- Dense fog across the Highway 183 corridor this morning - Gusty northerly winds through the day (around 35 mph gusts) - Cooler Highs(50s) by Thursday. warming back up above normal through the weekend - Dry though the period Fog development along the leading edge of an advancing cold front this morning is the highest impact weather of the next several days. Gusty north winds Today will bring frequent gusts of around 35 mph and may peak higher as sustained wind speed in the low 20s mph range persist through the day. Box and whisker plot suggest the temps at Elkhart to reach at least 64 degrees and as warm as 67, and farther northeast at Hays, the same considered range of outcomes varies several few degrees cooler - from 60 to 64F.
534 AM CST Wed Nov 8 2023 (Today through Thursday afternoon) WV imagery shows the upper trough extending from Manitoba to California, leaving southwest flow aloft over West Texas and Southeast New Mexico. Despite downslope warming today, thicknesses come down w/the approaching trough, and highs should come a degree or so cooler than yesterday, w/increasing high clouds to help mitigate things. Tonight, the much-advertised cold front arrives, w/the latest NAM pegging fropa at KMAF ~ 06Z. Forecast soundings show minimal instability w/the front, but enough for rain showers beginning around 06Z and even a little thunder over the lower Trans Pecos. Showers/drizzle will increase across the area, mainly south with the front, and as the upper trough approaches.
These showers will bring snow to the higher terrain, but little to no impact is anticipated. A ridge of high pressure moves over the region on Thursday giving the area a short respite in precipitation.
A fall storm system will exit the area today, allowing high pressure to return for the end of the work week.
538 AM CST Wed Nov 8 2023 (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.
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.
Stable conditions have arrived as an upper level ridge has started to move over the area.
442 AM MST Wed Nov 8 2023 - Light to moderate snow across the higher elevations today and tonight, with some travel impacts anticipated through early Thursday morning. - Cooler weather today, with rain and snow showers across the urban corridor, but little to no accumulation and limited impacts.
A pressure trough continues to move west to east switching the winds from southerly to southwesterly. An upper level low located over southern Manitoba continues to push eastward this morning placing the west on the backside of the low. In addition a cold front located over northwestern North Dakota continues to push southward leading to strong pressure rises behind the front. Wrap around precipiation is possible today along the international border as the upper level low moves eastward. Temperatures will cool off into the lower 30s north to lower 40s south as a cooler air mass sags into the Northern Plains. Broad troughing over the Great Lakes will keep the Northern Plains in weak northwesterly flow.
924 AM EST Wed Nov 8 2023 Above normal temperatures will once again be present today as a warm front lifts northward today. A cold front will move through tonight into Thursday. Surface obs indicate that the warm front associated with the low pressure system to our west (currently around the NE/MO border) is currently lifting into our southern CWA. Previous discussion-> Mostly dry conditions are expected today, however a few light isolated showers will be possible as a warm front moves northward. A cold front will move through tonight into Thursday.
Fog has developed this morning in most of the low lying ares and valleys. A short period of high pressure will bring mild weather to the area until the next cold front arrives, Thursday. Model pressure at 500 mb shows the previously persistent trough weakening as it loses the steep gradient and its' axis proceeds to the southeast, relative to PNW. Upstream ridging is settling over the area with skies clearing, other than occasional high cloud groups. Negative vorticity from clockwise curvature of air flow over the ridging, is promoting subsidence. The next cold front is due to arrive by Thursday afternoon, bringing light beneficial rain to the CWA.
Should be a pleasant afternoon with highs in the low/mid 80s. Dry air will remain in place across central Florida today as high pressure dominates the Southeastern U.
401 AM CST Wed Nov 8 2023 - Dense fog across the Highway 183 corridor this morning - Gusty northerly winds through the day (around 35 mph gusts) - Cooler Highs(50s) by Thursday. warming back up above normal through the weekend - Dry though the period Fog development along the leading edge of an advancing cold front this morning is the highest impact weather of the next several days. Gusty north winds Today will bring frequent gusts of around 35 mph and may peak higher as sustained wind speed in the low 20s mph range persist through the day. Box and whisker plot suggest the temps at Elkhart to reach at least 64 degrees and as warm as 67, and farther northeast at Hays, the same considered range of outcomes varies several few degrees cooler - from 60 to 64F.
241 AM PST Wed Nov 8 2023 Cold mornings with below average temperatures will be in place through Thursday before a warmer and dry pattern develops through this Veterans Day weekend. Cooler and below average temperatures will stick with us through Thursday with highs remaining in the lower 50s across western Nevada and upper 40s for Sierra communities. However, some areas in the Sierra Valley and Martis Valley near Truckee could still see freezing fog.
