1011 PM CDT Mon Oct 6 2025 - Freezing temperatures are expected in western and north central North Dakota tonight. This is in line with going forecast with freezing temperatures expected later tonight. With high pressure moving across the region, clear and dry weather is anticipated today. With clear skies and relatively weak winds tonight, another round of freezing temperatures is anticipated over the northern and portions of southwestern North Dakota through Tuesday morning, dropping as low as 28.
1052 PM MDT Mon Oct 6 2025 - Cold, near to below freezing, temperatures tonight.
1000 PM PDT Mon Oct 6 2025 * Dry conditions and a warming trend are expected through midweek as high pressure builds across the region.
(Through Tuesday) Progression of the cold front has trended faster than forecast, and currently extends from Pawnee to Norman to Tipton.
- A pattern shift is expected by late this weekend, bringing cooler temperatures and additional precipitation chances. What happens, though, is that the ridge gets shoved eastward over the Northern Plains. Right now it looks like we'll see the Aleutian Low deepen southward along the West Coast through the week, serving to amplify the ridge over the south-central CONUS.
A weakening low pressure center over SEMO/western KY this morning is progged to drift gradually east and northeastward through the day. The combination of forcing with the low and the added moisture continues to lead to widespread rain across the area. This will also be ahead of a cold front that stretches from Quebec south and southwest to central Texas this morning.
223 AM EDT Tue Oct 7 2025 A passing cold front will bring widespread rain to the area today, as well as a few storms in the afternoon.
1031 PM MDT Mon Oct 6 2025 - Widespread below freezing temperatures again tonight into Tuesday morning. Afternoon satellite imagery shows mostly clear skies across much of eastern Idaho aside from some fair weather CU forming across the higher terrain of the central mountains and eastern highlands. Temperatures remain on the cooler side of normal this afternoon with widespread upper 40s to mid 50s across the region. The cooler temperatures are the only weather concern in the short-term as another night of sub-freezing temperatures appear likely across our agricultural zones. Tue night into Wed AM looks like it'll be a touch warmer but still may require some frost/freeze headlines in spots.
1254 AM CDT Tue Oct 7 2025 - Freezing temperatures in western and north central North Dakota tonight. Temperatures continue to fall below freezing in the west and north central. This is in line with going forecast with freezing temperatures expected later tonight. With high pressure moving across the region, clear and dry weather is anticipated today. With clear skies and relatively weak winds tonight, another round of freezing temperatures is anticipated over the northern and portions of southwestern North Dakota through Tuesday morning, dropping as low as 28.
257 AM MDT Tue Oct 7 2025 - Freeze warning in effect for Snake River Plain this morning with widespread below freezing temperatures through the early morning hours.
Most of the high-res guidance has been hinting at showers and storms flaring up over the Gulf and near the coastline throughout the overnight and early morning hours. As we roll toward the afternoon hours, some of the high-res guidance lights up across parts of southeast MS and southwest AL between 19- 23z, especially for locations west of I-65.
- Drier conditions with cooler mornings will return during the latter half of this week.
233 AM CDT Tue Oct 7 2025 - Although the risk is very low (<10% probability), very isolated patchy frost may occur tonight in favored cold areas in the highway 20 corridor.
Surface ridging will be sliding through the forecast area at the surface, keeping winds light.
Skies should clear out this afternoon, but despite the sunshine, it'll be much cooler today with highs generally in the 60s.
225 AM CDT Tue Oct 7 2025 - Scattered showers and thunderstorm continue north of I-72 and south of I-70 into this afternoon as the cold front exits central and southeastern IL this afternoon.
Updated at 138 AM CDT Tue Oct 7 2025 - A cold front is expected to approach the area today, bringing cooler temperatures areawide and chances (10-35%) of isolated showers/storms across southeast New Mexico.
237 AM EDT Tue Oct 7 2025 Upper ridging remains over the Gulf Region into the W Atlantic keeping deep tropical moisture over most of the state through mid week. The moderately tight pressure gradient continues between high pressure in the Western Atlantic to Mid Atlantic region and a stalled frontal boundary over the Bahamas and S FL with occasionally gusty easterly winds and a choppy sea state.
