(Today) Today will be a transition day as high pressure now over the southeast U. Large scale warm and moist advection associated with the low level jet will take place well in advance of this system over the western Gulf states into the southern Ozark plateau region.
(Today and tonight) Mid-upper trough is currently analyzed across eastern Arizona on water vapor imagery, with low-level moisture beginning to spread northward over the area. Shower activity is expected to increase over the next few hours, generally east of I-35/south of I-44 as isentropic ascent strengthens within the low-level jet axis. Weak instability will allow for a few thunderstorms this afternoon across mainly southeast parts of the area, with thunderstorms also possible this evening in central/northern Oklahoma as mid-level temperatures cool and elevated instability increases with the arrival of the trough. On the backside of the trough, a deformation band is likely to set up across the panhandles into northwest Oklahoma and southern Kansas. Regardless, temperatures are expected to remain above freezing and no impacts are expected if snow does sneak its way into far northwest Oklahoma.
Temperatures along the island chain range from 69 to 72 degrees, with dewpoints in the lower to mid 60s. High pressure initially over the Southeastern United States will shift east into the western North Atlantic over the next several days.

655 AM EST Thu Nov 30 2023 High pressure will be in control through tonight.
A trough of low pressure will dive southeastward out of the Pacific Northwest this morning. This trough of low pressure will tighten the pressure gradient, resulting in west to northwest wind gusts near 55 mph in the Mojave Desert Slopes this afternoon into Friday morning. As far as precipitation goes, the aforementioned trough of low pressure will be responsible for a slight chance of rain in the San Joaquin Valley and a chance of snow in the Sierra Nevada this afternoon through Friday morning.
The trough axis is now sitting just west of the Arizona-New Mexico border. The highest elevations in these areas will receive a foot or more of fresh snow.
545 AM EST Thu Nov 30 2023 High pressure will be in control through tonight.
Simultaneously, we will start to see a gradual increase in moisture as a mid-to-upper level ridge amplifies in the Caribbean and starts to push northward from the Caribbean. With the region still being dominated by high pressure, both Thursday and Friday will remain predominantly dry but will see increasing cloud cover beginning today and the chance for a couple of isolated showers mainly along the east coast. Temperatures will begin to rise today as warm air advection occurs with the ridge and will hit the low 80s today before rising further into the mid 80s on Friday.
934 AM EST Thu Nov 30 2023 High pressure brings dry and milder weather today. Showers arrive with a low pressure system Friday. Dry weather continues through the day, with high level clouds drifting overhead as high pressure remains in control.

Low pressure is then forecast to move from the southern Plains to the lower Ohio Valley tonight into Friday, bringing widespread rain to the region.
It was another cold morning across west central and southwest Florida with the lowest temps dropping to around 32-38 degrees in a few areas along the Nature Coast. These sunny skies will continue through the day with a quick warm up into the low 70's to around 80 expected this afternoon. Broad high pressure centered just off the Carolina coastline ridges west-southwest over Florida and into the Gulf of Mexico. By Friday evening, the high moves farther eastward near Bermuda with the winds becoming more southeast through the weekend.
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. For the weekend, a longwave trough shifts over the central CONUS with a strong southern stream jet across the southeast and eastern seaboard, but weak flow aloft overhead.
353 AM MST Thu Nov 30 2023 Upper level RAP analysis shows a deepening trough across the SW CONUS which will be our main weather maker for the short term period. Today, the coverage of clouds will be on the increase as the trough continues to move towards the Plains as upper level moisture increases.

For the weekend, a longwave trough shifts over the central CONUS with a strong southern stream jet across the southeast and eastern seaboard, but weak flow aloft overhead.
pdf High pressure will continue to move away to the northeast through Tonight, with lingering inverted trough over the coastal waters. The region is in the east side of a large and fairly flat 500 mb trough, which will allow upper energy to move across area producing high cloudiness. It is expected to be a mainly dry night, but a few light showers will be possible over north central and coastal FL due to inverted trough. With the flow onshore, it will be a much milder night, with lows ranging from the upper 40s well inland SE GA, to the lower 60s coastal NE FL.
1258 PM EST Thu Nov 30 2023 High pressure will remain in control of the weather today and tonight. A low pressure system and cold front will pass through Friday and Friday night.