306 AM CST Wed Nov 8 2023 Key Messages: * Cooler and windy today.
316 AM PST Wed Nov 8 2023 Snow showers will end in the higher elevations of the Sierra Nevada this afternoon.
649 AM EST Wed Nov 8 2023 Above normal temperatures will once again be present today as a warm front lifts northward today. A cold front will move through tonight into Thursday. Mostly dry conditions are expected today, however a few light isolated showers will be possible as a warm front moves northward. A cold front will move through tonight into Thursday.
527 AM CST Wed Nov 8 2023 (Today and tonight) Today features an incoming cold front, record heat, and elevated fire weather risk across southwest OK and western north TX. Along with the heat, relative humidity values drop into the low teens over western Oklahoma and western north Texas ahead of the cold front.
Continued dry conditions and mostly clear skies will help lift high temperatures into the low to mid 80s. Daily low-end shower and storm chances exist for Mon-Fri, though confidence remains limited due to the evolution of the potential upper low. The upper low will continue to sluggishly depart up the East Coast through Sunday, with narrow ridging moving over the Ohio Valley through the day.
242 AM EDT Sat Jun 17 2023 High pressure will build down into and over the region for today through Sunday.
Building upper-level ridging will keep skies predominantly sunny but some lingering smoke aloft will keep a slight haze look to the sky. Regardless, temperatures are expected to warm into the low to mid-80s for most this afternoon though a light onshore breeze will keep locations along the shore in the mid-60s to lower 70s. The continued warm advection looks to allow temperatures to still top out in the mid to possibly upper 80s on Sunday for most with areas along the lake front being a tad cooler in the 70s.
Early this morning water vapor imagery shows a mid level trough moving across the Rockies. Further south additional convection continued to fire along within an areas of 925-850mb frontogenetic forcing and within a theta-e ridge and instability axis. Areas of southern Kansas look to have the highest potential for severe storms with wind gusts in excess of 60 mph and large hail overnight. The mid level trough across the Rockies will move across the central Plains tonight and exit on Sunday. Locally heavy rainfall will be possible later tonight as moisture transport increases and a 850-700mb theta-e ridge extends from south central through northeast and east central Kansas. Convection will be on the decrease by late morning Sunday as the mid level trough axis passes.
210 AM MDT Sat Jun 17 2023 Satellite imagery in the early morning hours indicated an upper low along the MT/ND border while a broad cloud shield covered the Pacific NW and was moving into the Idaho panhandle and western Montana. The aforementioned upper low will drift east today while westerly flow develops over our forecast region. On Sunday, the southwesterly flow pattern will still be over our area as a strong upper low settles over the British Columbia coast and our Pacific NW. A powerful 110kt upper jet will nose into central Montana ahead of the upper low.
Lows should be in the 50s to near 60 behind the weak front and in the lower 60s ahead of it. Temperatures will be cooler in most locations as clouds and precipitation keep heating limited. Cooler air will filter in with lows from the mid 50s to lower 60s. Southerly flow and warmer conditions will fill in on Sunday as the wave moves out of the area.
(Today through Sunday) Unseasonably hot temperatures continue today through Sunday thanks to lower to mid level thermal ridging and a Subtropical Ridge centered just south of our area over northeastern Mexico. High temperatures today may be slightly "cooler" than yesterday due to cirrus overhead. Subsidence and a capping inversion underneath the Subtropical Ridge will continue a rain free forecast for most areas through Sunday.
A bit warmer readings expected in the east overnight as more clouds and shower activity linger. The first part of the weekend looks to feature more clouds in our eastern zones which could perhaps keep temperatures a bit cooler. More sunshine is expected farther west on Saturday with slightly warmer afternoon temperatures around 80 degrees. For Mon-Wed heights will build strongly across the Northern Plains as an upper trof digs into the PacNW. The building thermal ridge out ahead of the northwestern trof will allow for a capping elevated mixed layer to advect northeast across the forecast area.
307 AM EDT Sat Jun 17 2023 Dry weather continues today and tonight as high pressure at the surface and aloft controls the region. In addition, the overall haze from wildfire smoke won't be quite as prevalent as yesterday, and that may also contribute to slightly warmer temps today.
257 AM EDT Sat Jun 17 2023 Water vapor imagery and RAP analysis show a mid-level ridge extending from the Upper Mississippi Valley to eastern Hudson Bay. At the sfc, associated high pres ridge extends from IL across Upper MI to James Bay. Ridging from the mid-levels down to the sfc will prevail today.
Tomorrow will consist of dry and warm conditions as a cold front settles in from the north. All eyes are on Sunday as the aforementioned cold front stalls and will resume the unsettled weather pattern. Sunday will bring a chance of severe storms to most of the Midsouth, ahead of a low pressure trough lifting out of the Great Plains.
