AREAS AFFECTED...CNTRL NEB

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 210432Z - 210530Z

ISOLATED DAMAGING WIND/LARGE HAIL THREAT APPEARS TO BE INCREASING TO
THE S AND SW OF WW 653. CONVECTIVE TRENDS WILL BE MONITORED FOR A
POSSIBLE WW.

LOCAL RADAR IMAGERY SHOWS TRAILING PORTIONS OF NERN NEB MCS OUTFLOW
BOUNDARY EXTENDING SEWD THROUGH ODX TO N OF LBF. ISOLATED TSTMS HAVE
RECENTLY DEVELOPED ALONG THIS BOUNDARY OVER GARFIELD AND VALLEY
COUNTIES WITH ADDITIONAL DEVELOPMENT NOTED OVER CUSTER AND DAWSON
COUNTIES. TSTMS MAY BECOME MORE WIDESPREAD OVER THE NEXT 1 TO 3
HOURS AS THIS OUTFLOW BOUNDARY PUSHES SWD AND COLLIDES WITH SYNOPTIC
STATIONARY BOUNDARY STRETCHING FROM WEAK LOW PRESSURE OVER S-CNTRL
NEB ENEWD TO JUST N OF OMA AND DSM. WHILE DEEP-LAYER VERTICAL SHEAR
IS COMPARABLY WEAKER THAN POINTS TO THE N...PRESENCE OF MODERATELY
UNSTABLE AIR MASS SUGGESTS THE POTENTIAL FOR ORGANIZED STORM
DEVELOPMENT.

CONVECTIVE TRENDS WILL BE MONITORED AND WW MAY BECOME NECESSARY
SHOULD STORMS CONTINUE TO INTENSIFY AND BECOME MORE WIDESPREAD.
