Weather forecast: Quieter day across SE Michigan

By Paul Gross - Meteorologist

If you read my weather article Thursday, you may recall my extensive discussion about the wind shear that would exist during the afternoon.

Thursday's storms

If late-afternoon / evening thunderstorms developed, that wind shear would cause some of those storms to rotate, yielding a tornado potential. However, getting those storms to pop was dependent upon us getting enough late-afternoon sunshine. There was a razor-thin margin of error, and now you can see why: While most of us did not receive a late-day storm, a line of showers did develop across our North Zone -- and it appears that one shower dropped a tornado in Tuscola and Sanilac Counties.

Most remarkable is that there was no lightning with the cell!  This shows you how critically important that wind shear was: A heavy shower developed, it wasn’t a storm, and yet there was still an impressive enough wind field to generate a tornado. The National Weather Service will send out a storm survey team today to study the damage path and confirm if it was indeed a tornado (although video I’ve seen suggests that it was), and determine its statistics.

Friday forecast

Today will be much quieter.  Even though we could start with some sunshine, skies will become mostly cloudy.  Cooler air filtering in behind last night’s cold front, combined with the clouds, will hold temperatures in the mid to upper 70s (25-26 degrees Celsius).  West-southwest wind at 10-20 mph.

Today’s sunrise is at 6:44 a.m., and today’s sunset is at 8:29 p.m.

Skies will clear early tonight, followed by more clouds moving in later.  Lows in the low 60s (17 degrees Celsius).

Weekend forecast

Saturday will be partly to mostly cloudy, with scattered showers and thunderstorms possible as an upper level disturbance crosses the Great Lakes.  Highs in the mid to upper 70s degrees (26-27 degrees Celsius).  It had better not rain at the Farmington Farmers Market Saturday morning, because I’ll be there to ring the opening bell and participate in some other activities, including the corn roast…you can get a roasted ear of fresh Michigan corn for only $1 and, best of all, it’s a fundraiser to help some local charities!  See you there in beautiful downtown Farmington.  And it had better not rain on the meteorologist.

Becoming mostly clear Saturday night, with lows in the low to mid 60s (16-17 degrees Celsius).

Mostly sunny on Sunday -- a splendid Pure Michigan summer weekend day, with highs in the mid 80s (29 degrees Celsius).

Eclipse day forecast

Mostly sunny skies continue into Monday, which means that we’ll be able to see the partial solar eclipse!  Peak eclipse time for us is 2:30 p.m.  I’ve put lots of stories and information on Detroit’s official eclipse webpage on -- check it out!  Highs warming into the upper 80s (31 degrees Celsius).  Remember:  DO NOT LOOK AT THE SUN WITHOUT SPECIAL ECLIPSE GLASSES. 

You wouldn’t look at the sun on a normal sunny day, and the sun on Monday will be just as intense to your unprotected eyes.  Every time there’s a solar eclipse, I hear about somebody somewhere suffering permanent eye damage due to trying to look at the sun without eclipse glasses.  Please don’t become that sad statistic.

The next cold front looks to approach Tuesday afternoon with our next chance for thunderstorms.  Hopefully it’ll hold off until after the golfing is done at Frank Beckman’s March of Dimes Celebrity Golf Classic at Indianwood.  Once again, it had better not rain on the meteorologist.
