Temperatures continue to drop in the wake of a cold front that pushed through in the past few hours, and lows will reach the low to mid 30s by sunrise. (This afternoon through Wednesday Night) With passage of surface frontal system as remainder of today progress, an upper level low will move across Upper Cumberland Region as evening hours approach and through early overnight hours tonight. " Dry conditions will prevail from late evening hours tonight through Wednesday per building ridging influences surface and aloft. Lows tonight will be slightly warmer than those experienced this morning, mainly in mid 30s. Lows once again will fall below freezing on Wednesday night, with lowest lows in mid 20s higher elevations of Upper Cumberland Region.
658 PM EST Tue Jan 30 2024 Upper trough from the Great Lakes region will continue to drop SSEward tonight then thru the Carolinas Wed. To end the week, minor upper ridging is expected to move through the region as the low level flow becomes easterly slowly moderating temps and moisture into the weekend.
Pronounced ridge axis continues to build into the Western Great Lakes region in the wake of this departing system. It looks like we start off with the low clouds in most areas (there could be lingering areas of fog as well). An increasing southwest flow is then likely to mix out at least some of the low stuff during the day leading to partly sunny skies in most areas (hopefully).
439 PM CST Tue Jan 30 2024 (Tonight) Cloud cover has begun to increase across TN as a cold front pushes south and east through the Tennessee Valley.
This is happening just south of a weak and dry cold front that will be advancing south through the Four State Region tonight. The air mass behind the front is not terribly chilly at all and a good deal of sun tomorrow should be able to deliver mild highs ranging from the lower 60s to around 70 degrees, which is at least 5 degrees cooler than the region is experiencing today.
535 PM CST Tue Jan 30 2024 (Tonight through Wednesday night) An H5 ridge sharpens over TX in the short term. Upstream from this ridge, upper troughing in the Eastern Pacific is funneling up some scattered high clouds while a weak pressure gradient at the surface holds the dry low level air in place. The result is warmer than normal temperatures in the afternoon and near normal morning temperatures. As the upper ridge nudges east Wednesday, the light and shifty surface winds become a bit more organized out of the SE but still remain light.

203 PM MST Tue Jan 30 2024 A modest pressure gradient is currently set up over south-central MT, allowing surface winds to gust around 30 mph across the lower elevations, but with localized gusts into the low 40s around the Livingston area.
218 PM MST Tue Jan 30 2024 An upper ridge over Montana is allowing for near record warm temperatures this afternoon.
Mature low pressure continues moving slowly across the Great Lakes this afternoon with the inbound mid level dry slot taking over the larger scale pattern. West wind manages to lift high temperatures into the lower 40s across the area despite the absence of sunshine.
================================================================= Upper low has dropped into the Smokies, but cyclonic curvature in the mid-level flow persists across Kentucky and southeast Indiana. Saturated boundary layer is just deep enough to have ice aloft, but sfc temps remain above freezing. The light precip could linger a bit past daybreak, but overall the trend for today will be dry as ridging tries to build in from the west. Thu morning lows will be just either side of freezing. ================================================================== Key Messages: * Warmer and dry end of week and start of the week.
The going forecast leans toward a cloudier solution with highs struggling to reach into the lower 40s though if more breaks in the clouds develop temperatures could easily warm into the mid 40s. This resulted in a slightly warmer solution with even some small breaks in clouds this afternoon. Will continue isolated shower mention in the forecast through mid-evening An unseasonably strong mid-level ridge across the Rockies today will drift eastward across the central Great Plains while slowly suppressing southward through Wednesday.
155 AM MST Wed Jan 31 2024 Near record highs will continue through the short term under the upper level ridge.
/Issued 1219 AM CST Wed Jan 31 2024/ /Through Wednesday Night/ Mid-level ridging building overhead will allow for a quiet forecast with pleasant conditions through the midweek period. Another abnormally warm day is expected on Wednesday with afternoon highs topping out in the low to mid 70s across much of North and Central Texas. Persistent low-level southerly flow and widespread high clouds will allow for a warmer Wednesday night.
