BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA SUNDAY, AUGUST 23, 2020 ALL TIMES ARE IN EASTERN STANDARD TIME RECORD WARM AND HUMID UNDER A MIX OF SUN AND CLOUDS… A rare complete undercast was observed early this morning as low-lying dense fog settled over the countryside below the summit, while here on top it was mainly clear and sunny. Undercasts are rather common phenomena in mountainous areas, however here at Blue Hill, at only 635ft in elevation, it’s much less common and a thrill when it happens! After that excitement early this morning, the day has been rather quiet. A mix of sun and clouds has been the theme with very light and variable wind all morning. Finally as we’ve moved into the mid afternoon hours, an increasing south wind has taken over with gusts upwards of 23 mph so far! This southerly flow is helping to pump low level moisture into the region as reflected with the dew point sitting in the mid to upper 60s, making it feel rather humid. We’ve reached 89 degrees so far today, this has broken our record high for the day. The previous record as only 88 degrees set in 1918, 1947, 1949, and 1996! The high so far today is 89F, 11 degrees above the daily normal maximum of 78F. The low since midnight is 64F, which is 3 degrees above the normal minimum of 61F. Today’s Observations: 7 A.M. Weather: Undercast, scattered stratus fractus, scattered altocumulus and altocumulus castellanus, thin scattered cirrus Temperature: 69F; Dew Point: 66F; Relative Humidity: 90% Wind: E at 2 kts, wind light and variable Sea-level pressure: 30.08 ins.
