BLUE HILL METEOROLOGICAL OBSERVATORY
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA

DAILY DISCUSSION AND CLIMATE SUMMARY
MONDAY, JUNE 23, 2014
ALL TIMES ARE IN EASTERN STANDARD TIME

DRY AND PLEASANT ONCE AGAIN ON GREAT BLUE HILL

High pressure is dominating the weather once again today,
with temperatures warming to the warmest readings we have
seen in the past few days at 80F.

Continued dryness has deepened the month’s precipitation
deficit to 1.47 inches. With one week to go, it appears likely,
barring a few strong downpours that June will end on the dry
side of the norm.
