Surface temperatures will be near or above freezing through this evening while the majority of the precipitation is falling but temperatures are expected to drop into the teens and 20s which will likely re-freeze any moisture remaining on roadways tonight.
Observed gusts in the Colorado River Valley, where winds are strongest, have generally been in the 30s with a couple in the low 40s.
Upper level trough currently over Colorado will shift southeast of the area this morning yet. Highs are expected to range from the lower 30s along the foothills to the mid 20s over the eastern plains.
Temperatures remain in the lower 70s in the Bluegrass Region, where winds have been gusting to 50-60 mph over the past hour. A broad area of clearing has now developed along the cold front, and behind the boundary with clear skies noted back to the I-65 corridor. The High Wind Warning remains in effect through 4 PM EST for wind gusts up to 60-65 mph. Afternoon highs should range from the lower 40s in southern IN to the lower 50s in south-central KY.
101 PM MST Thu Feb 9 2023 Latest upper air analysis shows a deepening trough over the Desert Southwest, with a ridge moving onto the West Coast. The cold front continued diving south with the trough, now well into New Mexico and the Texas Panhandle. The window for any snow to occur will end as the 500mb trough axis moves through the forecast area this evening. Highs will be warmer, with a clear sky, as the upper level ridge moves overhead. Friday night southwest winds will be a breezy, allowing lows to be a few degrees warmer than tonight.
1029 AM MST Thu Feb 9 2023 Most recent upper air models show upper ridge over the west coast with toughing on the lee side of the Rockies. Current surface analysis depicts low pressure over northern Minnesota, and a cold front stretching east to west through southern North Dakota. The higher snowfall amounts are expected in the northern Black Hills, where upslope enhancement will aid in higher snowfall rates. Later today and into the weekend the upper ridge slides over the Rockies and the trough shifts east of the northern plains, with 850 temps rebounding to around 5C Friday.
1025 AM CST Thu Feb 9 2023 Surface analysis late this morning places a cold front from Middle Tennessee south through Western Alabama and into Southern Mississippi.
125 PM MST Thu Feb 9 2023 High pressure is in control across eastern Idaho as is quite evident by the widespread sunny skies in place. That being said, temperatures in the positive to negative single digits are likely in these areas overnight while the rest of the Snake Plain and Magic Valley will be a touch warmer but still generally in the teens. Still expecting mainly sunny skies to start the day Friday before cloud cover gradually increases a bit as the aforementioned area of high pressure gives way to U/L trough over the PacNW.
(Tonight) In the dry slot, southwest flow persists behind the cold front today.
As this low advects out of the state, the mid level frontogenesis and axis of WAA will move with it.
Despite the abundant insolation weâll receive, the highs will only warm into the 40s as a colder base airmass lingers.
Mostly clear skies will prevail today as an upper level ridge moves overhead. East to southeast winds will increase through the day as a trough of low pressure approaches the West Coast.
----- Cold front dropping dropping south through the forecast area, but with low clouds behind it temps actually rise behind its passage. Cold advection is not great behind the front (in fact warmer at the sfc) but 925-850 mb cold advection is moderate at best. Been watching for any freezing drizzle and reports via social media just haven't confirmed any.
At the surface, a cold front will move south across the area late this afternoon and early evening. The cold front is currently located just south of the I-20 corridor, with current temperatures in the upper 60s to lower 70s ahead of the front.
1045 AM CST Thu Feb 9 2023 (Rest of Today) The cold front was moving east of the I-65 corridor at this hour, just passing through here at the WFO a few moments ago.
The aforementioned three counties expire at 11 PM, mainly for wind that develops on the back side of the low and moves over the lake. The pcpn on the southern side just ahead of the cold front is all rain and that will move into the cwa this afternoon.
306 PM EST Thu Feb 9 2023 High pressure will continue to ridge across the area this evening as a cold front settles into northern FL and stalls.
A dry cold front will push through the state today resulting in a return of colder temperatures and gusty northeast winds.
1159 AM CST Thu Feb 9 2023 (Today and tonight) Patchy fog and areas of freezing fog have been observed this morning along an area from Chickasha to Paul's Valley to Ardmore. Freezing Fog and Dense Fog Advisories will be issued momentarily. This reinforcing cold front pushes into northwest Oklahoma this morning, reaching PNC- OKC-LAW by mid-morning and exiting by late afternoon or evening.
917 AM MST Thu Feb 9 2023 Upper level ridging will provide a dry end to the week. To start the period, upper level ridging is building across the western CONUS, slowly shifting eastward. An approaching upper trough from the northeastern Pacific Ocean will help usher the upper ridge eastward Friday, turning flow in the mid levels more westerly. Strong westerly winds will be present aloft, but without appreciable ridgetop stability, these strong winds are largely expected to remain decoupled from the surface. The aforementioned upper level trough will split, sending most support for precipitation toward the Southwest US.
