This dry layer has shown up on high- elevation, ridgetop surface observations (RAWS and CWOP) to the tune of dew points in the -15 to -30 degrees Fahrenheit range. It's a different story in the lower levels with nighttime microphysics RGB imagery showing fairly widespread low stratus peaking out beneath scattered to broken cirrus.
(Today through Sunday) High pressure over the TN valley early this morning will shift east towards the Mid Atlantic region today and eventually move off the coast by this evening. Low temps tonight will be in the low to mid 60s around the lake and SW FL, to upper 60s and low 70s across the east coast metro. Sundays high temps will be in the low to middle 80s.
516 AM CST Sat Nov 29 2025 - Rain returns to the forecast this today with an approaching cold front/upper level disturbance from the west.
Obs indicate vsbys are in the 1-3SM range and DOT webcams indicate a steady snow, but snow itself is quite fluffy and from what I can tell flake size is small, outside of the highest return areas.
Currently, upper level S/WV trough developing east into the Dakotas early this morning, with its associated 700mb low pushing south into north central/northeastern South Dakota.
340 AM MST Sat Nov 29 2025 - Snow returns this evening and lasts into Sunday afternoon - Bulk of the precipitation with this round is along the 84/86 corridor and south into the higher elevations.

A strong cold front is forecast to push across the local area Saturday night through early Sunday.
528 AM CST Sat Nov 29 2025 - Gusty north-northeast winds are expected this evening and Saturday night following a cold frontal passage. A developing low pressure system over the central Plains was resulting in strong southerly flow which is bringing in plenty of low-level moisture to the region. Some locations in the Big Country will drop below freezing.
Light snow continues most areas, as the main upper level trough approaches the region, with the more defined radar returns over south central and southeastern North Dakota. Currently, upper level S/WV trough developing east into the Dakotas early this morning, with its associated 700mb low pushing south into north central/northeastern South Dakota.

The track of the low comes right across eastern Idaho, which is very similar to the forecast track over the past couple of days.
The trough that has supported snowfall from last night through today will push southeast of the state by early evening. Wind speeds will be on the lighter side as the high moves overhead, resulting in wind chills/apparent temps as low as 25 below zero for some locations tonight and Sunday night (not reaching criteria for any headlines).
Updated at 1211 PM CST Sat Nov 29 2025 - Cold and windy conditions return this afternoon and tonight behind a cold front.
Strong winds will also continue through the afternoon as the low continues to deepen to the east. Brief high pressure will build in from the north on Sunday allowing for a dry forecast to return. The colder airmass will keep temperatures on the cooler side, though, with highs only rising into the 20s.

506 PM CST Sat Nov 29 2025 Updated at 504 PM CST Sat Nov 29 2025 -A strong cold front moves through today, bringing falling temperatures and gusty north winds.
1007 PM PST Sat Nov 29 2025 Ceilings will remain in the LIFR and IFR categories for many of the terminals overnight as the areas recovers from as weak upper trough overspreading a cold surface airmass. PSC was a little warmer resulting in the rain precipitation type. Even then, guidance generally only depicts about an inch or two of snow accumulations along the ridgetops of the southern Blues, with a hotspot around the Strawberries. Transitory ridging then moves in late Sunday into Monday, bringing with it the potential for more low clouds and fog in the Basin.
(Today through Monday) Warm front will lift north across the area today before settling over northern FL on Monday. High temps this afternoon will range from the lower 80s across the east coast metro to mid 80s over SW FL. Low temps will be mild ranging from the lower 60s around the lake to the lower 70s over SE FL. High temps will again range from the lower 80s across the east coast metro to middle 80s over SW FL.

