On Sunday, we do expect a cold front to move into the region during the afternoon. As mentioned above, a cold front will move in, bringing a northerly wind shift during the late afternoon and evening hours. Low temperatures Sunday night will be a little cooler compared to tonight, with lows generally in the 50s.
Trough will rotate south and east through the Midwest and Ohio Valley. Associated cold frontal system will push across the Ohio Valley by late in the day on Sunday. A series of ridges of high pressure will keep the weather across eastern Kentucky dry through the end of the week.
/issued 808 AM EDT Sat Oct 3 2020/ This morning a jet streak was across north FL and south GA while mid level troughing stretched down the eastern states and into the Gulf of Mexico. Mid level ridging from the Atlantic extended across the Bahamas to Cuba. It meanders there until this afternoon or evening when it merges with a north bound warm front exiting south FL.
A dry cold front will move through the area Sunday night. High pressure centered over the Ohio Valley ridging into the Carolinas and GA. Dry weather will continue this afternoon with high temperatures in the low and middle 70s. Sunday and Sunday Night: A deep upper trough will be in place over the Great Lakes region and Ohio Valley on Sunday. Highs should be in the lower 70s, possibly a bit cooler over the eastern Midlands due to the more extensive cloud cover. The upper trough will shift eastward into the Mid-Atlantic region Sunday night, pushing the coastal front back offshore, and all of the associated moisture with it. Skies will gradually clear though the night, with lows in the lower and mid 50s.
400 PM EDT Sat Oct 3 2020 Rain is likely tonight into Sunday as a low pressure system moves through the area.
/EC/ The forecast is on track in the near term with high pressure in control of the weather over the ArkLaMiss region.
A cold front has moved past all three terminals. /issued 151 AM CDT Sat Oct 3 2020/ Early morning water vapor showing today's cold front just through CO and headed southward towards the CWA. A bit of moisture tries to sneak into the lower levels of the atmosphere with the front, but the stable northwest flow aloft will keep the moisture from developing into anything but clouds. High amplitude ridge starts to flatten as zonal flow becomes established across the Pacific NW and southwestern Canada on Sunday.
130 PM EDT Sat Oct 3 2020 Dry today under high pressure. Rain chances will return later on Sunday with the approach of a cold front. Increasing deep layer moisture and ascent ahead of the trough/low should result in the development of scattered showers Sunday and Sunday night.
Cooler temperatures are still forecast on either side of the Valley. Winds are generally light and out of the north, with temperatures in the lower to middle 40s for all but northwest Minnesota, where we are seeing middle to upper 30s. expecting clouds to break up quicker than guidance has been suggesting and allowing temps to get a few deg warmer than previously thought. a few deg warmer in the northeast where it is already clear. Skies clear tonight allowing temperatures to fall back into the upper 20s to low 30s with most areas below freezing.
201 PM CDT Sat Oct 3 2020 Early afternoon analysis showed an upper level trough axis sliding through the forecast area, with associated PV advection leading to some precip. Once the showers exit, guidance suggests at least some clearing takes place across the forecast area as high pressure builds in, and this looks to be supported by upstream satellite imagery. This should set the stage for yet another chilly night with some frost/freezing as temperatures dip in to the upper 20s to mid 30s. For Sunday, high pressure will lead to a sunny and quiet, but cool day across the region.
1105 AM EDT Sat Oct 3 2020 High pressure will keep cool and dry conditions through the weekend.
Only area of concern is a wind shift towards the tail end of this TAF cycle with an approaching cold front and in increase in cloud cover with the lowest ceilings near 5kft or so advancing into our airspace from the northwest near or after sunrise on Sunday.
Weather related impacts will be minimal tonight into Sunday, and will be limited to widespread sub-freezing temperatures across the region.
Tomorrow looks to be cool but otherwise pleasant, with highs in the low 50s. Those clouds should rapidly dissipate with sunset, setting the stage for a widespread frost across the entire area as temperatures settle into the low to mid 30s.
Winds are generally light and out of the north, with temperatures in the lower to middle 40s for all but northwest Minnesota, where we are seeing middle to upper 30s. expecting clouds to break up quicker than guidance has been suggesting and allowing temps to get a few deg warmer than previously thought. a few deg warmer in the northeast where it is already clear.

