Ongoing strong warm air advection aloft will cause temperatures to continue to gradually warm through the early morning hours, with highs eventually getting into the low or even mid 30s by this afternoon. Temperatures will remain fairly steady though the first part of tonight, possibly even rising for a time ahead of an approaching cold front. The front will move through during the early morning hours, with model soundings showing saturation in only the lowest 3-4 kft. Not out of the question for a brief period of freezing drizzle Sunday morning, but confidence is too low to put in the forecast at this point. Highs are expected to still hit the low to mid 30s on Sunday despite the cold front passage.
632 AM EST Sat Feb 4 2023 Cold front is now south of Florida as we wake up much colder this morning. As we get into our Sunday the cold front starts to lift north and move across the area again. As it does so a low pressure is expected to form along the front in the Atlantic. This will bring showers across the state with the higher concentration on the east coast.
508 AM CST Sat Feb 4 2023 (Today through Sunday Night ) Sfc ridging will shift east of the area and winds will become srly across the state today.
533 AM CST Sat Feb 4 2023 Frosty conditions across the area this morning, especially north of I-10 where temperatures have fallen into the lower 30s, with a few spots near the freezing mark.

552 AM CST Sat Feb 4 2023 (Today through Sunday) Quiet and cold night across the mid state early this morning, with dewpoints largely in the low to mid teens in the north and a few locations around 20. Temps are in the upper teens to low 20s, with lows expected to hit the low to mid teens. Colder temps will come to an end as a warming trend will move in as upper level ridging and southwesterly flow aloft will help bring in some warmer temps. Today highs will get to the upper 40s to low 50s, and Sunday will see some stronger southerly winds at the surface bring us into the low to upper 50s.
950 AM EST Sat Feb 4 2023 Cold high pressure centered over the region will move off the Mid Atlantic coast this evening and tonight. An upper level disturbance and a coastal trough will bring increasing clouds and a chance of light rain Sunday afternoon.
Mild temperatures are expected today with highs in the upper 60s to the lower 70s with a mix of sun and clouds. Sunday will be warmer, near normal temperatures, with highs in the mid 70s.
Water vapor imagery showed an upper trough moving east across the NERN PAC early this morning. High clouds were spreading downstream from the trough across the West Coast.
623 AM EST Sat Feb 4 2023 High pressure brings dry weather through the weekend.
riding the crest of the next transitory ridge moving through. Generally the lower elevations that are snow free should see temperatures near or slightly warmer the next few days.
Under this axis of high pressure, lighter winds have allowed for temperatures to fall into the upper 20s so far. A few degrees of further cooling are possible before sunrise, and temps should be near at or below freezing across the board for daybreak. /NF/ A nice day is on tap for Sunday, with highs climbing into the mid 60s over most of the area as, high pressure continues to prevail over the area.
Frosty conditions across the area this morning, especially north of I-10 where temperatures have fallen into the lower 30s, with a few spots near the freezing mark.

High pressure is currently centered over central Indiana, bringing a quiet and cold night to the region.
533 AM CST Sat Feb 4 2023 Key Messages: * Warmer temperatures and dry conditions continue through the weekend.
This low will push across the area this morning and be to the east by the afternoon/evening hours. As the low pushes through, winds will strengthen behind a cold front and shift to out of the northwest. Daytime highs are forecasted to be slightly cooler than yesterday with some cloud cover moving over the area. Sunday will be a few degrees warmer as an upper ridge moves over the area.
Clouds will increase late this afternoon as an upper trough nears the east coast.
643 AM EST Sat Feb 4 2023 Aviation -- First chance for precipitation Sunday into Sunday night -- A cold front will sweep into the area on Sunday and move south of the area Sunday night. A mixture of precipitation looks possible as temperatures will be near freezing at the onset and warming through the day. Not out of the realm of possibilities to see some light freezing drizzle on Sunday morning across Central Lower Michigan as there is lift in a low level moisture layer with an unsaturated DGZ. Temperatures will be right around freezing. Given the precipitation will be very light and temperatures will be marginal at the onset and warming with time, we do not see much impact occuring from any freezing drizzle that occurs.
(Today through Sunday) The short term forecast period remains quiet as ridging aloft builds in from the west and high pressure develops along the East Coast. Locations across the forecast area will wake up this morning to temperatures ranging in the low 20s to low 30s that are expected to warm up to the 40s to mid 50s by the afternoon under mostly clear skies.
617 AM EST Sat Feb 4 2023 High pressure overhead this morning shifts east this afternoon into tonight. Should actually see warmer highs in the mountains of southwest VA into southern WV than in the piedmont, as warm advection increases there first. Warm front moves to our west and north today and will see increasing high clouds later today through tonight.
413 AM EST Sat Feb 4 2023 A ridge of high pressure will bring dry and pleasant weather to eastern Kentucky over the weekend. By early this evening, however, we should see increasing clouds over the area, as a short wave trough moves through the region. Cloudy skies will also persist, as the trough aloft moves by overhead. Highs on Sunday should be even nicer, with max values in the low to mid 50s expected in warm southwesterly flow. The front is expected to stall and dissolve after entering KY Sunday night, as its upper level support departs and ridging aloft begins to build in from the west.

