1036 PM EDT Tue Oct 1 2024 A weak cold front will move offshore by tonight. Northeasterly winds with near normal temperatures will develop for the remainder of the week as high pressure builds in from the north. Cooler temps behind the front have compressed the boundary layer and low level cloud cover is increasing from NW to SE. Cooler tonight behind the front and with lows in the mid and upper 60s. Given the low cloud decks, expect at least some isolated patches of fog, primarily inland. Highs in the lower 80s with drier air and dew points back in the low to mid 60s. Quiet period weather-wise as high pressure ridges down from the north behind a cold front.
956 PM EDT Tue Oct 1 2024 - Patchy frost possible across interior low-lying areas tonight - Cooler, but near-average temperatures through the end of the week. Definitely looking at lows dropping into the 30s across a good portion of the interior, with readings remaining a bit "warmer" near those big waters. Forecast Details: Patchy frost possible tonight -- With aforementioned high pressure building in behind the front, skies are expected to continue to clear with winds going weak/calm tonight. Localized interior low-lying areas may dip into the low/mid 30s, where patchy frost development will be possible. Pattern Synopsis and Forecast: Upper-level longwave troughing will support relatively quiet weather through the period with occasional chances for precipitation through the weekend.
620 PM CDT Tue Oct 1 2024 - Cooler conditions will occur the rest of today into Wednesday along with dry conditions.
502 PM EDT Tue Oct 1 2024 - Showers will affect the area at times until a cold front passes through eastern Kentucky tonight.
Skies being clear to partly cloudy will allow low temperatures to dip into the upper 30s across Central Lower Michigan and the lower 40s across. Winds become southwesterly on Wed and the cooler 850 mb temperatures will be advected away.
608 PM CDT Tue Oct 1 2024 Updated at 535 PM CDT Tue Oct 1 2024 - Cooler tonight behind this mornings cold front passage.
616 PM CDT Tue Oct 1 2024 - Brief Period of Cooler Conditions - Warmer By End of the Week - Mostly Dry Conditions Next 7 Days Surface cold front has cleared the area and has provided Autumn like conditions across the area. General H5 ridging expected to remain in place across the western third of the CONUS, promoting weak zonal flow across our region. Strong AVA regime and subsidence will allow a prominent surface anticyclone to slowly meander the central CONUS through much of this week, with the center crossing into the lower Missouri River Valley sometime Wednesday morning into afternoon.
745 PM EDT Tue Oct 1 2024 Slow moving low pressure system will continue to push east into the Atlantic this afternoon. A frontal boundary will move east from the Ohio Valley on Wednesday and drier air will filter into the region through the end of the week as high pressure begins to build in overhead. High pressure wedging in from the NE behind this trough and the departure of the short wave in the next couple of hours should bring an end to the heavier showers. Upper low will finally begin to kick east into the Atlantic by tonight.
Catching up rather quickly is the cold front arriving in CLE right now (0030Z). Slowly departing upper low circulation combined with continued moist southeast upslope flow will cause thick clouds and light rain/drizzle to linger overnight throughout central Pennsylvania. Low clouds/fog will reduce the visibility on the ridgetops AOA approx 1800 ft MSL. A cold front moves through and washes out over central PA by midday on Wednesday and fails to scour out the low level moisture. Highs will be in the lower 60s in the Northern Mountains and Laurel Highlands, mid 60s in central PA and upper 60s in the Susquehanna Valley. Lows will be in the lower 40s in the Northern Mountains, upper 40s and lower 50s in central PA, and upper 50s in the Susquehanna Valley.
618 PM CDT Tue Oct 1 2024 (This evening through Wednesday Night) Warm and quiet conditions will persist through the next couple of days as a dry E/NE flow continues in response to high pressure lin- gering over Middle MS River Valley. Highs tomorrow will peak in the lower 90s at most locations. a bit cooler along the coast (in the mid to upper 80s).
Dry cold front will pass through overnight and Wednesday morning.
611 PM CDT Tue Oct 1 2024 - A dry cold front will move through the Northland preceded by gusty winds on Wednesday. - High pressure and cooler temperatures for the rest of the work week. Tonight, the cold air mass that kept us cool today will move off to the east and warmer temperatures will return on Wednesday. Highs will be in the low 70s for most, with areas near the Canadian border remaining in the upper 60s. Gusty southerly to southwesterly winds will pick up overnight ahead of a dry cold front moving northwest to southeast Wednesday afternoon and evening.
