...For February, warm and wet mid month, then Winter storms at the
very end...

Very little action weather-wise for much of February...except for
the middle of the month and then again at the very end of the month.

Daily average temperatures trended down during the first week of the
month and were generally below normal by the end of the week. A
significant and abrupt increase increase in temperatures then
occurred on the 10th of the month. Warmer than normal conditions
persisted through the 16th of February. At that time and for the
remainder of the month, daily average temperatures hovered at or
slightly below normal.

The first week of the month was also very dry. Precipitation
returned along with the warmer than normal temperatures on or
around the 10th of the month and was primarily in the form of rain
for central and southern locations. Yakutat, however, experienced
significant snowfall from the 8th through the 12th, and then again
from the 16th to the 18th. Not much snow fell after that time, but
enough did fall around the middle of the month that Yakutat actually
finished the month with slightly above normal accumulated snow. The
same can not be said for Juneau, which finished the month with only
4.1 inches of snow for the month instead of a more normal 16.8
inches. Annette remained on track for another record low snowfall
month until the very end of the month, when 7 inches fell on
February 28th and pushed that station above normal by over 2 inches
for the month. Major and ongoing winter storms heralded the end of
the month which lasted into the beginning of March.

High winds also affected the panhandle from the 11th through the
14th of the month.
