(Wednesday through Thursday) Quiet weather is coming to an end, as another trough and cold front look to move through the region on Thursday. However, ahead of this trough, a stationary front to our south will begin to pull back north in the form of a warm front. However, the prospects of severe weather will heavily depend on how far north this warm front gets. At this time, overall thinking is that this warm front will only sneak into our far southern zones, with the best severe weather environment just below that. All modes of severe weather will be possible on Thursday, including tornadoes, particularly south of the warm front in the slight/enhanced risks. In the event that it looks like the warm front will end up farther north, adjustments to the current SPC outlook will certainly follow.
645 AM EST Wed Nov 29 2023 High pressure builds into the area and remains in place through Thursday.
302 AM CST Wed Nov 29 2023 - Temperatures will be on the warmer side of our seasonal values for the remainder of the week.
519 AM CST Wed Nov 29 2023 (Today and tonight) Currently we have weak upper level ridging over the area, with an upper low off the northern California coast. This low will move southeast into the southwestern U. As the low approaches, surface pressure falls will impact the southern plains, increasing southerly flow and moisture in our area. Lift will increase tonight as the low approaches, and we could see a few showers across areas mainly east of an Abilene to Sonora line. Tonight, with mostly cloudy skies and increased moisture, lows will be much warmer in the mid 40s to lower 50s.
732 AM EST Wed Nov 29 2023 Single digit wind chill values this morning will quickly warm toward above normal temperature by Thursday under the influence of high pressure.
346 AM CST Wed Nov 29 2023 (Issued 346 AM CST Wed Nov 29 2023) Today and Tonight: Expect sunny skies today with warmer temperatures. Highs will be in the upper 30s to around 40 thanks to low level warm air advection and a brief high pressure ridge tracking overhead. Tonight will be milder with lows in the mid to upper 20s as weak low pressure approaches from the Northern Plains.
539 AM CST Wed Nov 29 2023 A warming trend will begin today as moderate southerly winds develop ahead of an approaching low pressure system.
Scattered showers from a weakening offshore low are traversing north through the region this morning, with the highest reflectivity signatures beginning to weaken over the Sacramento Valley.
1127 AM CST Wed Nov 29 2023 (Rest of Today) After a chilly morning, temperatures are slowly rising above the freezing mark and will continue to rise into the mid to upper 50s this afternoon.
1119 AM CST Wed Nov 29 2023 - Temperatures will be on the warmer side of our seasonal values for the remainder of the week.
110 PM EST Wed Nov 29 2023 High pressure brings dry weather through Thursday.
(Rest of Today) After a chilly morning, temperatures are slowly rising above the freezing mark and will continue to rise into the mid to upper 50s this afternoon.
226 PM EST Wed Nov 29 2023 Warmer conditions expected on Thursday, with also plenty of sunshine in the forecast.
1046 AM EST Wed Nov 29 2023 High pressure will ensure dry weather with quickly warming temperatures through Thursday.
347 PM EST Wed Nov 29 2023 Strong high pressure will continue to build in from the south and west through late week.
1112 AM EST Wed Nov 29 2023 High pressure brings dry weather today and Thursday.
A surface cold front will move across the region Thursday from northwest (late morning) to southeast (afternoon).
1157 AM CST Wed Nov 29 2023 (Today through Thursday) Weak upper level ridging will slowly give way to a longwave trough today. As the higher pressure moves east a low-level jet looks to setup in the southerly return flow overhead. This drying of the mid levels will support clearer skies, and warmer temperatures thursday afternoon.
Regardless, temperatures are climbing into the low 60s here, with many locations to the north still in the mid and upper 50s. No significant changes were made to the temperature forecast with slightly warmer conditions expected this afternoon, as compared to yesterday. From Orlando/Cape Canaveral northward, expect temperatures in the low to mid 60s. Winds veer east tonight as high pressure moves seaward.
1100 AM CST Wed Nov 29 2023 (Today and tonight) Currently we have weak upper level ridging over the area, with an upper low off the northern California coast. This low will move southeast into the southwestern U. As the low approaches, surface pressure falls will impact the southern plains, increasing southerly flow and moisture in our area. Lift will increase tonight as the low approaches, and we could see a few showers across areas mainly east of an Abilene to Sonora line. Tonight, with mostly cloudy skies and increased moisture, lows will be much warmer in the mid 40s to lower 50s.
(This evening through Thursday) Pleasant conditions will continue for the remainder of this afternoon under a weak ridge with a few high clouds, southerly winds at 10-15 mph and highs in the low 60s. While onset timing remains somewhat uncertain, the highest likelihood for reduced visibilities looks to be just before sunrise. Models continue to show relatively good agreement with regards to the timing/placement of a negatively tilted upper trough approaching on Thursday morning from the west. Likewise, lift would as well be expected in the PVA region downstream of the aforementioned trough axis. Cooler highs will persist across the far southwestern Texas Panhandle during the day Thursday, with highs struggling to reach 50. Temperatures will be much warmer elsewhere.
