MILDER AGAIN WITH DECENT VISIBILITY ATOP GREAT BLUE HILL….

Today was cooler in the morning hours, but reached the upper
60’s by the 1 P.M. observation. Visibility was 60 miles, and
skies were clear for the most part. Wind was southwesterly
with speeds of 10 mph on average, gusting to 15 mph every

holding in the low 40’s. The drought monitor is
showing significant improvement, with many areas
south and west of Boston being in the “abnormally
dry” category. Northern Massachusetts and the Boston
Area are the only ones with a moderate drought.

We are looking at an inch surplus of rainfall to the