1122 PM CST Tue Jan 30 2024 (Tonight) A cold front that has now exited southeast of the TN Valley has continued to keep low chances of showers (20% or less) through 04Z. These winds are forecast in response to a low level jet moving through our area as a trough axis (oriented NE to SW) swings through central AL and we experience NVA and CAA- allowing dry conditions to return.
Water vapor imagery highlights a mid-level trough digging southeast into the southern Appalachians. High pressure centered near the northwestern Gulf coast will maintain light breezes tonight through Wednesday morning. A reinforcing cold front will push through Keys waters late Wednesday, accompanied by briefly freshening northwesterlies.

1027 PM CST Tue Jan 30 2024 (This evening through Wednesday) Upper level ridging will result in above normal temperatures along with light winds across West Central Texas through the next 24 hours.
(Today) An area of low pressure was heading to the SE across the KY/WV border. A cold front trailing south of this low earlier swept across the Tennessee Valley. To the west of the low, more low to mid altitude stratus (cloud bases in the 3-5Kft AGL) were nearing the area from the NW.
Evening synoptic/sfc analysis indicate digging trough axis over the Mid South to TN Valley & progged to continue to swing southeast into the Appalachians-Carolinas by the morning. This will help cooler air filter into our region Wednesday with high temperatures in the 55 to 65 degree range. Mid to late week: An omega block over the CONUS will keep deep ridging for our area resulting in quiet weather through the end of this week with temperatures generally above normal during the day. These conditions will likely offer the chance to radiate overnight, thereby keeping overnight lows on the cooler side.
A trough and associated low pressure system currently located over the Ohio Valley will continue to dig southeastward, dragging a cold front across the Florida Peninsula today.
1213 AM EST Wed Jan 31 2024 An area of low pressure will move through the Carolinas late tonight through Wednesday bringing some light shower activity with it. High pressure will then rebuild across the region through the rest of the week. A band of scattered showers will move across much of southern South Carolina over overnight as a sharp upper trough approaches. Otherwise, temperatures will run cooler compared to today, ranging from the middle-upper 50s across the South Carolina counties to the lower 60s across southeast Georgia.
Afternoon highs will again warm to well above normal levels areawide, with upper level ridging overhead and plenty of sun.
(Today and tonight) Another warm and sunny day is in store across the area as a mid- level ridge continues to build over the central and southern Plains. Highs today will be in the low 70s for most locations, with light winds out of the south.
1054 PM CST Tue Jan 30 2024 (Tonight through Wednesday night) An H5 ridge sharpens over TX in the short term. Upstream from this ridge, upper troughing in the Eastern Pacific is funneling up some scattered high clouds while a weak pressure gradient at the surface holds the dry low level air in place. The result is warmer than normal temperatures in the afternoon and near normal morning temperatures. As the upper ridge nudges east Wednesday, the light and shifty surface winds become a bit more organized out of the SE but still remain light.
1253 AM EST Wed Jan 31 2024 Following a few lingering rain or snow showers in northern West Virginia, high pressure will build in from the west providing a dry rest of the day. - Light snow accumulations possible in the West Virginia ridges. The main upper low will dive southward to the west of the region keeping the best lift well west of the area as well.
There will be a few showers/sprinkles around with light snow showers/flurries over the higher elevations mainly north and east to start the day, but these will quickly end during the morning hours.
(Tonight) A cold front that has now exited southeast of the TN Valley has continued to keep low chances of showers (20% or less) through 04Z. These winds are forecast in response to a low level jet moving through our area as a trough axis (oriented NE to SW) swings through central AL and we experience NVA and CAA- allowing dry conditions to return.
946 PM CST Tue Jan 30 2024 03Z / 9PM CST surface map shows a cold front just south of Monroe county MS, out of the forecast area. 9Î¼m imagery shows stratocumulus over eastern MO, moving southeast behind an upper level trough over middle TN. PWB High pressure will build into the region tonight bringing cooler and drier air.
