DISCUSSION...MAIN QUESTION CHC OF TRW THRU PD.

LOOKS PRETTY HIGH TO ME...ESPECIALLY FOR TNGT. CELLS ALREADY POPPING
UP WHEREVER THERE IS A BOUNDARY. BETTER ORGANIZED STUFF NRN NEBRASKA
AND COL NOW HEADING THIS WAY...AND STUFF OVR SERN COL ALSO HEADED
IN THIS DIRECTION. WITH WV CURVE CONSIDERING TO SHOW TROPICAL PLUME
EQUIPPED WITH WEAK IMPULSES OVER AREA AND US YET TO HIT MAXIMUM
HEATING...SOMETIME THIS AFTN OR EVE MOST PLACES SHOULD GET
MEASURABLE. HEAVY RAIN PSBL AS PER HISTORY OF STORMS UNDER TROPICAL
MOISTURE.

OTRW CLOSE TO GUIDANCE WHICH LOOKS REASONABLE IN WHATS BASICALLY A
PERSISTENCE PATTERN.
