Severe Weather / Re: December 10th-11th Storminess

More about the severe weather potential.
The overall setup is that of concern.  We have a sub-1000 mb low tracking across where Missouri/Iowa/Illinois meet, which is actually a classic track for severe weather events for our region.  That will provide us suitable wind energy and wind shear.  It also appears that we will have an airmass that is unstable enough.
This does lead to a solid chance for severe storms Friday through Friday Night.  With that being said there are a few things to be decided.
- Will there be enough of a lifting mechanism out ahead of the front to create supercells.  If so then the severe weather threat and especially tornado threat jumps up quite a bit.
- What will the storm mode be ahead of the front.  A solid line will lead to more of a damaging wind event whereas a broken line will have the potential for embedded supercells aka a better tornado threat. 
- Will there be any messy convection out ahead of the system?  Which could limit the severe threat at least somewhat.
Still, we need to watch Friday afternoon through the wee-morning hours of Saturday as the ceiling for this event is fairly high

I just want Wet bulbs below 20F and Ill be happy. Ill produce the moisture, I just need mother nature to produce the cold. On a good note there is a nice atmospheric river event shaping up for the Sierras. Much needed snowfall in all the western states aside from Washington. Ill give up a cold December in Nashville to put down base out west.

MJO does appear to go into Phase 7 and potentially 8 later on this month.  If that is true then we should finally see a pattern that is more winter-like by sometime in the New Year/early Jan timeframe.

84-85    ::fingerscrossed::   ;)   ;D

There's also some indication the AO and NAO are going to go neg. and the PNA will trend toward positive. That would be good.

There is a Level 2 out of 5 risk for West/Middle TN for Friday/Friday evening.  Details about low-level shear and storm mode remain but the potential is there for an active severe weather day with all hazards on the table.
