This has allowed the skies to clear with Pacific ridging now entering the region in the wake of the cutoff low feature.
Sfc analysis at this hour shows high pressure from N FL across the NE gulf. High pressure will remain in proximity to the region today, with its center settling over the southern third of the peninsula overnight. Expected orientation of high pressure wl bring conds favorable for radiation freeze across the interior south, with widespread frost extending from there into rural areas west of I-95 from greater Melbourne-Palm Bay southward. Widespread mins in the L-M30s, a little warmer again toward the coast and colder (around 30F to perhaps U20s) for the interior south.
A swirl of low pressure, currently spinning over southwest Arizona, has begun to break down the ridge of high pressure overhead. However, these fluid changes up above will barely be noticed to life on the ground today as the low continues an easterly track, undercutting the forecast area. Since this column of cooler air stays to our south, much of the region won't notice its passage, aside from a few high clouds spilling across southwest Colorado and southeast Utah. Low pressure is expected to shoot off into northern Texas tonight, leaving the CWA under weak zonal to northwesterly flow. The first trough takes a quick dive ashore Monday morning, but will take an easterly track across the Northern Rockies. A cooler airmass will sink over the region in conjunction with cloud cover, so anticipate a dip in high temperatures for Monday.
This feature will be followed by rapidly building high pressure well off the coast beginning Monday with increasing northerly winds.
217 AM PST Sun Jan 30 2022 Dry and mild conditions will prevail through Monday ahead of a dry cold front that will bring colder temperatures and increased winds to kick off February. Benign and dry weather will persist with a blocking ridge deflecting the storm track for the Sierra and western Nevada until further notice. The quiet, dry weather pattern continues today and Monday as high pressure dominates across the West. There still isn't any meaningful precipitation to discuss, but high pressure retrogrades just slightly westward to allow for a couple of dry fronts to drop through the region.
The next couple of days should be noticeably warmer than the previous few days.
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 ridging begins to build in on Monday afternoon with dry NW flow aloft. High pressure slides off to the northeast late in the day with weak southeast low-level flow across the region.
1051 AM CST Sun Jan 30 2022 A weak cold front is pushing through the Mid-South this morning. Warmer conditions are in store for the few days.
High clouds will increase across the far south by the end of the day ahead of an approaching upper low over the Southwest. At the surface, low pressure was centered over IN with a weak cool front extending southwest across our area.
1207 PM EST Sun Jan 30 2022 Intense low pressure will exit across the Maritimes today.
CAMs show snow developing on the northern hemisphere of the low. The lack of synoptic-scale lift and incoming mid-level dry air will be major precip deterrents to the low's south. There is a small chance that our northern MN counties see some freezing drizzle as forecast soundings show just enough low-level saturation. A trailing cold front will follow the low, cooling temperatures in its wake.
221 PM EST Sun Jan 30 2022 High pressure along with relatively dry air will remain in control of the region through the middle of the week with a general warming trend.
Highs today are still expected to be in the low 30s for most. A weak cold front will race through central Illinois early this morning accompanied by little more than a few mid/high clouds. Despite the northwesterly flow, ample sunshine will push afternoon highs into the lower to middle 30s everywhere east of the Illinois River. As upper heights continue to rise and winds once again switch around to the S/SW, warmer conditions will arrive by Monday as highs climb into the 40s.
1038 AM EST Sun Jan 30 2022 Light snow is expected today as weak low pressure passes. Snow totals will remain under an inch for the most part, although totals on the ridges may approach an inch with a modest upslope kick.
The mid/upper ridge across the Central Great Basin area is progged to translate eastward over the Rockies tonight before emerging across the Central Plains on Monday resulting in another day with mild and above normal temperatures for the area. low level cold air advection will drive temperatures below freezing in the wake of a cold front. This will allow rain to transition to snow beginning in the evening hours over south central KS while gradually spreading east and southeast across southeast KS overnight into the predawn hours on Wed as an upper trough approaches from the west. The main focus is still across south central and southeast KS where the higher impacts from accumulating snow are anticipated.
Temperatures have warmed into the upper 50s most locations with humidity as low as the low to mid teens. There is also a strong signal for gusty winds ahead of an approaching cold front. Monday night, the cold front drops quickly southeast.
High pressure dominates the area with surface dewpoints and RH quite low across inland locations of central FL. With high pressure settling squarely over the area, optimal radiational cooling will produce a wider area of sub freezing temperatures.
