911 PM CDT Mon Oct 25 2021 High pressure will continue to slide east overnight, though seasonably cool low temperatures are expected under clear to mostly clear skies.
607 PM CDT Mon Oct 25 2021 We have seen gradual clearing from the south today as low pressure over the over IN moves off to the east. A north-south oriented ridge of high pressure will move through the region tonight and shift off to the east Tuesday.
/issued 314 PM CDT Mon Oct 25 2021/ Dry and mild conditions are expected again tomorrow as a ridge shifts out of the Plains and across the Mississippi River Valley.
/Issued 329 PM EDT Mon Oct 25 2021/ Pre-frontal trough is noted on the radar this afternoon across NW GA. The trough will continue to push south and east, but should remain weak. High pressure will build in from the west overnight and into tomorrow. The gradient will tighten a bit as high pressure builds in from the west and a coastal low moves up the eastern seaboard.
A small patch of low stratus has helped keep areas of northeast Kansas into northwest Missouri warmer, with readings in the middle 40s. Upper ridging builds into the region today in advance of the next highly amplified trough. Highs will be warmer today with readings reaching the upper 50s to middle 60s.
High pressure with CAA building into the region today. Clear tonight with cooler conditions early.
An upper level ridge will follow, and a return of warmer air will see highs reaching to or just above climatological normals.
355 AM EDT Tue Oct 26 2021 A crossing upper low will keep the clouds and scattered rain showers locked in over the region today. Scattered showers and much cooler temperatures can be expected today. Stronger wind gusts are anticipated over the highest ridge tops, generally above 3000ft. Dry weather will return Wednesday as a ridge builds in behind the exiting low.
this should be enough for temperatures to bottom out in the lower to middle 40s. As clouds scatter out tonight, overnight lows will dip into the low 30s. A sharp upper ridge will spread over the Midwest tomorrow with strong subsidence streaming into central Indiana. Models suggest strong ridging in place over Indiana within a highly amplified pattern aloft. A deep trough will be moving through the plains. Thus with lingering subsidence and weak high pressure at the surface this should lead to a dry day.
1135 PM CDT Mon Oct 25 2021 We have seen gradual clearing from the south today as low pressure over the over IN moves off to the east. A north-south oriented ridge of high pressure will move through the region tonight and shift off to the east Tuesday.
1044 PM CDT Mon Oct 25 2021 An upper level trough was over the OH Valley region with upper level ridging over the Plains this afternoon. The low level cloud deck over our area will break up and clear out tonight. Warmer high temperatures can be expected on Tuesday with the upper level ridge moving eastward into the central US, along with plenty of sun. Looking at the latest CAMs, precipitation associated with an approaching deep upper level trough moving into the Plains should remain just west of our forecast area Tuesday night, although there will be increasing cloudiness. GKS Showers and possibly a few embedded storms will spread eastward into central and eastern MO Wednesday as upper level divergence increases over our area ahead of an upper level low moving eastward through OK.
A deep trough down the West Coast has allowed an atmospheric river to develop along its southern edge. Clouds will increase though tonight as the trough shifts eastward. Low pressure will develop Tuesday afternoon over northeast Colorado. A high pressure ridge oriented north to south will slide east to the western Great Lakes and Mid South. Farther east closer to the ridge, winds will be quite a bit more subdued, although some gusts are possible later in the day into WI.
The strong upper ridge building into the MS Valley will keep us dry through Wednesday.
359 AM EDT Tue Oct 26 2021 A strong cold front will move offshore early today, followed by high pressure today through Wednesday.
The weekend slide will begin with lingering rain showers in Minnesota as the upper level trough continues to march eastward.
Upper level ridging will crest over the state later today but exit quickly off to the east this evening. Meanwhile, the progressive weather pattern of late will continue with a deep and significant trough working its way through the intermountain west. Moisture will be drawn into the state as the system approaches with widespread showers developing in advance of the approaching warm front.
and as an potent upper trough approaches the region.
