Warm front moving east out of the Northern Plains on Monday could help generate a few showers and thunderstorms in the Northland thanks to increasing amounts of mostly elevated CAPE (instability)

Kind of an unusual spot to see a Severe Thunderstorm Watch in late May, but portions of Washington and Oregon are under a Severe Thunderstorm Watch through early this Saturday evening.

The Northland is currently under a pleasantly cool NW flow aloft, but by Monday will begin to get more of a WNW flow aloft across our area as the ridge over the southwest US builds further N-NE next week.

Temperatures this Saturday afternoon range from around 30 degrees on the east shores of Hudson Bay Canada to 105 degrees at Phoenix, Arizona.

There are signs showing up in the long range computer models for a wetter pattern to setup across the upper Midwest starting ~June 6th, will see if this actually does happen though. A dry pattern like much of the Northland has been in for months can be hard to break out of.

The forecast below shows total precipitation amounts through June 14th, 2020.
