BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA MONDAY, NOVEMBER 11, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0631E SUNSET:  1625E OVERNIGHT RAIN SHOWERS END, CLOUDS AND SOME SUN REMAIN WITH CONTINUED MILD TEMPERATURES…. We finally got a little rainfall overnight, but it didn’t amount to much with only 0.08″ being measured. This is also the total for the month to date, which is 1.38″ below normal. We’ll take what we can get, but this obviously didn’t do much to improve the drought conditions across the region. As such, caution will still need to be taken with any outdoor burning, which is simply not recommended at all for the time being. A mix of sun and clouds has been the theme through the day as diurnal heating helps to develop stratocumulus that are dotting the brilliantly blue sky. Temperatures are still mild for this time of year with the overnight low still a solid 15 degrees above normal. Readings have reached the mid 60s early this afternoon which is a solid 10+ degrees above the seasonal levels expected for this date. The wind remains on the busy side with a west to west-southwest flow averaging around 17mph so far for the day. Frequent gusts over 25mph have been occurring as well, with a peak gust so far for the day of 40mph, which occurred at 4:15am this morning. Visibility has been improving through the day, starting the day around 50 miles, and reaching 70 miles by 1pm observation. The maximum temperature for the day so far is 64 degrees, this is 12 degrees above the normal high of 52F. The minimum temperature since midnight is 50F degrees, which is 15 degrees above the normal low of 35F degrees. ————————————————————– Today’s Observations: 7 A.M.
