SPOKANE, Wash.—The historically harsh winter-weather maker in Spokane, is officially back, and it goes by one name: La Niña.
Sea surface temperatures of the central and eastern equatorial Pacific Ocean are considered to be below average.
The below average sea surface temperatures usually signify the start or occurrence of a La Niña pattern.
Moderate-to-strong La Niña winters have historically equated to above normal precipitation and below normal temperatures across the Inland Northwest.
Tom Sherry released above-average snowfall estimates in his 2017-2018 Winter Outlook at the beginning of the week.
According to long range climate models, there is now a 65-75% chance of continuing through the upcoming Winter. The La Niña could extend until February-April 2018.
