HUMID DAY WITH LIMITED VISIBILITY AFTER YESTERDAY’S
THUNDERSTORMS….

Today started off foggy with a dew point of 68F, and it
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.

The summit is still at a monthly rain deficit of 1.32 inches, and
an annual deficit of 10.83 inches!

The high so far today is 78F, which is a degree below the normal
maximum of 79F. The low since midnight is 67F, which is 6 degrees
above the normal minimum of 61F.