Temperatures range from 80 to 84 degrees, with dewpoints in the lower 70s. High pressure centered near Bermuda will maintain fresh east to southeast breezes tonight. Breezes will diminish somewhat and veer to the southeast Friday and Friday night as the high pressure system recedes to the east.
241 PM MST Thu Feb 9 2023 Temperatures look to rebound across the CWA on Friday as upper ridging extends across the Rockies.
530 PM CST Thu Feb 9 2023 Clouds will decrease tonight as an upper level low departs the Mid-South.
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.
(This evening through Friday Night) A reinforcing cold front, currently making its way into north Tx, will be pushing through the region overnight and off the coast in the 4-6am timeframe. Breezy and cooler conditions are expected on Friday.
This cloud deck could lead to temps remaining a few degrees warmer than expected in some areas, otherwise temps will fall into the 30s to low 40s by tomorrow morning. Cooler day expected tomorrow with highs near-normal in the 50s by the afternoon. The cold front has swept through our area, and behind it, dry and clearing skies prevail. Low temperatures do cool several degrees compared to last night, but are still forecast to remain a few degrees above freezing.
627 PM CST Thu Feb 9 2023 (This evening through Friday Night) A reinforcing cold front, currently making its way into north Tx, will be pushing through the region overnight and off the coast in the 4-6am timeframe. Breezy and cooler conditions are expected on Friday.
519 PM EST Thu Feb 9 2023 The latest upper level map features troughing aligned from Ontario down through the Desert Southwest, with deeper southwest flow for most east of the Mississippi River. At the surface, occluding low pressure is departing east northeast across the Great Lakes, with a cold front positioned south southwest through the Ohio and Tennessee valleys and Deep South. Strong wind gusts and record breaking temperatures in mostly the low and mid 70s have been the story across eastern Kentucky today. The models agree on the upper trough to our west to move through the Mississippi Valley by the end of the period.
At the surface, a cold front has pushed out ahead of the approaching low, and recently sagged south through the I-20 corridor. Strong surface pressure rises will take place upstream as the upper low moves farther south and east, which will increase the pressure gradient locally. The upper low will continue to deepen as the system moves southeast over North and Central Texas Friday and Friday night. Moisture was largely scoured by the previous upper low, but the Friday system should be strong enough to generate light precipitation across the northern half of the forecast area. Thicknesses aloft are supportive of snow, but the limiting factor in this case will be surface temperatures, which should be above freezing area-wide.
Cooler air will filter into northern IL on these northerly winds, and this could allow for some of the lingering moisture falling in the deformation band to mix with some wet snow flakes over northeastern IL early this evening before the precipitation comes to an end.
A trailing cold front pushes through tonight bringing gusty winds to the area.
254 PM MST Thu Feb 9 2023 H5 ridging drifting across the Rockies will keep Wyoming stable and mostly sunny into the upcoming weekend.
403 PM MST Thu Feb 9 2023 Water vapor imagery shows a positively tilted trough across the central CONUS, with the base over NM/TX. Strong upper ridging is building across much of the western CONUS, and quickly moving into the northern Plains. Warmer air will advect in overnight.
Cooler, but still above normal temperatures are expected Friday with a slight chance of precipitation during the afternoon. Latest progs show the boundary east of the ridges by midnight.
512 PM CST Thu Feb 9 2023 (Tonight) Cold front currently moving into far northeast Oklahoma this afternoon as positively tilted upper trough approaches from the northwest. (Tonight through Thursday) The main upper low, currently over southern NM, will shift east across Texas during the day Friday. Upper low tracks a little too far south across the ARKLATX region before becoming better organized, thus limiting a more significant winter weather threat. Still expect some light snow accumulations in the higher terrain over SE OK and maybe far NW AR before system moves well southeast of the region Friday evening. Warming trend expected over the weekend as weak upper ridge develops.
High pressure covers Nevada through Friday with cold conditions continuing.
236 PM MST Thu Feb 9 2023 Water vapor imagery shows a positively tilted trough across the central CONUS, with the base over NM/TX. Strong upper ridging is building across much of the western CONUS, and quickly moving into the northern Plains. Warmer air will advect in overnight.