705 PM EDT Tue Oct 1 2024 High pressure continues dry weather today into Wednesday. A moisture starved cold front will cross the region Wednesday night with little in the way of precipitation.
954 PM CDT Tue Oct 1 2024 Updated at 916 PM CDT Tue Oct 1 2024 - Cooler tonight behind this mornings cold front passage.
545 PM CDT Tue Oct 1 2024 (Through Tonight) The cold front has pushed through the forecast area, with the highest wind gusts actively trending downward across northeast Oklahoma.
1026 PM EDT Tue Oct 1 2024 High pressure continues dry weather today into Wednesday. A moisture starved cold front will cross the region Wednesday night with little in the way of precipitation.
531 PM EDT Tue Oct 1 2024 High pressure will stay in the forecast region until Wednesday evening, when a cold front begins to move through the northeast. This should cause lows to be in the low-to-mid 40s throughout the area. Wednesday will continue to see some cloud cover throughout the day, with highs generally in the low 60s. Winds will become south/southeasterly, providing some moisture in the lower levels, as the high pressure to the east moves away as a weak cold front approaches from the west.
725 PM EDT Tue Oct 1 2024 A weak cold front will move offshore by tonight. Northeasterly winds with near normal temperatures will develop for the remainder of the week as high pressure builds in from the north. Cooler temps behind the front have compressed the boundary layer and low level cloud cover is increasing from NW to SE. Cooler tonight behind the front and with lows in the mid and upper 60s. Given the low cloud decks, expect at least some isolated patches of fog, primarily inland. Highs in the lower 80s with drier air and dew points back in the low to mid 60s. Quiet period weather-wise as high pressure ridges down from the north behind a cold front.
734 PM EDT Tue Oct 1 2024 An upper level trough axis will be north of the area today with isolated showers possible.
944 PM EDT Tue Oct 1 2024 High pressure will stay in the forecast region until Wednesday evening, when a cold front begins to move through the northeast. This should cause lows to be in the low-to-mid 40s throughout the area. Wednesday will continue to see some cloud cover throughout the day, with highs generally in the low 60s. Winds will become south/southeasterly, providing some moisture in the lower levels, as the high pressure to the east moves away as a weak cold front approaches from the west.
729 PM CDT Tue Oct 1 2024 - Some of the coolest air of the season is on tap overnight, with widespread lows in the lower 40s.
958 PM EDT Tue Oct 1 2024 A cold front will push through this evening with scattered showers and gusty winds. A dry weather pattern is forecast to return for the remainder of this week as high pressure builds across the country. Cold front continues to work its way through our CWA through the overnight hours. High pressure will be positioned over the Ohio Valley through the short term.
The possible negative factor to fog is high pressure over the MO Valley building east, producing a bit of a pressure gradient across KY/TN.
1242 AM CDT Wed Oct 2 2024 (Tonight) A weak cold front located from mid TN SW into NW MS continues to drift SE closer to NW AL this Tue evening. The front will nudge into the area later tonight, with slightly cooler/drier air in tow. With the influx of cooler air, lows into early Wed look to fall into the lower 60s/near 60F.
High pressure will keep well-above normal temperatures around for the foreseeable future. Temperatures continue to remain around 10-20 degrees above the seasonal averages as high pressure continues to keep a hold on the region. Some isolated showers may develop again on Wednesday and looks to be mainly confined to the higher elevations along the Rim. From Thursday onward, high pressure remains locked in place leading to a continuation of abnormally hot weather with no chances for precipitation.
A dry cold front is moving across Western Montana this early morning.
(Today through Thursday) A wind shift associated with a weak cold front is evident as a fine line on radar moving southeastward this morning. The lower dew points and cold air advection are lagging behind the front, however. With ridging building aloft and less cloudcover than previous days, high temperatures will continue to trend upward. The front will stall out and become diffuse with time, and winds will begin to shift to easterly tonight as high pressure reaches the Mid-Atlantic. This will keep low temperatures on the mild side in the southeast counties, but the typically cool spots in the far north will drop into the 50s near the lower dew points. Flow aloft will become southerly to southwesterly on Thursday as ridging builds over Georgia and the Carolinas while a weak southern stream trough develops over the ArkLaTex.
