1106 PM CST Sun Jan 30 2022 As expected, today is running several degrees cooler than yesterday as a result of reduced mixing, a slightly cooler airmass aloft, and scattered high clouds moving through the area. On Monday, west to southwesterly winds at the low levels will strengthen as a trough approaches the area from the northwest. A cold front then moves through the area Monday night, ushering in a colder on Tuesday (highs near normal in the 30s and low 40s).
We should see the warmest temperatures of the week for this afternoon as skies will be mostly sunny and winds will pick up out of the southwest with a lee side trough in eastern Colorado. Highs today will be in the lower to mid 60s with the exception of the continued snow pack areas in Lane, Scott, and Finney counties where highs will be in the 50s. Tuesday a long wave trough will be organizing in the four corners region and a cold front will continue to move into southeast Kansas to central Oklahoma.
1014 PM PST Sun Jan 30 2022 A vigorous cold front will sweep across the Inland Northwest tonight bringing snow to the mountains, a wintry mix to the valleys and gusty winds.
Early Tuesday Cold Front Sets Stage for Storm Track.
A cold front will impact the forecast area tonight, producing snowfall. A vigorous upper level trough will move through the area late tonight and early Monday, bringing snow and a cold front. The snow will be mainly confined to the northern mountains, while the cold front will clear out the low level inversion that has been with us for quite a while.
Mostly clear skies tonight, with nearly calm winds in the valleys, and a light SE breeze at the ridge tops. Low temps will be in the low to mid 20s, with some upper 20s mainly along the ridges. Partly cloudy skies expected with afternoon high temps soaring into the lower to middle 50s.
137 AM EST Mon Jan 31 2022 High pressure along with relatively dry air will remain in control of the region through the middle of the week with a gradual warming trend.
900 PM PST Sun Jan 30 2022 A weak ridge aloft will keep the weather fair and mild through Monday, but nights will be chilly. On Tuesday, a developing trough will spin up a coastal eddy, deepening the marine layer, and spreading patchy low clouds and cooling well inland through Tuesday night. For the remainder of the week, a strong East Pacific ridge will funnel disturbances south over the Rockies.
Lee troughing across eastern Colorado will bring southwesterly winds to western Kansas through tomorrow. As for temperatures, lows tonight will fall to around 20 degrees with highs tomorrow in the low 60s with the exception of where snow still exists where low 50s will be found. An upper level trough of low pressure will dig into the western United States Tuesday and help push a strong cold front through the area early in the day Tuesday.
Tonight, surface winds become more southerly and warm air advection increases over the region as an upper-level ridge builds in from the west for tomorrow. However, the colder air returns by late afternoon Tuesday with the passage of a cold front and surface winds become more northwesterly. A southwest to northeast oriented jet increases aloft as a positively tilted trough digs through the western coastal states into the Baja/California region.
Today/Monday: With weak CAA, cooler temperatures have commenced across the area, albeit still above normal across non-snow covered areas, with readings in the 40s. Southerly winds return this evening, and temperatures overnight will be a few degrees warmer than last night. Upper ridge builds back across the central CONUS on Monday ahead of our next period of disturbed weather. Scattered showers are expected to develop by Tuesday morning along and ahead of a cold front.
251 AM CST Mon Jan 31 2022 Dry and warmer weather will be on tap across central Illinois today as afternoon high temperatures reach the upper 30s and lower 40s.
Lows tomorrow morning will be in the mid-20s to mid-30s, and highs tomorrow afternoon will be in the lower 50s to mid-60s. Upper low currently over the desert southwest should move southeast into the northern Gulf of Mexico by early Tuesday. This low will fill and weaken as it moves into the Gulf and then eastward onto the FL peninsula. A second low and associated longwave trough will begin to dig in the southwest by midweek, with the upper flow turning more southwest.
335 AM EST Mon Jan 31 2022 Cold temperatures are expected Today and Tuesday with Canadian high pressure over the region before warmer air arrives at least briefly, midweek.

