DISCUSSION

Issued at 354 AM CST Sun Nov 30 2025

Latest surface analysis this morning shows low pressure entering the Chicagoland region of Illinois and continuing northeast. The western edge of that system (which brought us this snowfall), is seen well on nighttime microphysics. Stratus coupled with light snow is still working on clearing out of the eastern half of Minnesota and western Wisconsin. Snow should continue to taper off from west to east through this morning and all should be snow-free around noon if not sooner. Storm total snowfall amounts as of 12 AM for our climate sites were: NWS Twin Cities were 6.5 inches, MSP Int'l Airport at 3.9 inches, and EAU 4.0 inches. More measurements across the area should begin to filter in by mid- morning. As always, feel free to provide your snow total measurement via social media or emailing our office as its greatly appreciated!

Now that this low has passed, the "fun" part of this winter storm arrives, i.e. cold temperatures. Colder air is being channeled between the aforementioned low to our SE and building high pressure to the west. Across much of MN, breezy NNW'ly gusts are being reported to range between 20-25mph. These winds could create a few areas of blowing snow over the next couple of hours before decreasing this morning. Overcast skies should transition to partial sunshine by this afternoon. Forecast highs today will depend on your location. Areas across western MN and closer to the region of high pressure will see highs in the teens. Areas east of the St. Croix River Valley will reach reach the low 20s. Lows area wide tonight will be near 0 degrees.

Surface high pressure continues moving SE'ward into Iowa and reaching its peak strength ~1036mb Monday. Forecast high temperature distribution appears uniform near the 20 degree mark. Skies for most folks will be mostly cloudy although some sun might try and break through the clouds across southwestern MN. Lows Monday night will range in the single digits. By Tuesday, temperatures warm up slightly into lower 20s.

By Wednesday, upper-level troughing sinks southward over the Hudson Bay below in the mid-levels, a clipper system develops over Saskatchewan and heads ESE across the Int'l border. Forecast guidance currently favors a chance of snow showers during the daytime hours. As of now, snowfall accumulations look to be only minor featuring a trace up to a half-inch possible. Strongest chances for any snow to fall are up near Lake Superior which is outlined well by the latest NBM. Temperatures once again will be kicked down post-FROPA. Highs will return to the teens and lows nearing the double digits below zero for early Thursday morning.

AVIATION /12Z TAFS THROUGH 12Z MONDAY/

Issued at 642 AM CST Sun Nov 30 2025

Snowfall has shown significant signs of waning per KMPX radar over the past hour, and this trend will continue such that by about 14z, any and all snow is expected to cease. Ceilings will still dip down into MVFR range for much of the day before lifting and partially clearing out this evening through tonight. Another round of MVFR ceilings is possible after sunrise tomorrow. NW winds around 12G22kt at initialization will drop in speed to at-or-below 10kts by late morning and continue to drop to light/variable tonight through sunrise Monday morning.

KMSP...Snow is ending over MSP at initialization, with visibility already back to VFR levels. However, ceilings may dip down to MVFR by late morning and continue as such through the afternoon before partial clearing takes hold tonight. Another round of low ceilings looks likely late Monday morning but ceilings at MSP may remain just above MVFR thresholds.

/OUTLOOK FOR KMSP/ TUE...MVFR ceilings likely, chance IFR ceilings. Chance -SN overnight. Wind SW 5-10kts. WED...MVFR ceilings likely, chance -SN early. Wind NW 10-15kts. THU...VFR. Wind SW 5-10kts.
