THE SEVERE WEATHER THREAT FOR TORNADO WATCH 292, 294 CONTINUES.
SUMMARY...THE SEVERE THREAT IS EXPECTED TO INCREASE ACROSS THE
WESTERN OZARKS EARLY THIS EVENING. TORNADOES, LARGE HAIL AND WIND
DAMAGE WILL BE POSSIBLE.
DISCUSSION...THE LATEST HI-RESOLUTION RADAR FROM TULSA SHOWS
SCATTERED SEVERE STORMS, WITH MULTIPLE SUPERCELLS AND SHORT INTENSE
LINE SEGMENTS, LOCATED FROM NORTHEASTERN OKLAHOMA EXTENDING
NORTHWARD INTO FAR WESTERN MISSOURI. THE RAP IS ANALYZING MODERATE
INSTABILITY TO THE EAST OF THE STORMS OVER MUCH OF THE OZARKS, WHERE
MLCAPE IS ESTIMATED TO BE AROUND 2000 J/KG. IN ADDITION, THE AXIS
OF A 40 TO 50 KNOT LOW-LEVEL JET IS ANALYZED FROM EASTERN OKLAHOMA
INTO WESTERN MISSOURI. THE LOW-LEVEL JET WILL GRADUALLY INCREASE AND
MOVE EASTWARD, WHICH WILL INCREASE LOW-LEVEL SHEAR ACROSS THE
WESTERN OZARKS. RAP FORECAST SOUNDINGS FOR SPRINGFIELD, MISSOURI
INCREASE 0-3 KM STORM-RELATIVE HELICITY INTO THE 300 TO 350 M2/S2
RANGE BY EARLY EVENING. IN RESPONSE, A TORNADO THREAT IS EXPECTED TO
DEVELOP ACROSS THE WESTERN OZARKS OVER THE NEXT FEW HOURS. WIND
DAMAGE WILL ALSO BE POSSIBLE WITH BOWING LINE SEGMENTS. SUPERCELLS
MAY ALSO PRODUCE LARGE HAIL.
