BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY SATURDAY, AUGUST 24, 2013 ALL TIMES ARE IN EASTERN STANDARD TIME ANOTHER BEAUTIFUL SUMMER DAY It has been another beautiful summer day today.  The temperature fell to 55F this morning, the coolest reading in over a week.  It has rebounded into the low 70s this afternoon, which is below normal for today’s date. In addition to these comfortable temperatures, the dew point has been very low today, falling from around 50F this morning to just under 40F by early afternoon, making the air feel very refreshing.  Dew points this low have not been observed since late May!  The sky has been mostly sunny all day, with only a few fair weather clouds.  Winds have been steady at about 10mph out of the N-E today, with a few gusts over 20mph.  Visibility has been good today, averaging about 75 miles.  Also of note today is the high barometric pressure, as the sea level pressure this afternoon has risen to 30.33 ins. Hg, the highest reading of this month so far. The dry stretch of weather continues, with no measurable precipitation recorded on the summit since 0.02 inches of rain fell August 13.  This is the longest such streak since we went 12 days without measurable precipitation from April 26 through May 7 of this year.  With no rain expected today or tomorrow, we are likely to tie that streak.  Despite the recent dry weather, the month is currently only a little over half an inch below normal, largely due to the 2.21 inches of rain on August 9.  That one rain event accounts for about 87% of the monthly precipitation so far. Today’s Observations: 7 A.M. Weather: Clear, few altocumulus castellanus NE-SE, few cirrus NE-SE Temperature: 61F; Dew Point: 50F; Wind: NE at 9 kts Sea-level pressure: 30.29 ins.