Patchy light freezing drizzle/wintry mix can't be completely ruled out where temperatures permit. Sfc temperatures are largely above freezing as of right now supporting liquid phase, but we may see temperatures dip enough before the activity ends after midnight to some light freezing drizzle/wintry mix reported in a few spots. CMiller Issued 232 PM CST Tue Jan 30 2024 Tonight through Wednesday night: As drizzle and perhaps a couple snowflakes move out of the area this afternoon behind a filling low, expect winds to decrease and temperatures to begin to fall overnight to just below freezing. The highest temperatures will be dependent on how quickly the cloud deck whittles away. Wednesday night, expect lows just above freezing, with a few spots in the Kettle Moraine falling to 32 degrees.
121 AM MST Wed Jan 31 2024 - Another dry and mild day, with high pressure remaining in place. Fog has once again formed over the cooler basins and valleys.
Winds will turn northwesterly by midday and increase with gusts of 20 to 25 kts as a cold front passes over the region.
1057 PM EST Tue Jan 30 2024 A weak area of low pressure will track well south of Pennsylvania tonight.
1052 PM CST Tue Jan 30 2024 (This evening through Wednesday night) Dry weather along with above normal to well above normal temperatures will persist through Wednesday night as an upper level ridge of high pressure moves across and to the east of the plains states.
1121 PM CST Tue Jan 30 2024 03Z / 9PM CST surface map shows a cold front just south of Monroe county MS, out of the forecast area. 9Î¼m imagery shows stratocumulus over eastern MO, moving southeast behind an upper level trough over middle TN.

1126 PM CST Tue Jan 30 2024 (Tonight) A cold front that has now exited southeast of the TN Valley has continued to keep low chances of showers (20% or less) through 04Z. These winds are forecast in response to a low level jet moving through our area as a trough axis (oriented NE to SW) swings through central AL and we experience NVA and CAA- allowing dry conditions to return.
354 AM EST Wed Jan 31 2024 Following a few lingering rain or snow showers in the higher elevations, high pressure will build in from the west providing a dry rest of the day.
526 AM CST Wed Jan 31 2024 Today and Tonight: Dry through the period with near normal highs today and slightly cooler than normal temperatures tonight. Early morning satellite imagery/RAP analysis showed the circulation around a closed low spinning over the southern Appalachians. The resulting northwest flow aloft across our region was helping a dry cold front move through our CWA. Early morning surface analysis had this dry cold front generally along and south of Interstate 20. In the wake of the cold front today temperatures will be held in the 50s north of I-20 and in the low to mid 60s south. Tonight, near ideal radiational cooling will help temperatures bottom out below freezing in our northeast and in the 30s elsewhere.
513 AM EST Wed Jan 31 2024 Following a few lingering rain or snow showers in the higher elevations, high pressure will build in from the west providing a dry rest of the day.
(Today through Thursday Night) The cold front that passed southward acrs AR on Tue ushered in a reinforcing shot of cooler and drier air. These clouds were assocd with cyclonic flow arnd an upper low ovr eastern TN. Contd to trend a few degrees warmer than the NBM guidance, which has been on the cooler side the last few days. As the high shifts to our east on Thu, south winds wl return, with high temps in the 60s ovr much of the Natural State.
pdf Northwesterly winds will build this afternoon as a reinforcing dry cold front moves in over the region from out of the north today ensuring a continuation of dry weather, mostly clear skies, and cool temperatures through today and into early Thursday as high pressure settles across the region. High temperatures will be in the 60s with warmer temps occurring further to the south. Overnight low temperatures will drop down into the mid to upper 30s for for inland areas and in the low to mid 40s for areas near the coastline.
447 AM CST Wed Jan 31 2024 (Today) An area of low pressure was heading to the SE across the KY/WV border. A cold front trailing south of this low earlier swept across the Tennessee Valley. To the west of the low, more low to mid altitude stratus (cloud bases in the 3-5Kft AGL) were nearing the area from the NW.
