Another sunny and warm day with above average temperatures with daytime highs in the low to mid 80's and overnight lows in the 60's expected today and tonight. A closed upper low and troughing over the central U. lends support to a developing area of low pressure south of the Great Lakes. The associated cold front will move eastward over the next 24-36 hours approaching the eastern gulf waters and Nature Coast on Friday morning. Scattered showers and storms can be expected ahead of and in the vicinity of the cold front through the day on Friday with the highest chances over the Nature Coast and northern Florida.
Temperatures tonight will drop quick, with lows decreasing down to the low to mid 30s along areas north of I-10, the mid to upper 30s along areas south of I-10, and the low 40s along the coasts. Some isolated spots in and around the Burleson, Brazos, Madison, and Houston counties could have a few hours of temperatures at or just below freezing. Thus, temperatures will feel even colder outdoors, possibly all the way down to the low to mid 20s around sunrise Friday. Cool conditions expected Friday with high temperatures in the low to mid 50s areawide. A little bit of moisture from the Gulf will begin to move in from the southwest, thus, some areas along the Matagorda/Jackson region could have lows a little warmer than the rest of the forecast area.
A little warmer than today although still below normal. Highs mainly in the low 50s.
238 PM CST Thu Feb 16 2023 Key Points: - Light snow tapers off by the evening - Returning to warm and dry weather for the weekend As the upper low has shifted eastward today, the dry air aloft that kept snow at bay last night has moved eastward as well. Snow should taper off early evening as the low continues eastward. Following this overnight, high pressure will move in overhead, allowing winds to calm and skies to clear. By tomorrow, we return to a warmer pattern as high pressure departs and southerly flow becomes reestablished.
1131 AM CST Thu Feb 16 2023 Quiet conditions continue across the region with latest observations showing increasing cloud cover ahead of an advancing upper level trough and low pressure near the Nebraska/Kansas border. Meanwhile at the sfc, will see a ridge axis slowly drift eastward throughout the day. Currently have gusts ranging from 15 to 25 mph, with those along the Buffalo Ridge approaching 30 to 35 mph at times.
1145 AM CST Thu Feb 16 2023 (The rest of today ) It will be a mostly cloudy and colder day across the region behind a cold front which is now moving into eastern AR. There may be a few breaks here and there but clouds will be stubborn to clear until Friday when the upper trough axis slides by.
1136 AM CST Thu Feb 16 2023 Showers and thunderstorms will lift through the Midsouth today, along and ahead of a slow-moving cold front. Following the passage of the cold front today, cooler and less humid weather will prevail over the Midsouth Friday and the weekend.
A strong cold front will sweep through the Keystone State late tonight through early Friday morning accompanied by another round of showers. Expect a band of showers along strong cold front tracking west to east through CPA after midnight into early Friday morning. Snow showers over the western mtns could bring a minor accumulation over the higher terrain through Friday night.
(This afternoon through Friday night) In the wake of last night's cold front, it's a downright chilly day across the region today, with temperatures on target to top out well below normal, in the 40s and lower 50s for most.
* Warmer weather is expected through the weekend, but areas with existing snowpack will still remain a few degrees cooler than areas that received little or no snow.
Tomorrow is forecasted to be warmer with clear skies continuing, the higher surface pressure moving out of the area and winds shifting to out of the southwest.
(This evening through Friday Night) The aforementioned sfc cold front has moved through the region, with falling temperatures behind it today. But, still expecting much cooler temps tonight, with most of the region falling into the upper 20s and lower 30s overnight. Much cooler temperatures and clearing skies will prevail on Friday, with lighter northerly winds and afternoon high temperatures mostly in the lower to middle 50s areawide.
Models have upper ridging to move into and across the CWA tonight and Friday with moderately strong wind speeds at jet level. The low level pressure gradient will be weak with troughing east of the mountains.