133 AM EST Mon Jan 31 2022 Dry high pressure Monday and Tuesday.
Again, believe the jet streak will initiate the snowfall and then transition as a deep trough approaches from the northwest. Some light snow will begin over the San Juans Tuesday afternoon and as the upper level trough continues to approach, snow will start to overspread to the central mountains. As previously mentioned, southwesterly flow ahead of the trough will provide favorable orographic lift and will bring the heaviest snow to the Wolf Creek Pass area through this whole event. The Pagosa Springs area will also see decent snowfall under this southwest flow with 4 to 8 inches possible but am thinking this might be a bit on the low side. The Durango area will also get in on some of the action with 3 to 5 inches possible but, like Pagosa, this might be on the low side.
218 AM MST Mon Jan 31 2022 Current surface map places deepening low across southern Alberta with lee trof extending into Wyoming. Upper trof digging across the northern Rockies will move through the Dakotas late today. Initial cold front crosses western South Dakota this afternoon, with arctic front dropping into the area overnight. Main issue today will be the wind, which combined with the low relative humidity, will result in critical fire weather conditions. Winds pick up early this afternoon with pressure rise bubble behind initial cold front. so have upgraded the High Wind Watch to a Warning.

A dry cold front will bring colder temperatures and increased winds to begin the month of February. Benign and dry weather will persist with a blocking ridge deflecting the storm track away from the Sierra and western Nevada through at least the first half of the month. A weakening cold front will move into the region through the morning hours, trailing a high latitude storm system over southern Canada and the northern Rockies. Other than an increase in winds along the ridges (gusts 50-60 mph) continuing into the morning hours, nothing noteworthy as far as sensible weather goes as all of the moisture stays northward into Oregon and Idaho. Moving along into Tuesday, a trough will dig down on the eastern side of a deep, vertically stacked ridge of high pressure. This trough will finally drive some colder air into the region.
501 AM EST Mon Jan 31 2022 Northwesterly flow aloft will slowly transition to a more zonal flow this evening ahead of a weak upper level ridge that develops overhead tomorrow morning. High temperatures will reach the low 50s to upper 60s (possibly the low 70s across our southern CWA tomorrow afternoon) with lows dropping in the 30s and 40s.
/Issued 501 AM EST Mon Jan 31 2022/ Northwesterly flow aloft will slowly transition to a more zonal flow this evening ahead of a weak upper level ridge that develops overhead tomorrow morning. High temperatures will reach the low 50s to upper 60s (possibly the low 70s across our southern CWA tomorrow afternoon) with lows dropping in the 30s and 40s.
Not expecting any precipitation, but a cold front will usher in gusty winds and cooler temperatures that linger into the weekend.
Nice and quiet at forecast time across the mid-state, but it's definitely warmer than the last several mornings.
541 AM CST Mon Jan 31 2022 Dry and warmer weather will be on tap across central Illinois today as afternoon high temperatures reach the upper 30s and lower 40s.
This upper level low will move across Texas, bringing lift and a weak return of low level moisture during much of today. For tonight, the weather looks quiet and dry as the upper level low will be east of our area.
306 AM CST Mon Jan 31 2022 An upper level low centered over the southeastern corner of New Mexico at 07Z will move to the southeast through the day today, reaching a position over the lower Trans-Pecos at 18Z and between Del Rio and San Antonio at 00Z. Clearing skies, upper level short wave ridging, modest southwest to west surface winds, and the associated warming that will come from these will result in a warm afternoon with highs expected to be mostly in the upper 60s to lower 70s. Said cold front will likely just be entering the northwestern corner of the forecast area at the end of the overnight period.
536 AM CST Mon Jan 31 2022 Today: As upper level ridging shifts over the area today expect pleasant late January weather. Southerly winds will draw in much warmer air ahead of an approaching mid week system. Kansas city and areas to the south may even reach the low 60s.
Over the course of the late morning into the early afternoon southerly winds will have expanded westward, with warm air advection and deeper mixing of warmer low- levels/lower moisture driving warm temperatures and dryness this afternoon.
