Severe WX December 31, 2021 - January 1, 2022 Severe Threat (4 Viewers)

[Taylor Campbell]

Substantial lightning increase with activity near Vernon and along that line. 3KM NAM and HRRR show updraft helicity streak along it as it progresses northeastward to near Cullman/I-65 around midnight.

They just issued a new watch. James Spann says he thinks theyll cancel much of it before 5 am. Maybe after midnite itll all be done.

What’s coming through Lamar and Marion looks like the main line, so I would think it would be through by 5am.

 

[Kragg]

That cluster of storms just east of Jackson MS lit off as fast as anything I’ve seen today.

ETA: surface winds from SSW have noticeably increased in the last 5-10 minutes here on the Shelby/Jefferson county line.

 

[KoD]

There's been a tremendous amount of rain here, Reality is well outside of the estimated radar totals but it feels like we've been in 55+65dBz for at least an hour straight.



I'm very surprised that my biggest concern is flash flooding vs tornadoes during this time of year, with these parameters in place. Definitely bring back some 2015 vibes for Madison County, AL.

 

[Equus]

Near continuous lightning here off to the west with that quickly intensifying solid line, not a fan of the little notches and bows it's trying to develop

Please no tornadoes! I never watch SNL but have it on tonight because Betty White's episode is on.

Yeah the line is ramping up a bit. TWC pointed this out.

 

[HTbaseballfan088]

Seems like the line is the main threat, not even severe or a special weather statement on it. Watch for notches for spin ups but I think that’s about it for the night. All the storms In front that form seem to form then weaken

 

[Equus]

Line is almost overhead and so far velocity signatures seem pretty tame, hopefully no spinups from this one; lotta lightning and wind to go though

 

[Kragg]

Anybody watching the line just south of Scottsboro? Was that maybe a quick spin up? It was gone by the next scan.

SPC issued another MD. They expect SVR risk to increase over the next few hours.

SUMMARY...RISK FOR SEVERE WEATHER -- INCLUDING POTENTIAL FOR A
COUPLE OF TORNADOES -- CONTINUES ACROSS THE WW AREAS, WITH SOME
INCREASE IN POTENTIAL EXPECTED OVER THE NEXT FEW HOURS.

DISCUSSION...LATEST WATER VAPOR LOOP SUGGESTS THAT MID- AND
UPPER-LEVEL HEIGHTS ARE GRADUALLY FALLING ACROSS THE CENTRAL GULF
COAST REGION AT THIS TIME, AS THE UPPER TROUGH CROSSING THE CENTRAL
AND SOUTHERN PLAINS ADVANCES.

SOUTH OF THE SOUTHWARD-MOVING SURFACE COLD FRONT -- NOW BISECTING
MISSISSIPPI FROM SOUTHWEST TO NORTHEAST AND EXTENDING ACROSS
NORTHERN ALABAMA AND EASTERN TENNESSEE, THE BOUNDARY LAYER REMAINS
QUITE MOIST. THIS -- COMBINED WITH THE MID-LEVEL ASCENT AIDING IN
SOME STEEPENING OF LAPSE RATES, IS HELPING TO MAINTAIN 500 TO 1000
J/KG MIXED-LAYER CAPE ACROSS THIS AREA PER RUC-BASED OBJECTIVE
ANALYSES. IN TANDEM WITH THE SUBTLY INCREASING ASCENT, AN UPTICK IN
CONVECTIVE COVERAGE/INTENSITY IS NOTED OVER THE PAST HOUR ACROSS THE
REGION, AND EXPECT THIS TREND TO CONTINUE OVER THE NEXT FEW HOURS
(IN LINE WITH HRRR AND OTHER RECENT CAM RUNS).

GIVEN THE VERY FAVORABLE BACKGROUND KINEMATIC ENVIRONMENT, RISK THAT
A FEW SEVERE/ROTATING STORMS RE-EMERGE REMAINS APPARENT. ALONG WITH
POTENTIAL FOR LOCALLY DAMAGING WINDS, A COUPLE OF TORNADOES REMAIN A
POSSIBILITY OVERNIGHT.

 

[Equus]

Line has hit here; not very much wind but lots of close lightning. Power is out; very close CG hit something very very nearby

 

[HTbaseballfan088]

I have never seen some many mds discussions for Birmingham in my life. Only one tornado warning for Lamar that lasted 8 minutes. Crazy

 

[Equus]

Can't believe I had a camera going to catch the leading edge at just the right time but hey I'm not complaining

 

[Clancy]

Goodness, that was quite the bolt right there. Always best to paly it safe with lightning.

The time is now 12:16 CST. From what I can see Birmingham stayed above 70 all 24 hours NYD. I feel fairly certain we broke the record for warmest minimum temperature ever in meteorological winter!

Hey, all! Long time lurker here, and first time posting. I make this place one of my open browser tabs when severe weather might happen. I really appreciate y'all's (all y'all's) knowledge! I've seen so many spot-on observations/predictions here. I'm impressed every time I come here. I am also fascinated by mother nature and the things she can do.

I just want to say as an outsider that sometimes, it seems like people are hoping for tornadoes, and while that is awesome to behold, it sucks for the people under the gun/potentially under the gun/lost their house or worse. So, please keep that in mind. Sorry if I stepped on toes saying this.

Haven't stepped outside in a few hours but the warmth and moisture has really been something else all day today.

I understand that balancing act well. Your amazement of the event cannot overtake your concerns for those impacted by the event. I cannot speak for others though, just myself.
