BLUE HILL METEOROLOGICAL OBSERVATORY
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA
DAILY DISCUSSION AND CLIMATE SUMMARY
SUNDAY, MARCH 29, 2015
ALL TIMES ARE IN EASTERN STANDARD TIME
CLEARING SKIES AFTER A DAY OF SNOW THAT PUSHED THE SEASONAL RECORD
EVEN HIGHER
Yesterday’s snowfall of 5.0 inches gives Blue Hill Observatory its first
new daily record for the month of March. The previous daily record
snowfall for March 28th was 3.0 inches set back in 1932. The new record
for most snow in a season now stands at 150.8 inches of snow. Skies
were quickly clearing at the 7 AM observation and no clouds were visible
at the 10 AM observation.
Clear skies and the strong sun have not warmed things up much as
temperatures have remained cold and did not go above freezing until after
the 10 AM observation, though they are beginning to warm up this afternoon.
The air has remained very dry all day with very light winds.
