There are two Severe T-Storm Watches. We have one that covers most all of Lower Michigan (not Berrien or Cass Counties and another Severe T-Storm Watch until for Branch, St. Joseph and Hillsdale Counties in Michigan, for much of Eastern Indiana and for Western Ohio. The main threat is isolated damaging wind. A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT TO 1-INCH (not a high risk of hail). EXTREME TURBULENCE AND SURFACE WIND GUSTS TO as high as 70 mph. Individual storm movement southwest to northeast at 35 mph with the line(s) progressing from west to east across the area. Chance of rain – very high. Chance of severe (60 mph winds or 1″ hail) in any one spot – low. We’ve heated up near 80 deg. (pretty good instability). Dewpoints up into the low-mid 60s – so we have available moisture. Surface map shows marginal convergence. Not a lot of lightning so far, many areas just getting rain showers. Over 70 severe reports in the U.S. today.
Looks like a cool weekend…could be breezy, chilly and wet Sat. AM – No frost, wind should hold up Sun./Mon. mornings…but low 40s possible.
