MESOSCALE DISCUSSION 1578
NWS STORM PREDICTION CENTER NORMAN OK
1219 AM CDT FRI JUL 09 2004

AREAS AFFECTED...NCNTRL KS AND SERN NEB

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 090519Z - 090615Z

A SEVERE TSTM WATCH WILL BE NEEDED ACROSS PARTS OF NCNTRL KS AND
SERN NEB IF TSTMS DO NOT SHOW SIGNS OF WEAKENING.

WIDESPREAD WIND DAMAGE IS STILL BEING REPORTED WITH THE LINE OF
TSTMS ACROSS SCNTRL NEB.  OBJECTIVE ANALYSIS DEPICTS INSTABILITY
AXIS EXTENDING SEWD INTO NCNTRL KS.  GIVEN SLY H85 JET OF 30-40 KTS
AND MAGNITUDE OF INSTABILITY...THESE TSTMS WILL PROBABLY PRODUCE
WIND DAMAGE FOR A FEW MORE HOURS.  LINE IS MOVING SEWD AT AROUND 45
KTS...AND DESPITE WEAK H5 FLOW...TSTMS APPEAR TO HAVE GENERATED
ENOUGH OF A COLD POOL TO SUSTAIN A DAMAGING WIND THREAT.  IF TSTMS
DO NOT WEAKEN SOON...ANOTHER WW WILL BE NEEDED DOWNSTREAM.
