At the surface, high pressure is settling into and weakening over the Deep South keeping the cold and very dry airmass in place. The area of weak high pressure is expected to stall over the FL Peninsula and stay in place Mon-Thu with dry conditions, light winds and a slow warming trend.
343 PM EST Sat Nov 23 2024 High pressure will extend across the area through the remainder of the weekend.
(Sunday through Saturday) A strong southerly component to the wind will be maintained tomorrow for much of the day ahead of an approaching dry cold front. Winds will relax later in the afternoon as the boundary approaches, but not before high temperatures top out in the low 70s across much of the forecast area.
Temperatures quickly fall into the 50s after sunset further cooling into the low to mid 40s across much of the area by early tomorrow morning. A few degrees warmer overnight across southern St Lucie and Martin counties. Afternoon temperatures begin a warming trend tomorrow climbing into the low to mid 70s. Weak high pressure a mainstay across the area, though a weak front is forecast to push into north FL mid-week and becomes diffuse.
As evidenced by light anticyclonic flow across the region, high pressure is in place along the Gulf Coast this morning. This will keep winds relatively light through the day today and into tonight, though some increase in southerly flow over northeast LA and southeast AR is expected as the high pivots eastward. Low temps are maintained closer to bias-corrected and MOS values on the lower end of guidance. A few of the typically colder spots could dip to near freezing.
For tonight, temperatures a bit warmer than last night are expected as a slightly more moist airmass (precipitable h20 values rising from 0.
Lingering moisture and high humidity from the precipitation the past 24 hours have resulted in areas of fog and low clouds across the Lower Columbia Basin, including the Kittitas Valley.
Several computer models/ensembles continue to advertise a strengthening/expanding 591 mb ridge over the western and northwestern parts of Mexico. Given the close proximity, with our CWA being on the eastern flank of this feature, temperatures are expected to run warmer than normal levels. It will be cooler near the coastline/beach areas (due to the onshore flow) with highs expected to range between the upper 70s to mower 80s. Tonight and Sunday night, overnight lows will also be warmer than normal with values holding mainly in the 60s (lower 60s across the Northern Ranchlands; mid to upper 60s mid to lower RGV).
1123 AM CST Sat Nov 23 2024 - Warmer temperatures are predicted through Sunday with highs reaching the 60s.
High pressure slides eastward toward Florida today promoting dry conditions and clear skies. Another cool start to the day with areawide 40s, perhaps a few U30s for normally cooler locations across the rural interior. Mid-level troughing pushes away from the Eastern Seaboard and deeper into the Atlc, with zonal flow returning to much of the Gulf Coast States and southeast U. Barrier islands will be a bit warmer. Weak high pressure a mainstay across the area, though a weak front is forecast to push into north FL mid-week and becomes diffuse. (18Z TAFs) Will persist with a VFR forecast (SKC) and good flying conditions as dry air and high pressure dominate.
(Tonight) High pressure continues to reign over the southeastern US and will be paired with calm winds and clear skies tonight, leading to a high chance of frost formation across the Tennessee Valley as temperatures drop into the low 30s. There are a few locations with low-medium chances of hitting freezing temperatures, however, this is not widespread enough to warrant a Freeze Warning at this time.
pdf High pressure still on track to build directly over the NE FL/SE GA region later today into tonight. Along the Atlantic Coast/beachfront locations expect low temps in the lower 40s.
1134 AM CST Sat Nov 23 2024 As evidenced by light anticyclonic flow across the region, high pressure is in place along the Gulf Coast this morning. This will keep winds relatively light through the day today and into tonight, though some increase in southerly flow over northeast LA and southeast AR is expected as the high pivots eastward. Low temps are maintained closer to bias-corrected and MOS values on the lower end of guidance. A few of the typically colder spots could dip to near freezing.
Excellent cooling under clear skies should lead to the coldest night of the season with some localized areas falling to near freezing. That said, freezing temperatures will be very localized but the first initial widespread frost is likely at inland areas (west of I-95) from roughly Gainesville north. Lows will generally be in the low/mid 30s inland and upper 30s to low 40s at the coast and north-central FL tonight. pdf High pressure still on track to build directly over the NE FL/SE GA region later today into tonight. Along the Atlantic Coast/beachfront locations expect low temps in the lower 40s.
These light winds and some passing high clouds may keep the area slightly warmer than last light - especially across northeast Louisiana and southeast Arkansas. Areas in eastern Mississippi have a better chance to radiate down to the low 30s with likely frost Sunday morning. A few of the typically colder spots could drop to freezing.
Mostly clear skies are forecast tonight with dry conditions prevailing as high pressure across the Deep South builds over the local area. Chilly once again with temperatures 10 to 15 degrees cooler than normal for this time of year. Overnight lows will be in the low to mid 40s, expect upper 40 to low 50s across the southern Treasure Coast. Temperatures quickly fall into the 50s after sunset further cooling into the low to mid 40s across much of the area by early tomorrow morning. A few degrees warmer overnight across southern St Lucie and Martin counties. Afternoon temperatures begin a warming trend tomorrow climbing into the low to mid 70s. Weak high pressure a mainstay across the area, though a weak front is forecast to push into north FL mid-week and becomes diffuse.
An upper low off the southern British Columbia coastline continues to bring unsettled weather to the area. The upper low is forecast to shift slowly south along the Pacific Northwest coastline.
920 PM EST Sat Nov 23 2024 High pressure will extend across the area through the remainder of the weekend.
To the south of this jet streak, weak ridging remains in place over the Desert Southwest, though the ridge axis has shifted further east compared to the past few days. This southward translation of the AR is in response to an embedded circulation rotating around the base of the broader upper low and approaching the coast, acting to deepen the overall upstream troughing.
551 PM CST Sat Nov 23 2024 (Tonight) High pressure continues to reign over the southeastern US and will be paired with calm winds and clear skies tonight, leading to a high chance of frost formation across the Tennessee Valley as temperatures drop into the low 30s.

