It usually doesn't get warmer behind a cold front, but it'll happen tomorrow across much of the area.
Granted, it was in the 70s across our southern counties (Genesee, Shiawassee, and Lapeer) on Tuesday and these places won't be a ton warmer tomorrow.
But highs were only in the 50s and 60s from the Tri-Cities northward on Tuesday, and these places will see highs ranging from the mid-70s to near 80° tomorrow!
Overnight, we'll be cloudy along a warm front with a few stray showers -- possibly a t'storm.
These clouds will keep our overnight lows from falling much below 58° or so, which is more typical of July than May!
After this warm start, the warm front will push through and a cold front will follow quickly behind it.
With clearing taking place behind these fronts and a lack of truly "cold" air behind it, the warm May sunshine (which is actually as strong as July sunshine) will warm our temperatures into the 70s north, and to near 80° in our southern counties.
Another cold front will come through mid-day on Thursday.
Even behind this front temperatures will only cool a few degrees, so I hope you get to enjoy the pleasant, sunny weather this week!