Key Points: - Light snow tapers off by the evening - Returning to warm and dry weather for the weekend As the upper low has shifted eastward today, the dry air aloft that kept snow at bay last night has moved eastward as well. Snow should taper off early evening as the low continues eastward. Following this overnight, high pressure will move in overhead, allowing winds to calm and skies to clear. By tomorrow, we return to a warmer pattern as high pressure departs and southerly flow becomes reestablished.
Although skies are expected to clear Friday with the axis of high pressure moving in, it will still be chilly with temperatures in the 20s and wind chills in the teens.
(This evening through Friday) Breezy north winds continue behind a cold front this afternoon, with a fairly tight pressure gradient remaining in place. Subfreezing lows are expected area wide, with teens likely along and north of I-40/I-44.
256 PM MST Thu Feb 16 2023 Ridging continues to build this afternoon, with clear skies and cold temperatures noted across the area. Tonight will be a bit warmer than this morning due to warmer air advecting in, but the basins, in particular, will still be quite cold. The ridge will break down Friday night as a broad trough starts to build in, bringing a northwest flow back to Wyoming.
/NEW/ /Tonight through Friday Night/ High pressure will continue to build into the Southern Plains tonight with a fairly tight pressure gradient remaining in place. Water vapor imagery shows the trailing trough axis spreading into the TX Panhandle while a 140 kt upper jet is streaming overhead. Despite modest forcing for ascent from the trough and some weak echoes on radar, moisture is generally confined to the upper levels, so no precipitation is expected. Winds will gradually diminish on Friday as high pressure settles into the region. Mostly sunny skies and temperatures in the lower 50s are expected with another cold night Friday night. Temperatures will fall to near freezing areawide. /Issued 249 PM CST Thu Feb 16 2023/ /Friday Night Onward/ Subsidence associated with the prevailing mid level ridging will maintain dry conditions across North and Central Texas into the weekend.
High pressure continues to sit across the silver state causing fair weather and light winds. The high pressure will lead to warming temperatures for our region. High pressure continues to be dominant across the silver state with fair weather and light winds. There will be an increase in mid to upper level clouds for today and tomorrow as the low cuts digs off the west coast. Temperatures under the high pressure will warm for both days with most areas going above freezing for highs starting on Friday.
242 PM MST Thu Feb 16 2023 High pressure shifts across the region tonight for continued dry conditions with increasing clouds through Friday morning. An upper level ridge extending north into western MT this afternoon will flatten later tonight as the northern portion of a splitting trough off the west coast moves into western Canada and east across AB/SK Friday.
Ridging is currently in place, but split flow will move in closer to the shore from the waters tonight. Otherwise, sub- freezing temperatures inland will start the morning with temperatures in the 20s on the west side and teens for the east side. Tonight, an area of low pressure starts to split southward of Oregon.
Upper level trough is still poised to the west, set to cross IL overnight, and frontogenesis associated with a deformation axis continues to bring a shield of snow across IA into WI and northern IL.
237 PM MST Thu Feb 16 2023 A ridge of high pressure over the Great Basin region will dominate the weather pattern tonight with clear conditions and unseasonably cold temperatures. Expect another round of frigid temperatures tonight under the ridge of high pressure with high valley locations dropping well below zero overnight. The ridge will slowly flatten and push east tomorrow and tomorrow night as a weak storm system impacts the Pacific northwest region. Expect high temperatures tomorrow to be around 10 degrees warmer than today but still well below normal for this time of year.
Over the Rockies into the Plains, this setup will allow the upper flow to flatten out, increasing lee troughing and providing strong south and southwest winds across the region for Sat. Both ECMWF and GFS have a closed low off of Baja by Mon morning with strong west/northwest flow aloft from the Rockies into the Midwest. As the southern stream upper low progresses east into West TX for Tue night into Wed, a much more robust upper trough will start to dig over the Western CONUS into the Great Basin.
In the mid levels the positively tilted mid level trough is currently moving through the area, with the trough axis moving east of the area in the next few hours. While the mid levels will support a calm and warming forecast it will take some doing at the lower levels to scour out the cold air that continues to trickle in behind northerly winds.