================================================================= Upper low has dropped into the Smokies, but cyclonic curvature in the mid-level flow persists across Kentucky and southeast Indiana. Saturated boundary layer is just deep enough to have ice aloft, but sfc temps remain above freezing. The light precip could linger a bit past daybreak, but overall the trend for today will be dry as ridging tries to build in from the west.
This air mass will stretch thin across I-20, so highs today will be cooler mid to upper 60s east of I-49. The VAD shows N winds in the lower few thousand feet and our N/NE winds will lower dew points and heights aloft compared to yesterday.
A ridge of high pressure building into the state this afternoon will help to generate a light westerly low level flow of relatively drier air.
320 AM CST Wed Jan 31 2024 Today and Tonight: Dry through the period with near normal highs today and slightly cooler than normal temperatures tonight. Early morning satellite imagery/RAP analysis showed the circulation around a closed low spinning over the southern Appalachians. The resulting northwest flow aloft across our region was helping a dry cold front move through our CWA. Early morning surface analysis had this dry cold front generally along and south of Interstate 20. In the wake of the cold front today temperatures will be held in the 50s north of I-20 and in the low to mid 60s south. Tonight, near ideal radiational cooling will help temperatures bottom out below freezing in our northeast and in the 30s elsewhere.
As a result, the clouds will remain locked in place this morning and will only gradually dissipate/clear from southwest to northeast this afternoon as the high drops into the Ozarks and boundary layer flow becomes southwesterly. Further east, areas east of I-57 will stay mostly cloudy through the entire day and will be a bit cooler in the lower 40s. Clouds will be on the increase on Thursday in advance of a weak cold front dropping out of the Northern Plains: however, given partial sunshine and southwesterly flow, high temperatures will climb into the lower to middle 50s.
High temperatures today will remain below normal, with much of the area remaining in the low to mid 40s. Good news though, high pressure will move into the area by early tomorrow, allowing for sunshine to finally return.
With temperatures a few degrees cooler this morning, hovering in the mid-20s, the freezing fog persists, creating icy conditions and significantly reducing visibility. Freezing fog advisories are still in effect through this morning, underscoring the need for extra travel time. Looking ahead, low pressure gradually advancing into the Pacific Northwest is poised to enter the region on Thursday, ushering in escalating shower chances from west to east, particularly in north-central Idaho by Thursday afternoon.
Meanwhile, a mid/upper ridge will translate eastward into the central CONUS resulting in mild, above average temperatures across the area today and Thursday.
Upper level ridge begins to shift to the east and weak disturbance begins to move in from Mexico. Tonight ends up milder than this morning with most areas in the low 40s and a few colder spots reaching into the upper 30s.
- Chance of drizzle/freezing drizzle tonight and drizzle on Thursday.
After sunrise, the low clouds are expected to break apart / scatter as the 500mb ridge builds in, with daytime highs in the low 40s. Low moisture continues to linger tonight, suggesting that the low stratus may rebuild and hinder fog formation early Thursday morning. Daytime highs remain in the low to mid 40s Thursday, with dry weather.
The deep ridging that has been over the region will be starting a slow slide east the next couple of days. This will translate to a slow return of low-level moisture and clouds as warmer temperatures persist. With partly to mostly cloudy skies, highs today will run in the lower 70s for most locations. As mid/ high cloud cover increases tomorrow, highs could run a degree (or so) cooler, in the upper 60s to around 70. Chances for fog should be more favorable tomorrow night as temperatures and dewpoints increase (into the lower to mid 50s).
Currently - Baggy high pressure over the Gulf of Mexico is driving light northwest to northerly breezes across the Keys early this morning. Temperatures are in the lower 60s with dew points ranging broadly in the lower 50s. Skies are mostly clear, but patches of stratocumulus are becoming more predominant over and west of the Lower and Middle Keys. In response, winds will freshen modestly out of the northwest and north this afternoon and evening and ultimately bring a dry reinforcing cold front through the Keys. This front will essentially hold things where they have been with highs in the upper 60s, lows ranging near 60, and dew points holding in the lower 50s. This high will slowly build southeastward through the remainder of the week.
