311 PM CST Mon Nov 29 2021 Temperatures have overachieved and made it to the 60 degree mark across far southern Minnesota with widespread upper 40s to mid 50s across central Minnesota where a warm front has moved through. This front hasn't quite made it into western Wisconsin where temperatures are still in the low 40s. Winds have already switched back around to the northwest across western Minnesota as of the 2pm hour as the weak cold front on the heels of the aforementioned warm front makes its way eastward. Heading into tomorrow, we'll be a bit cooler with another clipper taking aim at region by tomorrow night. P-type becomes the main concern as temperatures will start out above freezing and then hover near freezing or just above mainly south of I-94.
A continued period of quiet weather is expected through the week with high pressure remaining in control. Dry conditions with temperatures about 10 to 15 degrees warmer than normal can be expected.
Things are quiet across the CWA at this hour with temps ranging from the low 40s across our NE to the upper 40s across our SW. Given the high bases and a very dry low level airmass in place (Tds in the teens), think we'll continue to leave any sprinkle mention out of the forecast.
Temperatures will trend warmer each day with only slightly cooler conditions returning over the weekend. No freezing or sub freezing temperatures are expected.
A cold front will switch winds to the north Tuesday morning. A cold front will push into the forecast area Tuesday shifting the winds to the north and increasing to near 10 to 20 mph or 15 to 25 mph with higher gusts during the afternoon Tuesday. Schneider Gusty north 20 foot winds behind a cold front along with minimum afternoon relative humidity values of near 25 to 30 percent Tuesday may result in wind-driven RFTIs of around 1 to 2 across the western Oklahoma and northwest Texas Panhandles. With the grasses cured across the forecast area, elevated fire weather conditions are anticipated following the passage of the cold front across the western Oklahoma and northwest Texas Panhandles for less than 3 hours Tuesday around 1200 to 1400 hours or so before the winds diminish around mid to late afternoon.
449 PM CST Mon Nov 29 2021 (Through Tonight) Mild and dry overnight with sustained southerly winds ahead of a weak cold front which will move into NE OK Tuesday morning.
318 PM CST Mon Nov 29 2021 Southwest surface flow ahead of an approaching cold front has enabled temperatures to rise to quite unseasonable levels for very late November. Behind this cold front, a small burst of cool air reverts our highs back toward normal, but still unseasonably warm, 50s during the day Tuesday. Model guidance has been holding steady a leeward trough developing that is expected to cruise across OK during the day tomorrow. This high keeps the passing trough to our south creating a small area of convergence along their boundaries.
503 PM CST Mon Nov 29 2021 Tonight a weak cold front will pass through our area.
As this continues southeast conditions become less and less favorable as it become removed from forcing and drier air in the low levels. Temperatures where this is favored to track are above freezing and should hold near or above freezing due to lack of clearing/CAA. A few spots over southeast North Dakota have risen into the lower 50s, while Flag Island on Lake of the Woods is at 28 degrees. Most of the period will be dominated by northwesterly flow aloft thanks to upstream ridging.
553 PM CST Mon Nov 29 2021 Another day of well above normal temperatures with some mid/high clouds overhead across the High Plains. However that will be changing by tonight with short wave energy from the PacNW rounding the top of the western ridge as high pressure at the surface moves into the upper midwest and pushes a weak cold front into Nebraska. Temperature profiles and overnight surface temps in the low/mid 30s will favor rain and although a wet flake or two may be possible up around the Pine Ridge the probability of wintry precipitation is not high enough to mention. Any scattered showers end later Tuesday morning with a brief cool down behind the front, though readings will still remain above normal with highs Tuesday generally in the low/mid 50s.
531 PM CST Mon Nov 29 2021 Southwest surface flow ahead of an approaching cold front has enabled temperatures to rise to quite unseasonable levels for very late November. Behind this cold front, a small burst of cool air reverts our highs back toward normal, but still unseasonably warm, 50s during the day Tuesday. Model guidance has been holding steady a leeward trough developing that is expected to cruise across OK during the day tomorrow. This high keeps the passing trough to our south creating a small area of convergence along their boundaries.
