A weather pattern heavily influenced by the strong El Nino brought much wetter and warmer weather to Southeast Alaska for the month of November. Multiple strong Gale and Storm-Force frontal systems affected Southeast Alaska with strong southerly flow, warm air advection, and plenty of precipitation. Around mid-month, cold, northerly outflow from a strong area of high pressure located over the Yukon established cold temperatures in the lower and mid levels of the atmosphere. This atmospheric setup preceeded a strong frontal system approaching from the south, resulting in a classic overrunning scenario. On the 20th, A storm force frontal system moved into the Panhandle, bringing high winds and blizzard conditions to the Downtown Juneau and Douglas area. Much of the remainder of the Panhandle received heavy snowfall that day before post frontal warm air displaced the much colder near surface airmass. As is usually the case in Southeast Alaska, post frontal precipitation transitioned from snow to rain from south to north. The southern third of the Panhandle received heavy rain and high winds from that storm. Prince of Wales Island encountered a series of minor landslides on the 20th. Late that same night, the city of Wrangell experienced a tragic and devastating landslide due to the heavy rain and strong winds associated with that storm. While much of the month recorded above normal temperatures, daily averages in the middle of the month and then again at the end were much more seasonable. On Wednesday, November 8th, both the Juneau and Yakutat Airports set new daily high temperature records. Juneau recorded 50, which broke their old record of 49 set in 2016, and Yakutat recorded 55, which broke their old record of 52 set back in 1930. Chambers/Fritsch $$
