Gusty north winds will develop behind a cold front moving across southern Nevada and surrounding areas tonight and Wednesday.
1202 PM EST Tue Nov 7 2023 High pressure will extend across the region this week.
142 PM MST Tue Nov 7 2023 Update for today: Much drier and warmer conditions than forecasted occurred behind the dryline. For tonight, the low is forecasted to begin moving south and east. With some cooler air from the north, lows should drop into the 30's. Tomorrow, the low is forecasted to move further to the south and east with higher surface pressure moving in as the upper trough axis swings through the area. With colder air in the area, high temperatures are forecasted to be much cooler in the 50's and 60's.
256 PM EST Tue Nov 7 2023 High pressure will maintain dry weather through most of Wednesday.
-Relatively quiet into the weekend with cooler readings.
A large positively-titled trough begins off the Pacific this afternoon. As the trough approaches the southern Great Plains, a cold front begins to sag into the Panhandle.
Mean layer ridging remains centered over southern Mexico and the Yucatan. Water vapor imagery highlights a broad swath of subsidence across Florida and the northern Bahamas, culminating in super dry air on the southwest flank of a developing cyclone east of Bermuda. A small SFC anticyclone is nestled into the northeastern Gulf of Mexico. The forecast calls for near-nil rain chances and highs in the lower 80s. High pressure initially centered over the Southeast US and northern Florida will slide east and broaden over the western North Atlantic.
A persistent subtropical ridge extending from the Gulf Coast to South Atlantic Coast region will maintain warm (near-record) and dry anticyclonic flow across north and central GA through mid week.
(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.
Low level moisture will be reinforced overnight as the ridge axis of northern Ontario high pressure shifts east resulting in an east-northeast veering of local surface winds maintaining cloudy conditions across the eastern half of the CWA (east of I- 75/US-23). A further shift to easterly winds occurs by Wednesday morning as an area of low pressure begins developing along the stalled frontal boundary across the mid-Mississippi valley tied to an inbound upper trough ejecting out of the northern Rockies.
High pressure over the local area today will keep most shower chances from the forecast. Highs this afternoon reaching the lower to mid-80s. Dry air will continue to filter in across central Florida today as high pressure builds across the Southeastern U. Minimum relative humidity values are forecast to drop into the low 30s to low 40s generally along and to the north of I-4.
1000 AM PST Tue Nov 7 2023 Snow showers will end in the higher elevations of the Sierra Nevada this afternoon.
(This evening through Wednesday) Current satellite showing good cumulus development over the higher terrain in response to daytime heating paired with modest low-to- mid level instability. Perhaps a few sprinkles over the ridge of the Gabilan Range and Santa Cruz Mtns. Otherwise quiet weather through mid week with cooler overnight temps behind yesterday's cold front.
Currently, low level cloud cover has mixed out for the most part as the ridge of high pressure has made it to be aligned along Lake Michigan and will drift east into tonight. Looks like the instability will wain as the low level moisture transport pushes east on Wednesday, so am just expected a crummy, rainy day with some breaks here and there.
This Evening/Tonight Currently this afternoon, ridging is expanding from the west with a surface front to the north. An area of low pressure will continue to develop in the High Plains with this trend keeping dry conditions and westerly winds into the early evening hours. With this system, the low-level jet will also strengthen through the day with its maxima from Kentucky towards Indiana and Ohio. They are as such: Chattanooga Knoxville Tri-Cities Oak Ridge 84(2005) 81(2005) 79(2022) 80(2022) (Wednesday night through next Tuesday) Key Messages: 1.
Regardless, we're on track to have a much warmer than normal day. This has lead to air temperatures at forecast time being noticeably warmer this morning.
1116 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.
Both the Euro and the GFS seem to be agreement with each other regarding the placement of the ridge, despite the GFS placing the ridge slightly further south. Regardless of the placement of the ridge, overnight lows drop into the low 60s west of I-55. Dry conditions will continue tomorrow as the ridge remains in place over the southeastern US. Afternoon highs are forecasted to peak in the low to mid 80s.
The main event for the short term forecast begins Wednesday night as a cold front moves into the area. To the south of the front, lows stay slightly warmer in the 50s to near 60F.
(Tonight through Wednesday) A majority of Central Alabama warmed into the lower 80s this afternoon. Under clear skies and calm winds this evening, temperatures have dropped quickly with many areas 20-25 degrees cooler at 8pm than the 4pm readings. 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.
451 PM MST Tue Nov 7 2023 - Much cooler Wednesday.
638 PM EST Tue Nov 7 2023 High pressure will maintain dry weather through most of Wednesday.
959 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.
