One Post This Week

October 23, 2006

I’m taking time off Tuesday-Sunday and won’t be back until next Monday, so it’s possible there won’t be any posts the rest of the week.  That’s unless Drew decides to check in Wednesday, Thursday, or Friday.

Nice little cold front advancing towards the coastline at a pretty good clip this evening.  Should be over the metro area by 5am at the latest.  As someone on the earlier comments noted, it doesn’t have much moisture with it and the high clouds have pulled away from the low-level front.  So total rain here in the Western Valleys will likely only be .25-.50".  The coldest air of the season is following though.  An 850mb temp just below zero by Wednesday AM could bring snow down to just under 4000′, but there will be very little precip by that time.  At best expect a light dusting in the Cascades. 

A somewhat flat ridge follows Wednesday-Sunday for mainly dry weather again.  I’m assuming we get some southerly surface wind Friday or Saturday to push temperatures back up to or near 70 degrees. 

Long range models continue to be all over the place with very little continuity between models and even within model runs themselves.  Some show troughing moving inland Monday and beyond, but others split the trough and keep most offshore.  Roll the dice!…Mark

Update – 7:30pm.  Upon closer inspection of models, including our own RPM model here…looks more like .10" west metro to .25" east metro with the incoming cold front…a pretty dry one.  Hope it’s not a sign of the winter to come!
