137 AM EST Sun Nov 6 2022 A weak cold front will slowly push through the area today and tonight. High pressure then brings dry weather through the middle of the work week. A weak cold front will slowly push through the region today and tonight. Upper level forcing is weak, so models struggling with the placement of precipitation away from the cold front. Skies begin clearing once the aforementioned cold front exits the CWA early Monday.
A potent anticyclone centered to the east of New England stretches southwest across northern Florida. Its upper level counterpart is a narrow but lengthy ridge axis with roots in Central America, and its northern extent reaches into the Canadian Maritimes. Northeast to east breezes will freshen Sunday and Sunday night as a complex area of low pressure develops north of Hispaniola.
A trough in the onshore flow will push west across the FL peninsula Today, spreading the chance for showers across area. High Today will be in the lower 80s.
Temperatures will certainly be the highlight of today's forecast with values likely to near or exceed these records, all set only once and in the specified year: Chattanooga Knoxville Tri-Cities Oak Ridge 81(2015) 79(2005) 79(1938) 82(1948) Tonight Overnight, height rises are expected to continue with lessened downsloping and some advancement of the frontal boundary due to expanding high pressure in the northern U.
A dry cold front has winds across northeast Nebraska more out of the northwest while winds across SE Nebraska and SW Iowa are more out of the southwest. This system is out ahead of a strong upper-level trough moving into the Pacific Northwest.

1009 PM CDT Sat Nov 5 2022 The High Wind Warning that was in effect for the Guadalupe and Delaware Mountains earlier this evening has expired. The forecast remains on track this evening, with lows only expected to drop into the 40s and lower 50s for most, notably warmer than last night, and closer to normal for early November. (This afternoon through Sunday night) Not much going on in the short term in the wake of yesterday's trough. Sunday, flow aloft transitions from northwest to southwest as the next trough begins developing off the west coast. Finally, Sunday night, the LLJ redevelops, advecting lavish Gulf moisture into the region and keeping overnight mins well above normal, despite a cold front backdooring the northeast.
A few patches of fog may also develop as the high clouds clear and the lower clouds either advect into the area or develop. This afternoon, partial to significant clearing will take place, especially over northeast AL as mid and upper level ridging combine to produce subsidence across the area.
(Today and tonight) Wind shift/weak cold front will progress slowly southward over the region today and stall across southeast Oklahoma tonight.
Diurnal mixing potential limited to some degree by inability of daytime heating within a low sun angle to offset a warmer mid level profile, but a general increase in mean thickness and subtle low level warm air advection still supports highs solidly above average. The height fall center will progressively eject to the northeast over the next 24 hours, drawing an attendant cold front through the region tonight. Expansive area of high pressure emanating from an increasingly anticyclonic, high amplitude large scale pattern arrives Monday and holds position just to the north over the next 36 hours.
950 PM CDT Sat Nov 5 2022 (Issued 950 PM CDT Sat Nov 5 2022) Winds have diminished slightly over the past few hours as low pressure over the Upper Peninsula of Michigan continues to move northeast out of the Great Lakes Region. Patterson (Issued 349 PM CDT Sat Nov 5 2022) Tonight and Sunday: Low pressure over southwest Wisconsin this afternoon will lift quickly to Lake Superior by early evening. Strong winds will continue across southern Wisconsin into early evening as the low moves by. Winds will pick up a bit tomorrow morning, as the low level jet moves overhead. High temps tomorrow will be cooler, but still a few degrees above normal for the first week of November.

A weak cold front will slowly push through the region today and tonight. Upper level forcing is weak, so models struggling with the placement of precipitation away from the cold front. Skies begin clearing once the aforementioned cold front exits the CWA early Monday.
A narrow moisture axis ahead of a cold front will arrive this evening, tracking from northwest to southeast. Diurnal mixing potential limited to some degree by inability of daytime heating within a low sun angle to offset a warmer mid level profile, but a general increase in mean thickness and subtle low level warm air advection still supports highs solidly above average.

520 AM CST Sun Nov 6 2022 (Today through Monday afternoon) Will start the day with a flat upper ridge stretching across the country and a strong trough moving onto the NW coast this evening. On Monday this trough will expand east to ID and southward into CA, as it does SW flow will set up over SE NM and W TX. Temperatures will be a little warmer today as readings continue to recover from the recent front.
Bright banding on the radar suggests that snow was melting falling from a mid cloud deck into warmer air below. A cold front will move across the area during the middle of the day. Southwest winds of 10 to 20 mph will make it feel a bit cooler.
550 AM CST Sun Nov 6 2022 (Today through Monday Night ) A large upper trough is over the middle of the country this morning with several upper lows across Canada. An upper ridge builds over the southeast U. A stationary front east of Arkansas will move into the state tonight as a warm front. Lows tonight will be in the upper 40s to lower 60s and in the lower 50s to lower 60s Monday night.