203 AM CDT Wed Oct 2 2024 - While a series of cold fronts will move through the region through the weekend, at or above average temperatures are expected to prevail. While light winds and very dry airmass associated with this high will foster a chilly start to day, a high-level deck of cirrus overhead is likely to keep early morning lows a couple of degrees warmer than previously though. This will allow a warmer airmass to work back northward into the region today and especially by Thursday. Accordingly, expect high temperatures to rebound back into the lower 70s this afternoon under mainly sunny skies. A weak surface cold front will be approaching the WI state line later in the day.
Pattern Synopsis/Forecast: Upper-level troughing situated over Hudson Bay at this early hour with troughing draped across north- central Canada. At the surface, high pressure centered over the mid- Mississippi Valley will gradually drift east. Longwave midlevel troughing is currently spanned across the northern half of North America with large scale low pressure over Hudson Bay. Aformentioned troughing will begin to push a cool continental air mass into the Great Lakes region for the entirety of the forecast period.
A mid-level ridge across the southwest U. will expand eastward into the Southern Plains in tandem with a low-level thermal ridge and a return to southerly winds.
154 AM EDT Wed Oct 2 2024 A cold front will push through this evening with scattered showers and gusty winds. A dry weather pattern is forecast to return for the remainder of this week as high pressure builds across the country. Cold front continues to work its way through our CWA through the overnight hours. High pressure will be positioned over the Ohio Valley through the short term.
/EC/ The forecast remains on track, with a ridge building into the area and clearing skies and allowing for some more sunshine.
138 AM CDT Wed Oct 2 2024 The forecast remains on track, with a ridge building into the area and clearing skies and allowing for some more sunshine.
331 AM EDT Wed Oct 2 2024 High pressure shifts east this morning as a cold front approaches from the west.
107 AM EDT Wed Oct 2 2024 A weak surface front/trough is moving toward the forecast area tonight and triggering a few more showers across southwest Virginia and northeast Tennessee. The possible negative factor to fog is high pressure over the MO Valley building east, producing a bit of a pressure gradient across KY/TN.
Ridging over the Eastern Pacific will remain over CA through today before it shifts into the southwest US as troughing extends from the Pacific NW and a secondary trough off the far southern CA coast Thursday afternoon. The trough passing through the Pacific NW will help flatten the ridge briefly but high pressure resurges over the area this weekend.
1221 AM CDT Wed Oct 2 2024 (Tonight through Wednesday night) While areas over land will mostly stay dry, the tail end of a trough will move across the Gulf waters and South Texas tonight leading to a low to medium (15-35%) chance of rain over the waters where moisture is closer to normal (1.
320 AM EDT Wed Oct 2 2024 A weak cold front crosses the area today with dry high pressure filtering into the region behind it on Thursday.
(Today and tonight) Not much in the way of change to report for the short-term forecast as upper level ridging will remain well in place over the Southern Plains today. Winds veering more to the south will allow low level moisture to slowly start making its way back into the region which will help to keep overnight lows a touch warmer than the past few nights in the low to mid 60s.
Still some lingering influence from nearby surface ridging over in western AR tonight, with light and variable wind allowing temps to drop more than blended guidance indicates.
Already sunny areas west of the Plateau will reach the lower 80s. Clouds will build up again and there will be a few scattered showers this afternoon and early evening as a cold front pushes into the area.
1254 AM CDT Wed Oct 2 2024 Another pleasant early fall evening is underway with mostly clear skies and 9 PM temperatures ranging through the 70s as a weak cold front advances toward the I-30 corridor. May not be noticeable at first, but a cold front is slowly working into region, and will continue pushing south during the late evening and overnight hours. Warmer temperatures will prevail temporarily through D4-6 of the forecast period, along with some rain chances in the mix.
1207 AM CDT Wed Oct 2 2024 (Tonight through Wednesday night) A positive tilted mid/upper trough axis stretching from the Carolinas to East TX will continue moving southward overnight. The tail end of this trough axis will impinge upon our CWA by Wed morning and help to advect higher moisture mainly in the lower to mid levels.