An upper low over Southeast New Mexico will continue to progress eastward generating possible precip on it's backside as it strengths. Zonal flow is expected to return to the area by Tuesday ahead of a strong cold front. This could impact the high temp forecast for Tuesday especially if the front speeds up.
630 AM EST Mon Jan 31 2022 Dry and warmer weather will be interrupted by a return of periodic precipitation for the mid to late week period. A mid-level ridge axis will approach tonight and crosses on Tuesday. This will begin to set up deeper southwest flow that will persist into the midweek period, in response to a deepening trough over the Rockies.
Sounding profiles signify a warm layer at around 800mb to 900mb, which could allow a brief period of freezing rain or drizzle as precipitation begins.
929 AM EST Mon Jan 31 2022 Dry high pressure Monday and Tuesday.
501 AM CST Mon Jan 31 2022 Today will be our last warm day before the cold front smashes through tonight. Tuesday will be the transition day with cold air advection throughout the day behind a strong cold frontal passage tonight.
A warm front will lift northward across the Midsouth today shifting winds from the south and ushering in higher moisture levels.
As ridging builds in this afternoon and tomorrow, temperatures are expected to warm back up near normal.
High pressure centered over central Florida will track eastward and build into the Western Atlantic today into tonight, starting a long period of onshore flow and beginning a warming trend lasting through the late week. One more chilly night is in store, with lows in the mid to lower 40s, and upper 30s possible in normally cooler inland spots. Light and variable winds as high pressure center transits central Florida. Boating conditions becoming favorable this afternoon as high pressure builds across the waters.
335 AM CST Mon Jan 31 2022 Today: As upper level ridging shifts over the area today expect pleasant late January weather. Southerly winds will draw in much warmer air ahead of an approaching mid week system. Kansas city and areas to the south may even reach the low 60s.
/Today Through Tuesday/ Upper-level ridge to shift east today allowing for southwest flow aloft to continue to bring increased moisture and cloud-cover to the region. Southerly winds to increase to around 10 mph across the ArkLaTex as the pressure gradient tightens between departing high pressure to the east and a cold front approaching from the west. Precipitation to become more widespread across the ArkLaTex on Tuesday as a cold front begins to ease southeast into north- central Texas, central Oklahoma and northwest Arkansas while at the same time a low to mid-level disturbance swings east across east Texas into the ArkLaTex. Afternoon high temperatures on Tuesday to climb into the low to mid 60s.
Much cooler across northern and central NV tonight, and through the middle of the week. Tonight into Tuesday reinforcing trough energy digs south through the inter-mountain west, with a cold continental air mass dropping through northern and into central NV.
Showers should taper off again Tue night as high pressure begins to build aloft and low level flow turns more northerly. Temperatures will trend slightly cooler than normal as we slide into February.
Today will also feature a good deal of wind as the low level wind field amplifies ahead of an approaching cold front. Behind the front much colder air will pour into the area with highs on Tuesday generally in the low to mid 30s, which will be about 30 degrees colder than readings today. Expect northern stream and southern stream energy will phase into a progressive deep trof over the western US.
419 AM CST Mon Jan 31 2022 Today will be our last warm day before the cold front smashes through tonight. Tuesday will be the transition day with cold air advection throughout the day behind a strong cold frontal passage tonight.
High pressure building off the coast will lead to gusty northerly winds across much of the region over the next few days. Afternoon high temperatures will likely be a little cooler than we have seen in a few days with highs only in the 50s in most areas. Temperatures along the coast will hover around the low 50s and with breezy northerly winds will likely feel more like 45. Winds on the coast are expected to be around 10 to 20 mph with a few gusts close to 30 mph on the exposed ridges this afternoon but will increase and peak on Tuesday with highest gusts near 40 mph across elevated terrain and localized areas.
A mainly dry cold front will cross the region today into early Tuesday.
