Severe Weather Threat

Central Great Lakes sector loop
Here’s local and regional radar – these will update automatically.  Up top is the Severe Weather Outlook Area for today (Fri.).  Michigan is in the light green General Thunderstorm Outlook.  We do have a chance of a t-shower, mainly mid-late PM, but could occur at any time (early in the day threat greatest along the Indiana border.  The activity will be widely scattered and some of you will get thru the day without rain.

  This is the Severe Weather Outlook Area for Saturday PM/Night.  Southern Lower Michigan has been upgraded to a Slight Risk (yellow) with a Marginal Risk to the north.  There is certainly the chance of severe weather Saturday PM/Night, with strong wind being the primary threat and hail a secondary threat.

  Thursday was another big day for severe weather…no tornadoes, but lots of reports of wind damage and hail.  SPC nailed the area of Kansas in the Moderate Risk.  Severe reports from the U.P.:  Gust to 59 mph at Grand Marais and 54 mph at Houghton.  Golfball-sized hail fell at the golf course in Munising.  Hail the size of ping-pong balls fell at the town of Christmas.  1″ diameter hail was reported at Steuben, with nickel-sized hail at Shingleton.  Both Au Train and Lake Linden had marble-sized hail.

Also:  Cool time-lapse of clouds at Mobile AL.  A Record 4,252 days since a Category 3+ hurricane made USA landfall.  Circumhorizontal arc.  From June 1 to 15, Key West received 5.41” of rain. The month’s normal rainfall is 4.11”:  I’d have quit and gone inside.  Seattle had 1.05″ of rain Thursday, a daily record.
