AREAS AFFECTED...NORTHWESTERN OKLAHOMA INTO SOUTH CENTRAL KANSAS
CONCERNING...TORNADO WATCH 130...
VALID 172238Z - 180045Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 130 CONTINUES.
SUMMARY...STRONG THUNDERSTORM DEVELOPMENT MAY CONTINUE TO POSE A
RISK FOR LARGE HAIL AND LOCALLY STRONG SURFACE GUSTS INTO THE 7-9 PM
CDT TIME FRAME.
DISCUSSION...CONVECTION HAS EVOLVED INTO A BROKEN BAND WITH EMBEDDED
SUPERCELLS, WHICH NOW APPEARS ROOTED ABOVE THE SHALLOW LEADING EDGE
OF A SOUTHWARD ADVANCING COLD FRONT. WHILE THE DEEPER COLD AIR AND
MORE NOTABLE SURFACE PRESSURE RISES ARE STILL WELL TO THE NORTHWEST,
AND IT MAY STILL BE SEVERAL HOURS BEFORE A MORE NOTABLE SOUTHWARD
PROGRESSION OF THE CONVECTION OCCURS, CONVECTIVE OUTFLOW IS
REINFORCING THE STABLE AIR BENEATH THE STRONGER CONVECTION. EVEN
SO, ELEVATED INFLOW OF MOIST AIR CHARACTERIZED BY MODERATE TO LARGE
CAPE, IN THE PRESENCE OF STRONG CLOUD-BEARING SHEAR, MAY MAINTAIN
VIGOROUS THUNDERSTORM DEVELOPMENT WITH POTENTIAL TO PRODUCE LARGE
HAIL, AND PERHAPS LOCALLY STRONG SURFACE GUSTS, INTO EARLY EVENING.
