VERY CHILLY WITH EXCELLENT VISIBILITY ON THE SUMMIT….
Skies were partly cloudy and the visibility was 80 miles, the
weather was incredibly cold. We started off this morning at 2F,
and reached 12F by 1 P.M. The record low maximum for the date is
5F set in 2004.
A pressure spike was seen on our charts around 7 A.M. this morning,
could that be from the volcanic eruption in the Pacific?
The high so far today is 13F, which is 21 degrees below the normal
high of 34F. The low since midnight is 1F, which is 17 degrees below
the normal low of 18F.