-The greatest area for measurable precipitation will be across eastern Arkansas where some locations may see an additional tenth to quarter inch of rainfall today with the highest additional amounts between a quarter inch to half inch of rainfall in a few isolated locations across eastern Arkansas and far northeastern Arkansas where the highest additional rainfall amounts are anticipated. -Cooler and more seasonal conditions should return by mid to late week,in the wake of a cold front that will move across the state later today from northwest to southeast, with settled weather prevailing thereafter. TUESDAY INTO TUESDAY NIGHT: An upper lvl broad, positively-tilted trof over the northern Plains region of the CONUS combined with an inverted trof of low pressure at the sfc will advect moist southerly to southeasterly flow into Arkansas.
1237 AM CDT Tue Oct 7 2025 A weak upper Atlantic ridge will build eastward over the Deep South and northern Gulf through Tuesday as the long wave trough passes over the Great Lakes and Ohio River Valley Tuesday night.
Temperatures are sitting mostly in the lower 80s, but a few showers that have just crossed the Marathon area have brought temperatures there down into the upper 70s. An area of low pressure is idling over the Bahamas, but it's important to note that this is not an area of tropical interest. The slow progression of this low means that persistent, steady rainfall will be possible.
Temperatures this morning will range from the low to mid 20s west of the Divide and upper 20s to lower 30s east of the Divide. Fortunately, a warming trend is on its way as the cold Canadian air mass is ushered to the east and high pressure builds in over the Intermountain West. Highs today will still be on the cooler side with temperatures in the mid to upper 50s. However, warmer temperatures settle in for Wednesday with highs returning to the upper 60s to lower 70s. Warm and dry conditions persist through the remainder of the work week as high pressure sits over the region. Looking ahead, long range models are showing a rather potent cut-off low developing off the coast of the PACNW during the middle of the week.
A flattening upper-level ridge of high pressure is in place over the Pacific Northwest. Beneath the ridge, clear skies coupled with predominantly light winds and a dry air mass (PWATs of 0. Isolated near-freezing temperatures are expected (80% confidence) this morning for low- lying, cold-prone locations within the Yakima and Kittitas valleys, Columbia Basin, and along the Blue Mountain foothills; no Freeze Warnings have been issued due to limited spatial extent. Elsewhere, more widespread sub- freezing temperatures are expected (80-100% confidence) this morning for central Oregon, the John Day Basin, and the Grande Ronde and Wallowa valleys. Looking ahead, a couple vort lobes are progged to drop south from the Gulf of Alaska and BC and carve out an offshore closed low today through Wednesday.
As of 2 AM a surface cold front is draped from Pittsfield, IL to Mexico, MO and making its way southeast through the forecast area. At the same time a mid-level trough will exit the Mississippi Valley while a ridge builds into the Central Plains in its wake, leaving the region within northwest flow aloft for Wednesday.
- Cooler temperatures this week with afternoon highs in the 70s and overnight lows in the 40s and 50s. As this low moves north, it will eventually collide with the incoming cold front, pushing a plume of higher moisture across northwest Middle TN with PWATs near 2". 1" to 3" is likely in total by tomorrow night with the highest totals falling across the northwest portion of the CWA. For convective coverage, 00Z CAMs are initializing a narrow band of thunderstorms just ahead of the cold front Tuesday afternoon and evening. The front will clear the area early Wednesday, ushering in a drier and cooler airmass.
The bigger impact from this front will be the cooler, drier air that advects into the area from central Canada. Surface ridging settles over the area tonight, with calming surface winds, light boundary layer winds, and clear skies. This setup promotes good cooling, and expect below-freezing temperatures areawide. Cannot rule out mid 20s in the typically cooler spots. Surface ridging moves to the east Wednesday, allowing for a return to southerly flow. The airmass will modify through the rest of the week, with daytime temperatures warming into the 60s by the end of the week, and overnight lows back above freezing each night.
538 AM CDT Tue Oct 7 2025 - Although the risk is very low (<10% probability), very isolated patchy frost may occur tonight in favored cold areas in the highway 20 corridor.
