ECMWF Weekly Maps: Warm Weather Is Toast?

September 14, 2015

4pm Monday…

Last night’s run of the ECMWF and its ensembles out to 32 days shows a cool upper-level trough lingering overhead the rest of the month.  It’s looking like September 2015 may be the first month with below normal temps since last November!  This will also finish off the fire season as well if the trend continues to be cooler/wetter than normal.  That said, after the hottest summer on record around here it’s time to even things out a bit.  Here are weeks 1-3:

500za_week3_bg_NA

And week 4 which looks a bit more seasonal for early-mid October:
