A weak cold front is currently located from near Musselshell to Forsyth to near Alzada this evening, and will work westward through the area tonight into tomorrow morning turning winds to the east and bringing cooler temperatures to the area on Wednesday. Chambers Warm and breezy this afternoon with upper level ridge west of Montana supporting northwesterly flow aloft. Backing flow aloft will allow a weak backdoor cold front to slip into the area from the northeast overnight.
741 PM CDT Tue Oct 6 2020 High pressure and dry weather will continue to dominate central and southeast Illinois through much of the week.
GOES satellite imagery shows clouds mid- and upper-level clouds, associated with a trough passage, encroaching on the Pittsburgh metro. Weak cold advection behind the front will not take hold until very late in the day, so with plenty of insolation and warmer air in place, temperature on Wednesday will rise about 5 degrees above the calculated-normal.
612 PM CDT Tue Oct 6 2020 It looks quiet with a warming trend as an upper level ridge shifts east into the central CONUS.
current dewpoints are running several degrees warmer compared to 24-hrs ago. This additional moisture will aid in overnight temps being slightly warmer than this mornings lows.
Data does indicate the potential for some patchy IFR or blo stratus around dawn Wednesday in the lower Arkansas River valley, near the KFSM terminal. A warming trend will continue into tomorrow as an upper ridges shifts eastward from the Southwestern US.
Skies will remain partly cloudy across the area this evening, with lows in the low to mid 70s along the interior, and mid to upper 70s along the coast.
/issued 303 PM EDT Tue Oct 6 2020/ The low level easterly flow will continue into Wednesday as high pressure moves off the Mid-Atlantic coast and out into the Atlantic Ocean. Temperatures will climb back into the upper 80s to lower 90s and this combined with the high humidity will push heat indices back above 100 degrees Wednesday afternoon.
1029 PM EDT Tue Oct 6 2020 Currently - The Keys are in a tight pressure gradient between a ridge straddling the southeast Atlantic Coast and Hurricane Delta racing towards the northern Yucatan peninsula. Forecast soundings indicate the lower level weak inhibition will weaken late in the overnight period. A tight pressure gradient between Hurricane Delta and a ridge straddling the southeastern Atlantic Coast will maintain fresh to strong east to southeast breezes across Florida Keys waters through the overnight period.
Patterson (Issued 225 PM CDT Tue Oct 6 2020) Tonight through Wednesday night: Another warm and breezy day across southern WI with highs climbing into the lower 70s. Otherwise there will be a brief westerly wind shift behind the front with overnight temps falling into the low 50s. Despite the early morning boundary, still expecting another warm day for Wednesday as upper-level northwesterly flows setups across the region and high pressure begins to build down from the Canadian Plains into the Upper Midwest overnight Wednesday.
A longwave trough axis is pushing east through the northeastern states as well. It's trailing front should allow an area of high pressure to begin building into the Tennessee Valley overnight. High pressure starts to break down on Wednesday. Warming temperatures aloft will allow for highs to get up into the low 80s across northern Alabama and southern Middle Tennessee.
Dry conditions with warmer than normal temperatures will continue through the end of the work week. Warmer temperatures will persist through the weekend, but rain chances will return then as the remnants of a tropical system move to the south of the area. High pressure will remain firmly in control across the region through the night with clear skies.
726 PM EDT Tue Oct 6 2020 A modest warming trend will precede a gusty cold frontal passage on Wednesday. Light rain showers associated with the passing cold front are possible across the northern tier of central PA.
/issued 322 PM CDT Tue Oct 6 2020/ Warmer temperatures are on tap for the next couple of days. Expect above normal highs in the low to middle 80s with lows mostly in the 50s.
High pressure over the Tennessee Valley is leading to mostly sunny skies and mild weather, with temperatures this afternoon generally in the upper 70s to near 80 degrees. High pressure starts to break down on Wednesday. Warming temperatures aloft will allow for highs to get up into the low 80s across northern Alabama and southern Middle Tennessee.
A weakening area of high pressure over the Great Basin continues to slowly recede east.
536 PM EDT Tue Oct 6 2020 A modest warming trend will precede a gusty cold frontal passage on Wednesday. Light rain showers associated with the passing cold front are possible across the northern tier of central PA.