500 AM CDT Tue Oct 7 2025 - Early morning showers and storms - Drier and warmer through the rest of the week A mid level wave is currently moving across the greater region early this morning. Once again, took the cooler side of high temperature guidance with the lingering cloud cover around. Lows tonight should range from the upper 40s north to the lower 50s south.
(Today through Wednesday) An upper level ridge extends from a high off the east coast to TX tonight with west-southwesterly flow at 500mb. There is a cold front moving down through the Texas Panhandle tonight. Today the low level flow will become better established from the southeast and bring moister air into the region. Temperatures over the Coastal Plains may be a couple of degrees warmer with the southeasterly flow, and the approaching front from the north may keep highs a couple of degrees cooler across the northern counties.
609 AM CDT Tue Oct 7 2025 Updated at 604 AM CDT Tue Oct 7 2025 - Cooler temperatures today and Wednesday following the passage of a cold front. (Today) A cold front will continue moving south across the area today, with cooler temperatures following in its wake. Afternoon high temperatures will range from the lower 70s near the Kansas border to the upper 80s near the Red River.
924 AM EDT Tue Oct 7 2025 High pressure will remain northeast of the area through Wednesday.
613 AM CDT Tue Oct 7 2025 Updated at 612 AM CDT Tue Oct 7 2025 - Showers and thunderstorms will persist along with cooler temperatures through Wednesday. - Drier and warmer conditions are expected late week with an increase in fire weather concerns over the weekend.
604 AM CDT Tue Oct 7 2025 Updated at 603 AM CDT Tue Oct 7 2025 - A cold front is expected to approach the area today, bringing cooler temperatures areawide and chances (10-35%) of isolated showers/storms across southeast New Mexico. (Today through Wednesday afternoon) WV imagery this morning shows the upper trough still off the California, with Hurricane Priscilla churning south of Baja. Farther east, West Texas and Southeast New Mexico are under southwest flow aloft on the northwest periphery of a ridge centered over the Gulf Coast states. To the north, mesoanalysis shows a cold front entering the South Plains, and local surface winds are already backing to east as a result. Even so, this is about 5 F cooler than yesterday.
601 AM CDT Tue Oct 7 2025 - Scattered showers and thunderstorm continue north of I-72 and south of I-70 into this afternoon as the cold front exits central and southeastern IL this afternoon.
Most of the high-res guidance has been hinting at showers and storms flaring up over the Gulf and near the coastline throughout the overnight and early morning hours. As we roll toward the afternoon hours, some of the high-res guidance lights up across parts of southeast MS and southwest AL between 19- 23z, especially for locations west of I-65. Forcing for showers and storms remains minimal again on Wednesday as the ridge aloft continues to slide westward across the Gulf.
(Today and tonight) A weak cold front will move south across the Big Country in the early to mid-morning hours, and should reach a San Angelo to Richland Springs line by early afternoon. Temperatures will be several degrees cooler today in the Big Country, where highs in the 80s are expected. For areas farther south, temperatures will only be a few degrees cooler today with highs mostly in the mid to upper 80s.
Skies should clear out this afternoon, but despite the sunshine, it'll be much cooler today with highs generally in the 60s. Weak secondary cold front will move south down the lake tonight and across our CWA late tonight/early Wednesday morning.
A weak cold front upstream in the Northern Plains will move eastward through Lake Superior today and the resultant increasing pressure gradient and post frontal cold air advection will enable gusty winds to develop across the region. The airmass will continue to dry through the day as high pressure presses eastward into the area and subsidence increases. For the Keweenaw and east, went with a frost advisory given the slightly warmer anticipated temperatures.
418 AM PDT Tue Oct 7 2025 * Dry conditions and a warming trend will continue today and Wednesday as high pressure builds across the region.
Surface ridging will be sliding through the forecast area at the surface, keeping winds light. The previously mentioned surface ridging will slide east of the Northern Plains on Wednesday, resulting in a tightening of the surface pressure gradient. As of now, the lowest relative humidity (RH) values look to occur east of I-29.
652 AM EDT Tue Oct 7 2025 A passing cold front will bring widespread rain to the area today, as well as a few storms in the afternoon.
