THURSDAY, AUGUST 25, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0502E

LOWER VISIBILITY WITH ALMOST NO WIND IN THE AFTERNOON….

Today started off clear with a good amount of cumulus clouds
moving in around noontime. Visibility was 45 miles on average,
and wind was roughly 2 mph since the 10 A.M. observation.

Today was still on the humid side with dew points in the upper
60’s.

Most of the Boston area is still in an extreme drought, while
the south shore and Cape are in a severe drought given the
rainfall that occurred a couple days ago.

The summit is at a monthly rain deficit of 1.79 inches, and
an annual deficit of 11.30 inches!

The high so far today is 88F, which is 9 degrees above the normal
