1250 AM EST Thu Nov 14 2024 (Rest of today through Thursday) Generally benign weather conditions forecast for today as a cold front drifts south of our region towards the Florida Straits. High temps today will be in the low to mid 80s across the east coast metro and around the lake region, to upper 80s over SW FL. Dewpoints in the low to middle 60s will make it a very pleasant day. Afternoon high temps will be in the low to mid 80s.
1015 PM CST Wed Nov 13 2024 The mid-evening sfc analysis indicates that our cold front continues to make steady Ewd progress across the region, and extends from just E of a AGO, to E of a MNE, to 3F3, to near a JAS and W of a BOT line of of 04Z. However, webcams from the LA Mesonet stations at ULM and Colfax and LA DOTD still maintain some FG in place attm, although the more dense FG noted on satellite imagery remains E of these areas, but winds with the front should quickly disperse the FG across the Ern zones by/shortly after midnight, as cooler and much drier air advects E with the fropa. 15 (00Z TAFS) High pressure is quickly influencing the local terminals this evening as SKC will remain in place overnight.
257 AM EST Thu Nov 14 2024 Today will see increasing clouds as high pressure pushes east of the region.
1033 PM MST Wed Nov 13 2024 - Dry conditons with mainly warmer temperatures for Thursday.
The U/L pattern continues to be progressive across the CONUS with an U/L disturbance over the Ohio River Valley with the trough axis extending to the north central Gulf of Mexico. with another significant trough pushing onshore the west coast of the U.
Instability associated with an approaching upper trough near the coast will initiate a round of afternoon showers in SE Oregon and far SW Idaho by Thursday afternoon.
1051 PM CST Wed Nov 13 2024 The mid-evening sfc analysis indicates that our cold front continues to make steady Ewd progress across the region, and extends from just E of a AGO, to E of a MNE, to 3F3, to near a JAS and W of a BOT line of of 04Z.

1101 PM CST Wed Nov 13 2024 (This evening through Thursday Night) Today's dry cold front is currently moving through portions of the Brazos Valley, and should push offshore late tonight. This will usher in cooler and drier conditions, with lows for tonight/Thursday morning in the mid 40s/mid 50s inland and upper 50s/60s along the coast.
458 AM CST Thu Nov 14 2024 (Today through Friday) Key Message: - Minor coastal flooding remains a high concern during high tide through this weekend, especially from the afternoon to evening hours The cold front has now entirely passed through South Texas with much drier air filtering in its wake as dewpoints drop into the 30s and 40s. Our most northern locations have been under clear skies and efficient radiational cooling, allowing temperatures to drop into the low 50s.
545 AM CST Thu Nov 14 2024 (Today through Friday) A cold front with a leading warm front is currently sliding through the area this morning. There is some limited instability right along the warm front, so there has been some some thunder, albeit isolated activity. Thunder will remain a plausible scenario until the cold front passes through.
But, the additional snow showers through this evening will still be most numerous for the southern Oregon Cascades and the back country higher elevations of western Siskiyou County with new accumulations of 1 to 4 inches, except around 6 inches on the high peaks.
547 AM CST Thu Nov 14 2024 (12Z TAFS) VFR conditions have quickly developed across the area in the wake of a passing cold front. (Now through Friday) Cooler and drier conditions are on the way as a cold front is currently progressing across the area. A large upper level low is currently moving across Illinois and lifting into the Great Lakes driving a surface cold front across the southeastern US. In the fronts wake, a significantly cooler and drier airmass will move in as dewpoints have already dropped nearly 10 degrees across areas west of I-65. You will likely not notice the cooler temperatures until tonight when temperatures drop into the 40s to low 50s. Expect this to continue into Friday and Friday night as northwesterly flow on the backside of the upper low continues to drive continental air southward.
Utah and southwest Wyoming will see dry, increasingly breezy, and unseasonably warm conditions ahead of an approaching trough.
Upper level ridging continues to manifest over the region, and winds revert back from the southwest tonight.
A cool airmass in place will limit afternoon highs to the upper 60s to lower 70s with lows tonight in the lower 40s. Cool temperatures to continue into Friday with highs ranging from the mid 60s to the lower 70s. With upper-level ridging to prevail aloft through the short term period, expect stable conditions with skies remaining mostly clear through Friday.
An upper-level trough will influence the weather over the next couple days, with isolated to scattered showers today through Friday. Today, precipitation will fall in the form of snow above roughly 4000-4500 ft, while the lower elevations will see rain showers. Some weak instability will facilitate isolated showers for the lower elevations. The trough axis will swing across the PacNW on Friday, ushering in cooler temperatures and an end to showers by Friday evening and Friday night as the trough to the east.
