This is the rare situation where we head to a location when they are about to see a round of nasty weather. Usually, we get there when it’s just finished.
At 954PM, PT, Olympia was reporting a temperature of 26 degrees with mostly cloudy skies. The first round of nasty weather with the latest system is through as surface low pressure has sunk from western Washington to northern California where it will melt away in the presence of a strong upper level ridge. The pattern is still quite active as the polar jet is encouraging progressive activity from the typical low in the Gulf of Alaska.
The next round is coming tomorrow evening, with the development of a small area of low pressure near Vancouver Island. That low will start bringing precipitation to the Puget Sound area while it is reinforced by a trough diving southeast from the Gulf of Alaska. Surface low pressure will deepen just off shore through the day, pumping more and more moisture into the area. Precipitation will be at its heaviest on Monday night.
