DAILY DISCUSSION AND CLIMATE SUMMARY

ALL TIMES ARE IN EASTERN STANDARD TIME
RELENTLESS SNOW FALLS HEAVILY FROM EARLY MORNING

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

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.
