1138 PM CDT Thu Oct 9 2025 -A cooler and drier airmass will be in place across Arkansas through the end of the workweek.
Outside of isolated rain and thunderstorm chances acrs Nrn AR this aftn, a persistence-style fcst is on deck for the Natural State thru the next 5-7 days as upper lvl ridging builds in over the Cntrl US. Have included higher PoP mentions, but QPF and covg of precip should remain on the low side.
Main focus for the short term is on a cold front passing through the area tonight. The cold front is poised to push through the area tonight into Saturday morning, though any forcing associated with the compact upper low accompanying it will be displaced to the north/northeast of the area.
High pressure over the St. The inbound system gradually dislodges the resident ridging with a tongue of higher theta-e that arrives later in the day. Conditions are expected to stay dry through the daytime for most of the area as the moisture transport remains elevated and dry air holds within the lowest 7000 ft or so. The exception will be the Saginaw Valley and Thumb where there will be a chance for some scattered showers along a warm frontal feature before sunset. Still, the cold front and plume of moisture along the system's southern flank will track southeast across the area bringing a chance for showers late this evening.
1247 AM CDT Fri Oct 10 2025 (Rest of tonight and Friday) The upper level pattern shows the Southeast under a trough with ridging out to our west. A vort max is dropping south and east along the base of the trough axis near the AL/GA state line. Northerly to northwesterly flow aloft continues to advect in a cooler and drier airmass. As a result, low temperatures tonight will dip down into the low to mid 50s.
- Rockslides and mudslides are possible along the highway corridors in the mountains. This moisture, which is embedded in southwesterly flow between high pressure over Texas and low pressure off the coast of the Pacific Northwest, comes from Tropical Storm Priscilla. Rockslides and mudslides are possible in the higher terrain.
Temperatures have warmed quickly into the low to mid 80s already, with highs expected to reach the mid to upper 80s in most areas by later this afternoon. Ware (Friday through Saturday night) Well above average temperatures will continue into the weekend as upper ridging builds over the area.
420 AM CDT Fri Oct 10 2025 - Cooler today, but overall above normal temperatures will persist into this weekend.
- Relatively cooler temperatures arrive next work week with small rain chances (20-30%). The upper level pattern still depicts a ridge influencing much of the southern and central CONUS, with a small low moving through Ontario and a larger low spinning off the Pacific coast. At the surface, an area of low pressure is noted in MN with an associated cold front draped across NE. Temperatures still look warm with highs in the 80s for most, with the upper ridge axis nearby. A subtle wave rounding the ridge looks to pass northwest of the area late tonight into Saturday morning, bringing mid to high clouds during that time but keeping us out of the path of any rain chances.
643 AM CDT Fri Oct 10 2025 (Today) A weak upper low was situated over the central AL/GA border. During the course of today, the above mentioned upper low should slowly move E-SE. This high should move offshore today, resulting in an easterly flow. Under partly cloudy skies, another seasonably warm day is expected, with high temperatures rising into the mid 70s (trending a bit warmer west, a bit cooler east).
1030 AM EDT Fri Oct 10 2025 Cooler, drier and breezy conditions expected into Friday with a Lake Wind Advisory in effect through the day. Temperatures today should be a bit cooler than yesterday with increased cloud cover and continued weak cool advection with highs in the upper 60s to lower 70s. Key message(s): - Cooler and breezy through the weekend with chances for showers in the east. Models are consistent in an upper low near the CSRA which will allow deeper moisture to penetrate inland. With the increased clouds and precip chances, along with northeasterly winds, cooler conditions will continue with highs in the mid 70s in the western area to around 70 in the east.
549 AM CDT Fri Oct 10 2025 - Dry and cooler conditions expected for Friday with highs in the mid to upper 70s and northeasterly winds at 10 to 15 mph.
624 AM CDT Fri Oct 10 2025 - Dry weather conditions with cooler mornings will prevail through this weekend. Expect afternoon highs to peak into the low 80s areawide. Global guidance continues to show upper ridging building to the west of our area looking into Saturday. The building upper ridge combined with drier air advecting across the southeast CONUS will allow for dry and quiet conditions to persist across our CWA through the weekend.
