THUNDERSTORMS….

just hung there for the rest of the day. Despite temperatures
in the 70’s, the air had a good amount of water in it to make
the weather slightly uncomfortable.
Visibility was 40 miles on average, increasing from 20 miles
of visibility this morning due to fog.
This was after yesterday’s thunderstorms, which left 0.71 inches
in our rain gauge.

an annual deficit of 10.83 inches!
The high so far today is 78F, which is a degree below the normal
