BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY TUESDAY, AUGUST 13, 2013 ALL TIMES ARE IN EASTERN STANDARD TIME LIGHT RAIN AND SHOWERS PROVIDE ONLY 0.02 INCH OF PRECIPITATION; RELATIVELY COOL AND CALM OTHERWISE Light rain showers began on the summit just before 9 A.M. EDT, remaining relatively light and intermittent until about 11:30 A.M. EDT. At that point, steadier light rain began falling and lasted through about 2 P.M. EDT. The total rainfall today has only reached 0.02 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 much of the day. While the low temperature this morning only managed to reach 65F (normal 62F), the high temperature has struggled to reach the lower 70s this afternoon. Today will likely finish a few degrees below the 30-year normal. Interestingly, Monday was the first day since July 29 that the average daily temperature actually finished above the 30-year normal for a given date. As has been the case over the past couple of days, today winds continue to be rather light. The wind direction has gradually backed today, from a SW direction early this morning to a SE direction this afternoon. Today’s Observations: 7 A.M.
