Highs may struggle to reach the lower 40s across portions of southeast KS. A mid/upper ridge is progged to translate over the central CONUS in the wake of this trough bringing a return of mild and dry weather conditions through the weekend.
1239 AM MST Fri Feb 10 2023 High pressure will control the weather through the weekend and bring dry conditions through the period. With the higher sun angle and snow cover older now with less albedo, it may get a little warmer.
Otherwise, clear skies will cooler temperatures tonight with lows in the single digits to teens. Upper level ridging will also build over the area tonight and a warm front approaches from the west. On Friday the aforementioned warm front pushes through all of western and central ND.
1055 PM MST Thu Feb 9 2023 Upper level ridge with axis extending NE across the Northern Rockies this evening will shift east across the state through Friday morning, maintaining dry conditions with an increase in mainly high cloud-cover across the area tonight as moisture spills over the ridge. Gusty winds persist across areas adjacent to the Rocky Mtn Front and up through the Madison River valley with an uptick in winds likely in these areas late tonight through Friday morning as the surface pressure gradient strengthens and ridgetop winds increase some.
Cooler, but still above normal temperatures are expected Friday with a slight chance of precipitation during the afternoon. Latest progs show the cold front east of the ridges and cold air advection will continue through the rest of the night. Winds along the ridges remain elevated.
Currently - The Keys are within the western flank of deep layered ridging. Short Term Update - The ridge will remain stationary overnight. A ridge across Florida will maintain moderate to fresh east to southeasterly breezes across Keys waters through the overnight period.
An upper ridge will shift east tonight, followed by southwest flow aloft through Friday as a Pacific upper trough approaches the coast. Temperatures will be several degrees warmer as highs will reach into the lower 50s in some locations, including Boise.
450 AM EST Fri Feb 10 2023 A trough of low pressure will move through the region today with some lingering rain and snow showers through tonight.
(Today through Saturday afternoon) Light rain and snow showers have largely subsided across the Permian Basin this morning as the trough axis moves east of us and negative vorticity advection is underway. Clear skies and light winds set up efficient radiational cooling tonight, allowing low temperatures to fall into the low to mid 20s. Dewpoints will be in the low teens and single digits, so have undercut NBM a a degree or so. Upper ridging is set to build in on the heels of the departing trough with the ridge axis passing overhead Saturday afternoon.
Gusty northwest winds will bring cooler air into the region this morning, but milder air will start to return this afternoon. A ridge of high pressure will push through the region during the late afternoon and evening before sliding southeast of the region overnight. Used a blend of the warmer guidance sets for high temperatures.
Nonetheless, highs should climb into the mid 40s to the low 50s near and west of the Missouri River, and into the low to upper 30s further east (5 to 20 degrees above average).
Lift associated with the upper low will increase over Alabama Saturday and Saturday night, resulting in widespread rain. Highs today will be in the 50s and 60s, with cooler temperatures in the 50s on Saturday due to the rain and clouds.
A weak low pressure system will enter the area on Saturday, leading to slight rain chances for the San Joaquin Valley, as well as slight snow chances for the Sierra Nevada mountains. Our ridge of high pressure that has presented us with warm and dry conditions the past few days will continue through today.
Today and tonight: An upper-level trough axis will swing through the area before shifting off to the south and east this evening. The southern end of the trough axis is progged to develop into a closed upper low along the Gulf Coast later this evening and overnight.
556 AM CST Fri Feb 10 2023 (Today and tonight) An upper level trough will move across the area today and close off into an upper low over east Texas by tonight, with an upper level ridge building across the Rockies. At the surface, high pressure will settle over the area later today into tonight.
542 AM EST Fri Feb 10 2023 A cold front will cross over the Mid Atlantic today but stall along the East Coast tonight.
521 AM CST Fri Feb 10 2023 (Today through Saturday afternoon) Light rain and snow showers have largely subsided across the Permian Basin this morning as the trough axis moves east of us and negative vorticity advection is underway. Clear skies and light winds set up efficient radiational cooling tonight, allowing low temperatures to fall into the low to mid 20s. Dewpoints will be in the low teens and single digits, so have undercut NBM a a degree or so. Upper ridging is set to build in on the heels of the departing trough with the ridge axis passing overhead Saturday afternoon.
635 AM EST Fri Feb 10 2023 A trough of low pressure will move through the region today with some lingering rain and snow showers through tonight.
505 AM EST Fri Feb 10 2023 Cooler, but still above normal temperatures are expected today with a slight chance of precipitation during the afternoon mainly in the north. A brief bout of high pressure will keep conditions on Saturday dry. Latest progs show the cold front well east of the ridges and cold air advection will continue through dawn. Winds will remain elevated through dawn but the deep mixing has ended and winds will be sub Advisory in the low lands and thus the Advisory has been cancelled. The rest of the Advisory will remain in effect in the higher terrain through 12Z. Thanks to those cold 850mb temperatures, Saturday will be the coldest day of the forecast period, but with zonal flow just north of a Deep South cutoff upper low, this "cold" will be limited to seasonable temperatures.
