Short Term Update - Ridging will continue to dominate through the overnight period. A ridge along the Gulf and Atlantic coast will maintain a modest north to northeast flow.
346 AM EST Tue Nov 7 2023 High pressure will extend across the region this week.
1056 PM CST Mon Nov 6 2023 (Tonight) As high pressure continues to linger to our east, southerly flow allows warm air to be advected into the TN Valley.
(Tonight through Tuesday) Some of the normally cooler locations and areas near water bodies may see some ground fog develop early on Tuesday morning. An upper level ridge is centered over the central Gulf of Mexico and will begin to amplify over the next few days. Drought conditions will continue to worsen as highs reach the lower 80s areawide.
1207 AM EST Tue Nov 7 2023 (This afternoon through Tuesday) High pressure will continue to move slowly eastward from the Gulf of Mexico into the Florida Peninsula. Lows tonight will be in the lower to mid 60s over most areas, except around 70 east coast metro areas. Highs on Tuesday will be a little bit warmer due to the northeast wind flow with mid to upper 80s over most areas, except mid 80s east coast metro areas.
1006 PM EST Mon Nov 6 2023 Unseasonably warm temperatures will continue through midweek with plenty of sunshine as high pressure dominates over the Southeast.
1223 AM EST Tue Nov 7 2023 Winds will diminish and temperatures will trend slightly cooler behind a cold front tonight into tomorrow.
Highs this afternoon look to climb mainly into the lower 80s/near 80F, which is around 10-15F above normal for this time of the yr.
1157 PM EST Mon Nov 6 2023 Low pressure exiting the Great Lakes into Quebec is pulling a primary cold front into central Lower Mi leading up to midnight. Late evening clear sky lasts until exiting low pressure pulls the primary cold front through SE Mi late tonight. -Cooler on Tuesday with daytime temperatures approximately 5 degrees below normal.
944 PM CST Mon Nov 6 2023 (Issued 942 PM CST Mon Nov 6 2023) The cooler air is on its way along with northerly wind shift and cloud cover tonight. Otherwise, previous forecast remains on track with cooler high temps for Tuesday. Wagner (Issued 255 PM CST Mon Nov 6 2023) Tonight and Tuesday: A weak ridge of high pressure will briefly build into the region tonight and Tuesday. Gagan (Issued 255 PM CST Mon Nov 6 2023) Tuesday night through Monday: Isentropic upglide kicks into gear late Tuesday night as low pressure gains strength in the central Plains.
400 AM EST Tue Nov 7 2023 A crossing cold front will bring mainly clouds, breezy conditions and slightly cooler temperatures today.
A mild night is ahead for the area with warm, southerly winds and streaming high clouds helping to keep overnight lows warmer compared to the previous few nights.
Quasi-zonal flow continues across the CONUS with a strong U/L ridge over the Gulf of Mexico and Florida. today with a positively tilted trough digging over the inter-mountain west. This will aid in pumping up the downstream ridge over the Gulf of Mexico and Florida with building heights and strong large scale subsidence developing over the region. A series of northern stream disturbances will push across the country this week with a broad L/W trough developing over the eastern U. during the upcoming weekend with broad ridging over the central U. The east coast trough will gradually breakdown the ridge over Florida with weak troughing developing.
1256 AM EST Tue Nov 7 2023 A crossing cold front will bring mainly clouds, breezy conditions and slightly cooler temperatures today.
1251 AM EST Tue Nov 7 2023 High pressure will extend across the region this week.
300 AM EST Tue Nov 7 2023 High pressure today will slide off the North Carolina coast.
1159 PM EST Mon Nov 6 2023 Aviation Secondary cold front is analyzed from Ludington to southern Wisconsin, though is becoming less distinct as clear skies ahead and clouds behind the front help to reduce the temperature gradient tonight.
(Today through Wednesday) Broad upper ridge centered over the western Gulf of Mexico extending northward through the Plains States with troughs off both the Atlantic and Pacific coasts. At the surface, high pressure was centered off the Louisiana coast. Wednesday could be a degree or two warmer than today, potentially the warmest day of the week, with the exception of the Mississippi coast, where southerly winds will be over cooler waters before reaching land.