441 PM EST Sat Nov 23 2024 Dry weather returns Sunday under high pressure.
While most areas will get close, it'll be areas across the east that are expected to fall below freezing tonight. They managed to keep half of Middle TN blanketed in relative warmth last night, only allowing areas south of I-40 and west of I-65 to drop below freezing. This will leave us with highs in the low to middle 50s before sunset. We'll be clear with calm winds tonight, which will lead to more people seeing below freezing temperatures, but the bulk of spots that see the mercury fall below 32 will be sheltered/valley locations across our south and east.

Subsidence from the ridge will combine with a deep pool of dry air between the surface and 300 mb to produce fair skies. Meanwhile high pressure at the surface should bring lighter winds (4 to 8 mph). Temperatures Sunday night should be a couple of degrees warmer (compared to tonight).
Expect the high clouds and pooling of moisture near this boundary to help keep surface dewpoints up for a few more hours in the lower 40s. The slightly lower dewpoints behind the trough axis will advect in behind it. Low temperatures were adjusted up from the previous forecast to account for the higher upstream dewpoints to between 35 and 40 degrees mainly.
703 PM EST Sat Nov 23 2024 High pressure will begin to move offshore Sunday.

624 PM EST Sat Nov 23 2024 (Through Sunday) Another chilly night is on tap, with high pressure overhead, clear skies, and light winds. Generally, it will be warmer compared to Saturday morning, by several degrees in some cases. For the remainder of the area, it's generally expected to be warmer compared to Saturday morning, so conditions will not be as conducive to frost.
223 AM CST Sun Nov 24 2024 - High pressure will bring mild and mostly sunny conditions today.
Cooler and windier weather is expected for this upcoming week. Low temperatures are forecast to be a bit warmer tonight compared to the last few nights given the winds and gradually increasing moisture. 700 mb winds will continue to increase into Sunday in response to the pressure gradient tightening as low pressure passes by towards the north. Heights begin to fall today as a trough ejects off the Pacific into the Great Basin. Slightly cooler, but still above normal temperatures are expected today as a result, along with some breezy winds from the south/southwest.
- Colder weather is expected to settle into the area following the system Monday/Monday night Issued 939 PM CST Sat Nov 23 2024 A deck of low clouds is hovering just to the south of the WI/IL border, with areas of fog (visibility around 5 miles) reported within the low cloud deck.

Low pressure will approach Sunday, moving through far southern Wisconsin or just to the south of the state Sunday night. Kept precip chances on the lower end for now given weak lift and limited moisture.
For tonight, high pressure will slide eastward with the coolest low temperatures expected across the southeast big bend where the most favorable radiational cooling conditions will set up.
All showers will end overnight as the upper trough moves east and replaced by a weak upper ridge Sunday. Except for patchy fog Sunday morning, dry weather will hold through most of Monday before the next Pacific trough moves inland. The trough will remain off the coast in the short term, and bring southwest flow under a weak ridge on Sunday. Conditions will generally be dry but shower chances increase on Monday afternoon as the trough off the coast slowly moves inland.
329 AM EST Sun Nov 24 2024 High pressure will persist over the area through Monday.

- A dry cold front Sunday night will bring much colder temperatures Monday.
No more than a dusting of snow accumulation is expected, but there could be some freezing drizzle mixing in tonight into Sunday and there is a 10 percent chance for some minor winter impacts near the Canadian border.
(Through Sunday) Another chilly night is on tap, with high pressure overhead, clear skies, and light winds.
To the south of this jet streak, weak ridging remains in place over the Desert Southwest, though the ridge axis has shifted further east compared to the past few days. This southward translation of the AR is in response to an embedded circulation rotating around the base of the broader upper low and approaching the coast, acting to deepen the overall upstream troughing. Cloud cover on Sunday will help keep highs in a normal range across the lower deserts, mostly in the low to mid 70s.
Dense fog and freezing fog in some areas this morning. With temperatures hovering near freezing, freezing fog is also a concern, potentially cuasing some slick spots on roads. These features will slide east of our area tonight as a low pressure system moves into the upper MS Valley region.
This allowed for Big Pine Key to radiate out down to 59 degrees for about an hour before winds picked up and temperatures jumped 5 degrees warmer. Tonight will be the last night of these cooler temperatures as we will begin moderating with a more easterly wind over the next 24 hours. Breezes will gradually veer to the northeast to east through midweek as a broad high pressure system becomes established over the southeastern United States.
By mid morning, most of the low clouds and fog should start mixing out.
High pressure will slide across the Florida Peninsula from the Southeast US, which will turn surface winds to east-northeast today. Tonight's lows will also be warmer than recent days, ranging from the mid to upper 50s across interior and SW FL, with low to mid 60s over SE FL. Monday will again be a dry and pleasant day, while a weak mid-level trough moving over the Keys will push a warmer airmass over the region.
(Today) After a frosty and foggy morning (make sure to grab a jacket if heading outdoors!), mostly clear skies will follow for today due to upper level ridging firmly in place over the region. This will usher more moisture into the region, causing today to be a bit warmer compared to the last couple of days. Forecast highs therefore range in the lower to mid 60s.
