Modelology vs meteorology. 

Where exactly is the cold air coming from if it’s all above normal north of Tennessee? It has to travel from somewhere on the way down right? Cold air can’t come from the pacific at California’s latitude. Which would mean at minimum, near or slightly below normal temps north of TN as it travels down? 

Yeah. i don’t buy wall to wall torch up here either. Maybe it’s 80/20, 70/30 or whatever. But the main reason that it’s blue in the South while dark red over the Great lakes is due to the uniformity of the airmass. 40s is well above normal for the Grest Lakes, but below normal for Louisiana. 

 

 

 With the typical mean +PNA, even Canadian air that’s mild for them and the N US can come down rapidly enough to be BN once it gets to the south. Example: 20 F in MSP, which is AN for there in winter, can come down fast enough to limit modification and still bring BN 30F to the south. Some of the coldest winters in the SE were when it was mild in Canada. Canadian air with a straight shot down here is always cold for us. The coldest anomalies in a +PNA are often in the SE with New England to the Lakes often NN.

I agree, but verbatim the model run posted is not a classic +PNA/-EPO look that we tend to see in weaker Ninos. There may be periods of it, however which could be factored in the ensemble mean. I just wouldn’t take those blues in the South as “winter-like cold that supports snowfall most of the month.”

 Today’s OISST update (for June 3rd) doesn’t have the dramatic 0.09C rise of each of the last 2 days, but it still rose 0.04C to +1.229C.The implied RONI equivalent is ~+0.7C:

Winter storms in the South outside of the mountains are for the most part somewhat freaky events. Thus, due to the low frequency, our snowiest or iciest winters are often from mainly just one major (or series of) winter storms at most. Examples: late Jan of 1940, Feb of 1952, mid Feb of 1958, 12/31/1963, 2/9-10/1973, 3/1-2/1980, 3/24/1983, late Jan of 1987, 1/7-8/1988, mid Jan of 1992, the ice storm of late Jan 2005, and Dec of 2018. All of these were during El Niño and these were enough to make them wintry.

 So, El Nino’s on average produce for wintry precip despite often being Mei Lu from just one storm on the right track (usually Gulf to off SE Coast) at the right time (when cold enough air to the N/NW being tapped into enough).

Yep. And if you scroll thru the slp maps for each month, you can easily imagine at least one good hit down your way. January, and especially February, even show cold air/ridging pressing south along the Appalachians starting in Virginia.  Here's a link to December:

Can someone say +AO? (For the 3rd warm season in a row, since the Solar Max)

[Stormchaserchuck1]

May be one of the stronger -PNA's on record in the long range, near the 19-20th
