AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1245 PM EST Fri Jan 16 2026

Radar shows an area of 25-35 dbz echos near MKG/GRR. This corresponds to 1/2 mile visibility and perhaps brief periods of 1/4 mile visibility. This area of snow will persist for a couple of hours before moving northeast. The southern terminals will see the lower visibility band move east with fairly rapid improvement around 20z.

Another surge of arctic air will move over the lake late tonight and produce another round of lake effect snow and lower visibilities Saturday morning, mostly at GRR/MKG, but perhaps clipping AZO...although that is less certain.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 635 PM EST Fri Jan 16 2026

Radar shows an uptick in echo activity between I-96 and I-94. A deep upper trough is over the region and minor short waves continue to pivot and rotate through the trough. The upper trough won't move through the state until Saturday night. As such we'll continue to see light snow at times. A mix of IFR/MVFR expected through the period.
