We've wrapped up another wild weather day in the Pacific Northwest. A small tornado ripped through the city of Longview after the lunch hour on Thursday, skipping down 6 blocks and damaging some roofs and buildings before lifting back into the cloud deck. The National Weather Service sent out a team to survey the damage, and based on that, determined that it was indeed an EF-1 twister that swirled down Vandercook Way at 12:40 p.m. Things stayed unsettled from there, with a patch-work quilt of showers and sunbreaks around the region through the evening. Some of the breaks in the clouds lasted long enough to provide a fleeting glimpse of today's partial solar eclipse, and some of the showers were violent enough to drop hail or a bolt of lightning. Afternoon highs stayed in the upper 50s, which is typical for late October.
Late October? Can you believe we're nearing Halloween already? You might want to pick your pumpkin on Friday if you have the chance, because the dry window of opportunity to do so will slam shut pretty quickly. We'll start out Friday with just a few showers--the commute will be mainly dry, and lows will start in the 40s. Mainly cloudy skies stay with us through the afternoon, and temps will climb back into the 50s to near 60 degrees. There will be a few showers out there, but compared to the soggy deluge to come, it's probably your best shot at down-pour free gourd gathering before the weekend.
Another juicy, tightly wound up area of low pressure rides a strong jet toward the Northwest by Friday night. Winds will start to increase near the gaps in the Cascades after dark, and we may see some gusts upwards of 35 to 50 mph as the low approaches. The rain will increase late, especially after midnight.
Saturday will be soggy and gusty. The rain will be moderate at times through the morning, and winds around all of Western Washington will kick up between 30 and 45 mph, especially near the beaches and waterfront. Afternoon highs will stay in the 50s to near 60 again, but it will feel cooler thanks to the blustery conditions.
Sunday looks a bit calmer, but we'll still contend with lingering showers or even a stray thundershower. Temps will once again max out in the 50s.
Monday will again feature a drier break before another system pushes in by Monday night. Next week promises to be seasonably rainy at times, but so far the 30th is looking quieter. We'll see if we can keep things dry for trick-or-treating on Halloween night!
Have a good Friday,
