DAILY DISCUSSION AND CLIMATE SUMMARY
FRIDAY, NOVEMBER 14, 2014   
ALL TIMES ARE IN EASTERN STANDARD TIME
 
A RECORD TYING SNOWFALL FOR THE DATE OF 3.5 INCHES
 
EARLY MORNING SNOWFALL REACHES 3.5 INCHES AT SUMMIT
EQUALS A 1997 RECORD FOR THIS DATE, ALSO 3.5 INCHES…
A GREATER SNOWFALL OF 8.1 WAS RECORDED NOVEMBER 12,
BACK IN 1987.  
 
The precipitation began as a mixture of rain and snow in the couple hours
before midnight last night and changed to all snow (accumulating) between
midnight and 1 A.M. A daily record equaling 3.5 inches was measured on the
snow boards at 7 A.M. (snow ended at 6:45 A.M.)
 
Snow accumulated very little on rocks and blacktop areas but was very
sticky clinging to everything including the trees making the summit appear
as a white "winter-wonderland". There was a 1.5-inch high collar of snow 
on the opening of the standard and recording 8-inch gauges.  
 
The temperatures dropped to 31.2 degrees during the snowfall and had
risen to 31.8 degrees by 7 A.M.
 
Temperatures had only risen to near 40 degrees by early this afternoon
with partly sunny skies and a chill NW wind gusting to 20 to 25 MPH.
Only about a patchy inch of the 3.5 inches which fell early today
remains this afternoon.