612 AM CDT Fri Oct 10 2025 - Cooler today, but overall above normal temperatures will persist into this weekend.
Outside of isolated rain and thunderstorm chances acrs Nrn AR this aftn, a persistence-style fcst is on deck for the Natural State thru the next 5-7 days as upper lvl ridging builds in over the Cntrl US. Have included higher PoP mentions, but QPF and covg of precip should remain on the low side. High pressure and overall upper level ridging continues to lead to fair weather conditions.
Many locations outside of urban areas fell into the low to mid 30s this morning, with the coldest locations in the Wabash River Valley and low lying areas. Main focus for the short term is on a cold front passing through the area tonight. The cold front is poised to push through the area tonight into Saturday morning, though any forcing associated with the compact upper low accompanying it will be displaced to the north/northeast of the area.
Strong moisture advection from the remnants of this storm combined with a trough situated off the PACNW coast, have allowed for deep moisture to to build across the state. As we move through the day today, we will see large-scale ascent take place as the trough to our west starts to approach the region. By Saturday, the trough starts to push eastward, and this will help to shift the areas of heavy rain to the east and along with that, the threat for any flash flooding.
Low temperatures will be slower to respond with readings mostly in the low 60s tonight into Saturday morning.
Today, the aforementioned wave drops south and east, pressing the current wave of rain eastward through the day before ultimately tapering off with the system's dry slot/cold front. As lake enhanced inversion heights decrease tonight as ridging and high pressure filter in from the west, expect a decrease to any showers or upslope enhancement. After rain wraps up, expect dry weather into the weekend as a ridge builds over the area once more.
WEATHER PATTERN OVERVIEW: Upper ridge over the region will slowly slide east over the next few days as upper low moves into the Pacific Northwest. With high pressure over the Dakotas, southeast winds will increase today so have issued a Lake Wind Advisory for Fort Peck Lake. Unseasonably warm temperatures will peak on Saturday before the ridge exits eastward.
438 AM CDT Fri Oct 10 2025 - Dry and cooler conditions expected for Friday with highs in the mid to upper 70s and northeasterly winds at 10 to 15 mph.
* A cold front Saturday morning will bring cooler temperatures and low chances for light rain/mountain snow showers this weekend. Breezy to windy conditions persist early this morning across much of the region as the first of a series of upper level lows that will be affecting us for the next seven days arrives today. Its associated cold front will push through the region tomorrow, Saturday. Rain arrives to our area late this afternoon and early evening as the cold front starts to push through the area over portions of NE CA. So, snow will be restricted to the highest elevations of mountains with amounts below 0.
918 AM EDT Fri Oct 10 2025 High pressure will shift slowly east through the weekend. Temperatures will be a tad warmer with afternoon highs in the upper 60s to lower 70s. The closed low will be moving off toward northeast Ohio at the start of the extended and will be in the process of being absorbed by a broader area of low pressure off of the Atlantic coastline. Closer to the surface, a weak cold front will be pulled through the region, though sensible impacts will be minor and any isolated showers will taper off by the overnight. Meanwhile, to our northwest, a robust area of low pressure will be moving through southern Canada, allowing for continued warm air advection.
614 AM EDT Fri Oct 10 2025 High pressure will shift slowly east through the weekend. Temperatures will be a tad warmer with afternoon highs in the upper 60s to lower 70s. The closed low will be moving off toward northeast Ohio at the start of the extended and will be in the process of being absorbed by a broader area of low pressure off of the Atlantic coastline. Closer to the surface, a weak cold front will be pulled through the region, though sensible impacts will be minor and any isolated showers will taper off by the overnight. Meanwhile, to our northwest, a robust area of low pressure will be moving through southern Canada, allowing for continued warm air advection.
As the system begins to take shape today, an elongated trough axis is expected to be present across the southern half of Florida and will likely be the focus for convection through the entire day. With PWATs on the upper end of climatology and weak/variable flow near the trough axis, slow moving storms capable of producing heavy rain will be possible today.
612 AM EDT Fri Oct 10 2025 Cool and dry high pressure lingers over the region today with below normal temperatures sticking around.
514 AM MDT Fri Oct 10 2025 - Scattered showers and isolated thunderstorms today and Saturday, mainly across the higher terrain.
