9 -19 Weather Forecast (Early Edition)

Good Evening.  A couple of big changes coming in the upcoming weather.  These a still a ways off, but noteworthy right now.  First, the Jet Stream ten days from now.  I know it's a long way away, but take a look:

 

10 Day forecast of 300 mb winds and heights from the GFS model

 

 

Remember that cut-off Low in the Jet Stream from earlier this year, that gave the SW quite a bit of rain?  Well, this one is bigger, and could be soaker.  Again, this is ten days from now:

 

10 Day forecast of surface pressure and precipitation amounts from the GFS model

 

 

Once that cut-off Low breaks off, it depends on where it goes and how long it sticks around.  The one last earlier this year, stuck around 4 - 5 days, and was the beginning of the drought buster in the plains.  My guess is this one will follow a similar track - over KS, NE, OK, and dip SE into AR before probably getting reincorporated into the Jet.

 

Also, a week away, for Washington State and Oregon, finally, a shot at some rainfall coming in:

A low is finally able to dip down low enough, and sneak past the High in the Pacific to deliver some much needed rainfall.  Again, still a week away, a lot can change - stay tuned.

Thanks Jen! I hope it isn't too late...I heard at the local coffee shop that the fish have given up and grown legs.

Hi Jenny

Just to update you on the cold spell in Ontario.

went to 3C last night here and from reports I have heard that seems quite a widespread area.

Some reports of frost on rooves but no evidence of any plant damage.

Saved with a nice breeze probably.

 

Thanks for your reports.