Tonight, temperatures should remain above freezing and with dry air near the surface and temperatures aloft generally above freezing, some sprinkles are probably all we will see from this system. With cloud cover and potentially sprinkles Tuesday, temperatures will be cooler, with temperatures in the 50s.
Elongated high pressure building across the Southeast states will maintain dry conditions, with skies clear and light to calm wind. Overnight lows in the low to mid 40s for much of east-central Florida, except right around 50 degrees for the barrier islands, and low 50s in coastal Martin County. Seas have continued to subside through this evening, with the highest swells at 4-5FT, and closer to 3FT nearshore.
A low pressure system bringing light snow to northeastern Minnesota and northwestern Wisconsin will make a swift exit overnight tonight. Tuesday will be quiet and a little cooler under northwest flow with highs a little closer to normal in the low 30s.
704 PM CST Mon Nov 29 2021 Temperatures have overachieved and made it to the 60 degree mark across far southern Minnesota with widespread upper 40s to mid 50s across central Minnesota where a warm front has moved through. This front hasn't quite made it into western Wisconsin where temperatures are still in the low 40s. Winds have already switched back around to the northwest across western Minnesota as of the 2pm hour as the weak cold front on the heels of the aforementioned warm front makes its way eastward. Heading into tomorrow, we'll be a bit cooler with another clipper taking aim at region by tomorrow night. P-type becomes the main concern as temperatures will start out above freezing and then hover near freezing or just above mainly south of I-94.
432 PM MST Mon Nov 29 2021 Northwesterly flow aloft will continue through the next 36 hours around the high amplitude pattern, with ridging to the west and troughing across the eastern third of the US. The passing of the wave will knock a couple degrees off the record-setting warmth the past several days, but highs will still be in the 50s east of the divide, and the low to mid 40s for western valleys.
402 PM MST Mon Nov 29 2021 00Z TAF CYCLE Weak upper low off Baja CA to circulate some cirrus into srn NM during the next 24 hrs. A couple weak cold fronts will move into eastern NM this week with gusty northeast winds, however temperatures will stay above normal.
Southerly to westerly breezes tonight into Tuesday morning will shift to the north behind a weak cold front Tuesday afternoon. /issued 224 PM CST Mon Nov 29 2021/ Modest upper level ridging overhead this afternoon will give way tomorrow to a weak upper level trough moving in from the northwest. This change will have only minor implications on tomorrow's weather compared to today, mainly the introduction of a weak cold front into the northwestern half of the forecast area. This front will bring slightly cooler temperatures to the northern half of the forecast area, generally 2-5 degrees cooler than today's highs, while south of the front pretty close to status-quo conditions are expected with mild temperatures and relatively light southwest winds persisting. An upper low remains in a blocking pattern over Baja while the FA remains mostly under ridging aloft through late week.
The system is moisture starved in the low levels with only some mid-high level clouds streaming overhead. A weak frontal boundary will also push across the area today with cooler temperatures, however daytime highs will still be above normal.
Still expect lows to bottom out in the lower to middle 30's for most locations, with middle to upper 30's across coastal areas. The light winds and surface wetbulb at or below freezing should still allow for the development of frost, with patchy along the coast and areas of frost inland areas. Lows Tuesday night will be warmer compared to tonight's lows, mainly between 40 to 45 degrees, except along the immediate coast where lows are expected to range from 46 to 52 degrees.
Near the surface, an area of low pressure is located in southeast Colorado. After sunset through tonight, temperatures will remain mild again, above freezing at most locales, in the 30s.
The cold front is expected to move across the area tomorrow morning while a broad trough moves southeast across the Plains during the day. An area of high pressure at the surface will move east over the Tri-State area.
1155 PM CST Mon Nov 29 2021 Southwest surface flow ahead of an approaching cold front has enabled temperatures to rise to quite unseasonable levels for very late November. Behind this cold front, a small burst of cool air reverts our highs back toward normal, but still unseasonably warm, 50s during the day Tuesday. Model guidance has been holding steady a leeward trough developing that is expected to cruise across OK during the day tomorrow. This high keeps the passing trough to our south creating a small area of convergence along their boundaries.
