THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 121
CONTINUES. TRENDS ARE BEING MONITORED FOR THE POSSIBILITY OF AN
ADDITIONAL WW.
SUPERCELL EAST OF LAWTON PROBABLY BECAME ROOTED IN MOIST BOUNDARY
LAYER NEAR TRIPLE POINT LOW...WHERE MIXED LAYER CAPE BRIEFLY REACHED
1000 J/KG. WITH ONSET OF SURFACE COOLING ALONG/WEST OF DRY LINE
NEXT FEW HOURS...AND SOUTHWARD ADVANCEMENT OF COLD FRONT... BOUNDARY
LAYER INSTABILITY WILL DECREASE. HOWEVER...CONVECTIVE DEVELOPMENT
SEEMS LIKELY TO INCREASE IN COVERAGE THIS EVENING...AS STRENGTHENING
LOW-LEVEL JET ENHANCES WARM ADVECTION NORTHEAST OF SURFACE LOW
TRACKING THROUGH THE RED RIVER VALLEY. THIS IS JUST AHEAD OF
STRONGER MID/UPPER FORCING...WHICH IS IN THE PROCESS OF TURNING
EASTWARD ACROSS THE SOUTH CENTRAL PLAINS...TOWARD THE OZARK PLATEAU.
THE NUMBER OF HAIL PRODUCING STORMS MAY INCREASE...AT LEAST A
BIT...ACROSS CENTRAL/EASTERN OKLAHOMA THROUGH 03-06Z. A SMALL
ORGANIZED CONVECTIVE SYSTEM MAY PERSIST ON THE SOUTHERN FLANK STORM
CLUSTER...NEAR WARM FRONT. AND...IF THIS OCCURS...DAMAGING WIND
POTENTIAL COULD INCREASE IN A RELATIVELY NARROW SWATH NEAR THE RED
RIVER.
