...ABOVE NORMAL TEMPERATURES AND BELOW NORMAL RAINFALL FOR SE AK FOR
JULY...
For the vast majority of the month, ridges of high pressure,
generally offshore flow, and warm air advection dominated the
weather over the Panhandle, which kept surface conditions dry, skies
clear to partly cloudy, and temperatures warm for the month.
Therefore, for all 4 climate sites, the average monthly temperature
was above normal and the total monthly precipitation was below
normal for the month of July. We had a small handful of relatively
quick-moving weather systems scattered throughout the month that
generally brought mostly cloudy to cloudy skies and rain to SE AK
and kept temperatures moderated for those days, but not enough to
bring any of the climate sites up to normal for rainfall or down to
normal for temperatures.
Additionally, Sitka Airport tied their record high temperature of 73
that was previously set back in 1994.
