southeast ridge has been trending stronger, but after is interesting, do we extend pacific jet to a area that drops the hammer for fall standards, or do we overextend the pacific jet and go from warm, quick cold, back to zonal warm. One thing is for sure, do to the strong -EPO, there’s gonna be a large reservoir of cold in Canada.

Yeah but one thing we have learned , snowpack don’t mean squat to get cold down to the southeast …. I used think that it does .
 
The one thing about droughts is they usually don't just go away quietly. More often than not they usually break with some rope of high impact event. Whether it be severe thunderstorms, flooding, tropical system, or a sudden change to extreme cold. Something to keep in mind.

It's possible out here this coming week with the hurricane remnants and the cold front and I've definitely seen it before
