BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA SUNDAY, FEBRUARY 15, 2026 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0641E SUNSET:  1717E MAINLY SUNNY TODAY WITH CONTINUED SEASONABLE TEMPERATURES…. Skies started the day on the clear side after some overnight clouds moved out prior to sunrise. As the day has progressed, a few stratocumulus clouds passed through during the mid morning period, but have since dissipated. However, high thin cirrus clouds are advancing into the region ahead of a storm system that will be passing to the south of the region tonight and tomorrow. All in all it’s been a rather decent day as the higher sun angle and a light wind helps it to feel “warmish” despite temperatures running close to normal. The temperature started the day in the low 20s and started to rapidly warm toward the mid 30s by mid to late morning, then generally leveled off there. Dew point values which started in the low 20s this morning have dropped to the mid teens by early this afternoon as some mixing from aloft started to take place. The wind was fairly steady overnight into this morning, then dropped off to light speeds by early this afternoon. It has also shifted from the west to now being out of the east, but was variable for a time in between. The average speed for the day is around 10mph, however it’s been closer to 5-6mph over the last couple of hours. The peak gust for today so far is 24mph, which occurred right at 10:45am this morning. Visibility was quite limited early this morning to only around 20-25 miles due to thin fog and haziness, but has improved markedly to around 70 miles by early this afternoon as the air mass dried out. The maximum temperature so far today is 35F degrees, which is 2 degrees below the normal high of 37F. The minimum temperature since midnight is 22F degrees, which is 3 degrees above the normal low of 19F. ————————————————————– Today’s Observations: 7 A.M.
