1107 AM MST Thu Feb 10 2022 Persistent northwest flow is expected continue in the near term as high pressure remains anchored over the West Coast while a deep trough lingers over the center of the nation. It seems the overturning will allow milder air aloft to mix down offsetting the influx of cooler air at the surface. Meanwhile, the overnight low tonight will trend just a bit warmer for much of the area. High pressure continues along the West Coast pushing the storm track to the east along the Front Range. The western Colorado and eastern Utah counties will see warm temperatures through the weekend with the ridge over the Western US. This deep trough pulls the Hudson Bay low east and north as it rotates through resulting in the ridge decaying under the shifting longwave pattern.
1106 AM CST Thu Feb 10 2022 (Today and tonight) Generally quiet weather with warmer than normal temperatures expected for the area today. An upper level trough will move southeast through the southern plains, dragging a weak cold front with it. Otherwise, we may see a few mid and upper level clouds associated with the trough as it moves through. Lows tonight should be a few degrees warmer, mostly in the mid and upper 30s with a few readings in the lower 40s.
Low clouds cover most of the lowlands Thursday morning and there is sunshine in the mountains. An upper level ridge will keep weather systems away from Western Washington into the weekend. The low level air mass should dry as light offshore flow develops through Friday and then peaks over the weekend.
1008 AM EST Thu Feb 10 2022 A weak cold front will swing through the region early today which will offer widely scattered rain and snow showers, mainly north of Interstate 70.
Cyclogenesis over the Great Lakes will keep the CWA in southwesterly surface flow, ahead of a cold front that will be moving southeast through the mid- Mississippi river valley tomorrow. Given the mixed layer will be maximized tomorrow, decided to go with the warmer CONSMOS guidance over the NBM or another blend of models. This gives mid to even upper 60s for much of the lower elevations across the CWA, and even low 60s into southwest VA and the valleys of Cherokee and Clay counties in western NC.
At the surface, high pressure has slowly been drifting southward throughout the day allowing winds to maintain a notable easterly component while gradually weakening. Despite this, the low levels have been and will continue to remain dry. The next in our series of fronts will pass through the region on Friday, but in contrast to earlier this week, this front will be quite a bit stronger and will open the door for cooler air to surge into the region.
Slight ridging in the upper levels will keep things quiet through Friday, with mostly clear skies and overnight lows ranging from the mid 30s to the mid 40s. Winds will shift out of the southwest and increase ahead of a cold front approaching the region. The cold front will enter into northern Oklahoma Friday morning and move through the region in the morning and through the afternoon. Ahead of the cold front, temperatures will warm up slightly compared to Thursday, with highs in the low 70s mainly in southern Oklahoma and northern Texas. Elsewhere the cold front will limit high temperatures in the 60s with the cooler airmass and more sporadic cloud cover.
1053 AM MST Thu Feb 10 2022 Overview: The High Plains will be situated on/near an 'inflection point' in the synoptic pattern -- in NW-NNW flow aloft -- between a pronounced upper level ridge along the Pacific coast and a deep/broad upper level trough over the central/eastern CONUS. as the MSLP/H85 height gradient re-orient/tighten in response to an intensifying low pressure system progressing southeastward from Saskatchewan into the Upper Midwest (northern Minnesota). manifesting as a northerly wind shift / effective cold frontal passage. Expect highs a good 10-15F cooler than today. with highs ranging from the lower to upper 40s.
1031 AM EST Thu Feb 10 2022 High pressure overhead today with dry weather and seasonable temperatures expected. Even though skies will remain mostly clear, and winds will predominantly be calm overnight tonight, temperatures are not expected to drop to near freezing again, but remain in the low 40s to upper 30s areawide.
The best locations to see accumulating snow will be across western Cherry county, Sheridan county and the Pine Ridge region where more elevated terrain may help to enhance precipitation potential.
A continued ridge of high pressure building in from the west will allow for dry and mostly clear conditions through the weekend. Patchy fog and low clouds are still expected in the lower Treasure Valley tonight and Friday night as the temperature inversion continues to build in the valleys.
