...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE EASTERN TEXAS PANHANDLE INTO WESTERN OKLAHOMA...
..SUMMARY
SCATTERED SEVERE THUNDERSTORMS ARE EXPECTED LATE THIS AFTERNOON INTO
TONIGHT FROM NORTHWEST TEXAS AND THE TEXAS PANHANDLE INTO WESTERN
OKLAHOMA AND SOUTHERN/CENTRAL KANSAS. LARGE TO VERY LARGE HAIL, A
FEW TORNADOES, AND SEVERE/DAMAGING WINDS ARE POSSIBLE.
..SOUTHERN/CENTRAL PLAINS
AN UPPER TROUGH WILL AMPLIFY OVER THE WESTERN U.S. TODAY AS A BROAD
ZONE OF MODESTLY ENHANCED MID-LEVEL SOUTHWESTERLY FLOW PERSISTS OVER
THE SOUTHERN/CENTRAL PLAINS. AT THE SURFACE, LEE CYCLOGENESIS IS
FORECAST TO OCCUR ACROSS EASTERN COLORADO THROUGH THIS EVENING,
WHICH WILL PROMOTE CONTINUED NORTHWARD TRANSPORT OF LOW-LEVEL
MOISTURE ACROSS TEXAS INTO OKLAHOMA/KANSAS. A SURFACE DRYLINE WILL
ALSO EXTEND SOUTHWARD FROM THE LOW OVER THE SOUTHERN HIGH PLAINS.
MULTI-LAYER CLOUD COVER REMAINS SEMI-PREVALENT AT LATE MORNING BUT
PERIPHERAL GRADUAL CLEARING IS NOTED ACROSS PARTS OF WESTERN NORTH
TEXAS AS WELL AS ALONG THE NEW MEXICO/TEXAS BORDER VICINITY. THE
STRONGEST HEATING/MIXING WILL OCCUR IN VICINITY ACROSS FAR
WEST/NORTHWEST TEXAS, BUT IT SEEMS PROBABLE THAT STORM DEVELOPMENT
WILL OCCUR WITHIN THE SOMEWHAT RICHER MOISTURE NEAR/JUST EAST OF THE
CAPROCK ESCARPMENT INCLUDING PARTS OF LOW ROLLING PLAINS AND
TEXAS/SOUTHWEST OKLAHOMA BORDER VICINITY. SUCH DEVELOPMENT SHOULD
OCCUR BY AROUND 4PM-6PM CST AS CONVECTIVE TEMPERATURES ARE BREACHED.
SOMEWHAT MODEST/NEBULOUS LARGE-SCALE ASCENT WILL PROBABLY SUPPORT A
MULTI-HOUR PERIOD OF SEMI-DISCRETE SUPERCELLS EVEN IF EFFECTIVE
SHEAR IS NOT ROBUST AND LOW-LEVEL SHEAR/SRH A BIT MODEST DURING TIME
OF INITIAL DEVELOPMENT, BUT NONETHELESS STEADILY STRENGTHENING
TOWARD/AFTER 00Z/6PM CST. THIS WILL INCLUDE ASSOCIATED THREATS FOR
LARGE TO VERY LARGE HAIL INITIALLY, POTENTIALLY UP TO 2-3 INCHES IN
DIAMETER. THE INCREASING LOW-LEVEL SHEAR THROUGH THE EVENING WILL
ALSO FOSTER ENLARGED LOW-LEVEL HODOGRAPHS AND THE POTENTIAL FOR A
FEW TORNADOES WITH THIS ACTIVITY, POTENTIALLY INCLUDING A
SPATIOTEMPORAL WINDOW FOR A STRONG (EF2+) TORNADO EVEN IF A MORE
COMPLEX MODE IS EVOLVING. OVER TIME, CONVECTION IS FORECAST TO GROW
UPSCALE INTO A SMALL BUT POTENTIALLY INTENSE CLUSTER AS IT MOVES
NORTHEASTWARD INTO PARTS OF WESTERN/NORTHERN OKLAHOMA AND SOUTHERN
KANSAS.
ISOLATED SUPERCELLS MAY ALSO OCCUR ALONG THE LENGTH OF THE DRYLINE
ACROSS WEST TEXAS LATE THIS AFTERNOON/EVENING, WITH ASSOCIATED
THREAT FOR OCCASIONAL LARGE HAIL AND SEVERE WIND GUSTS. HOWEVER,
CONFIDENCE IN ANY MORE THAN ISOLATED COVERAGE REMAINS LOW DUE TO
WEAK LARGE-SCALE FORCING. FARTHER NORTH, ISOLATED SEVERE HAIL MAY
OCCUR TONIGHT WITH ELEVATED CONVECTION IN A LOW-LEVEL WARM ADVECTION
REGIME ACROSS EASTERN NEBRASKA, NORTHWEST MISSOURI INTO IOWA.
..OHIO VALLEY TO THE CENTRAL APPALACHIANS
A MID-LEVEL SHORTWAVE TROUGH WILL MOVE QUICKLY EASTWARD TODAY ACROSS
THE OHIO VALLEY. MODEST LOW-LEVEL MOISTURE WILL REMAIN IN PLACE
ALONG/SOUTH OF A FRONT, WITH GENERALLY WEAK INSTABILITY FORECAST
ACROSS THE WARM SECTOR. EVEN SO, SUFFICIENTLY STRONG LOW TO
MID-LEVEL WINDS ASSOCIATED WITH THIS SHORTWAVE TROUGH MAY PROMOTE A
FEW INSTANCES OF DAMAGING WINDS WITH LOOSELY ORGANIZED CLUSTERS THAT
DEVELOP AND SPREAD EASTWARD THROUGH THE AFTERNOON.
..FLORIDA PENINSULA
BENEATH AN UPPER HIGH AND WITHIN AN EASTERLY LOW-LEVEL FLOW REGIME,
STRONG HEATING WILL OCCUR TODAY ACROSS THE FLORIDA PENINSULA, WITH
DEWPOINTS DROPPING INTO THE MID 60S F. DESPITE THE UPPER HIGH,
MID-LEVEL TEMPERATURES (-11 OR -12C AT 500MB) WILL REMAIN RELATIVELY
COOL. SCATTERED CONVECTION APPEAR PROBABLE ALONG THE WESTERN FLORIDA
PENINSULA DURING THE AFTERNOON WHERE LOW-LEVEL CONVERGENCE WILL BE
MAXIMIZED. LOCALLY STRONG WIND GUSTS WILL BE POSSIBLE, ALTHOUGH
ORGANIZED SEVERE THUNDERSTORMS ARE NOT EXPECTED.