* Cold front will move through Wed afternoon/evening and will return temps back to seasonal normals for the next several days. At the surface, low pressure is situated over Western KS with unseasonably moist return flow from TX through Eastern OK and into the eastern half of KS. A cold front is expected to move through during the day Wed as both the northern and southern stream upper impulses slide east.
704 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.
424 PM MST Tue Nov 7 2023 Update for today: Much drier and warmer conditions than forecasted occurred behind the dryline. For tonight, the low is forecasted to begin moving south and east. With some cooler air from the north, lows should drop into the 30's. Tomorrow, the low is forecasted to move further to the south and east with higher surface pressure moving in as the upper trough axis swings through the area. With colder air in the area, high temperatures are forecasted to be much cooler in the 50's and 60's.
- A cold front passage overnight will result in north-northwest winds ranging between 15 to 20 mph with gusts up to 30 mph tomorrow. Today: Water vapor imagery this afternoon shows largely zonal flow across the CONUS while at the surface, a weak center of low pressure is approaching from the northwest dragging with it a front while a west- to-east oriented stationary front sits across northern Kansas. As far as lows go, expect to see temperatures fall into the low-to-upper 40s with northwesterly winds.
Gusty southwest winds will continue into this evening as a dry cold front slides southeastward across northern Arizona.
511 PM EST Tue Nov 7 2023 High pressure will maintain dry weather through most of Wednesday.
550 PM CST Tue Nov 7 2023 (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.
652 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.
) Still, the environment remains stable given that we're still dominated by high pressure. However, a warm front has become established to our immediate north as a sort of foreboding with a strong low pressure center brewing over the Great Plains. Surface winds are starting to increase, so look for even warmer temperatures tomorrow with dew points now in the 50s area-wide.
It turns drier and slightly warmer for the rest of the week, with afternoon highs about 5 degrees above normal this weekend. An upper level trof continues eastward across The Treasure State, today. Accumulating snow is generally confined to the mountains/mountain passes; however, some accumulating snow is forecast to occur across some of the lower elevations of south central and southwest Montana.
Update for today: Much drier and warmer conditions than forecasted occurred behind the dryline. For tonight, the low is forecasted to begin moving south and east. With some cooler air from the north, lows should drop into the 30's. Tomorrow, the low is forecasted to move further to the south and east with higher surface pressure moving in as the upper trough axis swings through the area.

512 PM CST Tue Nov 7 2023 (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.
-thor PREVIOUS DISCUSSION: 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.
/NEW/ /Through Wednesday/ Breezy south winds will continue into the overnight with warm overnight lows in the low to mid 60s (~10-15 degrees above-average for this time of year).
Our southern tier counties will reach at least the low-mid 70s by peak diurnal cycle.
805 PM EST Tue Nov 7 2023 Another quiet night is expected across the local area with high pressure remaining overhead.
539 PM CST Tue Nov 7 2023 (This evening through Wednesday) Most of the forecast area will experience one more near day of near record warmth tomorrow before the arrival of our next cold front.
(This evening through Wednesday) Most of the forecast area will experience one more near day of near record warmth tomorrow before the arrival of our next cold front.
That said, one last hurrah will occur late tonight into early Wednesday morning as the cold front swings through and brings another surge of strong winds. Temperatures on Wednesday will be slightly cooler as well due to the cold front, with highs in the mid 40s to low 40s across the area (near normal values for this time of year).
635 PM EST Tue Nov 7 2023 Aviation - Showers and isolated storms for Wednesday A weak wave of low pressure tracks in from the southwest Wednesday and gradually deepens as it does. The wave of low pressure pulls east of the region later Wednesday and into Wednesday night.

Perhaps a few sprinkles over the ridge of the Gabilan Range and Santa Cruz Mtns. Otherwise quiet weather through mid week with cooler overnight temps behind yesterday's cold front.
High pressure remains layered across the mid/southern Atlantic states, as a weak upper ridge pattern translates into the eastern Gulf region. Afternoon highs look to climb into the lower/perhaps mid 80s for most spots.
Clouds were decreasing this evening as cooler, drier air comes in from the northwest.
The 00z evening sounding at KEY highlighted a modestly moist boundary layer below a formidable ridging inversion based at around 850 mb. Temperatures are in the lower to mid 70s across the island chain at this early Wednesday morning hour. An area of high pressure currently centered over northern Florida will slowly migrate eastward into the western North Atlantic. This high will be reinforced by a secondary high, resulting in a modestly tightening gradient and bouts to freshened breezes.