Tonight: Our region will remain in the weakness between a mid-level ridge over the Rockies & over the western Atlantic & southeast CONUS. At the surface, high pressure ridge axis will be centered over the Tennessee Valley & Mid-South & down into our area. However, we still should be able to radiate down into the low 50s in the Delta to near to above normals in the east-southeast into the upper 50s-low 60s.
944 PM CDT Tue Oct 6 2020 (Issued 945 PM CDT Tue Oct 6 2020) Showers to the north associated with the cold front continue to drift southeast are expected to push into drier air and slowly dissipate from the west. Kuroski (Issued 225 PM CDT Tue Oct 6 2020) Tonight through Wednesday night: Another warm and breezy day across southern WI with highs climbing into the lower 70s. Otherwise there will be a brief westerly wind shift behind the front with overnight temps falling into the low 50s. Despite the early morning boundary, still expecting another warm day for Wednesday as upper-level northwesterly flows setups across the region and high pressure begins to build down from the Canadian Plains into the Upper Midwest overnight Wednesday.
907 PM CDT Tue Oct 6 2020 High pressure remains located over Northern Alabama this evening. /issued 322 PM CDT Tue Oct 6 2020/ Warmer temperatures are on tap for the next couple of days. Expect above normal highs in the low to middle 80s with lows mostly in the 50s.
605 PM CDT Tue Oct 6 2020 High pressure and dry weather will continue to dominate central and southeast Illinois through much of the week.
Towards the surface, this is driving a cold front that quickly overrunning the area with increased northwesterly winds throughout the column. Clouds have effectively limited the amount of heating across the area (except in southeast ND where sunshine is allowing for temps nearing 80) with temperatures still stuck in the lower 60s within the Devils Lake basin with other areas slow to rise into the 70s. Given the increased wind field and low freezing level, wouldn't be surprised to hear of convectively induced, non-severe gusty winds and/or small hail. Overall looking for cooler temps tomorrow with highs remaining in the 60s and dry conditions to continue. Wednesday night's low temps dip into the 30s, coolest near northwest MN at around the freezing mark.
High pressure remains the dominate feature across the Central High Plains bringing dry conditions and mostly clear skies. Mostly clear skies and dry conditions continue through the week into the weekend as high pressure remains the dominate feature across the Central Plains.
Some showers and storms will be possible mainly just south of the JAX Metro terminals this afternoon but chances remain on the low side at this time so only VCSH is in place.
This will set up a cooler day today, although one still above average by climatological standards. Additionally, with temperatures a couple/few degrees warmer than today's values, will see afternoon RH values drop back into mid 20s to mid 30s in many areas.
Upper level ridging over the southeast states will gradually breakdown through the near term as Delta tracks northwest from the tip of the Yucatan Peninsula to the western Gulf of Mexico as a major hurricane.
Higher gusts cannot be ruled out as forecast soundings are indicating some instability right above the mixing layer, with the mid-level cold air advection, which may be enough to eventually raise the layer, which would put the higher winds above this level in play. Weak low-level cold advection behind the front will not take hold until very late in the day, so with plenty of insolation, and warmer air in place, temperature today will rise about 5 degrees above the calculated-normal.

Expect quiet conditions again tonight, with lows slightly warmer than last night, ranging from the middle/upper 50s north to middle 60s acrs the Acadiana region.
A cold front associated with this low, was slowly moving south into the area. This cold front is expect to sag across the area today. High pressure behind this front is expected to build into the area through the short term. Discussion: The cold front is expected to move into the area through most of the day. H85 cold front stalls out across the CWA.
243 AM EDT Wed Oct 7 2020 Warm temperatures are expected today, before a cold front moves into the area this evening.
It could be breezy again across north central North Dakota Wednesday afternoon, which lies farther away from the ridge axis. A back door low level cold front moving down from Canada earlier on Wednesday will limit highs to the 60s. An upper level ridge is forecast to build over the Northern Plains on Thursday.
