- 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 /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1207 PM EST Fri Feb 13 2026

No aviation concerns over the next 12 hours as dry air and high pressure lead to SKC across West Michigan, with southwest winds to around 10 knots. Light and variable winds with clear skies will allow for favorable radiational cooling conditions and the potential for patchy fog. Have put in MIFG at GRR/MKG where the signal for fog is best and will evaluate whether restrictions are needed with the 00z package given the expected sporadic coverage of fog. We will also see VFR clouds sub 5kft develop across Central Lower Michigan and approach LAN. Any fog that does develop dissipates by mid morning Saturday. Winds increase to around 5 knots from the southeast Saturday.
