DETROIT – Temperatures in the 40s are still on the horizon for the next two days, but that won’t keep the snow away from our weekend.

Mild midweek

With normal highs still in the low 30s, getting temperatures above 40 degrees can seem like quite a vacation. It’ll happen for most of us Wednesday, and for everyone Thursday.

Those days will be only the second and third times this year the mercury has reached 40. Don’t expect much sunshine, either.

This “mild-up” will be the exclusive work of southwest winds, ushering in a warmer airmass. Beyond that, it gets wintry in a hurry.

Weekend snow

Temperatures drop Friday, winds pick up and rain starts to fall soon after midnight, keeping the morning wet.

That precipitation will transition to snow in the afternoon, leaving us with widely scattered, very sporadic snow showers Friday night through Saturday, although Saturday should be mainly dry.

On Sunday, a wave off of the main system will sweep through, turning up the volume of snow showers, especially in the afternoon and evening. Accumulation still looks minimal, with around 1 inch expected for the entire event.

Monday is now looking dry.

Winds will still be brisk Saturday and Sunday, so with daytime highs in the mid-30s, wind chills will be in the teens and low 20s for both weekend days.

Nearly normal

Beyond our active weekend, temperatures will flatline early next week. These familiar mid-30-degree highs will stick with us.

It does look like we might see some more frequent breaks in our Great Lakes permacloud, so stay tuned for brighter days!
