BLUE HILL METEOROLOGICAL OBSERVATORY
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA
SUNDAY, AUGUST 21, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0458E
SUNSET: 1836E
WARM AND BECOMING LESS HUMID THIS P.M. WITH A SOUTHERLY BREEZE….
After yet another day of 90+ yesterday, today the temperature has
maxxed out in the mid-upper 80s. The lower temperatures are due in
part to some thicker cirrostratus clouds moving over the region
early this afternoon, and thanks to the wind that is south-
southwest to at times south. This helps to pull slightly cooler
air up from off the south coast. So as it stands right now, we
will not have a heat-wave here on the hill this weekend.
Speaking of yesterday, the high was 94F degrees which set a new
max record for the day. This beat the old record of 93F set back in
1937!
As mentioned, the wind has become gusty this afternoon after being
on the light side this morning. The average speed for the day thus
far is around 9mph. However gusts between 25-30mph have occured
early this afternoon.
We continue to be on the very dry side in terms of rainfall. As
noted over previous days, most of the Boston area remains under
extreme drought conditions, as reported by the National Drought
Monitor. The total rain deficit on the year currently stands at
11.67 inches below normal. The trees and plants here on the hill are
showing definite signs of distress, with many leaves having turned
brown and/or fallen off as if it were late October.
The high so far today is 87F, which is 7 degrees above the normal
maximum of 80F. The low since midnight is 66F, which is 4 degrees
above the normal minimum of 62F.
