Today I am excited to announce that my personal blog will be transitioning to a new weather blog -- The Convergence Zone. To begin on the first day of Water Year 2021, my colleague Ana Ordoñez wrote a nice summary of water year 2020 + a preview of 2021:
Interesting forecast ahead, many in western WA could see first snowflakes of the season on Sat AM or more likely Mon AM. Best chance will be above 1,000 ft elevation but can’t rule out the lowlands (especially N of Seattle) just yet. Low impact event w/ any accumulation on grass.
A rough rule of thumb in Seattle is that lowland snow is possible when the 850 hPa temperature is -6 °C or lower. The likelihood of entering the "lowland snow zone" in the next 7-10 days is slim to none (according to the ECMWF ensemble).
Some personal news — today is my last day as a postdoc at WSU. My next role is with the weather solutions group at @Verisk. I’m excited to begin a new chapter with new challenges.
And no, I’m not moving anywhere, thanks to remote work I’m not even changing offices :)
Strong, multi-model ensemble agreement that very dry & anomalously warm pattern will continue across US West for next 10+ days. Hints of colder/wetter shift toward mid-Dec, but nothing convincing yet. Some places (esp. in CO) will experience latest snowfall on record. #CAwx#COwx
Seattle picked up another half inch of rain last night. We need 1.50" to reach the fall rainfall record, which will be eclipsed this weekend.
1 - 2006 - 18.61"
2 - 2016 - 17.58"
3 - 1950 - 17.49"
4 - 2021 - 17.11"
5 - 1955 - 17.08"
Another #AtmosphericRiver is aimed at British Columbia Canada & western Washington state today. Per the @NWSSeattle forecast discussion: "at least 3 distinct atmospheric river events" will impact the region this week, raising concerns for #flooding. #WAwx