530 AM CST Tue Nov 7 2023 Near record warmth is expected again across the Mid-South into Wednesday as temperatures rise into the lower 80s across most locations.
Winds aloft have increased to 35-45 kts at 700mb (approx 10K ft msl) as the west coast trough continues to sag slowly southeastward toward the state. Tonight - the trough axis and surface front move into northwest Arizona. As the trough passes through Arizona late tonight through Wednesday, some lower level moisture is forecast to enter northern portions of the state producing partly cloudy conditions.
One difference is that a Pacific Cold front will sweep across the area today and tonight, bringing colder temperatures and bringing the chance of snow to the valleys as well as the mountains. The best chance would be in a place like Casper, which may get just enough left front quadrant jet energy with the cold front to squeeze out some showers tonight. Wednesday will be cooler day across the area, but temperatures should only drop back to around seasonal averages. Conditions should improve at night as ridging builds into the area.
845 AM EST Tue Nov 7 2023 A crossing cold front will bring mainly clouds, breezy conditions and slightly cooler temperatures today.
- A cold front passage tomorrow will result in north-northwest winds ranging between 15 to 20 mph with gusts up to 30 mph. This will help push north a stalled boundary north through the area, effectively making it a warm front. The development of the stratus deck will limit solar insolation and some locations may be a few degrees cooler than forecast. The attendant cold front will pass through the forecast area Wednesday morning and will lead to approximately a 10 degree temperatures drop.
326 AM MST Tue Nov 7 2023 A low pressure/warm frontal system lifting across eastern Montana this morning continues to produce mainly rain over the northern zones. As the low pressure tracks into southern Saskatchewan, it will take the rain, fog and low clouds with it, resulting in partially clearing skies. This low will also join with a lee side low from Alberta, forming a deep stacked low this afternoon over southern Saskatchewan before moving east tonight and Wednesday. With the low developing north of the border, a tightening pressure gradient, weak cold air advection and downslope flow will help mix winds down to the surface. The proximity of the low as it moves east, could also produce some scattered precipitation overnight.
638 AM EST Tue Nov 7 2023 the trailing cold front pushing through Pennsylvania on Tuesday.
The surface cold front has already moved east and south of the forecast area. Look for the cooler air to continue funneling into northern and central Nevada today. Highs will be much cooler today with readings in the 40s and 50s.
Near record warmth is expected again across the Mid-South into Wednesday as temperatures rise into the lower 80s across most locations.
It will be cooler today given the cold front passage yesterday and the expected clouds. Rain showers are likely tonight largely due to a strong surge of warmer temps aloft and moisture into the area. With the low passing by just to the south Wednesday, the warmer temps will remains south of the forecast area, with highs here remaining near normal.
* Clouds may keep temperatures cooler today across portions of south central and central Nebraska.
625 AM EST Tue Nov 7 2023 Aviation Tranquil weather is forecast today as a high pressure ridge continues to build into the northern Great Lakes region. Northwest winds will gradually subside as the ridge builds in. Showers will then overspread our area through the day as a result of isentropic upglide north of the warm front and forcing from a 30 kt llj.
905 AM EST Tue Nov 7 2023 High pressure will extend across the region this week.
629 AM EST Tue Nov 7 2023 (Today through Wednesday) The mid-level ridging and high pressure will remain in place over the the Florida Peninsula. Highs temperatures will be a little bit warmer due to the northeast wind flow with mid to upper 80s across most of South Florida. Overnight lows will be in the 60s across much of the region, except for keeping in the low 70s in the far eastern metro along the Atlantic coast. Tomorrow will be a repeat, except for a few degrees warmer, mostly in SW FL, as the winds shift into a more easterly direction.
(Today through Wednesday) Zonal flow continues across the region with westerly flow around a weakly amplified ridge in the Gulf of Mexico. The ridge will shift eastward tonight and Wednesday as troughing moves across the Rockies. Low level winds will turn southerly as low pressure moves into the Midwest.
Showers has ended across much of the Valley outside of lingering showers over the Sierra and light snow over the highest elevations in the Central Sierra. The troughing that supported the recent rain will slide to the east with ridging following it over the area.
