DAILY DISCUSSION AND CLIMATE SUMMARY

ALL TIMES ARE IN EASTERN STANDARD TIME
RELENTLESS SNOW FALLS HEAVILY FROM EARLY MORNING
THROUGH EARLY AFTERNOON. NEW STORM TOTAL OF 22.6 INCHES

Snow which fell nearly continuously yesterday,
continued overnight, becoming heavy by 8:00 AM EST. Steady
winds have drifted snow on the summit, which had an
apparent average snow depth of 37 inches by the 1:00 PM
EST observation, though many areas have drifted much higher.
With storm after storm pounding the area, Blue Hill
Observatory has unofficially broken a record through
today’s 1:00 PM snowfall measurement for the snowiest
January and February on record. With January’s total of
42.9 inches and February’s of 42.6, as of 1:00 PM with
moderate to heavy snow still falling and plenty of days
left in the month, 85.5 inches of snow beats out the
previous record of 77.9 inches set in 1948.