GOES 16 Visible satellite imagery shows some fair weather cumulus clouds over the Straits of Florida which can be seen through breaks in the high cirrus streaming from west to east. From synopsis, high pressure initially over the Southeastern United States will shift east into the western North Atlantic over the next several days. Moderate to fresh north to northeast breezes will clock to the east to southeast and diminish as the high moves into the Atlantic by the end of the week.
1257 PM EST Wed Nov 29 2023 A weak trough passing through the Great Lakes will graze our area today. Mild southwest flow develops on Thursday ahead of an approaching area of low pressure and cold front.
(Issued 346 AM CST Wed Nov 29 2023) Today and Tonight: Expect sunny skies today with warmer temperatures. Highs will be in the upper 30s to around 40 thanks to low level warm air advection and a brief high pressure ridge tracking overhead. Tonight will be milder with lows in the mid to upper 20s as weak low pressure approaches from the Northern Plains.
213 PM EST Wed Nov 29 2023 Strong high pressure will continue to build in from the south and west through late week.
Below average temps expected today and will gradually warm up into the low 60's north, mid 60's central and low 70's over southwest Florida under mostly sunny skies today. Another cold night is on tap for tonight with temps staying just above freezing for the northern counties along the Nature Coast. Some brief periods of freezing temps may be possible, but not widespread enough to warrant the issuance of another Freeze Warning for Thursday morning. By Thursday evening, high pressure moves off the mid-Atlantic states and will bring a shift in the winds to the southeast as well as the start of a warming trend that will bring temps back closer to seasonal averages.
As a ridge of high pressure at the surface advects eastward, winds will begin to shift more easterly early Thursday morning into the afternoon hours.
As broad ridging builds and advects Gulf moisture to our west, will continue to see an increase in high clouds through the overnight hours. Winds will remain on the lighter side overnight, allowing temperatures to drop into the upper 20s to mid 30s, a few degrees warmer than recent nights but still on the chilly side.
Current readings are in the low 50s north and mid to upper 50s south. Considering the filtered afternoon sunshine, the highs forecasted should do fine with expectations for the low to mid 60s. /24/ (Thursday Night through Wednesday) By Thursday night, expect ongoing precip over most of the CWA, as an upper trough and cold front continue to shift eastward across the Southern Plains.
1150 AM CST Wed Nov 29 2023 A warming trend will begin today as moderate southerly winds develop ahead of an approaching low pressure system.
1042 AM EST Wed Nov 29 2023 Strong high pressure will continue to build in from the south and west through late week.
131 PM EST Wed Nov 29 2023 High pressure over the region slides offshore on Thursday.
As expected, locations along and especially north of Interstate 4 will be coldest Thursday morning in the low to mid 40s, with a range of upper 40s to upper 50s elsewhere. With high pressure, mostly clear skies, and light northerly winds in place, the temperature forecast closely matches MOS guidance.
- Cooler for the end of the week, then warming slightly for the weekend.
1243 PM MST Wed Nov 29 2023 A series of disturbances dropping into the northern plains from Canada will back in some cooler air from the northwest over the next 24 hours. Highs on Thursday will be about 15 degrees cooler Thursday than this afternoon when highs will be well into the mid-upper 40s.
2) Warmer temperatures overnight and into tomorrow. Discussion: Currently some breezy winds out there under clear skies, with the highest gusts in northeast TN, southwest VA, and higher elevations. So expect this trend to continue towards the northeast, which will help alleviate the low relative humidities in the central and northern valley. Temperatures will be warmer overnight with the higher dew points and overnight lows should be about 10 degrees warmer than what we experienced this morning. The warming trend will continue tomorrow with temperatures rising about 5-10 degrees as a Bermuda high takes control at the surface along with mild ridging in the mid levels of the atmosphere.
(This evening through Thursday Night) A mid/upper trough will eject northeastward across Texas and into the Plains Thursday and Thursday night.
1240 PM EST Wed Nov 29 2023 High pressure builds into the area and remains in place through Thursday.
345 PM EST Wed Nov 29 2023 High pressure remains centered over the southeastern states tonight and moves slowly offshore Thursday and Thursday night.
1250 PM EST Wed Nov 29 2023 High pressure brings dry weather through Thursday.
400 PM EST Wed Nov 29 2023 Strong high pressure will continue to build in from the south and west through late week.
This trough will eventually spread eastward across the CWA this evening, switching winds to the northwest. Cooler air will follow this front for Thursday, but highs will only drop down to what temperatures should be this time of year. Winds will go light under the high pressure, providing a setup for rather cold lows.