There may be a few freezing to sub freezing temperatures this morning and again tomorrow(Thursday) morning, but the remainder of the forecast is warmer.
High temperatures could be a couple degrees warmer than today, as there should be more sunshine than the last several days.
Warm and dry weather continues today as an upper level ridge builds over the area.
This will help reinforce the cool air mass currently in place over the region, prolonging this period of cooler than average temperatures. Behind the front, high pressure will build over the region. High temperatures each afternoon will hover around the low 70s, while overnight temperatures Wednesday into Thursday could drop to the mid 40s over the interior and southwest FL and the lower 50s along the East Coast.
511 AM CST Wed Jan 31 2024 (Today through Thursday) A cold front has pushed to near the I-85 corridor early this morning. Despite plenty of sunshine, highs today will be about ten degrees cooler than yesterday. A nice warm-up on Thursday as an upper ridge builds over the area with highs in the lower to middle 60s.
(Today through Thursday night) Model agreement is still trending for a ridge and dry weather to close out the last remaining days of January here in the Panhandles. While this trough will see cloud cover develop over the Panhandles, it will also aid in the generation of a lee-side low off the southern portion of the Front Range. This low will be enough to see winds pick back up across the panhandle and return us to our usual breezy self. On Thursday in particular, the low will shift just enough to induce some downsloping southwesterly winds to our south, which will further aid in the heating of the Panhandles that afternoon. As it stands, look for Thursday to be our hottest day of the week with afternoon high temperatures potentially in the high 60s to low 70s.
More warm temperatures are on the way for the short term period as a 500mb ridge builds over Missouri. Clouds start to move in west to east after midnight which will keep low temperatures a bit warmer than the previous night in the mid 40s for west of highway 65 and mid 30s where there will be less cloud cover east of highway 65.
(Today and tonight) The upper level ridge will begin to shift to the east and winds at the surface will turn more to the south this afternoon. The continued upper level ridging and warm air advection will allow for another day of above normal temperatures, with highs primarily in the 70s. As the ridge nudges east, winds aloft will turn southwest. The south winds and overcast skies will leave temperatures about 5 to 10 degrees warmer tonight compared to last night. However, with the drier nature of the low to mid levels virga is possible with any precipitation, leaving very little rain accumulation, if any.
625 AM EST Wed Jan 31 2024 A low pressure system moves east of the area today with diminishing precipitation and clearing skies. High pressure returns Thursday with a warming trend.
Pattern Synopsis: Ridging will continue to slide over the Great Lakes today and work over the Mid-Atlantic tonight. Forcing provided by this feature aloft will support a weak cyclone that looks to trek across Ontario into Quebec by the end of the period. As daytime heating ensues after sunrise, enough mixing should occur to dissipate fog across most areas by this afternoon -- despite continued warm air advection over an existing snowpack with air temperatures above freezing. Mild overnight lows in the upper 20s and low 30s are also anticipated, making for temperatures around 15-20 warmer than average through the forecast period to close out January.
The next reinforcing shot of dry air will move down behind a new backdoor cold front this morning.
518 AM CST Wed Jan 31 2024 (Today and tonight) The upper level ridge will begin to shift to the east and winds at the surface will turn more to the south this afternoon. The continued upper level ridging and warm air advection will allow for another day of above normal temperatures, with highs primarily in the 70s. As the ridge nudges east, winds aloft will turn southwest. The south winds and overcast skies will leave temperatures about 5 to 10 degrees warmer tonight compared to last night. However, with the drier nature of the low to mid levels virga is possible with any precipitation, leaving very little rain accumulation, if any.
447 AM CST Wed Jan 31 2024 (Today and tonight) Another warm and sunny day is in store across the area as a mid- level ridge continues to build over the central and southern Plains. Highs today will be in the low 70s for most locations, with light winds out of the south.
346 AM MST Wed Jan 31 2024 - Another dry and mild day, with high pressure remaining in place. Fog has once again formed over the cooler basins and valleys.
