BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY TUESDAY, SEPTEMBER 24, 2013 ALL TIMES ARE IN EASTERN STANDARD TIME COOL, RELATIVELY CALM, AND MOSTLY CLEAR The low temperature this morning of 40F tied the lowest temperature observed so far this Fall season which also occurred only one week ago on the 17th. The afternoon high may reach the mid 60s, but the average temperature for today is will end up several degrees below the 30-year normal for the date. That will push the month of September thus far to 1.0 degree below the 30-year normal. Only a few small cumulus have dotted the sky today along with some high cirrus. The clouds have mostly been to the N through E of the observatory. Winds have been calmer today compared to the past few days, generally averaging around 10-15 mph, with a few gusts near 20 mph. Visibility continues to be great, although some light distant haze has brought it down to 80 miles rather than the 90 miles of yesterday. Today’s Observations: 7 A.M. Weather: Scattered thin cirrus, few cumulus distant NE-S and distant WNW-NNW, cirrus distant NNE and distant SW-WNW, thin smoke layer along horizon all quadrants Temperature: 43F; Dew Point: 39F; Wind: W at 10 kts.