Issued 232 AM CST Sun Nov 30 2025 Early this Morning through Tonight: Light to moderate snow continues early this morning, as the mid level trough lifts through the region. This Advisory will be in effect through noon for locations along and west of the Highway 26 corridor, and until 3 PM for locations east of there. Skies will partially clear this evening into tonight as high pressure builds southeastward into the area.
944 PM PST Sat Nov 29 2025 Dry and cooler this weekend.
For the moment, the pressure gradient is continuing to drive windy conditions across the Keys, but as the high pulls further away, winds will begin to slacken into Sunday morning. As the front decays and the high shifts northeastward, breezes will begin to slacken by Sunday morning. Another cold front may be on the horizon for the middle of the week, reflected in the breezes turning around the clock ahead of it.
High pressure to our west is still forecast to move in later tonight, diminishing clouds and flurries. The trough that has supported snowfall from last night through today will push southeast of the state by early evening. Wind speeds will be on the lighter side as the high moves overhead, resulting in wind chills/apparent temps as low as 25 below zero for some locations tonight and Sunday night (not reaching criteria for any headlines).
Still looking for unseasonably cold air to spill south tonight, providing single digit wind chills Sun morning and highs on Sun struggling to make it above freezing. GFS and NAM agree on the higher snow totals further north, generally along I-70. Meanwhile, the ECMWF has maintained its further south track and has the higher totals near Highway 50. Meanwhile, a Polar upper low will migrate across Ontario and will keep below normal temps in place from the Plains through the Ohio Valley.
329 AM EST Sun Nov 30 2025 - A cold front passing through today will bring an end to any rain, and keep temperatures from rising much.
Totals have been highest along the Highway 20 corridor so far today with widespread reports of 8-12+ inches. Winds diminish midday Sunday as the low pushes further east, and clouds clear out. The low is set to track across Missouri with the northern deformation zone passing over southern Iowa.
An additional upper-level trough is digging into the northwestern CONUS. At the surface, high pressure has moved into the Northern Plains. Highs will generally struggle to reach above freezing with the upper 20s forecast for central KS and low 30s in south-central to southeast KS. Tonight, the aforementioned upper-level trough over the northwestern CONUS will continue to dig and move southeast into the Central Rockies by Monday morning. This trough will move across our area on Monday, increasing snowfall chances. Snow is forecast to start Monday morning in southern Nebraska and northern Kansas, as lift increases from the upper-trough coupled with the left exit region of upper jet. As the upper low moves southeast into the Mississippi Valley with the low-level trough, snow chances will shift into eastern Kansas and Missouri.
306 AM EST Sun Nov 30 2025 - Transition to lake effect near lake shore today - Accumulating snow possible Monday afternoon/night - Cold week ahead - Transition to lake effect near lake shore today Surface obs reveal low pressure over central Lake MI early this morning. Winds will increase this afternoon as the low moves by and high pressure builds in behind it. - Accumulating snow possible Monday afternoon/night Boundary layer winds will become southwesterly Monday ahead of the next upper trough.
Cooler and drier weather is in store for the majority of the week as high pressure settles into the area. Some weak disturbances may drop into the region on the edge of the ridge but it won't amount to meaningful precipitation accumulation.
A weak cold front will move across northern Arizona late this evening and into tonight. Gusty winds and cooler temperatures are in store for most, with chances for rain and snow showers limited to the Four Corners region.
- Monitoring the potential for light freezing rain over far northwest portions of the area Monday morning.
This will veer winds westerly and in a tightening MSLP gradient south of the low, gusts will likely surge again to 30-35 mph after midnight. Resulting cold advection will push lows to the lower 20s, freezing any water that results from the melting/compaction ongoing this evening. Once low pressure lifts into the Great Lakes and a cold front is pulled through the region, winds will veer to the northwest tonight. particularly where temps remain at or below freezing this evening and the snow surface does not become crusty.
Despite the little cloud cover the lighter winds combined with the core of colder air hanging through western Kansas should allow lows to fall into the lower to mid teens. By late Sunday afternoon a developing storm system in the intermountain west will bring a negative tilt trough into the central plains by mid Monday morning.
1127 PM PST Sat Nov 29 2025 * Temperatures near seasonal averages will persist through early this week with increasing ridge winds starting tonight.
Temperatures today will be in the low to mid 70s across the lower deserts (2-4 degrees above normal) with a case of deja vu on Sunday with almost identical afternoon highs. The system will however drop highs to around 70 degrees and bring some northerly breezy wind across the Lower CO River Valley.
There is a long tail on the high end with about 15 percent of the members showing greater than 0.
Models favor snow for precipitation type, but a wintry mix of snow, light freezing rain, and/or sleet could occur over far southern Missouri. Behind the system that is exiting the area this evening, look for temperatures to drop into the low 20s tonight into Sunday morning. Precip type should be all rain, but a brief period of drizzle is possible on the back side (temperatures will still be above freezing at that time). Also, ptype probabilities shifted slightly from freezing rain toward light sleet over the far south. Highs Monday still look to be in the low 30s.
- Most locations across the northern half of the CWA (and higher elevations) can still expect to see overnight lows at or below freezing tonight and tomorrow night.
525 AM CST Sun Nov 30 2025 Updated at 1041 PM CST Sat Nov 29 2025 - Cold and breezy conditions tonight behind a cold front.
Dry conditions are then anticipated into Monday afternoon as upper-level ridging noses into the Pacific Northwest.
448 AM CST Sun Nov 30 2025 - Winds will calm tonight and lows will drop into the teens with wind chills in the single digits - Cold air continues through Monday - A quick moving system will bring light accumulations of snow to parts of southwest and north central Kansas on Monday The current synoptic pattern is headlined only by a trough along the northern section of the CONUS bringing snow across the majority of midwestern states. Present RAP mesoanalysis has western Kansas dominated by weak ridging that has been building.
A cold front has moved through the area with snow showers confined to the NV border, tapering off by noon.
Winds will stay breezy this afternoon, generally 20-30 mph, but will ease as a secondary trough moves across the Corn Belt, pushing the winter storm further eastward into the Great Lakes. Anticipate low clouds and scattered snow showers near and north of I-74 into the early afternoon as this trough axis crosses into northern Illinois. Winds will then diminish this evening as the trough departs and high pressure moves into the Midwest. Temperatures will fluctuate between very cold and just plain cold throughout the week as high pressure moves in and out of central Illinois.
High pressure over the Pacific Ocean has built a resilient ridge, with the front edge remaining over the area.
The highest accumulations of 2 to 4 inches will occur along and north of a Beardstown to Bloomington line.

