DAILY DISCUSSION AND CLIMATE SUMMARY
THURSDAY, FEBRUARY 18, 2016
ALL TIMES ARE IN EASTERN STANDARD TIME

CLEAR AND COOLER CONDITIONS PREVAIL WEDNESDAY AND THURSDAY

Following a roller coaster start to the week, temperatures and
conditions began to moderate under an area of high pressure moving
into the region. Temperatures had remained warmer than normal,
with temperatures dipping down to 25F this morning, some 5 degrees
warmer than today’s normal daily low.

A cold front that moved through overnight brought in drier, slightly
cooler air. Skies were mostly clear this morning, and by today’s
1:00 PM EST observation skies were almost completely clear of clouds
with a visibility of 75 miles in all directions.