257 AM MST Sun Nov 6 2022 A transitory ridge pulling across the northern Rockies will result in a much calmer day across the forecast area. A warm front lifts northward tonight into Monday morning. and a moist southwest flow develops ahead of an upper low off the Pacific Northwest Coast. East of the Divide, a warm front pulls northward tonight into Monday morning with some overnight lows including Casper occurring early tonight with rising temperatures after midnight. There is a warm nose, so not out of the question for a mixture of light freezing rain/drizzle/snow before the precipitation ends or it turns to rain. Snow will be ongoing across the west Monday night as a trough digging across the West Coast keeps a moist southwesterly flow over the area.
By mid morning, most locations will see a break in the active weather as a low amplitude ridge of high pressure moves over the region.
511 AM CST Sun Nov 6 2022 (Today and tonight) Wind shift/weak cold front will progress slowly southward over the region today and stall across southeast Oklahoma tonight.
Gusty north to northeast winds up to 20-30 mph will turn more easterly overnight with the aforementioned high pressure's movement eastward diminishing with radiational cooling to less than 10-15mph. Sunday afternoon high temperatures into the low to mid 60s under ample sunshine with overnight lows dropping mainly in the 30s, touching the freezing mark for counties to the northwest into west central Kansas.
BB/03 (Now through Monday) An elongated NE to SW upper ridge extending from just off the East Coast to the Yucatan Peninsula will build northwestward and expand over the region as the polar jet associated with the departing trough lifts northward. Meanwhile, we will continue to monitor a stack low pressure area meandering over the southwest Atlantic.
Airmass over our southeastern counties is very moist with dewpoints in the low to mid 60s, so a few showers remain possible into the afternoon.
Dry conditions and slightly above normal temperature return with high pressure for the coming week. Mostly isolated light rain showers will slowly diminish through the evening as they shift east ahead of a decaying sfc cold front. Drying conditions with some cold advection along with clearing skies will lead to cooler, but still seasonably warm, low temperature.
106 PM MST Sun Nov 6 2022 The H5 trough begins to deepen along the West Coast during the next 24 hours, shifting local flow more from the southwest. Have issued Winter Storm Warnings for the higher elevations of the Winds, along with the Tetons, Gros Ventres, and Yellowstone NP, for snowfall accumulations through the next several days. Temperatures at lower elevations of Jackson Hole and Star Valley look to be far enough above freezing on Monday to bring a mix of snow and rain, holding down any snowfall accumulations there through the short term.
Warm frontal showers are also lifting north and will continue for the next several hours. Forecast is on track with sporadic PoPs across north Mississippi and warmer temperatures.
Stacked high pressure remains over the Eastern Seaboard down through FL and into the S Gulf keeping easterly low level flow in place with warm and humid conditions along with scattered fast moving light rain showers this afternoon clearing tonight.
(This evening through Monday) Zonal flow aloft will back to the southwest tonight and through the day Monday as the next upper level trough amplifies over the west coast. Low level moisture will further increase during the day on Monday as surface winds veer to the southeast in response to the aforementioned upper trough near the west coast.
Current radar imagery is picking up on a few weak returns this morning associated with this low-level lift and have increased and extended PoPs for the forecast update this morning. Temperatures are already in the mid to upper 60s with forecast highs in the low to mid 70s.
1126 AM CST Sun Nov 6 2022 (Today through Monday Night ) A large upper trough is over the middle of the country this morning with several upper lows across Canada. An upper ridge builds over the southeast U. A stationary front east of Arkansas will move into the state tonight as a warm front. Lows tonight will be in the upper 40s to lower 60s and in the lower 50s to lower 60s Monday night.
Temps have warmed into the lower to mid 70s, with surface obs showing a much drier airmass in place behind the surface front. As high pressure builds in from the northwest, drier air will continue to filter into the region. Dewpoints will drop into the lower 30s and potentially upper 20s across southern IN and north-central KY and into the 40s across south-central KY. Afternoon highs will be a few degrees cooler in the mid 60s to lower 70s.
1149 AM CST Sun Nov 6 2022 The lowered cloud deck and thick fog are slowly beginning to lift and mix out this morning. A warm and soupy day is on tap with a warm front sliding north through the region.
Tonight looks quiet as the region remains on the southern periphery of low amplitude troughing. High pressure will descend from the northern plains likely pushing the weak front through the area. Heights increase on Monday as a mid-upper level anticyclone pushes north into the Tennessee Valley and Southeast. High pressure at the surface and deep layer subsidence will keep dry and warm conditions across the area. Much colder temps expected this weekend behind a cold front.
