ALL TIMES ARE IN EASTERN STANDARD TIME (EST)

MAINLY SUNNY AND GENERALLY SEASONABLE HERE AT BLUE HILL….

A patch of mid level cloud cover moved through this morning,
otherwise it’s been a mainly sunny day with temperatures
rising to the upper 40s. All in all not a bad day for the big
travel day before Thanksgiving.

The wind has been busy at times mainly out of a northwesterly
direction. The average speed so far for the day is around
13mph, but is now showing some signs of slackening a bit as
we progress through the afternoon.

Visibility has been limited to only 30-35 miles thanks to
general haziness.

The high so far today is only 49F, which is 2 degrees above the
normal maximum of 47F. The low since midnight is 35F, which is
3 degrees above the normal low of 32F.
