Weird. The 1630 outlook was history within 20 minutes.

I think if the outlook was issued at 1700Z, a high risk might have been issued. I could understand holding back then. But I don't see this letting up anytime soon.

Due to this mess, any upgrades might be interesting für meteo crowd, but changing outlooks doesn´t change anything right now.

CONCERNING...TORNADO WATCH 131...

VALID 101826Z - 101930Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 131 CONTINUES.

SEVERE THREAT WILL CONTINUE ALONG AND AHEAD OF COLD FRONT OVER PARTS
OF SRN IL / SRN IN / AND W-CNTRL KY. INCREASING SEVERE POTENTIAL IS
LIKELY IN THE NEXT HR OR TWO OVER PORTIONS OF S-CNTRL KY /I-75

COMPLEX SURFACE SETUP EVOLVING ACROSS PARTS OF THE LOWER OH VALLEY
AS LOW NEAR THE MS/OH RIVER CONFLUENCE TRACKS EWD AS ATTENDANT COLD
FRONT MOVES E WITH W-E ORIENTED WARM FRONT SITUATED ALONG THE OH
RIVER. RECENT TRENDS IN RADAR MOSAIC SHOW INITIAL BROKEN LINE OF
STORMS OVER CNTRL KY HAVE WEAKENED CONSIDERABLY. HOWEVER...DISCRETE
STORMS FURTHER W /ESPECIALLY POTENTIALLY TORNADIC HP-SUPERCELL OVER
MUHLENBERG COUNTY/ WILL CROSS MOIST/INSTABILITY AXIS WITHIN THE NEXT
HR PERHAPS MAINTAINING ISOLD TORNADIC POTENTIAL. UPDRAFTS THAT CAN
BE SUSTAIN THEMSELVES IMMEDIATELY AHEAD OF LOW ALONG OH RIVER
CORRIDOR MAY POSE A LARGE HAIL THREAT BUT WEAKER LOW LEVEL SHEAR
/BELOW 20 KTS/ PER OBJECTIVE ANALYSIS MAY LIMIT TORNADO THREAT.

FARTHER E OVER E-CNTRL KY...ELEVATED STORMS WILL LIKELY POSE A HAIL
THREAT WITH STRONGER CORES LOCATED WITHIN WARM ADVECTION WING. AN
INCREASING TORNADIC THREAT ACROSS THE SRN TIER COUNTIES OF S-CNTRL

REQUIRED DOWNSTREAM OF WW 131.
