- Light Snow with chance of Freezing Precipitation Tonight

 Bottom line up front: Have held off on any headlines for now,
however there is the potential tonight into early Tuesday morning
for Freezing Rain/Drizzle through the northern two rows of
counties, especially along US 10 corridor and in and around Big
Rapids.

 A warm frontal pattern continues to approach from the west.
Current radar shows very light precipitation moving over the
region with most dissipating over the Lake.

 As the warm front approaches from the west, snow showers should
over spread the region this afternoon and evening. As the front
lifts out there will be a chance for some warmer air through the
mid levels with surface temps still at or below freezing.
Soundings at RQB from 06Z to 12Z Tuesday show a weak warm nose,
along with an unsaturated DGZ. Given that, there is the potential
of Freezing rain/Drizzle tonight into early Tuesday morning.

Temperatures remain marginal so have held off on any headlines.
However, will have to keep an eye out and we may issue and
advisory for this later today. The main areas of concern would be
in and around Big Rapids, Reed City, Baldwin down to White Cloud
region.

- Warm Weather Ahead

 No major changes to the forecast, Warm air will continue to
advect through the region this week, with temperatures increasing
through the week and peaking around Christmas. Rain is expected
Christmas night followed by a pattern shift bookmarked by a cold
front this upcoming weekend.

.AVIATION /12Z TAFS THROUGH 12Z TUESDAY/...
Issued at 744 AM EST Mon Dec 22 2025

VFR conditions will continue through the morning. A frontal
boundary is moving in from the west and the air continues to dry
most if not all precipitation moving across the Lake. There
remains a chance for snow showers which at times could bring MVFR
cigs and vsbys this afternoon and evening. The other aviation
concern will be LLWS from a LLJ this afternoon which could affect
all TAF sites.
 MVFR are likely overnight after frontal passage. Expect all TAF
sites to be affected with IFR possible at MKG.
