BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA MONDAY, FEBRUARY 2, 2026 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0657E SUNSET:  1700E ABUNDANT SUNSHINE AND LESS COLD, BUT STILL BELOW NORMAL…. Today has featured a great deal of sunshine through some high thin cirrus clouds. With lighter wind and less cold temperatures, it actually feels rather nice out there today compared to recent days. The temperature has reached the low 30s early this afternoon. This is the first day to reach 30F since January 23rd, when we had a high of 32F. We are currently running a streak of 11 days with readings at or below the freezing mark (much of that time well below). Dew point values have been very gradually rising through the single digits today, indicative that the arctic air mass continues to linger for now. Winds have been much lighter today, mainly out of the northwest. The average speed for the day so far is around 13mph, but the trend has been for decreasing speeds as we work into the early afternoon hours. Gusts were strongest during the week hours of the day, the peak gust for the day occuring around midnight with a value of 25mph. Visibility has been excellent today, with the view holding between 60-70 miles all day. The maximum temperature so far today is 31F degrees, which is 4 degrees below the normal high of 35F. The minimum temperature since midnight is 11F degrees, which is 7 degrees below the normal low of 18F. ————————————————————– PRELIMINARY STATS FOR JANUARY 2026 TEMPERATURE, Deg. F Avg.
