AREAS AFFECTED...SERN NEB...CENTRAL AND WRN IA...EXTREME NWRN MO AND
NORTH CENTRAL KS

CONCERNING...SEVERE THUNDERSTORM WATCH 684...

VALID 260010Z - 260115Z

NUMEROUS STRONG TO SEVERE STORMS ARE EXPECTED ACROSS SERN NEB AND
WRN IA INTO THE EVENING HOURS. MOST INTENSE STORMS THROUGH 01Z WILL
PERSIST WITHIN AN AREA FROM WEST OF BIE NEWD TO NEAR FOD. A FEW
STORMS WITH WIND DAMAGE ARE ALSO POSSIBLE SOUTH OF THE WW ACROSS
EXTREME NORTH CENTRAL KS.

A VERY MOIST BOUNDARY LAYER..DEWPOINTS IN THE UPPER 70S...WAS
RESULTING IN A VERY UNSTABLE AIR MASS ACROSS IA...WITH MLCAPE VALUES
AROUND 3000 J/KG. DESPITE THE WARM MID LEVEL TEMPERATURES ...THE
STRONG INSTABILITY WILL SUPPORT SEVERE HAIL AND DAMAGING WINDS WITH
THE IA STORMS.

THE BOUNDARY LAYER ACROSS SERN NEB IS MUCH WARMER...TEMPERATURES IN
MID AND UPPER 90S...THAN ACROSS IA...AND DEWPOINT SPREADS 30-35F.
THE ENVIRONMENT ACROSS SERN NEB...AND EVEN INTO EXTREME NRN KS...ARE
MUCH MORE SUPPORTIVE OF DAMAGING WINDS AND STRONG MICROBURSTS...EVEN
THOUGH THE STORMS ARE ONLY MOVING ENEWD AT 20 KT.
