The top pic. shows low temperatures Saturday AM. I had 30° at my house in Alpine Township. Other flow temps: 28° Watervliet and Grand Junction, 25° at Manistee and 21° in Kenton and Baraga Plains in the U.P.
The cool pattern continues with a 5-Day stretch of temperatures in the low-mid 30s with at least scattered frost.
On a cold, calm, clear night, cold air sinks to the lowest spots – so valleys will be cooler than higher hilltops. That’s why fruit farmers employ orchard fans to stir the air. Occasional you’ll see a helicopter flying over orchards on a cold, spring night to stir up the air.
Snow fell across parts of Upper Michigan and N. Lower Michigan. Above you can see that Herman MI, (west of Marquette in the U.P.) had 2″ of snow on the ground Friday morning. Here’s video of snow falling at Gaylord in N. Lower Michigan.
One benefit for Michigan in this cool pattern is that severe weather and tornadoes stay south in the warmer, more humid air. This is the Severe Weather Outlook Map for Sunday, May 9. There is a Slight Risk from E. Texas to SE Missouri and a Marginal Risk up to S. Indiana and W. Kentucky.
Our only chance of rain over the next 5 days will come early Sunday. It will rain across Illinois, Indiana and Ohio. The north edge of the rain will come up into S. Lower Michigan with the best chance of rain along and south of I-94.
This is the U.S. Drought Monitor. Drought is ranked from 0 (abnormally dry) to D4 (exceptional drought). Much of Lower Michigan and E. Upper Michigan are classified D1, which is moderate drought. Much of the Corn Belt (from E. Nebraska to W. Pennsylvania) has ample moisture as we start planting.
Grand Rapids has had 7.16″ of precipitation this year. The average precipitation thru 5/8 is 12.08″, so we are 4.92″ below average.
