THE OHIO VALLEY LATE. INCREASING MID LEVEL JET COMBO WITH BLYR
INSTAB CONDUCIVE TO BETTER COVERAGE ALTHO TIMING OF TRAILING TROF
AXIS CRITICAL. GFS LOOKS OVERDONE AND FAST FOR JUNE...SO PLAN TO
FOLLOW SLOWER ETA WHICH ALTHO LACKS INSTABILITY SUPPORTS TREND
TOWARD EARLY WRN TSRA...REDEVELOPING INTO THE PIEDMONT LATER THU.

INSOLATION.
