Weather Pattern Clues through the End of October

September 28, 2012; 2:32 PM ET

This is my latest interpretation of the ECMWF weekly long-range model output. The forecast now goes out through most of October.

Below is a graphic that we drew up yesterday showing one of the atmospheric teleconnections that we look at. This particular teleconnection is that when we see a typhoon recurving northeastward near Japan we usually see a trough (dip in the jet stream) pushing into the central or eastern U.S. with colder air about 10 to 14 days later.

As you can see, the first ECMWF model panel pretty much supports that idea.......