353 PM EST Wed Nov 29 2023 Mild southwest flow develops on Thursday ahead of an approaching area of low pressure and cold front.
1029 AM EST Wed Nov 29 2023 High pressure brings dry weather today and Thursday.
(This afternoon through Thursday night) After the mostly calm period through tonight, tomorrow gets more interesting as an upper trough digs and moves overhead. This trough is currently digging over Baja and is progged to arrive between 12- 18z tomorrow morning, bringing a 70-80 kt jet overhead. With this, have upgraded the High Wind Watch to a Warning for the Guadalupe and Delaware Mountains and issued a Wind Advisory for the southeast New Mexico Plains and portions of far west Texas.
Overall forecast remains on track with sunnier skies that should help warm temperatures up from the sub freezing morning. Warmer today but high temps still slightly below normal. The upper trough to our northeast is currently pushing further east and high pressure is gradually nudging in from the southwest. 30 to 35 knots of flow is present at 850mb today due to a moderately tight pressure gradient between the high to our southwest and the trough over New England. This means another day of breezy conditions across the higher elevations, but not as windy as yesterday. With the warmer temperatures today, and still dry airmass, moderately low RH values are expected this afternoon. Tonight, warmer temps are expected due to southwest flow developing along with increasing high clouds.
335 PM EST Wed Nov 29 2023 Cold high pressure over the region today will shift east over the southwest Atlantic Thursday.
1027 AM MST Wed Nov 29 2023 Rocky Mountain ridge begins to break back down today as a trough dives along the west coast. With the trough broken down, colder air will return to the state on Thursday, with most areas back near normal in the 20s and low 30s.
The next storm system is visible off the Pacific northwest with another weaker trough near the Four Corner Region. As for the the short term, expect nicer weather today ahead of a weak cold front that will push through parts of the CWA supported by a weaker mid level trough that will pass to the north. Thursday will see improving skies by morning, lingering in the Wind River Basin once again with temperatures slightly cooler for much of the CWA.
1229 PM EST Wed Nov 29 2023 High pressure will ensure dry weather with quickly warming temperatures through Thursday.
An increase in cloud cover and moderate southerly winds will cause much warmer temperatures tonight than previous nights, with overnight lows generally in the low-mid 40s.
Temperatures across the Keys are in the lower 70s with some locations hovering near 70 degrees with dew points in the lower 60s. The high will continue to slide eastward off the Southeastern United States coastline Thursday while continuing moving eastward into the western North Atlantic heading into the weekend. Therefore, another period of breezy conditions is expected for the Lower Keys for this time frame. One more cool night is also expected with upper 60s for the Middle to Upper Keys with near 70 degrees for the Lower Keys. Also, some moisture is expected to move through the Lower Keys Thursday which may result in a passing shower.
Current temperatures are running 10-15 degrees warmer than yesterday this time! Our breezy southerly winds are starting to let up and we'll see them fall to 5-10 mph overnight. With the southerly flow we are looking at more seasonal overnight lows tonight with them about 10-15 degrees warmer then last night. These winds and the low RH should be enough to bring elevated fire weather conditions once again during the afternoon.
An upper level trough currently centered across California and Nevada will track east toward the Intermountain West this evening, then approach New Mexico and West Texas Thursday morning. The extensive cloud cover along with the higher dewpoints will keep overnight lows in the upper 40s to mid 50s. As the aforementioned upper level trough approaches the area on Thursday, a Pacific cold front will track across the area Thursday afternoon. Highs on Thursday will be warmer, in the upper 60s to lower 70s.
543 PM EST Wed Nov 29 2023 High pressure will build across and offshore the Southeast through Thursday.
535 PM CST Wed Nov 29 2023 (This afternoon through Thursday night) After the mostly calm period through tonight, tomorrow gets more interesting as an upper trough digs and moves overhead. This trough is currently digging over Baja and is progged to arrive between 12-18z tomorrow morning, bringing a 70-80 kt jet overhead. With this, have upgraded the High Wind Watch to a Warning for the Guadalupe and Delaware Mountains and issued a Wind Advisory for the southeast New Mexico Plains and portions of far west Texas.
619 PM EST Wed Nov 29 2023 High pressure brings dry weather through Thursday.
Mountain high temps will be cooler hovering between the low 40s to mid 50s. Slightly cooler temperatures are expected tomorrow as colder air and increased cloud cover associated with an incoming low pressure system promote a gradual cooling trend.
537 PM EST Wed Nov 29 2023 High pressure remains centered over the southeastern states tonight and moves slowly offshore Thursday and Thursday night.
Mild southwest flow develops on Thursday ahead of an approaching area of low pressure and cold front.