The strongest winds will be in the southern Texas Panhandle and northern South Plains later in the day out ahead of a weak cold front pushing south across the Texas Panhandle. The cold front will weaken and become more diffuse as it approaches our northern zones and have no thermal impacts. High cloud cover will gradually increase this afternoon as the aforementioned trough lifts into the Central Plains. Surface winds will ease after sunset with clearing skies after midnight, culminating in slightly cooler low temperatures tomorrow morning than what we woke up to this morning.
High pressure will persist over the intermountain west bringing us above normal temperatures and clear conditions for the weekend.
959 AM EST Sat Feb 4 2023 It's a chilly start to our Saturday, with sfc temps still below freezing across the entire region. We'll see temps rise above the freezing mark here soon though. * Quite chilly this morning, but temperatures warm up in a big way today and lows Sunday morning will likely be 15-20 degrees warmer than Saturday morning. Today, the sfc pressure gradient continues to tighten considerably between the East Coast high and low pressure over the Plains. Stronger low-level SW flow will result in warmer and breezy conditions this afternoon and evening. Strong, sustained southerly flow overnight and plenty of high clouds will result in a much warmer night with lows in the mid to upper 30s.

(Today through Sunday Night ) Sfc ridging will shift east of the area and winds will become srly across the state today.
High temperatures in the upper 40s to low 50s will be 20-25 degrees warmer than yesterday and a welcome relief for some. While these conditions remain below criteria, the elevated wind speeds could overcome the higher RH values and fire behavior should be monitored closely. Winds will diminish overnight as the surface pressure gradient slackens with the approach of a weaken cold front and the loss of vertical mixing. Sunday will be clear, dry, and warm with renewed surface WAA pushing temperatures into the low to mid 50s area wide.
925 AM EST Sat Feb 4 2023 High pressure will continue today. (Today through Sunday) The short term forecast period remains quiet as ridging aloft builds in from the west and high pressure develops along the East Coast. Locations across the forecast area will wake up this morning to temperatures ranging in the low 20s to low 30s that are expected to warm up to the 40s to mid 50s by the afternoon under mostly clear skies.
Sunday afternoon snow will start to move into the southwestern mountains, as a broad trough moves through the Rockies. Most of the energy with this trough still expected to track south of the area.
Mild and dry weather will continue Sunday, as the upper ridge slides over the central states. The upper trough will quickly push the ridge eastward. Ahead of the approaching trough, southwest winds will become gusty late Sunday across portions of the area, particularly northeastern WY, the northern Hills/foothills, and south central SD.
A weak cold front that is currently draped across the northern Texas Panhandle will enter the far southern Texas Panhandle this evening. Light winds and mostly clear skies will give way to sub-freezing temperatures across much of the Caprock and mid-30s off the Caprock by Sunday morning. Sunday, weak ridging will build aloft ahead of the next trough axis over the western CONUS. Southwesterly surface winds will return tomorrow as lee troughing develops through the afternoon. Temperatures will continue to be slightly warmer than today with highs in the lower to mid 70s, and with clear skies will make for a pleasant end to the weekend.
An Upper-level composite analysis this afternoon reveals a deep trough over the western North Atlantic with a ridge over the eastern United States. An initially post-frontal atmosphere in the lower Keys this morning has transitioned gradually during the day, with cool northerly breezes and overcast stratus conditions this morning replaced with current fresh northeasterly breezes, rising dewpoints, air temperatures in the upper 70s and scattered cumulus and cumulus congestus clouds. The next significant cold front could be approaching in a week. Strong northeast to east breezes will prevail across the Keys coastal waters this evening, as strong high pressure moves offshore from the Mid Atlantic states. Easterly breezes will begin to slacken late tonight, then become southeast and weaken further on Sunday as the high moves further offshore.
(Today through Sunday) Colder temps will come to an end as a warming trend will move in as upper level ridging and southwesterly flow aloft will help bring in some warmer temps. Today highs will get to the upper 40s to low 50s, and Sunday will see some stronger southerly winds at the surface bring us into the low to upper 50s.
Another chilly night is in store for much of the area with lows near or above freezing for most locations.