945 PM EST Thu Feb 9 2023 Forecast remains on track as today's windy low pressure moves off into Canada, allowing winds in the Ohio Valley to relax. Winds are already calm in far western Kentucky as high pressure builds in from the west. Strong low pressure is continuing to move to the northeast, from Michigan into Ontario. Temperatures remain in the lower 70s in the Bluegrass Region, where winds have been gusting to 50-60 mph over the past hour. A broad area of clearing has now developed along the cold front, and behind the boundary with clear skies noted back to the I-65 corridor. The High Wind Warning remains in effect through 4 PM EST for wind gusts up to 60-65 mph. Afternoon highs should range from the lower 40s in southern IN to the lower 50s in south-central KY.
518 PM CST Thu Feb 9 2023 (Tonight) In the dry slot, southwest flow persists behind the cold front today.
326 PM CST Thu Feb 9 2023 Currently, the low pressure system that brought rain and snow to the region yesterday and last night continues to pull northeast through the mid Mississippi Valley. Right on the heels of this system is another trough, whose axis will move across the area this evening through early tomorrow morning. As the trough departs the region, ridging will quickly follow, making for a decent weekend across the area with high temperatures back into the 50s.
600 PM CST Thu Feb 9 2023 Currently, the low pressure system that brought rain and snow to the region yesterday and last night continues to pull northeast through the mid Mississippi Valley. Right on the heels of this system is another trough, whose axis will move across the area this evening through early tomorrow morning. As the trough departs the region, ridging will quickly follow, making for a decent weekend across the area with high temperatures back into the 50s.
Cooler, but still above normal temperatures are expected Friday with a slight chance of precipitation during the afternoon. Well above normal temperatures in place as a warm front continues to lift north across the region.
339 PM CST Thu Feb 9 2023 Clouds will decrease tonight as an upper level low departs the Mid-South.
300 PM MST Thu Feb 9 2023 Relatively warm and dry high pressure will be present over the Northern Rockies through midday Friday.
227 PM MST Thu Feb 9 2023 Upper trough axis will drift off to the south and east through tonight, with ridging shifting back into the forecast area on Friday. Much drier air associated with approaching ridge will also arrive tonight. An upper level ridge will build over the area on Sat as a strong storm system is over California. This will lead to a dry day with warmer temps. Overall, this will lead to another dry day with cooler temps, over nern CO, as readings along the I-25 Corridor drop back to seasonal levels. Looking ahead to Tue and Wed, a strong upper level trough will develop over the wrn US and eventually develop an intense closed upper level low over the Great Basin by late Tue.
251 PM MST Thu Feb 9 2023 Satellite imagery shows an amplified ridge axis over WA/OR/ID and dry northerly flow over our region, with building heights from the west. As the upper ridge shifts east, mid level winds will back to the west, as lee side pressure gradients continue to tighten. Expect winds to begin to decrease by midday as deepening trof to our west supports slackening pressure gradients. Although there will be gradually falling heights Friday and Friday night, we will remain dry as the Pacific coast trof splits well upstream, with a deep low forming over CA Friday night.
Overnight lows will only fall into the lower to mid 60s. Then, afternoon temperatures on Friday will feel more summer-like ranging from the lower 80s along the Nature Coast into the upper 80s for SWFL and parts of interior FL. High pressure will continue to ridge across the area this evening as a cold front settles into northern FL and stalls.
328 PM MST Thu Feb 9 2023 H5 ridging drifting across the Rockies will keep Wyoming stable and mostly sunny into the upcoming weekend.
728 PM EST Thu Feb 9 2023 Strong low pressure is continuing to move to the northeast, from Michigan into Ontario. Temperatures remain in the lower 70s in the Bluegrass Region, where winds have been gusting to 50-60 mph over the past hour. A broad area of clearing has now developed along the cold front, and behind the boundary with clear skies noted back to the I-65 corridor. The High Wind Warning remains in effect through 4 PM EST for wind gusts up to 60-65 mph. Afternoon highs should range from the lower 40s in southern IN to the lower 50s in south-central KY.
Cooler air will continue to move in with low temperatures in the 30s.
335 PM MST Thu Feb 9 2023 Latest upper air analysis shows a deepening trough over the Desert Southwest, with a ridge moving onto the West Coast. The cold front continued diving south with the trough, now well into New Mexico and the Texas Panhandle. The window for any snow to occur will end as the 500mb trough axis moves through the forecast area this evening. Highs will be warmer, with a clear sky, as the upper level ridge moves overhead. Friday night southwest winds will be a breezy, allowing lows to be a few degrees warmer than tonight. Latest ECMWF/GFS showing amplified upper ridge traversing the central Plains over the 24 hour period to start off the upcoming weekend.
1100 PM CST Thu Feb 9 2023 (Tonight) Cold front is now draped across the southeastern counties tonight, with a band of post-frontal showers moving from southwest to northeast, from Dallas county to Cleburne county. high temperatures will be in the low 60s to low 70s. northerly cooler air advecting into the state will start to affect temperatures. with lows in the lower 40s to lower 50s.