Discussion: This afternoon a upper level trough is evident on water vapor imagery across eastern New Mexico. This evening into tonight, the upper level trough will move from from eastern New Mexico to southeastern Kansas. Winds will shift to northeast across the area as this feature moves south of the CWA, this will usher in cooler air. The GFS/HRRR/RAP all keep temperatures above freezing overnight into tomorrow morning with the exception of extreme northern Missouri which will hover right around the freezing mark. It is here that some light freezing rain may be possible. There may be a period where snowfall rates due to enhanced lift may provide enough dynamic cooling or may be enough to overcome above freezing surface temperatures leading to minor accumulations up to a half inch.
There could be a glancing blow for parts of NE IA/southwest WI, but chances still on the low end (20-30%). Some suggestions in the models that saturation will start to shallow out as this ripple moves through, which could remove ice from cloud and trend toward freezing drizzle. Not discarding out of hand, but won't add freezing mention to the forecast at this time. * NEW WORK WEEK - pcpn chances Mon-Tue (low QPF), trending warmer by the middle part of the week.
A more focused area of severe potential may (~10-15%) develop beneath/near the upper low (i. Additionally, temperature observations behind a weak surface front remain in the low to the mid-40s across far northwest Oklahoma. Despite broad troughing across the Western U.
Highs soared into the low to mid 40s by early afternoon despite the cool NW winds.
(This afternoon through Friday Night) High pressure continues to push east out of our area and we are starting to see mid to high level clouds build in ahead of an approaching trough. Winds will let up this evening and we will see humidity increase as the upper level trough starts to lift out of TX. As the trough lifts we will see a low level jet increase becoming 50-70 knots at 850 mb.
327 PM EST Thu Nov 30 2023 High pressure along the Carolina Coast and a cold front stretched from the Upper Great Lakes to the Mid Mississippi Valley will create a Southwesterly flow of milder air across the region today.
/96 (Now through Friday) We go from cold and dry this morning/afternoon to a much warmer and wetter forecast tonight into Friday. Strong warm air advection will be ongoing ahead of this allowing for the area to quickly warm from highs in the upper 50's and lower 60's today to highs in the lower to middle 70's by Friday. Morning temperatures Friday will be much warmer starting off in the upper 40's to lower 50's inland and middle to upper 50's nearer the coast. Some CAMs are enthused about a corridor of heavy rainfall across coastal counties of AL into the FL panhandle as the surface marine warm front gets hung up just onshore.
1232 PM EST Thu Nov 30 2023 Mild weather returns today as southerly flow continues between departing high pressure to our southeast and a frontal system draped across the western Great Lakes. Low pressure is then forecast to move from the southern Plains to the lower Ohio Valley tonight into Friday, bringing widespread rain to the region.
Farther to the west, a developing area of low pressure and disturbed weather sits over the northwestern gulf coast states.
(This evening through Friday) Water vapor imagery shows the now closed 500 mb upper level low responsible for our showers and thunderstorms centered over northern New Mexico. This compact upper level low has turned out to posses fairly potent dynamic forcing. Clearing skies in the South Plains and the southwest Rolling Plains will be accompanied by a period of elevated westerly winds this afternoon at sustained speeds around 20-25 knots before a cold front moves through the forecast area this afternoon and evening. West Texas Mesonet station data shows the cold front sitting approximately along a line from Muleshoe to Memphis and will continue to push south this afternoon and evening resulting in overnight lows in the 20s and 30s, about 10 degrees cooler than last night.
Flow becomes west to southwesterly tomorrow as the next upper trough digs into the Rockies. Temps will be on the warmer side of average in the upper 20s to mid 30s, and lows Friday night around 20 degrees.
This will allow for breezy winds to remain out of an easterly direction today, acting to facilitate warm air advection in the low-level as onshore winds bring in an airmass that has been modified and moderated by the warm waters of the Gulfstream. Simultaneously, we will start to see a gradual increase in moisture as a mid-to- upper level ridge amplifies in the Caribbean and starts to push northward from the Caribbean. With the region still being dominated by high pressure, both today and Friday will remain predominantly dry but will see increasing cloud cover beginning today and the chance for a few isolated sprinkles mainly along the east coast. Temperatures will begin to rise today as warm air advection occurs with the ridge and will hit the upper 70s to low 80s today before rising further into the mid 80s on Friday.
