079 FXUS63 KGRR 131057 AFDGRR Area Forecast Discussion National Weather Service Grand Rapids MI 557 AM EST Fri Feb 13 2026 .KEY MESSAGES... - Quiet Weather into Next Week then Potential Storminess && .DISCUSSION... Issued at 247 AM EST Fri Feb 13 2026 - Quiet Weather into Next Week then Potential Storminess The quiet weather pattern continues through the weekend as a southern stream low tracks south of Lower Michigan. The northern stream remains separate with clipper lows passing north of the Great Lakes today and again Monday. Temperatures moderate as upper heights rise over the weekend. Then we have to watch for a "baroclinic battle zone" setting up across the Great Lakes region for next week. The next chance for precipitation is late Tuesday into Wednesday as warm advection increases with enough moisture to bring a chance of rain or mixed precip with the highest chances across the northern forecast area. We will have to watch the placement of a cold anticyclone across the Hudson Bay region during this time with the potential for freezing rain or frozen precip by Wednesday across the central and 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 the rain/mixed precipitation which should change to snow by late Thursday or Friday as cold air filters in on the back side of the low. && .AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