Early morning surface map indicated a clipper low over southern Lake Michigan with a cold front extending southwest and bisecting the CWA. Aloft, upper air data showed northwest flow firmly entrenched across the Midwest, between a ridge off the CA coast and a trof off the New England coast.
1213 AM EST Tue Nov 30 2021 [Through 06Z Wednesday] High pressure will dominate across the TAF sites today allowing for light winds. As a cool, dry airmass builds into the area tonight with high pressure, the main concern will be the potential for another round of frost and freeze conditions. Reality usually verifies on the cold side of guidance in these situations for low temperatures, particularly across the Florida big bend, so the official forecast is in the low end of the guidance suite for tonight. For Tuesday, high pressure will continue across the area with sunny skies. High pressure will be settling over the Southeast US. Radiational cooling will allow for cooler nights with Low temperatures in the upper 30s and low 40s.
233 AM CST Tue Nov 30 2021 Key Points: - Cooler, yet above average temps persist through the work week. Added scattered sprinkles for the day given the lower stratus observed upstream.
920 PM MST Mon Nov 29 2021 Northwesterly flow aloft will continue through the next 36 hours around the high amplitude pattern, with ridging to the west and troughing across the eastern third of the US. The passing of the wave will knock a couple degrees off the record-setting warmth the past several days, but highs will still be in the 50s east of the divide, and the low to mid 40s for western valleys.
At the surface, a low pressure system will track across the Great Lakes and New England today, with an E-W elongated high near the Gulf coast. This will produce a low level SW flow today that will bring warmer temperatures and higher dewpoints.
256 AM EST Tue Nov 30 2021 Weak low pressure was analyzed over southern Lake Michigan early this morning. Conditions are notably breezy in the lower levels ahead of a cool front draped through Illinois and Missouri. SW to W low-level flow is pumping warmer air into the region, and temperatures are significantly warmer than 24 hours ago. Upper 30s to mid 40s are common, with just a couple lingering spots in the east in the lower 30s. An approaching wave of low pressure will bring widespread mid-level clouds to the region early Wednesday. Flow aloft over our region will remain out of the northwest through the end of the week, but a strong ridge over the southern Plains will slowly nudge toward the region.
307 AM EST Tue Nov 30 2021 High pressure will nose into the Ohio Valley today leading to dry conditions through tonight. High pressure builds in from the south overnight. Fairly clear skies and calming winds early overnight under the high will allow temperatures to quickly drop into the 30s.
High pressure continues to drift eastward, but calm winds and a dry air mass lingering over us will allow for good radiational cooling again. Increasing southerly flow across northeast Louisiana and through the Delta around the fringes of the high will keep temperatures a few degrees warmer in those areas tonight. Where winds are light and temps fall into the lower 30s, some frost is possible. Prior discussion below: Tonight and Tuesday: High pressure at the surface will slide east of the region overnight into Tuesday as flow aloft begins to subtly flatten. Therefore, under mostly clear skies tonight, lows will be chilly and range from the mid 30s to the lower 40s.
Weakening cold front clips the northeast Nevada corner. Slightly cooler air mass follows the aforementioned cold front, so not as warm Tuesday afternoon. High pressure reasserts itself on Wednesday, but some Pacific moisture spills over the northern Nevada Tuesday night and Wednesday morning for scattered altocumulus (but no rain or snow). Near record highs across the central Nevada valleys that reaching the lower 60s.
High pressure centered across Alabama this morning will slide eastward and dominate the weather through the near term. Temperatures are near freezing this morning and expected to drop below freezing at many locations over the next few hours. As low level winds become more east to southeast overnight, lows tomorrow morning will be slightly warmer (although still cold) with lows in the mid 30s to lower 40s. Forecast lows for tonight are generally on the cooler side of guidance.
Temperatures have overachieved and made it to the 60 degree mark across far southern Minnesota with widespread upper 40s to mid 50s across central Minnesota where a warm front has moved through. This front hasn't quite made it into western Wisconsin where temperatures are still in the low 40s. Winds have already switched back around to the northwest across western Minnesota as of the 2pm hour as the weak cold front on the heels of the aforementioned warm front makes its way eastward. Heading into tomorrow, we'll be a bit cooler with another clipper taking aim at region by tomorrow night. P-type becomes the main concern as temperatures will start out above freezing and then hover near freezing or just above mainly south of I-94.