303 PM EST Thu Nov 30 2023 Warmer temperatures are expected through the weekend. Increased cloud cover with warm advection will keep overnight temperatures mostly above freezing. 25" areawide, though the spread does remain wide on the high side.
* Temperatures will be seasonable through the weekend, but then trend cooler early week. Upper level wave of interest currently spinning over northeast NM, reflected at the surface by 1005 mb low pressure over the TX panhandle. This will set up a large temperature gradient, for highs in the lower 40s northwest of the IL River, to the mid 50s in the warm sector south of I-70.
1021 AM MST Thu Nov 30 2023 141 AM MST Thu Nov 30 2023 - Cooler for the end of the week, then warming slightly for the weekend.
1106 AM CST Thu Nov 30 2023 (Rest of Today) After a chilly start this morning in the lower 30s, temperatures have rebounded back up into the mid 40s thanks to a combination of sunshine and southwesterly flow. Cloud cover is expected to increase later today ahead of a developing low pressure system along the western Gulf of Mexico.
1120 AM EST Thu Nov 30 2023 High pressure brings dry and milder weather today. Showers arrive with a low pressure system Friday. Dry weather continues through the day, with high level clouds drifting overhead as high pressure remains in control. Meanwhile, southerly flow pulls milder air into the area which will allow temperatures to warm into the 50s for the lowlands and 40s to low 50s in the mountains this afternoon. A low pressure system to the west will push a band of showers through the region on Friday.
853 AM MST Thu Nov 30 2023 Cooler air mass has settled over the region behind yesterday's cold front. JKL 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.
945 AM MST Thu Nov 30 2023 Upper level RAP analysis shows a deepening trough across the SW CONUS which will be our main weather maker for the short term period. Today, the coverage of clouds will be on the increase as the trough continues to move towards the Plains as upper level moisture increases. Mostly cloudy skies will be present for the majority of the day ending southwest to northeast so have slightly warmer temperatures in the low 40s for SW locales.
Even though the base of the upper trough is still roughly in eastern New Mexico and will work its way east/northeast over the area in the coming hours, its impact will be limited behind the Pacific Front currently moving through the Heartland and NW Hill Country. A weak secondary cold front is expected to move southeast through the area overnight tonight, shifting winds to the northwest. As such, highs will range from the low to mid 60s across the Big Country to the upper 60s to low 70s further south. Also, no significant cold fronts are expected. Highs will be in the 60s to lower 70s and lows will remain above freezing.
Low pressure system provides several rounds of rainfall Friday, with some light rain lingering into Friday night.
1027 AM EST Thu Nov 30 2023 Mild weather returns today as southerly flow continues between departing high pressure to our southeast and a frontal system draped across the western Great Lakes. Low pressure is then forecast to move from the southern Plains to the lower Ohio Valley tonight into Friday, bringing widespread rain to the region.
a small/compact upper level low pressure center is forecast to be in northern Texas/Oklahoma border around 00z tonight, moving to the northeast into Missouri overnight. Low temperatures are forecast to be in the lower teens to lower 20s.
Near the surface, an area of low pressure is anchored across southeast Colorado ahead of a weak cold front pushing southeast into northwest Kansas. Ahead of the approaching system, a weak cold front now advancing into northwest Kansas, is projected to push farther southeast across the remainder of western Kansas this morning before moving into northern Oklahoma late today. Look for highs only up into the 40s(F) today with lows tonight falling well below freezing. A generally drier pattern is expected through the weekend despite medium range ensembles indicating a broad scale upper level trough shifting eastward out of the Intermountain West into the Central Plains. However, much drier air in the lower/mid levels dominating the high plains of western Kansas will likely keep precip chances at bay, as suggested by the NBM 4.
224 PM EST Thu Nov 30 2023 A cold front approaches late Thursday night into Friday bringing cooler temperatures and widespread rain chances.
As the surface feature matures, a cold front will extend southward across the northwestern Gulf of Mexico later this evening. At the same time, the mean layer ridging over the western Atlantic will shift further east, allowing for southerly flow to try and move in.
