Somewhat Wet Weekend

May 18, 2007

SnapshotA tough weekend forecast tonight…again.  Looks like the main cold pool stays off to the northwest of us tomorrow.  If so, once the steady rain this evening moves out of the area we should be mainly dry until Sunday.  But scattered, cold showers return on Sunday.  850mb. temps drop to around zero Sunday, which is pretty chilly this time of year.  As a result we’ll stay in the 50’s most, if not all, of the day Sunday.
00z runs of GFS and Canadian confirm flatter ridging for next week.  Still mainly, or all, dry from Monday through Friday, but not too warm…maybe only into the 70’s.  I have camping reservations next Friday and Saturday night, so it had better not turn cold and rainy in the Cascades…or I’m coming home…In the very near term, nice line of thunderstorms moving through southcentral Washington at 10:50pm.  Lots of lightning strikes just north of Hermiston and Umatilla…Mark