(Rest of today through Saturday) Clouds associated with a low pressure system and attending cold front are beginning to inch closer to the mid-state this afternoon. We do not expect any precipitation from the cold front, as it should stall out north of our area. (Saturday Night through next Friday) Into the work week, a high pressure system is forecasted to be the dominant feature, leading to the increase in our temperatures. They will level off in the low 80s for highs by mid-week, with morning lows in the low to mid 50s. High pressure also means no precipitation in the forecast for the period, so things will remain dry.
In the middle though, the sweet spot east of the I-17 corridor, this is where this highest overall totals will occur. As the front/trough axis pushes the sub-tropical plume east and southeast Saturday, the atmosphere destabilizes as the upper levels dry out.
A cold front analyzed on the 19z/2pm surface map extending from Wisconsin into eastern Iowa will drop slowly southeastward this evening. Overnight lows will range from the middle to upper 40s in the Illinois River Valley to the lower 50s elsewhere. After some lingering cloud cover in the morning, skies will become mostly sunny across the board by Saturday afternoon with highs topping out in the lower to middle 70s.
- Dry and mild conditions are anticipated through the weekend thanks to cooler airmass in place and high pressure overhead.
A large area of high pressure will build into the Upper Midwest and western Great Lakes area tonight, leading to light N to NE winds and cool temperatures.
1225 PM CDT Fri Oct 10 2025 - Cooler today, but overall above normal temperatures will persist into this weekend.
* A cold front Saturday morning will bring cooler temperatures and low chances for light rain/mountain snow showers this weekend. Breezy to localized windy conditions will prevail once again this afternoon ahead of an incoming cold front set to push through Saturday morning. Sierra ridgetop gusts could also exceed 80 mph. A cold front will approach NE California this evening and pass through W. Lows are expected to be well below freezing across the Sierra and NE California. Meanwhile, rural valleys across western Nevada will also approach freezing.
Mid-upper level high pressure over Mexico and Texas will continue to be the dominant weather feature, resulting in very low chances for rain over Southeast Texas through the next several days. The high temperatures over the weekend will generally be in the upper 80s to lower 90s inland and in the mid to upper 80s along the coasts.
1220 PM CDT Fri Oct 10 2025 - Dry weather conditions with cooler mornings will prevail through this weekend. High pressure ridging and light northerly flow will continue tonight and Saturday, under mainly clear skies. Expect slightly warmer highs on Saturday, climbing into the low to mid 80s. /15/ The building upper ridge combined with drier air advecting across the southeast CONUS will allow for dry and quiet conditions to persist across our CWA through the weekend.
* Dry conditions are expected through the weekend with highs in the low to mid 70s.
Cloud cover overnight should keep overnight lows quite a bit warmer tonight than last night with lows in the 50s. High pressure builds back into the Great Lakes for the weekend switching flow around to the northeast. The frontal passage from overnight should not have any impact on temperatures as low level cooler air will remain north of the region. With clearing skies and better surface heating, high temperatures in the lower to mid 70s are likely across Central Indiana.
202 PM EDT Fri Oct 10 2025 High pressure will provide dry and cool conditions through Saturday. Strong high pressure will keep dry and cool weather conditions through tonight. Expect near above normal temperatures with lows ranging from the mid to upper 40s across the lowlands, to the mid 30s across the northeast mountains. Highs on Saturday will be in the low to mid 70s across the lowlands, ranging into the mid 50s northeast mountains. High pressure system remains in control of the weather pattern through Saturday night.
143 PM EDT Fri Oct 10 2025 High pressure over the Northeast United States will continue east today and move off the New England coast tonight. A low pressure system will move southeast through the Great Lakes region on Saturday and weaken into a trough on Saturday night.
- Forecast uncertainty increases mid-week ahead of a Pacific cold front. A cold front pushes south through central KS, serving as a focal point for some isolated shower development this afternoon. It's more of a moisture boundary than a cold front though, with temperatures in the 80s in the clear skies behind the boundary, and only in the upper 50s to mid 60s under the cloudy skies ahead of it; wind shifts and dew points in the 40s are what give the boundary away. Warm, above-normal temperatures from the upper 70s to mid-80s will occur this weekend beneath a building upper-level ridge. A low pressure system that is currently barreling into the Cascades will attempt to undercut the building ridge in the central US, with a Pacific cold front surging ahead of it.
