Wintry Winter Storm Dec 7-10

Once again, the models completely botched the northward extent and intensity of the precipitation shield in an overrunning event in the SE US. NWP verification was probably made worse by the fact that most of us were in an incredible right entrance region of the upper level jet... Most of the lift here seemed to be generated by large-scale upper level divergence forced by this jet streak rather than broad isentropic upglide and concomitant warm air advection that we more often see in an event like this.

Even still I think we stand a better chance than we normally do because most of the lift is being generated by us being in the right place at the right time, namely this jet streak over New England instead of warm air advection riding over top of a antecedent cold dome we more commonly see w/ overrunning. We'll just have to wait and see
 
My sis just said it has cooled in her area of ATL (northern portion) from 39 to 36 over the last hour with rain increasing after having been dry. She had traveled from near the airport (southside), where it is was 38-39 about 45 minutes ago.
 
Not only that but the NAM sniffed out the deeper 500mb trough before the globals. Good call on the jet streak!!

Roads are beginning to get covered here. We probably have an inch right now and its hammering right now. This is AWESOME!
