BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY TUESDAY, FEBRUARY 18, 2020 ALL TIMES ARE IN EASTERN STANDARD TIME THICKENING CLOUD COVER, A TOUCH OF LIGHT SNOW…. Clouds have been the theme yet again, thickening and lowering through the morning. Some very light snow developed just before noon and has persisted into the early afternoon hours. There has only been a trace of snow thus far due to the very light rate of fall and temperatures above freezing. An onshore wind has slowly veered from the east this morning to southeast early this afternoon. This has helped to moisten the atmosphere. The dew point has risen from 21 early this morning to 30 early this afternoon. The high so far today is 37F degrees, this is exactly normal for the date. The low since midnight is 27F, 7 degrees above the normal daily minimum of 20F. Today’s Observations: 7 A.M.
