Multiple tornado warnings right now down around Columbus.

Tornado warning here in Newnan now. Impreseive rotation moving right over the city.

Hearing sirens too.

FYI we have a Delta inland thread in the tropical section. Didn't want you to miss out on other posts for your area

Thanks. I didn't know about that thread.

Thanks. I didn't know about that thread.

No worries.

Strong La Nina (-1.5 or colder peak) winters per the linked table: average 2-2.5 F warmer than normal. No big deal. I'll enjoy the winter just because it is the winter and way colder than any other season, the most enjoyable season with plenty of wild changes and many pleasant days even in a warmer than normal winter. Also, some of you may even luck out and get a big winter storm as more often than not there will be one somewhere at some point, especially in NC/TN:

I can’t help but notice when looking at the winters you mention featuring a strong La Niña what also happened in those following springs. Namely, 1974, 1999, 2008, and 2011 stick out as some fairly active severe weather seasons, or at least had some fairly significant events. Interesting to see how these have correlated previously.

Each one. Those four years mentioned there had a classic tornado outbreak associated with it

Any thoughts for SVR on the pre-thanksgiving system? Spann has mentioned it as well as some local guys in W TN.

Probably too early to tell much right now. Instability is a question mark.

FROM THE BMX NWS

Concerning the storm chances for late Tuesday into Wednesday, the
trough will move from the Central Plains northeast into the Ohio
River Valley with a surface low progged to track from the Central
Plains northeast into the Ohio River Valley. The surface low
proximity and track will create favorable wind shear and helicity
parameters for active weather and the presence of a low-level jet
is well-depicted by most modeling. However, available low-level
instability is lacking. Agree fully with the midnight shift that
the warm sector appears to be fairly narrow with limited airmass
recovery time from the previous frontal passage. We will continue
to monitor modeling trends and continue to evaluate convective
parameters for this system.
