BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY SATURDAY, NOVEMBER 2, 2013 ALL TIMES ARE IN EASTERN STANDARD TIME OCTOBER FINISHES 7TH DRIEST ON RECORD WITH 1.09 INCHES AND WARMER THAN AVERAGE… VERY LITTLE WIND TODAY AFTER GUSTS TO 60+ MPH ON FRIDAY… The wind has diminished substantially from yesterday when we recorded a peak gust on our official wind recorder to 60 mph SSW at 11:08 AN EST.  A total of 614 miles of wind were measured on Friday, which translates to an average for the day of 25.6 mph.  The peak gust today has been only 18 mph from the WSW at 12:15 AM EST. In contrast to yesterday, only 68 miles of wind have passed by the Observatory from midnight to today through 1 PM EST for an average of 5.2 mph today.  The temperature has climbed once again to the middle 60s, with the dew point dropping into the upper 30s, making for a beautiful day.  Colder weather is expected to return with the passage of an approaching cold front tonight or early on Sunday.  There were frequent instances of colorful and bright iridescence within the high and middle clouds around the sun at mid-day today.