926 PM EST Thu Feb 10 2022 High pressure will control our weather through Friday.
306 PM MST Thu Feb 10 2022 At the start of the short term period, current RAP analysis shows the CWA having a north-northwesterly flow aloft as the back part of a trough is over the CWA. Late Friday, models show the upper air flow turning more northwesterly as the trough starts to reorient itself. For Friday, forecast guidance shows the base of a reoriented upper air trough over the CWA yielding a west-northwesterly flow aloft. Closer to the surface, a cold front associated with a low pressure system over the Great Lakes moves begins to move through the CWA during the morning hours. Daytime highs for Friday look to range between the lower 40s and lower 50s with overnight lows in the middle teens to lower 20s.
A second round of light precip is possible with the first cold front that will push through later tonight. It'll feel 15 degrees cooler than that.
Light winds through Friday morning when the next cold front will bring a shift to north winds, increasing and potentially becoming gusty. At the surface, high pressure has slowly been drifting southward throughout the day allowing winds to maintain a notable easterly component while gradually weakening. Despite this, the low levels have been and will continue to remain dry. The next in our series of fronts will pass through the region on Friday, but in contrast to earlier this week, this front will be quite a bit stronger and will open the door for cooler air to surge into the region.
/NF/ Tonight through Friday: Temperatures tonight will be notably warmer with winds increasing and becoming southwesterly. Lows tonight fall into the lower 40s F, about 10 degrees warmer than this morning. Dry air and high pressure will be in control and temperatures will warm quickly into the lower 70s F for most. While southerly winds may help keep our dewpoints into the 30s F as opposed to the 20s F seen in previous days, the additional wind and warmer temperatures will serve to continue hazardous fire weather conditions.
The High Wind Warnings have verified well so far. Friday, the main wind threat shifts to the Nebraska panhandle after the passage of a cold front. Light precipitation will develop over the CWA with the passage of the cold front. Snow accumulations in the lower elevations will be light, while the higher terrain will likely pick up more than 2 inches.
Cirrus band will move out of the area this evening as a mid to upper level short wave trough moves through the Edwards Plateau to the Hill Country tonight. Weak low level warm air advection and a weak short wave trough moving through south Texas could lead to isolated showers along the coast of the southern Coastal Bend late Friday night.
712 PM EST Thu Feb 10 2022 A high pressure system will provide dry weather through Friday morning.
444 PM EST Thu Feb 10 2022 The area remains between a robust low pressure system over the Great Lakes and high pressure over the southeast United States, which will result in above normal temperatures on Friday.
For overnight and into Friday, we'll be watching a cold front dropping south across the region. Will continue to monitor potential into the evening and overnight hours, but it would seem any existing snow on the ground may be difficult to blow around after highs in the lower 40s over the Coteau region.
Mild conditions ongoing this afternoon with high temperatures topping out in the low 70s. A southwest wind is forecast to develop across the area on Friday ahead of a cold front approaching from the north.
The cold front and its associated pressure rises have yet to move through. But upstream observations in Canada are only showing peak gusts around 30 kts, and the low level jet max is forecast to remain displaced to the south. A cold front approaches from Canada this evening and crosses the state from north to south overnight. Along and behind the cold front, expect light precipitation to develop, possibly as a mix of rain and snow at first, transitioning to all snow by Friday morning. Friday's highs will be much cooler with lows ranging from around zero across the Turtle Mountains, to the upper 20s southwest.
549 PM CST Thu Feb 10 2022 High pressure continues over the area with mainly clear skies. A cold front will move into the state Friday.
244 PM MST Thu Feb 10 2022 North-northwesterly flow aloft with the longwave trough over the Midwest and the high in place over the West Coast has the storm track along the Front Range. Expect rime ice possible in the shallow moist layer upwind of peaks and ridges that are in the low clouds where temperatures are below freezing.
As the lower level trough swings through tomorrow there will be a few more clouds around.
