IMO, the following week looks ripe for "Ridge Riders" as the NW Flow aloft can really blow up storms on the leeward side of the CO Rockies. This pattern is prime for developing monstrous storms.
SEA is .98 now since yesterday morning. ECMWF yesterday morning showed SEA getting about an inch through 5 a.m. this morning so it was right on target.
It also shows about another .45 through tomorrow afternoon so it's likely SEA will be close to normal rainfall for all of June by the 4th day of the month.
