- Periods of Light Snow This Week
Typical winter weather into the weekend with no big storms but a
few clippers in fast northwest flow that will bring light snow.
THe first one comes in this afternoon with some lake enhancement
to the light synoptic snows and a general 1 to 2 inches by the
time the snow tapers off after midnight.
Snow will flare up again as the next shortwave trough follows
quickly for Wednesday. Expect another 1 to 2 inches by Thursday
morning before the trough axis moves east and heights rise. Light
lake effect snow showers are possible on Friday as weak shortwave
troughing occurs, but additional accumulations are not expected.

Lake effect snow continues to impact west michigan though
visibility reductions have lessened over the past few hours. This
trend is expected to continue for at least the first half of the
TAF period. Exception to this is KMKG where persistent snow will
bring IFR conditions through much, if not all of the taf period.
Expectation is still for a more widespread light snow and
reduction in visibility once again Tuesday afternoon and evening.
