(This evening through Tuesday) The warm front currently located across southeast Oklahoma into north Texas will continue to lift northward overnight, with associated warm advection leading to increasing precipitation chances for much of the area.
BB/03 (Now through Tuesday) An elongated SW to NE upper ridge extending from Northeast Mexico the Mid-Atlantic States will build northward and expand over much of the eastern CONUS through Tuesday afternoon.
1040 AM CST Mon Nov 7 2022 A frontal boundary is stalled across our CWA as of 16Z, leading to a stark temperature gradient from northeast Arkansas in the mid 50s to northeast Mississippi in the low 70s.
Otherwise, it's an unusually warm and muggy day with temperatures well into the 70s and dewpoints ranging from the low 50s in our northwest to the upper 60s in our south.
(The rest of today ) Warm front remains near the Red River this morning, with gradually expanding low cloud cover through southeast/east central OK and much of western AR.
Current readings across the Keys range from the lower to mid 80s. Dew points are somewhat comfortably in the lower 70s.
1008 AM CST Mon Nov 7 2022 (Today through Tuesday afternoon) Cooler temperatures are in store today as a back-door cold front is currently sagging south across the region. This should keep temperatures much cooler than yesterday across these areas. Continued moisture advection tonight keeps temperatures from cooling much at all across the lower elevations. Strong southerly winds develop tomorrow and help push temperatures several degrees warmer, but skies remain cloudy with rich moisture remaining in place.
1158 AM CST Mon Nov 7 2022 (Today through Tuesday Night ) Southwest flow aloft is over much of the country with upper lows in the Pacific Northwest and just north of the Great Lakes. High pressure will build over the southeast U. Tuesday, the western trough moves south along the west coast and the upper ridge strengthens over the eastern half of the country. The rain is a result of a warm front that has entered the state from the south. Also a weak cold front entered the state from the north. Lows tonight and Tuesday night will be in the lower 50s to lower 60s.
A deep upper level trough over the west coast will begin to move inland which will be the cause of this low level moisture influx.
1222 PM EST Mon Nov 7 2022 Dry, pleasant weather will prevail through much of the week with high pressure in place.
1144 AM CST Mon Nov 7 2022 (Today through Tuesday afternoon) Cooler temperatures are in store today as a back-door cold front is currently sagging south across the region. This should keep temperatures much cooler than yesterday across these areas. Continued moisture advection tonight keeps temperatures from cooling much at all across the lower elevations. Strong southerly winds develop tomorrow and help push temperatures several degrees warmer, but skies remain cloudy with rich moisture remaining in place.
1032 AM EST Mon Nov 7 2022 Dry, pleasant weather will prevail through much of the week with high pressure in place.
1207 PM CST Mon Nov 7 2022 A frontal boundary is stalled across our CWA as of 16Z, leading to a stark temperature gradient from northeast Arkansas in the mid 50s to northeast Mississippi in the low 70s.
Dew points this afternoon have already fallen into the low/mid 40s for most of central KY. Seasonal overnight lows are likely across central KY and southern IN with temperatures falling into the low 40s/upper 30s across the north-central KY, southern IN and the Bluegrass while lows will be in the mid/upper 40s to near 50 across south-central KY. Temperatures will be cooler than today but still above normal ranging from the low/mid 60s across the Bluegrass, southern IN and north-central KY with highs near 70 closer to the KY/TN border.
(This evening through Tuesday) As a weak cold front further dissipates, isolated showers and thunderstorms are possible tonight, mainly across eastern portions. With low level moisture over the region and return of low clouds, temperatures will be mild, with lows in the lower 60s.
Current temperatures are in the low to mid 70s this morning with dewpoints in the upper 60s to low 70s. The strength of the upper ridge is more typical of a late summer ridge with 500 mb heights around 590 dm.
1129 AM CST Mon Nov 7 2022 (The rest of today ) Warm front remains near the Red River this morning, with gradually expanding low cloud cover through southeast/east central OK and much of western AR.
A few showers continue to linger in extreme south portions of mainly western KY, but any pcpn is expected to diminish by this evening as drier air filters in through the low levels with northeast flow. Nighttime lows will range from the mid 40s to low 50s as thicker cloud cover will keep our southern counties a bit warmer. The reminder of the period will be dominated by a mid to upper level ridge of high pressure that will be centered over the lower Ohio Valley.