215 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.
The polar cold front now crossing the MS River will move across srn WI during the early morning hours. As this low advects out of the state, the mid level frontogenesis and axis of WAA will move with it.
(Tonight) Cold front is now draped across the southeastern counties tonight, with a band of post-frontal showers moving from southwest to northeast, from Dallas county to Cleburne county. high temperatures will be in the low 60s to low 70s. northerly cooler air advecting into the state will start to affect temperatures. with lows in the lower 40s to lower 50s.
Cooler air arrives for the weekend, with another low pressure center just to the east of the area. With the exit of the cold front to our east, the winds have dropped in intensity and will change direction throughout the day. Most of the cloud coverage should lift and exit the lowlands by the late evening, but will linger across the mountains into the overnight. The overnight lows will be able to drop down to just below seasonable for some cooler weather than what we have been experiencing lately.
320 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.
1059 PM CST Thu Feb 9 2023 (Tonight) As high pressure filters in from the West, dry conditions are expected to continue overnight throughout the TN Valley.
1020 PM MST Thu Feb 9 2023 Water vapor imagery shows a positively tilted trough across the central CONUS, with the base over NM/TX. Strong upper ridging is building across much of the western CONUS, and quickly moving into the northern Plains. Warmer air will advect in overnight.
/issued 125 PM MST Thu Feb 9 2023/ High pressure is in control across eastern Idaho as is quite evident by the widespread sunny skies in place. That being said, temperatures in the positive to negative single digits are likely in these areas overnight while the rest of the Snake Plain and Magic Valley will be a touch warmer but still generally in the teens. Still expecting mainly sunny skies to start the day Friday before cloud cover gradually increases a bit as the aforementioned area of high pressure gives way to U/L trough over the PacNW.
Temperatures solidly above freezing will preclude any snow accumulation. The thinking is that even if clearing is a bit quicker, the air and pavement temps are probably far enough freezing now to limit or preclude the risk of black ice development overnight. Cooler air will filter into northern IL on these northerly winds, and this could allow for some of the lingering moisture falling in the deformation band to mix with some wet snow flakes over northeastern IL early this evening before the precipitation comes to an end.
1129 PM CST Thu Feb 9 2023 Currently, the low pressure system that brought rain and snow to the region yesterday and last night continues to pull northeast through the mid Mississippi Valley. Right on the heels of this system is another trough, whose axis will move across the area this evening through early tomorrow morning. As the trough departs the region, ridging will quickly follow, making for a decent weekend across the area with high temperatures back into the 50s.
1025 PM CST Thu Feb 9 2023 (This afternoon through Friday night) Upper trough over NM today swinging into W TX this afternoon and tonight. On Friday this trough will slowly push east as ridge becomes centered over the 4 Corners region and builds into the area during the evening. A cold front moving through the CWA today will result in cooler temperatures tonight.
828 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.
356 AM EST Fri Feb 10 2023 High pressure will build into the region over the next couple of days.
Temperatures were in the lower 40s in most locations. Some clearing had worked into far western KY and there temps had dropped into the lower 30s. Temperatures may fall another couple of degrees prior to sunrise, with overnight lows likely in the upper 30s to the lower 40s. Across southern Indiana, highs in the lower-mid 40s are expected. ===================================== Tonight 700 PM to 700 AM EST Impacts: None Confidence: Medium-High ===================================== Upper trough over the southern Plains will continue to deepen and close off to our southwest. At the surface, high pressure will continue to build into the region tonight.
Forecast remains on track as today's windy low pressure moves off into Canada, allowing winds in the Ohio Valley to relax. Winds are already calm in far western Kentucky as high pressure builds in from the west. Strong low pressure is continuing to move to the northeast, from Michigan into Ontario. Temperatures remain in the lower 70s in the Bluegrass Region, where winds have been gusting to 50-60 mph over the past hour. A broad area of clearing has now developed along the cold front, and behind the boundary with clear skies noted back to the I-65 corridor. The High Wind Warning remains in effect through 4 PM EST for wind gusts up to 60-65 mph. Afternoon highs should range from the lower 40s in southern IN to the lower 50s in south-central KY.
(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.
(Tonight) As high pressure filters in from the West, dry conditions are expected to continue overnight throughout the TN Valley.
942 PM MST Thu Feb 9 2023 H5 ridging drifting across the Rockies will keep Wyoming stable and mostly sunny into the upcoming weekend.
352 AM EST Fri Feb 10 2023 A cold front will cross over the Mid Atlantic today but stall along the East Coast tonight.
111 AM EST Fri Feb 10 2023 A cold front will stall just south of the area Friday night.
208 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.
128 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.
