No specific threat being outlined by SPC just yet but that could change over the next few days. Pretty potent trough looks to be moving through during the middle of next week. This has every opportunity to be the first legitimate threat of the severe weather season.
 
Gfs looks nice for a QLCS with a + tilted trof 332FFD60-6D8D-4385-BD10-C719B60BD6CA.png8388F0A2-A4C2-4347-8C87-B422CA3A0EC7.pngBF819744-1F1E-4F45-AED7-17A447ED8322.pngeuro looked interesting as it appeared it I went negative before IT headed north and after that another SER pump/flex occurred 6E0AAF5F-8512-4BF6-BFDC-FCEA682679C1.png
 
New models runs are looking more bullish on severe weather, and have popped a nice ULL that nuetrally tilts/ even goes slightly negative tilt before it ejects, with a nice SER flex, and surface low in the SE, this may be a big one 46D214B5-E2AB-4545-80AF-121217E2AE1E.pngE858AAAE-8B8D-402A-8BD3-3F9CBC29A342.png5BA5421D-AFFA-4C7D-A379-62A10EE5CB27.pngDF507207-0365-41BF-9142-1075EA02D3C7.jpeg

Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0155 AM CST Thu Feb 27 2020

Valid 011200Z - 061200Z

...DISCUSSION...
Medium-range guidance continues to come into better agreement
regarding the eastward ejection of an upper trough/low from the
Southwest and northern Mexico across the southern/central Plains
from Day 4/Sunday through Day 6/Tuesday. Low-level moisture will
continue to advect northward across the southern Plains and lower MS
Valley in this time frame. The past several runs of the
deterministic ECMWF have been relatively consistent in the timing
and amplitude of the eastward ejection of the upper trough/low.

The potential for substantial low-level moisture return across parts
of east TX into the ArkLaMiss by Day 6/Tuesday has increased. Low
and mid-level flow are also forecast to markedly strengthen across
these areas, particularly Tuesday evening into early Wednesday
morning. With strong forcing for ascent preceding the upper
trough/low, a surface low should deepen as it develops northeastward
from portions of east TX into the vicinity of the Mid-South. A
trailing cold front should also shift eastward across TX into parts
of the lower MS Valley by the end of the Day 6/Tuesday period (early
Wednesday morning).

A thermodynamic and kinematic parameter space favorable for the
formation and maintenance of organized severe thunderstorms will
probably exist over these areas from Tuesday evening though early
Wednesday morning. Storms could form both along and ahead of the
eastward-moving cold front, with all severe hazards possible.
Therefore, a 15% severe delineation has been introduced for Day
6/Tuesday. There is some uncertainty with how far east the threat
will extend into MS late Tuesday night, and adjustments to this 15%
area are likely.

Uncertainty in the placement of both the upper trough/low and
related surface low increases into Day 7/Wednesday. At least some
severe threat may continue across parts of the Southeast (mainly
AL/GA vicinity), but low-level moisture should gradually decrease
with eastward extent. 15% severe probabilities may be needed in a
later outlook issuance over parts of the Southeast on Day
7/Wednesday once the synoptic-scale evolution becomes a bit clearer.

This is different setup in some aspects. More west to east severe warm sector thump potential. Compared to last event started as wintry mix in mtns north into Virginia blue ridge with strong backdoor cold front with a tornado in Charlotte. GFS shows it ending as snow for mtns. Bit different thermals to work with all around initially and to end. some severe wind gusts could occur but I’m nothing thinking tornadoes just yet.

QLCS is favored with its typical hazards with this look, While tornado threat is low, that LLVL jet is very strong
 
Any chance this low pressure system tracks farther south and is deeper. And hopefully gives alabama a decent snow lol???
 
Threat of severe weather is going right down the drain just like this winter.

Yes, but ofc, the GFS is trying to shift the axis of heavy rain right back into Northern Alabama and GA who don't really need more of it right now. Looks like the threat of flooding is right back on the table and here I thought GA would finally get a real break.

Yes and keeps moving south, and increasing.. Some are up to 6-7" across northMetro ATL.. Not goodat all !
 
suprised there’s no mention about this but the HRRR fires up supercells tommorow, HRRR/RAP have solid supercell composite numbers, I see that as opportunity for a good photo 8B645567-CF42-4930-8873-04A8B0D9FE01.jpeg3A993BC2-1EEE-4D3B-A295-1159BA6ECAFD.png
 
Now that is impressive. Screaming supercells. Deep moisture and good 0-3km cape to boot.

Yeah, Streamwise vorticity central with that hodo, right over MBY, might just begin chasing tommorow instead of April/May if I have to.....

Don’t get blown away, low lcls and the more I look at it, that may be the nastiest sounding so far this year. Now I know you know this but it’s worth saying.?

Oof. That is nasty. If it keeps up, the SPC is going to have to make some big-time changes for the severe weather outlook.
 
Yeah, that sounding is quite worse than the profiles we dealt with with our last outbreak

Now that's concerning. Considering our last outbreak was pretty significant by February standards. Not to mention we had days notice that we would have severe weather. We're not even in marginal category for tomorrow. I hope one of our local mets can at least mention this. Otherwise, a lot of people are going to be caught off guard.
 
Low top super cells in March no less gave me my closest encounter with a tornado....it missed the house by 200 yrds and I watched it eat a bunch of Forestry service buildings right at the firetower on Firetower Rd in Greenville....


Then there was this monster which is DAMN impressive given the "storm" it was attached too....

Not exactly the Southeast but could be indicative of some of the storms later tonight in Arkansas and Tennessee.

Beefy looking storm in Southern Illinois/Kentucky.5580D90F-7A58-4157-8CE7-28E0B74D56D2.png
 
Not that it can't change, but the fact that it was supposed to rain here today and now it's partly cloudy just screams possible forecast bust tomorrow, and not in a good way. If we don't have that main rain shield by the a.m., all bets all off. And with it being Super Tuesday tomorrow I feel like it's an omen of things to come. We've had some nasty outbreaks on election days.
 
RAP has backed off, still nasty soundings but not quite as impressive, looks like hrrr is slowing down the rain shield, which may put a damper on the severe threat
