As ridging builds in this afternoon and tomorrow, temperatures are expected to warm back up near normal. High pressure will result in a mostly clear sky, with a few mid to high level clouds, light winds, and VFR conditions prevailing through the period.
Clouds will be on the increase with locally gusty winds developing overnight and on Tuesday as a cold front approaches.
1111 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.
/Issued 622 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.
Portions of the interior earlier today dropped to near or just below freezing in Glades, Hendry and inland Collier Counties where Freeze Warnings and Frost Advisories were in effect, but these products will not be needed tonight as South Florida temperatures begin to moderate and we defrost from this cold snap. An area of high pressure is slowly moving eastward over South Florida and will continue to dominate weather conditions. Low temperatures tonight will begin to moderate ranging from the low 40s across the interior upper 50s along the east coast. Highs on Tuesday will reach the low to mid 70s across the entire region.
225 PM EST Mon Jan 31 2022 Dry high pressure through Tuesday.
1136 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.
1222 PM EST Mon Jan 31 2022 Dry high pressure Monday and Tuesday.
1100 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.
However, a cold front will move through the region late on Tuesday morning shifting light winds to the north and increasing to around 15kt. /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.
(This evening through Tuesday) An upper level low is currently tracking across West Central Texas, with isolated showers occurring across our southeast counties. This activity is forecast to move east of our area by late this afternoon, as the aforementioned upper level low also moves east of the region.
A cold front has moved through the area overnight and this morning, bringing gusty winds and snow showers to the mountains. Gusts 30 to 50 mph were observed at some of the higher elevation RAWS sites, with 20 to 30 mph at a few of the lower elevation sites. After a lull in snow shower activity over the mountains this afternoon, we expect a few more tonight, especially in the higher terrain of Baker County and the West Central Mountains of Idaho. Temperatures will be 5 to 10 degrees warmer in the lower elevations today, even though a cold front just moved through, because the inversion has been scoured out.
/issued 1045 AM CST Mon Jan 31 2022/ A broad area of high pressure covering much of the eastern US is shifting gradually east. Light southerly flow is developing across the area as low pressure develops over the central US today. A warm front will lift northward across the Midsouth today shifting winds from the south and ushering in higher moisture levels.
139 PM EST Mon Jan 31 2022 High pressure remains almost directly overhead this afternoon, with plenty of sunshine and temperatures in the 60s area-wide.
1045 AM CST Mon Jan 31 2022 A broad area of high pressure covering much of the eastern US is shifting gradually east. Light southerly flow is developing across the area as low pressure develops over the central US today. A warm front will lift northward across the Midsouth today shifting winds from the south and ushering in higher moisture levels.
1052 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.
a strong cold front will move into eastern ND toward 06z and pass into MN 10z period.
547 PM CST Mon Jan 31 2022 For the 00Z TAFs, a strong cold front will move across the terminal sites late tonight and will be accompanied by gusty north winds in its wake for much of this forecast period. Upper closed low is positioned over southern Texas today and continues to move southeast into the GoM tonight into tomorrow morning. Winds aloft will turn westerly late tonight and become more southwesterly tomorrow as the next trough digs into the western CONUS. This will bring a cold front through the area starting around midnight across the Oklahoma Panhandle. Areas across the far southeast Texas Panhandle may see temperatures rise into the lower to mid 50s.
Still a couple more hours where the band could bring some light snow or some freezing drizzle to northern Door County, but this chance will fade after sunset. Tight pressure gradient remains in place through the night as low pressure pushes across southern Manitoba. as low pressure works across southern Canada, a cold front will swing across the area through the day. Looks like the area will miss out of any of the heavier precip as it will reside closer to the low to our north and where better moisture is available along the front to our south.
621 PM EST Mon Jan 31 2022 Dry high pressure through Tuesday.
Upper closed low is positioned over southern Texas today and continues to move southeast into the GoM tonight into tomorrow morning. Winds aloft will turn westerly late tonight and become more southwesterly tomorrow as the next trough digs into the western CONUS. This will bring a cold front through the area starting around midnight across the Oklahoma Panhandle. Areas across the far southeast Texas Panhandle may see temperatures rise into the lower to mid 50s.
