352 AM CDT Tue Oct 10 2023 Key Messages: 1) Gradual warming trend beginning today, with above normal highs by Wednesday as a warm front lifts northward through the region. 2) That same warm front will interact with sufficient moisture and forcing to cause showers and thunderstorms late tonight into Wednesday morning mainly north and west of the St. 3) Warm temperatures persist into the latter part of the work week behind the warm front.
Seasonable temperatures will see highs in the upper 70s today, however conditions will be cooler over the coming days due to thick upper level cloud cover.
Broad cyclonic flow extending from an occluded low pressure system meandering over southern Ontario/Quebec through the period will continue to influence the weather across central NC through this evening. A southern stream s/w trough over the western GOM will eject NE through the mid South and Southeast US during the day on Wednesday and then into the Carolinas Wednesday evening/night.
340 AM EDT Tue Oct 10 2023 High pressure will lead to mainly dry conditions and slightly below normal temperatures today and Wednesday. A chance of showers will develop later Wednesday into Wednesday night as a warm front lifts north across the region. The warm front will also result in a warming trend through the end of the work week. Highs today will be in the low to mid 60s. High pressure will remain centered off to our southeast tonight. A warm front will lift northeast toward the Ohio Valley through the day on Wednesday. Warm frontal boundary attached to a strengthening surface on the lee side of the Rockies will be stretched across the central/eastern CONUS.
339 AM EDT Tue Oct 10 2023 With a large upper level low spinning over southeast Canada over the next few days, cool and cloudy conditions continue through mid week. A stalled upper level low spins north of the Great Lakes resulting in a more southwesterly flow pattern today. The moisture associated with the upper level low is far enough northwest to keep conditions dry for our area. This pattern is expected to continue overnight with lows falling into the low to mid 40s. As the upper level low begins to shift eastward on Wednesday the potential to see a chance of showers increases slightly. Temperatures are expected to be a couple degrees warmer with highs ranging in the upper 50s to low 60s.
A cold front now along interstate 44 will move into northern Arkansas late tonight.
Not a lot of forcing along the front as there's no strong push of high pressure behind it and the upper flow is largely parallel to it.
Currently thinking that the majority of the area will be dry slotted with the exception of NW and northern counties; but will all be dependent on the low position.
Increased moisture and an active pattern will provide chances for rain through the end of the week before a cold front ushers in drier air for the weekend. One more full day and night of dry conditions should occur as high pressure across the region begins to move out of the area. More widespread thicker cirrus clouds should not arrive until after peak heating this afternoon, so with some low-level warm advection across the region, temperatures will be able to rise into the lower 80s. Lows also warmer, around 60.
As the subtropical jet buckles and takes on a more anticyclonic curvature, expect ascent in the entrance region to increase as we go into Wednesday morning with rain chances picking up quickly by that time along/south of the Highway 84 corridor.
739 AM EDT Tue Oct 10 2023 A large and nearly stationary upper low will be located between James Bay and Georgian Bay today and Wednesday before drifting gradually east to Nova Scotia late this week.
Cooler seasonable temperatures are expected through the rest of the week.
650 AM CDT Tue Oct 10 2023 Temps are 30 degrees or below in 95 percent of the forecast, with exceptions those sites near bodies of water which are warmer. Sunny, except far northeast fcst area where clouds will move in from the east-northeast as moisture wraps back around the upper low in western Quebec. Clearer sky in the west/southwest fcst from Devils Lake to Forman will allow lows to drop below freezing by late tonight.
956 AM EDT Tue Oct 10 2023 A rotating upper level low remains north of the Great Lakes over the next few days. A stalled upper level low spins north of the Great Lakes resulting in a more southwesterly flow pattern today. The moisture associated with the upper level low is far enough northwest to keep conditions dry for our area. This pattern is expected to continue overnight with lows falling into the low to mid 40s. As the upper level low begins to shift eastward on Wednesday the potential to see a chance of showers increases slightly. Temperatures are expected to be a couple degrees warmer with highs ranging in the upper 50s to low 60s.