127 PM EDT Sat Oct 3 2020 High pressure will keep cool and dry conditions through the weekend.
346 PM EDT Sat Oct 3 2020 High pressure will remain in control through Sunday. A cold front will cross the area late Sunday night.
256 PM CDT Sat Oct 3 2020 Tonight through Sunday: An eastern CONUS longwave trough will continue to bring dry weather with seasonable temperatures as we finish up the weekend. For Sunday, the moisture-starved trough will cross the ArkLaMiss region and bring little change in the weather for the forecast area. However with a high pressure driving much of the western half of the state and the atmosphere pattern, we won't see hardly any increase in moisture, leaving us dry with normal like October values for the week.
Cold front will cross NW to SE overnight, bringing an increase in cloud cover and scattered SHRA.
An upper ridge to the west of the CWA will slowly move east across the area during the week while weakening somewhat. Cooler temperatures, lighter winds and higher humidities will reduce the fire danger this afternoon.
432 PM EDT Sat Oct 3 2020 Dry today under high pressure. Rain chances will return later on Sunday with the approach of a cold front. Increasing deep layer moisture and ascent ahead of the trough/low should result in the development of scattered showers, with best chances along the passing sfc cold front.
330 PM EDT Sat Oct 3 2020 High pressure will build into the region from the west tonight and slowly move east of the area by Sunday night.
A stationary boundary across central Florida continues to move northward, associated with the general movement of the cold front that passed over our region yesterday during the early morning hours. High temperatures are forecast to be in the low to mid 70s with lows in the mid 50s to low 60s.
258 PM EDT Sat Oct 3 2020 A deep, southeasterly flow has set up across the Florida Keys and adjacent coastal waters, between Tropical Storm Gamma over the Yucatan Peninsula and a narrow, but deep ridge extending from the Bahamas northeastward over the western North Atlantic. Our colleagues at the Hurricane Specialist Unit of the National Hurricane Center have indicated that this system has a 60 percent chance of organizing into a tropical cyclone during the next five days.
A cold front will move through tomorrow, with winds becoming northerly at AUS around 22Z. Upper level westerly flow across the area will become northerly on Sunday as another upper level trough swings east across the central plains and into the Ohio valley and upper level high pressure remains in place across the western U. At the surface a weak cold front will move into south central Texas on Sunday. This will lead to slightly warmer low temperatures Sunday morning.
1245 PM EDT Sat Oct 3 2020 High pressure will keep cool and dry conditions through the weekend.
A cold front will swing through the area later tonight into early tomorrow morning from the north.
High pressure situated over the coastal New England region will maintain control of our general weather situation tonight. The above noted clouds will be associated with an area of low pressure now forming along the KS/MO border. This new cyclone will deepen slightly as it moves towards the ENE, reaching northern Ohio towards noon on Sun. Clouds in advance of a cold front trailing south of this low will overspread the region on Sun, with the front itself passing across the forecast area in the afternoon/early evening. High temperatures tomorrow should be a bit warmer, topping out in the mid 70s. Clouds should diminish Sun night as slightly cooler air filters into the Valley and high pressure from southern Canada settles over the Eastern Plains.
154 PM EDT Sat Oct 3 2020 High pressure will bring cool and mainly quiet weather to NY and PA today, though a few lake effect rain showers will continue over upstate NY. A warm front will spread a few light showers across the region Sunday afternoon and evening. Moisture trapped beneath a weak high pressure dome will keep mostly cloudy skies over the region through early afternoon. After a cool start to the day, a warm front will move through NY and PA with isolated to scattered rain showers.
High pressure will then bring a return to mainly dry weather tonight through Sunday morning.
VFR will prevail through the TAF period as high pressure maintains control of the region with light and variable winds.

For Sunday, high pressure will lead to a sunny and quiet, but cool day across the region.
