AMS Meeting Thursday

May 12, 2009

We have an Oregon Chapter AMS meeting this Thursday.  Anyone is welcome for good food and weather chat.  Dinner generally seems to cost $10-$20 if my memory is correct.  Remember that you don’t actually have to eat, you could just come and have a drink, socialize, and steal someone else’s cup of spumoni ice cream…just not mine.  Actually I don’t think I’ll make it to this meeting since it’s so far from work, so grab some from someone else.

TONIGHT’S WEATHER:  Easy forecast through about Sunday, but the last two days of the extended forecast are messy.  Warm up still looks great Friday through Sunday, but the last few runs of the GFS have shown a deep and fast moving upper-level trough swinging through the Pacific Northwest Monday.  Meanwhile, the 12z ECMWF went the other direction.  It has the energy digging far offshore pumping up a hot ridge over us.  It doesn’t get much more extreme than this:  00z GFS has 850 mb temp Monday afternoon over PDX of -1!  The 12z ECMWF has about 21!  So…it’s either going to be 93 or 60 for a high in Portland on Monday!  Now that’s some fun forecasting.  We decided to leave the two 85 degree temps in the forecast until things flesh out tomorrow.  I have a gut feeling that tonight’s 00z ECMWF will make a dramatic change towards the GFS solution.  I do notice that both models keep us relatively dry next week.

I’ve turned off the “Gravatars” (the pictures) in the comments for now, let me know (in the comments) what you think.  Seems like only some of us were using them and maybe a few were annoyed by them.
