AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 348 AM EDT SAT APR 22 2006 .SHORT TERM /TODAY THROUGH TONIGHT/... THE CUTOFF UPPER LOW REMAINS OVER THE WESTERN GREAT LAKES REGION THIS MORNING...AND IS PHASED WITH A STRONG SOUTHERN STREAM UPPER LOW CREATING A FULL LATITUDE TROUGH TO THE GULF COAST. LOOKING AT WATER VAPOR...THE MAIN UPPER LOW/SHORT WAVE IS BEGINNING TO LIFT NORTHEASTWARD TOWARD THE CAROLINAS...WHILE A SERIES OF WEAKER WAVES ARE CURRENTLY MOVING NORTHEAST THRU THE SOUTHERN APPALACHIANS. LOOKS LIKE THE THREAT OF HEAVY RAIN FROM BANDS OF SHOWERS/THUNDERSTORMS WILL BE IN THE MTNS INTO EARLY MORNING...AND THEN SHIFT EASTWARD AS THE MAIN UPPER LOW LIFTS THRU THE CAROLINAS AND THE BANDS OF TSTMS WILL BE LIFTING NORTHEAST THRU THE FOOTHILLS AND PIEDMONT. WILL HAVE CATEGORICAL POPS THIS MORNING IN THE WEST...AND THEN THIS AFTERNOON IN THE EAST WITH A MENTION OF HEAVY RAIN FOR ALL AREAS. WHILE LOCALLY HEAVY RAINFALL AMOUNTS OF 2 INCHES ARE POSSIBLE WHERE THERE ARE TRAINING OF CELLS...WE HAVE BEEN DRY ENOUGH THAT THIS SHOULD NOT CAUSE ANYTHING OTHER THAN MINOR RUNOFF FLOOD PROBLEMS. TIMING OF THE FRONT IS SUCH NOW THAT IT DOES NOT LOOK LIKE WE WILL HAVE MUCH HEATING BEFORE IT MOVES THRU- EVEN IN THE PIEDMONT. STILL..DYNAMICS WILL BE STRONG ENOUGH THAT WE MAY SEE A FEW STRONG STORMS WITH A POTENTIAL FOR DAMAGING WINDS OR LARGE HAIL...MAINLY NW PIEDMONT OF NC AND SOUTHSIDE VA. CLOUDS AND PRECIP WILL HOLD TEMPS DOWN TODAY- GENERALLY STAYED CLOSE TO MOS. WITH THE SURFACE LOW DEVELOPING ON THE FRONT AS THE UPPE RLOW LIFTS NE...THINK THE FRONT WILL SLOW DOWN ENOUGH THAT THERE MAY BE SOME ONGOING SHOWERS/THUNDERSTORMS INTO EARLY EVENING IN THE EASTERN PIEDMONT SECTIONS OF THE CWA...SO I RAISED POPS A BIT THROUGH 9:00 PM...OTHERWISE...JUST SOME LINGERING SHOWERS FURTHER WEST IN THE EVENING. NOT MUCH COLD ADVECTION BEHIND THIS FRONT...AND WINDS MAY DROP OFF LATE AS THE SHORT WAVE RIDGE BUILDS QUICKLY OVER THE AREA. IF IT CLEARS OVERNIGHT WE WOULD LIKELY SEE SOME FOG. I HAVE NOT PUT IT IN THE GRIDS AT THIS POINT...WILL NEED TO TAKE A CLOSER LOOK LATER ON. SHOULD BE A MILD NIGHT- KEPT LOWS CLOSE TO MOS AGAIN. && .LONG TERM /SUNDAY THROUGH FRIDAY/... A SECONDARY WEAK COOL FRONT ASSOCIATED WITH THE OLD CUTOFF LOW OVER THE WESTERN GREAT LAKES IS PROGGED TO MOVE INTO THE AREA AS THE UPPER LOW FINALLY GETS KICKED EASTWARD. THERE WILL STILL BE PLENTY OF LOW LEVEL MOISTURE...AND LAPSE RATES INCREASE A SOME OF THE COLDER AIR ALOFT WITH THE UPPER LOW BRUSHES THE CWA. CAPES INCREASE TO AROUND 1000 J/KG SUN AFT IN THE MTNS...SO I RAISED POPS TO LOW CHANCE FOR SHOWERS. SINCE THERE WILL BE A FAIRLY STRONG DOWNSLOPE WEST WIND...I DID NOT TAKE THE POPS EAST OF THE MTNS SUN AFT. THE FRONT REMAINS STNRY ORIENTED WEST-EAST ACROSS THE AREA...AND MODELS ARE SHOWING A WAVE ALONG THE FRONT MON NIGHT/TUESDAY. I LOWERED POPS SOME MON NIGHT SINCE THE FRONT APPEARS TO BE SOUTH OF MOST OF THE AREA...BUT KEPT THE HIGH POPS TUESDAY THINKING THE FRONT WILL PROBABLY MOVE BACK NORTHWARD WITH THE WAVE ALONG IT. NO CHANGES BEYOND MON NIGHT. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...NONE. NC...NONE. WV...NONE. && JJ/