745 PM EDT Sat Oct 3 2020 High pressure builds in tonight before moving east late Sunday.
451 PM MDT Sat Oct 3 2020 Upper level analysis and water vapor imagery show persistent, deep trough centered over the Upper Midwest/Great Lakes slowly pushing eastward. Ridge over the Pacific NW will continue to spread eastward and flatten as it approaches the Northern Plains. Expect warm air advection to begin in earnest overnight tonight resulting in warmer temperatures tomorrow as most areas push back into the 70s.
Tonight through Sunday: An eastern CONUS longwave trough will continue to bring dry weather with seasonable temperatures as we finish up the weekend. For Sunday, the moisture-starved trough will cross the ArkLaMiss region and bring little change in the weather for the forecast area. However with a high pressure driving much of the western half of the state and the atmosphere pattern, we won't see hardly any increase in moisture, leaving us dry with normal like October values for the week.
/NEW/ /Tonight through Sunday Night/ Late afternoon surface analysis shows our cold front extending from just north of Midland to near Wichita Falls to Tulsa. The rest of the week will remain uneventful as an upper ridge translates from the Four Corners region eastward through the Plains.
BT High pressure will prevail over the area into Sunday with warm, dry and breezy conditions expected. Temperatures still will be somewhat of a roller coaster as a a few cold fronts cross the area every couple of days. While these fronts will result in some cooler temperatures and a wind shift, not expecting any precipitation.
Outside of a few spots, most of the lowlands remained socked in throughout the day with little clearing. Upper level trough will move through tonight into Sunday.
The main forecasting concern for tonight will be low-level stratus and fog development along the higher terrain of the Ozark Plateau. As it does, the cold front will push across the region. Per the RAP analysis, visibility will reduce below one mile for the higher terrain areas along the plateau, while some of the SREF/HREF progs are less aggressive on reduced visibility but are equally keen on the extent of low stratus. For Sunday, mid-level heights will hastily increase as the 500-mb trough axis shifts east of the Ozarks. The NBM is suggesting afternoon highs in the lower 60s for Sunday.
635 PM CDT Sat Oct 3 2020 As mid level troughiness pivots southeastward into the Ohio Valley, weak ripples of energy will rotate light precipitation across portions of the region tonight into Sunday morning.
Flood Watch Continues Across Most of East Central Florida This A weak inverted trough exists near to just off the coast, with a warm frontal boundary still expected to lift northward into central Florida before stalling either late tonight or early Sunday. Cloudy conditions will persist overnight, with temperatures remaining in the low to mid 70s.

After these low clouds break up by late Sunday morning, the entire area will experience VFR SKC with north to northeast low level flow as high pressure system builds into the Srn Plains. At the surface, weak low pressure was located over the SW MO Ozarks with a cold front stretching southwest roughly down the I-44 corridor. The latest CAM guidance suggests that the northern band will eventually intensify and produce showers and isolated thunderstorms near or just north of the I-40 corridor this evening, forced by increasing QG and low/mid level cold frontogenetic forcing on the cool side of the surface front.
A dry cold front will move through the area Sunday night. Winds will remain northeasterly at 5 mph or less as high pressure ridges into the area from the north. Sunday and Sunday Night: A deep upper trough will be in place over the Great Lakes region and Ohio Valley on Sunday. Highs should be in the lower 70s, possibly a bit cooler over the eastern Midlands due to the more extensive cloud cover. The upper trough will shift eastward into the Mid-Atlantic region Sunday night, pushing the coastal front back offshore, and all of the associated moisture with it. Skies will gradually clear though the night, with lows in the lower and mid 50s.
1030 PM EDT Sat Oct 3 2020 Currently - A broad lower level trough is in the process of lifting northwest of our area this evening. Lower level moisture associated with the broad trough is also shifting out northwestward of our area taking the large shield of rain with embedded showers and thunderstorms with it. Short Term Update - As the trough leaves our area, the Keys will be in a tightening pressure gradient between the Atlantic ridge off to the northeast and Tropical Storm Gamma moving into the Yucatan Peninsula. Rain chances will continue to taper back as more dry air filters in behind the departing trough. A low level trough will move northwest of our area through the overnight period.
-Mottice Upper ridge over the Pacific Northwest gets shoved a bit into Montana Sunday while at the surface, a trough over Alberta begins it's drop to the southeast. This will allow warmer air to begin moving into the CWA Sunday as surface winds increase from the south then southwest.
