FXUS63 KGRR 030459 AFDGRR Area Forecast Discussion National Weather Service Grand Rapids MI 1159 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 /06Z TAFS THROUGH 06Z WEDNESDAY/... Issued at 1159 PM EST Mon Feb 2 2026 Light snow continues but has diminished in intensity and is not obscuring visibility much. MVFR ceilings are likely to continue through at least the early morning hours. A modest increase in snow intensity is possible over the next several hours till daybreak as a trough swings through. Some scattering to VFR is possible during part of the daytime, more so in Central Michigan, but MVFR stratocumulus may redevelop again with daytime mixing. && .GRR WATCHES/WARNINGS/ADVISORIES...