It will be a little cooler today, but still with high temperatures mostly in the 70s for the coast and valleys.
The most robust activity is currently located north of the Lower Keys over the Bayside/Gulfside coastal waters. The mean layer ridge was located east of Bermuda this morning with the east to southeast flow continuing on its western periphery. As it approaches the coast overnight (11/06z), the 500 mb trough will develop a closed low while still remaining positively tilted. The cold front approaches the Florida Keys on Saturday pushing through the Keys Saturday night.
Confidence is on the lower end of seeing temperatures reach past 40 degrees tomorrow, the past several days guidance has been trended little higher than what actual temperatures reach so decided to stay conservative with highs, especially since there still continues to be decent snowpack lingering across portions of western and northwest Nebraska. Temperatures should be warmer on Saturday, with upper level ridging with highs reaching near to slightly above normal, which is in the low 40s this time of year.
515 AM CST Fri Feb 10 2023 High pressure building into the Midwest will foster dry and seasonably cool weather across central Illinois through the first half of the weekend.
Our coldest spots, near Devils Lake, will see temperatures near freezing while the warmest temperatures will reach 40 degrees near Bemidji.
307 AM CST Fri Feb 10 2023 A colder air mass was gradually working into eastern Iowa and northwest Illinois behind a departing area of low pressure now located in eastern Canada. Temperatures have fallen into the lower 20s in the NW (near Vinton and Independence), but were hanging on in the low/mid 30s along and east of the Mississippi River.
(Today and tonight) Snow activity has decreased drastically over the past two hours and is expected to continue decreasing as the axis of the upper trough pushes to our east. Skies should also begin to clear as snow showers and the trough axis move to our east. The upper trough will transition to a closed low as it moves off to our southeast and, partly as a result, will begin to slow in forward speed. Upper ridging will move over New Mexico tonight and remain just to our west by sunrise tomorrow morning.
250 AM MST Fri Feb 10 2023 Quiet weather day across the area as an upper level ridge moves over the Central Rockies. Saturday and Saturday night look to be dry and warmer than normal with upper ridging over the forecast area.
After a "cooler" Friday, generally above normal temperatures through the weekend.
602 AM CST Fri Feb 10 2023 An upper low will track through the region through Saturday night bringing colder temperatures a chance of showers to parts of east-central Arkansas and north Mississippi.
526 AM CST Fri Feb 10 2023 (Today through Saturday) Just after midnight, a cold front was located east of I-35 spanning from the NE to SW across the Coastal Plains, expected to exit south central Texas early this morning. Winds continue to decrease during the evening hours as high pressure begins to move in from the northwest. Cooler temperatures are forecast Saturday with highs from the mid 50s to the northeast, to the mid 60s over the southwest portion of the area.
640 AM EST Fri Feb 10 2023 A trough of low pressure will move through the region today with some lingering rain and snow showers through tonight.
The high pressure ridge transitions to southwesterly flow today as a trough digs down the West Coast. The moisture shifts southward tonight into Saturday as a weak trough moves through the Northern Rockies but once again precipitation will be very light and focused on the terrain.
an upper level ridge axis will approach the area from the west today, moving over the area tonight. High temperatures are forecast to be in the middle 30s to middle 40s with low temperatures in the lower teens to around 20. the ridge axis remains over the area during the day with an increase in high clouds during the afternoon. Low temperatures are forecast to be in the lower to upper 20s.
(Rest of Today) The Tennessee Valley sits in between two systems this morning with a cold front draped along the East Coast and a low pressure center spinning over the OK/TX border. Albeit, a bit cooler day than yesterday thanks to northerly flow, but afternoon highs will still rise into the mid to upper 50s.
423 AM EST Fri Feb 10 2023 Breezy and cooler with rain or snow showers over the Allegheny Mountains through tonight.
533 AM EST Fri Feb 10 2023 Cooler, but still above normal temperatures are expected today with a slight chance of precipitation during the afternoon mainly in the north. A brief bout of high pressure will keep conditions on Saturday dry. Latest progs show the cold front well east of the ridges and cold air advection will continue through dawn. Winds will remain elevated through dawn but the deep mixing has ended and winds will be sub Advisory in the low lands and thus the Advisory has been cancelled.

201 AM MST Fri Feb 10 2023 Upper level ridge moves into the area keeping things dry with temperatures well above average.
