A Wet Evening For Some

September 24, 2008

Snapshot Quite a soaker for the east side of the metro area in the Cascade Foothills.  A band of rainfall has been lingering over the area for several hours.

Weak surface cold front appears to still be offshore, although it's awfully hard to find.

Post frontal day tomorrow looks really boring, then nicer weather Friday-Saturday.

Strong offshore flow and much warmer atmosphere prompted me to push forecast temps back up Sunday-Tuesday.  Models keep pushing back the westerly flow that punches into the Pacific Northwest next week.  The 00z GFS doesn't even have it until late Wednesday now.  The combination of a very warm atmosphere, southerly flow in the upper atmosphere, and offshore flow at the surface could get us surprisingly warm…September is going to end quite warm!  Mark Nelsen
