766 FXUS63 KGRB 302111 AFDGRB Area Forecast Discussion National Weather Service Green Bay WI 311 PM CST Sun Nov 30 2025 Forecast discussion for routine afternoon forecast issuance .KEY MESSAGES... - Travel conditions will continue to improve this evening, however light lake effect snow in far north-central WI will continue to produce slippery spots on roads. - Much colder air arrives this week. Wind chills will likely fall to the single digits below zero Monday morning. Even colder air arrives Wednesday night. - Off and on chances for light snow this week, but overall impacts are minimal. && .DISCUSSION... Issued at 306 PM CST Sun Nov 30 2025 As of 20Z, there were some lingering light snow or flurries across far eastern WI/Door County, along with lake effect snow in far north- central WI. Otherwise, snow had ended. Blowing/drifting concerns were also minimal as the snow has settled and winds have started to decrease a bit. Additional snowfall accumulations of a few tenths are possible late this afternoon and early evening across mainly Vilas County. Cold Temperatures...High pressure builds in from the west tonight, and while the center of the high will pass south of the area, the combination of light winds, partial clearing, and fresh snow will allow temperatures to drop into the single digits, with some locations in north-central WI likely getting a couple degrees below zero. While winds Monday morning will be light, any bit of wind will create a wind chill around 0 to 10 below. Temperatures remain below normal through the week, with a secondary push of cold air behind an Arctic front Wednesday night, as lows drop in the single digits below zero for most. Wind chills Thursday morning are forecast to range from 10 to 20 below. Precip...There are minor snow chances throughout the forecast, but overall impacts from each event looks low. The next chance for snow is Monday afternoon and evening, primarily across central and east-central WI (or south of Hwy 29), as this is the far northern periphery of a system located much farther south. A dusting to a couple tenths is possible. Dry weather is expected Tuesday, followed by chances (30-60%) for light snow on Wednesday in association with the Arctic front. Moisture is rather limited, with forecast snow amounts around 1 inch or less. There are chances for snow again Friday and into the weekend, but specifics are hazy this far out. Sunday currently looks like the best opportunity to pick up a couple inches of snow for some. && .AVIATION...for 18Z TAF Issuance Issued at 1213 PM CST Sun Nov 30 2025 Overall, trends are improving as the system departs. Snow has mostly come to an end, but lake effect snow will continue in north-central through early to mid evening. Lake effect snow will reach the KRHI TAF site at times, bringing temporary visibility and ceiling drops to IFR or LIFR. Elsewhere, a mix of VFR and MVFR conditions exist with SCT-BKN clouds around 3kft. Sky conditions will improve area-wide this evening as low clouds depart and partial clearing occurs. Northwest winds remain gusty, with gusts to 20-30 kts expected through late afternoon. While isolated blowing/drifting remains possible from the winds, this has largely ended as the snow settles. Winds will subside this evening and gradually back to the W and SW tonight into Monday. && .GRB WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION.....KLJ AVIATION.......KLJ
