.NOW… AT 1045 AM…A BAND OF THUNDERSTORMS STRETCHED ACROSS THE SEATTLE METRO AREA FROM NEAR NEWCASTLE…THROUGH SEATTLE TO POULSBO AND ON TO QUILCENE. THE BAND OF STORMS IS SLOWLY SPREADING SOUTHWEST NEAR 5 MPH. THROUGH 1 PM…THE MOST CONCENTRATED AREA OF THUNDERSTORMS WILL SPREAD SOUTHWEST TOWARD BLACK DIAMOND…DES MOINES… BREMERTON AND SEABECK. THUNDERSTORMS WILL BE CAPABLE OF PRODUCING SMALL HAIL…INTENSE RAINFALL AND DANGEROUS CLOUD-TO-GROUND LIGHTNING. IF YOU HEAR THUNDER…GO INDOORS.
Well, hello Friday the 13th! How appropriate that we’d be talking about thunderstorms on a day like this 😉 Did you notice it feels a little more humid this morning than usual? The weather lately has been more reminiscent of Kansas City, Missouri than Seattle, Washington, especially when seeing the humidity at 85%!
Like many of you, I was up last night tracking the brief hail/rain shower than moved through the central Kitsap area which also included thunder and lightning at times. Now it appears we could be under the threat for more of these storms over the next couple days as the atmosphere remains rather unstable and easterly flow pushes a lot of these storms from the mountains into the lowlands.
Currently we are under cloudy skies as a result of the marine layer that moved in overnight, but the issue here is what’s ABOVE the marine layer. The unstable airmass aloft combined with persistent easterly flow will keep the threat for thundershowers, hail and periods of lightning in the forecast through Sunday night.
Feel free to help in tracking the storm by using the comment section below to describe what’s happening in your area! More updates this afternoon…