338 AM MST Fri Feb 10 2023 Most recent surface analysis shows high pressure to the south of the forecast area. At the upper levels, strong upper ridge sits over the Rockies with a positively tilted trough digging from the Great Lakes down into the central US. Mild southwesterly winds will continue through the day with above normal high temperatures as the ridge slides over the northern plains.
425 AM MST Fri Feb 10 2023 High pressure will control the weather through the weekend and bring dry conditions through the period. With the higher sun angle and snow cover older now with less albedo, it may get a little warmer.
Northerly surface winds will keep high temperatures several degrees cooler than yesterday and a nearby upper low will bring in additional cloud cover throughout the day. Precip will stay far to our west as this low becomes cutoff and dips to our southwest overnight tonight. Temperatures look to top out in the low 50s Saturday afternoon.
940 AM EST Fri Feb 10 2023 A cold front will stall along the East Coast tonight.
505 AM CST Fri Feb 10 2023 (Today and tonight) Snow activity has decreased drastically over the past two hours and is expected to continue decreasing as the axis of the upper trough pushes to our east. Skies should also begin to clear as snow showers and the trough axis move to our east. The upper trough will transition to a closed low as it moves off to our southeast and, partly as a result, will begin to slow in forward speed. Upper ridging will move over New Mexico tonight and remain just to our west by sunrise tomorrow morning.
(Now through Saturday) Latest surface analysis shows a cold front extending from north of Laredo to southeast of San Antonio. The frontal passage will be mainly dry, however, some shower activity and a possible rumble of thunder could develop over the lower Valley, coastal sections, and the marine areas. In the wake of the front, cooler and drier air will filter into the region. Today will be breezy with highs in the low to mid 60s with a mix of sun and clouds. Can't rule out an isolated freezing temperature here or there.

(Today and tonight) An upper level trough will move across the area today and close off into an upper low over east Texas by tonight, with an upper level ridge building across the Rockies. At the surface, high pressure will settle over the area later today into tonight.
644 AM EST Fri Feb 10 2023 High pressure will build into the region over the next couple of days.
520 AM CST Fri Feb 10 2023 (Today and Tonight) The forecast focus today is on the potential for minor snow accumulations primarily across the Ouachitas in southeast Oklahoma in association with the upper trough currently positioned across eastern New Mexico and West Texas. Temperatures in the higher elevations support at least a rain/snow mix through much of the day, with even the lower elevations seeing some snow potential into the evening.
1130 AM CST Fri Feb 10 2023 An upper low will track through the region through Saturday night bringing colder temperatures a chance of showers to parts of east-central Arkansas and north Mississippi.
1121 AM CST Fri Feb 10 2023 (Today and tonight) An upper level trough will move across the area today and close off into an upper low over east Texas by tonight, with an upper level ridge building across the Rockies. At the surface, high pressure will settle over the area later today into tonight.
Temperatures are near 80 with dewpoints in the lower 70s. High pressure centered near Bermuda continues to recede to the east today, meanwhile, a frontal boundary currently stalled over the Gulf of Mexico will reinvigorate.
Another quiet afternoon across eastern Idaho although we are seeing gradually increasing cloud cover as an upper-level ridge begins to give way to more a trough moving into the Pacific NW. These clouds SHOULD help to keep overnight lows warmer than what we've seen the past few days. Saturday highs look "milder" than what we've seen recently with much of the area likely to get above freezing with maybe some low 40s sneaking into the lower Snake and eastern Magic Valley.
A positively tilted upper level trough remains draped across the eastern half of the CONUS this morning as it slowly slides east with time. An upper level low will begin to pinch off this afternoon into this evening as the southern portion of the trough slides toward the ArkLaTex region. This upper low will gradually move east across the northern Gulf Coast and Deep South throughout the morning hours on Saturday before lifting into the Southeast in the short term timeframe. In the lower levels, the front will gradually sink further southeast across the Gulf today and tonight. A wave of low pressure will likely develop late tonight south of our Gulf waters and slowly lift northeast across the Gulf on Saturday. The HIGH risk may be able to be lowered later this morning dependent on lifeguard and beach reports.
1109 AM CST Fri Feb 10 2023 Cool high pressure is building into the Central Plains today behind an upper trough digging into Texas. This trough will cut off from the northern stream flow and slowly track near the Gulf Coast this weekend. We will be north of the trough in a subsident flow regime downstream of a developing ridge. This spells dry weather and an eventual shift toward warmer temperatures. For today, low level clouds have moved in from the north associated with an area of low level moisture at the leading edge of the cooler air. Tonight will be the coldest night of this forecast, with the core of the cold air over us and high pressure bringing light winds under a clear sky. We'll drop into the teens in the cold spots and in the low 20s elsewhere.
