DAILY DISCUSSION AND CLIMATE SUMMARY

ALL TIMES ARE IN EASTERN STANDARD TIME

ARCTIC COLD AND BITTER WIND CHILLS ON STRONG WEST WINDS…

Behind the powerful storm of two days ago, strong winds have pulled
Arctic air down into New England this weekend. The low temperature
was 2F this morning, and with a sustained wind speed of 22 mph at
7 AM, this produced wind chills near -20F at sunrise today. As of
early afternoon, the temperature had climbed to only 9F, and that
is the high temperature so far today. This is well above the record
low maximum temperature for January 6 of 3F set in 1896. The record
low for today of -14F in 1896 was well out of range, but the record
low temperature for January 7 of -7F, also set in 1896 may be
reached tomorrow morning. Strong winds have continued today out of
the west with two peak gusts of 43 mph out of the west at 12:45 PM
and 1:20 PM this afternoon.  Drifting snow has been severe in the
instrument enclosure and in the upper sections of the summit access
road today with over two foot drifts in the road this morning.