Northeast to east winds continue across the island chain and surrounding waters thanks to a large and broad high pressure cell out over the western Atlantic. This is a result of a surface reflection beginning to take shape under a broad upper level trough situated east of the Bahamas and north of Hispaniola and Puerto Rico.
1047 AM CST Sun Nov 6 2022 (Today through Monday afternoon) Will start the day with a flat upper ridge stretching across the country and a strong trough moving onto the NW coast this evening. On Monday this trough will expand east to ID and southward into CA, as it does SW flow will set up over SE NM and W TX. Temperatures will be a little warmer today as readings continue to recover from the recent front.
344 PM EST Sun Nov 6 2022 Dry conditions are expected overnight in the wake of cold front as high pressure noses into the area. A cooler pattern is expected by the start of the workweek before a brief warmup evolves by midweek. Lows tonight to range from the lower 40s northwest to the upper 40s southeast. Mainly clear skies with temperatures ranging from the upper 30s north to the lower 40s south of the Ohio River.
The days 3-7 cluster analysis and glance as the ensembles show the pattern will shift across the CONUS from a trof out west and ridge central and east, to a more predominant northwest flow pattern this weekend.
Mean layer ridging stretches from just off the coast of the Canadian Maritime provinces, southwest into the eastern Gulf of Mexico. This feature is sandwiched between a decaying upper level trough moving into the central Gulf coast and a broad upper level trough/low located over the SW Atlantic/NE Caribbean. Temperatures are gradually climbing and currently sit in the lower to mid 80s with dew points in the lower to mid 70s. As this strengths over the next 24 hours, it in combination with the upper level trough in the central Gulf, will act to fracture the mean layer ridging. Additional SCA will likely be required Monday as a low pressure system will develop north of Hispaniola/ Puerto Rico and move generally westward over the next few days.
Tonight, the LLJ redevelops, advecting profuse Gulf moisture into the area, retarding radiational cooling and keeping overnight lows 5-7F above normal, despite a weak cold front trying to backdoor into the northeast zones. This feature is forecast to make it to about the Pecos River before return flow surges it back north as a warm front.
Temperatures are currently in the upper 70s to lower 80s across the area and highs today should be in the lower to middle 80s for most locations. This activity is progged by the high-res models to persist through the mid-afternoon hours before drying takes place leaving tomorrow night mostly dry.
1005 AM CST Sun Nov 6 2022 The lowered cloud deck and thick fog are slowly beginning to lift and mix out this morning. A warm and soupy day is on tap with a warm front sliding north through the region.
237 PM EST Sun Nov 6 2022 (This afternoon through Monday) High pressure ridge axis at the surface and in the mid levels remain across portions of north and central GA. The ridge at the surface will strengthen as a strong/sprawling high pressure system builds from the north. The boundary should dissipate sometime later tonight or early Monday as the high builds in.
A dynamic low pressure system will skirt northwestern portions of Ontario and Lake Superior overnight. Diurnal mixing potential limited to some degree by inability of daytime heating within a low sun angle to offset a warmer mid level profile, but a general increase in mean thickness and subtle low level warm air advection still supports highs solidly above average. The height fall center will progressively eject to the northeast over the next 24 hours, drawing an attendant cold front through the region tonight. Expansive area of high pressure emanating from an increasingly anticyclonic, high amplitude large scale pattern arrives Monday and holds position just to the north over the next 36 hours.
Latest run of the HREF is showing that heights will rise over the area through tomorrow night as an upper high builds over the southeast CONUS which will keep Missouri and Illinois dry. Latest surface analysis is showing a cold front extending from near Galesburg, Illinois to near Moberly to Sedalia.
1140 AM CST Sun Nov 6 2022 (The rest of today ) Temperatures are 10-20 degrees warmer than this time yesterday across the area thanks to abundant sunshine and a relatively warm start to the day. A frontal boundary was found in the data stretching from northeast Kansas into Texas Panhandle with a prefrontal trough located across southeast Kansas into northern Oklahoma.

1228 PM EST Sun Nov 6 2022 A cold front will sweep southeastward across the area tonight. High pressure will build into the region behind the frontal passage Monday into mid-week. Low pressure will move into the region to end the week. A pleasant and quiet near term forecast period behind the cold frontal passage. A secondary cold front will cross the region southeastward this evening. High pressure over Ontario moves ESE to the New England coast, with surface winds transitioning from northerly to southerly and back to return flow.
A cooler pattern is expected by the start of the workweek before a brief warmup evolves by midweek. Lows tonight range from the lower 40s in west-central OH (and rural/sheltered locales area-wide) to upper 40s in south-central OH/NE KY. Abundant sunshine prevails Monday, with highs ranging from the lower 60s in the N to upper 60s in N KY -- still about 6-8 degrees above seasonal norms.
