AREAS AFFECTED...FAR SOUTHEAST NEB/WESTERN IA/EASTERN KS/NORTHWEST
MO

CONCERNING...SEVERE THUNDERSTORM WATCH 925...

VALID 060108Z - 060245Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 925
CONTINUES.

SEVERE TSTM WATCH 925 CONTINUES UNTIL 06Z...WITH CONTINUED RISKS OF
SEVERE HAIL/DAMAGING WINDS OVER THE NEXT FEW HOURS. CURRENT THINKING
IS THAT AN ADDITIONAL WATCH WILL NOT BE NEEDED EAST OF WW 925.

STRONGLY FORCED CONVECTIVE LINE CONTINUES TO GRADUALLY DEVELOP
EASTWARD IMMEDIATELY AHEAD OF SYNOPTIC COLD FRONT...FROM ROUGHLY
ALONG THE NEB/IA BORDER SOUTH-SOUTHWESTWARD INTO EASTERN KS NEAR THE
KS TURNPIKE. THE DEGREE OF THE FORCING/PREFRONTAL CAPPING AND
LIMITED DIRECTIONAL SHEAR SUGGESTS A CONTINUED LARGELY LINEAR
ORGANIZATION...WITH SEVERE HAIL AND DAMAGING WINDS POSSIBLE WITH
SMALL-SCALE/LINE-EMBEDDED BOWS OVER THE NEXT FEW HOURS. IN SPITE OF
BACKED LOW-LEVEL FLOW AND STRONG PREFRONTAL SRH...LIMITED BOUNDARY
LAYER MOISTURE /UPPER 50S F/ AND 00Z OBSERVED RAOBS FROM
OMAHA/TOPEKA SUGGEST THE BOUNDARY LAYER WILL BE QUITE SUSCEPTIBLE TO
NOCTURNAL DECOUPLING IN THE SHORT TERM...THUS KEEPING ANY TORNADO
THREAT REMOTE.

Just had an insane storm go through. Lots of pea to dime sized hail and 60mph winds.

Looks like a little more insanity to your southwest. Still showing a good line of cells down there.

It seems that storms really got going, but didn't get spinning which is quite surprising.

PERIODIC LOW LEVEL ROTATION /AND THUS A CONDITIONAL TORNADO THREAT/

It was on this night 3 years ago there was a terrible tornado in Evansville, Indiana out of a rogue supercell from a broken squall line. Hopefully this won't be a repeat...
