.DISCUSSION...

PROBLEM OF DAY IS PRECIP CHANCES INTO WEEKEND.

FRONT HAS STAGGERED INTO AREA AND IS SLOWLY MOVING SOUTH. MOST
PRECIP SOUTH OF BOUNDARY...BUT NOT ALL IS. STILL TROUGHY ALOFT. I
CAN CERTAINLY SEE HIGH CHC POPS...WHICH IS WHAT MOST MODELS GIVE.

THURSDAY MODELS CONCUR ABOUT FRONT BEING SOUTH OF AREA AND WEATHER
STAYING RELATIVELY DRY INTO FRIDAY. QUESTION IS WHAT RELATIVELY DRY
REALLY MEANS. I AM LEANING TOWARD DRIER MET BECAUSE GFS SEEMS
AFFECTED BY CONVECTIVE FEEDBACK...AS HAS OFTEN HAPPENED LATELY. WILL
SHADE A LITTLE UP FROM MET FOR CONSENSUS. PRATICALLY THIS
MEANS I WILL GO SLGT CHC FRIDAY IN MANY PLACES MET WOULD HAVE DRY.

TEMPERATURES NEXT FEW NIGHTS LOOK GOOD FROM CONTINUITY. NOT SO SURE
ABOUT DAYS. GUIDANCE RECOVERS RAPIDLY FOR GROUND BEING SO WET. I AM
GOING TO GO A DEGREE OR TWO BELOW THE MILD FWC THURSDAY AND FRIDAY.

IND WATCHES/WARNINGS/ADVISORIES...NONE.
