...Warmer than normal April with mixed results on precipitation...

The perception by most residents of Southeast Alaska is probably one
of a significantly cooler than normal April with far greater than
normal precipitation. This perception is no doubt influenced by the
extraordinarily warm and dry weather a month ago in March. In
actuality, all 4 climate sites recorded average April temperatures
of around 1 degree F or more above normal.

Precipitation patterns were variable, but the clear trend was for
more precipitation farther south and less to the north. Apart from
Yakutat, which recorded less than 70 percent of normal for the
month, the three remaining climate sites all exceeded normal April
values. So yes, April did feature "generally" greater than normal
precipitation, but perhaps not as much as what was generally
perceived. As indicated above, departures from normal in the
positive sense were greater in the southern Panhandle and Ketchikan
recorded more than 146% of normal. In fact, for accumulated
precipitation since January 1st, Ketchikan is now closest to normal
than any of the other three sites, though all are still below
normal. One notable exception to this generalization is Klawock,
which only saw 72% of their normal April precipitation. This makes
April 2019 the 5th driest April on record in the 22 years of data
available for that town. In terms of drought relief, April`s
precipitation did not really do anything to alleviate the drought in
the southern Panhandle that has been going on for over a year, but
at least the situation did not get any worse this past month.

The end of April marks the practical end of the snow season for
Southeast Alaska and three of the four primary climate sites did see
some late season snow. Sitka recorded two days, Juneau saw snow on
three days, and Yakutat reported snow on six separate days. In the
Juneau area, total snow for the month was well below normal with
only 0.1 inches recorded at the airport and 0.5 inches in the back
of the Mendenhall Valley at the forecast office. While not an
official climate site, a weather spotter in Gustavus did report
having 3 inches of new snow in their back yard one morning.
