ECMWF Monthly Run

October 3, 2014

It’s a day old now, but ECMWF 32 day run (along with its ensembles) looks like this:

500za_week1_bg_NA 500za_week2_bg_NA

After the middle of the month it allows more somewhat splitty troughs to move through with the ridging gone.

500za_week3_bg_NA 500za_week4_bg_NA

Interesting to note the 32 day control run (surface map) shows wetter conditions to the south with a splitting trough.  Rain for California but just cooler and a little wetter for us.   I hope that’s not a sign of the winter season to come!