415 PM MST Thu Feb 16 2023 A ridge of high pressure over the Great Basin region will dominate the weather pattern tonight with clear conditions and unseasonably cold temperatures. Expect another round of frigid temperatures tonight under the ridge of high pressure with high valley locations dropping well below zero overnight. The ridge will slowly flatten and push east tomorrow and tomorrow night as a weak storm system impacts the Pacific northwest region. Expect high temperatures tomorrow to be around 10 degrees warmer than today but still well below normal for this time of year.
As the trough swings to the E tonight, ridging will build in the wake. Strong NW gradient winds are moving in the wake, with temperatures dropping into the low 50s in the NW to low 60s in the SE, outside of the Pine Belt in the low 70s just ahead of the sfc front. Lows will be chilly in the low 30s NW to low 40s SE. /DC/ Tonight through Friday: a cold front will continue pushing east through the remainder of the forecast area late this afternoon and early evening. /EC/ The cold front will have pushed east giving us cold and drier air throughout the weekend as a high pressure building over us will keep us at these conditions for a few days.
Pops will be kept on the low side for that area however.
528 PM CST Thu Feb 16 2023 (This afternoon through Friday night) In the wake of last night's cold front, it's a downright chilly day across the region today, with temperatures on target to top out well below normal, in the 40s and lower 50s for most.
(Now through Friday) Severe thunderstorms will remain possible through this evening as a cold front approaches the area. The risk of showers and storms will end from west to east after midnight as the cold front moves across the area.
805 PM EST Thu Feb 16 2023 Scattered showers will occur along a cold front as it crosses east through the Ohio Valley this evening. Dry and significantly colder air will rush in behind it, keeping highs on Friday only about a handful of degrees warmer than the morning low.
301 PM MST Thu Feb 16 2023 Current surface analysis shows frontal boundary/developing warm front from far eastern MT into western SD, with high pressure to the east-northeast of the region. A ridge is located across the Pacific NW, south- southwestward to NV and southern CA. Warming trend will continue late this week and into the weekend as flattening ridge over the western US moves east into the Plains. Frontal boundary over the area will continue to move slowly east- northeast as a warm front into Friday.
Mostly quiet and clear tonight with lows in the 60s before a cold front approaches the peninsula on Friday afternoon with breezy conditions developing over the area. Another sunny and warm day with above average temperatures with daytime highs in the low to mid 80's and overnight lows in the 60's expected today and tonight. A closed upper low and troughing over the central U. lends support to a developing area of low pressure south of the Great Lakes. The associated cold front will move eastward over the next 24-36 hours approaching the eastern gulf waters and Nature Coast on Friday morning. Scattered showers and storms can be expected ahead of and in the vicinity of the cold front through the day on Friday with the highest chances over the Nature Coast and northern Florida.
602 PM CST Thu Feb 16 2023 Upper level jet induced clouds forming over the Rockies of Alberta are rotating around a mid level ridge and being redirected southeast towards the north cental CONUS.
346 PM MST Thu Feb 16 2023 Ridging continues to build this afternoon, with clear skies and cold temperatures noted across the area. Tonight will be a bit warmer than this morning due to warmer air advecting in, but the basins, in particular, will still be quite cold. The ridge will break down Friday night as a broad trough starts to build in, bringing a northwest flow back to Wyoming.

542 PM CST Thu Feb 16 2023 (This evening through Friday Night) The aforementioned sfc cold front has moved through the region, with falling temperatures behind it today. But, still expecting much cooler temps tonight, with most of the region falling into the upper 20s and lower 30s overnight. Much cooler temperatures and clearing skies will prevail on Friday, with lighter northerly winds and afternoon high temperatures mostly in the lower to middle 50s areawide.
The northern half of the Golden State presently finds itself with an upper-level ridge overhead as yesterday's low has already ejected east into the Rockies.
724 PM EST Thu Feb 16 2023 A line of a showers and maybe some weak storms will push through Friday morning ahead of a cold front.
An area of low pressure will continue to drop south over the coastal waters tonight, mainly just bringing mid level clouds and southerly winds to the area.