641 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.
Mostly clear and dry conditions tonight with light to calm winds as high pressure remains atop the region. Not as cold, though still chilly with overnight lows in the low to mid 40s. (Modified Previous Discussion) High pressure over FL will depart eastward and build into the western Atlantic. Onshore flow increases through the day, bringing warmer and slightly more moist air to east-central FL. Seasonable afternoon highs in the lower 70s. Favorable boating conditions persist through mid week as high pressure maintains dry conditions.
709 PM CST Mon Jan 31 2022 Freezing rain, sleet or ice pellets and snow have been observed at Grand Forks in the last hour. a strong cold front will move into eastern ND toward 06z and pass into MN 10z period.
Forecast Summary: - Warm weather comes to an end as a cold front moves through this evening.
peaked above freezing this afternoon and will quickly fall beginning in the early-evening hours.
551 PM CST Mon Jan 31 2022 (This evening through Tuesday) An upper level low is currently tracking across West Central Texas, with isolated showers occurring across our southeast counties. This activity is forecast to move east of our area by late this afternoon, as the aforementioned upper level low also moves east of the region.
A cold front will drop quickly southeast this evening. Going into Tuesday night, A positevly tilted upper trough will extend from the Desert Southwest through the Northern Plains, joining up with a deep closed upper low centered over northern Manitoba. This upper trough will begin to saturate the atmospheric column from the Four Corners Region to areas just to our west and south. Increasing isentropic upglide shown by the 12Z GFS indicates the potential for saturation and low pressure deficits.
A ridge of high pressure over the eastern Pacific and an upper level trough over the central USA will keep the Pacific Northwest under a cool northwest flow.
Winds have turned to the southwest behind a trough of low pressure this afternoon. A cold front will move into the area Tuesday morning and turn winds to the northwest. The cold front will keep temperatures from warming much during the day, especially in the northern part of the forecast area.
520 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.
High pressure building off the coast will lead to gusty northerly winds across much of the region over the next few days. High pressure is building into the area this afternoon. Winds will be breezy over the ridges, especially towards morning. Freezing temperatures are expected nearly out to the coast and temperatures may drop into the teens in the coldest valleys.
922 PM EST Mon Jan 31 2022 Dry high pressure through Tuesday.
In fact, at one point, skies were completely free of clouds (SKC) throughout most of the lower and middle Keys, a rare occurrence. The combination of building high pressure along the Eastern Seaboard and lowering pressures across the western Gulf basin will result in freshening and veering easterly breezes beginning this evening, peaking mid-week, and diminishing somewhat toward the end of the week. Small Craft Advisories will go into effect for Hawk Channel and the Straits of Florida tonight tonight as northeast to east breezes freshen in response to an expanding high pressure cell along the Eastern Seaboard combined with lowering pressures over the western Gulf of Mexico.
627 PM EST Mon Jan 31 2022 Southerly winds on the backside of retreating high pressure will bring milder temperatures overnight and Tuesday.
Once the overnight hours commence, the western half of the region begins to show slowing winds, while the eastern half of the region is likely to get further wind enhancement as the low pressure center (currently lagging a bit behind the cold front) swings closer and through to the east. 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.
655 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. Quiet night ahead with much warmer temperatures when compared to Monday morning lows.
Clouds will be on the increase tonight and Tuesday as a cold front approaches.
High pressure will continue drifting east in the short term with very pleasant weather across the Mid-South. By afternoon we will start picking up some clouds as the front approaches the I-44 corridor in MO and low pressure develops over the Red River Valley.
Once the overnight hours commence, the western half of the region begins to show slowing winds, while the eastern half of the region is likely to get further wind enhancement as the low pressure center (currently lagging a bit behind the cold front) swings closer and through to the east.
