Final September Rain Numbers

October 1, 2013

What a September!  Despite the government shutdown, which forced me to go search for the downtown rainfall record (Waaaah!) on my own, I’ve compiled the final rainfall numbers for our area.  All these locations had their wettest September on record:

That’s wet.  Can hardly believe the 3 day totals up around Mt. St. Helens…some spots saw over 15″ on the southwest flank of the mountain:

Where do we go from here?  Much drier, after tomorrow.  A weak and chilly system drops in over us Wednesday, then it’s on to dry weather for Thursday through Saturday.  Yesterday and this morning the GFS/ECMWF were at odds with each other for the weekend.  ECMWF crashing a wet system through here Sunday and the GFS weakening it severely.  I almost always go with the ECMWF…smart move this time around since now the 18z GFS is bringing the system through finally.  If so, we do get 3 whole dry days, a wet day, then back to drier weather next week again.

The overall message is that we’re back to normal now; some rain, some sun, some fog, and some dry weather for the first week or so of October.