(Today through Thursday) The upper trough associated with the subtrop jet is moving east of the area while looking upstream the upper stacked high currently centered over Chihuahua, Mexico(best seen in WV imagery) will get squeezed by the zonal upper trough found from southern Cali through northern TX. As this weak trough begins to stand(become meridional) it will begin to draw gulf moisture northward. But this rain will struggle to get far inland Thu, but this may be a bit different Fri as there should be a fair amount of forcing northward ahead of the upper trough that will be near the TX coast. We will continue to see disturbances flare up on this TUTT low's east and south side and as the low moves west and dissipates, it will open things up a bit more.
Dry conditions will be seen tonight and Wednesday as high pressure quickly moves through the area. Return flow developing late tonight and Wednesday will bring windy and warmer temperatures to the area. The warmer and windy conditions will bring an elevated fire risk Wednesday. The higher fire risk is west of the Mississippi where temperatures and winds will be warmest/highest. The possibility does exist that high temperatures Wednesday could be warmer than forecast.
312 AM EDT Wed Oct 2 2024 High pressure will work into the region and allow for several days of quiet weather.
1118 PM CDT Tue Oct 1 2024 (Tonight through Thursday night) Wx map shows high pressure gradually filtering south, keeping northeast winds across the region. The stronger cold front extends across North Texas into Oklahoma and Arkansas, with the more noticeable cooler air behind this. Wednesday, the mid to upper level flow will remain weak with a mid to upper level trough being more pronounced over Texas by Thursday.
1123 PM EDT Tue Oct 1 2024 High pressure will stay in the forecast region until Wednesday evening, when a cold front begins to move through the northeast. This should cause lows to be in the low-to-mid 40s throughout the area. Wednesday will continue to see some cloud cover throughout the day, with highs generally in the low 60s. Winds will become south/southeasterly, providing some moisture in the lower levels, as the high pressure to the east moves away as a weak cold front approaches from the west.
1143 PM CDT Tue Oct 1 2024 - An isolated shower chance lingers in the east as a cold front completes its passage. - Cooler/drier air comes in behind the front for the mid week, then we warm back into the 80s for the week's end. - Another dry cold front's passage late this weekend will cool us back into the lower 70s again for early next work week. A cold front is making passage.
410 AM EDT Wed Oct 2 2024 An upper level trough axis will be north of the area today with isolated showers possible.
Plenty of low level moisture under an inversion will allow for stratus/fog to be an issue at times, but will see things improve toward late morning as a front moves in mixing out the low levels. Models are favoring a few showers with the front with a better coverage closer to the upper support over the Blue Ridge north of Peaks of Otter, east to the central VA piedmont. Lows will be cooler but still above normal from the upper 40s to mid 50s west, to around 60 east. High pressure will build into the area from the north Thursday.
1205 AM CDT Wed Oct 2 2024 (This afternoon through Wednesday night) There continues to be little in the way of meaningful weather change over the next 36 to 48 hours as a large upper-level high pressure remains nearly stationary near the Four Corners through the period. Despite this, a weak cold front moved through the region this morning, bringing a breezy north wind and slightly cooler temperatures with it. Much of the area can expect temperatures nearly 5 degrees cooler than yesterday as widespread middle 80s are likely this afternoon. While cooler, these temperatures remain just a touch above normal.
129 AM EDT Wed Oct 2 2024 * Cooler tonight with lows in the 40s. Cold front near the I-69 corridor (as of 18z) will continue to progress east through the remainder of the forecast area this afternoon. Good post-frontal cooling (850mb temps dropping 8C or so) will allow for a few gusts to exceed 20 knots behind the cold front from west to east into the early evening. High pressure does fold in overnight into Wednesday with clear skies and light winds.
140 AM CDT Wed Oct 2 2024 - High confidence for dry weather pattern persisting for several days along with warmer than normal temperatures Warmer temperatures will return to the region today and especially on Thursday with 90s coming back into the forecast. In the wake of each upper level wave racing east across the northern plains into the Great Lakes a couple cold fronts will move southward into Kansas.