455 PM CST Thu Feb 16 2023 Tonight through Friday: a cold front will continue pushing east through the remainder of the forecast area late this afternoon and early evening. /EC/ The cold front will have pushed east giving us cold and drier air throughout the weekend as a high pressure building over us will keep us at these conditions for a few days.
As the cold front crosses the southeastern CWA, a narrow corridor of sfc based CAPE could interact with the shear of the approaching front for a strong storm but very unlikely to reach severe limits. WINDS DECREASE FRIDAY EVENING AS HIGH PRESSURE NUDGES INTO THE AREA FROM THE WEST. BROAD MID LEVEL RIDGE ACROSS THE GULF STATES WITH A WESTERLY FLOW ACROSS THE OHIO VALLEY.
428 PM MST Thu Feb 16 2023 Current surface analysis shows frontal boundary/developing warm front from far eastern MT into western SD, with high pressure to the east-northeast of the region. A ridge is located across the Pacific NW, south- southwestward to NV and southern CA.

458 PM CST Thu Feb 16 2023 (This evening through Friday) Breezy north winds continue behind a cold front this afternoon, with a fairly tight pressure gradient remaining in place. Subfreezing lows are expected area wide, with teens likely along and north of I-40/I-44.
Today through Friday: An upper trough initially over the northeast Pacific will evolve into a closed low while dropping south across the eastern Pacific. Overnight readings will be a bit "warmer" with the high clouds around. Look for lows between 35 and 40 degrees for most areas, with the usual caveat that some inland valley spots could be a bit cooler while the SF Peninsula will be a bit warmer. As high clouds thin a bit on Friday look for highs to be a few degrees warmer and mostly in the lower 60s.
Upper level jet induced clouds forming over the Rockies of Alberta are rotating around a mid level ridge and being redirected southeast towards the north cental CONUS.
237 AM EST Fri Feb 17 2023 A line of a showers will push through the area today ahead of a cold front.
Slow moving mid level trough axis should allow clouds to persist much of the night for far E OK / NW AR with clearing further west. (Tomorrow through Thursday) Most of the forecast period will be marked by a break in the recent active weather pattern, with low amplitude ridging over the Southern Plains into the weekend.
937 PM CST Thu Feb 16 2023 A broad line of showers and isolated embedded thunderstorms presently moving through south central Louisiana will continue to push off to the east over the next couple of hours as the cold front responsible for the precipitation begins to accelerate once again. Strong CAA developing in the wake of the front is still expected to drop temperatures into the low to mid 30s overnight.
1023 PM CST Thu Feb 16 2023 (This afternoon through Friday night) In the wake of last night's cold front, it's a downright chilly day across the region today, with temperatures on target to top out well below normal, in the 40s and lower 50s for most.
Synopsis/Forecast: Current consolidated troughing is pushing into the lower Great Lakes early this morning. Cold today with highs mainly in the low 20s.
With temps still above freezing in the far east and southeast, any precip has been rain. Upper level trough is still poised to the west, set to cross IL overnight, and frontogenesis associated with a deformation axis continues to bring a shield of snow across IA into WI and northern IL.
1136 PM EST Thu Feb 16 2023 Showers will accompany an overnight cold front followed by falling temperatures and scattered light snow showers during the day. High pressure will then provide a dry and relatively mild weekend. A cold front currently over western OH will begin to cross the forecast area shortly after midnight and be east of the ridges by sunrise. The core of the colder airmass will move over the area by late Friday with lows dipping into the lower 20s.
Latest water vapor satellite imagery and RAP upper air analysis depict a typically amplified pattern for mid-February, with a positively tilted trough extending from the Great Lakes southwestward into the southern plains, and a ridge over the Intermountain West. At the surface, high pressure that is currently centered over east-central NM/west-central TX will slide eastward, turning winds across our area to the south-southwest at around 10-15 mph. These downsloping winds coupled with clear skies will result in a markedly warmer afternoon Friday, with highs in the mid 40s to low 50s.
