Where ist this information from. Area seems not to be populated densly...is there a coverage ?


Not that I can find. Goodland is only about 5,000 people.


So that´s the reason the set the whole area under alert i think.

Sorry, messed it up. I meant NE.

...THERE IS A MDT RISK OF SVR TSTMS FROM NWRN TX INTO WRN NEB...

...THERE IS A SLGT RISK OF SVR TSTMS SURROUNDING THE MDT RISK FROM
SWRN TX INTO CNTRL SD...

...HIGH PLAINS...

NUMEROUS DISCRETE SUPERCELL STRUCTURES HAVE EVOLVED ACROSS THE HIGH
PLAINS FROM THE TX PANHANDLE...NWD INTO WRN SD. THIS ACTIVITY
CONTINUES TO EVOLVE AHEAD OF UPPER TROUGH WITHIN VERY FAVORABLE
SHEAR ENVIRONMENT FOR SUSTAINING ORGANIZED ROTATING UPDRAFTS.
SEVERAL OF THESE SUPERCELLS HAVE ALREADY PRODUCED TORNADOES...WITH
THE GREATEST CONCENTRATION OCCURRING WITH SUPERCELLS OVER THE ERN TX
PANHANDLE...AND OVER NWRN KS JUST SOUTH OF GLD. 00Z SOUNDINGS FROM
AMA/LBF STRONGLY SUPPORT ONGOING SUPERCELL/TORNADIC THREATS WITH
MLCAPE VALUES APPROACHING 2000 J/KG. AXIS OF GREATEST CAPE NOW
EXTENDS FROM NWRN TX INTO SRN KS...WITH ANOTHER POCKET INTO WRN NEB
WHICH SHOULD PROVE BENEFICIAL AS STORMS PROPAGATE DOWNSTREAM.
ADDITIONALLY...AS LLJ INCREASES LATER THIS EVENING...IT APPEARS
ORGANIZATIONAL POTENTIAL WILL ONLY INCREASE AS LOW LEVEL SHEAR
INCREASES BENEATH 50KT LLJ. GREATEST SEVERE THREAT WILL ONLY
GRADUALLY SHIFT EWD TONIGHT AS STRONGEST HEIGHT FALLS HAVE YET TO
SPREAD INTO THE PLAINS.

FARTHER SOUTH...SEVERE THUNDERSTORMS SHOULD EVOLVE ACROSS THE TX
SOUTH PLAINS...FROM NEAR LBB...SWD ALONG ADVANCING DRY LINE/COLD
FRONT. LATEST SATELLITE IMAGERY SUGGESTS HIGH BASED CONVECTION IS
DEVELOPING ALONG THE TX/NM LINE. WITH TIME THIS CONVECTION SHOULD
DEEPEN AND THUNDERSTORMS WILL EVOLVE. SEVERE THREAT WILL INCREASE
MARKEDLY AFTER DARK ACROSS THIS PORTION OF NWRN TX. SUPERCELLS WITH
LARGE HAIL AND POSSIBLY TORNADOES COULD EVOLVE FROM THIS OVERNIGHT
CONVECTION.

...NC...

AIRMASS HAS STABILIZED SIGNIFICANTLY ACROSS NC THIS EVENING...AND
WILL CONTINUE TO DO SO AS BOUNDARY LAYER COOLS AND NELY WINDS
INCREASE WITH FRONTAL PASSAGE. IT APPEARS ONGOING CLUSTER OF
THUNDERSTORMS OVER NCNTRL NC/VA BORDER WILL PROPAGATE SEWD
ALONG/NORTH OF FRONTAL ZONE WHERE WEAK LOW LEVEL WARM ADVECTION WILL
MAINTAIN CONVECTION. HOWEVER...SEVERE THREAT WILL PROVE MARGINAL
THE REST OF TONIGHT GIVEN WEAK INSTABILITY.

Goodland, KS radar (KGLD) of Cheyenne County, KS

Nice comma shape to the cell. Triangle shows shear profile of a possible tornado. I believe this was reported 15 minutes ago as a "large wedge tornado".

Here's the rotation 3D view.

This cell is current near the Bird City, KS area.
