Be Grateful for the Rain You Get

1630 UTC Day 1 Outlook0700 UTC Day 2 Outlook1630 UTC Day 3 Outlook These are the Severe Weather Outlook maps for today (Thu.), tomorrow ( Fri.) and the next day (Sat.).  SPC upgraded to a Slight Risk Area (in yellow) for SE Wisconsin and N. Illinois with the early PM update.  The Marginal Risk Area (dark green) sneaks into West Michigan west of a line from Benton Harbor to Traverse City.  SPC says:  ” Afternoon heating of the pre-frontal boundary layer will support airmass destabilization sufficient to support development of thunderstorms, with greatest coverage of storms expected from southeast Wisconsin southwestward along the boundary to eastern Iowa/northwest Illinois. Within this area, the strongest mid-level flow is also progged, on the southern fringe of the well-defined
upper circulation now moving east across the upper Mississippi Valley at this time per latest water vapor loop. With this zone of stronger flow aloft aiding in potential for organized storms and possibly some upscale/linear growth, risk for damaging winds appears sufficient to support upgrade to 15% wind/SLGT risk. Storms will spread east into the evening, weakening diurnally as they cross Lake Michigan and move into lower Michigan/Indiana.

Friday late AM water temps:  Reeds Lake 76, Ludington 71, Pentwater 70, Grand Haven 64, Holland 71, Saugatuck 68, S. Haven 72, S. Haven buoy 72.5.  Don’t know if you’ve noticed this…but Grand Haven seems to have the lowest water temp. most days.  Don’t know why that is.