730 AM EDT Tue Oct 10 2023 Current water vapor imagery continues to show a persistent low pressure system centered over the Ontario/Quebec province line early this morning. There also won't be much change in temperatures for today and tonight with highs topping off in the low to upper 40s and lows generally in the mid to upper 30s. The exceptions will be along the lakeshores and interior west where it will be warmer and cooler, respectively.
647 AM EDT Tue Oct 10 2023 Rotating upper level low remains north of the Great Lakes over the next few days. A stalled upper level low spins north of the Great Lakes resulting in a more southwesterly flow pattern today. The moisture associated with the upper level low is far enough northwest to keep conditions dry for our area. This pattern is expected to continue overnight with lows falling into the low to mid 40s. As the upper level low begins to shift eastward on Wednesday the potential to see a chance of showers increases slightly. Temperatures are expected to be a couple degrees warmer with highs ranging in the upper 50s to low 60s.
558 AM EDT Tue Oct 10 2023 With a large upper level low spinning over southeast Canada over the next few days, cool and cloudy conditions continue through mid week.

709 AM EDT Tue Oct 10 2023 A large and nearly stationary upper low will be located between James Bay and Georgian Bay today and Wednesday before drifting gradually east to Nova Scotia late this week.
908 AM EDT Tue Oct 10 2023 High pressure will lead to mainly dry conditions and slightly below normal temperatures today and Wednesday. A chance of showers will develop later Wednesday into Wednesday night as a warm front lifts north across the region. The warm front will also result in a warming trend through the end of the work week. High pressure will remain centered off to our southeast tonight. A warm front will lift northeast toward the Ohio Valley through the day on Wednesday.

504 AM EDT Tue Oct 10 2023 A large and nearly stationary upper low will be located between James Bay and Georgian Bay today and Wednesday before drifting gradually east to Nova Scotia late this week.
620 AM CDT Tue Oct 10 2023 A weak cold front has pushed through the Mid-South allowing our high temperatures today to be a few degrees cooler than yesterday.
619 AM CDT Tue Oct 10 2023 Key Messages: - Frost or freeze potential will be higher Wednesday morning (Frost chance 30-60%), with the highest probabilities from southeast MN into southwest WI.
1028 AM EDT Tue Oct 10 2023 Drier air at the lower levels continues with the subtropical jet bringing mid and upper level moisture and cloudiness across the area. Stalled frontal boundary is in place across the southern tip of Florida, and this feature will begin to lift back to the north as a warm front tonight and Wednesday, turning winds to the east, allowing moisture to return, and moderating temperatures for the rest of the week. Despite the cloudy conditions in place, no rain is expected today as the dry slot in the lower 12,000ft would evaporate any precipitation. NE flow will continue today, then become more easterly tomorrow as a warm front lifts over the area.
The Keys remain on the northwestern periphery of an expansive mean layer ridge centered over Hispaniola and Puerto Rico, which is causing our southwesterly steering flow. From synopsis, weak high pressure sliding across northern Florida interacting with the stationary front draped across the Straits will result in gentle northeast to east breezes through this evening. The front will lift northward as a warm front late tonight and Wednesday, resulting in freshened southerly breezes.
Cooler temperatures and dry conditions will continue through the rest of the week.
626 AM CDT Tue Oct 10 2023 Key Messages: 1) Gradual warming trend beginning today, with above normal highs by Wednesday as a warm front lifts northward through the region. 2) That same warm front will interact with sufficient moisture and forcing to cause showers and thunderstorms late tonight into Wednesday morning mainly north and west of the St. 3) Warm temperatures persist into the latter part of the work week behind the warm front.
618 AM CDT Tue Oct 10 2023 (Today) Warm front lifts northward through the forecast area today with breezy and warm conditions by afternoon.