Some patchy ground fog or frost wl be possible in cooler locations of northwest Volusia and northern Lake county. The extended area of high pressure will remain draped across north Florida, continuing the dry conditions and clear skies. Favorable open water conditions as broad high pressure extends from the north Gulf coast, across north Florida, and off the Carolina coast.
359 PM MST Thu Feb 10 2022 At the upper levels, active northwest flow is expected through most of the forecast period, with multiple waves expected to ride down the western CONUS ridge. With passage of the cold front, temps are expected to remain steady or even drop as we progress through Friday.
Beginnings of the cold front seems to be slowly marching southward now. May have missed one out of the High Wind Warning, but feel like the event is now nearly over, and most of the remaining severe gusts will remain in the warning.
914 PM EST Thu Feb 10 2022 The area remains between a robust low pressure system over the Great Lakes and high pressure over the southeast United States, which will result in above normal temperatures on Friday.
442 PM EST Thu Feb 10 2022 A cold front will exit to the east this evening.
641 PM EST Thu Feb 10 2022 The forecast will trend mostly dry through Thursday night before the next low pressure system arrives on Friday. Periods of rain are expected on Friday, with light snow possible Friday night behind a cold front.
Strong high pressure aloft situated along the West Coast will result in clear skies and well above normal temperatures at least through the weekend.
Warm air riding southwest winds in the lower levels will induce rain in our northern counties continuing at times as a series of cold fronts arrive. The first of two cold fronts arriving on Friday morning will provide a source of low-level convergence, allowing rain to continue. Friday will still be a mild day with highs ranging from the upper 40s to the low-60s from north to south. The second cold front will pass through the area Friday evening.
309 PM MST Thu Feb 10 2022 At the start of the short term period, current RAP analysis shows the CWA having a north-northwesterly flow aloft as the back part of a trough is over the CWA. Late Friday, models show the upper air flow turning more northwesterly as the trough starts to reorient itself. For Friday, forecast guidance shows the base of a reoriented upper air trough over the CWA yielding a west-northwesterly flow aloft. Closer to the surface, a cold front associated with a low pressure system over the Great Lakes moves begins to move through the CWA during the morning hours. Daytime highs for Friday look to range between the lower 40s and lower 50s with overnight lows in the middle teens to lower 20s.
Water vapor imagery highlights a trough axis pivoting through Mexico, downstream from a second cyclone surging southwest near the Baja.
800 PM MST Thu Feb 10 2022 02z surface analysis had cold front from the Big Horns into far southwest SD. Good recipe for highly sought after snows over the higher elevations into Friday. At the upper levels, active northwest flow is expected through most of the forecast period, with multiple waves expected to ride down the western CONUS ridge. With passage of the cold front, temps are expected to remain steady or even drop as we progress through Friday.
The winds aloft this evening will turn north and bring in cooler air, this will simply return us to temperatures about 5 degrees above normal and should allow for below freezing temperatures overnight.
Issued by National Weather Service Tucson AZ 223 PM MST Thu Feb 10 2022 Strong high pressure aloft situated along the West Coast will result in clear skies and well above normal temperatures at least through the weekend.
Well above normal temperatures, light winds and dry conditions under mostly clear skies will continue through the weekend under a strong ridge of high pressure.
Building high pressure and a local thermal trough will promote gusty northeast winds, clear skies and near record to record high temperatures into the weekend.
258 PM PST Thu Feb 10 2022 After another mild day across much of the Inland Northwest, a dry cold front tonight should knock temperatures back into the upper 30s and 40s for Friday.
446 PM MST Thu Feb 10 2022 North-northwesterly flow aloft with the longwave trough over the Midwest and the high in place over the West Coast has the storm track along the Front Range. Expect rime ice possible in the shallow moist layer upwind of peaks and ridges that are in the low clouds where temperatures are below freezing.
Moisture will increase slightly through the day on Saturday as a cold front approaches from the northwest, however no precip is expected through the day on Saturday. Lows on Friday night will be in the low to mid 40s inland to near 50 along the coast.
