AREAS AFFECTED...SRN AND SERN NEB THROUGH NRN KS

CONCERNING...SEVERE THUNDERSTORM WATCH 642...

VALID 180411Z - 180515Z

WW 642 WILL EXPIRE AT 05Z. THE THREAT OF SEVERE WEATHER MAY PERSIST
A COUPLE HOURS BEYOND THIS TIME...BUT STORMS ARE EXPECTED TO UNDERGO
A GRADUAL DECREASE IN INTENSITY NEXT FEW HOURS. CURRENT THINKING IS
THAT ANOTHER WW WILL PROBABLY NOT BE NECESSARY.

STORMS CONTINUE DEVELOPING WITHIN POST FRONTAL ZONE FROM NWRN KS
THROUGH SRN NEB WHERE LIFT IS BEING ENHANCED BY THE INTENSIFYING SLY
LOW LEVEL JET. STORMS ALONG THIS PORTION OF THE FRONT HAVE BEEN
STRONGER THAN FARTHER EAST...POSSIBLY DUE IN PART TO THE PRESENCE OF
STEEP LAPSE RATES. ACTIVITY WILL LIKELY CONTINUE NEXT FEW HOURS
GRADUALLY SPREADING SEWD THROUGH SRN NEB AND NRN KS. HOWEVER...
INTENSITIES SHOULD GRADUALLY DECREASE AS THE LOW LEVEL THETA-E
SOURCE REGION ACROSS KS CONTINUES TO COOL.
