...WINDY, WARM AND RAINY START TO NOVEMBER...

Numerous high wind events occurred during the first two weeks of the
month, accompanied by a lot of precipitation in the form of rain
across the panhandle. There was also heavy thunderstorm activity of
near super cell intensity during the third week of November. Hail
was reported at multiple sites on the both the 10th and the 11th of
the month.

Temperatures during the first half of the month trended well above
normal for both daytime highs and overnight lows. Beginning with the
third week of the month, daily average temperatures began falling -
first down to normal, and then below normal by the start of the 4th
week of November. Departures below normal were more notable over
northern locations and near the coast mountains. This occurred
primarily due to a protracted but fairly weak outflow event that
dominated southeast weather for much of the second half of the
month. While no high wind events occurred, there were several
episodes of strong winds with northerly gales over the far northern
inner channels.

The cold surface air was followed by a weak overrunning event which
allowed for the second accumulating snow event for much of the
panhandle between the 21st and the 23th of the month. As is
typically the case with such overrunning events, the cold near-
surface air was slowly scoured out, raising average temperatures up
to near normal values for late November and transitioning snow
showers to rain showers.

The month ended much as it began with a high wind event that
affected the southern panhandle most severely. Additionally,
significant snowfall accumulated along both highways.
