BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY MONDAY, NOVEMBER 11, 2013 VETERANS DAY ALL TIMES ARE IN EASTERN STANDARD TIME FIRST ARCTIC AIR MASS OF SEASON TO ARRIVE LATE TODAY OR EARLY TOMORROW WITH GUSTY WINDS HIGH PRESSURE OF 1041 MBS ALONG U.S. CANADIAN BORDER ALONG NORTH DAKOTA BORDER A strong Arctic cold front is expected to pass by early tomorrow with falling temperatures which could approach 20 degrees by Wednesday morning.  The record low temperature for November 12 is 18F in 1926 and 13 November is 14F in 1920. Yesterday’s rainfall of 0.08 inches did little to help our growing precipitation deficit, as we remain locked in a dry pattern with little precipitation expected this week.  A yearly precipitation surplus that topped 5.50 inches in early September is now a deficit of over 1.50 inches, and this deficit will likely continue to grow during the mostly dry conditions expected for the next several days. Today’s Observations: 7 A.M. Weather: Clear, stratocumulus distant SW-N-ESE, few lower cumulus fractus W-WNW, few lower cumulus ENE-E, cirrus distant SSW-SW Temperature: 37F; Dew Point: 25F; Wind: WNW at 14G20 kts, Wind: Peak wind WNW @ 26 kts @ 6:09 A.M., Wind: Direction variable WSW-NW Sea-level pressure: 30.06 ins.
