...Colder Than Normal Conditions Dominate the month of March...

The month began with a major snow event that included winter storm
warnings and advisories for northern Southeast Alaska. The maximum
reported values were 9 inches of new snow in Yakutat and 60-70 mph
wind gusts in Skagway, with high winds persisting there through
March 2nd. More winter storm warnings and blizzard warnings were
issuer for the northeast Gulf Coast and far northern inner channels
on March 4th. Also, a strong Arctic outflow event resulted in heavy
freezing spray in northern Lynn Canal as well as damage to trees and
structures on Shelter Island. The ferry Tazlina was also observed
during this event as being enshrouded in sea spray. Blizzard
conditions diminished, only to be replaced by wind chill advisories
for the Klondike Highway. The first week of March ended with the
noting of 49 consecutive days of trace or better precipitation at
Juneau Airport on March 7th. More snow arrived on the 8th of March
with accumulations ranging from 1 to 8 inches. By March 10th, the
entire state was finally declared drought free with no locations
even listed as abnormally dry-the first time since January 2018. By
mid-month, skies cleared. The sunny skies allowed for above normal
daytime highs and below normal overnight lows, which resulted in
daily average temperatures that were below normal for March.

In terms of snowfall, not that many records still exist due to an
automation of hourly and daily airport observations. There are,
however, a few non-airport sites that still report reliable snow
information. While the snow totals at the Juneau Airport have been
disappointing this season, the situation is quite different at
Eaglecrest. As of 01 March, the snow depth was 81 inches, the 4th
highest March 1st value in the past 44 years. NRCS data indicates
that upper elevation snowpack across much of Southeast Alaska is at,
or in some cases, well above normal. Hopefully, that will mitigate
the chances of drought conditions returning this coming summer.

The Vernal Equinox and the official start of Spring arrived with
sunny weather and daytime highs in the mid-40s to mid-50s. Soon
afterward, rain and cooler temperatures put a damper on Spring and
"Winter: Part 2" set in by the end of the month with either snow, or
clear skies and well below normal temperatures. The month ended with
another Winter-like event when high winds over the northern half of
the Panhandle ranged from 60 to 90 mph.