1239 PM MDT Fri Oct 10 2025 - Scattered showers and isolated thunderstorms today and Saturday, mainly across the higher terrain.
1203 PM CDT Fri Oct 10 2025 - Dry weather conditions with cooler mornings will prevail through this weekend. High pressure ridging and light northerly flow will continue tonight and Saturday, under mainly clear skies. Expect slightly warmer highs on Saturday, climbing into the low to mid 80s. /15/ The building upper ridge combined with drier air advecting across the southeast CONUS will allow for dry and quiet conditions to persist across our CWA through the weekend.
(Tonight) Currently, mid/upr ridging is stretching across the TN Valley, along with generally light NE-E low-lvl flow near the sfc. Lows tonight will be near seasonal norms, in the low to mid 50s.
Highs today will only warm up a few more degrees with those in our SW areas seeing the low 80s today. Another cool night is in store with lows dropping into the low to mid 50s. A ridge to our west will begin to shift our way over the next couple days so we can expect a dry forecast to continue due to little moisture and increased subsidence.
1234 PM EDT Fri Oct 10 2025 High pressure over New England continues dry and cool conditions through Saturday. Rain chances rise Saturday night and remain through the early week especially across the eastern ridges as a weakening Great Lakes low combines with a developing coastal storm. - Warmer overnight temperatures than previous nights. --------------------------------------------------------------- High pressure weakens some and is shunted east through the day as the upper ridge axis moves off the Eastern Seaboard. Winds will be light and largely southerly across the region owing to the retreating high pressure. Southerly winds are expected to persist overnight and hamper efficient radiative cooling, kicking the low temperatures back up into the low 40s ending our frost/freeze concerns. Cloud cover is also expected to increase overnight ahead of an approaching trough moving in from the northwest.
102 PM EDT Fri Oct 10 2025 High pressure will shift slowly east through the weekend. As the closed low exits off to the northeast, a very weak surface front will move through the middle and upper Ohio Valley. However, with heights on the rise, it's tough to call it a cold front. Mid-level ridging centered over the southern plains will continue to nose into the Ohio Valley as we head into next work week.
(This evening through Saturday night) An upper level ridge encompasses much of the center of the country with the axis extending from south Texas to North Dakota. A deep upper low is just now entering the Pacific NW. To the east of the ridge are 2 upper lows, one weaker one centered over Georgia and deeper one near the Great Lakes. The CWA is right on the eastern periphery of that ridge envelope but moreso under general troughing to the east of it.
1209 PM CDT Fri Oct 10 2025 - Dry and cooler conditions expected for Friday with highs in the mid to upper 70s and northeasterly winds at 10 to 15 mph.
- Dry weather conditions with cooler mornings will prevail through this weekend. Have lowered overnight lows just a bit based on recent cooler obs/ guidance trends. /EC/ High pressure ridging and light northerly flow will continue tonight and Saturday, under mainly clear skies. Expect slightly warmer highs on Saturday, climbing into the low to mid 80s. /15/ The building upper ridge combined with drier air advecting across the southeast CONUS will allow for dry and quiet conditions to persist across our CWA through the weekend.
557 PM MDT Fri Oct 10 2025 - Scattered showers and isolated thunderstorms through Saturday, mainly across the higher terrain.
613 PM CDT Fri Oct 10 2025 - Dry and mild conditions are anticipated through the weekend thanks to cooler airmass in place and high pressure overhead.
625 PM CDT Fri Oct 10 2025 - Dry weather conditions with cooler mornings will prevail through this weekend. High pressure ridging and light northerly flow will continue tonight and Saturday, under mainly clear skies. Expect slightly warmer highs on Saturday, climbing into the low to mid 80s. /15/ The building upper ridge combined with drier air advecting across the southeast CONUS will allow for dry and quiet conditions to persist across our CWA through the weekend.
651 PM CDT Fri Oct 10 2025 (Tonight) Currently, mid/upr ridging is stretching across the TN Valley, along with generally light NE-E low-lvl flow near the sfc. Lows tonight will be near seasonal norms, in the low to mid 50s.
