AREAS AFFECTED...PARTS OF THE TX/OK PANHANDLES...WESTERN INTO
NORTH-CENTRAL OK...SOUTH-CENTRAL KS
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 040527Z - 040800Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...THUNDERSTORMS WITH ISOLATED LARGE HAIL AND PERHAPS LOCALLY
GUSTY WINDS ARE POSSIBLE OVERNIGHT.
DISCUSSION...ELEVATED CONVECTION HAS RECENTLY DEVELOPED ACROSS PARTS
OF THE TX PANHANDLE, WITH INCREASING MIDLEVEL CUMULUS NOTED INTO FAR
NORTHWEST OK. A FURTHER INCREASE IN ELEVATED CONVECTION IS EXPECTED
WITH TIME OVERNIGHT, AS A MID/UPPER-LEVEL SHORTWAVE TROUGH CURRENTLY
OVER THE CENTRAL/SOUTHERN ROCKIES BEGINS TO IMPINGE UPON A RESERVOIR
OF MODERATE ELEVATED BUOYANCY (WITH MUCAPE OF 1000-2000 J/KG).
STEEP MIDLEVEL LAPSE RATES (AS NOTED IN REGIONAL 00Z SOUNDINGS) AND
STRONG MID/UPPER-LEVEL FLOW (WITH EFFECTIVE SHEAR OF NEAR/ABOVE 40
KT) ARE FAVORABLE FOR ORGANIZED ELEVATED STORMS WITH LARGE HAIL,
POTENTIALLY INTO THE 1.5 - 2 INCH DIAMETER RANGE. HOWEVER, RECENT
CAM GUIDANCE GENERALLY DEPICTS A TRANSITION TO A CLUSTER OR LINEAR
MODE WITH TIME, WHICH COULD TEMPER THE MAGNITUDE AND COVERAGE OF THE
HAIL THREAT TO SOME EXTENT. ALSO, DESPITE A SUBSTANTIAL COOL/STABLE
NEAR-SURFACE LAYER TO THE NORTH OF AN ADVANCING COLD FRONT, LOCALLY
GUSTY SURFACE WINDS CANNOT BE RULED OUT IF ANY SUBSTANTIAL
CLUSTERING OR UPSCALE GROWTH OCCURS.