We're beginning to see some of the upper level clouds in advance of an upper level low that will move through the area tonight and tomorrow. Ahead of the low, surface winds will back slightly tonight, helping to advect low level moisture into the area, allowing for warm overnight lows mainly in the 40s. However, the higher totals of close to an inch are expected to be confined to areas southeast of a Brownwood to Sonora line. In addition, due to cold upper level temperatures associated with the low, mid level lapse rates will increase to greater than 7C/km, allowing for the potential for thunderstorms to accompany the showers from late tonight into Monday.
942 AM PST Sun Jan 30 2022 A weak ridge aloft will keep the weather fair and mild through Monday, but nights will be chilly.
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.
A weak upper low will bring light snow mainly in the White Mountains through this afternoon, with gradually clearing skies in central and western Arizona.
222 PM EST Sun Jan 30 2022 We are finally quieting down after yesterdays powerful cold front passage. This is thanks to a large area of high pressure that has moved into the Gulf of Mexico over the weekend.
Weak high pressure across the eastern Gulf of Mexico this afternoon will shift east and weaken tomorrow as a low pressure system tracks across TX on Monday and into the western Gulf of Mexico Monday night. Highs will increase into the mid to upper 60s Monday, about 4-12 degrees warmer then today.
A substantial increase in temperatures to above normal values is anticipated on Monday as the upper flow pattern flattens and low level southerly winds develop on the west side of departing high pressure. Meanwhile, lows in the lower 20s tonight should moderate into the 30s by Monday night.
As high pressure continues to move into the region, winds have relaxed and will remain light through this evening.
/JNE/ Hooray for a warmer day today! With winds being more south/southwest today, warmer flow has entered the region and will help increase air temperatures into the 60s today.
Hooray for a warmer day today! With winds being more south/southwest today, warmer flow has entered the region and will help increase air temperatures into the 60s today.
1123 AM CST Sun Jan 30 2022 An upper level ridge will continue to push eastward across the Western U. Today will be a little bit cooler behind a weak front that moved through.
Stratus is with us again this morning, mainly over Malheur County, but also in northern Harney County and in the Lower Treasure Valley. This will finally be removed tonight as a cold front moves through the area.
/issued 1051 AM CST Sun Jan 30 2022/ A weak cold front is pushing through the Mid-South this morning. Warmer conditions are in store for the few days.
A weak cold front will bring increasing cloud cover and cooler air tonight with lows dropping into the 20s. This cooler air along with thicker clouds will keep highs on Monday down a few degrees from what we are seeing today, but still will be quite mild compared to the recent cold.
An upper level ridge begins to approach the Deep South late tonight and will quickly move across the region on Monday. At the surface, high pressure slides east across the northern Gulf of Mexico this afternoon, before reaching the Florida Panhandle later tonight. Winds will also shift from southwesterly to more westerly as the high moves east tonight. Overnight, lows will be cool due to radiational cooling, but will stay above freezing. Temperatures rebound on Monday with highs topping out in the mid to upper 60s due to the influence of the upper level ridge and southerly flow.
259 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.
The next weather system will move through mid week, bringing widespread gusty winds and cooler temperatures. Dense cloud cover associated with this low will continue to shift eastward as well, leaving behind mostly clear skies and dry northwesterly flow today.
1102 AM EST Sun Jan 30 2022 High pressure along with relatively dry air will remain in control of the region through the middle of the week along with a warming trend.
An upper low will bring scattered -SHRA to the area impacting some TAF sites around 00-06Z. CAMs are highlighting a line showers over the Permian Basin by 00Z and another area of showers over the Lower Trans Pecos. Thunderstorms are expected to trek west to east as the low progress through the region exiting the area by tonight. Lows tonight are forecasted to drop down to the low 30s to low 40s due to increased dew points across the area.
High pressure is quickly establishing itself across the Gulf of Mexico and will dictate the sensible weather for the Florida Keys today.
Clouds are expected to begin to increase in southwest parts of the fa later this afternoon as upper low, over S CA/SW AZ early this morning, moves east and begins to approach the region. This mid/upper low is expected to move into TX tonight.
1010 AM MST Sun Jan 30 2022 Current surface map places trof across eastern Montana into far western South Dakota. Flat upper level ridge is located across the northern Rockies/Plains. If we could get a break in the high clouds, a few 60s are possible. Upper trof moves in the plains Monday, with initial cold front arriving during the day.