1013 PM MST Mon Nov 29 2021 06Z TAF CYCLE Weak upper low off Baja CA to circulate some cirrus into srn NM during the next 24 hrs. A couple weak cold fronts will move into eastern NM this week with gusty northeast winds, however temperatures will stay above normal.
1105 PM CST Mon Nov 29 2021 Another day of well above normal temperatures with some mid/high clouds overhead across the High Plains. However that will be changing by tonight with short wave energy from the PacNW rounding the top of the western ridge as high pressure at the surface moves into the upper midwest and pushes a weak cold front into Nebraska. Temperature profiles and overnight surface temps in the low/mid 30s will favor rain and although a wet flake or two may be possible up around the Pine Ridge the probability of wintry precipitation is not high enough to mention. Any scattered showers end later Tuesday morning with a brief cool down behind the front, though readings will still remain above normal with highs Tuesday generally in the low/mid 50s.
A low pressure system bringing light snow to northeastern Minnesota and northwestern Wisconsin will make a swift exit overnight tonight. Tuesday will be quiet and a little cooler under northwest flow with highs a little closer to normal in the low 30s. Due to advection of dry air aloft into the system, some slight chances for freezing rain among the snow showers is possible, but the main form of precipitation should be snow. A mixed bag tonight as an area of low pressure pulls away and low stratus replaces it.
929 PM CST Mon Nov 29 2021 (Issued 929 PM CST Mon Nov 29 2021) Low pressure over south central WI will move to Lake Erie by 12Z Tue. Modest nwly winds will develop after the passage of the low this evening with initial warming of temps where radiational cooling was occurring. Sunshine on Tue will help boost temps into the lower to middle 40s for the afternoon. Low level CAA will be gradual on Tuesday with surface ridging drawing closer to the area towards evening.
Temperatures are falling on course as predicted, looking to reach lows in the low to mid 40s areawide by daybreak.
A weak cold front will continue to move south through the forecast area tonight owing to the trough that is currently grazing northeast Utah and southwest Wyoming. Some low clouds exist just north of the Bear Lake area in conjunction with this trough, just a few of which are expected to make it into Utah. A strong area of high pressure remains parked over the eastern Great Basin this afternoon with little to no change expected going through the next 48 hours.
/issued 850 PM CST Mon Nov 29 2021/ High pressure remains over the Tennessee River Valley this evening. Temperatures will trend warmer each day with only slightly cooler conditions returning over the weekend. No freezing or sub freezing temperatures are expected.
251 AM CST Tue Nov 30 2021 A positively tilted upper level short wave moving southeast through Colorado and eventually through the northern Panhandles this afternoon will help to drive a cold front through the area. Winds will get up into the 20 to 30 mph range with higher gusts behind the cold front, especially across the western Panhandles.
Models have come much more in line for an expected weak upper level trough that will move through south central Indiana during the daytime hours on Wednesday.
With warmer air aloft advecting in precipitation type will transition to rain west to east across the forecast after 06z Wednesday. 00z GFS/NAM bufkit soundings suggest loss of ice in cloud and areas across central/north central Wisconsin could see a brief period of freezing rain 10z to 13z Wednesday.
High pressure centered over the southeastern US will allow for gradual warming temperatures and increasing low level moisture as southerly to southwesterly winds prevail over the next few days. Highs in the low 80s are likely in some locations, especially along and west of the I-35 corridor, which is roughly 15-20 degrees above-normal for early December.
1138 PM CST Mon Nov 29 2021 Another day of well above normal temperatures with some mid/high clouds overhead across the High Plains. However that will be changing by tonight with short wave energy from the PacNW rounding the top of the western ridge as high pressure at the surface moves into the upper midwest and pushes a weak cold front into Nebraska. Temperature profiles and overnight surface temps in the low/mid 30s will favor rain and although a wet flake or two may be possible up around the Pine Ridge the probability of wintry precipitation is not high enough to mention. Any scattered showers end later Tuesday morning with a brief cool down behind the front, though readings will still remain above normal with highs Tuesday generally in the low/mid 50s.