(This afternoon through Tuesday) Deep ridging is centered directly over Central Alabama, and the transient stalled surface front is still extended east to west across Tennessee. Surface convergence fades tomorrow as the front erodes with the low-level ridging building east and setting up a more prominent northeasterly flow. This will begin to provide a cooler, drier airmass to the region with dewpoints falling into the 50s across our east. Highs will still reach the lower to mid 80s for most areas, but begin trending cooler by midweek.
Overnight lows dip into the lower 40s in the city, with lower to mid 30s expected in the outer suburbs and rural areas. Tuesday high temperatures will be slightly warmer than today by a couple degrees as the surface flow turns more southeasterly and the upper ridge begins to amplify overhead and across the eastern CONUS and Canada.
The southeastern TX Panhandle has the higher chances for rain showers, as this area will have a little more moisture throughout the column.
With lows falling only into the low-mid 60s areawide, crossover temps are expected to be 4-6 degrees.
Clouds will gradually scatter out through the afternoon with high temperatures climbing into the upper 70s to mid 80s under an expanding upper-level ridge.
High pressure over the Great Lakes and upper ridging will remain the primary features, with mid to high level clouds streaming into the Ohio Valley through the overnight hours. However, model soundings in that area suggest enough dry air in the lower levels to believe it's primarily virga. Dew points this afternoon have already fallen into the low/mid 40s for most of central KY. Seasonal overnight lows are likely across central KY and southern IN with temperatures falling into the low 40s/upper 30s across the north-central KY, southern IN and the Bluegrass while lows will be in the mid/upper 40s to near 50 across south-central KY. Temperatures will be cooler than today but still above normal ranging from the low/mid 60s across the Bluegrass, southern IN and north-central KY with highs near 70 closer to the KY/TN border.
A large trough, currently off the Pacific Northwest coast, will move southward before moving onshore Tuesday afternoon and progressing eastward Tuesday night.
531 PM CST Mon Nov 7 2022 (This evening through Tuesday) As a weak cold front further dissipates, isolated showers and thunderstorms are possible tonight, mainly across eastern portions. With low level moisture over the region and return of low clouds, temperatures will be mild, with lows in the lower 60s.
Temperatures this evening range from the lower 60s to lower 70s.
506 PM CST Mon Nov 7 2022 (This evening through Tuesday) The warm front currently located across southeast Oklahoma into north Texas will continue to lift northward overnight, with associated warm advection leading to increasing precipitation chances for much of the area.
713 PM EST Mon Nov 7 2022 Drier weather through midweek as a backdoor front pushes through the region on Tuesday, bringing cooler weather.
553 PM CST Mon Nov 7 2022 (This afternoon through Tuesday) Deep ridging is centered directly over Central Alabama, and the transient stalled surface front is still extended east to west across Tennessee. Surface convergence fades tomorrow as the front erodes with the low-level ridging building east and setting up a more prominent northeasterly flow. This will begin to provide a cooler, drier airmass to the region with dewpoints falling into the 50s across our east. Highs will still reach the lower to mid 80s for most areas, but begin trending cooler by midweek.
A large trough, currently off the Pacific Northwest coast, will move southward before moving onshore Tuedsay afternoon and progressing eastward Tuesday night.
These showers are mostly out over the surrounding waters but have on occasion moved over the Lower Keys. This surge in winds is being driven by a tightening of the pressure gradient between Subtropical Storm Nicole as it slowly moves northwest towards the Bahamas and a strong ridge over the western North Atlantic.
649 PM EST Mon Nov 7 2022 Dry, pleasant weather will prevail through much of the week with high pressure in place.
Otherwise, cold will settle into the area with lows dipping into the single digits and teens and highs staying at or below freezing through the at least through workweek. These snow showers were particularly problematic as they produced localized amounts up to an inch quickly as air and road temperatures fell below freezing.
