BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY WEDNESDAY, AUGUST 14, 2013 ALL TIMES ARE IN EASTERN STANDARD TIME VERY SUNNY, BECOMING WINDY, COOL FOR MID-AUGUST AND DRY REFRESHINGLY COOLER AND DRIER AIR ARRIVES EARLY THIS MORNING WITH DEW POINTS FALLING FROM THE LOW 60’S IN THE FIRST THREE HOURS OF THE DAY TO 49F BY 8 A.M. Today is another one of already several very sunny days this month.  Winds have increased from the WNW and are gusting over 30 MPH by early this afternoon.  The new cooler and much drier air mass which arrived early today is keeping high temperatures in the lower 70’s or close to 10 degrees cooler than normal while the dew point remains near a comfortable 50F.  Visibility of 75 miles early this morning has decreased slightly to 65 miles by early this afternoon. The air mass change from moderately humid to much drier early today was rather dramatic with dew point falling from the low 60’s during the pre-dawn hours down to 49 degrees by 8 A.M. EDT observation time.  The arrival of the new air mass was only accompanied by some cloudiness and gentle to moderate winds from the west-northwest. Visibility was up to 75 miles by 8 A.M. EDT and still increasing. A period of light rain and rain showers around mid-day yesterday lasting into the afternoon provided a mere 0.02 of an inch.  A large batch of heavier rain and embedded t-storms spread to our north, and especially to our south, leaving us in a lull of light rain. However, radar reports of heavier rain on Cape Cod were misleading so except for the Islands south of the Cape, most of Cape Cod received less than a quarter of an inch of rainfall! Interestingly, Monday of this week was the first day since July 29 that the average daily temperature actually finished above the 30-year normal for any given date. Today’s Observations: 7 A.M.
