It doesn't get good until hour 330...LOL.    What is wrong with us.

It's nice to see our local offices mentioning what's been in LaLa land for weeks now.  

 

 Beginning of a colder pattern change late in the period

The entire long wave trough will lift out of the region on Sunday,
cooling things down some. The cooldown for Sunday and Monday does
not look to be too significant for this time of the year, except
coming off of the 50 degree temps for the weekend. This is because
we will be in between the two branches of the upper jet.

We are looking at a more significant cool down that may begin as
early as next Tuesday, and more likely just beyond. This is
something that the long term model ensembles have been showing for
quite a while. We will see another active southern stream system
come out of the desert SW, and a stronger northern stream system
diving in from the NW.

Lots of details to be ironed out yet how the two branches will
interact and phase with each other. The net result though looks to
be a colder pattern as we enter the New Year.