327 AM EST Tue Nov 8 2022 Present surface analysis has a strong high pressure centered to the north of the forecast area. This pressure center will continue to favor warmer and drier weather through the entire short-term period. As the high continues to remain to the N/NE, anticyclonic flow will keep the area under E/NE winds through the day today. Also, with the lowered dewpoints, increased fire danger exists for today. Tonight will provide a challenge as clear skies are likely to exist and decoupling valleys could create a complicated ridge-valley split forecast. Presently leaned toward a slight warmer trend and blend with the previous forecaster for the eastern valley temperatures.
1258 AM EST Tue Nov 8 2022 Drier weather through midweek as a backdoor front pushes through the region today, bringing cooler weather.
(Today) A typical summertime morning is underway across the Tennessee Valley with morning lows in the lower 60s. The Southeast sits under a 590 dm 500 mb high pressure system.
Warmer than normal temperatures and humidity will continue tonight. With lows falling only into the low-mid 60s areawide, crossover temps are expected to be 4-6 degrees.
A cold front will continue to stall over portions of southern Idaho this evening into Tuesday morning, creating a swath of snow and MVFR/IFR conditions.
A 591 dm 500-mb ridge is centered over the Southeast US, southeast of a giant trough over the Pacific Northwest. Heights are still rising underneath the ridge.
344 AM EST Tue Nov 8 2022 Dry, pleasant weather will prevail through much of the week with high pressure in place.
(Today and tonight) An upper level ridge will remain centered across the Southeast United States today. The position of the ridge has allowed for a return of moisture to West Central Texas, with dewpoints in the 60s. Dewpoints in the 60s along with increasing cloud cover will result in overnight lows in the low to mid 60s, well above seasonal normals.
1053 PM CST Mon Nov 7 2022 (This evening through Tuesday) As a weak cold front further dissipates, isolated showers and thunderstorms are possible tonight, mainly across eastern portions. With low level moisture over the region and return of low clouds, temperatures will be mild, with lows in the lower 60s.
302 AM EST Tue Nov 8 2022 Stacked ridging will continue to prevail over central Indiana today. Forecast soundings continue to show a very dry column, with a few higher clouds spinning into the region from the southwest around the upper ridge. Ridging will continue over Indiana tonight, as the pattern begins to transition to a stronger moderating trend. Lows in the low 40s will be the rule. However, models have been trending a bit cooler, so temperatures won't likely be close to record values.
1037 PM EST Mon Nov 7 2022 Drier weather through midweek as a backdoor front pushes through the region on Tuesday, bringing cooler weather.
119 AM EST Tue Nov 8 2022 Dry, pleasant weather will prevail through much of the week with high pressure in place.
Where we shifted it west, the forecast has the potential of adding another inch or two for places like Mackay and the higher elevations of the surrounding mountains.
251 AM EST Tue Nov 8 2022 High pressure will continue to be in place across the region through mid-week.
1056 PM CST Mon Nov 7 2022 (This evening through Tuesday) The warm front currently located across southeast Oklahoma into north Texas will continue to lift northward overnight, with associated warm advection leading to increasing precipitation chances for much of the area.
08 Previous short-term discussion: (This afternoon through Tuesday) Deep ridging is centered directly over Central Alabama, and the transient stalled surface front is still extended east to west across Tennessee. Surface convergence fades tomorrow as the front erodes with the low-level ridging building east and setting up a more prominent northeasterly flow. This will begin to provide a cooler, drier airmass to the region with dewpoints falling into the 50s across our east. Highs will still reach the lower to mid 80s for most areas, but begin trending cooler by midweek.
(Today through Wednesday) One more warm day on tap for today, before a backdoor cold front works in from the east late this afternoon into the evening. This front will usher in cooler and drier air for Wednesday along with fairly clear skies, at least through the morning. As the front works east, the cooler air will drop temperatures into the upper 40s/low 50s in the east.
Another round of snow is expected on Wednesday, before drier and slightly warmer air moves back in over the weekend. This third round of snow will develop as the closed upper low tracks from northern California across the intermountain west.
Model guidance agrees that a low pressure center will approach the region tonight. Despite the uncertainty in the mid level low track, confidence is high that a broad area of snow will associate with the low, and the HREF ensemble mean shows Lake County and southern Flathead County being the northern extent of the snow.