Expect to see a rapid expansion and lowering of the low stratus area that is present this evening across the upper Snake Plain. Expect these conditions to continue under influence of high pressure through the short term and into the weekend.
A cold front moves through the area later today, bringing a brief period of snow showers this evening and much colder weather for the weekend.
On Friday an H5 trough will begin to dig south from Canada into the Plains/Great Lakes. Behind the cold front, a shot of cold Canadian air will move over the region.
1012 PM EST Thu Feb 10 2022 High pressure will prevail across the region into Saturday.
At the surface, high pressure has slowly been drifting southward throughout the day allowing winds to maintain a notable easterly component while gradually weakening. Despite this, the low levels have been and will continue to remain dry. The next in our series of fronts will pass through the region on Friday, but in contrast to earlier this week, this front will be quite a bit stronger and will open the door for cooler air to surge into the region. /DWK A quick moving upper level system will dive into the forecast area Saturday morning in the wake of the aforementioned cold front. Model guidance continues to struggle with the amount of moisture that will be available with this system although ensembles continue to show that the southwest Texas Panhandle has the highest probability to see precipitation in our forecast area.
/issued 948 PM CST Thu Feb 10 2022/ High pressure has shifted SE as a cold front moves through the plains.
(Today and tonight) Stronger cold front expected to move into northwest Oklahoma around sunrise will move quickly southeast across the area today. Still expect to see mild conditions today before cooler/colder air moves into the area tonight. Colder air will filter south tonight as upper wave drops south through the high Plains into west Texas.
Temperatures warm above freezing after the snow moves through with the potential for more bursts of a rain/snow mix across central MN and western WI. If surface temperatures fall below freezing, areas could see a light glazing of ice. This is most likely across the northern part of the forecast area as temperatures fall behind a passing cold front early Friday morning.
Discussion: A low pressure system will be tracking across the Great Lakes today, with a trailing cold front crossing the OH Valley region. Tonight, the cold front moves SE across KY, and near our northern borders by 12Z.
Cold front will move through today with light precipitation chances.
948 PM CST Thu Feb 10 2022 High pressure has shifted SE as a cold front moves through the plains.
High pressure will continue to control South Floridas weather through Saturday as the high shift from the Southeastern United States into the Atlantic water.
Patchy MVFR/IFR in fog/low stratus is expected late tonight and Friday morning in the KBKE and KMYL areas and the Lower Treasure Valley (KEUL, KONO). A continued ridge of high pressure building in from the west will allow for dry and mostly clear conditions through the weekend. Patchy fog and low clouds are still expected in the lower Treasure Valley tonight and Friday night as the temperature inversion continues in the valleys.
348 AM EST Fri Feb 11 2022 High pressure will prevail across the region into Saturday.
A cold front will bring much cooler temperatures to the area for Saturday.
Another warm day on tap for the area as high pressure remains over the southeast. Tonight, we will begin to see clouds increase after Midnight in the northwest as the cold front will begin to approach the area from the northwest.
828 PM MST Thu Feb 10 2022 8 pm update: Temperatures have fallen enough in the higher elevations of the SW zones for rain to change to snow. Winds have diminished enough that the High Wind Warning was allowed to expire at 00z. Beginnings of the cold front seems to be slowly marching southward now. May have missed one out of the High Wind Warning, but feel like the event is now nearly over, and most of the remaining severe gusts will remain in the warning.
Expecting this area to expand in coverage through the overnight and likely infiltrate portions of the lower Snake and Magic Valley. Aside from this, expecting quiet weather to continue today and into the day Saturday as well as high pressure continues to dominate local weather. Temperatures will be around seasonal norms in the afternoon although continued a bit warmer in the mountain valleys than the Snake Plain.
Snow winding down this morning, warmer today. Strong isentropic lift in the warm advection pattern of a mid latitude cyclone near Lake Superior has resulted in a brief period of moderate to heavy snow over the cwa this morning. The Lake Superior low will drag a cold front through as it moves east to Ontario tonight.
