357 AM MST Tue Jan 11 2022 08z surface analysis had warm front from southern SK to eastern KS.
The last of the lake-enhanced snow showers will end this morning with building high pressure.
High pressure will maintain dry and stable conditions across the region through much of the week.
418 AM CST Tue Jan 11 2022 High pressure will move east of the region today, allowing for southerly flow over the next couple of days. High temperatures should favor warmer guidance values, given expected sun, and S/SW surface flow.
630 AM EST Tue Jan 11 2022 High pressure centered over the region this morning will quickly move east today.
517 AM CST Tue Jan 11 2022 (12Z TAFS) Satellite shows extensive area of mid clouds around 10KFT in assocn with shrtwv trof. There is enough lift e of the trof axis for some shallow mid clouds and virga which will be the case until 18Z-21Z when the mid-level moisture exits the far ern CWFA. Sunny skies, dry nw flow aloft, and dry surface air will promote noticeably warmer high temps Wed PM, about 5-10 degrees above normal.
Expect highs in the lower to middle 50's both days, with morning temperatures starting in the upper 20's to lower 30's, with middle 30's nearer the coast.
Dry weather and above normal temperatures are expected to hold over our region the rest of the week as a broad ridge of high pressure keeps a cut-off low circulating off the Baja and Southern California Coasts.
355 AM CST Tue Jan 11 2022 (Issued 355 AM CST Tue Jan 11 2022) Today through Wednesday Night: Warm air advection in the low to mid levels picks up this morning with temperatures expected to rise through the day with a few areas even hitting the 30 degree mark this evening. The main reason we'll see these strong winds is due to the 850mb low level jet with wind speeds around 65 knots that moves overhead and a strengthening surface pressure gradient as high pressure moves to the east and low pressure tracks through northern Ontario. Additionally the "warmer" temperatures continue with highs Wednesday in the low to mid 30s across the area. This is short lived though with the cold front moving through Wednesday night and temperatures dropping into the teens to low 20s.
Looking at Grand Forks hitting the freezing mark in the early afternoon. Breezy, westerly winds, and temperatures now in the 20s over most of central North Dakota will help the seasonally warm temperatures spread east today, with portions of eastern North Dakota potentially breaking the freezing mark. With temperatures possibly in the low 30s, these highs are still significantly cooler than record temperatures in the mid 40s. SREF/NAM also show max wetbulbs aloft below freezing during the 06Z to 18Z timeframe and, while the GFS is warmer aloft, as mentioned above, it is also dry. So leaning towards SREF/NAM p-types, expecting mostly snow with the possibility of some very patch freezing drizzle that should have minimal impacts.
Ensembles favored a more stable large-scale flow pattern as high pressure aloft amplifies over the Desert Southwest keeping the main storm track well north of the area. Thus, the prospects of rain and mountain snow showers will be delayed until the large-scale blocking pattern breaks down.
309 AM CST Tue Jan 11 2022 Light rain showers were attempting to develop across the southern South Plains early this morning as a compact upper low was crossing the Pecos. Very dry air in the lowest 5000 feet of the atmosphere was significantly decreasing the efficiency of these showers. This upper low will cross the southern South Plains midday then pull east with dry northwest flow aloft to follow. Today will see near normal or slightly warmer than normal temperatures. RMcQueen An upper-level ridge will begin to push east across the Desert Southwest Wednesday, as an upper trough over the eastern CONUS slowly moves east. Upper heights over our region will start to increase, as the ridge to our west moves closer to the area, resulting in temperatures increasing going into the middle and latter part of the week.
Shallow arctic cold front pushing in from the north is not likely to produce much more in the way of accumulation over the NW given current trends and inversion heights. Flow backs toward northerly later this morning as high pressure shifts east across the lower Great Lakes.
Strong gusty winds and warming temperatures prevail across much of central and north central Montana today, while cooler temperatures continue across the southwest valleys. A weak upper level North Pacific Trof is located along The Canadian West Coast, with a downstream upper level trof located along the Canadian and U. The afore mentioned upper level Baha Low moves southward, and The North Pacific upper level high slides eastward toward The California west coast. Throughout the day, tomorrow, an upper level ridge builds along The U. As the upper level ridge axis enters western Montana, wind/wind gust speeds begin to decrease.