Gusty south winds will persist during the day through Tuesday evening in advance of next low pressure system. /Issued 911 PM CDT Mon Oct 25 2021/ High pressure will continue to slide east overnight, though seasonably cool low temperatures are expected under clear to mostly clear skies.
1149 PM CDT Mon Oct 25 2021 Warmer temperatures will be in store for the region tomorrow, however some low clouds could develop with returning low-level moisture thus hampering full daytime heating.
A high pressure system in the Midwest will continue to build continuing the dry weather trend for one more day. Weakening upper ridge will depart Wednesday morning as a deep longwave trough advances through the Great Plains. This trough will morph into 2 distinct features by Wednesday night.
251 AM MDT Tue Oct 26 2021 Upper level analysis depicts a highly amplified trough pivoting through the Four Corners region. Widespread upper lift downstream of the trough axis is clearly evident on water vapor and IR imagery and a look at regional radar imagery shows precipitation stretching from central MT southward into northern AZ. Temperatures will cool enough for a mix of rain and snow across the higher elevations of the Black Hills, where an inch or so of snow is possible by Wednesday morning. Rain chances will taper off Wednesday as the upper trough pivots through the southern Plains and into the Midwest by Wednesday evening.
The mid-level ridge mentioned above will continue to advance eastward across the Plains and into the MS Valley tomorrow, downstream from an amplified trough tracking eastward across the western CONUS. After morning stratus clouds disperse, we expect a mostly sunny day but cooler day, with highs only reaching the l-m 60s. During the day on Wednesday, a well-defined vort max within the base of the trough to our west is predicted to deepen into a negatively- tilted wave as it tracks southeastward across OK.
337 AM CDT Tue Oct 26 2021 After a chilly start to the day, sunshine will return across the Midwest as weak High pressure ridging occurs today. This ridging begins exiting the region tonight into Wednesday as the next weather system develops across the southern Plains.
Relief from the recent wet and muggy weather across the region finally appears to be in store; a ridge of higher geopotential heights builds in over the region, while increasing surface pressure implying surface ridging is recognized in the latest short-range model guidance. Wednesday will be perhaps a few degrees cooler, owing to a slight northerly turning of the winds.
As the trough digs across the Southern Plains, it begins taking on a negative tilt going into Wednesday afternoon. At the surface, a weak cold front continues pushing off to the south-southeast through tonight with the front well offshore by Tuesday morning. A cooler, drier airmass moves south across the forecast area following the FROPA. Depending on how far this warm front makes it into the region will ultimately determine where the severe weather potential will be going into the short term period.
Otherwise, an increasing cu field with the return Srly low level flow, and cirrus shield from the SW from the remnants of TD Rick over Cntrl old MX atop the cooler and drier air mass in place should result in cooler max temps Tuesday, with readings remaining below record territory for a change in wake of near to record temps observed the last couple of days over the region.
Upper trof will move from the inter-mountain West early this morning across the Rockies this afternoon. Forcing for ascent will ramp up during the evening as the upper trof emerges onto the high Plains with convection expected to develop just ahead of the surface dry-line and merging cold front over western Kansas into northwest Oklahoma.
Plenty of sun is ahead for Tuesday with the highs close to 55. Lows will be close to freezing Tuesday night with fair weather Wednesday with highs close to 55. The low pressure system that brought the rain to area over the weekend and into today will continue to slide east. A breeze in the morning to 20 kts is expected to die down in the afternoon as the low level jet moves away from the area. However, lighter winds and cool temperatures remain allowing another chance at frost as temperatures drop into the low to mid 30s in many locations as drainage occurs from southern Lower Michigan.
1248 AM EDT Tue Oct 26 2021 A crossing upper low will keep the clouds and scattered rain showers locked in over the region today. Lowered Pops as best large scale ascent is driving southeastward in the base of the passing trough. Scattered showers and much cooler temperatures can be expected today. Dry weather will return Wednesday as a ridge builds in behind the exiting low.