(Today through Friday) A cold front with a leading warm front is currently sliding through the area this morning. There is some limited instability right along the warm front, so there has been some some thunder, albeit isolated activity. Thunder will remain a plausible scenario until the cold front passes through.
(Today through Friday) Key Message: - Minor coastal flooding remains a high concern during high tide through this weekend, especially from the afternoon to evening hours The cold front has now entirely passed through South Texas with much drier air filtering in its wake as dewpoints drop into the 30s and 40s. Our most northern locations have been under clear skies and efficient radiational cooling, allowing temperatures to drop into the low 50s.
(Today) Light/moderate showers, along with perhaps a few embedded tstms, continue to move eastward across the mid TN Valley heading into the overnight hrs, as a cold front approaches the MS River. Cloud cover though may be slow to diminish for much of the day, as an upper low/trough pattern translates east over the OH Valley/mid Atlantic states. Cooler/drier air will at least begin to spread into the area from the WNW in the wake of the frontal passage, with highs struggling to surpass the lower/mid 60s.
The U/L pattern continues to be progressive across the CONUS with an U/L disturbance over the Ohio River Valley with the trough axis extending to the north central Gulf of Mexico. with another significant trough pushing onshore the west coast of the U. The disturbance over the Ohio River Valley will push offshore the mid Atlantic coast on Friday, with the west coast trough digging over the inter-mountain west and extending south to off the Baja California coast.
Cooler temperatures are expected today and Friday, and more rain is forecast this weekend. Post frontal convective showers continue to drift onshore early this morning as an upper trough digs southward down the West Coast. As the coldest portion of the low passes overhead this afternoon, instability may be deep enough to support some thunderstorms. Shower activity is then forecast to quickly weaken tonight and early Friday from south to north as flow turns northerly behind this passing trough. Lows are forecast to reach the mid 20s in Trinity county and the low 30s elsewhere, with frost devleopment possible along the coast.
The forecast area remains in an active pattern as troughing elongates and sweeps over Northern CA today through early Friday, continuing periods of light to moderate snow, light rain, and breezy winds.
(Today through Friday) A cold front will clear the area around sunrise today and usher in some nice cool dry air.
632 AM EST Thu Nov 14 2024 A mid level trough will move east, then southeast across the Great Lakes and Ohio Valley through tonight. High pressure will begin to build in from the west on Friday. This high will then influence the area's weather into the weekend.
929 AM EST Thu Nov 14 2024 A mid level trough will move east, then southeast across the Great Lakes and Ohio Valley through tonight. High pressure will begin to build in from the west on Friday. This high will then influence the area's weather into the weekend.
(Now through Friday) Cooler and drier conditions are on the way as a cold front is currently progressing across the area. A large upper level low is currently moving across Illinois and lifting into the Great Lakes driving a surface cold front across the southeastern US. In the fronts wake, a significantly cooler and drier airmass will move in as dewpoints have already dropped nearly 10 degrees across areas west of I-65. You will likely not notice the cooler temperatures until tonight when temperatures drop into the 40s to low 50s. Expect this to continue into Friday and Friday night as northwesterly flow on the backside of the upper low continues to drive continental air southward.
535 AM CST Thu Nov 14 2024 (Today) Light/moderate showers, along with perhaps a few embedded tstms, continue to move eastward across the mid TN Valley heading into the overnight hrs, as a cold front approaches the MS River. Cloud cover though may be slow to diminish for much of the day, as an upper low/trough pattern translates east over the OH Valley/mid Atlantic states. Cooler/drier air will at least begin to spread into the area from the WNW in the wake of the frontal passage, with highs struggling to surpass the lower/mid 60s.
(Today through Friday Night) Latest surface and upper air data indicate upper level low pressure is located over west central Illinois and its associated cold front now well east of the forecast area. Otherwise, clear skies abound and will remain in place through the forecast period as high pressure, both on the surface and aloft, move into and eventually settle over the forecast area.
A low pressure system from the northwest will bring stronger and gusty west winds for late tonight and Friday with the stronger gusts for the mountains and deserts to 35 to 45 mph.
A longwave trough associated with mid-level low pressure over the central United States will eventually slide east tonight into early Friday, pushing a decaying surface frontal boundary across the state on Friday. Temperatures this afternoon could be a few degrees cooler, except for inland Southwest Florida where mid to upper 80s are forecast, compared to previous days. Overnight lowers will range from the mid to upper 60s inland to the lower to mid 70s along the coast.
Above normal temperatures and sunny skies are expected as high pressure remains in control for one more day. Afternoon highs look to be about 5-10F above normal, with temperatures in the mid 50s F to mid 60s F in the High Country and in the 70s F to near 80F in the lower elevations.
529 AM CST Thu Nov 14 2024 (Today through Friday Night) Latest surface and upper air data indicate upper level low pressure is located over west central Illinois and its associated cold front now well east of the forecast area. Otherwise, clear skies abound and will remain in place through the forecast period as high pressure, both on the surface and aloft, move into and eventually settle over the forecast area.
