Tonight’s weather radar pictures show a Big Blob of stormy something coming this way. But its true nature may not be revealed till after you tuck yourself beneath three layers of comforters (down from four last night, when Seattle set a for-this-date record low of 18 degrees). One thing seems to be for sure … by this time tomorrow night, we should be able to stop worrying about the weather for a while. Good thing, too, since three interesting events are happening in West Seattle tomorrow (Thursday) night — we’ll post about them first thing in the morning.