623 PM EST Sun Jan 30 2022 High pressure along with relatively dry air will remain in control of the region through the middle of the week with a general warming trend.
605 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.
Monday high pressure starts to build in quickly behind the frontal boundary. High temperatures will be cooler than we have seen in a few days with highs only in the 50s in most areas. Winds on the coast are expected to be around 20 to 30 mph with a few gusts close to 40 mph on the exposed ridges.
We'll see low temperatures in the upper 30s tonight with temps around the low 40s along the coast. Weak high pressure across the eastern Gulf of Mexico this afternoon will shift east and weaken tomorrow as a low pressure system tracks across TX on Monday and into the western Gulf of Mexico Monday night. Highs will increase into the mid to upper 60s Monday, about 4-12 degrees warmer then today.
Dry offshore winds will develop late Monday through midweek across the Bay Area and Central Coast peaks and ridges. This is the result of high pressure aloft ahead of an approaching mid/upper level trough. This mid/upper level trough is forecast to push into the Pacific Northwest in the next 24 hours and then deepen across the Intermountain West into midweek. This will maintain dry weather conditions over the region and bring about another round of offshore winds across the peaks and ridges of the Bay Area and Central Coast.
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.
101 PM PST Sun Jan 30 2022 Dry and mild conditions will prevail through Monday ahead of a dry cold front that will bring colder temperatures and increased winds to kick off February. Benign and dry weather will persist with a blocking ridge deflecting the storm track for the Sierra and western Nevada until further notice. This will increase westerly Sierra ridgetop gusts to 50-60 mph through mid-morning Monday.
/issued 332 PM CST Sun Jan 30 2022/ A weak cold front continues to move through the Mid-South this afternoon. Temperatures will likely be a tad cooler tonight due the light or calm winds.
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.
332 PM CST Sun Jan 30 2022 A weak cold front continues to move through the Mid-South this afternoon. Temperatures will likely be a tad cooler tonight due the light or calm winds.
The clouds will help keep temps up near the warmer guidance, mainly in the upper single digits and teens.
236 PM MST Sun Jan 30 2022 A Pacific storm system and cold front will move across the Northern Rockies from the northwest late this evening through Monday morning. For lower elevations, ambient conditions and precipitation type are anticipated to change quickly overnight through early Monday morning, including a brief bout of freezing rain and sleet mixed in with snow (and even rain for lower elevations of north central Idaho).
445 PM MST Sun Jan 30 2022 Updated Aviation Discussion A cold front will move from west to east across the region on Monday.
A weak upper low will bring light snow mainly in the White Mountains through this afternoon, with clearing skies in central and western Arizona.
High pressure overhead will result in mostly clear skies overnight. The only weather concern tonight will be the potential for some patchy fog or freezing fog in the valleys across northeast Alabama.
scattered high cloudiness is expected to move through northwest flow aloft, ahead of an approaching upper level trough. high clouds increase from the northwest during the latter part of the morning and through the afternoon as the upper trough approaches. Blending the better performing guidance from the past few days suggests high temperatures ranging from the middle 40s to lower 50s in and near the snow pack area to the lower to middle 60s. A cold front moves through during the night shifting winds to the northwest at 10 to 20 mph with some higher gusts.
The exact amount of mixing, combined with evaporative enhancement of downward winds underneath the expected precipitation that will accompany the cold front tomorrow is uncertain enough as to warrant keeping an eye on winds as the day progresses. As a cold front slides through the region, west to northwest winds will increase. A wintry mix is possible as the cold front approaches which will quickly shift over to light snow with the cold air advection. It would not be surprising to see a brief period of freezing rain, especially in the east, but impacts should be minor given light QPF and quick transition to snow.
126 PM PST Sun Jan 30 2022 A weak ridge aloft will keep the weather fair and mild through Monday, but nights will be chilly.
437 PM EST Sun Jan 30 2022 A cold front is just about to exit southeast out of KY late this afternoon, part of a weak clipper-like system. The surface ridging slips to our east on Monday night, and modest warm air advection returns as low level flow shifts toward the south. This will result in more noticeable ridge/valley low temperature differences.
The upper level low that brought plenty of high and mid level clouds yesterday with slightly cooler temperatures has moved into SRN New Mexico. Weak short wave ridging tonight will quickly get squashed as a cold trough will drop into the Great Basin from the PACNW on Monday.
