RECOMMENDATIONS...

WBC...I THINK YOU CD GO MO CLR SAT NIGHT AND GO W/ "LESS HUMID" SUN.

CRW...KEEP CHC TRW/RW THRU EVENING...THE PC OVNT.  PTLY SNY
TMRW...MO CLR TMRW NIGHT...MO SNY SUN.  TEMPS CLOSE TO MOS.  MIGHT
ALSO TALK ABT LESS HUMID SUNDAY WX.

RDU...THREAT OF TSTMS TO CARRY THRU EVE. XPCT MORE SUNSHINE TMRW
ACROS N CNTRL PARTS THAN NW MOUNTAINS.  TEMPS CLOSE TO MOS.

DISCUSSION...

BREAK IN THE HUMIDITY ON THE WAY AS DWPT/COOL FNT CONT TO SLIDE SW
ACRS MID ATLANTIC (AS SEEN ON COOL SAT PICS).  TSTMS WHICH HAVE
DVLPED OVR SE WV/SW VA BRINGING SM MUCH NEEDED PCPN.  THESE STORMS
APPR TO BE FIRING OUT AHD OF SML VORT MAX WHICH IS INITIATING BIGGER
AREA OF TSTMS OVR OHIO.  STILL BELIEVE THAT DVLPMENT IS CLOSELY TIED
TO TIME OF DAY AS WELL AS VORT...TSTMS WHICH DO FORM DURING LATE AFT
SHD CONT TO FEED OFF UNSTBL AIR THRU EVE.  NEW DVLPMENT SHD BE
LIMITED DURING LATER EVENING HOURS AS VORT BEGINS TO WEAKEN.  CAN
SEE WHERE SM MAY LINGER AFT MID...BUT THREAT NOT BIG ENUF TO CARRY IN
ZONES.

TIME SXNS SHOW LOTS OF DRYER AIR ALF DURG LT PDS...AND W/ RIDGE
OVHD...DON/T SEE MUCH I N THE WAY OF CLDS FOR SAT NIGHT.  THINK
RESIDUAL LOW LVL MOISTURE WL SPRING ENUF CU TO JUSTIFY PTLY SNY
TMRW...THEN THIS WL GO BY THE WAYSIDE TMRW NIGHT.  LIKE MORE
OPTIMISTIC APPRCH TO SUNSHINE ON SUNDAY.
