BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY THURSDAY, SEPTEMBER 19, 2013 ALL TIMES ARE IN EASTERN STANDARD TIME CLEAR  AND CALM BEAUTIFUL WEATHER CONTINUES!! A SECOND DAY OF PERFECTLY CLEAR SKY This morning had no clouds and perfectly clear. The visibility was high around 80 miles in all directions. Pollution was visible over the city of Boston during the early morning hours and into the afternoon. This would indicate that there was a pretty strong inversion, which is helping with the clear skies. Another indication of the inversion is that the Hingham station was 46, Taunton was 40, and Norwood was 38. The low temperature here was 51F. Temperatures were increasing with height, Worcester, was also 51 degrees. With bright sunshine we were able to warm up to 76F. This would continue the trend of running below to near normal. Yesterday was the 5th day in a row of being cooler. The month as of right now is running about a degree below normal. An interesting note is how calm our winds are today. We had a gust of 17 mph at around 4am this morning. Winds have weaken since then. We are averaging only around 5 mph this afternoon. This is most likely due to a strong high pressure system that has been dominating our weather. We had our highest pressure on Tuesday at 30.44 inches of Hg. This was the highest pressure recorded since May! However we have since dropped since then but still running at 30.11 inches of Hg. Its rare to have two consecutive perfectly clear sky days in the observations from Blue Hill.  There was a tiny bit of cirrus or cirrostratus in the distant SE-SSE sky yesterday.
