More Snow – Yes, Snow – On The Way for Northwest

15 Jun 2020, 6:10 am

The summer solstice is less than a week away, but it sure won’t feel like it across parts of the Pacific Northwest for much of this week.

Temperatures will be running far cooler than average as an upper-level low spins through the region, increasing rain and snow chances on Tuesday and Wednesday. Winter storm watches and winter weather advisories have been posted for parts of Montana’s and Idaho’s Bitterroot Mountains.

 

The primary time window for snow across the Northwest is expected to be on Tuesday night into Wednesday morning, when several inches of wet, slushy snow could pile up near places like Helena and Bozeman, Montana.

A sharp cold front attached to a strong area of low pressure will drop temperatures across the Northwest into Tuesday, ushering in an early-to-mid spring-like air mass. That’ll lead to a chilly rain at lower elevations and several inches of wet snow at the Northwest’s higher elevations, especially, again, in Montana and Idaho.

Here’s a chronological look at how things are expected to play out on Tuesday and Wednesday across the Northwest:

Snow totals are expected to potentially top a foot in the highest elevations of southwestern Montana and northeastern Idaho. That much snow on already leafed trees could lead to significant power outages and downed trees.

Snow could also dot the Teton and Big Horn Mountains of northern Wyoming and the Sawtooth Range of central Idaho. This’ll mostly take place Tuesday night and into Wednesday.

Temperatures on Tuesday are expected to plummet, and in some cases, highs could be running more than 20 degrees below average:

This is all part of a wild June across the Northwest, one that’s quickly alternated scorching heat with bitter cold. This month has played more like April, perhaps, rather than late spring or early summer. Take a look at Boise, Idaho’s month so far, in which cold and warm have quickly interchanged one another:

And the forecast reflects the fact that the June rollercoaster ride is expected to continue.

 

 

For places like Helena, Montana, where higher elevations outside of the city could pick up several inches of wet snow, temperatures will feel more April-like through Thursday, before temperatures rebound to more summer-like levels – just in time for Saturday’s summer solstice.

Chris doesn't remember a time when that he didn't love the weather. When he was five years old, he wrote his first words, "Partly cloudy", in Ms. Benn's kindergarten class. According to Chris, it's been a love affair ever since, from teaching himself how to read forecast models at age 12, to landing at WeatherNation. Growing up in Greenwich, Connecticut, he started to go after his lifelong drea... Load Morem of becoming a meteorologist by predicting whether or not there would be snow days - turning him into Greenwich High School's "defacto weatherman". He turned that snow day-predicting website into a front page story a local newspaper, which in turn earned him a look at WABC-TV in New York, where Chris did the weather live on-air at the age of 16. He attended Boston University, where he continued being a "weather nerd", performing weather updates on the campus radio and TV stations, and doing the daily forecasts for the student newspaper. Following his studies at BU, Chris worked at Mile High Sports and ESPN Denver for four years while pursuing his certification in Broadcast Meteorology from Mississippi State University. Chris is a huge sports fan, rooting for the Rockies, Nuggets, Broncos, Avalanche and UConn. He frequently find links between sports and weather, including an investigative analysis he did in 2013, finding trends between Peyton Manning's play and game time temperature (he doesn't like the cold). Chris also enjoys running, playing any sport, socializing and periodically overeating at all-you-can-eat buffets.
