421 FXUS63 KGRR 140757 AFDGRR Area Forecast Discussion National Weather Service Grand Rapids MI 257 AM EST Sat Feb 14 2026 .KEY MESSAGES... - Quiet Weather into Tuesday then Potential Storminess && .DISCUSSION... Issued at 256 AM EST Sat Feb 14 2026 - Quiet Weather into Tuesday then Potential Storminess Quiet weather pattern continues through the weekend as a southern stream low tracks south of Lower Michigan. The northern stream remains separate with a clipper low passing north of Lower Michigan on Monday. Milder temperatures continue as the polar jet remains to the north until later next week. The next chance for precipitation is late Tuesday into Wednesday in an area of warm advection and isentropic ascent with enough moisture to bring a chance of rain or mixed precip with the highest chances across the northern forecast area. Thermal profiles of model forecast soundings show potential for freezing rain across the northern forecast areas, where there have been freezing rain episodes during previous periods of milder temperatures this winter. A second wave of low pressure late in the week could also bring rain/mixed precipitation which should change to snow by late Friday as cold air filters in on the back side of the low. && .AVIATION /06Z TAFS THROUGH 06Z SUNDAY/... Issued at 1138 PM EST Fri Feb 13 2026 The potential of some fog tonight is our main focus with the 06z forecasts. KMKG has already seen a few brief periods of MVFR fog over the last couple of hours. They will have the best chance of impactful fog, likely into IFR category. This is because they have the lightest winds there, and cross-over temperatures for fog are more likely to be met. The threat will taper off as you head to the SE, due to better winds holding up. Once the fog burns off in the morning hours, lots of VFR expected through the day. Winds will generally remain under 10 knots. It is looking like fog will be more likely everywhere right at the end of this forecast period with higher moisture and less wind expected. No concerns for the GRR forecast. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...None. MARINE...None. && $$ DISCUSSION...Ostuno AVIATION...NJJ