343 AM CDT Wed Oct 7 2020 A seasonably mild night is underway across the TN Valley, with mostly clear skies and temperatures in the lower to mid 50s. At the surface, high pressure centered over the area should keep winds light, with mostly sunny skies allowing temps to warm into lower 80s. Another mild night is expected tonight as high pressure remains over the area. Dry conditions will persist into Thursday, as weak ridging builds aloft. Temperatures will be a couple of degrees higher on Thursday, as highs warm into the lower to mid 80s.
Nonetheless, the low rain chances are still in the forecast over the weekend for the southern and eastern portions of central Indiana as the tropical remnants of Delta try to enter the forecast area.
Otherwise, temps will be a bit cooler across the area compared to yesterday.
126 AM EDT Wed Oct 7 2020 A cold front will arrive on Wednesday bringing slightly cooler air for Wednesday night and Thursday before much warmer temperatures arrive into the weekend. Cold front will drop across the area during the day Wednesday with only noticeable impact being the wind shift to the NW and some breezy conditions behind the front. 850 temps will drop into the single digits briefly Weds night into Thursday to bring slightly cooler conditions.
A slight break in the temps back into the U80s and L90s will be forecast for Thursday as heights fall briefly with the weak trough axis over the state.
350 AM EDT Wed Oct 7 2020 High pressure builds over the area with warming temperatures through Thursday.
06z surface map indicated a weak cold front laid out to our north early this morning from WI into northern IA. Tonight, high pressure begins to filter in from the upper Midwest, continuing our tranquil weather pattern. The ridge will shift across the lower Great Lakes on Thursday, with the light east flow knocking a few degrees off highs, mainly mid 70s to low 80s far southeast IL.
206 AM CDT Wed Oct 7 2020 Currently have a band of scattered showers draped along a cold front extending from near Green Bay WI to near Minneapolis MN. Otherwise, temperatures as of 2 am were pretty mild for early October with reading ranging from the mid 50s to the lower 60s. High pressure builds in behind the departing front with a fairly decent pressure gradient in place.
A weak cold front will enter the area late Wednesday, and will in effect wash out by Thursday morning, as pressures lower on the Gulf Coast ahead of Hurricane Delta. Although winds will become northeast or east throughout the area by Thursday morning, there will be little push of drier or cooler air into the forecast area. Temperatures will be substantially warmer for both lows and highs through the period. With the impact of the cold front trending downward, highs on Thursday will likely still reach the lower 80s everywhere.
/issued 907 PM CDT Tue Oct 6 2020/ High pressure remains located over Northern Alabama this evening. /issued 322 PM CDT Tue Oct 6 2020/ Warmer temperatures are on tap for the next couple of days. Expect above normal highs in the low to middle 80s with lows mostly in the 50s. A weak cold front will move across the Midsouth late Thursday ahead of what is left of Hurricane Delta. Clouds rain associated with Delta, as well as a drier air mass behind the cold front will result in cooler, near normal temperatures.
An upper ridge slides over the Dakotas from tonight into tomorrow, which will bring plentiful sunshine today and clear skies tonight. Winds decrease tonight and temperatures will fall into the 30s and 40s, with areas in the northeast near the freezing mark. Thursday highs will be similar to today, perhaps a deg or two warmer across the south.
Expect a brief respite in the smoke across portions of the area today, as winds temporarily shift into the east behind a weak backdoor cold front by this afternoon. However, expect this trend to be short-lived as winds shift back into the west and increase for Thursday as the front lifts northeast as a warm front. With the arrival of the front, it should be a few degrees cooler today with highs in the mid 70s (west and north) to mid 80s (south and east).
We will fall a bit short of record highs (which are in the lower 90s). Warm and dry conditions will then continue into Thursday with highs once again getting into the lower to middle 80s.
The upper ridge remains stretched from the Pacific NW all the way sewd into FL, and a weak piece of energy is pinched off under the ridge over N TX. High pressure remains in place at the sfc across our area. Upper low over N TX to open up over the next 24 hours or so, as the upper ridge dampens and the main jet to our n becomes more zonal in nature.
To begin, a large scale ridge remains parked over the Desert Southwest with a broad trough near the Great Lakes region. Over the next couple days, the low is expected to deepen within weak southwesterly flow. This upper low is expected to deflect the hurricane towards the northeast. Temperatures through the period will slowly moderate and winds will be variable with areas of high pressure displaced east of the region.
