Mesoscale models show today's pattern getting stuck like a rudder over the next 24 hours until the trough axis moves through midday tomorrow. Means lots of CZ related rain continuing in the Everett area overnight, switching to the Seattle area tomorrow evening. When that switch does happen it will occur during peak daytime heating and come through like a squall line. I'd place decent bets on some thunder in North Seattle tomorrow.
Could get more rain tomorrow night than we will Friday night, if luck is on our side.
My sister's MIL in DFW posted pictures of snapped trees on their property and fallen trees covering their pool. Sister and her husband plus everyone on his side are all safe but that was much more real than they are used to.
