Severe Threat Monday PM

spc  Click on the graphic to enlarge.  We are in the General Thunderstorm Outlook (green color on the map) and we have a “See Text” right over us.  Here’s what SPC says:  “AN UPPER-LEVEL TROUGH WILL MOVE ESEWD ACROSS THE WRN GREAT LAKES REGION MONDAY. AT THE SFC…A COLD FRONT IS FORECAST TO MOVE SWD ACROSS WI AND LOWER MI MONDAY AFTERNOON. SOUTH OF THE BOUNDARY…SFC DEWPOINTS SHOULD BE IN THE 50S F WITH MODERATE DESTABILIZATION TAKING PLACE. THIS COMBINED WITH 45 TO 55 KT OF DEEP LAYER SHEAR SHOULD BE ENOUGH FOR A SEVERE THREAT WITH CELLS THAT INITIATE ALONG THE FRONT. HAIL AND STRONG WIND GUSTS WILL BE POSSIBLE WITH THE STRONGER CORES. HOWEVER…THE RELATIVELY DRY BOUNDARY LAYER SHOULD KEEP ANY SEVERE THREAT MARGINAL.”    The wind should be from the WSW off the lake tomorrow, so lakeshore areas will be cooler (Sunday, the high temperature was 80 in G.R., 74 at the Muskegon Airport and 63 on the beach at Muskegon) and the air will be more stable, so I think there may be a better chance of a shower/t-storm in the PM/Evening to the northeast and east of G.R.

      That would be extremely boring, got to have seasons, you can always move to Florida where there are no seasons.