An Atlantic ridge centered well east of the southeastern United States extends a ridge west southwestward across the Florida Peninsula and into the Gulf of Mexico. However, a small cluster did move through near the 7 Mile Bridge early this evening. A ridge across Florida will retreat further eastward through the overnight period.
Otherwise, The cold front has push into BHM EET and the front was undercutting the overall moisture. Improving conditions are forecast through the day on Friday as the surface cold front moves east of the area toward sunrise. High temperatures will be noticeably cooler with readings from the low 40s northwest to the mid 50s southeast.
122 AM MST Fri Feb 17 2023 Upper ridging sits over the Rockies, with a split trough over the west coast, and its low spinning off the coast of CA. As the northern part of the aforementioned trough scoots across the northern US today, NW winds will increase (but remain below advisory criteria) across NW SD.
303 AM EST Fri Feb 17 2023 Sfc cold front continues to push eastward through eastern KY this morning. In the wake of the sfc front, some mid-level frontogenisis around 700mb ahead of the main trough axis is working east-southeast across IN. These flakes, given how warm we've been the last few days and with temperatures above freezing, should not have much if any impacts during the morning commute. An embedded vortmax ahead of the trough will work across the Ohio Valley and with the shallow layer of moisture, a few flurries are possible through the day across most of the area.
(Today and tonight) High pressure settling in over much of West Central Texas today, along with continued cool northerly flow this morning and clear conditions will lead to below normal temperatures for today and tonight. Winds will begin to become more light and variable by this afternoon as the aforementioned high pressure centers over the area.
1129 PM CST Thu Feb 16 2023 A broad line of showers and isolated embedded thunderstorms presently moving through south central Louisiana will continue to push off to the east over the next couple of hours as the cold front responsible for the precipitation begins to accelerate once again. Strong CAA developing in the wake of the front is still expected to drop temperatures into the low to mid 30s overnight.
147 AM EST Fri Feb 17 2023 A line of a showers will push through the area today ahead of a cold front.
(Today and tonight) Today will start off cold with temperatures ranging from the low teens to the 20s at sunrise. Temperatures tonight will be warmer with lows in the 20s and 30s due to southerly winds and increasingly cloudy skies.
1142 PM CST Thu Feb 16 2023 (This evening through Friday) Breezy north winds continue behind a cold front this afternoon, with a fairly tight pressure gradient remaining in place. Subfreezing lows are expected area wide, with teens likely along and north of I-40/I-44.
230 AM CST Fri Feb 17 2023 Surface ridging is building in from the Plains. The parent trough behind yesterday's storm system is approaching and should pass overhead by mid morning today. Wind chills will dip below freezing which will probably feel bitingly cold after our recent warm snap.
Most observation sites were in the low to mid teens early this morning and I don't expect temps to change much through the morning hours. Sunny to partly cloudy skies should help temperatures warm into the low/mid 20s today, but a mid-level inversion tempers the warm up by preventing mixing above 2-3 kft.
(Today and tonight) Warmer temperatures under sunny skies expected today but still about 5 to 10 degrees below average.
958 PM MST Thu Feb 16 2023 A ridge of high pressure over the Great Basin region will dominate the weather pattern tonight with clear conditions and unseasonably cold temperatures. Expect another round of frigid temperatures tonight under the ridge of high pressure with high valley locations dropping well below zero overnight. The ridge will slowly flatten and push east tomorrow and tomorrow night as a weak storm system impacts the Pacific northwest region. Expect high temperatures tomorrow to be around 10 degrees warmer than today but still well below normal for this time of year.
1104 PM EST Thu Feb 16 2023 Scattered showers will occur along a cold front as it crosses east through the Ohio Valley this evening. Dry and significantly colder air will rush in behind it, keeping highs on Friday only about a handful of degrees warmer than the morning low.
A cold front can be seen moving east near the I-65 corridor, and cooler temperatures will move into the area through the overnight hours.
1240 AM EST Fri Feb 17 2023 (06Z TAFS) VFR expected through period with increasing clouds ahead of an approaching cold front later today.
