Storm Impacting the Northwest U.S.; Fire Weather Conditions in Southern California; Severe Weather in the South

A Pacific storm is bringing areas of low elevation rain, moderate to heavy mountain snow, and high winds to the Northwest. Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >

November 2018 changed little from the month before, as in temperatures remained relatively chilly on a whole. The area ranged from 2 to 8 degrees below average, with northeastern South Dakota and western Minnesota being the coolest. Sisseton recorded their 6th coldest November on record, and Wheaton tied for their 5th coldest. Aberdeen, Watertown, Sisseton and Pierre recorded either record cold lows or highs on November 9th, and additional cold records were set on the 17th and 10th across the area.

No blockbuster winter storms impacted the area this November (historically, November is one of our snowiest months), but there were a number of wintry precipitation events that led to difficult travel. Namely, a swath of generally 2-6 inches (locally higher) of snow impacted north central and northeastern South Dakota and west central Minnesota on the 16th. Additionally, light freezing rain impacted the area on the 28th and freezing drizzle impacted mainly central South Dakota on the evening of the 16th.
