A SLIGHT WARM-UP WITH LIMITED VISIBILITY FROM THE
SUMMIT….

Today we observed 50 miles of visibility on average
and a thin overcast consisting of all upper-level
clouds. Wind was westerly and on the lighter side,
with an average speed around 10 mph and a max gust of
18 mph seen earlier this morning.

Warmer air is being brought into the region, as our
snow depth hangs on for dear life at just under an
inch.

The high so far today is 38F, 3 degrees below the normal
maximum of 41F. The low since midnight is 18F, which is
6 degrees below the normal minimum of 24F.
