...NO SVR TSTM AREAS FORECAST...

...SRN HIGH PLAINS THROUGH CNTRL PLAINS...

TRAILING PORTIONS OF FRONTAL ZONE IS LIFTING NWD AS A WARM FRONT
THROUGH ERN AND SWRN NEB AND ERN CO. A FEW STORMS CONTINUE IN
VICINITY OF THIS BOUNDARY. OTHER STORMS ARE SPREADING OFF THE HIGHER
TERRAIN INTO THE SRN PLAINS OF ERN NM AND WRN TX. OBJECTIVE ANALYSIS
AND RAOB DATA INDICATE A NARROW AXIS OF 400-800 J/KG MLCAPE FROM ERN
NM NEWD THROUGH WRN KS...SERN NB INTO THE UPPER MS VALLEY AREA WITH
THE STRONGER INSTABILITY OVER THE SRN HIGH PLAINS.

STORMS DEVELOPING OVER THE SRN HIGH PLAINS ARE EMBEDDED WITHIN WEAK
VERTICAL SHEAR...BUT MAY REMAIN CAPABLE OF PRODUCING ISOLATED STRONG
WIND GUSTS AND MARGINALLY SEVERE HAIL INTO MID EVENING. OVERALL
TREND SHOULD BE FOR THIS ACTIVITY TO WEAKEN AS THE BOUNDARY LAYER
STABILIZES.

...MID-UPPER MS VALLEY AREA...

STORMS COULD UNDERGO SOME INCREASE IN COVERAGE AND INTENSITY FARTHER
NE ACROSS IA...SERN NEB AND WRN WI AS THE LOW LEVEL JET STRENGTHENS
THIS EVENING. ACTIVITY WILL INITIALLY BE EMBEDDED WITHIN VERTICAL
SHEAR SUFFICIENT FOR UPDRAFT ROTATION. HOWEVER...WEAK INSTABILITY
WILL SERVE AS A LIMITING FACTOR FOR ORGANIZED SEVERE STORMS...AND
EFFECTIVE SHEAR SHOULD GRADUALLY DECREASE AS THE BOUNDARY LAYER
DECOUPLES.

AREAS AFFECTED...WRN KS INTO S-CNTRL NEB

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 142148Z - 142315Z

THE POTENTIAL FOR ISOLATED SEVERE STORMS CAPABLE OF DAMAGING WINDS
AND HAIL IS EXPECTED TO CONTINUE INTO EARLY EVENING. A WW IS NOT
ANTICIPATED.

THE COMBINATION OF A STEEP LAPSE RATES...A MODERATELY UNSTABLE AIR
MASS...SURFACE FRONT...AND NEWD TRANSLATION OF A MIDLEVEL
PERTURBATION OUT OF THE SRN HIGH PLAINS HAS ALLOWED FOR AN INCREASE
IN STORM COVERAGE AND INTENSITY OVER THE PAST COUPLE OF HOURS FROM N
OF EHA TO NEAR HSI. RUC PROXIMITY FORECAST SOUNDINGS MODIFIED FOR
CURRENT SURFACE CONDITIONS YIELD MLCAPE OF AROUND 1000 J/KG AND
RATHER DEEPLY MIXED BOUNDARY LAYER CONDITIONS.

THE CONTINUED NEWD MOVEMENT TO MIDLEVEL VORTICITY MAXIMUM INTO THE
CNTRL HIGH PLAINS SHOULD SERVE TO MAINTAIN CLUSTERS OF TSTMS INTO
THIS EVENING. SURFACE-BASED STORMS SHOULD BEGIN TO DECREASE IN
COVERAGE AND INTENSITY AFTER ABOUT 02-03Z AS THE BOUNDARY LAYER
BEGINS TO COOL AND THE CAP INCREASES. IN THE MEANTIME...THE DEEPLY
MIXED BOUNDARY LAYER IN CONJUNCTION WITH DCAPE OF 500-800 J/KG AND
RELATIVELY COOL THERMODYNAMIC PROFILES WILL BE SUPPORTIVE OF
ISOLATED STRONG WIND GUSTS AND MARGINALLY SEVERE HAIL.

A REINFORCING SURGE OF CONTINENTAL AIR WILL OVERSPREAD THE SRN
