NORMAL FOR THE REMAINDER OF THE WORK WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
STRATUS CONTINUES TO PLAGUE THE AREAS FROM MORGANTOWN TO UNIONTOWN
AND ALL POINTS SOUTHWARD. MODEL SOUNDINGS SUGGEST THIS SHOULD MIX
OUT IN THE NEXT FEW HOURS WITH CONTINUED DRY ADVECTION TAKING
PLACE INTO THE FORECAST AREA. HOWEVER...JUST ENOUGH LOW LEVEL
MOISTURE MAY BE LEFT AROUND FOR AN ISOLATED SHOWER ON A RIDGE TOP
THIS AFTERNOON. ELSEWHERE...DRY AIR HAS MOVED IN SUFFICIENTLY TO
PRECLUDE SHOWER DEVELOPMENT...IF NOT MOST CLOUD DEVELOPMENT AS
WELL. FRIES
-- End Changed Discussion --

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/...
-- Changed Discussion --
HIGH PRESSURE AND DRY AIR WILL MAINTAIN A MOSTLY CLEAR SKY THROUGH
FRIDAY. TEMPERATURES WILL BE NEAR NORMAL.

THE ECMWF HAS A DISTINCT SHORTWAVE APPROACHING THE FORECAST AREA
LATE SATURDAY FROM THE GREAT LAKES. THE GFS KEEPS THE REGION IN A
RIDGE OF HIGH PRESSURE...HENCE...THE WELL ABOVE MAX TEMPERATURES
THE GFSX MOS GUIDANCE IS DISPLAYING. THEREFORE...HAVE USED HPC
GUIDANCE FOR TEMPERATURES AND POPS FOR SATURDAY.

WARM AND HUMID CONDITIONS ARE FORECAST INTO EARLY NEXT WEEK AS
UPPER LEVEL RIDGE IS STILL PROJECTED TO BUILD OVER THE SRN CONUS
AS SHORTWAVES MOVE EAST IN FAIRLY ZONAL FLOW ACROSS THE GREAT
