Pretty impressive to see that on the satellite picture like that. Probably starts to hit us late tonight. Any idea if that firehose lifts north or south and when? Could be some serious flooding.

6:45 am IR/Water Vapor. Atmospheric river inbound. Now that's a moisture plume!

Buckle up...it will get very wild for some on here: (7:04 says where the harsh winter will be)

If this progression occurred at Day 7-10 and not 13-16 maybe we would be getting somewhere as the main trough shifts back towards Siberia and ridge as well axis is west of ~140 W. The pattern has to flip at some point. This won't continue all winter. 12z GFS in 1 hour

NOAA: The evolution of Days 4-7 will be dependent on how the next few days play out, especially since these systems will likely see large amounts of latent heat release and convective influence from the southern CONUS. Eventually the baroclinic zone will depart in favor of a surge of colder air from Canada to start the New Year which would bring temperatures back toward normal (low 30s) and introduce snow chances once again to the forecast.
