TX ON WATER VAPOR LOOP.  QUITE A BIT OF SHEAR WITH 20KT SWLY WINDS
ALOFT AT 300-500MB AND LOW LEVEL LIGHT EAST TO NE WINDS BELOW 850MB.
SO THERE COULD ALSO BE SOME DEFORMATION AS WELL AND WITH SLOW MOVEMENT
AND HIGH MOISTURE..ANYTHING THAT COOLS RAPIDLY...LIKE IN AREA FROM
CLARK-PIKE COUNTY BORDER AREA TO JEFFERSON COUNTY CAN GET 1-2 INCHES IN
A 20-45 MINUTE TIME PERIOD AND MORE THAN 2 INCHES IN A COUPLE OF HRS.
NEXT AREA OF CONCERN IN THE VIC OF PIKE AND CLARK COUNTY WHERE COOLING
HAS LEVELED OFF BUT COOL TOP HAS EXPANDED.  STILL JEFFERSON COUNTY CLOUD
TOP CELL IS COOLER BY ABOUT 5C THE PIKE-CLARK COOL TOP AND SHOULD BE
PRODUCING HIGHER AMOUNTS OF RAIN.   IN THE NEXT 1-2HRS...SOME CONCERN
