...After a stretch of near climatic normal weather in Southeast
Alaska, June finished hot and dry...

A quick glance at the monthly climate statistics for June reveals
slightly above normal temperatures and above normal precipitation
for many locations. The actual story is a tale of two weather
patterns. The first part of the month was influenced by a series of
weather fronts and onshore flow. The final third of the month saw
rising temperatures and mostly dry conditions due to a strong
blocking ridge of high pressure over the gulf. Also of note during
the month, a few thunderstorms developed and moved across parts of
the panhandle. The Juneau WFO issued its first severe thunderstorm
warning on record June 27th for the Misty Fjords.

Average monthly temperatures were warmer than normal for all four
climate sites with departures from normal ranging from 1.0 degrees
in Sitka to 4.2 degrees in Yakutat. Both the high and low
temperatures averaged above normal temperatures for the month.
Multiple record high temperatures were recorded during the final
five days of June. On the 27th Yakutat tied its highest all-time
temperature of June at 87 degrees, which is the 2nd warmest day ever
there. This was also the warmest June on record in Yakutat. Juneau
also saw its share of warm temperatures, surpassing the 70 degree
benchmark 9 days in June, including 7 days in-a-row to finish the
month. Juneau also set record high temperatures on the 27th, 28th
and 29th when the temperatures rose to 81, 85 and 84 degrees
respectively. On June 29th downtown Juneau broke a record dating
back to 1909, recording a high temperatures of 83 degrees.

Although finishing the month dry, June was wetter than normal for
most locations in Southeast Alaska. One exception to this was
Yakutat which recorded a nearly 3 inch deficit from normal, nearly
half the normal rainfall for the month. Other locations received
normal precipitation values by mid-month, but not much more rain
afterward. Departures from normal for these sites ranged from 0.3"
above normal in Juneau to 1.37" inches above normal in Ketchikan.
While the slightly above normal rainfall for June was beneficial,
much of the southern panhandle still remains in severe to extreme
drought. Abnormally dry conditions continue to persist north of
Frederick Sound through the western shore of Yakutat Bay. Daily
rainfall records were also set this month. On June 17th Juneau tied
a daily maximum of 1.17" and Haines set a new record of 1.08". The
next day, June 18th, Sitka recorded a record daily rainfall of 0.83".