127 AM EDT Sat Jun 17 2023 Aviation High pressure situated over the Western Great Lakes will bring fair weather both tonight and on Saturday. High pressure at the surface and aloft will result in clear skies tonight and Saturday. Highs Saturday will climb to around 80 as temperatures continue their slow moderation under the ridge. Lows Saturday night will be a few degrees warmer than tonight. Another blocking pattern is taking shape, and we will once again be on the warm and dry portion of the block.
With an upper level ridge axis building into the Central Great Lakes over the Weekend, there does not look to be a whole lot of concern with cloud cover with the general subsidence regime and mean 1000- 500 MB RH mainly under 40 percent. A strong upper level ridge center will then build over/around Lake Superiors by mid week, with 500 MB heights in excess of 590 DAM.
This trough and daytime heating will allow for brief showers and thunderstorms to move through the area, especially along and west of HWY 24.
145 AM EDT Sat Jun 17 2023 A cold front will push across the area this evening into tonight, with dry conditions and high pressure expected behind it for Saturday and Sunday. After that, a cold front sweeps through and offshore of the local area tonight. High pressure will build down into and over the region for Sat through Sun, providing dry/mostly sunny or sunny conditions. Highs in the lower to mid 80s Sat. Warmer on Sun, with highs in the mid 80s to near 90 inland/Piedmont, and lower 80s at the coast.
Low pressure will develop across the region and prevail through the early and middle part of the week. Early this morning: Surface analysis shows that the upstream cold front is just starting to cross the NC/SC state line and continues to make southward progress. That, in combination with possible outflow from the convection moving out of the Gulf Coast states will probably kick off some showers and thunderstorms during the afternoon, with the higher precip probs across southeast Georgia.
We've also been watching remnants of a cold front across the southern Big Country, with some large temperature differences today across the front.
Mid level ridge will build through the wrn lakes this period assuring dry weather and warming temps.
Forecast highs are in the mid to upper 60s for most of the forecast area, with the exception of the far northwest and far southeast in the lower to mid 70s.
Tonight into Saturday morning the mid-level ridge axis will gradually shift east of the area due to a progressive mid-level trough deepening across the Northern Rockies and High Plains and extending into the Central Plains. This advancing trough will help to push a surface cold front eastward across the CWA Saturday night into Sunday. By Sunday, anticipate slightly cooler conditions with highs in the low/mid 80s.
1209 AM CDT Sat Jun 17 2023 (This evening through Saturday) Our area will remain under upper-level ridging this evening which will keep us capped today. This convectively reinforced cold front should dive into the far southern Texas Panhandle by Saturday morning. Temperatures will also be much warmer tomorrow with high temperatures in the mid to upper 90s.
Indiana finds itself within weak ridging associated with the northern branch, while to our south the more zonal southern branch skirts across the Gulf Coast. Simultaneously, ridging looks to build over the Great Plains before extending northeastward. By mid week, the main axis of ridging will be to our north over the Great Lakes. With a greater influence from the ridging our weather may be largely quiet with near to above- average temperatures. Beyond the long range period, there is some hints in guidance that the ridge may retreat westward a bit. Given the complicated flow pattern and potential blocking.
324 AM CDT Sat Jun 17 2023 A broad upper trough will keep temperatures cooler today with highs around normal or even a few degrees below normal. Southerly sfc winds ahead of an approaching low pressure system will help draw up warmer air on Sunday, pushing highs into the 80s to near 90 degrees.
(Today through Sunday) The overall synoptic pattern should remain the same through the short term period with the region staying in northwesterly flow on the northeast side of a ~595dam ridge centered just south of Brownsville, TX. With the higher thicknesses and heights, temperatures today will continue to be very warm.
349 AM EDT Sat Jun 17 2023 High pressure will build down into and over the region for today through Sunday.
Warmer and mostly dry next work week. Look for a cooler day with highs in the low 80s. A building ridge will lead to mostly dry conditions and highs in the upper 80s to low 90s for much of next work week.
Lows will dip into the mid to upper 50s across the area, with some locations in Minnesota Lakes country getting to the low 60s.
406 AM EDT Sat Jun 17 2023 High pressure will build down into and over the region for today through Sunday.
954 AM CDT Sat Jun 17 2023 (Issued 954 AM CDT Sat Jun 17 2023) High pressure to the east will continue to bring quiet weather today and tonight. Highs should reach the lower 80s well inland, with 70s near the lake.
717 AM CDT Sat Jun 17 2023 (Today through Sunday) In the lower levels, we have a tale of two boundaries with a stationary boundary from W-E across the Gulf Coast and a cold front to our N trying to push SSW into AL today. Although the cold front may make some brief progress into the NE counties, for the most part C AL remains in an unsettled pattern. In the upper levels, a low is situated from Quebec to NY while an upper ridge is present over Mexico, TX, and the W Gulf. Now through Sunday, the upper ridge will stay persistent over the same region. At the same time the upper low will cycle to the NE toward Nova Scotia. Will continue with a mention of strong to severe thunderstorms with this high shear/high cape environment.
