Cold spring weather systems eyeing Kitsap County next week

It’s been a busy weekend, with the Armed Forces Day Parade and Viking Fest going on among other things. The weather hasn’t been the most ideal, but it hasn’t been awful either. I think we got spoiled after our early May temperatures flirted with 90 degrees!

But such heat will be forcibly shoved in the back of our minds as a series of unseasonably cold weather systems march on through Western Washington, which will ultimately lead to some snow at the passes. More on that in a moment.

For now, expect mostly cloudy skies to continue through your Saturday. High temperatures will stay somewhere in the mid 50s, dropping off to the low and mid 40s overnight with only scattered showers around.

Sunday is turning out to be partly sunny with only a few early showers. Highs will be about 10 degrees warmer, rising to the mid 60s.

Although Monday appears partly sunny, dry, and mild with temperatures in the upper 60s to low 70s, we’re in for a big change starting Tuesday. Here’s a little visual explaining what is happening out there in the Pacific:

As you can see, the jet stream will be sagging far enough south to tap us in to cooler air from the north. This also translates to more showers and greater instability, which could produce a few thundershowers by midweek.

So, expect high temperatures to dip into the low to mid 50s on Tuesday and Wednesday with showers, a few sunbreaks, and a slight chance for some electrical activity. Of course, thundershowers are never an absolute around here, but we are entering that time of year when it becomes a very real possibility.

The mountain passes will also be getting in on the action, with periods of SNOW in the forecast for locations above 4,000 feet. It’s too early to tell how much snow will accumulate, but right now it doesn’t look like traffic over the passes Tuesday through Thursday of next week will be inhibited.

We rebound ever slightly for the end of next week, but if you’re looking for more 70 or 80 degree temperatures with sunshine, the rest of this month doesn’t look too promising. June is usually good to us in that department though 😉

Have a great weekend!