510 AM CST Tue Jan 11 2022 Key Takeaways: A stout ridge has developed over the Rockies and northwest flow aloft has taken shape over the Central Plains.
313 AM MST Tue Jan 11 2022 Strong gusty winds and warming temperatures prevail across much of central and north central Montana today, while cooler temperatures continue across the southwest valleys. A weak upper level North Pacific Trof is located along The Canadian West Coast, with a downstream upper level trof located along the Canadian and U. The afore mentioned upper level Baha Low moves southward, and The North Pacific upper level high slides eastward toward The California west coast. Throughout the day, tomorrow, an upper level ridge builds along The U. As the upper level ridge axis enters western Montana, wind/wind gust speeds begin to decrease.
Pleasant winter weather continues as high pressure continues over the region. A ridge of high pressure aloft will continue to build ahead of a rapidly moving trough which is expected to reach the coast on Wednesday night. A continuation of the nice winter weather pattern looks to continue as nearly 80% of clusters show ridging quickly building back in, for more warm, dry weather back for the weekend.
400 AM PST Tue Jan 11 2022 Through Wednesday, warmer weather with low inland humidity and gusty Santa Ana winds will continue with the winds gradually decreasing in strength and coverage.
Not much sensible weather to come out of this system with maybe some slightly cooler temperatures across portions of the plains.
943 AM EST Tue Jan 11 2022 A weak cold front pushed through the Keys overnight and is currently positioned over the Florida Straits south of the islands. However, as the cooler and drier air continues to filter in from the Gulf, the ill- defined surface boundary will become oriented more from the northeast to southwest.
321 AM CST Tue Jan 11 2022 High pressure will move east of the region today, allowing for southerly flow over the next couple of days. High temperatures should favor warmer guidance values, given expected sun, and S/SW surface flow.
|The upper level ridge axis will be located through the Great Basin with northwest flow aloft over Colorado on Wednesday.
Tranquil conditions across the Tennessee Valley region this morning, with high pressure remaining in control of the weather. The low-level ridge will shift to the east overnight with a return of light southerly to southeasterly flow. Highs on Wednesday will climb into the low to mid 50s.
High pressure will result in a clear sky, calm wind, and VFR conditions at all sites through the period. High pressure with clear sky and cool temperatures.
1259 PM EST Tue Jan 11 2022 High pressure will support dry and warmer conditions through Wednesday.
However, tomorrow will see mild temperatures again, and with that, likely more aggressive melting, since the snow pack will not have all of the mirror finish anymore and it's over all temperature will warmer than this morning. Tonight's lows, with lighter winds, will drop to the lower to mid 20s over snow, and upper 20s over any snow free areas in the southern 1/2.
150 PM EST Tue Jan 11 2022 A very cold airmass will remain in place through the first half of tonight, then as high pressure moves to our east, mercury levels will actually rise late tonight through Wednesday with temperatures climbing back above normal.
The surging warm air advection has allowed temperatures to heat up this afternoon into the low 30s, reaching above freezing in some spots. Looking ahead to tomorrow, seasonal temperatures in the low to mid 20s will be in store for us with much less wind than today.
This will help advect in slightly warmer temperatures overnight into tomorrow, and aid in temperatures in being a few degrees warmer.
With the lack of cooler air behind the front overnight lows are expected to fall into the 20s.
230 PM EST Tue Jan 11 2022 High pressure will continue to gradually shift offshore tonight into Wednesday.
Will need to watch the highs, especially over south central SD, where the latest RAP/HRRR are indicating highs rising into the lower 50s, or a few degrees warmer than the going forecast. An area of low pressure will cross the Northern Plains today, bringing much above average temperatures, along with breezy westerly winds. Slightly cooler air moves into the area on Wednesday with highs ranging from the upper 20s, in western MN, to the upper 40s, in central South Dakota.
This activity should fade through midday as high pressure shifts east across the lower Great Lakes. Mainly clear to partly cloudy tonight with seasonably cold minTs in the 10-15F range (+5-10F warmer over the NW 1/2 of the CWA).