Any storms that form are progged to dissipate by midnight as a cold front pushes south into the forecast area, however, it won't mean much outside a wind shift out of the NE, as temps and dewpoints will remain roughly the same on either side of the meek frontal zone.
A breezy southwesterly to westerly gradient continues over the area, with a trough to our north and strong high pressure over eastern to central Mexico. the resulting flow is largely dry in the lower levels, however a fetch of mid and upper level moisture wrapping around the western flank of the high brings some clouds into Sonora and SE AZ at times. Not a lot of depth with little sustainable support, so as the high center reconsolidates over northwest Mexico, this will probably shut back down.
A cold front moves through the region tomorrow bringing cooler temperatures.
716 AM EDT Sat Jun 17 2023 A much drier and somewhat cooler northerly flow in the wake of surface and upper level low pressure over the New England states will bring us morning clouds then increasing afternoon sunshine today. Sunday will feature slightly warmer temperatures with continued comfortable humidity. Weak ridging aloft and the subsiding, thermally indirect, right exit region of a speed max diving SE from Lake Ontario and the Finger Lakes region of upstate New York will negate anything more than a few isolated showers NE of the KIPT area.
Dry weather continues today and tonight as high pressure at the surface and aloft controls the region. In addition, the overall haze from wildfire smoke won't be quite as prevalent as yesterday, and that may also contribute to slightly warmer temps today.
In this case, with the 500 mb ridge parked over the western part of state, we will again experience temperatures and dewpoints that will push our heat indices over 115F for most of the forecast area, except the coastal zones.
Afternoon highs across the region will top out in the upper 80s along the coast and into the lower 90s inland.
(Rest of Today) Weak frontal boundary is located along the AL/TN state border this Sat morning, as temps begin to rebound into the 70s from their earlier lows in the lower/mid 60s.
624 AM CDT Sat Jun 17 2023 An upper level ridge of high pressure will bring mostly sunny skies and slightly above normal temperatures to the Midsouth this afternoon. The fair weather will be short-lived, however, as the upper level ridge lifts off to the east tonight. Widespread showers and thunderstorms will develop Sunday, in advance of an upper level low pressure system lifting out of the Great Plains.

The radar is currently clear right now as flat ridging has moved over the area.
(Today through Sunday) In the lower levels, we have a tale of two boundaries with a stationary boundary from W-E across the Gulf Coast and a cold front to our N trying to push SSW into AL today. Although the cold front may make some brief progress into the NE counties, for the most part C AL remains in an unsettled pattern.

Will continue with a mention of strong to severe thunderstorms with this high shear/high cape environment.
1021 AM EDT Sat Jun 17 2023 High pressure centered near Chicago will continue to provide us with a pleasant summer day today with a light east/northeast breeze and afternoon temperatures in the lower and middle 80s. Dry weather continues today and tonight as high pressure at the surface and aloft controls the region. In addition, the overall haze from wildfire smoke won't be quite as prevalent as yesterday, and that may also contribute to slightly warmer temps today.
1054 AM EDT Sat Jun 17 2023 A much drier and somewhat cooler northerly flow in the wake of surface and upper level low pressure over the New England states will bring us morning clouds then increasing afternoon sunshine today. Sunday will feature slightly warmer temperatures with continued comfortable humidity. Weak ridging aloft and the subsiding, thermally indirect, right exit region of a speed max diving SE from Lake Ontario and the Finger Lakes region of upstate New York will negate anything more than a few isolated showers NE of the KIPT area.
620 AM CDT Sat Jun 17 2023 A broad upper trough will keep temperatures cooler today with highs around normal or even a few degrees below normal. Southerly sfc winds ahead of an approaching low pressure system will help draw up warmer air on Sunday, pushing highs into the 80s to near 90 degrees.

632 AM CDT Sat Jun 17 2023 (Today through Sunday) The overall synoptic pattern should remain the same through the short term period with the region staying in northwesterly flow on the northeast side of a ~595dam ridge centered just south of Brownsville, TX. With the higher thicknesses and heights, temperatures today will continue to be very warm.
623 AM CDT Sat Jun 17 2023 (Today through Sunday) Unseasonably hot temperatures continue today through Sunday thanks to lower to mid level thermal ridging and a Subtropical Ridge centered just south of our area over northeastern Mexico. High temperatures today may be slightly "cooler" than yesterday due to cirrus overhead. Subsidence and a capping inversion underneath the Subtropical Ridge will continue a rain free forecast for most areas through Sunday.
Dry weather returns early this upcoming workweek with significantly warmer high temps in the 80s and a few 90s. Conditions have been fairly quiet this morning as ridging continues.