1005 AM EDT Tue Oct 10 2023 High pressure will remain in control through the rest of the week. Low pressure advancing northeast from the Gulf of Mexico combined with a cold front from the west will bring a chance of rain to the area late Fri into Sat. The surface front should be off the New Jersey coast with its cold front nearly entering the FA at the end of the period. A weak/dry cold front will sweep across the Carolinas Wed. A windshift to the northwest and slightly cooler high temps in the mid 70s will be the only sensible weather associated with the front.
625 AM EDT Tue Oct 10 2023 A weak cold front will drop south and stall over North Carolina today into tonight.
Low pressure south of James Bay will continue to weaken throughout the day today. As the area of low pressure weakens, the influence it has over the state of Wisconsin will also deteriorate. Due to the clearing skies tonight, light winds and temps in the low 30s frost will again be possible tonight.
A weak cold front has pushed through the Mid-South allowing our high temperatures today to be a few degrees cooler than yesterday.
634 AM EDT Tue Oct 10 2023 High pressure will lead to mainly dry conditions and slightly below normal temperatures today and Wednesday. A chance of showers will develop later Wednesday into Wednesday night as a warm front lifts north across the region. The warm front will also result in a warming trend through the end of the work week. Highs today will be in the low to mid 60s. High pressure will remain centered off to our southeast tonight. A warm front will lift northeast toward the Ohio Valley through the day on Wednesday. Warm frontal boundary attached to a strengthening surface on the lee side of the Rockies will be stretched across the central/eastern CONUS.
Lows should range from the mid to upper 60s tonight and in the low to mid 60s on Wednesday night.
Storm system will bring the highest chances/greatest qpf to southern MT during the middle of this week.
Cooler temperatures and dry conditions will continue through the rest of the week. Mid to upper-level winds will continue to increase through tonight in response to a low pressure system anticipated to push through the Intermountain West on Wednesday.
An H5 upper low continues to move slowly westward, bringing low to mid level cloud cover into the region from northeast to southwest. Temperatures are expected to remain above freezing where clouds prevail, with mid 20s to low 30s where skies remain clear. Winds will gradually increase out of the east as an upper low approaches the area from the southwest. Highs are expected to reach the lower to middle 50s.
319 PM EDT Tue Oct 10 2023 A frontal boundary stalled across the southern tip of Florida will start to lift back to the north as a warm front overnight and Wednesday, lifting north of the area and turning winds to the E/SE. At the same time, an area of low pressure over the Bay of Campeche will lift north and northeast over the Gulf of Mexico and merge with this boundary.
Early Season Snow Expected Thur-Fri in the Black Hills Potent NE Pac upper trough digging into the Pac NW as the stubborn Hudson Bay low retrogrades slowly west. This will eventually support a vigorous wrapped up sfc cyclone by Thur in the central Plains, with locally widespread moderate to heavy rains and snow in the higher elevations of the region. Staunch Pac NW trough will push into the central Rockies Wed, supporting pos theta-e adv over the FA.
337 PM EDT Tue Oct 10 2023 High pressure will prevail through Wednesday morning.
Overnight lows will be in the lower to middle 40s while afternoon highs tomorrow reach back into the 60s and 70s. Cool and dry weather will be around one more night as high pressure slowly shifts east-southeast. This first wave of precip will be associated with a warm front forming to the west and then lifting north through the area on Wed & Wed night. Auten With the warm front across northern IL, warmer air will sit over the CWA for Thur into Thur night. However, this will be short lived as the cold front associated with the strong system moves into the area for the last part of the weekend. Unfortunately the low pressure area with this system will slowly move east.
The large upper level low situated over SE Ontario will continue to dominate the weather pattern through the near to mid term period. Temperatures will continue to be below normal today and tomorrow with the northwesterly flow bringing cooler air.
Another round of river valley fog will once again be possible overnight with areas around northeast TN and southwest VA having the highest chances to see fog. Warm weather last couple work days will slide cooler into cool weather through the weekend and beyond.
High pressure overhead shifts to the northeast tonight as an area of low pressure develops over the western Gulf.
