Area forecast discussion, Apr 28, 3:25 PM EDT, 49 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON WV 325 PM EDT MON APR 28 2014 .SYNOPSIS... A WARM FRONT LIFTS NORTH TODAY. ADDITIONAL ROUNDS OF SHOWERS AND THUNDERSTORMS EXPECTED TONIGHT INTO WEDNESDAY...BEFORE WEAKENING COLD FRONT FINALLY CREEPS THROUGH. && .NEAR TERM /THROUGH TONIGHT/... THE THUNDERSTORMS ASSOCIATED WITH THE WARM FRONT LIFTING THROUGH THE AREA TODAY HAVE TAPERED OFF BUT NEW ONES ARE BEGINNING TO FIRE IN THE WARM MOIST UNSTABLE AIR TO THE SOUTH. WILL NEED TO KEEP WATCHING THIS AREA AS THERE IS GOOD INSTABILITY AND SHEAR. INITIALLY THE MORE UNSTABLE AIR SPREADS INTO EASTERN KENTUCKY AND SOUTHWEST VIRGINIA BUT LIFTS NORTH INTO SOUTHWEST WEST VIRGINIA AND SOUTHEAST OHIO LATER THIS AFTERNOON BECOMING CENTERED OVER THE TRI STATE AREA THIS EVENING. THUNDERSTORMS WILL TAPER BACK OFF TO MORE ISOLATED TO SCATTERED COVERAGE THROUGH THE OVERNIGHT HOURS. THE BIG UPPER LOW CENTERED OVER THE MIDWEST GRADUALLY SHIFTS GRADUALLY SHIFTS A BIT EAST OVERNIGHT BRINGING THE NEXT MORE ORGANIZED BAND OF SHOWERS AND THUNDERSTORMS OVER THE AREA TUESDAY MORNING. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... PLENTY OF THREATS ACCOMPANY AN UPPER LEVEL LOW AS IT PARKS OVER THE UPPER MIDWEST AND ROTATES WAVES OF ENERGY AROUND IT ON A 100 PLUS KT JET STREAM. KEPT FORECAST WET AND STORMY. TIMING OF THESE WAVES IS QUESTIONABLE DUE TO CHAOTIC NATURE OF THESE TYPES OF SYSTEMS. THE BEST TIMING FOR THE TWO WAVES DURING THIS PERIOD IS THE FIRST PASSES TUESDAY MORNING AROUND 8 AM AND THE SECOND PASSES AROUND THE SAME TIME ON WEDNESDAY MORNING. THE MAIN COLD FRONT ASSOCIATED WITH THIS STORM MOVES THROUGH ON TUESDAY MORNING BRINGING A THREAT OF THUNDERSTORMS. SOME OF THESE STORMS MAY BE STRONG GIVEN THE 0-3 KM BULK SHEAR IN THE REGION RANGES BETWEEN 30 AND 50 KT. LOW CAPE WILL LIKELY INHIBIT MUCH OF THIS LINE FROM BECOMING SEVERE...BUT WILL HAVE TO KEEP AN EYE ON IT. ANOTHER THREAT TO KEEP AN EYE ON IS FLOODING POTENTIAL AS THE SECOND WAVE MOVES THROUGH ON WEDNESDAY MORNING. RIGHT NOW...IT DOES NOT APPEAR TO BE TOO MUCH OF A CONCERN AS THE WAVES MOVE THROUGH AT A FAIRLY GOOD CLIP...BUT ALL IT TAKES IS ONE GOOD THUNDERSTORM TO PRIME AN AREA. MODEL CONSENSUS GIVES PRECIP ACCUMULATIONS AROUND AN INCH AND A HALF FOR THE AREA...GIVEN THE FACT THAT WE ARE STARTING OUT QUITE DRY...IT SHOULD TAKE QUITE A BIT OF RECITATION TO CAUSE FLOODING. && .LONG TERM /THURSDAY THROUGH MONDAY/... LARGE LOW PRESSURE SYSTEM SFC AND ALOFT IS THE MAIN DRIVING FORCE IN THE EXTENDED...GRADUALLY LOSING ITS GRIP ON THE AREA AS IT LIFTS THROUGH EASTERN CANADA NEXT WEEKEND. THE SYSTEM WILL BE AN AGING...SPIRALING OCCLUSION BY THE START OF THE EXTENDED PERIOD...00Z THU. THE OCCLUSION MOVES THROUGH THE FCST AREA WED NT...BRINGING SHOWERS EWD ACROSS THE AREA. THE INSTABILITY AXIS SHOULD ALREADY BE OVER EASTERN PORTIONS OF THE FCST AREA AS OF 00Z THU...AND QUICKLY MOVES E AND WANES AFTER SUNSET. THE REMAINDER OF THE PERIOD IS CHARACTERIZED BY COOLER WEATHER WITH SHOWERS TIED TO THE DIURNAL CYCLE...AND SMALLER UPPER LEVEL DISTURBANCES WITHIN THE FLOW AROUND THE LARGER SYSTEM...ONE THU AND ONE SAT. FOR SAT...SFC HEATING BENEATH THE COOL AIR ALOFT MAY CREATE JUST ENOUGH INSTABILITY FOR AFTERNOON THUNDER,. BY SUN OR SUN NT...A DISTINCTLY SEPARATE DISTURBANCE MAY BE APPROACHING...AS THE LARGE LOW PRESSURE SYSTEM PULLS AWAY. LITTLE CHANGE NEEDED TO TEMPERATURES...BLENDING IN MORE OF WPC AND MOSGUIDE WITH TIME. HAVE VALUES A LITTLE BELOW NORMAL WITH 60S BY DAY AND 40S BY NT...SOME 40S AND 30S RESPECTIVELY IN THE MOUNTAINS...JUST COLD ENOUGH FOR A LITTLE WET SNOW ACROSS THE HIGHER TERRAIN LATE SAT NT INTO EARLY SUN MORNING. HAVE HIGHS A LITTLE HIGHER THAN PREVIOUS FRI. BY SAT...THE ECMWF DIVERGES WITH FLOW BACKING MORE TO THE S FOR A MILDER SOLN THAN THE GFS...CLOSER TO THE COOLER SIDE FOR NOW. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... CONDITIONS WILL REMAIN PRIMARILY VFR BRIEFLY DROPPING TO MVFR DURING BRIEF DOWNPOURS DURING STRONGER SHOWERS OR THUNDERSTORMS. THUNDERSTORM COVERAGE WILL INCREASE THIS AFTERNOON AND EVENING OVER SOUTHERN AND WESTERN AREAS AND THEN AGAIN TUESDAY MORNING AS A STRONGER MORE ORGANIZED BAND MOVES THROUGH BETWEEN 11Z WEST AND 14Z EAST. EXPECT TO SEE CONDITIONS DROP TO MVFR FOR SEVERAL HOURS AS THE TUE MORNING BAND MOVES THROUGH. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z TUESDAY... FORECAST CONFIDENCE: MEDIUM.
