Winter months 2022-23 overview: what to anticipate in Boise

October 31, 2022

After the remarkable “snowmageddon” of 2016-2017 with 39.1″ of snowfall in Boise, no surprise several of us are a little anxious regarding this coming wintertime.

BOISE, Idaho– This previous summer season was warm in Boise, with one of the most 100 ° + days ever before tape-recorded (27 days). September likewise saw blistering weather condition, with a 129-day stretch of heats, at the very least 70 ° or above in Boise– the second-longest stretch on document.

Yet after a scorching warm summer season, lots of have actually been doubting what to anticipate for this coming wintertime.

After the remarkable “snowmageddon” of 2016-2017 with 39.1″ of snow in Boise– almost double the seasonal snowfall standard– it is no surprise several of us are a little anxious regarding this wintertime.

KTVB got this inquiry with our message line:

” I was informed by numerous, numerous individuals that Idaho is mosting likely to have the most awful wintertime with snowstorms? Given that 1909! I’m going crazy.”

Yet that is speaking about snowstorms? To figure out, KTVB considered a couple of popular projections for wintertime 2022-23:

  • The Farmer’s Almanac, developed in 1818, states: The Much West and also the Pacific Northwest will certainly see about-normal wintertime rainfall; And also “Additional Flannels are Essential!” – a straight quote.
  • The OLD Farmer’s Almanac, developed in 1792, states: For the intermountain area, we can anticipate warmer than typical temperature levels, and also over typical rainfall. And also “anticipate cool and also snow from mid-November with very early February.” Seems like wintertime to me!
  • Accuweather states: The weather condition configuration will certainly be among one of the most complex and also vibrant in current memory because of every one of the weather condition consider play over the approaching months. Mostly because of the anticipated 3rd La Nina wintertime straight.

La Niña describes cooler-than-average sea-surface temperature levels throughout the east-central equatorial Pacific, rather than El Niño which represents warmer sea-surface temperatures.

The equatorial Pacific appears like it will certainly be awesome for an additional wintertime.

The National Oceanic and also Atmospheric Management (NOAA) concurs. There is a 75% opportunity of La Niña throughout the North Hemispheric wintertime, which would certainly be a La Niña “three-peat” (indicating our 3rd successive La Niña winter months).

That might imply there are some shocks in shop, because there have actually not been a great deal of winter seasons on document that were a 3rd La Niña straight– however, those couple of analog winter seasons did finish with near-average snowfall for Boise. Those winter seasons are 1954-57, 1973-76, and also 1998-2001.

An additional trustworthy resource for a long-range overview would certainly be the Environment Forecast Facility (CPC), a department of the National Weather Condition Solution. The CPC temperature level overview for December, January and also February reveal equivalent opportunities of above or below-average temperatures for Southern Idaho. The rainfall overview reveals a small favor above-average rainfall, with an also much better opportunity in the main hills.

So, what is our KTVB overview for wintertime 2022-23?

Bear in mind, the self-confidence and also precision of weather prediction lower the additional out the projection duration is. The following 7 days? We get on top of it. Past that? Some obscure ideas. A seasonal projection? Anticipate a really basic concept.

We will certainly need to see exactly how November goes, however presently our reasoning is that we will certainly wind up with an additional year of near-average snowfall for Boise (around 20″ for a period overall), with somewhat above-average snow in the hills. Fantastic information for skiers and also terrific information for farmers.

Yet will it be the most awful wintertime because 1909? Uncertain. To relieve your wintertime fears, obtaining a repeat of a snow-blitz wintertime like 2016-2017, has just regarding a 9% opportunity of occurring in any type of provided wintertime.

The ordinary seasonal snow for Boise is around 20″, however it will certainly not all come with as soon as. What we ensure when it concerns the wintertime overview: anticipate winter and also snow. Additional flannels are a great concept, and also the First Alert Climate group will certainly be right here for you every action of the method.