545 AM CST Tue Nov 7 2023 (Today through Wednesday) Zonal flow continues across the region with westerly flow around a weakly amplified ridge in the Gulf of Mexico. The ridge will shift eastward tonight and Wednesday as troughing moves across the Rockies. Low level winds will turn southerly as low pressure moves into the Midwest.
Outside of showers, the low-levels are quite moist, but widespread cloud cover will likely prevent much in the way of fog development this morning. Wednesday, we trend into drier conditions and more sunshine as weak ridging starts to build in, with high temps again holding in the 40s for most valley/plain locales.
542 AM CST Tue Nov 7 2023 (Today through Wednesday) Broad upper ridge centered over the western Gulf of Mexico extending northward through the Plains States with troughs off both the Atlantic and Pacific coasts. At the surface, high pressure was centered off the Louisiana coast. Wednesday could be a degree or two warmer than today, potentially the warmest day of the week, with the exception of the Mississippi coast, where southerly winds will be over cooler waters before reaching land.
With surface ridging across the southeastern United States pivoting east this morning, northeasterly wind flow will continue in earnest across our region remaining breezy along the immediate coast and light elsewhere. (Today through Wednesday) The mid-level ridging and high pressure will remain in place over the the Florida Peninsula. Highs temperatures will be a little bit warmer due to the northeast wind flow with mid to upper 80s across most of South Florida. Overnight lows will be in the 60s across much of the region, except for keeping in the low 70s in the far eastern metro along the Atlantic coast. Tomorrow will be a repeat, except for a few degrees warmer, mostly in SW FL, as the winds shift into a more easterly direction.
642 AM EST Tue Nov 7 2023 High pressure will extend across the region this week.
Veering winds aloft and above normal 850 mb temperatures will allow for highs this afternoon to climb into the low 80s out east to low 90s across the Big Country. The upper level disturbance west of the Baja Peninsula will erode ahead of a positively tilted trough advancing into the Plains, but the plume of upper level Pacific moisture will continue to stream overhead Wednesday and bring additional high clouds to the area.
521 AM EST Tue Nov 7 2023 A crossing cold front will bring mainly clouds, breezy conditions and slightly cooler temperatures today.
The mostly dry system bringing our cooler temperatures will also bring breezy winds out of the west to southwest today and Wednesday. Mid-level heights were falling across California and the Great Basin as an eastern Pacific trough axis approached the west coast. Wednesday will see a noticeable drop in temperatures as the upper level trough axis approaches and brings a cooler lower level air mass.
809 AM EST Tue Nov 7 2023 A crossing cold front will bring mainly clouds, breezy conditions and slightly cooler temperatures today.
450 AM PST Tue Nov 7 2023 A Pacific trough will bring cooler weather, higher humidity and a stronger afternoon sea breezy today.
Scattered showers continue to drift eastward under the influence of an upper level trough passing over northern California and southern Oregon. Snow levels of 5,000 feet will keep any light snowfall to the highest elevations. An upper ridge will follow the departing trough, bringing some dry days in the middle of the week.
This has lead to air temperatures at forecast time being noticeably warmer this morning.
Gusty winds and cooler temperatures will be the most notable effects with a system moving through the region today through Wednesday. However, gusty winds from the southwest will persist across the Mojave Desert/northwest Arizona today under the belt of stronger winds aloft preceding the approaching trough. A cold front across the Great Basin will steadily shift southeast today with frontal passage in southern Nevada this evening.
433 AM EST Tue Nov 7 2023 the trailing cold front pushing through Pennsylvania on Tuesday.
A cold front will move into the state from the NW Wed night.
529 AM CST Tue Nov 7 2023 (Today through Wednesday afternoon) WV imagery shows an upper trough just off the west coast this morning.
Attendant sfc cyclone will move away with it, and cold front will still well north of the CWA. Forecast highs in the lower 80s will put us 2-3 degrees off records for most climate sites each day.
Expect slightly warmer conditions today as southerly flow continues at the surface and the flow aloft turns more southwesterly.
* Cold front passes Wednesday night with a few light showers possible.
A low pressure system will continue to move through western Montana and north central Idaho through Wednesday. In the highest terrain (generally above 6000 feet), particularly across the Swan, WHitefish and Bitterroot ranges, significant snowfall is still anticipated. Tonight into Wednesday, northwest flow on the back side of the trough will linger over the region.
