Weather Detectives: Nabbing the Elusive “Gully Washer”!

“Did it or did it not rain on Thursday, June 11th?”

 This is the big question I had yesterday as I was going through old records from the Bremerton National Airport. On Thursday, June 11th the rain gauge read: 0.15”, which seemed preposterous to me considering the radar was quiet most of the day (or at least the hours I was awake) and it seemed unlikely the airport was the only place that got precip while not affecting anyone else.

But thanks to observant blog readers that live near the Airport we were able to put the pieces together and answer the question: what exactly happened Thursday the 11th? Many of you reported that there was a particularly strong thundershower around the Gold Mountain area that affected portions of Port Orchard and Dewatto. They referred to it as a gully washer, which is a heavy downpour of rain that typically has a lot of runoff associated with it. They aren’t common in this area believe it or not (which explains why this is the first time I have heard the term used) but they can and do happen.

So I’m thinking that could very well be the culprit…not a mist, but a gully washer that, as one of the commentors noticed, “puff[ed] itself up in a big hurry, seemingly from nowhere”. Thanks for being weather detectives for me! I do realize the Airport creates it’s own weather but I also know that information can be inaccurately reported. That’s why I love the public’s help!

So it appears, for at least a small portion of Kitsap, the 27 day dry weather streak has ended, but for others it is still going but could end soon as a widespread front is moving in that could squash any “hopes” of making the record books. You’ll notice the clouds continue to increase this evening ahead of the front and sprinkles will likely be the biggest event that will come out of the front.

The next shot of rain could affect the area in the afternoon as a convergence zone forms. These zones typically only affect the northern and eastern zones of Kitsap county, but just be aware that it could get a little damp tomorrow. Regardless, it’s looking kinda cloudy and cool with highs in the mid to upper 60s.

We dry out again Thursday through Saturday before more showers and cooler temperatures creep back into the forecast.

Remember Kitsap…if you experience any more gully washers let me know! 🙂
