BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY TUESDAY, MARCH 25, 2014 ALL TIMES ARE IN EASTERN STANDARD TIME UNSEASONABLE COLD AND CONTINUED DRYNESS LINGERS WITH CLOUDS ON THE INCREASE. A strong push of Arctic air arrived during the early morning hours yesterday, bringing with it chilly temperatures and gusty NW winds. With only a daily maximum of 32F, and a daily average of 23F, temperatures were 15 degrees below the 30-year average. With the approach of tomorrow’s major weather maker clouds have been on the increase with a thin overcast of cirrostratus dominating the sky since mid-morning. Although dew points have remained in the single digits above zero, they too have slowly been on the increase as moisture slowly moves into the region. By 1:00 PM EST light distant haze remained visible in all directions keeping visibility to 45 miles. Cumulus from the 10:00 AM EST observation had morphed and flattened into stratocumulus with cirrus fibratus and a thin veil of cirrostratus. By 1:00 PM a 6-hr maximum of 37F was recorded along with a minimum of 20F. Today’s Observations: 7 A.M.