Today's highs are forecast to range from the low to mid 80s across the Hill Country, I-35 corridor, coastal plains and upper 80s across the Rio Grande. Wednesday's highs are forecast to reach the low to mid 80s for the most part with a few locations in the low 90s across the Rio Grande under partly cloudy skies. An approaching cold front to the local area through this period could bring isolated showers across Val Verde County.
Weak ridging will build over the area tomorrow allowing for a pretty quiet day around the area. It'll remain on the chilly side with highs in the 30s and 40s but warmer temps appear on the way in the extended.
An upper trough axis is currently progged to move eastward across the Rocky Mountain states over the next few days. In addition, the upper ridge in the Gulf will amplify, producing a mostly southwest flow aloft across the Southeast through Wednesday. Wednesday's weather will be almost a carbon copy of today's with perhaps a little more gradient wind as a low pressure area and trailing cold front move northeast across the plains states.
With surface ridging across the southeastern United States pivoting east today, northeasterly wind flow will continue in earnest across our region remaining breezy along the immediate coast and light elsewhere. Low temperatures will range from the low 60s to the west of Lake O, mid to upper 60s across the Gulf coast, and warm 70s along the immediate east coast due to the onshore wind flow.
315 PM EST Tue Nov 7 2023 Clouds will increase tonight through Wednesday ahead of a low pressure system advancing from the west. Showers and a few thunderstorms become likely Wednesday night when the low is forecast to track across Northern Indiana to Lake Erie.
1222 PM EST Tue Nov 7 2023 A crossing cold front will bring mainly clouds, breezy conditions and slightly cooler temperatures today.
MM/25 (Now through Wednesday) Zonal flow aloft prevails through Wednesday as upper ridging remains in place over the Gulf of Mexico. High temperatures today will top out in the low 80's for all areas, and this will likely be the story again for Wednesday. Tonight, temperatures drop into the lower to middle 50's for most areas. With the low level moisture improving tonight and the low level inversion in place thanks to radiational cooling it stands to reason we get patchy to areas of dense fog reducing visibility below a quarter mile.
The mostly dry system bringing our cooler temperatures will also bring breezy winds out of the west to southwest today and Wednesday.
1118 AM CST Tue Nov 7 2023 (The rest of today ) A sunny and warm day is in progress across eastern Oklahoma and northwest Arkansas with the exception of a few lingering clouds over the higher terrain of far southeast Oklahoma.
1125 AM CST Tue Nov 7 2023 (Today through Wednesday afternoon) WV imagery shows an upper trough just off the west coast this morning.
Scattered to numerous light rain showers prevail along and west of the Cascades in Oregon this morning but things are winding down as the upper trough axis is moving east of the Cascades. Drying is on tap tonight through Wednesday as upper ridging takes hold and we are looking forward to valley fog. Seas will gradually lower Tuesday night into Wednesday as this low moves eastwards. Wave heights will be lower Wednesday into Wednesday night as high pressure builds over the region.
Currently, a band of rain showers arc's from central MN southeast along the Mississippi River down toward Prairie du Chien along what appears to be a diffuse low level warm front on the return flow side of the ridge, along with the right entrance region of the upper level jet. It will be cooler today given the cold front passage yesterday and the expected clouds. Rain showers are likely tonight largely due to a strong surge of warmer temps aloft and moisture into the area. With the low passing by just to the south Wednesday, the warmer temps will remains south of the forecast area, with highs here remaining near normal.
Highs in the west will range from the low 30s to mid 40s, while to the east, highs get slightly above average, reaching the low to mid 50s. A cold front moves across the state Wednesday morning with colder temperatures settling during the day.
1103 AM EST Tue Nov 7 2023 A crossing cold front will bring mainly clouds, breezy conditions and slightly cooler temperatures today.
(This evening through Wednesday Night) After a morning of low clouds and fog, mostly sunny skies have returned to the region under upper level ridging aloft. The combination of these clouds and expected S/SW winds between 7-10 kts, the region should see more above normal overnight temps, with lows in the low to mid 60s. The upper level pattern will start to shift during the day Wednesday as we transition to more of a southwesterly flow ahead of an approaching trough digging across the Rockies. Models suggest we may see a little more cloud cover during day, but with the breezy southwest winds continuing, high temps should return back into the lower to middle 80s.
