9/6/2013 7:30 AM 1.73 M M M M Holy wow, what a storm last night!! This is the first time in over 3 years as a CoCoRaHS observer that the inner cylinder of my rain gauge has overflowed into the outer cylinder in a 24 hr period. Storm began about 10:50 PM last night, with wind ramping up to 15 mph sustained and 30 mph gusts. Got ~0.7" just in the first hour, according to our Davis wx station. Lots and lots of cloud-to-cloud lightning all across the sky in every direction, which was unusual and fascinating. Winds calmed down to 5-10 mph by ~12:15. Another heavy downpour b/w 1:30-2AM; storm over by 4:30 AM. Total rain registered by the Davis Vantage II wx station (just uphill from the CoCoRaHS rain gauge) was 1.75" over the same period. And North Cascades highway closed before 2 AM, again due to mud slides near Granite Creek. WILD! Great to experience...from inside!
9/7/2013 8:00 AM 0.61 M M M M More and more rain! It's welcome. River hydrographs are shooting up, and lots of mud. Rain gauge 24-hr amount agrees with Davis wx station; 0.23" just since midnight. Still raining now (8 AM).

9/23/2013 7:00 AM 0.01 M M M M Yesterday afternoon's frontal passage didn't bring us much rain at the house, but it left a healthy blanket of new snow in the higher North Cascade peaks-- the first of the season! These peaks have been devoid of snow for several weeks to more than a month. New snow on Mt. Gardner, the Pasayten, and some in the Sawtooths. Not as low down as Goat Peak, however. Pretty good welcome to the first day of Fall!

And sustained winds over 20 mps with gusts over 40 mph. Neighbors reported intense, rapid lightning all across the sky. Total amount of rain in the CoCoRaHS rain gauge for this multi-day accumulation period matched what was logged by the Davis wx station.