Expect one more day with high pressure and warmer temperatures aloft. High pressure is breaking down today ahead of a Pacific trough and associated cold front. Expect breezy to moderate winds on Monday with an overall weak cold front moving through. Temperatures will likely rise above freezing for the first time in weeks for a few locations along I-86 and the southwest portions down low across our area.

240 PM MST Sun Jan 30 2022 The ridge will continue to weaken as more energy moves into the area. This evening will see the foothills winds from Livingston to Nye increasing as lee-side troughing strengthens.
Given the low dewpoints, overnight min temps are still on track.
224 PM MST Sun Jan 30 2022 A cold front will move from west to east across the region on Monday.
A Freeze Warning remains in effect for Southern Brevard, Indian River, Saint Lucie, Okeechobee, and Osceola Counties where widespread frost and freezing temps in the low 30s. High pressure settling over the south-central FL peninsula tonight will produce calm winds, and combined with clear skies allows strong radiational cooling to occur. High pressure will orient east of the area by Monday afternoon with modest onshore flow conditions beginning to develop by afternoon. High pressure builds into the local area tonight and Monday, with favorable boating conditions to start the week - variable winds less than 10KT and seas 2-4FT.
Therefore, have decided to upgrade the High Wind Watches here to Warnings. However, Monday night, humidities should have pretty good recoveries as a cold front approaches from the northwest.
753 PM EST Sun Jan 30 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.
208 AM CST Mon Jan 31 2022 Nice and quiet at forecast time across the mid-state, but it's definitely warmer than the last several mornings.
A ridge of high pressure at the surface and aloft will move over the forecast area through Tonight.
Only minor update was to adjust overnight lows to fall in line with current temperature trends, as a couple of site are running warmer than expected.
Current forecast has a good handle on much cooler temperatures across our northern and northeastern third compared to somewhat milder temperatures to our west.
1258 AM EST Mon Jan 31 2022 A weak area of low pressure will move southeast across the area tonight. High pressure will then remain over the area through mid week. A slow moving cold front will approach late this week. Good radiational cooling will continue inland, and lows should reach the mid to upper 20s inland, and the low to mid 30s near the coast. Weak low will shift off the coast Monday morning with strong high pressure ridging into the Carolinas from the north.
1044 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.
Clear skies will be in place across the area under high pressure. 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.
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.
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. 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.
Our pressure is 1024-1023 across the Lower Keys, which means this high is very close to the Keys. If winds can decouple for an hour or two across the Lower Keys, some locations will be colder tonight than last night.
Portions of the interior have dropped to near or just below freezing in Glades, Hendry and inland Collier Counties. Inland areas, particularly rural areas South of Lake Okeechobee have little to no wind and temps just above freezing creating favorable conditions for frost development. As we start the work week, an area of high pressure will slowly be moving eastward over South Florida will continue to dominate weather conditions for the region.
953 PM CST Sun Jan 30 2022 (Issued 1000 PM CST Sun Jan 30 2022) Some pesky low clouds remains across parts of the region but otherwise weak high pressure dominates the region with light winds and no concerns for precip. Breezy sly winds and warm advection will increase Mon into Tue AM as strong low pressure tracks ewd across srn Canada. The cold front will pass Tue afternoon. Temps will approach the freezing mark on Mon and rise into the upper 30s to lower 40s on Tue.
High pressure overhead will result in mostly clear skies overnight. The only weather concern tonight will be the potential for some patchy fog or freezing fog in the valleys across northeast Alabama. Overnight low temperatures Monday night will be near average, dropping into the low to mid 30s. The aforementioned southern stream cutoff low over the Gulf of Mexico will generate a convergence axis east of the Lower Mississippi Valley. Longwave troughing will set up over the Central CONUS in the southern stream of the split flow jet pattern, placing the Southeast in southwest flow aloft for the remainder of the week - another favorable pattern for heavy rainfall.
324 AM EST Mon Jan 31 2022 Temperatures this morning are near the upper 40s for most of the Keys, and temperatures could drop to the lower to middle 40s due to clear skies and relatively calm winds. High pressure over the region will create fair and stable weather conditions through the middle of this week, with rain chances less than 12 percent over the next seven days. The low rain chances result from meager moisture content in the atmospheric column due to the arctic air mass pushing the rich tropical moisture in the Caribbean waters. The high pressure will slide east this afternoon and cause the winds to shift to the northeast to east, bringing an onshore flow and scant moisture back to the region.
