BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY FRIDAY, NOVEMBER 22, 2013 ALL TIMES ARE IN EASTERN STANDARD TIME 0.22 INCH OF VERY BENEFICIAL RAINFALL TODAY; DENSE FOG BEGAN SHROUDING SUMMIT LATE THIS MORNING; TEMPERATURES FAIRLY STEADY IN 40S WITH S-SW WIND Light rain began falling early this morning and remained steady through early this afternoon. A total of 0.22 inch of much needed rain fell today. The summit has been shrouded in dense fog since late this morning, reducing visibility to 1/16th of a mile. Early in the day, visibility was upwards of 25 miles in light rain. The overnight low temperature was relatively mild at 39F, or 7 degrees above the 30-year average for the date. The temperature has not warmed much this afternoon, reaching only the mid 40s, which is a couple of degrees below the 30-year average for the date. The wind direction became SW yesterday, allowing for temperatures to moderate nicely. A S-SW wind continues today which has helped keep temperatures somewhat on the mild side, although extensive cloud cover is greatly limiting the effect. In anticipation of the expected cold over the next few days, below are a few current cold temperature records that could be challenged: Nov 24 Record low maximum: 26F in 1936 Record low minimum: 7F in 1897 Nov 25 Record low maximum: 23F in 1938 Record low minimum: 13F in 1938 Today’s Observations: 7 A.M.
