Much of Wisconsin and Lower Michigan are in the Slight Risk Area for severe storms on Monday from the Storm Prediction Center. It looks like north of a line from Muskegon-Saginaw. They say: “A LINEAR MESOSCALE COMPLEX APPEARS LIKELY TO BE ONGOING AT THE START OF THE PERIOD ACROSS ERN WI AND LAKE MICHIGAN WITH THE CONVECTIVE COMPLEX MOVING EWD INTO LOWER MI THIS MORNING. IN THE WAKE OF THE MCS…MODERATE INSTABILITY IS FORECAST TO DEVELOP ACROSS THE UPPER MS VALLEY AS A 75 TO 90 KT MID-LEVEL JET APPROACHES THE REGION FROM THE WEST. THE MODELS DEVELOP SCATTERED THUNDERSTORMS THIS AFTERNOON ACROSS THE WARM SECTOR SOUTH OF THE MID-LEVEL JET AXIS FROM NRN IA AND SRN MN EXTENDING ENEWD ACROSS WI INTO NRN MI.” 5:45 AM update – A large area of showers and t-storms continues to move across Wisconsin, with some showers and storms over Lake Michigan. Very little severe weather has been reported in Wisconsin with these storms. Check out Grand Rapids NWS radar, Milwaukee radar and Minneapolis radar (cool pic. here and here). There was also flooding. Here’s Minnesota Storm Reports… Gust to 76 mph at Appleton, MN and 77 mph at Cosmos, MN…72 mph at Lester Prairie, MN. The main threat today in the Risk Area will be wind. What you can do now, ahead of any storms is pick up the yard/outside to make sure nothing (like your garbage bin) will be dancing down the street if you get some wind, don’t park under trees, keep your garage door closed (esp. if it faces west) and keep coming back to the blog for the latest (click the links). NAM Model gives G.R. 0.03″ of rain from mid morning to midday. The GFS has .07″ and the European 0.03″. The models give us another round of showers/t-storms later Weds. night/Thurs morning with the next cool front and then another round of storms Saturday PM/Night. The European gives G.R. a 2 PM temperature of 92 Tues. and Weds. Usually, the high temperature is about 4 degres higher than the 2 PM temperature, so we have a couple of back-to-back scorchers for Tues./Weds. I’ll update when I can and we’ll have some great comments from people who are knowledgeable, even if I’m doing TV and can’t update. Click here for the current SPC outlooks and discussion.

I have 2 cats. At the first grumble of thunder, cat 1 runs to the basement and hides under the sofa. Cat 2 is asleep on the porch next to me amid fairly intense cloud-ground lightning and VERY loud thunder.