1257 PM EST Fri Feb 10 2023 Cooler, but still above normal temperatures are expected today with a slight chance of precipitation during the afternoon and early evening. Guidance has shown good continuity in progging a closed low to stay largely south and east of the forecast area, while the region remains under zonal flow aloft.
(The rest of today ) Upper trough axis continues to slide E-SE across Oklahoma this morning, with most precip confined to SE OK and WC AR. Upper trough will strengthen some as it continues to move through the forecast area, and this will likely keep precipitation going in the aforementioned areas through the afternoon. Rain will mix with snow at times, with all snow at times during the afternoon in the higher elevations of SE OK. Parts of the area will see sun this afternoon in the wake of the departing trough axis.
1125 AM CST Fri Feb 10 2023 (Today and tonight) Snow activity has decreased drastically over the past two hours and is expected to continue decreasing as the axis of the upper trough pushes to our east. Skies should also begin to clear as snow showers and the trough axis move to our east. The upper trough will transition to a closed low as it moves off to our southeast and, partly as a result, will begin to slow in forward speed. Upper ridging will move over New Mexico tonight and remain just to our west by sunrise tomorrow morning.
After several delays in timing from guidance, the cooler and drier air, coupled with strong northwesterly breezes will arrive Saturday night.
Tonight and Saturday Dry air and subsidence associated with surface ridging cleared out skies across the area through the morning hours, bringing in a sunny day for the region. Surface ridging will keep quiet and dry conditions in place through the remainder of the day and through the overnight hours. As the ridge departs to the east overnight, winds at the surface will shift over to the south and bringing back some relatively warmer aloft. Thus, seems likely we'll see a non-diurnal trend in overnight low temperatures, with the low being sometime shortly after midnight and then slowly increasing before sunrise.
At the surface, high pressure extends from West TX into Southwest IA. Cutoff upper low will sink down into the Arklatex region tonight into Sat morning with upper ridging building from the Rockies into the High Plains. For Sun, upper ridge will slide over the Plains as another upper low dives down over Southern CA.
(Tonight) A low pressure system along the OK/TX border will drop south and east tonight towards the Gulf Coast. The only other thing of note tonight is winds will stay elevated around 10 to 15 mph as the low pressure system gets closer to the area.
An upper level low pressure system will track from the Southern Plains through the Lower Mississippi Valley then northeastward into the Appalachians by Saturday Night. As the upper low tracks toward the Appalachians, rain will begin to spread northeastward into areas of West Tennessee near the Tennessee River and Northeast Mississippi Saturday afternoon into Saturday Night.
1222 PM EST Fri Feb 10 2023 High pressure will build into the region over the next couple of days.
On Saturday morning, as the cold front approaches, cloud cover will be increasing, keeping mostly cloudy conditions before becoming overcast in the afternoon.
A somewhat nebulous surface pattern looks to develop across the region with elongated high pressure across the Ohio River Valley and a weak cyclone moving far to our north near Hudson Bay.
Highs will be slightly cooler today, ranging in the upper 50s to mid 60s.
1116 AM CST Fri Feb 10 2023 (Rest of Today) The Tennessee Valley sits in between two systems this morning with a cold front draped along the East Coast and a low pressure center spinning over the OK/TX border. Albeit, a bit cooler day than yesterday thanks to northerly flow, but afternoon highs will still rise into the mid to upper 50s.
1140 AM CST Fri Feb 10 2023 An upper level low currently located over the Southern Plains will track eastward into the Lower Mississippi Valley by Saturday. Clouds associated with the upper low will continue to spread into the Mid-South today. KRM An upper low will track through the region through Saturday night bringing colder temperatures a chance of showers to parts of east-central Arkansas and north Mississippi.
1010 AM MST Fri Feb 10 2023 Most recent surface analysis shows high pressure to the south of the forecast area. At the upper levels, strong upper ridge sits over the Rockies with a positively tilted trough digging from the Great Lakes down into the central US. Mild southwesterly winds will continue through the day with above normal high temperatures as the ridge slides over the northern plains.
Temperatures dip to near seasonal normals for the weekend, but temperatures will begin to trend warmer into the next work week.
The higher elevation of the Buffalo Ridge area may allow them to tap into some of the stronger winds above the inversion.
1148 AM CST Fri Feb 10 2023 (Today through Saturday afternoon) Light rain and snow showers have largely subsided across the Permian Basin this morning as the trough axis moves east of us and negative vorticity advection is underway. Clear skies and light winds set up efficient radiational cooling tonight, allowing low temperatures to fall into the low to mid 20s. Dewpoints will be in the low teens and single digits, so have undercut NBM a a degree or so. Upper ridging is set to build in on the heels of the departing trough with the ridge axis passing overhead Saturday afternoon.
