HIGH PRESSURE OVER NEW ENGLAND BRINGS US SUNNY SKIES AND LIGHT WIND

Ongoing high pressure gave us another day of mostly sunny skies with 
visibility reaching 80 miles. Yesterday's max temperature was 89F, but 
today's was a little cooler with the max temperature reaching 81F by 
the 1:00PM EST observation. Dew points in the low 50s and a light wind 
has made today very pleasant. Dry conditions have pushed our monthly 
precipitation deficit to just over 2 in. as an extreme drought continues.