Today, upper level ridging will build into the region. Weak upper ridging will remain in control Thursday with light easterly to southeasterly flow at the surface as the front remains stationary across the CWA.
This is in line with the latest NBM output which shows fairly low spread in the high temperature forecast for today.
207 AM MDT Wed Oct 7 2020 Water vapor shows upper ridge over the Pac NW building into the Northern Rockies. Short wave embedded in the northwest flow is moving through the Upper Midwest, and driving a backdoor cold front southwest through western SD early this morning. Backdoor front will continue southwest through northeast WY this morning, with easterly boundary layer flow resulting in highs about 10F cooler than yesterday. Front then lifts back northeast through the area as a warm front on Thursday as upper ridge builds in.
Deep-layer ridging remains situated across the Western CONUS with a departing trough now moving off the Northeast Coast. After morning low-level clouds mix out in some areas, I suspect we'll see high temperatures in the low to upper 80s as abundant insolation leads to forecast above average temperatures.
247 AM CDT Wed Oct 7 2020 Warmer this morning versus yesterday with current temps in the mid 40s to mid 50s. Otherwise, a big warming trend will begin today as an upper ridge of high pressure builds across the southeast states. Highs will reach the 80s for most everyone west of the Plateau, and mid 80s are possible in the typically warmer urban areas like Nashville. Tomorrow looks very similar to today and maybe a touch warmer with highs well into the upper 70s and 80s.
1128 PM MDT Tue Oct 6 2020 An upper level ridge will be centered over the area tonight and Wed, keeping the weather dry. Temps on Wed will be above average, with highs in the 80s to lower 90s over the plains and mostly in the 70s in the high valleys, and in the upper 60s and lower 70s in Teller County.
353 AM CDT Wed Oct 7 2020 Southwest flow around high pressure centered over the lower TN Valley will bring a return of late summer warmth. A weak, moisture-starved cold front will pass through the region late tonight. High temperatures Thursday will be slightly cooler, in the lower to middle 80s.
Today through Thursday: Increasing high pressure will promote clear skies during the day today. Despite the lower winds and clear skies, large scale ridging will prevent our night lows from dipping down to freezing overnight Wednesday into Thursday High pressure and clear skies will linger through Thursday.
358 AM EDT Wed Oct 7 2020 A cold front will move across the area today and bring gusty winds, although temperatures will still be mild for this this of year with highs in the 70s.
1114 PM CDT Tue Oct 6 2020 High pressure and dry weather will continue to dominate central and southeast Illinois through much of the week. A weak cold front will push through the area Wednesday bringing slightly cooler temperatures for Thursday. Weak cold front currently is analyzed across southern Minnesota into northern Nebraska, and is on track to move into the forecast area after sunrise. Weak cold front is now near the Illinois River, but little in way of sensible weather impacts other than a wind shift and a bit of gustiness. 12z ECMWF is matching up better with the GFS in keeping the bulk of the energy in the main trough and cutting it off from the northern jet.
Otherwise high pressure ridge will continue building overhead as the afternoon heats up to unseasonably warmer temperatures. Western Oklahoma and western north Texas will be the hottest with high temperatures in the lower 90s, to mid to upper 80s across the central one third of Oklahoma, but will be far from breaking any kind of records.
1151 PM CDT Tue Oct 6 2020 It looks quiet with a warming trend as an upper level ridge shifts east into the central CONUS.
Slightly cooler air will move into the region on Wednesday, however, warm and windy conditions will return by Thursday.
Tonight, light southeast winds will develop as mixing ceases and generally mild overnight lows in the 50s will be found in south central Kansas and possible cooler 40s in the western counties.
The ridge of high pressure will persist over the West today, though its axis will be sliding eastward in response to a mid- level trough approaching the West Coast. Little to no moisture was indicated in the atmospheric column over the region today so expect sunny skies and highs around 10 degrees warmer than normal. Cooler, unsettled weather arrives later this weekend, but until then look for dry and unseasonably warm conditions to continue.
High pressure will loosen its grip on the Great Basin this week.
