Severe Thunderstorm Warning 228, NWS Blacksburg, VA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
316 PM EDT MON AUG 7 2006

.SHORT TERM /TONIGHT THROUGH TUESDAY/...

MORNING CONVECTION HAS STABILIZED MUCH OF THE FCST AREA AND MOST
STORMS ARE FORMING TO THE WEST AND SOUTH OF OUR REGION THIS
AFTERNOON. THIS ACTIVITY WAS MOVING SE SO BEST CHCS OF STORMS THIS
EVENING WILL BE IN THE WEST. DEEP NW ALOFT AND RELATIVELY STABLE AIR
WILL INHIBIT CONVECTION FROM ABOUT ROA EAST THIS EVENING.

WESTERN SLOPES COULD REMAIN ACTIVE OVERNIGHT AS MORE ENERGY ASSOC
WITH FRONTAL BNDRY DROPS SE OUT OF THE OHIO VALLEY. LIKE TODAY
CONTINUING DEEP NW FLOW ALOFT WILL KEEP THE BEST ACTION IN THE WEST.
SAME PATTERN CONTINUES TMRW AS FRONTAL BNDRY APPROACHES. DAYTIME
HEATING WILL FIRE UP CONVECTION ALONG LEE TROF IN THE EAST. JUST A
MATTER OF WHERE IT SETS UP. MORE THAN LIKELY IT WILL BE JUST EAST OF
THE FCST AREA.

RAIN AND CLOUDS KEPT SOME AREAS IN THE 70S AND LOWER 80S THROUGH
EARLY THIS AFTERNOON. AREAS LIKE SOUTHSIDE VA HAD MORE SUN WHICH
ALLOWED TEMPERATURES TO WARM INTO THE LOWER 90S. COULD SEE THE SAME
TEMPERATURE PATTERN ON TUESDAY.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...

FRONTAL BOUNDARY TO SLOWLY PUSH THROUGH THE AREA TUESDAY NIGHT WHILE
HIGH PRESSURE TAKES RESIDENCE IN NE USA. AT LEAST THAT WAS WHAT THE
06Z MODELS WERE SHOWING. 12Z NAM-WRF AND GFS NOT PUSHING BOUNDARY AS
FAR SOUTH AS PREVIOUS RUNS. MODELS PREDICTING 850 BOUNDARY TO BECOME
STATIONARY NEAR THE VA/TN-VA/NC BORDER WITH A WAVE RIDING ALONG IT
ON WEDNESDAY. BULK OF PRECIP TO FALL IN SW VA (MTN EMPIRE) AND NW NC
HIGHLANDS. WITH DRY AIR FILTERING INTO THE REGION TUESDAY NIGHT AND
WEDNESDAY...I AM THINKING MODELS ARE TO BULLISH WITH AMOUNTS AND
SHOULD WILL REMAIN SPOTTY AND LIGHT IF IT DOES RAIN. WENT AHEAD AND
ADDED 20/30 POPS IN SW CWA.

FROM THURSDAY THROUGH MONDAY...WENT WITH HPC GUIDANCE WHO FAVORED
THE ECMWF. A COLD FRONT WILL APPROACH THE AREA THURSDAY NIGHT AND
MOVE THROUGH THE REGION FRIDAY NIGHT/SATURDAY. NEAR NORMAL
TEMPERATURES CAN BE EXPECTED UNTIL THE FRONTAL PASSAGE THIS WEEKEND.

&&

.AVIATION...

RAIN IS DIMINISHING OVER THE CENTRAL PART OF THE FCST AREA AND FIRING
UP IN THE FAR SW AND TO THE SOUTH OF THE FA WHERE ATMOSPHERE IS
UNSTABLE. AMONG TAF SITES THINK DAN HAS THE BEST CHC OF TSTMS THIS
AFTN...BUT REALLY THINK IT WILL BE SOUTH OF THERE.

NEXT DECENT CHC OF CONVECTION IS LATE TONIGHT IN THE WEST AS
SIGNIFICANT FRONTAL BNDRY PRESSES SOUTH. UPSLOPE NW FLOW WILL
ENHANCE CHCS OF TSTMS ON THE WESTERN SLOPES...AND LIKE TODAY LIMIT
CONVECTION ELSEWHERE THRU 18Z TMRW.
