Cold Weekend

March 30, 2007

A brief post tonight since I’m a bit behind, plus it’s 11:05pm on a Friday night.

Models are hanging onto a very cold airmass moving in over the Northwest tomorrow evening.  Our RPM model shows snow supposedly possible down to 1000′ Sunday morning.  There is no meteorological reason that couldn’t happen with 850mb temps down to -7 or -8 deg.C.  BUT, showers look awfully weak until we get to the midday and afternoon heating Sunday.  At that time the snow level would be up to 2000′ or so.  So a very chilly day coming up for Sunday with scattered showers and sunbreaks, and the foothills could easily see a late-season dusting of snow…maybe an inch or two above 1,500′.

Warming next week is still on track, although 00z GFS wouldn’t support temps much above 65 degrees…Enjoy the chilly weekend!  Mark
