PWAT values remaining near 1", which is just a tick below the the 50% percentile for this time of the year. A mid to upper level ridge is expected to begin building into the region tomorrow which will increase subsidence across the region. With the increased swell periods hanging around tonight, continued the high risk of rip currents through tomorrow night.
Northern Michigan centered squarely under upper level ridge of that southern stream, maintaining the dry and seasonably mild conditions. the beginning stages of high level moisture advection well ahead of closed upper level low rotating northeast into the central Plains. This low and its attendant weaker surface reflection will continue to work northeast, cutting across the Northwoods later Sunday. Details: Top-down saturation will continue tonight as upstream low pressure works its way northeast. Scattered to numerous showers expected to continue through Sunday as low pressure works right overhead. with highs on Sunday mostly in the lower and middle 50s.
1152 AM CST Sat Nov 9 2024 (Today through Sunday) The cold front that moved across the local area during the day and evening yesterday is now exiting the middle Texas coast. In the wake of the frontal boundary, a cooler airmass has been spreading across south central Texas for the last 18 hours or so. Overnight lows are expected to drop down to the lower to mid 40s across the southern Edwards Plateau and western Hill Country while the rest of the local area reaches the upper 40s to lower 60s across the coastal Plains. The Nighttime Microphysics satellite channel shows cloudy skies across the eastern two-thirds of south central Texas between 3kf and 4kf just above the shallow cooler airmass.
(Rest of today through Sunday) A breezy easterly to southeasterly wind flow will continue through the weekend as South Florida sits on the periphery of high pressure centered over the mid-Atlantic United States. A pocket of drier air accompanying a ridge of high pressure aloft will help limit the depth of convection which should remain isolated Atlantic showers that survive ashore. Temperatures along the Atlantic coast should remain in the lower to mid 80s but additional sunshine helping to warm the easterly airmass as it traverses the peninsula will allow Southwest Florida to warm into the mid to upper 80s each afternoon.
