Snoqualmie Weather

After 9.1" of torrential rain fell over the last 3 days in the mountains (as observed at Snotel-Olallie Meadow near Snoqualmie Pass) led to major flooding in Snoqualmie Valley,  how did  river flow end up ranking historically? Today's peak flow, measured in cubic feet per second (cfs), near Snoqualmie Falls ranked 14th all-time (based on historical NWS data back to 1959).

Right on schedule for this time of year.   As is often said, October comes in like a lamb, goes out like a lion. Yesterday (October15 th ) marked the last day for the next six months the average high temperature exceeds 60°. This is based on 75 years of weather data taken at Snoqualmie Falls (Western Regional Climate Center). Here are the seasonal breakpoints: Even though wind advisories are not currently issued for the East Puget Sound Foothills this week, I am watching one higher resolution model (ECMWF or Euro) that shows gusty southerly winds out here peaking in the 40-50 mph range for Thursday evening, and again during the day on Saturday, as well as potentially Monday morning.   With a lot of leaves still on trees it wouldn’t take super strong winds to snap branches and potentially make a mess of an otherwise just soggy situation.

The warm blob of water off our coast, that threatened a snow deprived winter for the mountains, has weakened significantly since late summer. Our chances for a normal-ish winter have increased!
