A Warm Month

January 19, 2010

This was a great day to get outside.  I actually took a bike ride midday under the swaying trees…a bit scary at times up in the Cascade foothills today with gusty downslope winds.  But with temperatures up near 60 degrees it felt like March.  It has been a very mild month.  I see Salem is running +6.8 degrees from average and Portland over 5 degrees so far.  And there’s no big change on the way.  No model shows a blast of cold air or snow to low elevations in the next 7+ days.  Do you realize neither Portland or Salem have even seen a frost this month so far?  Strange…I think it was 2006 when we went without a frost at PDX the whole month.  But as we know…a lot could change in the next 10 days.

In the short term, the east wind backed off this afternoon after a wave went through, but approaching low pressure system #3 this week should really tighten up the cross-Cascade gradient by midday tomorrow.  So I think it’ll be a windy and mild afternoon again on Wednesday.  Some rain may fall at some point tomorrow, but it won’t be much.  That deep low makes a very slow move up the Coast late tomorrow night and Thursday, negating any good chance for strong south wind in the Valley.  I’m sure it’ll turn windy at the beaches, but other than that this one could be a snoozer inland with no significant wind OR rain.  I really like the sub 980 low that moves into SE Oregon on Friday…you don’t see that very often!  Lots of snow in the Great Basin coming up…