651 PM CDT Sat Oct 3 2020 Extensive cloud cover remains in place this afternoon as a trough swings through.
733 PM EDT Sat Oct 3 2020 Broad troughing aloft will flatten by mid-week, allowing temperatures to at least briefly warm to above normal. The trough and associated cooler temperatures may become re-established later in the week. Min temps will drop below normal overnight and while the higher elevations could observe frost during the early morning hours, expect temps elsewhere across the mountains to remain warm enough to keep any frost concerns at bay.
527 PM MDT Sat Oct 3 2020 Clear skies and dry weather remains on tap this afternoon, as the persistent ridge of high pressure spins over the western CONUS. The next Pacific NW trough begins to dig along the Canadian coast Sunday, flattening the ridge of high pressure overhead. Otherwise, dry air under the ridge returns clear skies and deep mixing brings breezy afternoon conditions.
844 PM CDT Sat Oct 3 2020 A cold front is currently on the doorstep of Northeast Arkansas. Low temperatures will be warmer tonight with readings in the upper 40s to mid 50s. A cold front will swing through the area later tonight into early tomorrow morning from the north.
1039 PM EDT Sat Oct 3 2020 High pressure builds in tonight before moving east late Sunday.
1026 PM EDT Sat Oct 3 2020 Broad troughing aloft will flatten by mid-week, allowing temperatures to at least briefly warm to above normal. The trough and associated cooler temperatures may become re-established later in the week. Min temps will drop below normal overnight and while the higher elevations could observe patchy frost during the early morning hours, expect temps elsewhere across the mountains to remain warm enough to keep any frost concerns at bay.
Tight pressure gradient over the area with inverted trough located offshore. Strong high pressure will be north of the region Today, as an inverted trough develops along the coast. Weak area of low pressure is expected to develop in this coastal trough overnight, then lift northeast of the region during the day on Sunday. The chance will extend across the region during the day Sunday, as a boundary associated with the low lifts across area. The tightened pressure gradient between the high and trough will result in gusty winds along the coast this afternoon and evening.
At the surface, weak low pressure was located over the SW MO Ozarks with a cold front stretching southwest roughly down the I-44 corridor. The latest CAM guidance suggests that the northern band will eventually intensify and produce showers and isolated thunderstorms near or just north of the I-40 corridor this evening, forced by increasing QG and low/mid level cold frontogenetic forcing on the cool side of the surface front. /Issued 135 PM CDT Sat Oct 3 2020/ A cold front is just starting to traverse the area from northwest to southeast with meager moisture and instability to work with at the moment. After a cool day in the wake of the cold front Sunday, a warming trend will ensue thanks to mid level heights slowly rising through the week.

640 PM EDT Sat Oct 3 2020 High pressure will build into the region from the west tonight and slowly move east of the area by Sunday night.
At 500 MB, a broad, deep trough is in place across the eastern half of the CONUS with ridging building across the western CONUS. By 00 UTC Monday, high pressure will be directly overhead at the surface and aloft with light winds. Temperatures will be slightly warmer with highs in the mid to upper 50s but still 10 to 15 degrees below normal for early October. Current forecast is on the high end of guidance. This translates to warmer temps with drier air. VFR conditions are expected at all TAF sites through the forecast period as high pressure moves into the region at the surface and aloft. North wind of 5 to 10 MPH today will become light and variable this evening with high pressure directly overhead.
333 AM EDT Sun Oct 4 2020 High pressure will be in control today.
1135 PM CDT Sat Oct 3 2020 Extensive cloud cover remains in place this afternoon as a trough swings through. Winds will continue to strengthen through at least early afternoon Monday ahead of an approaching trough. The trough axis will begin pushing in late in the day which will allow winds to begin to subside.
Trough will rotate south and east through the Midwest and Ohio Valley. Associated cold frontal system will push across the Ohio Valley by late in the day on Sunday. A series of ridges of high pressure will keep the weather across eastern Kentucky dry through the end of the week. Cooler than normal temperatures are expected to start things off, with daily highs in the 60s on Monday.
