DISCUSSION

Issued at 1200 AM CST Fri Nov 6 2026

Today - Saturday: Cooler with More Sun

Skies are clearing across the region as upper level ridging builds from the west. A northerly fetch from Lake Superior will usher periods of clouds southward through the day in conjunction with afternoon cumulus development; however, look for far more sun than we've seen compared to the last five days. With continued cold air advection, highs today (mid to upper 40s) will actually hover a few degrees below average for this time of year. Surface high pressure builds southeastward throughout the day and will be overhead tonight. Lows should fall to the lowest values of the fall season thus far with many locales falling into the 20s and favored bog/sandy soil regions in western Wisconsin falling into the teens.

Sunday into Next Week: Warmer and Continued Dry

With heights aloft building through Monday, highs will return to solidly above normal, rising to around 60 for Monday (70-90% chance along and south of I-94 per 06.01z NBM). The arrival of a pair of upper troughs, the first Monday night and the second Wednesday, will moderate temperatures somewhat, with highs in the 50s favored next Tuesday and Wednesday, still a bit above normal.

As for precipitation, available moisture with each of the aforementioned waves is lacking, particularly with Monday night's trough. However, 05.12z GFS does suggest some mid-level saturation following the frontal passage associated with the wave next Wednesday, which could lead to a light post-frontal shower or two if this feature moves through during the daytime hours. Post-frontal showers are a low possiblity for now (<10%), mainly appearing in the operational GFS and a few ECENS members. Either way, impacts are not expected.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1122 AM CST Fri Nov 6 2026

VFR conditions are forecast for the first half of this TAF cycle. A light north wind around 5-10 kts is expected during the daytime hours before becoming southerly to southwesterly overnight and remaining under 10 kts. Occasional and brief MVFR ceilings are possible during the day as cumulus develops over the terminals. The next potential for MVFR ceilings occurs late in this TAF issuance as potential low clouds develop and move east across the area. Confidence in MVFR ceilings is high enough (55-70%) to mention at KRST and may get to KLSE, but confidence is much lesser at that site right now.
