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 /12Z TAFS THROUGH 12Z SUNDAY/...
