- Lingering Light Snow and Flurries

850mb and water temperature delta T's remain in the upper teens, paired with deep enough moisture expect flurries and light snow showers to continue this afternoon before drier air moves in this evening. Gusty west to northwest winds will also become light overnight before shifting to the south Thursday. With the light winds, clear to partly cloudy skies, and 925 mb temperatures around -11 with a weak inversion expect low to drop into the upper single digits to mid teens.

Thursday a weak shortwave trough will swing through the region. Soundings show there could be enough moisture for some flurries and light snow. Little to no accumulation is expected.

- Warm Friday; Snow Possible Saturday

Warm air advection Thursday night into Friday will bring mild conditions with afternoon temperatures in the upper 40s to low 50s. We will have to watch a slight signal for drizzle as seen in both the NAM and GFS soundings Thursday night into Friday morning. Depending on surface temperatures there could be a brief period of freezing drizzle before temperatures warm and the low levels dry out.

A cold front will move through Friday night and may spark some showers toward the 127 corridor as the better moisture builds ahead of the front. Otherwise snow chances increase Saturday afternoon due to low to mid level frontogenesis that develops between high pressure from the northwest and a low pressure system to our southwest resulting in a tightening temperature gradient. NBM probabilities only show a 20 percent chances of 2 or more inches of snow with this system. 1 inch or more probabilities are in the 20 to 40 percent range peaking along the I-96 corridor. Overall not expecting high snowfall totals with this quick hitting event.

- Next Week: Cold Early, Then Warming

Southern Michigan could be on the northern edge of another light snow system Sunday night into Monday (20 to 30 percent). Temperatures Sunday will be in the 20s to around 30 and then warm each day reaching into the 40s by mid week. Southwest flow bringing moisture and lift with the warmer temperatures could cause a potential wintry mix (20 to 30 percent) Precipitation type will depend on the timing and temperature.

AVIATION /18Z TAFS THROUGH 18Z THURSDAY/

Issued at 1234 PM EST Wed Feb 25 2026

Local radar shows light lake effect snow showers falling over portions of central Lower. Conditions will be favorable for LES through the evening. However, we don't expect much more than flurries at MKG and perhaps GRR. MVFR cigs will continue through the afternoon at MKG/GRR/AZO and lift to VFR toward sunset. VFR expected overnight and Thursday morning.
