BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY THURSDAY, SEPTEMBER 26, 2013 ALL TIMES ARE IN EASTERN STANDARD TIME COOL AND DRY PATTERN CONTINUES WITH ANOTHER BEAUTIFUL FALL DAY High pressure has been dominating the weather for the past couple of days, making it cool and dry here at the summit. Yesterday was the fourth consecutive day of below normal temps. Today begins a slight warming trend, with a low of 52 degrees, 1 degree above the average for the date. This morning was cloudy with a clearing line visible to the NE. This line of clearing moved in the area, causing us to have bright sunshine around the noon hour. This has caused our temperatures to rise into the upper 50s to low 60s. It has made for a beautiful fall day. The pattern has made for some very nice weather, but it has been dry. Even though September is running above average for rain, some is needed. Most of the rain was received on the 1st of month, and was the only day we had above an inch. If the pattern continues, the month could finish only normal to slightly below for rain. Today’s Observations: 7 A.M.