1220 PM CDT Tue Oct 10 2023 (Today through Wednesday Night ) An upper level ridge is over the Rockies this morning with a large upper low over the Great Lakes region. The upper low will spin over the Great Lakes through Wednesday as the ridge moves east and another upper low enters the Pacific Northwest. Expect some mid and high level clouds today central and south, south of a weak cold front. This front will lift north tonight as a warm front. High pressure will again be over the area Wednesday.
345 PM EDT Tue Oct 10 2023 Short Term/Marine Big upper low that has been retrograding across SE Canada will be reaching its furthest west longitude tonight then gets kicked out by another upper low currently moving into the Pacific Northwest. One thing to watch for will be the potential for frost and freezing temperatures across the northern forecast area Wednesday night should skies remain mostly clear.
134 PM CDT Tue Oct 10 2023 A warm front is poised to surge northward into the area later tonight-tmrw. While the better focus for showers/storms will be outside our region, closer to the genesis of its low pressure field developing in the Central Plains, we do see both K and Showalter Indices still supportive for elevated thunder translate w/the boundary along our nw corridor in the 06z-15z time frame tonight and early tmrw. We effectively warm sector, dry, and cap after late morning, and high temps respond accordingly, pushing the lower 80s in our south and likely reaching at least the upper half 70s everywhere.
(This evening through Wednesday Night) Conditions to gradually destabilize across the region through tonight into Wednesday as an upper-level trough approaches the ArkLaTex from the west. Cool temperatures to persist with overnight lows in the lower 60s tonight and highs on Wednesday in the mid to upper 70s.
(Through tonight ) A weak warm-frontal boundary draped across northeastern OK and northwestern AR will continue to lift northward through the remainder of the afternoon and tonight as the low-level pressure gradient begins to tighten and southerly winds increase. Lows tonight will be much warmer -- about 10 degrees -- than last night, mainly ranging from the mid- upper 50s across far northeast OK and far northwest AR to low-mid 60s elsewhere.
1244 PM CDT Tue Oct 10 2023 Key Messages: 1) Gradual warming trend beginning today, with above normal highs by Wednesday as a warm front lifts northward through the region. 2) That same warm front will interact with sufficient moisture and forcing to cause showers and thunderstorms late tonight into Wednesday morning mainly north and west of the St. 3) Warm temperatures persist into the latter part of the work week behind the warm front.
Near the surface, a lee side trough of low pressure is slowly strengthening in eastern Colorado. Temperatures will not be quite as cool tonight as prevailing southerlies continue to draw slightly warmer air into the high plains. Aforementioned prevailing southerlies will reinforce the warmer air mass across the high plains Wednesday, resulting in afternoon highs in the mid/upper 80s(F) to possibly the lower 90s(F).
(This evening through Wednesday) Warm, above-average temperatures will continue tomorrow with the Southern Plains on the eastern periphery of a low-level thermal ridge.
Temps are 30 degrees or below in 95 percent of the forecast, with exceptions those sites near bodies of water which are warmer. Sunny, except far northeast fcst area where clouds will move in from the east-northeast as moisture wraps back around the upper low in western Quebec. Clearer sky in the west/southwest fcst from Devils Lake to Forman will allow lows to drop below freezing by late tonight.
A warm front will move over the Gulf Coast and bring in rain showers tomorrow afternoon.
This will keep the high temperatures near seasonal average for most of us (upper 70s to low 80s) except the far west counties where clouds are forecast to dissipate during the afternoon hours.
The upper level low that has been aiding in the unsettled pattern the past few days will finally lift further north. Winds will begin to calm a bit beginning today into tomorrow, especially for our southern areas as the ridge axis situates over the southern peninsula. The ridge axis will be pushed south once again early in the week allowing for the return of the increased westerly flow.
Ridging will build into the region as clearing occurs during the morning. Additionally, Tds will remain rather high which will drive the heat indices up into the low 100s across parts of Southeast Kansas and possibly into South Central Kansas during the afternoon. Saturday night, a cold front will begin to encroach on the region.
Short wave ridge will build in for Saturday and that will keep the forecast dry. It will be quite a bit warmer though with highs in the upper 80s to lower 90s.