734 PM EDT Fri Oct 10 2025 High pressure will drift east off the coast of New England tonight.
738 PM EDT Fri Oct 10 2025 High pressure will shift slowly east through the weekend. As the closed low exits off to the northeast, a very weak surface front will move through the middle and upper Ohio Valley. However, with heights on the rise, it's tough to call it a cold front. Mid-level ridging centered over the southern plains will continue to nose into the Ohio Valley as we head into next work week.
739 PM EDT Fri Oct 10 2025 High pressure will provide dry and cool conditions through Saturday. Strong high pressure will keep dry and cool weather conditions through tonight. Expect near above normal temperatures with lows ranging from the mid to upper 40s across the lowlands, to the mid 30s across the northeast mountains. Highs on Saturday will be in the low to mid 70s across the lowlands, ranging into the mid 50s northeast mountains. High pressure system remains in control of the weather pattern through Saturday night.
357 PM MDT Fri Oct 10 2025 - Scattered showers and isolated thunderstorms through Saturday, mainly across the higher terrain.
Scattered showers and embedded thunderstorms continue across the area as a cold front moves through. Saturday night precipitation chances rise and snow levels fall to 5500-6500 ft MSL, bringing snow to ridges and high elevation passes with a couple inches of snow forecast in mountains.
Updates this evening have been made to track more closely the cloud cover associated with an approaching cold front, with a band of clouds preceding the front, eventually stalling out over central and southeast IL, and gradually dissipating and shifting southward in the morning. Lows in the lower 50s most areas look on track, while Galesburg area in the mid 40s also looks good where more clearing takes place. 37 A cold front analyzed on the 19z/2pm surface map extending from Wisconsin into eastern Iowa will drop slowly southeastward this evening. Overnight lows will range from the middle to upper 40s in the Illinois River Valley to the lower 50s elsewhere. After some lingering cloud cover in the morning, skies will become mostly sunny across the board by Saturday afternoon with highs topping out in the lower to middle 70s.
(Sunday night through next Saturday) By Sunday, the upper level ridge over the area tonight will be weakening as the strong trough over the Pacific Northwest moves into the western CONUS. One is lee troughing along the eastern slopes of the Rockies, which will tighten surface pressure gradients in the southern plains, increasing south to southwesterly winds in our area.
1215 AM MDT Sat Oct 11 2025 - Scattered showers and isolated thunderstorms through Saturday, mainly across the higher terrain.
(Through Saturday) Upper ridge in control across the southern Plains today.
In the upper levels, a trough is lingering over the Southeast as a cut-off low moves into the Northeast. A ridge extends from Texas to the Midwest. At the surface, high pressure over the Northeast is moving out quickly as a low starts to develop off the Southeast Coast.
Did elect to lower dewpoints this afternoon with forecast soundings in agreement with a stripe of upper 30 to low 40 degree dewpoints generally along I-85 and on the western side of the coastal low but the eastern side of the trough over northern AL. Current forecasted highs will be in the low to mid 70s with lower amounts on the eastern third of the CWA. Temps warm to near 80 for Sunday as we become further removed from the high level cirrus deck and showers.
A cold front continues to make slow progress southward early this morning, and as of 1 AM, this weakly convergent boundary is located near Highway 34 in Illinois. North of the front, much drier air is allowing for strong cooling, and we're starting to see some low lying areas drop to the lower 40s already as of 1 AM, thus lows in the upper 30s to low 40s look on target north of I-80, and mid to upper 40s farther south. Tonight, low pressure developing in the Plains will tighten the pressure gradient slowly overnight, but the dry air should still allow for lows in the mid 40s east to near 50 west. Sunday, strong low pressure is expected to move through southern Canada, out of the northern Plains states, resulting in a breezy day, especially western areas, during the afternoon.
215 AM EDT Sat Oct 11 2025 Low pressure moves in today with increasing clouds as well as precipitation chances this afternoon and evening.
High pressure moves eastward and low pressure deepens over the Northern High Plains today to create a strengthening low-level southerly jet over the Upper Midwest and Northern Plains.
