Ya this is very similar to late October into early November when my area finally saw some much needed moisture at the time.
Gary lezak is expecting some flooding in the plains.
Yes, yesterday was more showery and hit or miss rather than what looks like a more straitform widespread type of deal. Looks like somewhere right between SEA and PDX will be in the bullseye.
Sometimes these showery cold core precip type of days can be pretty widespread and not so spotty but yesterday it was not very great coverage unfortunately.
Good news is that as you noted earlier, it looks like the next system will provide much more widespread, even totals for western WA/OR. I bet most places end up in the .5-1" range for the month by end of day Tuesday.
