ECMWF Monthly Run

September 21, 2015

You know the drill; hardcore weather geeks only beyond this point on this post…

Not TOO much different than what it was seeing a week ago.  Hints that the upper-level trough that has been nearby much of this month will shift a bit farther west around the 2nd week of October.  Not much change in the next two weeks though.  Looks like our cooler than normal September will continue the next 10 days.

New info from here on out…looks like ensemble mean for precipitation (through the 18th of October) is around 2″, about 1″ on the control run…so a bit drier than normal and no obvious sign the wet season is about to begin.
