NORTHWESTERLY WINDS MAINTAINS COLD AND DRY CONDITIONS WITH
INCREASING SUNSHINE TODAY….
This morning featured mostly cloudy conditions and a strong northerly
wind. As the day continued, skies have started to clear more and the
temperatures have steadily risen to the upper 30s by the afternoon.
While it has been a cold day on the summit, the sunshine makes it at
least somewhat more tolerable.
Temperatures dipped to below freezing early this morning, with a low
of 24F. With the steady northerly winds at the time, we were experiencing
wind chills in the mid to upper teens. Fortunately, there has been
plenty of sunshine, and with continued dry conditions the temperatures
have recovered nicely. Dew points have continued to drop as the day
progressed, starting at 10F and dropping down to single digits by 1pm.
This combination of lower temperatures and even lower dew points has made
today feel bitter cold at times.
Winds have continued to be predominately out of the north today, with
the north-northwest winds shifting slightly to the northwest by the
afternoon. The average speed for the day so far is around 10mph. The peak
gust so far for the day is 27mph occurring at 12:14pm this afternoon.
The visibility has been decent today, as the colder, dry air has
remained in place throughout the day. Visibility has remained in the
50-60 mile vicinity today.
The maximum temperature so far today is 37F degrees, which is 11 degrees
below the normal high of 48F. The minimum temperature since midnight is
24F degrees, which is 7 degrees below the normal low of 31F.
