.SHORT TERM...(TONIGHT AND SATURDAY)...UPPER FLOW WILL BECOME MORE
ZONAL THE NEXT 24 HOURS AS TROUGH OVER THE NORTHEAST UNITED STATES
MOVES EAST. HEIGHT RISE ARE IN STORE FOR THE SOUTHERN
APPALACHIANS...SO WARMER TEMPERATURES CAN BE EXPECTED FOR SATURDAY.
ONLY FLY IN THE OINTMENT WILL BE ANY DYING MCS FROM THE MID-
WEST/WESTERN OHIO VALLEY PULLING CLOUD COVER INTO THE
REGION...MAINLY OVERNIGHT.

VISIBLE SATELLITE SHOWED FOG...SOME DENSE ACROSS THE VALLEYS OF
SOUTHWEST VIRGINIA AND FAR NORTHEAST TENNESSEE THIS MORNING. NAM
SHOWS THE POTENTIAL OF SEEING SOME PATCHY DENSE FOG THERE TONIGHT.

NAM AND GFS SHOW INCREASING MOISTURE THE NEXT 24 HOURS AS SURFACE HIGH
MOVES EAST OF THE REGION WITH A SLOW RISE OF PWS. AIRMASS WILL BECOME
QUITE UNSTABLE FOR SATURDAY AFTERNOON WITH CAPES AROUND 2500 J/KG AND
LIFTED INDICES OF -6 TO -7. HOWEVER...ONLY LIFTING MECHANISM WILL BE
LOCAL TERRAIN. WILL ADD A SLIGHT POP FOR THE MOUNTAINS ZONES FOR
TOMORROW AFTERNOON/EVENING.

.LONG TERM...(SAT NIGHT THROUGH FRI)...LOOKS LIKE ATMOSPHERE WILL
BE RATHER DRY ON SUNDAY...AND MODELS SHOWING A DRIER MONDAY NOW AS
WELL. INSTABILITY LOOKS LIMITED...AND WITH NO SIGNIFICANT FORCING
EXPECTED WILL KEEP THINGS DRY SUNDAY...AND CONTINUE CURRENT
FORECAST OF SLIGHT CHANCE POPS MONDAY FOR NOW. GFS HAS BACKED OFF
ON MOISTENING THINGS UP SO QUICKLY TUESDAY NOW AS WELL...AND WOULD
NOT BE SURPRISED TO SEE THAT TREND CONTINUE WITH FRONT STILL WELL
TO OUR NORTH. WILL CONTINUE WITH LOW CHANCE POPS TUE FOR NOW...BUT
LATER MODEL RUNS MAY PROMPT A CHANGE INTO THE SLIGHT CHANCE RANGE.
STILL LOOKS LIKE A COLD FRONT WILL SAG INTO THE AREA IN THE WED OR
WED NIGHT TIME FRAME...AND SHOULD PASS TO OUR SOUTH BY THU.
HOWEVER...CONFIDENCE NOT HIGH ON HOW FAST/HOW FAR SOUTH THIS FRONT
WILL MAKE IT. AFTER CHANCE POPS FOR WED AND WED NIGHT...WILL KEEP
SLIGHT CHANCE GOING INTO THU. DRY THU NIGHT AND FRIDAY FOR
NOW...ASSUMING FRONT DOES INDEED MAKE IT SIGNIFICANTLY SOUTH OF OUR
AREA...BUT CONFIDENCE LOW FOR LATTER PART OF FORECAST. WILL MAKE A
FEW TWEAKS TO GFS MOS TEMPS...BUT OVERALL THEY LOOK TO BE IN THE
BALLPARK.