Tomorrow, we will have a southerly flow behind the ridge that will warm temperatures into the mid 50s to lower 60s. VFR through the period at all sites as high pressure transitions east across the area.

Total snow from 00Z tonight to 00Z Wednesday should be a tenth of an inch in Baker City, around an inch in McCall, and 3 to 6 inches in the highest peaks. A secondary surge of cooler air, along with breezy northwest winds, will arrive Tuesday night, so it will be noticeably windier than normal Wednesday morning as most folks start their day.
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. Southerly flow become well established across our area as high pressure moves out over the western Atlantic.
This area of snow will continue to spread to the east as the low pressure system slides across Manitoba. Will continue to see west winds on the SW quadrant of the clipper system be realized overnight with gusts to 60mph still expected as the cold front pushes south across the area overnight. Freezing rain, sleet or ice pellets and snow have been observed at Grand Forks in the last hour. a strong cold front will move into eastern ND toward 06z and pass into MN 10z period.
1020 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. Mid/upper wave moves through late Tuesday night into Wednesday, with strengthening inverted trof extending northward into northeast WY and southwest SD.
A ridge of high pressure over the eastern Pacific and an upper level trough over the central USA will keep the Pacific Northwest under a cool northwest flow. Under north-westerly flow behind the cold front and trough, the main concern will be mountain snowfall in the Cascades and Blues tonight into tomorrow. For the Cascades, a continuance of activity along the higher terrain is expected, primarily impacting the Western side of the mountains, but moving into the peaks and some spillage over. Moving beyond immediate concerns, as the trough continues away from the region and ridging offshore overspreads more inland, we move into more northerly flow through Wednesday.
334 AM EST Tue Feb 1 2022 High pressure along with relatively dry air will remain in control of the region today.
A cold front will drop quickly southeast this evening. Going into Tuesday night, A positevly tilted upper trough will extend from the Desert Southwest through the Northern Plains, joining up with a deep closed upper low centered over northern Manitoba. This upper trough will begin to saturate the atmospheric column from the Four Corners Region to areas just to our west and south. Increasing isentropic upglide shown by the 12Z GFS indicates the potential for saturation and low pressure deficits. The highest amounts near 3 inches would be across far southwestern areas (western Deuel and southwestern Chase County).
The first player will be a weakening upper level low moving across Texas and into the central Gulf on Tuesday. By Tuesday night, the upper trough will weaken and is absorbed within the broader deeper southwesterly flow. This is when the main contender enters stage left as a deep positively tilted upper trough digs into the rockies. Lows on Tuesday night will range from the low 50s over the northeastern counties to upper 50s along the coast and southwestern counties.
Shasta, CA progresses east ashore central CA -- and [4] a deamplifying upper level low in the Pacific, currently situated ~1000 mi west Los Angeles, moves ashore southern CA and progresses eastward into the Desert Southwest.
1218 AM EST Tue Feb 1 2022 Dry high pressure today.
Temps are generally in the lower 30s across the area this afternoon with some pockets of mid 30s in the metro area and mid/upper 30s across the south. Highs on Tuesday should reach the lower 40s for most of the area, though its possible some areas across the northwest may only reach the upper 30s before a cold front reaches the area in the afternoon and temps begin to slowly fall.
peaked above freezing this afternoon and will quickly fall beginning in the early-evening hours. The best chances for any accumulating LES will be across the Keweenaw first in the southwest flow tomorrow morning and continuing through Wednesday when winds become northwesterly behind the aforementioned cold front.
1054 PM CST Mon Jan 31 2022 (This evening through Tuesday) An upper level low is currently tracking across West Central Texas, with isolated showers occurring across our southeast counties. This activity is forecast to move east of our area by late this afternoon, as the aforementioned upper level low also moves east of the region. Above normal temperatures are forecast on Wednesday with highs in the low to mid 70s.
and Wednesday An arctic cold front will sweep through the region during the day today, ushering in a much colder airmass across the western Great Lakes region. Cold temperatures and dry weather will continue on Wednesday as high pressure builds in across the northern Plains as a low pressure system passed well to our south across the Ohio Valley.