/issued 242 PM CDT Mon Oct 25 2021/ It will be a quiet start to the evening as low-amplitude upper level ridging will just begin shifting to the east of the forecast area. That will be quickly followed by height falls ahead of an upper level trough moving across the Great Basin and 4-Corners region. A cold front will push through the region early Wednesday as the upper low/trough axis passes just to our east with highs in the mid 60s/70s Wednesday. The region will be under northerly flow aloft going into late week as the upper low slows in forward speed as it deepens across the Mississippi River Valley.
The system that brought wind and rain to the area yesterday will move east of the area today, bringing clear skies but northerly breezes are expected to lead to cooler temperatures across the area today. High pressure ridging spreads across the region through the end of the week keeping the area dry and warmer which will continue through the rest of the week.
Warm and mostly dry conditions will prevail today and Wednesday as weak high pressure builds into the central Gulf of Mexico from the north.
302 AM CDT Tue Oct 26 2021 (Issued 300 AM CDT Tue Oct 26 2021) Today through Wednesday: With the upper level closed low now off to the east we will a ridge push in from the west. Into Wednesday, similar conditions will persist with the ridge overhead and no moisture or forcing to be had thus keeping the area mostly dry. However as we move into the afternoon and evening we will see a new area of low pressure from the west start to push in.
116 AM EDT Tue Oct 26 2021 Areas of drizzle or light showers will continue overnight as a cold front moves east of the area. High pressure and a drier airmass will build into the region through mid week. Overnight lows will range from the lower 40s in the northwest to the mid 40s along and southeast of the I-71 corridor. In addition, expect some of the lower clouds to linger through the day especially across the central Ohio area.
A high pressure ridge at the surface and aloft migrates slowly eastward across the area through tonight, offering cool/dry seasonal 60s/40s. On Wednesday, these ridge axes translate to the east, and a negatively titled upper trof of low pressure develops/evolves upon its approach from the west.
/issued 314 PM CDT Mon Oct 25 2021/ Dry and mild conditions are expected again tomorrow as a ridge shifts out of the Plains and across the Mississippi River Valley. Temperatures will be a bit cooler tomorrow featuring highs in the mid 60s to near 70 with slightly warmer temperatures returning Wednesday. By Wednesday morning the ridge will be centered over middle Tennessee and Alabama.
215 AM MDT Tue Oct 26 2021 An area of rain showers will move east through NE Montana today on the back side of a cold front. A dry upper trough will pass through the area on Wednesday with gusty west winds.
1224 AM CDT Tue Oct 26 2021 Upper level ridging over the region this morning, will exit to the east by the end of the period. Tonight Through Wednesday An upper ridge will move out of the Plains tonight, across Arkansas Tuesday and to the Appalachians Wednesday. An upper low along the west coast will move to the Rockies Tuesday. This upper low will move out of the Rockies and into the Plains Tuesday night and Wednesday. A cold front is across Louisiana this afternoon with high pressure and clear skies over Arkansas. High pressure will continue over Arkansas Tuesday but the cold front will return as a warm front late Tuesday. Lows tonight will be in the low 40s to mid 50s, and upper 40s to lower 60s Tuesday night.
200 AM EDT Tue Oct 26 2021 The cold front is pushing southward across north Georgia and across the Atlanta metro at this hour with breezy northwest winds and a considerably drier airmass in its wake. The chance for any additional showers has now ended, and high pressure will continue to build southward into the area through the night. /Issued 329 PM EDT Mon Oct 25 2021/ Pre-frontal trough is noted on the radar this afternoon across NW GA. The trough will continue to push south and east, but should remain weak. High pressure will build in from the west overnight and into tomorrow. The gradient will tighten a bit as high pressure builds in from the west and a coastal low moves up the eastern seaboard.
743 AM EDT Tue Oct 26 2021 A crossing upper low will keep the clouds and scattered rain showers locked in over the region today along with steady or falling temperature. Scattered showers and much cooler temperatures can be expected today. Stronger wind gusts are anticipated over the highest ridge tops, generally above 3000ft. Dry weather will return Wednesday as a ridge builds in behind the exiting low.
