Most of Michigan under severe storm threat; Isolated tornado possible Up North

Storms to arrive early Thursday morning in Metro Detroit

The severe storm threat has expanded, now including nearly every square mile of the state.

Most of our viewing area is under a Marginal Risk, which is the lowest on the five category scale.

The strongest storms (and possibly a tornado) will be most likely in the U.P. and northern lower Michigan tonight. By the time storms arrive here, they should be weakening.

A wind gust topping 50 or 60 mph cannot be ruled out. Temperatures snuck into the 80s in multiple spots in our West and South Zone.

Warm air will continue to move in during the night keeping temperatures in the 70s until a cold front arrives with those storms between 3 a.m.  and 5 a.m.

Those balmy numbers will be our technical high for Thursday. Temperatures will fall into the 60s during the morning commute and stay there until the evening.

Any rain should be gone by 7AM, leaving us mostly sunny for the majority of tomorrow.

Friday and weekend outlook

Friday brings a small chance at a light shower, but with cooler than normal temperatures. The day starts in the upper 30s to low 40s. Then daytime highs end up on either side of 60.

Rain will be likely Saturday and possible Sunday. Temperatures will be unseasonably warm both days and may touch 80 on Saturday.

We have very low confidence in next week’s forecast as of now. Temperatures should stay well above normal, but rain timing is suspect.

This is a very active, complicated forecast with wild swings in just about every measurable weather parameter. So highs and lows may not (and likely won’t) occur in the normal hours of the day.