1234 AM EST Tue Feb 1 2022 High pressure will give us one more day of dry weather before a low pressure system develops and pushes high pressure east. With the region under the influence of high pressure, mainly clear skies through the night will slowly give way to increasing cloud cover through dawn. Easterly flow through the overnight and into the day will allow for warmer temps in downslope flow. The mid to late week period is gaining a bit of consistency as the eventual cntrl CONUS longwave trough/cold front is progged to encroach on the Ohio Valley. As this occurs, continued deep southwest flow will advect moisture and warmer air over the region.
228 AM EST Tue Feb 1 2022 High pressure along with relatively dry air will remain in control of the region today followed by a gradual warming trend. Unsettled weather associated with an approaching cold front is expected late in the week.
1043 PM EST Mon Jan 31 2022 Currently - The combination of ridging across Florida and a weak low centered over the northwestern Gulf of Mexico has tightened the pressure gradient across our area and brought about freshening northeast to east breezes. Temperatures are in the lower 60s with dew points in the lower to mid 50s. However, the cooler and drier air along and north of the Keys has limited the stratocumulus reaching the island chain. Sky cover will gradually increase as stratocumulus gradually makes further inroads A tightening pressure gradient due to a ridge to our north and low pressure centered in the western Gulf of Mexico will result in breezes continuing to freshen across Keys waters through the overnight period.
254 AM EST Tue Feb 1 2022 High pressure will give us one more day of dry weather before a low pressure system develops and pushes high pressure east. With the region under the influence of high pressure, mainly clear skies through the night will slowly give way to increasing cloud cover through dawn. Easterly flow through the overnight and into the day will allow for warmer temps in downslope flow. The mid to late week period is gaining a bit of consistency as the eventual cntrl CONUS longwave trough/cold front is progged to encroach on the Ohio Valley. As this occurs, continued deep southwest flow will advect moisture and warmer air over the region.
903 PM PST Mon Jan 31 2022 High clouds will continue to spread in from the west through Tuesday as a weak trough approaches Southern California. Lower clouds will thicken as well, as cooler marine air spreads well inland.
300 AM CST Tue Feb 1 2022 While temperatures have been stable overnight, cold air advection ramps up today behind a surface cold front currently draped from western Minnesota to eastern Nebraska. Winds will remain elevated in wind prone areas west of the Mississippi River into the overnight hours before 850mb winds turn northerly and exhibit restraint under influence of lee anticyclone. Timing and location of the amplifying upper level trough and associated favorable regions of ascent remain more towards the Mid-Mississippi River Valley.
Expansive ridging over the western Atlantic Ocean has allowed for increased east/northeasterly flow across the region.
1058 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.
250 AM CST Tue Feb 1 2022 The initial cool down that will have us trending toward much colder temperatures will occur today as a cold front moves through the forecast area. The cold front will be south of the FA by tomorrow morning. Currently a mixture of freezing rain, snow, and liquid rain will be most probable across much of the FA given the presence of a warm nose. Currently rain and freezing rain look to be most likely across the far southeastern Rolling Plains. Any liquid or freezing rain should quickly change over to snow not too long after the onset of precip thanks to dynamic cooling.
1007 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.
For now, did not go below 1000ft and left the lowest CIGS around 1500ft. An upper level low is currently tracking across central Texas and is expected to reach the western Gulf of Mexico. It will be weakening into an open trough as it does so. That will probably diminish the chances for thunderstorms tomorrow as showers begin developing on the leading edge of the trough. However, slow movement of the trough could mean training of showers along the Atchafalaya Basin. Some showers will be lingering across the area beyond that in this period of the forecast but the nearly non- existent trough at this point means not much of a focus or enhancement of convection expected.
Increasing clouds tonight and Tuesday as a cold front approaches. Passage of the cold front Tuesday night into Wednesday will bring a chance for snow along with cold temperatures and gusty winds.
Nevertheless, overnight temperatures will still be near the lower 60s for most of the Keys.
