681 FXUS63 KGRR 022338 AFDGRR Area Forecast Discussion National Weather Service Grand Rapids MI 638 PM EST Mon Feb 2 2026 .KEY MESSAGES... - Lingering Light Snow This Evening - Snow Thursday night into Friday - Colder with Lake Effect next Weekend && .DISCUSSION... Issued at 306 PM EST Mon Feb 2 2026 -Lingering Light Snow This Evening The Winter Weather Advisory continues for areas of freezing drizzle and icy roads from Muskegon County to Gratiot County and south. As the front moves through over the next two hours any freezing drizzle should transition to snow. Any additional ice accumulations would be a light glaze with snow amounts less than a half inch. Areas to the north have only observed snow, therefore have cancelled the Advisory in these areas. - Snow Thursday night into Friday No changes from the previous forecast as probabilities continue to fall for 2 inches or more of snow now at 20 percent or less across much of the area. Southwest flow ahead of the trough could bring some light lake effect snow showers earlier in the day Thursday otherwise most of the snow is expected to occur Thursday night into Friday. Most of the synoptic support remains north of the area resulting in the lower snowfall amounts. Either way this nuisance snow for the Friday morning commute could bring some brief travel impacts. Friday temperatures are forecast to rise above freezing which would be the first time since mid January. - Colder with Lake Effect next Weekend Behind the front Friday colder air will advect into the region bringing with it highs in the teens to low 20s and lows near zero over the weekend. Mean 850mb temperatures Saturday morning around -16C will result in lake surface temperature differences around -18C which will be supportive of lake effect showers. 850mb temperatures will slowly warm during the weekend reducing that temperature difference with lake effect gradually tapering off Sunday. && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/... Issued at 634 PM EST Mon Feb 2 2026 Radar shows snow still falling across the region. Models are not handling this well at all. Instability over the lake remains sufficient for lake effect snow production through the night. Additionally, a short wave will move south over the terminals after midnight and we`re likely to see an uptick in radar echos. The DGZ remains saturated and the same height overnight. Thus, we kept light snow falling at the terminals through 12z. Much of the lift is situated below the DGZ and so the snow should remain light. However, MVFR with pockets of IFR remain the most likely scenario overnight. && .GRR WATCHES/WARNINGS/ADVISORIES...