This will permit the weak cold front to push farther into the area by early morning followed by a reinforcing shot of cooler air that moves the front south/east of the area during the evening. However, by mid evening that will be replaced with cooler air behind north to northeast winds as temps drop into the upper 50s to lower 60s for overnight lows.
Quiet weather will continue into tonight across the region as the cut-off low pressure that has plagued us all week continues to depart to our east. Ridging will continue to increase in its wake, ensuring dry conditions continue overnight. Heat and humidity will become much more noticeable Saturday as a 586-590 dm H5 ridge begins to shift our direction from the southern Plains. This will allow high temperatures Saturday to reach the lower to middle 90s. Dew point temperatures will be fairly manageable, in the lower to middle 60s.
The rain could be especially heavy over eastern portions of Southwest and Central Montana, which could lead to instances of Flash Flooding, especially near the higher terrain.
Scattered convection associated with cut off upper low over Lk Erie should diminish in coverage/intensity overnight as boundary layer cools. By late tonight, convection-allowing models indicate the focus of lingering showers will be over the western counties, closest to the upper low. Model soundings supports a low overcast across the region tonight, with ridgetops shrouded in fog. After a relative lull in precip/convection during the morning hours, expect diurnal convection to fire by afternoon under the remnants of the upper low. With the upper low overhead, some hail is also possible from the taller towers.
A trough of low pressure will lead to isolated to scattered showers and thunderstorms this afternoon and evening across northeastern Nevada. Fair and mild weather expected across the rest of the region as weak high pressure builds overhead. Isolated to scattered showers and thunderstorms is underway this afternoon as an upper level trough transits across the NV/UT border. The showers and storms will come to end tonight as the aforementioned trough exits the region. By Saturday, another round of scattered showers (20-35%) and thunderstorms (20-25%) is expected across northern NV during the afternoon/evening as a west coast trough pushes north and east. Meanwhile, a transient ridge of high pressure builds over central NV this weekend.
Lows tonight will range from the mid 60s in the east to the low 70s in the west. Dewpoints in the low to mid 70s will begin pushing into the area from the southwest by mid morning with heat indices rising to near 100 by noon. Current hi-res guidance show a short wave trough shifting east/northeast across the upper east coast. At the same ridging continues to build across the southeast US as the trough axis lifts further east towards the Carolinas. Because of this, drier air should continue to hover over much of central Mississippi which should help dewpoints peak in the low to mid 70s. These higher dewpoints should help afternoon temperatures peak in the low to mid 90s across the area for much of the weekend.
628 PM CDT Fri Jun 23 2023 (This evening through Saturday) An upper level ridge and general zonal flow aloft remains in place across West Central Texas, continuing the scorching hot and well above normal heat over the area through the weekend.
Additionally showers and thunderstorms have developed north of the warm front near the Brainerd Lakes region. This warm front is draped from western UP MI southwestward to western SD. An upper level low pressure over eastern WY/MT border will eject out over the plains tomorrow afternoon. As these move in tandem showers and thunderstorms are expected to develop north of the warm front.
1239 AM CDT Sat Jun 24 2023 (This evening through Sunday) Visible satellite imagery shows a limited Cu field across the state this afternoon thanks to sfc ridging in place over the area. H500 cyclone will move from the Northern Plains eastward toward the Great Lakes during this period.
424 AM EDT Sat Jun 24 2023 Weak high pressure is expected to build over the Southeast this weekend.
(Today through Sunday night) Models expect the 500mb center of high pressure to continue to build as it shifts northeast into Texas for the weekend. As it stands, latest guidance is projecting afternoon high temperatures for today to rise into the high 90s with triple digits becoming likely the further south you are located. As for Sunday, dry conditions should hold for day with the center of the high not expect to move too much. Temperatures will be slightly cooler, however, with afternoon highs projected to be in the high 80s and low 90s.
Thunderstorm chances increase over the east Saturday afternoon then more widespread storms ahead of a cold front Saturday night into early Sunday.
