Another Stormy Weekend Ahead

January 26, 2006

A break this evening as cold & unstable air moves in behind today’s cold front.  Snow fell in the Coast Range down below 1000′ briefly this evening.  KPTV Tower temps up to 1900′ show temps remaining above 34 degrees, so snow probably won’t much below 2000′ overnight.

The long conveyor belt of subtropical moisture is poised to return to the Northwest this weekend.  A "cold" storm moves through Friday night/Saturday and then a very strong warm front/cold front couplet Saturday night-Sunday night.  The first may produce almost an inch of precip in the city, while the 2nd could easily be a 2" storm.  Keep in mind we’ve now had 8" in Portland so far this month.  We could be pushing 11" by the time January ends (Tuesday night).

Very cold weather in Alaska, but that’s mainly because the Jet Stream is depressed so far to the south in the North Pacific.  So the cold air just sits there and deepens.  No model shows that cold air moving south in the next 7 days, not even into the Central or Eastern U.S.  So our "La Nina" winter appears to continue…our wettest since the late 1990’s.
