ALL TIMES ARE IN EASTERN STANDARD TIME
SUNRISE: 0505E

WARMER THAN NORMAL TEMPERATURES WITH OVERCAST SKIES
THIS AFTERNOON….
Today we observed 15 miles of visibility due to a thin
fog in the distance. Wind is currently around 5 mph with
a max gust around 15 mph. The wind has a northerly component
and definitely makes conditions cooler than initially
projected.
Skies are overcast with a thick layer of stratus clouds. A
very light drizzle was observed around 10 A.M. This
eventuality only left a trace (at best).
Temperatures today are cooler than normal so far.
The high so far today is 50F, which is 6 degrees below the
normal maximum of 56F. The low since midnight is 44F, which
is 7 degrees above the normal minimum of 37F.