Issued 300 PM CST Sun Nov 30 2025 Tonight through Monday night: The low will push out tonight with higher pressure following in behind it which will allow some level of clearing skies tonight. Total QPF on the high end will be between 0. While the DGZ may be fairly deep for a period, there will be limited forcing within the DGZ for most of the event and thus modeled SLRs have a bit on the high side with SLRs likely to be in the 13-15:1 range.
Tonight into Monday morning the longwave trough will move from the four corners region to western Kansas. Ahead of the trough increasing frontogenesis and lift in the dendritic growth zone is forecast to start developing after 06Z in northwest Kansas and quickly spread into north central through southwest Kansas through sunrise.
This is the first of a couple short wave troughs that will influence the Desert Southwest this week and will be to the east of the Four Corners region by Monday afternoon. As this first trough passes some breezy conditions will also be common along the Lower CO.
- Bulk of the precipitation with this round is along the 84/86 corridor and south into the higher elevations.
- A Winter Weather Advisory will go into effect Monday evening for areas north of I-40, with expected minor impacts to roadways and bridges.
2" QPF range as the most likely, with a few outliers on both the high and low ends.
High pressure will slide southeast today into eastern SD by 00z.
- Freezing fog will result in some icy roads this morning across the Golden Triangle.
In the Flathead Valley, extending northwards, the soundings show the cloud layer thickening enough that there could be concern that fine snow crystals or even freezing drizzle could start to fall.
- A weather system will pass to the north tonight into Monday dropping temperatures into the normal range and bringing breezy conditions to the Lower Colorado River Valley, but dry conditions and mostly clear skies will continue to prevail. This is the first of a couple short wave troughs that will influence the Desert Southwest this week and will be to the east of the Four Corners region by Monday afternoon. As this first trough passes some breezy conditions will also be common along the Lower CO.
Currently, northwest flow aloft with an embedded S/WV trough propagating southeast across the Northern Plains. Low level clouds and scattered flurries persist, along with some light snow downstream of Lake Sakakawea where some lake enhancement is occurring thanks to the low level cold northwest flow over the warmer lake waters.
There is still time for a slight shift in location, but as of right now, the highest probabilities for the highest snow totals appear to be along and north of I-70. 0 inches of snow along and north of I-70, while the LREF Grand Ensemble has the highest band centered over I-70.
A weak cold front will move across northern Arizona this afternoon into tonight. Gusty winds and cooler temperatures are in store for most, with chances for rain and snow showers limited to the Four Corners region.

Issued by National Weather Service Cleveland OH 545 AM EST Sun Nov 30 2025 A low pressure system moves through the Great Lakes through this morning bringing a mix of rain and snow to the Ohio Valley.
Fog may have significantly decreased, but the low stratus layer with light snow/mist will be the main highlights for this mixture of flight categories (MVFR conditions or lower) for most sites except KDLS/KYKM/KPSC being VFR. The low stratus layer may last through this late morning/early afternoon for KPDT, KRDM, KBDN, and KALW, which should begin dissipating by then. Dry conditions are then anticipated into Monday afternoon as upper-level ridging noses into the Pacific Northwest.