1106 AM PST Tue Jan 11 2022 Bands of light snow and freezing rain will develop over the Inland Northwest today. Temperatures on Wednesday should be warm enough for precipitation to be mainly rain in the lowland with isolated pockets of freezing or mixed precipitation in the northern Cascade Valleys.
1210 PM EST Tue Jan 11 2022 High pressure provides dry weather through Wednesday. A high pressure system will slide eastward, allowing for southerly winds tonight into Wednesday.
245 PM EST Tue Jan 11 2022 High pressure heads toward the coast by late this evening.
317 PM EST Tue Jan 11 2022 High pressure provides dry weather through Wednesday. A high pressure system will slide eastward, allowing for southerly winds tonight into Wednesday.
1140 AM CST Tue Jan 11 2022 Key Takeaways: A stout ridge has developed over the Rockies and northwest flow aloft has taken shape over the Central Plains.
121 PM EST Tue Jan 11 2022 A very cold airmass will remain in place through the first half of tonight, then as high pressure moves to our east, mercury levels will actually rise late tonight through Wednesday with temperatures climbing back above normal.
244 PM CST Tue Jan 11 2022 Behind the passing dry cold front, temperatures have risen to near the NBM 90th percentile. Combined with weaker mixing, this pattern should yield a slightly cooler day than today, but still much warmer than normal with a lighter northwest wind.
245 PM EST Tue Jan 11 2022 High pressure is building into the area today, with mostly clear skies in place across all but the southern-most zones and NE flow subsiding a bit in its gustiness, though an evening surge is expected especially along the coast through around midnight.
This along with clear skies will allow for lows to dip into the low 20s/low 30s overnight area wide. Upper ridging will begin building across the western CONUS later tonight through tomorrow afternoon and will place the FA under northwesterly flow aloft. A weakness within the eastern side of the ridge will move mostly to our south but will still bring a weak front southward late tomorrow afternoon.
Wind speeds will not be as high along this trough.
The longwave upper-level trough has moved off the Eastern Seaboard this morning. Lows tonight will generally be in the low to mid 30s, with some upper 30s along the immediate coast.
933 AM CST Tue Jan 11 2022 Tranquil conditions across the Tennessee Valley region this morning, with high pressure remaining in control of the weather. The low-level ridge will shift to the east overnight with a return of light southerly to southeasterly flow. Highs on Wednesday will climb into the low to mid 50s.
Global models and CAMs spit and sputter precip ahead of the trough with the most agreement occurring over eastern MN into western WI. While snow is likely and amounts will be minimal, a brief period of freezing rain/drizzle could mix in before the low-level warm nose cools.
The waters around the Lower Keys may be a bit more stable from the cooler and drier air feeding in from the Gulf.
1050 AM CST Tue Jan 11 2022 After a cold start this morning with freezing temperatures across the board, we continue to warm up nicely under abundant sunshine and very light winds due to dominant high pressure at the surface. High pressure is all over the four state area with a 1035mb contour running all along I-20 and a few 1036mb readings for the highest in the Natural State. Otherwise, our skies tonight will be slowly clearing toward daybreak south of I-20 and overnight lows will be warmer in the upper 30s. Elsewhere to the north and east, skies will be clear to fair with more patchy frost likely with air temps down in the lower to middle 30s. We can expect partly cloudy skies and southerly winds picking up on Wednesday that will boost temps back above average in the lower 60s.

The forecast is on track with some moderation in the typically coldest areas, and just a couple degrees cooler in the warmer areas like the foothills, Denver, and Palmer Divide due to weak cold advection. The upper level ridge axis will be located through the Great Basin with northwest flow aloft over Colorado on Wednesday.
(Through tonight ) Clear skies and south winds have allowed for warmer temps this afternoon.
/issued 313 AM CST Tue Jan 11 2022/ Light rain showers were attempting to develop across the southern South Plains early this morning as a compact upper low was crossing the Pecos. Very dry air in the lowest 5000 feet of the atmosphere was significantly decreasing the efficiency of these showers. This upper low will cross the southern South Plains midday then pull east with dry northwest flow aloft to follow. Today will see near normal or slightly warmer than normal temperatures. RMcQueen An upper-level ridge will begin to push east across the Desert Southwest Wednesday, as an upper trough over the eastern CONUS slowly moves east.