There should be a lull in the rain this afternoon, mainly south of I-96, as the 850 mb warm front lifts north. However an additional band of convection is shown to develop along the 850 mb cold front late in the day, which sweeps east across the area this evening.
These winds will advect ample moisture across the Midsouth ahead of an approaching cold front set to arrive late tomorrow night.
The latest run holds on to the lower visibilities as far north as highway 84. Still looking for fog to develop across the southeast zones although hi res models are keeping the lower visibilities just south of the area.
(Today and Tonight) Positive tilt upper trough over the western CONUS early this morning will split into a couple pieces over the next couple days as it progresses east across the country. A trailing cold front will enter NE OK this afternoon and sweep south and east across the forecast area tonight.
1223 AM EST Wed Nov 8 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.
322 AM EST Wed Nov 8 2023 A warm front lifts northward today into the southern portion of the Great Lakes. High temperatures will be quite varied through the region, ranging from the lower 50s in south central Lower Michigan to the middle 70s over central Indiana.

Currently - A weakening ridge straddles the Florida Peninsula and is resulting in gentle to moderate northeasterly breezes across the Keys this evening. Ridging also dominates through the lower and mid levels with nearly zonal flow through the upper troposphere. Short Term Update - Surface winds will remain gentle out of the northeast to east through the overnight period as surface ridging will remain across Florida. Deeper layer ridging is expected to become more prominent and will maintain an environment that is poor for shower formation. Expect over night lows to settle broadly in the lower 70s with some locations possibly seeing some radiational cooling down to near the dew point. A ridge across Florida will maintain gentle to moderate northeast to easterly breezes across Keys waters through the overnight period.
128 AM EST Wed Nov 8 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.
239 AM CST Wed Nov 8 2023 Morning fog and much cooler in central Kansas today.
/Issued 1232 AM CST Wed Nov 8 2023/ /Through Thursday Night/ After one more warm and breezy day Wednesday, an unsettled pattern will dominate the rest of the short term period with showers and much cooler conditions in store. Highs Wednesday will be similar to the first half of the week, only slightly cooler with continued breezy SSW winds. Temperatures will peak in the low to mid 80s for most, outside of the Big Country/western North Texas locations who will climb into the upper 80s/low 90s. By late Wednesday evening, the cold front will be passing through the Red River Valley and on its way to North & Central Texas.
527 AM CST Wed Nov 8 2023 (Today and tonight) The combination of a strong low level thermal ridge and southwest flow will result in hot temperatures across the area for one more day. A cold front will move south across the area tonight and exit the area Thursday morning.
The upper level ridge axis moves to the east today as troughing moves across the Rockies. The cold front will be just to our northwest Thursday morning, becoming parallel to mid level winds and likely stalling out.
501 AM CST Wed Nov 8 2023 (Today through Thursday Night) On Wednesday, upper lvl ridging over Arkansas in cohesion with an approaching sfc cold front from the west and a sfc area of high pressure located along the Gulf Coast region of the CONUS will continue to usher in brisk southerly winds into the CWA. Expect brisk conditions with gusty winds, much warmer than normal temperatures, and partly cloudy to mostly clear skies. On Wednesday Night into Thursday Night, a cold front will approach the Natural State from the northwest.
(Today and tonight) The combination of a strong low level thermal ridge and southwest flow will result in hot temperatures across the area for one more day. A cold front will move south across the area tonight and exit the area Thursday morning.
543 AM CST Wed Nov 8 2023 Near record to record warmth is expected again across the Mid-South today with temperatures reaching the lower 80s. A slow moving cold front will bring a return of rain chances beginning late tonight into Thursday and persisting across areas south of I-40 into the upcoming weekend.
Current temperatures are mostly a little cooler compared to 24 hours ago except for the windier spots which are running around 5-10 degrees milder. The gusty north to east winds are forecast to peak by midday, then gradually relax later this afternoon and evening as ridging builds in from the west. As winds decrease by this evening, clear skies and a cooler and drier airmass will allow for cold overnight low temperatures in the Central Valley. Cooler portions of the valley will dip into the lower to mid 30s. Upper ridging will be the dominant feature into the weekend.
540 AM CST Wed Nov 8 2023 Morning fog and much cooler in central Kansas today. The greatest impact from reduced visibility in areas of dense fog are expected to translate along and just behind the front thru mid-morning, from the I-70 corridor to roughly just south of the highway 50 corridor. Much cooler and drier air will advect over the entire area tonight and Thursday with daytime highs below climo and generally just below 60F.
617 AM EST Wed Nov 8 2023 Upper ridging and high pressure will keep conditions dry with above normal temperatures through Thursday.
