A light dusting of snow at most, though isolated bands of snow could produce locally higher amounts in Vilas County. - Gusty northwest winds diminish Friday afternoon. - Near normal temperatures on Friday and Saturday, then above normal temperatures return into next week. && .DISCUSSION... Issued at 949 PM CST Thu Nov 5 2026 Chilly with scattered snow showers to start as cyclonic N-NE flow across Lake Superior (delta t/s up to 16c) in wake of departing low is supporting lake effect snow showers into far northern WI. HRRR still showing embedded more organized bands drifting across Vilas County tonight, so though most accumulations will be limited to a dusting, a few spots could see up to 0.5 inch of snow. Otherwise, a few sprinkles and flurries could occur into Friday morning elsewhere. Showers late tonight into Friday morning along Lake Michigan may get a boost as winds veer more NE and edge of system to east backs in. Surface temps will be warm enough to keep ptype mainly rain, but some light snow could mix in for a time on Friday morning. Later Friday, increasing subsidence and lowering inversions will spell end to most lake effect over the north and showers along Lake Michigan will also come to an end. Soundings and RRFS cloud projections point to scattered to broken cu persisting well into the afternoon. Suppose there could be a sprinkle or flurry over the north from these clouds. Skies then clear out on Friday night as high pressure moves across. Gusty winds from earlier today will slowly diminish into Friday afternoon. Winds could still be gusty over eastern WI into Friday morning though as the pressure gradient only slowly relaxes. Saturday into next week...High pressure will bring dry weather over the state into early next week, with another warming trend beginning Sunday. Peak of warmth is Monday with a 40-60% of exceeding 60 degrees south of highway 29. Average highs are in the mid to upper 40s. Tranquil conditions will last until the middle of next week. There are differences in strength of the upper trough forecast to drop across the region by that time, but ensemble blend (LREF versus the NBM) indicates some chances of showers Tuesday night into later next week. It also could turn cool enough again for light snow to return over the north. In general though the pattern looks to remain warm and dry into the middle of the month. && .AVIATION...for 06Z TAF Issuance Issued at 1129 PM CST Thu Nov 5 2026 MVFR to low-end VFR CIGS will prevail through the TAF period as low pressure slowly exits to the lower Great Lakes and high pressure builds in from the upper Mississippi Valley. Colder air flowing across Lake Superior and upslope lifting will lead to lake effect snow showers over far northern WI overnight. Elsewhere, a few light rain showers, sprinkles will occur at times into Friday morning. Any clear skies should cloud in Friday morning with diurnally driven cumulus clouds expected to develop. These clouds should then dissipate with the loss of daytime heating, allowing for mostly clear skies Friday evening. North winds around 10 kts will diminish later on Friday. Winds may gust over 20 kts for a few hours early Friday morning in eastern WI. Light winds are then expected Friday afternoon into Friday evening. && .GRB WATCHES/WARNINGS/ADVISORIES...