334 PM EST Tue Jan 11 2022 Discussion/Marine - Light snow possible Wednesday afternoon - A cold front sags into Lower Michigan tomorrow afternoon and the models have been consistent in showing a streak of snow moving through the area.
Latest objective analysis shows a complex pattern in place with a cutoff low located near the Texas Panhandle and another one located west of Baja California, with a ridge nosing in from the eastern Pacific into the western United States in between these features.
1121 AM CST Tue Jan 11 2022 H5 pattern tonight has a broad trough of low pressure extending from Quebec south southwest into the Mid Atlantic states. West of this trough, broad northwesterly flow extended west toward the central and northern Rockies. A ridge was present from Wyoming north into western Saskatchewan. At the surface, weak low pressure was present over northwestern South Dakota. With good agreement noted between the MET and MAV guidance today, went ahead and utilized a blend for the high temp forecast. Highs today will generally be in the lower to middle 50s with readings around 50 in SW Nebraska and the SE Nebraska Panhandle. This will allow temps to reach well into the lower to middle 50s for Wednesday for all locations as snow cover is expected to be gone by Wednesday.
Lucie counties, as high pressure over the Southeast U. Afternoon highs will be in the Low 70s to upper 60. Cool and clear tonight, with overnight lows in the lower 50s across the interior, upper 50s along the coast, and lower 60s along the Treasure coast and Lake Okeechobee.
There is enough lift e of the trof axis for some shallow mid clouds and virga which will be the case until 18Z-21Z when the mid-level moisture exits the far ern CWFA. Sunny skies, dry nw flow aloft, and dry surface air will promote noticeably warmer high temps Wed PM, about 5-10 degrees above normal.
An upper-level ridge is slowly starting to build over the area which will keep the weather generally quiet the next few days. Weak U/L impulses may sweep atop the building ridge bringing a bit more clouds but this would be the most significant thing we see. Otherwise the high continues to build into Wednesday allowing for seasonal temperatures and mainly precip free conditions to continue.
Some freezing drizzle is possible Wednesday afternoon as the mid level moisture scours out; however, the impact from this should be low given it is expected to fall during the afternoon hours.
High pressure will move east of the region today, allowing for southerly flow over the next couple of days. High temperatures should favor warmer guidance values, given expected sun, and S/SW surface flow.
1222 PM EST Tue Jan 11 2022 High pressure centered over the region this morning will quickly move east today.
236 PM CST Tue Jan 11 2022 Temperatures this early afternoon were in the low 30s for the far southwestern portions of the area. Much of the region could see some light precipitation, but model guidance has the higher chances tracking from west central Minnesota into south central Wisconsin. With plenty of WAA yesterday into today in the 925 to 850 mb layer, max temperatures aloft remaining above freezing would result in freezing rain. However, max wet bulb temperatures aloft being below freezing would result in snow. Although as the system departs, loss of ice aloft would lead to the potential threat for freezing rain/drizzle. If the freezing rain/drizzle comes to fruition, it would be very brief for any given location.
1050 AM MST Tue Jan 11 2022 08z surface analysis had warm front from southern SK to eastern KS.
A broad upper ridge will help push Pacific systems into Canada through Wednesday with northeast Montana remaining dry and quiet with continued above normal temperatures.
A weak cold front will bring a chance for light rain or snow showers late Wednesday, but most areas will stay dry.
Highs will reach the 60s tomorrow under full sunshine and strengthening mid-level ridge over the southern plains.
Today Through Wednesday Night The pattern with an upper ridge over the west and an upper trough over the east will continue to bring a northwest flow over Arkansas through Wednesday. Lows tonight Wednesday night will be in the lower to mid 30s.
1250 PM PST Tue Jan 11 2022 High pressure will remain over the area through Wednesday keeping the weather dry and temperatures at or near seasonal normals.
With westerly winds failing to go calm, expect temperatures to remain mild tonight with lows ranging from the low teens north central to the upper 20s southwest.
928 PM EST Tue Jan 11 2022 High pressure will continue to gradually shift offshore tonight into Wednesday.
With increased cloud cover, temperatures will remain a little warmer overnight with lows in the mid 40s to mid 50s.
