A frontal system with a relatively decent tropical moisture fetch moved through the area around the 5th, bringing the most appreciable rainfall to the Panhandle. On that day, Juneau Airport set a new daily rainfall record with 0.77 inches, breaking their previous record of 0.72 inches, which was set back in 1955. A few relatively quick-moving and weak frontal systems gave light and short lived rain events and post frontal showers, primarily during the first third to half of the month. During that timeframe, Southeast Alaska received the vast majority of its precipitation. There was primarily blocking high pressure in place around our region, dominating the weather for most of the month, giving decreased clouds, drier weather, and increased daytime high temperatures from all of the excessive sunshine, which made the monthly average temperatures across the Panhandle a bit above normal. On the 19th, both Sitka and Yakutat Airports set records for high temperatures. Sitka's new record is 65, breaking their old record of 61, set in 2021. Yakutat's new record is 64, which broke their old record of 60, also set in 2021. On the 20th, Ketchikan, Sitka, and Yakutat Airports broke high temperature records. Ketchikan's new record is 65, breaking their old record of 64, which was set back in 1934. Yakutat's new record is 61, which broke their old record of 58, set back in 1989. Sitka's new record is 63, breaking their old record of 61, which was set back in 1978. Additionally, Juneau International Airport received 0.2 inches of snow accumulation on the 1st of the month and several traces after that, before mid-month, primarily from isolated to scattered post- frontal nocturnal snow showers.
