The pic. on the left is sunset from the Muskegon GLERL camera at the channel (from NOAA Coastwatch). The afternoon high temperature on the beach there Thursday was 57.6° for a sunny day in the 2nd week of August – amazing. On the right we have the overnight update from the Storm Prediction Center for Saturday PM/Night. There is a small Slight Risk Area over Missouri and a “See Text for West Michigan. SPC says: ” ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED DURING THE AFTERNOON/EVENING. WEAK INSTABILITY AND POOR LAPSE RATES WILL LIMIT THUNDERSTORM INTENSITY…BUT 0-6 KM SHEAR NEAR 30-35 KT AND FAST STORM MOTION COULD RESULT IN SOME GUSTY WINDS. COOL TEMPERATURES ALOFT /500 MB/ NEAR -10 C MAY ALSO ALLOW FOR SOME SMALL HAIL IN STRONGER STORMS.”
The overnight NAM (car.) has 0.08″ of rain for G.R. Sat. PM/Night – it hangs the front up and gives G.R. another 0.28″ Sun. PM/Night. The GFS-plot gives G.R. 0.03″ Sat. evening and another 1/2″ from Sunday midday into Sunday night. The European gives G.R. 0.12″ Sat. Night and that’s it. The models continue to trend downward for high temps. for early next week.