Latest water vapor imagery shows upper level ridging overhead this morning with a deep western trough extending across the CA/AZ/NV border. This deepening trough is forecast to quickly move into the High Plains towards 00z this evening. Ahead of this, strong low-level moist advection is expected with surface dewpoints reaching the lower to mid 50s across much of the southern half of the CWA by 00z. Otherwise, generally sub-severe thunderstorms are likely through the overnight across much of the CWA with locally heavy rainfall the primary hazard ahead of the eastward moving cold front. Rain chances, heavy at times, continue through much of Wednesday as the main trough and associated surface cold front slowly move eastward through the area. With already saturated soils, some localized flash flooding is possible within the areas of the higher rainfall rates.
951 AM EDT Tue Oct 26 2021 Expect cool temperatures and decreasing clouds today through Wednesday as high pressure moves across the Great Lakes.
The latest surface analysis places a 1019mb high pressure over Mid Mississippi Valley region with a deep 998mb low off the coast of Maryland. The upper low is expected to deepen further and fully cutoff from the mean flow late Wednesday night. Fortunately for us, the upper low will be so deep that any chance of severe weather will remain well to our south, or along the Gulf Coast. The EURO tries to bring a tiny warm sector into our area, but the cyclone will likely be occluded before making it into north Mississippi.
Given the increasing confidence in the strong winds, most of the High Wind Watch has been upgraded to a High Wind Warning. Behind this system, upper level ridging will build in for the second half of the week, which will result in a warming trend through the end of the work week and otherwise quiet weather.
811 AM EDT Tue Oct 26 2021 A crossing upper low will keep the clouds and scattered rain showers locked in over the region today along with steady or falling temperature. Scattered showers and much cooler temperatures can be expected today. Temperatures will be steady or fall over the course of the day with temperatures down into the 30s in the ridges of eastern Preston and Tucker counties. Stronger wind gusts are anticipated over the highest ridge tops, generally above 3000ft. Additionally, if the boundary layer deepens enough to form any ice, ridges could also see some graupel with a saturated, supercooled, and unstable boundary layer this afternoon. Dry weather will return Wednesday as a ridge builds in behind the exiting low.
638 AM CDT Tue Oct 26 2021 Upper level high pressure over the region will slide to the east today with east to southeast winds continuing. Upper level ridging will crest over the state later today but exit quickly off to the east this evening. Meanwhile, the progressive weather pattern of late will continue with a deep and significant trough working its way through the intermountain west. Moisture will be drawn into the state as the system approaches with widespread showers developing in advance of the approaching warm front.
The second half of the week will be dry and warm as high pressure builds over the west. High pressure over the eastern Pacific will continue to build over the region.
The high-humidity environment present between precipitation occurrences will allow low stratus and patchy fog to develop. Also, the high-elevation snow will create slick roadways over area mountain passes (think Lost Trail Pass) and high valleys of southwest Montana (think Georgetown Lake). A cold front is anticipated to move across the Northern Rockies from the west this evening through the overnight hours, bringing another round of precipitation and lowering snow levels a bit. Upper level flow will intensify with the passage of the Tuesday evening cold front and mix down to valley elevations by Wednesday afternoon.
Hennig (Today through Wednesday afternoon) Everything continues on track for strong winds in the Guadalupe Mountains and windy conditions elsewhere as an upper level trough moves across the desert southwest today. Have kept the High Wind Warning going through 09Z to allow for uncertainties in the timing of the trough but winds may well decrease before the expiration time. The trough will push a Pacific cold front through this evening which could cause storms to develop in the eastern Permian Basin as the front encounters better low level moisture. Temperatures today will again be near record highs due to the westerly downsloping flow but then cooler air settles in tonight behind the Pac front with cold air advection continuing tomorrow as low level winds become more northerly.
752 AM EDT Tue Oct 26 2021 A crossing upper low will keep the clouds and scattered rain showers locked in over the region today along with steady or falling temperature. Scattered showers and much cooler temperatures can be expected today. Stronger wind gusts are anticipated over the highest ridge tops, generally above 3000ft. If the boundary layer deepens enough to form any ice, ridges could also see some graupel with a saturated, supercooled, and unstable boundary layer this afternoon. Dry weather will return Wednesday as a ridge builds in behind the exiting low.
