DISCUSSION…THE WARM FRONT CONTINUES TO PROGRESS INLAND IN ADVANCE
OF A PRE-FRONTAL BAND OF STORMS ASSOCIATED WITH AN EJECTING MIDLEVEL
TROUGH. THOUGH LAPSE RATES ARE NOT PARTICULARLY STEEP…BOUNDARY
LAYER DEWPOINTS IN THE 68-70 F RANGE WILL SUPPORT SURFACE-BASED
BUOYANCY IN THE WARM SECTOR. VERTICAL SHEAR WILL BE STRONGEST ALONG
THE WARM FRONT…WHERE THE RISK FOR A COUPLE OF TORNADOES WILL BE
FOCUSED. OTHERWISE…AN ISOLATED TORNADO AND A FEW DAMAGING GUSTS
WILL BE POSSIBLE WITH THE BAND OF STORMS FARTHER TO THE S INTO THE
FL PANHANDLE THROUGH THE AFTERNOON.

SPORADIC STORMS CAPABLE OF LOCALLY DMGG WIND AND A TORNADO OR
TWO…ESPECIALLY ALONG AND S OF I-10/12.

DISCUSSION…STORMS ARE INCREASING FROM EXTREME SRN SD INTO FAR NRN
NEB AS AN OUTFLOW BOUNDARY INTERSECTS A LOW-LEVEL MOISTURE
FEED…WHILE ADDITIONAL STORMS ARE DEVELOPING OVER THE BLACK HILLS
AND INTO FAR NWRN SD. THE AIR MASS IS DESTABILIZING OVER WRN SD IN
THE WAKE OF EARLIER STORMS…WITH STRONG INSTABILITY NOTED SWD INTO
NEB WHERE MLCAPE REACHES 2500-3000 J/KG. SUFFICIENT VERTICAL SHEAR
/30-40 KT IN THE LOWEST 6 KM AGL/ OVER THE AREA IN ADVANCE OF A
SUBTLE SHORT WAVE TROUGH ADVANCING EWD ACROSS MT AND WY WILL ENHANCE
SEVERE POTENTIAL. STRONGER STORMS INCLUDING A FEW SUPERCELLS WILL
BE CAPABLE OF PRODUCING LARGE HAIL AND DAMAGING WIND GUSTS…WITH
THE THREAT SPREADING SEWD THROUGH THE EVENING HOURS.