625 AM EDT Tue Oct 7 2025 High pressure will remain northeast of the area through Wednesday.
642 AM MDT Tue Oct 7 2025 - Freeze warning in effect for Snake River Plain this morning with widespread below freezing temperatures through the early morning hours.
732 AM EDT Tue Oct 7 2025 - Showers linger today along slow-moving front - Frost/Freeze for Tonight, Wednesday night - Showers linger today along slow-moving front The upper ridging of the past week is being replaced by a trough moving through the next couple days. An axis of marginal instability along with deep layer shear of 25 to 30 knots will be along southern Lower Michigan early this morning and transient bowing line segments could bring an isolated wind threat before the surface cold front clears that area.
910 AM CDT Tue Oct 7 2025 Updated at 903 AM CDT Tue Oct 7 2025 - Cooler temperatures today and Wednesday following the passage of a cold front. Cold front has pushed south of the Interstate 44 corridor and will continue to make steady progress southeastward through the day. (Today) A cold front will continue moving south across the area today, with cooler temperatures following in its wake. Afternoon high temperatures will range from the lower 70s near the Kansas border to the upper 80s near the Red River.
- Cooler weather moves in for a couple days before temperatures warm back above seasonal averages. The 850mb cold front which is partially sustaining these storms is slowly working its way toward the south and east with storms expecting to follow along with it as it progresses. Movement of the front starts to accelerate around 3-5 AM as the 500mb jet begins to migrate southward being pushed along by a ridge migrating into the region. Cool stable air combined with this ridging brings temperatures back down to more seasonal level with highs in the upper 60s to near 70 degrees. The cool down doesn't last very long as a longwave ridge maneuver through the central CONUS midweek.
- Scattered showers with isolated lightning ending around to just after sunrise today, then drying with slightly warmer temperatures.
Mobridge reported a light sprinkle, so continued that across the CWA. Highs today in the low to mid 60s as one high pressure departs with a second moving into the Red River valley this evening.
WEATHER PATTERN OVERVIEW: Upper ridge over the Pacific Northwest will gradually slide eastward over the next few days. As flow into the region turns southwest, warmer air will spread into the northern plains. The eastward shift of the ridge will be aided by an deepening upper trough over the Pacific Northwest. This system will slide east for cooler temperatures and wet weather chances increasing by the weekend.
625 AM CDT Tue Oct 7 2025 - Isolated showers and storms will be possible along the coast and in the Gulf waters through the next several days - Hazardous marine conditions possible later in the week due to increasing winds High pressure continues to build into the state, resulting in a rather benign pattern for inland areas. A weak boundary will move in from the north later in the week, bringing drier and slightly cooler weather for the weekend. Afternoon highs through mid-week will run above normal with temperatures in the low to mid 90s and overnight lows in the low to mid 70s. Following the passing of the weak frontal boundary, daytime highs will be in the upper 80s to low 90s with overnight lows in the low to mid 60s.
1222 PM CDT Tue Oct 7 2025 Updated at 1221 PM CDT Tue Oct 7 2025 - A cold front is expected to approach the area today, bringing cooler temperatures areawide and chances (10-35%) of isolated showers/storms across southeast New Mexico. (Today through Wednesday afternoon) WV imagery this morning shows the upper trough still off the California, with Hurricane Priscilla churning south of Baja. Farther east, West Texas and Southeast New Mexico are under southwest flow aloft on the northwest periphery of a ridge centered over the Gulf Coast states. To the north, mesoanalysis shows a cold front entering the South Plains, and local surface winds are already backing to east as a result. Even so, this is about 5 F cooler than yesterday.
1103 AM CDT Tue Oct 7 2025 - Early morning showers and storms - Drier and warmer through the rest of the week A mid level wave is currently moving across the greater region early this morning. Once again, took the cooler side of high temperature guidance with the lingering cloud cover around. Lows tonight should range from the upper 40s north to the lower 50s south.
From synopsis, a combination of a stationary frontal boundary and a weak area of low pressure still situated near the Bahamas will make for a messy weather pattern through the next several days.
158 PM CDT Tue Oct 7 2025 - Lingering low clouds will occur into this evening and overnight in the wake of this mornings cold front.
