...TYPICAL AUTUMN TEMPERATE RAINFOREST WEATHER FOR OCTOBER FOR SE
AK...

The average daily temperature difference was less than a degree from
normal for all 4 Southeast Alaskan climate sites, and it was wet for
3 out of the 4 locations.  The only exception was Yakutat Airport,
which was 3.73 inches below normal for the month.  The other
locations were either near normal(Juneau Airport) or slightly above
normal(Ketchikan & Sitka Airports).  The reason for this monthly
liquid equivalent precipitation total distribution is that we had
more Atmospheric River tracks aimed toward the southern half of the
Panhandle for October than we typically see.  Juneau Airport
reported 1.7 inches of total snow accumulation for the month.  This
is 0.8 inches above normal.

As for records, Juneau Airport tied their old snow accumulation
record of a trace on the 17th, which was originally set in 2012.  On
the 20th, Juneau Airport broke its low temperature record for the
day by 1 degree with 22 degrees, which was set back in 1961.  On
that same day, the Sitka Airport tied their low temperature record
with 31 degrees that was also originally set back in 1961.  On the
21st, Juneau Airport broke its low temperature record for the day by
4 degrees with 20 degrees, which was set in 2020.  On the 29th,
Yakutat Airport broke their daily liquid equivalent precipitation
record of 2.31 inches with 3.78 inches, which was set back in 1957.