337 PM EST Thu Nov 14 2024 Low pressure finally exits late Friday into Friday night. High pressure returns late Friday night into the early part of the weekend.
At the surface, sfc ridging was centered across Central Texas into the Upper/Middle Red River Valley Central Oklahoma late this morning with this feature expected to shift slowly eastward into tonight. A cool airmass in place will limit afternoon highs to the upper 60s to lower 70s with lows tonight in the lower 40s. Cool temperatures to continue into Friday with highs ranging from the mid 60s to the lower 70s. With upper-level ridging to prevail aloft through the short term period, expect stable conditions with skies remaining mostly clear through Friday.
Friday and the weekend will see an increasingly amplified pattern aloft as a trof digs into the Rockies resulting in a ridge axis across the eastern CONUS.
The upper low responsible for the rain and cold front will continue to track east off the Atlantic Coast, and ridging will build over the area as we head into the weekend. Large scale subsidence will promote dry weather through tomorrow, with cooler temperatures as highs will be limited to the 60s. The main question will be how much cloud cover develops as a result of wrap-around moisture tied to the aforementioned upper low, and if the winds will calm enough to support fog development. Otherwise, overnight lows will be a bit cooler dropping into the 40s.
High pressure centered across the Northeast is still maintaining its grip on the Florida Keys and surrounding coastal waters, although it has loosened it slightly over the past 12 hours. Temperatures are in the lower 80s and dew points are sitting right around 70 degrees, making for quite a pleasant mid-November morning. A low pressure system currently moving across the Ohio Valley is forecast to aid in the development in a new low off the Carolina coast later this afternoon or evening, which will help erode the high in the Northeast and cause winds to slacken further. High pressure centered over the Northeast U. Low pressure moving across the Ohio Valley will transfer its energy to the coast this afternoon and this evening. As a result, a new area of low pressure will develop and strengthen off North Carolina.
Friday will see similar conditions to those of today with highs generally in the 70s everywhere except the warmer Rio Grande Plains. Southeasterly wind increases over the southern Edwards Plateau late morning tomorrow ahead of a deepening trough over the western US with lighter wind elsewhere.
Bumped high temperatures up a 2-3 degrees across most of the region, but we will likely still remain in the low to middle 60s.
(Rest of Today) Clouds will clear from W to E over the next several hours in the wake of a cold front pushing across the area this morning.
High pressure and a drier airmass will then build into the area as we head into the weekend. Highs on Friday will be in the low to mid 50s with lows Friday night in the upper 30s to lower 40s.
A Freeze Warning has been issued for the four far northwest Arkansas counties, leveraging not only the official forecast but also higher NBM probabilities for freezing temperatures there.
The primary feature responsible for this will be longwave troughing that extends over the FL peninsula from a closed low over the Ohio Valley. As this low moves over the eastern seaboard and the Atlantic on Friday, it will drag a weakening cold front across Southeast US and FL peninsula, pushing through South FL during the afternoon and evening. Highs today will be in the low to mid 80s, with tonight's lows in the mid to upper 60s. Highs on Friday will again reach the low to mid 80s before the front moves through and starts to cool things off.
159 PM CST Thu Nov 14 2024 - Mostly dry conditions and warmer temperatures (high temperatures 10 to 15 degrees above normal).
Southwest breezes will pick up mid to late afternoon as our next trough approaches, but gusts should be 20 mph or less for most of us. Above normal temperatures and sunny skies are expected as high pressure remains in control for one more day. Afternoon highs look to be about 5-10F above normal, with temperatures in the mid 50s F to mid 60s F in the High Country and in the 70s F to near 80F in the lower elevations.
An upper-level trough off the Pacific Northwest coast this morning is still expected to move inland this evening, passing across the forecast area from Friday through Friday night. On Friday morning, light snowfall may occur across southwest Oregon with the trough's passage. Ensemble models consistently show an upper-level low forming over northeast Nevada and south- central Idaho by Friday afternoon and evening, creating favorable conditions for a precipitation band to form on the low's backside.
Temperatures have crept up into the lower to mid 80s, and dew points are in the upper 60s to near 70 degrees. The influence of the high over the Northeast has gradually waned over the day, and winds have decreased a few knots in response. A developing low off the Carolina coast will help erode the high further, allowing for a more noticeable decrease in winds overnight tonight. High pressure will build back in behind the front and tighten the gradient once again.
(Through Friday) A cold front is moving through the area this afternoon with only light showers along and ahead of the front. Behind the front, cooler air will arrive on northwesterly winds. Temperatures tonight will be in the lower to middle 50s for most of the area with upper 40s in our far northwest areas. Mainly sunny skies are expected on Friday as high pressure builds in with highs in the upper 60s to middle 70s.