Continued the High Wind Warning for WY Zone 110 until 12Z Wednesday.
215 PM MST Tue Jan 11 2022 The afternoon analysis shows the upper ridge rebuilding over the west coast producing northwesterly flow aloft over the northern plains.
Precipitation is expected to be light and mixed rain, snow and freezing rain. It doesn't take much freezing rain, a glaze or more, to bring slippery conditions on roads. Areas with the potential for light freezing rain are generally north of the I-90 corridor in western Montana as well as across North Central Idaho. Given this widespread mixed precip we have issued a winter weather advisory for light freezing rain. Wednesday afternoon a ridge of high pressure will amplify over the region and persist for 24 hours. The ridge will be favorable for a return of valley inversions, especially in areas that are stubborn to mix out, aka Missoula.
Detailed Discussion High pressure over the western Great Lakes has cleared out skies over western MO and eastern KS. Southerly flow is actively pushing warmer temperatures into the region.
346 PM MST Tue Jan 11 2022 High pressure will maintain dry and stable conditions across the region through much of the week.
The longwave upper- level trough has moved off the Eastern Seaboard this morning. Lows tonight will generally be in the low to mid 30s, with upper 30s along the immediate coast.
525 PM CST Tue Jan 11 2022 (Through tonight ) Clear skies and south winds have allowed for warmer temps this afternoon.
632 PM EST Tue Jan 11 2022 High pressure provides dry weather through Wednesday. A high pressure system will slide eastward, allowing for southerly winds tonight into Wednesday.
Issued by National Weather Service Memphis TN 321 PM CST Tue Jan 11 2022 The pattern with an upper ridge over the west and an upper trough over the east will continue to bring a northwest flow over Arkansas through Wednesday. Lows will be in the low to mid 30s through Wednesday.
Temperatures early this afternoon are generally running from the low to upper 60s, similar to or slightly warmer than this time yesterday. This is as a mid/upper level ridge continues to dominate the region's weather pattern while high-level clouds stream inland from the northwest. These clouds are having little impact on the regional temperatures as the warmest interior locations of the Central Coast are once again likely to warm into the lower 70s. Additional warming is anticipated across southern California on Wednesday as the ridge aloft strengthens and temperatures aloft rise. Another mid/upper level low will push into the Pacific Northwest late in the week resulting in a subtle cooling trend across the Bay Area and Central Coast.
Accordingly, have continued with keeping inversion-prone locations cooler than guidance.
High pressure will start to shift east tonight into Wednesday.
Dry and mild weather is expected across the region through the remainder of the week as ensembles indicate ridging remaining in control.
Mostly cloudy to cloudy skies can be expected with low temperatures overnight ranging from the upper 30s to lower 40s well inland to the low to mid 50s at the coast. Sunshine comes back to the area as the day progresses on Wednesday and the system moves on out, and this should allow afternoon temperatures to warm into the low to mid 60s. Quiet weather will prevail for the rest of the short term period (Wednesday night), and expect to have overnight lows maybe a couple degrees cooler than tonight(upper 30s to around 40 well inland to the lower 50s at the coast.
Low temperatures tonight are forecast in the low to mid 30s across most of the area, with the Big Bend and coastal Panhandle in the upper 30s to low 40s.
426 PM MST Tue Jan 11 2022 The afternoon analysis shows the upper ridge rebuilding over the west coast producing northwesterly flow aloft over the northern plains.
810 PM EST Tue Jan 11 2022 A coastal trough is becoming evident over the Treasure Coast to S FL with degradation of the afternoon vertically mixed environment, and a mesoscale rain event is ongoing over S FL south of the local forecast area where flooding is being observed in several locations. Overnight lows will be in the lower 50s inland, mid to upper 50s along the coast, and around 60 near Stuart and Lake Okeechobee. Higher shower coverage is expected to be along the coast and over the Atlantic as a weak inverted trough will also be just to our east, but a few showers are still possible across inland areas.
410 PM EST Tue Jan 11 2022 20Z sfc analysis shows high pressure moving over eastern Kentucky keeping the skies clear and winds light.
626 PM EST Tue Jan 11 2022 High pressure heads toward the coast by tonight.