High pressure will continue over the area with mainly clear skies overnight. Winds will become southwest and gusty Friday as a cold front enters the state. High pressure continues over the area with mainly clear skies. A cold front will move into the state Friday. A cold front will begin moving into the state tomorrow afternoon. The front will continue to push thru the state tomorrow night thru Saturday morning, which will bring considerably cooler air into the region. How much cooler? Highs on Saturday will be 20-25 degrees lower than Friday in most areas. A upper level trof will be swinging thru, and with the front there may be a bit of rain across the southern half of the state on Saturday.
The High Wind Warnings have verified well so far. Friday, the main wind threat shifts to the Nebraska panhandle after the passage of a cold front. Light precipitation will develop over the CWA with the passage of the cold front. Snow accumulations in the lower elevations will be light, while the higher terrain will likely pick up more than 2 inches. Saturday marks the start of a warming trend as a ridge of high pressure begins to build over the west.
317 AM EST Fri Feb 11 2022 Satellite imagery shows cirrus streaming across the southern two- thirds of the CWA this morning as an elongated piece of vorticity traverses the Southeast amid weak upper-level troughing. Broad upper-level troughing will encompass the eastern two-thirds of the CONUS on Saturday with a sprawling area of high pressure on its heels over the western CONUS. These features will push a cold front south and east across the Southeast through the day.
Temperatures ranging in the upper 40s to mid 50s, expected to fall into the lower/mid 40s by daybreak. By early Saturday morning, a cold frontal boundary is anticipated to be sliding southward through the local forecast area.
Following that, a weak back door cold front will begin to drop southward into northeastern portions of the area. Quiet weather will then return for the weekend, as ridging builds across the state, bringing a continuation of above normal temperatures and dry conditions.
1056 PM EST Thu Feb 10 2022 A broad and weak area of high pressure is sliding into the southeast U. This cluster has finally dwindled as we lose that convergence thanks to the incoming high pressure.
Valley locations near Fort Payne could drop into the lower 30s in spots, since winds may remain light longer there. This increase in wind occurs as a decaying pre- frontal trough axis currently located from south central Missouri into northeastern Texas approaches the area towards daybreak. This will setup quite a ridge/valley temperatures split as you wake up on Friday morning, with lows in the higher elevations only dropping into the upper 30s to lower 40s. Late Friday, an upper level trough digs down into the Central U. with a cold front along the leading edge. This northern stream trough attempts to phase with the southern stream creating a strong low pressure system off the east coast.
1023 PM EST Thu Feb 10 2022 High pressure makes a brief influence over PA before another Alberta Clipper tracks through southeastern Canada Friday into Saturday.
251 AM EST Fri Feb 11 2022 Precipitation chances return later today with crossing low pressure. Scattered light snow will linger Saturday but largely be finished by the afternoon with the exception of the ridges and north of I-80 where orographic lift and lake enhancement will keep light snow possible into Saturday night.
102 AM EST Fri Feb 11 2022 A high pressure system will provide dry weather through Friday morning. Chances for rain with another cold front Friday afternoon into Saturday, changing over to snow late Saturday. A high pressure system will provide dry weather tonight. An approaching cold front will then push moisture into the region on Friday. The short term period begins with a cold front approaching and moving through the region Friday night into Saturday.
1236 AM EST Fri Feb 11 2022 High pressure will control our weather through Friday.
1239 AM EST Fri Feb 11 2022 High pressure will prevail across the region into Saturday.
1018 PM MST Thu Feb 10 2022 02z surface analysis had cold front from the Big Horns into far southwest SD. Good recipe for highly sought after snows over the higher elevations into Friday. At the upper levels, active northwest flow is expected through most of the forecast period, with multiple waves expected to ride down the western CONUS ridge. With passage of the cold front, temps are expected to remain steady or even drop as we progress through Friday.
Slight ridging in the upper levels will keep things quiet through Friday, with mostly clear skies and overnight lows ranging from the mid 30s to the mid 40s. Winds will shift out of the southwest and increase ahead of a cold front approaching the region. The cold front will enter into northern Oklahoma Friday morning and move through the region in the morning and through the afternoon.