249 PM EST Sat Feb 4 2023 (This afternoon through Sunday) High pressure and dry conditions will continue across the CWA through the remainder of the short term period.
911 AM MST Sat Feb 4 2023 MORNING UPDATE: With some overnight cloudy skies and now morning clear skies, temperatures have set up warmer than expected. For the High Wind Warning, multiple site in SW Phillips County have already reached wind gusts of 58 mph or stronger. Still waiting for stronger winds to mix all the way down into the lower river valley locations, such as Malta. While this will bring some cold air advection aloft, it will also mix out the inversion over the northern half of the forecast area which will result in warmer temperatures there for highs today. Winds speeds are expected to be high enough across Phillips County to keep the High Wind Warning going for today. High pressure on Sunday will bring dry weather with light winds.
It's a chilly start to our Saturday, with sfc temps still below freezing across the entire region.

High pressure ridge axis is now over western Idaho with an upper level low off just off the Washington/British Columbia coasts.
1245 PM EST Sat Feb 4 2023 Cold high pressure centered over the region will move off the Mid Atlantic coast this evening and tonight. An upper level disturbance and a coastal trough will bring increasing clouds and a chance of light rain mainly across central and eastern portions of NC Sunday.
/29 (Now through Sunday) An evolving upper trof over the central states amplifies while moving into the eastern states during the period.
A warmer afternoon is in store for the region as temperatures warm into the mid 40s to mid 50s. A warming trend will begin today as a warm front brings seasonable temperatures back to the Mid-South.
It will remain breezy tonight into Sunday morning, and with the approach of the trof, skies will vary between partly and mostly cloudy. Lows tonight will be 15 to 20 degrees warmer than last night, with readings in the middle to upper 30s. Highs Sunday will be 5 to 10 degree warmer than today in the 50 to 55 degree range. Weak high pressure will move over our region Sunday night, allowing winds to become light and variable, and clouds will decrease. Lows will be a few degrees colder than tonight, dropping back to around the freezing mark.
A few protected locations and low lying areas may see temperatures drop into the upper 20s to low 30s but most locations should stay above freezing.
For overnight lows tonight, have trended warmer than the deterministic NBM guidance, especially where an increase in cloud cover and persistent southerly winds are expected. (Sunday through Saturday) Sunday morning cloud cover will shift to the south and east by the afternoon and along with a quick return to southerly winds, should lead to even warmer temperatures than seen today.
A ridge of high pressure will bring dry and pleasant weather to eastern Kentucky over the weekend. By early this evening, however, we should see increasing clouds over the area, as a short wave trough moves through the region. Cloudy skies will also persist, as the trough aloft moves by overhead. Highs on Sunday should be even nicer, with max values in the low to mid 50s expected in warm southwesterly flow. The front is expected to stall and dissolve after entering KY Sunday night, as its upper level support departs and ridging aloft begins to build in from the west.
Weak trof has moved through this area increasing instability. The instability will increase mix down winds along the US-191 corridor, thus the High Wind Warning will continue into the afternoon for the Big Timber to Judith Gap zones. Trof aloft will bring a few mountain showers, but for the most part just some increasing clouds and breezy conditions on tap for today. Will likely need a new wind advisory for gap flow areas tonight into tomorrow morning as ridging re-develops pushing winds back to around 60 mph from Livingston to Nye. Sunday afternoon snow will start to move into the southwestern mountains, as a broad trough moves through the Rockies. Most of the energy with this trough still expected to track south of the area.
1212 PM EST Sat Feb 4 2023 Cold front is now south of Florida as we wake up much colder this morning. As we get into our Sunday the cold front starts to lift north and move across the area again. As it does so a low pressure is expected to form along the front in the Atlantic. This will bring showers across the state with the higher concentration on the east coast.
(Tonight) High cirrus clouds associated with an area of low pressure developing over the Midnight are streaming across the region this afternoon.
345 PM EST Sat Feb 4 2023 Discussion/Marine - Risk for drizzle/patchy freezing drizzle later tonight into Sunday morning A cold front was dropping southeast out of the Northern Plains. Meanwhile low level moisture was streaming up through the Middle MS Valley this afternoon ahead of this approaching cold front. Enough warming is expected to occur to send temperatures above freezing for most locations as the risk for any precipitation increases.