654 AM CDT Wed Oct 7 2020 Overall upper level ridging continues to give us warmer than normal temperatures as the jet streak to the north will ensure dry weather for the rest of the week. The smoke did keep me from going much higher than the mid 80s for tri-cities today, and if smoke gets to thick aloft, we may not reach the lower 90s in our south, but I think the dryness of the air will compensate in this case. A dry cold front will shift wind to the north/northeast, but should remain light as the surface gradient will not be too compressed.
1059 AM EDT Wed Oct 7 2020 Currently - A band of showers continues to stream across mainly the Lower and Middle Keys this morning. These showers are moving rather quickly through the southeast flow thanks to a tightened pressure gradient between a western Atlantic high pressure and Hurricane Delta currently moving across the Yucatan Peninsula. Observations there reveal 20 to 25 knots with the highest at Sand Key Light.
As high pressure moves over the southeast temperatures will rise with afternoon highs in the middle 70s to lower 80s. with the usual few warmer spots reaching the middle 80s.
Warmer this morning versus yesterday with current temps in the mid 40s to mid 50s. Otherwise, a big warming trend will begin today as an upper ridge of high pressure builds across the southeast states. Highs will reach the 80s for most everyone west of the Plateau, and mid 80s are possible in the typically warmer urban areas like Nashville. Tomorrow looks very similar to today and maybe a touch warmer with highs well into the upper 70s and 80s.
517 AM MDT Wed Oct 7 2020 Water vapor shows upper ridge over the Pac NW building into the Northern Rockies. Short wave embedded in the northwest flow is moving through the Upper Midwest, and driving a backdoor cold front southwest through western SD early this morning. Backdoor front will continue southwest through northeast WY this morning, with easterly boundary layer flow resulting in highs about 10F cooler than yesterday. Front then lifts back northeast through the area as a warm front on Thursday as upper ridge builds in.
Southwest flow around high pressure centered over the lower TN Valley will bring a return of late summer warmth. A weak, moisture-starved cold front will pass through the region late tonight. High temperatures Thursday will be slightly cooler, in the lower to middle 80s.
High pressure overhead has produced clear skies and light winds which will allow for temperatures to quickly warm up into the lower 80s by this afternoon. Another mild night is expected tonight as high pressure remains over the area. Dry conditions will persist into Thursday, as weak ridging builds aloft. Temperatures will be a couple of degrees higher on Thursday, as highs warm into the lower to mid 80s.
This will turn winds to the east today and provide cooler and less dry air.
/issued 424 AM CDT Wed Oct 7 2020/ Broad high pressure centered over northern Louisiana into southern Arkansas this morning is yielding very light to calm winds across the area.
633 AM CDT Wed Oct 7 2020 Temperatures on track and still expecting temps in upper 60s across the south, where NBM was a few deg cooler than HRRR guidance, preferred the latter based on recent performance. An upper ridge slides over the Dakotas from tonight into tomorrow, which will bring plentiful sunshine today and clear skies tonight. Winds decrease tonight and temperatures will fall into the 30s and 40s, with areas in the northeast near the freezing mark. Thursday highs will be similar to today, perhaps a deg or two warmer across the south.
This high will try to remain dominant across our CWA through tonight as moisture begins to slowly increase from the south. Temperatures today will again top out warmer than normal in the mid 80s at most sites. Lift will be provided by the way of a warm front lifting through the lower MS River Valley out ahead of the approaching Delta.
424 AM CDT Wed Oct 7 2020 Broad high pressure centered over northern Louisiana into southern Arkansas this morning is yielding very light to calm winds across the area.
High pressure will remain in control, for the short term. This will help maintain temperatures warmer than seasonal normals, with afternoon highs today mainly around 90.
Upper level high pressure over southern Colorado more typical of mid summer will remain, while a very weak upper trough along the Red River will edge northwest into the Rolling Plains this afternoon but will not have any moisture or lift.
738 AM EDT Wed Oct 7 2020 WV imagery and RAP analysis indicated a mid/upper level low over northern Hudson Bay with a broad trough extending into the northern Great Lakes. At the surface, northwest winds were increasing between a deepening low exiting from northern Ontario into Quebec and a ridge building into the Plains.
