SATELLITE ANALYSIS AND TRENDS...RAPID COOLING IN EMBEDDED COLD-TOP
CONVECTION IN N.E. TEXAS AND S.E. OKLAHOMA AS WELL AS IN BROKEN WARM-TOP
CONVECTION FURTHER SOUTH IN TEXAS ALONG FRONTAL CONVERGENCE BOUNDARY.
SEVERAL OF THE WARM-TOP CELLS, ESPECIALLY ONE IN BELL COUNTY AT 1825Z,
SHOW SEVERE WEATHER SIGNATURE IN ENHANCE IR IMAGERY.  NONETHELESS,
ESTIMATES OF 1.5" PER HALF-HOUR WITH THESE CELLS AND AS MUCH AS 1.9"
PER HALF-HOUR FURTHER EAST IN LEON AND MADISON COUNTYS, WILL STILL CAUSE
PRELIMINARY PROBLEMS, DESPITE FAIRLY QUICK NORTHWARD MOVEMENT, AHEAD OF
MORE STORMS FORMING UPSTREAM.
.
COLDER TOP STORMS IN THE EASTERN RED RIVER VALLEY WILL AID IN PRODUCING
POTENTIAL FLASH FLOODING IN PREVIOUSLY SOAKED REGIONS OF S.E. OK.
A STRONG LOW LEVEL JET FLOW, ALONG WITH NEGATIVELY TILTED TROF AS EVIDENT
IN THE WV IMAGERY, HAS EFFICIENTLY TRANSPORTED HIGH PW'S AND TD'S INTO
THIS AREA SO MAX ESTIMATED RAIN RATES APPROACHING 2.0" PER HALF-HOUR
ARE LIKELY IN THE NEXT COUPLE HOURS IN COUNTIES SUCH AS LAMAR, TX AND
CHOCTAW, OK.  SUBSEQUENT TRAINING OF STORMS DURING THE NEXT 6 HR PERIOD
WILL LIKELY RESULT IN DISASTROUS FLASH FLOODING IN S.E. OK.
