BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA FRIDAY, NOVEMBER 12, 2021 ALL TIMES ARE IN EASTERN STANDARD TIME SUNRISE: 0632E SUNSET:  1625E DRY STREAK ENDS - DREARY, WET, AND WINDY ATOP THE HILL... Clouds associated with an approaching low spilled into the region overnight. A colorful sunrise was witnessed, but faded quickly to a thickening cloud deck. The morning was primarily dry, but featured escalating winds. Winds speeds are now averaging 21 MPH with a peak gust clocking in at 54 MPH from the SSE! As we approached early afternoon, heavy rains scooted in. Thus, today concludes the 11-day dry streak. In fact, this is the longest consecutive period without any measurable or  even a trace of precipitation this year! It was certainly a welcomed experience following several wet months. Coinciding with the return of rain is the return of muggy dew points. So far today we have observed dew points in the upper-50s! Rain is expected to exit around dinner time along with falling temperatures and dew points.  The high so far today is 59F, 8 degrees above the normal max of 51F. The low since midnight is 46F, 11 degrees above the normal low of 35F. -------------------------------------------------------------- PRELIMINARY STATS FOR OCTOBER 2021 TEMPERATURE, Deg. F Avg.
