RAH: CHC POPS THIS EVE AND TUE...SLGT CHC TUE NIGHT AND WED.

CWF: WILL TREND TOWARD ETA SOLUTION OF TROF/FRONT STALLING OVER NRN
WATERS LATE TNGT THEN REMAINING OVER AREA INTO WED. WIND SHIFT WILL
PUSH DOWN TO ILM AREA TUE THEN BECOME VRBL/SRLY BY WED. NOT
IMPRESSED WITH SWELLS FROM DANIELLE SO FAR...BUT POTENTIAL FOR 6

DISCUSSION: CELLS HAVE RAINED OUT AROUND MHX BUT WAITING FOR OTHER
ACTVTY TO DEVELOP ON OUTFLOW BNDRYS AND CHC POP FOR EVE SOUNDS GOOD.
NGM APPEARS TO LET CIRCULATION FROM DANIELLE INFLUENCE TROF/FRONT
TOO MUCH...BRINGING IT THRU MOST OF COAST. ETA/AVN PREFERRED WITH
