ALL TIMES ARE IN EASTERN STANDARD TIME
 
COOL TEMPS AND BLUE SKIES PREVAIL FOLLOWING
YESTERDAY'S FRONT...0.02 INCHES OF NEW RAIN ADDED
LAST EVENING.
 
Following the recent bout of humid conditions, this morning's
low of 56F was a significant change after the previous day's
overnight low of just 70F. Dew points today have largely
been held in the upper 40s today after yesterday's run in the
lower 70s.
 
A brief shower of 0.02 inches of rain last evening bumps up
yesterday's storm total of 0.29 inches, briefly stalling
our long-term drought-like conditions. Forecasts for dry
weather to finish the month will likely push the precipitation
deficit to over 2 inches.