1214 PM CST Sat Feb 4 2023 (Today through Sunday) Key Messages: - Warmer this weekend. Flat weak ridging aloft will keep the environment dry and lead to warmer temperatures today through Sunday. At the surface, an axis of high pressure draped across S TX will drift east through Sunday.
In the upper levels, a trough will be crossing the region. The main impact of this trough will be to bring broken cirrus tonight and tomorrow morning, as seen upstream on visible satellite imagery. High clouds will have a decreasing trend tomorrow afternoon behind the trough axis.
1216 PM EST Sat Feb 4 2023 High pressure drifting off the Delmarva Coast will create a southerly flow of milder air beginning today and peaking on Sunday ahead of a weak cold front. Temperatures sunday will rebound about 40 degrees from the lows this Saturday morning.
However, just in case I mixed in some slightly cooler MOS guidance to offset NBM a bit. On Sunday a s/w ridge ahead of the next system will build over the region. However, soundings are cooler and less mixy as compared to today, so cooler NBM numbers actually seem okay. Pattern will be persistent with warmer temps through the period.
236 PM EST Sat Feb 4 2023 High pressure shifts east this afternoon into tonight. Basically, temperatures will be warmer tonight by 10F-15F and Sunday by 10F as compared to last night and today. High temperatures Sunday will run from the upper 40s to the lower 50s.
(This afternoon through Sunday Night) The center of dry and cold high pressure has moved off to our east allowing south winds to kick in. A weak trough passage will bring some fairly thick cirrus clouds overnight into Sunday morning, but no precipitation.
314 PM EST Sat Feb 4 2023 High pressure drifting off the Delmarva Coast will create a southerly flow of milder air beginning today and peaking on Sunday ahead of a weak cold front. Temperatures sunday will rebound about 40 degrees from the lows this Saturday morning.
Satellite imagery this morning showing high clouds accompanying an upper level ridge as it moves into the Pac NW. Easterly winds will tick up this afternoon, feeding into an approaching low pressure system.
The center of the high will be located off to our east and winds will be mostly out of the south and east under 5 kts. Commonly cooler locations could touch freezing briefly before dawn and frost is likely for many north of Highway 84. Southerly winds will become more established heading into Sunday ahead of an upper trough that will be moving across the area. With dry air in place, only some increase in cloudiness is expected and the attendant cold front will likely stall north of our area.
Key Messages: * Warmer temperatures and dry conditions continue through the weekend.
1213 PM EST Sat Feb 4 2023 High pressure shifts east this afternoon into tonight. Basically, temperatures will be warmer tonight by 10F-15F and Sunday by 10F as compared to last night and today. High temperatures Sunday will run from the upper 40s to the lower 50s.
1206 PM CST Sat Feb 4 2023 (Today through Sunday Night ) Sfc ridging will shift east of the area and winds will become srly across the state today.
Southerly surface winds will stay gusty ahead of the trough but will weaken and veer to the west-northwest behind the boundary this evening and tonight. Surface and upper level ridging will dominate the pattern in the central US tomorrow, making for a very nice February day with sunny skies, light winds and temperatures near 60 degrees for much of the area.
1220 PM EST Sat Feb 4 2023 High pressure brings dry weather through the weekend.
1240 PM EST Sat Feb 4 2023 Aviation -- First chance for precipitation Sunday into Sunday night -- A cold front will sweep into the area on Sunday and move south of the area Sunday night.

Clear and calm conditions will prevail today as high pressure dominates the pattern across the Southeast.
(This afternoon through Sunday) With deep ridging in place over the East CONUS, a broad area of stable, dry air is situated across the region. Temperatures will trend warmer as surface winds become southeasterly with highs in the 50s today then 60s tomorrow.
A chilly start this morning is seeing a quick warm up with temperatures near to below freezing bumping up to near 40 F as we approach 10 am. Under this axis of high pressure, lighter winds have allowed for temperatures to fall into the upper 20s so far. A few degrees of further cooling are possible before sunrise, and temps should be near at or below freezing across the board for daybreak. /NF/ A nice day is on tap for Sunday, with highs climbing into the mid 60s over most of the area as, high pressure continues to prevail over the area.
Above normal temperatures in the short term The upper level ridge has continued to flatten out today, resulting in tranquil wx as high level cirrus quietly streams overhead. Temps will be above normal again tomorrow as we remain in a dominant WAA pattern, with forecast highs in the low to mid 50s.
