BLUE HILL METEOROLOGICAL OBSERVATORY 
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA

DAILY DISCUSSION AND CLIMATE SUMMARY
MONDAY, NOVEMBER 17, 2014    
ALL TIMES ARE IN EASTERN STANDARD TIME

COLD RAIN, THICK FOG ENSHROUD GREAT BLUE HILL MONDAY,
TWO DAILY RECORDS BEING WATCHED CLOSELY TODAY  

Rain that began early this morning was moderate to heavy between
7:00 and 11:00 AM EST this morning with thick fog reducing visibility
to 1/8 of a mile at times. An overnight low of 34F was not quite
low enough for any icing to occur. 

Rain has totaled 0.98 inches up to 1:00 PM EST this afternoon,
and may threaten today's daily precipitation record of 1.92 inches,
set back in 1920. With winds expected to increase later as well, our
daily record peak gust of 61 MPH, set in 2006, may also be in
jeopardy as an area of low pressure strengthens and passes through
the region later today.