Plenty of low level moisture under an inversion will allow for stratus/fog to be an issue at times, but will see things improve toward late morning as a front moves in mixing out the low levels. Models are favoring a few showers with the front with a better coverage closer to the upper support over the Blue Ridge north of Peaks of Otter, east to the central VA piedmont. Lows will be cooler but still above normal from the upper 40s to mid 50s west, to around 60 east.
Record high temperatures and dry weather will continue through the week as a strong area of high pressure remains parked over the Desert Southwest. Forecast thinking has also changed little, as high pressure remains locked in place for a bit longer, resulting in unseasonably hot temperatures.
218 AM EDT Wed Oct 2 2024 An upper level trough axis will be north of the area today with isolated showers possible.
(Today and tonight) The flow over North America has become more zonal with a flat ridge extending from California to East Texas and eastern Oklahoma. This ridge will expand eastward along the Gulf Coast while a weakness develops in it over the southern High Plains. Low level warm advection will result in temperatures warming back into the upper 80s to lower 90s, in line with conditions before yesterday's cold front. Surface winds are likely to remain closer to 10 mph overnight which will help lead to a relatively mild night and low temperatures near 5 degrees warmer than normal.
1120 PM EDT Tue Oct 1 2024 A weak cold front crosses the region on Wednesday with dry high pressure building in behind it on Thursday.
358 AM EDT Wed Oct 2 2024 A weak cold front will bring scattered showers to the region today. Ahead of an approaching cold front, a weak wave will pass through the region early this morning and support scattered showers over portions of the region. The cold front is just now entering western NY and PA. High pressure builds into the region tonight and bring drier conditions. Broad upper-level ridging will build just off the coast on Thursday. Flow also becomes southwesterly, which will advect in warmer air to replace the departure of the cooler airmass left behind by the cold front.
A dry cold front will arrive late this afternoon and this evening. Temperatures on Thursday look about 5 to 10 degrees cooler than today.
Additionally, an upper-level ridge extending from the Pacific Ocean through the southwest CONUS across the northern gulf coast will maintain dry conditions areawide through the period. With a cooler airmass in place, high temperatures will range from the lower 80s across southwest Arkansas to the upper 80s across Deep East Texas this afternoon. /05/ (Thursday Night through Wednesday) The upper-level ridge across the region to be split by a deepening low across south Texas and Mexico by Thursday night.
134 AM EDT Wed Oct 2 2024 A weak cold front crosses the area today with dry high pressure filtering into the region behind it on Thursday.
1226 AM CDT Wed Oct 2 2024 (This evening through Wednesday) A cold front moved through our area this morning and is well south of our area per the latest surface observations. Breezy and slightly cooler conditions persisted behind this frontal boundary, which will limit today's high temperatures. Warmer temperatures should ensue for tomorrow as winds will veer and become southwesterly.
The way the sfc pressure gradient orientation lays out will produce the higher wind gusts acrs the northwestern half of the DVN CWA this afternoon, thus the higher fire danger will be acrs eastern IA along and north of the I80 corridor.
Record high temperatures and dry weather will continue through the week as a strong area of high pressure remains parked over the Desert Southwest. Desert Rock-Mercury: 103 (formerly 100 in 1980) Kingman: 102 (formerly 99 in 2020 and 1980) Barstow-Daggett: 108 (formerly 105 in 1980) Needles: 112 (formerly 108 in 2020 and 1978) Death Valley: 114 (formerly 113 in 2003 and 2001) The heat will continue as the region sits beneath a ridge of high pressure through the remainder of the week. Overnight temperatures have been trending cooler than forecast, so the Excessive Heat Warning for the Las Vegas Valley and Moapa Valley have been allowed to expire on time this evening, as overnight lows effectively cool off the region and give bodies a chance to recover before the heat of the next day.
Cooler for Wednesday, then mild but still dry for Thursday.
(Through Wednesday) Upper level trough pivots through the area this afternoon and into the overnight hours. Mostly clear skies are expected on Wednesday and with no cooler airmass behind the front, expect temps near 90s. (Wednesday night through Thursday night) A subtropical upper level ridge expanding from the Atlantic will pull in moisture from the south/southwest in the upper levels. Temperatures will be in the upper 80s to low 90s, with the heat index in the low to mid-90s. Expect overnight lows to be in the upper 60s warming to the low 70s by Thursday night.