452 AM MDT Tue Oct 26 2021 Upper level analysis depicts a highly amplified trough pivoting through the Four Corners region. Widespread upper lift downstream of the trough axis is clearly evident on water vapor and IR imagery and a look at regional radar imagery shows precipitation stretching from central MT southward into northern AZ. Temperatures will cool enough for a mix of rain and snow across the higher elevations of the Black Hills, where an inch or so of snow is possible by Wednesday morning. Rain chances will taper off Wednesday as the upper trough pivots through the southern Plains and into the Midwest by Wednesday evening.
549 AM CDT Tue Oct 26 2021 After a chilly start to the day, sunshine will return across the Midwest as weak High pressure ridging occurs today. This ridging begins exiting the region tonight into Wednesday as the next weather system develops across the southern Plains.
High pressure will build into the area for Wednesday bringing slightly warmer conditions and lighter winds. Upper level ridging will build in for tomorrow as heights rise over the region.
700 AM EDT Tue Oct 26 2021 A crossing upper low will keep the clouds and scattered rain showers locked in over the region today. Scattered showers and much cooler temperatures can be expected today. Stronger wind gusts are anticipated over the highest ridge tops, generally above 3000ft. Dry weather will return Wednesday as a ridge builds in behind the exiting low.
From Wednesday onward, warmer and dry conditions are anticipated, with generally light winds. An active cold front is noted east of Flagstaff this morning. The trough driving this front moves into western Colorado later this morning, with frontal precipitation over the eastern zones rapidly decreasing by early afternoon.
630 AM EDT Tue Oct 26 2021 A strong cold front will move offshore early today, followed by high pressure today through Wednesday.
The region remains under nwly flow aloft ahead of the ridge axis that will quickly move ewd today. Boundary to lift nwd as warm/moist airmass advects nwd ahead of the approaching trof. Line of convection to develop to our w late this evening and push ewd along the associated cold front tonight, approaching our region after sunrise Wednesday. Nevertheless, it does appear that at least modest instability will be in place across the srn half of the region to combine with very strong deep-layer shear as the trof/cold front moves across our region. Upper trof to become cut off by Wednesday night, allowing for some additional convection to potentially wrap around into our far nrn areas in SE OK/SW AR.
DDV (Issued 300 AM CDT Tue Oct 26 2021) Today through Wednesday: With the upper level closed low now off to the east we will a ridge push in from the west. Into Wednesday, similar conditions will persist with the ridge overhead and no moisture or forcing to be had thus keeping the area mostly dry. However as we move into the afternoon and evening we will see a new area of low pressure from the west start to push in.
Short term guidance struggles with mixing the stratus out during the afternoon, and while some weak warm advection is noted over central Kansas, opted to lower highs today by around 5 degrees, ranging from the low 60s in far eastern KS to the low 70s in north central Kansas.
933 AM EDT Tue Oct 26 2021 A weak cold front continues to push south through central and southwest Florida this morning. This front will wash out by this evening as high pressure builds in from the north. Interaction between high pressure to the north and a weak cold front over southwest Florida will produce northwest winds around 10-15 knots today. Decreasing winds less than 10 knots expected on Wednesday as high pressure settles in over the eastern gulf.
Low temperatures tonight will be in the lower and mid-30 in central and north-central Wisconsin and range from the upper 30s to mid-40s elsewhere. On Wednesday, the longwave trough will move slowly east toward the area. Series of deepening upper troughs and lows will drive later periods, but bulk of impactful weather will likely occur mid week. Confidence from ensemble members remains high with upper trough evolving into closed low south of the area late Wednesday. It will also strengthen while energy from northern trough approaches from the west, slows, and weakens.
As the trough axis pushes over the front range of the Rockies, clouds begin to clear across the lower elevations overnight while lingering near the mid and high elevations of the central and northern mountains. The heaviest precipitation has moved eastward along with the cold front. This will lead to some chilly conditions (near freezing in the low valleys) tonight before warming just a couple degrees tomorrow.
