Pattern The Great December Dump

[wxdaniel]

No, it doesn’t because there is no really significant warming in the stratosphere in the NH that would force a warm pattern. It actually works the other way around, a cold stratosphere entices the tropopause heights to rise >> warmer troposphere & vis versa with a warm stratosphere. I’m not sure why this is an argument because it shouldn’t be.

I’m not arguing the facts. I find it mere coincidental every time we have warmer tropopause heights the cold air moves over to the cooler side.

For one thing, there’s a massive difference in impacts from warm tropopause heights and a warm low-middle stratosphere and these temperature anomalies are often a reflection tropospheric wave activity rather than a forcing in the traditional sense

Nobody gonna mention the sneaky severe potential tomorrow?

I know it's the crazy morning run but gfs was close next week I'll be in Gatlinburg so book it! Its guna happen!

Upgraded to slight. If we get any breaks in the clouds and the sun comes out it could get real interesting

Dewpoints are in the mid to upper 60s in GA/SC/AL and near 70 in FL. This is almost summerlike and we can thank the SER for its part in this.

I missed this feeling of soup in the air

It looks like ATL, AHN, CSG, and GNV, among others, will end up with a record high minimum for today.

The euro ended so close to something

We need that low farther south then I’ll be interested .

Tornado watch out and this place is as quiet as a church mouse

 

[Myfrotho704_]

some damaging wind gusts/QLCS spin up tornadoes are possible, altho this is not impressive, and forcing is linear which mutes the tornado threat quite a bit, thermodynamics/low level instability and llvl lapse rates ain’t impressive, but SRH is definitely up there so like I said QLCS spinups is definitely possible

Honestly the euro verbatim would have probably been fun for a lot of NC as that low was pretty far south and cold filtering in

It is cold someplace. In fact, it's plenty of cold in many places. Just not here in this neck of the woods. If fortunes were reversed, a lot of other folks would be bemoaning the warmth. It's just a matter of wind and pattern. Nothing more and nothing less.

Sure is quiet in here considering there is a Tornado Warning for Starkville, MS.

Dec 2019 ended up 6.6 AN temps for Chattanooga.. 9 years running now with AN Decembers. 2010 was the last time below normal. Truly weird actually.