/96 (Now through Friday) Cooler and drier conditions are on the way as a cold front is currently progressing across the area. A large upper level low is currently moving across Illinois and lifting into the Great Lakes driving a surface cold front across the southeastern US. In the fronts wake, a significantly cooler and drier airmass will move in as dewpoints have already dropped nearly 10 degrees across areas west of I-65. You will likely not notice the cooler temperatures until tonight when temperatures drop into the 40s to low 50s. Expect this to continue into Friday and Friday night as northwesterly flow on the backside of the upper low continues to drive continental air southward.
As a high pressure sets up over the region tomorrow, dry weather will follow and temperatures will warm through the weekend.
338 PM EST Thu Nov 14 2024 Widespread rain will become more scattered this afternoon and diminish overnight as low pressure crosses. Overall probability is low, though highest probabilities are northwest of Pittsburgh and across the ridges with upsloping.
1131 AM CST Thu Nov 14 2024 (Today through Friday Night) Latest surface and upper air data indicate upper level low pressure is located over west central Illinois and its associated cold front now well east of the forecast area. Otherwise, clear skies abound and will remain in place through the forecast period as high pressure, both on the surface and aloft, move into and eventually settle over the forecast area.
1106 AM CST Thu Nov 14 2024 (Today through Friday) Key Message: - Minor coastal flooding remains a high concern during high tide through this weekend, especially from the afternoon to evening hours The cold front has now entirely passed through South Texas with much drier air filtering in its wake as dewpoints drop into the 30s and 40s.

119 PM EST Thu Nov 14 2024 Rain will continue over the area this afternoon and evening ahead of an approaching cold front. Key Message(s): - Rain, overcast skies and cool temps today, clearing tonight Moisture advection over surface ridging will promote wedge conditions over the region today. We expect warmer temps in areas to the south and east where there may be some cloud breaks and less rain but highs should still be below normal. Tonight, clouds should gradually clear as dry air pushes in and downslope flow aids in drying out the low-levels. Closed upper low will be moving off the east coast during the day Friday, taking the associated surface cold front out to sea with it.
324 PM EST Thu Nov 14 2024 Low pressure finally exits late Friday into Friday night. High pressure returns late Friday night into the early part of the weekend.
Efficient radiational cooling will help promote cooler overnight temperatures tonight followed by warmer lows tomorrow night as onshore flow returns advecting warmer air inland. Overnight lows tonight range in the mid 40s north to the low to mid 50s from the Coastal Bend to the Brush Country and mid 60s on the island.
1241 PM EST Thu Nov 14 2024 A mid level trough will move east, then southeast across the Great Lakes and Ohio Valley through tonight. High pressure will begin to build in from the west on Friday. This high will then influence the area's weather into the weekend.
250 PM EST Thu Nov 14 2024 (This afternoon through Friday) Surface analysis shows a cold front across far NW GA with a wedge still in place across far NE GA. High pressure, cooler temperatures and dry conditions will build in behind the exiting frontal boundary.
(This evening through Friday night) Upper troughing that brought yesterday's strong to severe storms extended from the western Great Lakes to the Carolinas this afternoon, with ridging across the Great Plains. Yesterday's cold front extended from the eastern Florida Panhandle to the central Gulf of Mexico with high pressure centered over Texas.
252 PM EST Thu Nov 14 2024 Rain will continue over the area this afternoon and evening ahead of an approaching cold front. Key Message(s): - Rain, overcast skies and cool temps today, clearing tonight Moisture advection over surface ridging will promote wedge conditions over the region today.

Tonight, clouds should gradually clear as dry air pushes in and downslope flow aids in drying out the low-levels. Closed upper low will be moving off the east coast during the day Friday, taking the associated surface cold front out to sea with it.
We're transitioning to the backside of the upper trough, with weak northwest flow advecting cool 850 temperatures around and over us through the short term.
1158 AM CST Thu Nov 14 2024 (Rest of Today) Clouds will clear from W to E over the next several hours in the wake of a cold front pushing across the area this morning.
1114 AM CST Thu Nov 14 2024 - Warmer temperatures expected Friday into the weekend.
Widespread showers continue today in onshore flow with a trough axis just offshore. There should be a decrease in coverage overnight into Friday morning as the trough moves inland, though some will continue focused near the Cascades, the Cascade Foothills, the Siskiyous and over by the Warner Mtns.
Issued by National Weather Service Huntsville AL 1209 PM CST Thu Nov 14 2024 (Today through Friday) A cold front with a leading warm front is currently sliding through the area this morning. There is some limited instability right along the warm front, so there has been some some thunder, albeit isolated activity. Thunder will remain a plausible scenario until the cold front passes through.
