This is a picture from the GLERL camera on the lighthouse at S. Haven (from NOAA Coastwatch). The anemometer at the lighthouse here recorded a peak wind of 64 mph as the storm came thru and that was right about the time this picture was taken. You can see the whitecaps and the rain moving in as you look north. The chance of rain today isn’t zero, but it’s only about 10%. Dewpoints will be significantly lower. So, after a rather damp start with a heavy dew and a few patches of fog, it should be a nice day with partly sunny skies and more comfortable humidities.

The overnight run of the European model gives G.R. dry weather until late Thursday night. It prints out 0.19″ for Friday, 0.55″ Saturday PM, 0.39″ Saturday night – we get a little break – then the model gives us another 0.50″ late Monday into Monday night. The GFSX model has these percentage predictions for measurable rain: 10% Thurs., 65%, Fri., 80%, 74% Sat., 65% Sun., 61% Mon., 56% Tues. Still no 90° for G.R. on the European run. Have a great day!