/issued 306 AM CST Mon Jan 31 2022/ An upper level low centered over the southeastern corner of New Mexico at 07Z will move to the southeast through the day today, reaching a position over the lower Trans-Pecos at 18Z and between Del Rio and San Antonio at 00Z. Clearing skies, upper level short wave ridging, modest southwest to west surface winds, and the associated warming that will come from these will result in a warm afternoon with highs expected to be mostly in the upper 60s to lower 70s. Said cold front will likely just be entering the northwestern corner of the forecast area at the end of the overnight period.
554 AM EST Mon Jan 31 2022 Dry high pressure Monday and Tuesday.
Main impact today will be the passage of a Pacific cold front and the scouring out of strong inversions in low elevations. After high temperatures around freezing today will see about a 10 degree drop Tuesday behind the front.
Warm front pushing across eastern Montana this morning with some radar echoes in the vicinity of the front. As the cold front drops south this afternoon another round of precipitation is possible. The first round of precipitation will be mostly rain, although some colder temperatures in the northeast could result in freezing rain or snow.
Upper level ridging pushes into the Deep South, contributing to a warming trend relative to this past weekend. Issued at 448 CST Mon Jan 31 2022 By tonight, models continue to show an upper low moving east into eastern Texas. During the day on Tuesday guidance continues to show this upper low weakening as in moves toward the central Gulf of Mexico. The inverted trough axis models were depicting extending northward from the disturbance looks a bit weaker and not as far north in latest model runs. Newest guidance also seems to be more stationary with a fairly amplified longwave trough axis extending southwest from central Canada. This slower progression of the longwave trough axis should help to provide for a warmer day on Tuesday with highs reaching the 60 to 65 degree range in many locations.
Afternoon highs will be pleasantly in the mid to upper 60s, while high pressure centered over central Florida will keep conditions dry, winds light, and skies sunny. High pressure over Florida will depart eastward and build into the western Atlantic. Lows will be in the lower 40s to around 40, but could drop to just below 40 before daybreak. Elsewhere, lows will be in the low to mid 40s, but normally cold areas may briefly drop into the upper 30s as well. Onshore flow will increase through the day, bringing warmer and slightly more moist air to east central Florida. Afternoon highs will be seasonable in the lower 70s, with some afternoon clouds and gentle winds. Center of high pressure over Florida will transit the northern waters through the night, then build into the Western Atlantic through the week.
Made a quick update to the forecast late this morning to better capture an area of light snow showers and flurries associated with the cold front pushing into northern Utah. Radar shows light to modest returns, and webcams show anything from a skiff of snow by the side of the road (vicinity of I-15 at the UT/ID border) to snow falling in the distance over the higher terrain (Cache Valley north of Logan) to snow reaching the ground (Logan Canyon Summit). A mainly dry cold front will cross the region today into early Tuesday.
Otherwise today will be slightly warmer than yesterday with high temperatures near 70 expected area-wide.
331 PM EST Mon Jan 31 2022 Southerly winds on the backside of retreating high pressure will bring milder temperatures overnight and Tuesday.
A cold front passed through the area today which brought some light snow and breezy conditions to parts of the region today. Clouds should increase tonight as a second weak cold front will arrive for Tuesday. This will bring light snow mainly for the high country with accumulations expected to remain under an inch.
At the surface, ridging (extending from high pressure over Quebec) is departing to our east this afternoon.
High pressure bring dry and seasonable weather with a mostly clear sky. Discussion: High pressure shifts east tonight, but winds remain calm with a mostly clear sky. As low-level ridging strengthens across the East Coast tonight and Tuesday, southerly boundary layer winds increase and result in warming temperatures and increased moisture.
Forecast remains on track this afternoon as an upper level ridge moves across the Deep South. At the surface, a high pressure continues to move east across the Gulf resulting in a west-southwest surface flow throughout the day. Winds also remains light and variable today as the high pressure influences the area. Temperatures will also be warm this afternoon as those southerly winds advect warmer air off of the Gulf. Much of the area is currently sitting in the lower to mid 60, with a few areas potentially reaching the upper 60s later this afternoon.