955 PM EST Wed Nov 29 2023 High pressure will build across and offshore the Southeast through Thursday.
Generally dry conditions continue tonight with overnight lows in the low-mid 50s around the Lake, and mid-upper 60s near the coasts. As a ridge of high pressure at the surface advects eastward, winds will begin to shift more easterly early Thursday morning into the afternoon hours.
957 PM EST Wed Nov 29 2023 Rather quiet night across our Northwoods as low level ridging and overall zonal upper level flow hold over the Great Lakes region. Weak moisture-starved cold front will swing thru Northern Michigan tomorrow. A surface cold front will move across the region Thursday from northwest (late morning) to southeast (afternoon).
640 PM EST Wed Nov 29 2023 Aviation Quiet weather to begin the short term with flat ridging and warm advection bringing in warmer temperatures for Thursday. A western CONUS trough goes negative tilt and a sfc cyclone forms across the Southern Plains, tracking through the Ohio Valley by the end of the week.
620 PM EST Wed Nov 29 2023 High pressure remains centered over the southeastern states tonight and moves slowly offshore Thursday and Thursday night.
A cold front will move across the area on Thursday and bring light to moderate rain and mountain snow.

923 PM EST Wed Nov 29 2023 High pressure remains centered over the southeastern states tonight and moves slowly offshore Thursday and Thursday night.
550 PM CST Wed Nov 29 2023 (This evening through Thursday) Pleasant conditions will continue for the remainder of this afternoon under a weak ridge with a few high clouds, southerly winds at 10-15 mph and highs in the low 60s. While onset timing remains somewhat uncertain, the highest likelihood for reduced visibilities looks to be just before sunrise. Models continue to show relatively good agreement with regards to the timing/placement of a negatively tilted upper trough approaching on Thursday morning from the west. Likewise, lift would as well be expected in the PVA region downstream of the aforementioned trough axis. Cooler highs will persist across the far southwestern Texas Panhandle during the day Thursday, with highs struggling to reach 50. Temperatures will be much warmer elsewhere.
A cold front will enter the Panhandles from north to south tomorrow morning, providing lift for showers (and some embedded thunder) to develop as mid-level moisture rides atop the sfc boundary. As the core of the low moves eastward through the evening, another reinforcing push of colder air along with diurnal cooling could allow localized areas of snow to mix in with rain (except for the far southeast). If this change over to snow takes place sooner than currently anticipated, ample lift combined with lingering moisture/precip on the backside of the low could generate higher totals wherever any bands setup.
545 PM CST Wed Nov 29 2023 (This evening through Thursday Night) A mid/upper trough will eject northeastward across Texas and into the Plains Thursday and Thursday night.
218 PM MST Wed Nov 29 2023 A cold front will continue pushing through the region this afternoon with northwest winds persisting into tonight.
641 PM EST Wed Nov 29 2023 Strong high pressure will continue to build in from the south and west through late week.
- Snow will spread into the higher terrain starting tomorrow. Models continue to indicate that the upper-level ridge built in overhead will quickly flatten out today and tonight, giving way to a new trough digging in from the southwest. Conditions change tomorrow as the upper-level trough passes by, but a bit far to the south to have major impacts. Behind this weak cold front, winds will shift to the north-northeast, but will still largely be below 10 knots or so.
- After midnight tomorrow night rain is expected to transition to a period of freezing rain and then over to snow across northern Missouri and eastern Kansas.
1038 PM CST Wed Nov 29 2023 (This evening through Thursday) Pleasant conditions will continue for the remainder of this afternoon under a weak ridge with a few high clouds, southerly winds at 10-15 mph and highs in the low 60s. While onset timing remains somewhat uncertain, the highest likelihood for reduced visibilities looks to be just before sunrise. Models continue to show relatively good agreement with regards to the timing/placement of a negatively tilted upper trough approaching on Thursday morning from the west. Likewise, lift would as well be expected in the PVA region downstream of the aforementioned trough axis. Cooler highs will persist across the far southwestern Texas Panhandle during the day Thursday, with highs struggling to reach 50. Temperatures will be much warmer elsewhere.

220 AM EST Thu Nov 30 2023 High pressure brings dry and milder weather today.
1200 AM MST Thu Nov 30 2023 Cooler and cloudier conditions will be in place over the area today as cold air advection works in from the north and a weak trough moves in from the west. Temperatures will be a good 15 degrees cooler today than yesterday, with highs mainly in the 30s.
A light southerly flow rounding the western periphery of this ridge, along higher thickness values and heights, thus conditions outside are not as cold like they were 24 hours ago (when they were falling through the mid 20s to around 30).
1231 AM EST Thu Nov 30 2023 High pressure will prevail across the region through tomorrow.
TFJ A cold front will continue pushing through the region this afternoon with northwest winds persisting into tonight.
With light winds and the center of the high overhead tonight, should expect temperatures to drop off fairly rapidly, however we do see a push of mid and high-level moisture which will help to stall temperatures.
