DISCUSSION
BREEZY EAST WINDS ARE ANTICIPATED THROUGH MUCH OF THE DAY TODAY WITH

THE PERIOD, THE EXPECTATION IS FOR A QUICK UPTICK THROUGH THE REST
OF THE MORNING. DRY CONDITIONS WILL ACCOMPANY THESE WINDS, WITH
AFTERNOON HUMIDITY DROPPING INTO THE 30S, BUT WOULD NOT BE
SURPRISED IF THESE VALUES SNEAK INTO THE 20S AS WELL. HUMIDITY
INCREASES OVERNIGHT AND INTO WEDNESDAY, WITH A FEW SHOWER CHANCES
POSSIBLE LATE TONIGHT, BUT ESPECIALLY ON WEDNESDAY. COMBINATION
