November outlook: Expect big temperature swings but near-normal conditions overall
'We’ve seen a variable fall with a mix of cool snaps and extended warm interludes. November looks to offer more of the same with a blend of mild and cold conditions. Averaging it all together allows us to forecast a November that is near to slightly warmer than average and near average for precipitation.
While variable weather patterns keep forecasters on their toes, there’s something for everyone, whether your preference is unusually mild days or more of a crisp autumn chill. The first week of the month will be a perfect example of this, with very chilly conditions early in the week, followed by an impressive warming trend. Then, by mid-November, there are signs of another cold snap.
Washington’s average November temperature is 49.6 degrees, and we believe this November will range from 49 to 51 degrees. Most days should see highs between 50 and 70 and lows in the 30s and 40s. November is typically the driest of the fall months, with an average of 3.17 inches, and this year we foresee amounts in the 3- to 4-inch range (lower than October).
Strengthening La Niña favors mild weather
A key factor in our November thinking is the strengthening La Niña event in the central Tropical Pacific. Waters are cooling in that area, and the latest observations suggest that we could experience our first strong La Niña November in about 10 years.
Since 1950, we have experienced eight strong La Niña Novembers.'>>>
