I know everyone is focused on the "storm" on Presidents Day...if you had not noticed the Euro weeklies, you should take a look...Winter will be back potentially with a vengeance along about the 25th or so....another potentially prolonged cold period into the first half of March per the model...Don't wear yourself out too much yet!

Thanks Bob, always appreciate your input.

 

I have been noticing most modeling ensemble packages being INSISTENT on building a massive ridge out west clear to the pole.  Do you think we finally see a period of blocking in the Atlantic or is that going to continue to be like finding a unicorn?

Mr. Bob, bringing the cold hammer this morning.  For those new to the board, Mr. Bob is about as good as it gets and does not hype.  Great met.

Yes, that looks great, although, I am getting really close to having Spring fever, especially after whatever happens Sunday night into Monday!

Back to my post on #741 the euro continues to build a ridge building into East Asia but is faster than the original map on todays 12z.This map is off the 850mb coming up but the question now is if there is moisture returns and where everything is placed,but a severe threat still seems plausible.

Jax, hoping we don't get severe!  Ha!  I know you enjoy it.  And think about this, storms just a while back and now snow.  Thunder in the mountains, and it snows w/in three weeks.  Hey, two more days in the avatar.  Manning still looking good...

Our next potentially wintery system seems to be brewing around day 8-9. The GFS/Euro/CMC are all showing some type of southern low track.

 

The GFS looks like it's going to build a winner right here with the big 1042 H dropping in with -20 degree temps and a low over Texas.

Until it gets really really weird 18 hours after this.

KTRI has now recorded just under 17" of snow for the winter.  That is far past anything I expected during a strong Nino.  I suspect the weak solar cycle has something to do w/ this.  In the past decade, we even have had a snow winter during a strong Nina if I remember correctly.  Next winter, the odds that the Nino will be weakly on either side of neutral might be increasing.  Now, having lived in Knoxville during the last strong Nino...I can tell you it is tough down there to get it to snow.  I live in Kingsport now and latitude makes a huge difference.  But February is a great time for the central TN Valley to score w/ snow, so that is in their favor.  Plus, Ninos in general have winters that are back loaded...

It's also been a great winter for southern Kentucky, and even parts of middle Tennessee.   The last two years have been good to the central valley of east TN.  So, this may be our year that's a dud.

GFS is still showing a good look. LP taking a Miller A track and a 1033 high in the plains dropping south and another 1038 high over upstate New York. 

 

It doesn't show much of anything for here but that pattern would produce here.

The euro control at 12z has a far east TN and southern apps snow (8-10 inches) between 8.5 and 9.5 days.  I counted 10/51 members that had over 6 inches in some part of the state.  Fairly robust signal for the potential that period might hold.  Carry on.......

Each winter of last several, aside from 11/12, have had some good snows. I tend to believe like JB that we are in a period of colder snowier times. At the end of the Dalton Minimum we had things like Washington crossing Potomac's ice clogged water, while the founders of Nashville walked across the Cumberland River. I hate to think what would happen if we saw those conditions in modern times.

Euro has a Carolina crusher on that day 8 storm. Which isn't far off where we want it to be at this range. Every storm this year has came north/west vs their early model runs.

6z GFS has potential as well. Yep. We want any cyclogenesis way to our southeast in the LR. The Euro weeklies show what I presume to be a parade of storms across the southeast. Not saying they are winter storms, but seemed to have plenty of energy.