234 PM EST Mon Jan 31 2022 High pressure along with relatively dry air will remain in control of the region through Tuesday followed by a gradual warming trend. Unsettled weather associated with an approaching cold front is expected late in the week.
The region will be in an area of relatively light flow for the next 24 hours with surface ridging retreating east of the area and a weak area of low pressure to the west.
There remains good agreement in a stronger wave pushing east across the US/Canadian border tonight into Tuesday as a broad upper trough takes shape over the Great Basin. A cold front with the former wave slides southeast through eastern Kansas late tonight into midday Tuesday.
Temps will continue to trend upward tonight into tomorrow as a weak upper level ridge shifts across the Tennessee Valley, with lows tonight several degrees warmer than this morning and highs on Tuesday warming into the mid 50s to mid 60s. Big changes still on track to begin Tuesday night as southwesterly flow increases aloft ahead of a large positive- tilt trough over the western CONUS.
Current surface map places deepening low across southern Alberta with lee trof extending into Wyoming. Upper trof digging across the northern Rockies will move through the Dakotas late today. Initial cold front crosses western South Dakota this afternoon, with arctic front dropping into the area overnight. Main issue today will be the wind, which combined with the low relative humidity, will result in critical fire weather conditions. Winds pick up early this afternoon with pressure rise bubble behind initial cold front. so have upgraded the High Wind Watch to a Warning.
1235 PM EST Mon Jan 31 2022 Dry and warmer weather will be interrupted by a return of mixed precipitation for the mid to late week period. Warm advection with that system and in advance of wrn CONUS troughing will result in a moderation of temperature to just a few degrees shy of the averages for the aftn and the night (37 and 21F at PIT).
203 PM CST Mon Jan 31 2022 Seasonably warm temperatures, periods of stronger winds, and a cold frontal passage tomorrow highlight the short term forecast. An upper-level ridge overhead will continue to push east this afternoon causing the pressure gradient to increase in its wake. Tomorrow, a cold front associated with the low-pressure center currently in southern Saskatchewan will traverse the area from northwest to southeast beginning around 14Z. Its passage will put an abrupt end to our warmer temperatures as northwesterly flow ushers in cool Canadian air behind the front.
This wave will push a cold front south through western Kansas tonight with north to northeast winds and colder temperatures developing behind the front. The Pacific Northwest wave will continue to dig southeast into the Four Corners region by Tuesday evening carving out a deep long wave trough over central North America Tuesday night.
A weak front will move through Deep South Texas overnight, bringing in slightly cooler air for with lows generally in the 50s.
1031 AM MST Mon Jan 31 2022 Current surface map places deepening low across southern Alberta with lee trof extending into Wyoming. Upper trof digging across the northern Rockies will move through the Dakotas late today. Initial cold front crosses western South Dakota this afternoon, with arctic front dropping into the area overnight. Main issue today will be the wind, which combined with the low relative humidity, will result in critical fire weather conditions. Winds pick up early this afternoon with pressure rise bubble behind initial cold front. so have upgraded the High Wind Watch to a Warning.
1244 PM EST Mon Jan 31 2022 Dry high pressure through Tuesday.
134 PM MST Mon Jan 31 2022 Water vapor shows deepening western CONUS trof with strong wave pushing from the Northern Rockies into the Northern Plains. Surface analysis shows deepening low over western SD with Pacific cold front having recently dropped through GCC and KRAP, and arctic cold front pushing into north central MT. Pacific cold front will continue to cross the region this afternoon, with arctic boundary sweeping through late this afternoon and evening.
More snow will develop this overnight, but amounts overnight will still be fairly light, generally a couple of tenths for the lower elevations.
Relative humidity values should quickly recover after sunset this evening with attention then turning toward a series of cold fronts set to traverse the area through the overnight hours. In terms of temperatures, the arrival of the second cold front will rapidly enhance any overnight cooling with this trend continuing into the daytime hours Tuesday.