Conditions are expected to remain this way overnight with morning temperatures dropping into the low to mid 40s, save for the possibility of early morning fog that could form as we continue cooling off overnight.
A weak cold front will move into the Texas Panhandle this morning, slowly move south and arrive in the Permian Basin this evening and tonight. In fact, high temps tomorrow will be similar to today and in some places may even be slightly warmer.
1228 AM EST Tue Nov 30 2021 A weak low pressure system over the upper Mississippi valley to track quickly through the Great Lakes tonight. High pressure and a drier airmass will settle into the area for Tuesday. In the warm air advection ahead of this low, favorable isentropic lift has lead to an axis of snow showers pivoting thru ILN/s n/ne counties. Temperatures will fall to lows in the lower and middle 30s overnight. Highs on Tuesday will range from the mid 40s north to the lower 50s in the south with lows Tuesday night in the upper 20s to lower 30s.
1036 PM EST Mon Nov 29 2021 A weak low pressure system over the upper Mississippi valley to track quickly through the Great Lakes tonight. High pressure and a drier airmass will settle into the area for Tuesday. In the warm air advection ahead of this low, favorable isentropic lift has lead to an axis of snow showers pivoting thru ILN/s n/ne counties. Temperatures will fall to lows in the lower and middle 30s overnight. Highs on Tuesday will range from the mid 40s north to the lower 50s in the south with lows Tuesday night in the upper 20s to lower 30s.
Upper ridge is located over the southwest CONUS. Highs today will be a bit cooler in wake of cold front, with highs mainly in the 50s (40s in the Black Hills).
/issued 709 PM EST Mon Nov 29 2021/ High pressure has built in over the southeast U.
Another cold morning Tuesday with lows in the lower 30s to upper 20s. Rebounding highs mostly in the lower 60s Tuesday and warmer lows Wednesday in the middle to upper 30s.
Dry and warmer Tuesday courtesy of high pressure. High pressure will gradually start to build into the region behind the departing wave, with dry conditions. Slightly warmer as compared to recent days with a southwesterly to westerly flow taking hold.
1130 PM CST Mon Nov 29 2021 Expect mostly clear skies with lows in the lower 30s tonight.
High pressure building in over the area today will support cool dry weather across the entire forecast area. Tonight and through the remainder of the week dry weather will continue as high pressure slowly shifts east into the Atlantic and extends back to the west across the north central peninsula with the low level northeast flow today veering slowly to the east through the remainder of the week.
Things are quiet across the CWA at this hour with temps ranging from the low 40s across our NE to the upper 40s across our SW. Given the high bases and a very dry low level airmass in place (Tds in the teens), think we'll continue to leave any sprinkle mention out of the forecast. Variable cloudiness will make nailing this temp forecast difficult, but a general range in the low to mid 50s for most is reasonable.
945 PM CST Mon Nov 29 2021 Tonight a weak cold front will pass through our area. An upper level ridge moving toward us will aid in keeping temperatures unseasonably warm for the rest of the week.
30/06Z TAF CYCLE An expansive area of high pressure parked over the region will bring widespread VFR conditions to the terminals through the period.
Temperatures have already dropped down into the low to mid 30s as of the most recent obs. Low level westerly winds are expected to continue during the day on Tuesday, as high pressure remains over the area. This should force low level winds to become southwesterly and advect even warmer and more moist air into the area. However, high pressure should remain in control of the area, keeping the airmass over northern Alabama and southern middle Tennessee too dry for much cloud cover or any precipitation as the weak front (associated with the clipper system exiting the Great Lakes region) pushes southeast into the area Wednesday afternoon. Highs on Tuesday should climb into the lower to mid 60s with lows only dropping into the upper 30s to lower 40s.
(Today and tonight) A weak cold front will slowly move south across northern Oklahoma today before stalling. The airmass behind the front is still quite mild for late November, but it will knock down the high temperatures across northern Oklahoma compared to yesterday. Temperatures across southern Oklahoma and north Texas will be similar or slightly warmer than yesterday.
