Area forecast discussion, Jul 1, 7:01 PM EDT, 2 hours 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON WV 701 PM EDT MON JUL 1 2013 .SYNOPSIS... UPPER LOW...CENTERED NEAR EVANSVILLE IN...WILL SLOWLY DRIFT NORTHWEST THROUGH LATE THIS WEEK. THIS WILL ALLOW DEEPER MOISTURE CURRENTLY ALONG EAST COAST TO CREEP WEST WITH TIME. && .NEAR TERM /THROUGH TUESDAY/... 7 PM UPDATE...THINGS BECOMING CLEARER AS CONVECTION ORGANIZES AND HI RES MODELS CATCH ON TO IT. APPEARS SHORT WAVE AXIS WITH WELL ORGANIZED BAND OF CONVECTION EXTENDING EASTERN KENTUCKY SOUTHWARD THRU EASTERN TENNESSEE WILL LIFT NORTH NORTHEASTWARD ACROSS OUR AREA THIS EVENING INTO EARLY TONIGHT. ALSO...BAND OF CONVECTION RIDING ALL ALONG OUR MOUNTAINS WILL LIFT NORTHWARD AND FEED INTO THIS SHORT WAVE ACTION. BOTTOM LINE IS...LOOKS LIKE A WET EVENING AS EVERYTHING LIFT UP...AND HAVE RAISED POPS MOSTLY TO CAT. AFTER 06Z...THINGS QUIET AS SYSTEM EXITS TO THE NORTH AND EAST...WITH FOG FORMATION LATER TONIGHT. PREVIOUS DISCUSSION... LATEST WV IMAGERY SHOWS UPPER LOW IS CURRENTLY CENTERED NEAR EVANSVILLE IN. WHILE TOUGH TO SEE ON SATELLITE...IT APPEARS THERE MAY BE A SHORTWAVE ROTATING AROUND THIS LOW...AS THUNDERSTORMS ARE DEVELOPING ACROSS PORTIONS OF CENTRAL/EASTERN KY...TN AND WESTERN PORTIONS OF VA AND NC. SPC RECENTLY ISSUED A SWOMCD INDICATING A SVR TSTM WATCH MAY BE NEEDED FOR SOME OF OUR VA AND NE KY COUNTIES AS THE SHORTWAVE AND ASSOCIATED STORMS MOVE N/NE WITH TIME. EXPECT STORMS TO DECREASE IN INTENSITY AND AREAL COVERAGE AFTER 04Z AS THE SHORTWAVE MOVES NORTH AND THE AIRMASS BECOMES LESS UNSTABLE WITH THE LOSS OF SUNSHINE. MODELS SUGGEST LOW-LEVEL FLOW WILL BE QUITE LIGHT OVERNIGHT. HOWEVER...THERE SHOULD BE LIGHT SOUTHEAST WINDS INTO THE MOUNTAINS WHICH SHOULD KEEP SOME CHANCE OF STORMS. OTHER THAN THE STORMS...AM A LITTLE CONCERNED ABOUT THE FORMATION OF DENSE FOG AS MUCH OF THE REGION IS QUITE WET AND THERE SHOULD SOME BREAKS IN THE CLOUDS...ESPECIALLY ACROSS THE LOWLAND COUNTIES. WILL NOT CURRENTLY HIT THE FOG TOO HARD TONIGHT AS UNCERTAINTY IS STILL QUITE HIGH. SOUTHWEST UPPER FLOW IS EXPECTED TO PERSIST ON TUESDAY. COMBINATION OF CONTINUED SOUTHEAST LOW-LEVEL WINDS AND ANY WEAK SHORTWAVE SHOULD RESULT IN THE DEVELOPMENT OF SHOWERS AND STORMS..ESPECIALLY IN THE AFTERNOON. EXPECT THE STORMS TO BE MOST NUMEROUS IN THE MOUNTAINS. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... UPPER LOW WILL RETROGRADE MID WEEK WITH UPPER HIGH PUSHING WESTWARD ONTO THE EAST COAST. MOISTURE WILL INCREASE ACROSS THE REGION AS THE LOW RETROGRADES WEST...WITH PW VALUES RISING TO 1.7 TO 1.8 INCHES MID WEEK. THIS IN COMBINATION WITH SEVERAL UPPER DISTURBANCES WILL KEEP A CHANCE OF SHOWERS AND STORMS IN THE FORECAST...WITH HEAVY RAIN AT TIMES. ELECTED TO ADD HEAVY RAIN WORDING TO THE FORECAST FOR WEDNESDAY AND THURSDAY TIME FRAME...AND A FLASH FLOOD WATCH MAY BE NECESSARY FOR PARTS IF NOT ALL OF THE CWA DURING THIS TIME PERIOD. THURSDAY...MODELS ARE PRETTY CONSISTENT WITH A SIGNIFICANT WAVE MOVING NORTH ACROSS WESTERN ZONES...CREATING AN AREA OF HEAVIER RAIN ACROSS SOUTHEAST OHIO AND EASTERN KY. RAISED POPS ACROSS THESE AREAS TO LIKELY FROM PREVIOUS FORECAST. && .LONG TERM /FRIDAY THROUGH MONDAY/... BERMUDA HIGH WILL CONTINUE TO RETROGRADE WEST TOWARDS THE EAST COAST...WHICH SHOULD RESULT IN SOMEWHAT DRIER WEATHER...PARTICULARLY ACROSS THE EASTERN ZONES. HOWEVER...WITH THE WARM HUMID AIR MASS IN PLACE...AND NUMEROUS DISTURBANCES EXPECTED TO CONTINUE TO MOVE THROUGH THE REGION...KEPT CHANCES OF SHOWERS AND THUNDERSTORMS IN THE FORECAST...WITH MAINLY A DIURNAL TREND. HOWEVER...OVERALL COVERAGE SHOULD BE LESS THAN IN PREVIOUS DAYS. WITH BUILDING HEIGHTS BY WEEKEND AS THE HIGH PUSHES FARTHER WESTWARD...EXPECT TEMPERATURES TO ONCE AGAIN RISE ABOVE NORMAL. && .AVIATION /00Z MONDAY THROUGH SATURDAY/... 00Z TUESDAY THRU 00Z WEDNESDAY... SHORT WAVE WITH ORGANIZED BAND OF CONVECTION...WITH EMBEDDED THUNDER...WILL LIFT NORTH NORTHEAST ACROSS THE AREA BETWEEN 00Z AND 06Z. EXPECT MVFR TO LOCALLY IFR IN HEAVIER CONVECTION THRU 06Z...OTHERWISE VFR CEILINGS. AFTER 06Z...WITH THE WET GROUND EXPECTED...EXPECT IFR FOG ALONG RIVERS AND IN VALLEY AFFECTING THE MAJOR TERMINALS. AFTER 13Z...IMPROVING RAPIDLY TO VFR CEILINGS WITH SCATTERED CONVECTION AGAIN DEVELOPING AFTER 17Z. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z WEDNESDAY... FORECAST CONFIDENCE...MEDIUM. ALTERNATE SCENARIOS: MIMIC OF ORGANIZED BAND OF CONVECTION EARLY TONIGHT MAY VARY BY AN HOUR OR TWO. DEVELOPMENT AND EXTENT OF FOG DEPENDS GREATLY ON OCCURRENCE OF RAINFALL. EXPERIMENTAL TABLE OF FLIGHT CATEGORY OBJECTIVELY SHOWS CONSISTENCY OF WFO FORECAST TO AVAILABLE MODEL INFORMATION: H = HIGH: TAF CONSISTENT WITH ALL MODELS OR ALL BUT ONE MODEL.