A cold front pushed pushed through the western U. A secondary cold front will drop south through the U. P this evening bringing another surge of cooler air into the region. The trough axis shifts east of the area late in the week as a ridge of high pressure builds into the western U.
- A cold front will pass through the region tonight, bringing cooler temperatures for the remainder of the week.
(This evening through Wednesday) A weak cold front is currently located across central portions of the area. Little change in temperature is expected behind the front, with highs across the Big Country a few degrees cooler than what we experienced yesterday. Overnight lows will be in the low to mid 60s. On Wednesday, the aforementioned remnant weak cold front will be located across our southern counties.
335 PM CDT Tue Oct 7 2025 - Increasing cloud coverage across southwest into central Nebraska will hold highs in the lower 60s across these areas Wednesday.
- Drier conditions with cooler mornings will return during the latter half of this week. The semi-permanent subtropical ridge that has largely controlled the weather over our region the past few weeks will continue to be the primary influence for us going through the remainder of the week and into the weekend. Through tonight: Scattered light showers associated with a weak cold front pushing slowly southeast into the area will diminish quickly with sunset.
327 PM EDT Tue Oct 7 2025 - Frost/Freeze for Tonight and Wed Night, Chance Frost Thu Night - A Little Warmer and Mostly Dry Late Week into the Weekend - Frost/Freeze for Tonight and Wed Night, Chance Frost Thu Night Frost and some spots of 2-meter temperatures near 32 are anticipated tonight in the highlands of interior central Michigan, mainly northern Newaygo, Mecosta, northwest Isabella counties and northward.
1143 AM MDT Tue Oct 7 2025 - Freeze warning in effect for Snake River Plain this morning with widespread below freezing temperatures through the early morning hours.
209 PM EDT Tue Oct 7 2025 A passing cold front will bring widespread rain this afternoon through tonight. This front will be followed by dry and cooler weather through this weekend.
1211 PM CDT Tue Oct 7 2025 - Scattered showers and thunderstorm continue north of I-72 and south of I-70 into this afternoon as the cold front exits central and southeastern IL this afternoon.
300 PM CDT Tue Oct 7 2025 - Mostly dry weather and cooler (more seasonable) temperatures are expected through the remainder of the work week. A much cooler airmass has moved into the region in the wake of a cold front with temperatures back to more seasonable levels (to even slightly cooler than normal).
-Cooler temperatures and much drier air will be seen in the coming days. TUESDAY INTO TUESDAY NIGHT: An upper lvl broad, positively-tilted trof over the northern Plains region of the CONUS combined with an inverted trof of low pressure at the sfc will advect moist southerly to southeasterly flow into Arkansas.
Scattered showers will end this evening with only isolated showers expected on Wednesday as an upper ridge builds westward across the southeast states.
(Rest of today and tonight) A few more breaks in the clouds than previously thought, however still think even with the erosion of the lowest clouds, there will remain quite a bit of mid/high clouds to limit insolation today. Temps have trended cooler as well and much of the north and perhaps even southward toward I-40 may struggle to climb out of the 60s this afternoon. However, cooler, drier airmass will allow temperatures to drop into the 50s across much of the area with a few low 60s along the Red river.
111 PM PDT Tue Oct 7 2025 * Dry conditions and a warming trend will continue today and Wednesday as high pressure builds across the region.
These showers are all occurring out ahead of a slow moving cold front that based on sfc obs is located just east of Memphis. Heading into the overnight hours, the aformentioned cold front continues to shift southeast towards the local forecast area.
154 PM CDT Tue Oct 7 2025 - Scattered showers and thunderstorm continue north of I-72 and south of I-70 into this afternoon as the cold front exits central and southeastern IL this afternoon.
Even with lowering temperatures to the NBM50th percentile, most areas remain above freezing tonight.
(Tonight through Wednesday night) An increase in moisture is seen this afternoon ahead of the main cold front currently draped across North Texas which will bring low rain chances to the area through tomorrow. The cold front will slowly move south today before stalling this evening.
Dry/cooler conditions expected beyond midweek. (This evening through Wednesday night) An upper level trough is currently moving east across the Great Lakes region with the base extending south to around Tennessee. A plume of higher atmospheric moisture content stretches from the north-central Gulf to around the apex of that trough.
