BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY FRIDAY, NOVEMBER 15, 2013 ALL TIMES ARE IN EASTERN STANDARD TIME STRONG TEMPERATURE INVERSION THIS MORNING; TEMPERATURES MODERATING NICELY WITH VERY DRY AIR MASS A strong temperature inversion was quite apparent by taking a look at morning lows this morning: Blue Hill 38F, Hingham 28F, Plymouth 26F, and nearby Norwood 21F. It was cold enough in the lower elevations for a thin layer of ice to form and cover about 10-20% of Ponkapoag Pond. Some impressive looming of the distant mountains also occurred this morning with the temperature inversion, making the mountains look much larger than reality. Temperatures have warmed up nicely this afternoon, nearing 60F here on the summit. Today is a solid 10 degrees warmer than yesterday, and will likely finish several degrees above normal for the date. The air mass is very dry despite persistent SW winds today. Dew point temperatures have been down in the teens to near 20F, producing very low relative humidity this afternoon of 20-25%. Today’s Observations: 7 A.M. Weather: Scattered altocumulus, broken thin cirrus, few cirrocumulus, inversion present, small smoke plume distant S drifting ENE, thin smoke layer distant all quadrants, distant haze Temperature: 40F; Dew Point: 15F; Wind: SW at 12 kts.
