VALID 071300Z - 081200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE CENTRAL AND SOUTHERN HIGH PLAINS...
..SUMMARY
A FEW STRONGER THUNDERSTORMS CAPABLE OF MARGINALLY SEVERE WIND
GUSTS/HAIL ARE POSSIBLE ACROSS PORTIONS OF THE CENTRAL AND SOUTHERN
HIGH PLAINS LATE THIS AFTERNOON THROUGH THE EARLY EVENING.
..CENTRAL/SOUTHERN HIGH PLAINS
MORNING WATER-VAPOR IMAGERY SHOWS A LOW/TROUGH OVER THE EASTERN
PACIFIC WITH A DOWNSTREAM RIDGE OVER THE ROCKIES. A COUPLE OF WEAK
DISTURBANCES ARE CRESTING THE RIDGE AND MAY AID IN STORM DEVELOPMENT
LATER THIS AFTERNOON/EVENING OVER THE CENTRAL HIGH PLAINS LATER
TODAY.
IN THE LOW LEVELS, A LEE TROUGH AND AN ASSOCIATED MOISTURE PLUME
OVER THE HIGH PLAINS WILL PROVIDE A FOCUS FOR ISOLATED TO WIDELY
SCATTERED STORMS. STRONG HEATING OVER THE HIGH PLAINS WILL
CONTRIBUTE TO WEAK TO MODERATE BUOYANCY BY LATE AFTERNOON.
SOUTH-SOUTHEASTERLY LOW-LEVEL WINDS VEERING TO AROUND 20-KT
NORTHWESTERLY MID-LEVEL FLOW WILL SUPPORT SOME MODEST UPDRAFT
ORGANIZATION. THE STRONGER STORMS MAY YIELD AN ISOLATED SEVERE-HAIL
(DIAMETER 1.5 INCHES OR LESS) AND WIND-GUST (55-65 MPH) THREAT. A
SMALL CLUSTER OR TWO IS EXPECTED TO EVOLVE DURING THE EVENING
COINCIDENT WITH AN INCREASE IN THE LLJ. THIS ACTIVITY WILL LIKELY
MOVE EAST-SOUTHEAST INTO WESTERN KS AND THE OK/TX PANHANDLES, WHERE
A COOLING BOUNDARY LAYER AND INCREASING CINH WILL ACT TO LIMIT
SEVERE POTENTIAL BY MID-LATE EVENING.
