Gonna get wet - from Cliff Mass (note: this was written Tuesday evening - tomorrow=today):
Heavy Rain and the Beginning of Autumn
Autumn began at 6:30 AM this morning and the atmosphere is clearly watching the calendar.
Tomorrow will bring the first of a series of wet weather systems, each associated with a potent atmospheric river, that will bring as much as TEN inches of precipitation to the northern Cascades and Olympics.
As a result, wildfire season in Washington State will be coming to an abrupt close.
Precipitation will be heaviest during two periods, one tomorrow and the other on Saturday, when atmospheric rivers--narrow currents of large water vapor values--will make landfall on our coast.
And we are then going to be hit by an atmospheric river. Not our usual Pineapple Express but a river none the less:
Even more impressive is the atmospheric river on Saturday morning.....wow...this is serious! Fascinating how moisture is concentrated into such narrow "atmospheric rivers". I will explain why in a future blog.
Ho. Li. Crap. Staring down the barrel of a deluge. The house is snug, good roof and got some nice raingear. Got firewood laid in for this winter and lots of food in storage. Life is good.
