As high pressure rebuilds up into Alaska and Northwest Canada, the arctic hound has returned to the Lower 48 and boy what a 1-3 weeks we have with not just bitter late season cold but California gold! Big rains which dive all the way into the LA and San Diego areas that is late week into the weekend.
Arctic air is rotating back into the Lower 48 on the western and southern flank of the Hudson Bay vortex which is getting pushed south once again. We have a strong undercutting southern branch jet which will present arid California with a much needed drenching. The latest models support as much as 5 inches of rain around the Los Angeles basin alone with much of that falling between Thursday and Sunday. These disturbances cross the Rockies and with warm meeting cold on the plains, look out for anything between a coating to 3″ or a more significant 6 incher across the TN-OH valleys into the Mid-Atlantic and Northeast.

Modelling has turned around on the big midweek snowstorm for the Mid-Atlantic and Northeast but there are multiple opportunities with this pattern for snow events which lay down that carpet of white once again.
Here’s the latest CFSv2 showing the hammer coming back down and heights really build up over Alaska again.
The CFSv2 goes to the extreme for cold week 3 (March 10-16)

The cold gets bad by late this week, check out these temperatures Friday morning off the ECMWF.
While this week as a whole is cold from North Dakota to western Pennsylvania, the latter part of the week appears coldest. With this latest outbreak, I’m expecting at least -15 in Minneapolis, -7 Chicago, 0 Pittsburgh and possibly 10 in New York.
Here’s the latest ECMWF snow chart. Nothing particularly impressive through the next 5-7 days but into next week and things may get interesting in terms of bigger snows over the East.

Notice the big increase in snow by 192! Model’s sniffing out a big snowstorm!
But.. going by various models including the GFS, ECMWF and CFS, we have plenty more cold to follow after this week..
As for Minneapolis, this winter according to the Twin Cities NWS is the 11th coldest and when including this week’s cold, it’s likely to enter the top 10 list which records go back to 1899.
This morning marked day 43 below zero and 46 at or below zero. Couple another 7 straight nights below zero and we could be talking number 4 or even 3 for most sub 0 nights in a winter season.
This pattern is terrific for drought stricken California. A real soaking is on the way. See video for details.
Here’s the latest QPF through the next 7 days. Note it has 4-5 inches of rain around the LA Basin.
