Severe Weather 2026

[Kds86z]

SUMMARY...A LOCALIZED CORRIDOR OF HIGHER TORNADO POTENTIAL MAY
PERSIST FOR THE NEXT COUPLE OF HOURS ACROSS FAR SOUTHEAST SOUTH
DAKOTA INTO ADJACENT PORTIONS OF IOWA AND NEBRASKA.

DISCUSSION...ADDITIONAL TORNADIC SUPERCELLS HAVE EMERGED IMMEDIATELY
WEST OF THE SIOUX FALLS, SD AND THE I-29 CORRIDOR BASED ON RADAR
IMAGERY FROM KFSD. NEAR-STORM 0-1 KM SRH SAMPLED BY THE LOCAL VWP
HAS RECENTLY INCREASED TO AROUND 200 M2/S2 IMMEDIATELY AHEAD OF THE
APPROACHING STORMS. CONSEQUENTLY, THE NEAR-STORM ENVIRONMENT IS MORE
FAVORABLE FOR TORNADOES THAN PREVIOUSLY ANTICIPATED, THOUGH STORM
INTERACTIONS APPEAR TO BE MODULATING THE DURATION OF THE TORNADO
THREAT TO SOME DEGREE. ADDITIONAL SUPERCELL DEVELOPMENT IS NOTED ON
THE SOUTHERN FLANK OF THE EMERGING CLUSTER, AND IS ALREADY SHOWING
SIGNS OF AN ORGANIZING LOW-LEVEL MESOCYCLONE. IT APPEARS LIKELY THAT
SOME TORNADO THREAT WILL LIKELY CONTINUE FOR THE NEXT 1-2 HOURS -
MOST LIKELY ON THE SOUTHERN FLANK OF THE CLUSTER AS IT MIGRATES
EAST/SOUTHEAST INTO FAR NORTHEAST NE/NORTHWEST IA. BASED ON THE
NEAR-STORM ENVIRONMENT AND OBSERVED VELOCITY SIGNATURES, A STRONG
TORNADO APPEARS POSSIBLE.

A Slight Risk is out for this afternoon/evening for the Tennessee Valley with an MCS forecast to move through that area.

They just upgraded the wind threat minute ago. 30 percent t

Heads up, a lot talking about Kansas today but SE Montana is the bag today. Negotiable moisture with long straight hodos, capable of large hail and a tornado threat. The better low level shear may be down south but the TD spreads are HORRIBLE
.

 

[Ozonelayer]

Wouldnt be shocked for a bit of a tornado tgreat in montana today. T/D spreads are MUCH better than KS and low level shear is comparable.

MCS advancing southward through southern Tennessee right now. Will make its way into the rest of the Southeast today. A Severe Thunderstorm Watch is in effect for parts of TN, MS and AL. SPC has a 30% wind risk over parts of the South.

GEFS Ensembles are 50/50 on a potential big day in South Dakota and Nebraska on Thursday. Temp-DP spreads are the big question mark.

Mississippi has been spared most of this line, but Alabama's been getting hammered for a while. Glad it's just popup showers around here.

 

[akt1985]

A new Severe Thunderstorm Watch is out for a large part of Arkansas for the next MCS.

 

[TornadoFan]

Tornado warned storm SE of Denver International Airport.

 

[Clancy]

Couldn't ask for a more classic-looking Deep South MCS across central Alabama right now.

 

[JPWX]

I'm hoping for more storms later this evening to put GoPro out to get lightning.

 

[JPWX]

We should get more activity here across Northeast MS. Sun came out right after the first round passed through and we were more on the outer edge of it too. Surface based CAPE remains pretty high too.