- Dry cold front sliding across Wednesday morning, with increasing winds out of the northwest in the afternoon (strongest over north central SD/Leola Hills) We're starting out with a couple areas of low pressure over southern Saskatchewan and north central NE/south central SD this afternoon, with the northern low being the main feature of interest for us.
107 PM EST Tue Nov 7 2023 Aviation Tranquil weather is forecast today as a high pressure ridge continues to build into the northern Great Lakes region. Northwest winds will gradually subside as the ridge builds in. Showers will then overspread our area through the day as a result of isentropic upglide north of the warm front and forcing from a 30 kt llj.
Clear and calm conditions will persist through the morning as we remain well under the influence of high pressure to our south giving us light south to southwest flow. Clouds along the western extent of the ridge have developed just to the west of us and will propagate east into NW AL through the afternoon. Highs are forecast to be in the high 70s to low 80s.
207 PM EST Tue Nov 7 2023 Quiet weather into this evening will give way to chances for scattered showers later tonight through Wednesday evening as a low pressure system moves through the area. This will also lead to sharp differences in Wednesday's high temperatures with near 50 in Michigan to the low 70s across central Indiana.
(The rest of this afternoon ) Warm and sunny conditions will prevail through the evening with highs in the lower 80s. Low temperatures will bottom out in the lower 60s for most areas, which is near the record highest for this date. During the day Tuesday, clouds will increase in advance of an approaching cold front. Even so, temperatures should still manage to pop into the lower 80s for many locations, which will also be close to record levels. A cold front will then move into northeast OK during the mid to late afternoon hours Wednesday based on the latest guidance, moving through the rest of the CWA by around midnight.
The cold front that is causing the wind will start to move across far northwestern Arizona late this afternoon and push south to southeastward across the state through Wednesday morning. Winds aloft have increased to 35-45 kts at 700mb (approx 10K ft msl) as the west coast trough continues to sag slowly southeastward toward the state. Tonight - the trough axis and surface front move into northwest Arizona. As the trough passes through Arizona late tonight through Wednesday, some lower level moisture is forecast to enter northern portions of the state producing partly cloudy conditions.
254 PM CST Tue Nov 7 2023 The short term forecast is highlighted by a cold front bringing strong northwest winds and chances (20-30%) for light rain and snow across northern North Dakota late tonight through Wednesday. Behind the front are clear skies and breezy westerly winds, while ahead of the front is extensive stratus, cooler temperatures, and patchy fog. Highs this afternoon will vary significantly depending on how far northeast the warm front can make it, with 20 UTC temperatures ranging from the lower 30s north central to the upper 50s southwest. The attendant cold front will enter northwest North Dakota after midnight tonight, moving southeast through the early morning hours and into daytime Wednesday. Highs on Wednesday will be cooler in the wake of the front, generally from the upper 30s north to mid 40s south.
Clear and calm conditions will persist through the morning as we remain well under the influence of high pressure to our south giving us light south to southwest flow. Clouds along the western extent of the ridge have developed just to the west of us and will propagate east into NW AL through theafternoon. Highs are forecast to be in the high 70s to low 80s.
Nevertheless, it's still a much warmer than normal day for November 7th. Expect lows to be in the low 50s on the Plateau and in the mid to upper 50s elsewhere Wednesday morning, and we should warm into the upper 70s and low 80s in the afternoon tomorrow. Cloud cover could once again try to keep temperatures below 80, but winds should be a bit stronger tomorrow afternoon, so perhaps mixing will win out and push our temperatures into the low 80s.
1157 AM CST Tue Nov 7 2023 Temperatures are running about a degree or two cooler than 24 hours ago, mainly due to a lingering deck of slowly-eroding low level stratus. Highs will top out in the lower 80s with mostly clear skies and gusty southwest winds. AC3 Near record warmth is expected again across the Mid-South into Wednesday as temperatures rise into the lower 80s across most locations.
Snow levels will be around 4000-5000 feet MSL with accumulations of 1 to 2 inches on the highest peaks. Then high pressure builds into the area for the remainder of the week with stagnant conditions developing in the lower valleys.