A second, stronger push of snow will occur on Wednesday, when around 3 inches of snow is expected for the advisory area as the upper low moves across the region.
441 AM MST Tue Nov 8 2022 09z surface analysis had cold front from far western ND to central WY, oozing southeast per 1-2mb/3hr pressure rises behind it. Water vapour loop had strong trough sliding into the northwest CONUS with southwest flow aloft over the CWA. Main forecast concern is disposition of upper trough: - Sharp temperature gradient today.
Even though PBL will mix to around 8h by 21Z high temps will mostly be bound in the 70s, except 80s Upper Trans Pecos and some 90s in/around the lowest elevations of Rio Grande. Drier air will have a chance to mix into far wrn CWFA Wed PM, if low-level thermal ridge can amplify.
236 AM MST Tue Nov 8 2022 09z surface analysis had cold front from far western ND to central WY, oozing southeast per 1-2mb/3hr pressure rises behind it. Water vapour loop had strong trough sliding into the northwest CONUS with southwest flow aloft over the CWA. Main forecast concern is disposition of upper trough: - Sharp temperature gradient today.
All the low clouds should mix out late in the day, setting up clear skies over southeast Michigan this evening and tonight with very light easterly winds. Slowly exiting surface ridging tucked beneath larger scale anticyclonic flow held within the resident higher amplitude upper ridge will mark conditions today. Otherwise, subtle boundary layer cooling as the easterly gradient takes an increasing hold lending to slightly cooler late day highs relative to yesterday.
Southwesterly flow aloft will increase throughout the day as mid-level trough moves into the Desert Southwest. Low temperatures will be a bit warmer, as radiation cooling will be limited from the cloud cover.
A deep upper low currently situated along the PNW coast will continue to bring winter weather to the region for the next few days. A warm front and the next round of precipitation will work into the region from the south this evening, bringing snow levels to around 6000 feet and higher from the lower Snake Plain southward. 8 to 12 inches will fall above 6500 feet along the Lost River Range, Beaverhead-Lemhi Highlands, and Island Park area, with the highest peaks of the Centennial Mountains receiving up to 14 inches.
531 AM CST Tue Nov 8 2022 (Today through Wednesday) One more warm day on tap for today, before a backdoor cold front works in from the east late this afternoon into the evening. This front will usher in cooler and drier air for Wednesday along with fairly clear skies, at least through the morning. As the front works east, the cooler air will drop temperatures into the upper 40s/low 50s in the east.
805 AM EST Tue Nov 8 2022 Nicole continues to organize over the southwest Atlantic Ocean with a tight pressure gradient setting up between it and high pressure well to the north over southern Canada.
Recent model runs have favored a quicker pass of the cold front associated with this storm system.
Present surface analysis has a strong high pressure centered to the north of the forecast area. This pressure center will continue to favor warmer and drier weather through the entire short-term period. As the high continues to remain to the N/NE, anticyclonic flow will keep the area under E/NE winds through the day today. Also, with the lowered dewpoints, increased fire danger exists for today. Tonight will provide a challenge as clear skies are likely to exist and decoupling valleys could create a complicated ridge-valley split forecast. Presently leaned toward a slight warmer trend and blend with the previous forecaster for the eastern valley temperatures.
502 AM CST Tue Nov 8 2022 (Today and tonight) An upper level ridge will remain centered across the Southeast United States today. The position of the ridge has allowed for a return of moisture to West Central Texas, with dewpoints in the 60s. Dewpoints in the 60s along with increasing cloud cover will result in overnight lows in the low to mid 60s, well above seasonal normals.
701 AM EST Tue Nov 8 2022 Dry, pleasant weather will prevail through much of the week with high pressure in place.
506 AM EST Tue Nov 8 2022 Dry, pleasant weather will prevail through much of the week with high pressure in place.
High pressure at the surface and aloft will continue the pleasant conditions with ample sunshine expected and highs rising into the upper 50s to mid 60s today, which is in line with current forecast as well as latest high resolution numerical guidance. Stacked ridging will continue to prevail over central Indiana today. Forecast soundings continue to show a very dry column, with a few higher clouds spinning into the region from the southwest around the upper ridge. Ridging will continue over Indiana tonight, as the pattern begins to transition to a stronger moderating trend. Lows in the low 40s will be the rule. However, models have been trending a bit cooler, so temperatures won't likely be close to record values.
