POTENT COLD FRONT MOVES THRU LAST NIGHT, BLUSTERY AND CHILLY TODAY….

A potent cold front moved through last evening accompanied
by a strong squall-line that raced through just before 10pm.
A brief band of heavy rain showers along with strong winds
were the result. A wind gust of 59mph was measured here with
the squall. The line was moving so fast however, that only
0.08″ of rain was left in the gauge by the system.

Very mild air was in place ahead of the frontal system, as
such we recorded a new record high minimum for yesterday’s
date of 47F. This beat the old record of 43F back in 1894!

Cold air advection has been ongoing here today with a mix
of sun and clouds along with windy conditions. Temperatures
have only slowly recovered to the low 40s by early this
afternoon.

Winds have been averaging around 23mph for the day with frequent
gusts over 40mph.

Visibility has been excellent today with a view to 85 miles!

The high so far today, which occurred at midnight, is 47F, which
is 5 degrees above the normal maximum of 42F. The low since
midnight is 34F, which is 10 degrees above the normal minimum
of 24F.