541 AM CST Tue Nov 8 2022 (Today through Wednesday Night ) An upper ridge is located over northern Mississippi with an upper low over the Pacific Northwest. An upper low associated with Nicole in the Atlantic will move west towards Florida today as the high builds over the southeast U. The latest KLZK sounding shows a strong low level inversion and as a result the low clouds will continue much of the day. High pressure will continue over the area Wednesday. Expect warmer temperatures today with highs in the upper 60s to lower 80s and Wednesday highs will be in the mid 70s to lower 80s. Lows tonight and Wednesday night will be in the lower 50s to lower 60s.
504 AM CST Tue Nov 8 2022 (Today) A typical summertime morning is underway across the Tennessee Valley with morning lows in the lower 60s. The Southeast sits under a 590 dm 500 mb high pressure system.
Upper ridging remains extended across the region through Wednesday while at the surface, a back door front will work southwestward across the forecast area today. The cooler temperatures will become apparent overnight with low temperatures returning to the 40s--close to seasonal norms.
Otherwise, the anomalous subtropical ridge axis will remain fixed over the forecast area, and this will result in another day of near record warmth under mostly sunny skies.
Stacked ridging will continue to prevail over central Indiana today. Forecast soundings continue to show a very dry column, with a few higher clouds spinning into the region from the southwest around the upper ridge. Ridging will continue over Indiana tonight, as the pattern begins to transition to a stronger moderating trend. Lows in the low 40s will be the rule. However, models have been trending a bit cooler, so temperatures won't likely be close to record values.
A ridge will build along the coast and bring a north to south flow pattern of cold, dry air into the region with breezy winds through the northern valleys. Today and Wednesday: A Low pressure center continues to slide south along the coast and dry, cool air is filling in behind it.
High pressure aloft sits centered nearly directly over the forecast area today. At the same time, high pressure at the surface, centered over the New England states and Southeast Canada, will remain wedged into the forecast area. Otherwise, the anomalous subtropical ridge axis will remain fixed over the forecast area, and this will result in another day of near record warmth under mostly sunny skies.
Mid/high level cloud cover also covers parts of the region, despite the fact a fairly strong upper ridge axis extends from SE TX NW into the central Gulf states.
A low pressure system tonight will expand snow south to north through Wednesday morning. Model guidance agrees that a low pressure center will approach the region tonight. Despite the uncertainty in the mid level low track, confidence is high that a broad area of snow will associate with the low, and the HREF ensemble mean shows Lake County and southern Flathead County being the northern extent of the snow.
242 PM EST Tue Nov 8 2022 Very strong (~1044mb) high pressure over Ontario is influencing the weather over much of the eastern CONUS today. Anticyclonic flow around the high has resulted in northeasterly to easterly flow across our region and has also contributed to a broad temperature/dewpoint gradient across southern Indiana and central Kentucky. Lows tomorrow morning will likely be in the low to mid 40s for many locations, but sheltered valleys could drop into the 30s where winds go calm. This will result in an influx of warmer temperatures advecting in from the south resulting in high temps about 5-10 degrees warmer for Wednesday (11/9) compared to Tuesday (11/8).
118 PM EST Tue Nov 8 2022 Dry, pleasant weather will prevail through much of the week with high pressure in place.
Discussion: Calm and pleasant conditons anticipated for the remainder of Tuesday and Wednesday as high pressure and ridging remain in control of the story. While Wednesday will be slightly cooler than recent days, forecast highs are still above normal.
(This afternoon through Wednesday) Another warm afternoon is underway across Central AL with a dominant ridge stationed over the eastern CONUS. East-northeasterly flow from the low to mid levels will eventually push out this warmer airmass tonight, but before then, temperatures around the mid 80s will match or threaten a few more records again this afternoon. Cooler air arrives to the area tonight as a backdoor cold front advects southwest along the spine of the Appalachians. The ridge begins to work its way towards the western Atlantic tomorrow, but remains extended across the Southeast providing us with comfortable temperatures closer to seasonal averages.
