Area forecast discussion, May 10, 11:23 AM EST, 1 hour 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 1223 PM EDT TUE MAY 10 2011 .UPDATE... THE AVIATION SECTION HAS BEEN UPDATED BELOW. && .SYNOPSIS... A WARM FRONT WILL STALL OUT NORTHEAST OF THE AREA TONIGHT WHILE AN UPPER RIDGE BUILDS INTO THE AREA. AN UPPER LOW WILL MOVE INTO THE AREA FOR THE WEEKEND. THE UPPER RIDGE WILL BRING WARM AIR AND LOWER CHANCES FOR RAIN...BUT COOLER CONDITIONS AND HIGHER CHANCES FOR RAIN WILL RETURN WITH THE UPPER LOW THIS WEEKEND. && .NEAR TERM /REST OF TONIGHT/... STRONG UPPER RIDGE MAKING ITS PRESENCE KNOWN AS THERE HAS BEEN NO MORE CONVECTIVE DEVELOPMENT IN THE WAKE OF THE WARM FRONTAL PASSAGE EVEN WITH AMPLE INSTABILITY. LATEST RUN OF THE RAPID REFRESH SHOWS NO PRECIP OVER ANY OF THE AREA TONIGHT AND 18Z GFS CONCURS. WITH NO DEVELOPMENT JUST UPSTREAM ON SATELLITE AND RIDGE AXIS PROGGED TO MOVE FROM JUST UPSTREAM TO DIRECTLY OVERHEAD DURING THE TONIGHT PERIOD HAVE PULLED POPS OUT FROM ALL BUT THE FAR NORTHEASTERN COUNTIES. ONLY LEFT A SLIGHT CHANCE IN THE NORTHEAST BEFORE 6Z BECAUSE OF THE VICINITY OF THE WARM FRONT. LOW TEMPERATURES IN THE MID 60S LOOK GOOD WITH DEWPOINTS CURRENTLY IN THE UPPER 60S THAT SHOULD DROP A BIT OVERNIGHT. WITH THE UPPER RIDGE OVERHEAD AND THE HIGHER DEWPOINTS THERE MAY BE SOME POTENTIAL FOR FOG. WITH WINDS STAYING LIGHT BUT NOT GOING CALM BECAUSE OF PRESSURE GRADIENT THINK THE BEST CHANCE FOR ANY FOG WILL BE IN AREAS THAT SAW SOME RAIN TODAY AND ARE NEAREST TO THE WARM FRONT...SO WILL ADD PATCHY FOG TO THE NORTHEASTERN COUNTIES. && .SHORT TERM /WEDNESDAY THROUGH SATURDAY/... THE UPPER RIDGE BEGINS TO MOVE OFF TO THE EAST WEDNESDAY AFTERNOON AND LOSE ITS INFLUENCE. WITH THE EXPECTED INSTABILITY FEEL THAT LOW POPS ARE WARRANTED ALL AREAS WEDNESDAY AFTERNOON. WITH A RELATIVELY WARM START AND SUNSHINE...HIGHS IN THE MID 80S LOOK GOOD...WHICH IS A BLEND OF MOS. THE UPPER RIDGE WILL CONTINUE TO MOVE EAST INTO FRIDAY AS THE UPPER LOW BEGINS ITS APPROACH. INSTABILITY WILL STILL BE AROUND. GIVEN THESE CONVECTION WILL HAVE A CHANCE TO DEVELOP DURING THE PERIOD...SO WENT LOW POPS INTO THURSDAY NIGHT. WENT A LITTLE HIGHER...BUT STILL CHANCE CATEGORY...ON FRIDAY WITH THE UPPER LOW GETTING CLOSER ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS LOOKS LIKELY. && .LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/... PERIOD LOOKS TO BE COOL... CLOUDY... WITH WIDESPREAD DECENT CHANCES FOR SHOWERS AND THUNDERSTORMS THROUGHOUT THE WEEKEND. UPPER LEVEL CUTOFF LOW PRESSURE SYSTEM LOOKS TO TRACK SOUTHEASTWARD FROM THE WEST OF THE OHIO VALLEY DURING THE WEEKEND AND INTO EARLY NEXT WEEK. THIS IS SUPPORTED BY BOTH ECMWF AND GFS... BUT THERE ARE SOME DIFFERENCES IN THE INTENSITY AND TRACK DURING THIS PERIOD. BY MONDAY NIGHT... THE GFS HAS THE SYSTEM STRONGER AND CENTERED OVER TENNESSEE... WHEREAS THE ECMWF HAS THE SYSTEM FURTHER SOUTH NEAR THE GULF COAST. AFTER COLLABORATING WITH OTHER OFFICES ON UNCERTAINTY WITH THE GUIDANCE... DECIDED TO USE A BLEND OF HPC AND ECMWF. LOOKS LIKE BEST CHANCE FOR THUNDERSTORMS WOULD BE SATURDAY INTO SUNDAY AS SFC LOW TRACKS SOUTHEASTWARD ALMOST DIRECTLY OVER THE AREA. TAPERED OFF PRECIP AMOUNTS AND DECREASED POPS AS THE SYSTEM DEPARTS AND HIGH PRESSURE BUILDS IN EARLY NEXT WEEK. TEMPS LOOK TO CONTINUE TRENDING DECENTLY BELOW NORMAL WITH LOWS IN THE UPPER 40S TO LOW 50S MONDAY AND TUESDAY MORNING. STUCK CLOSE TO HPC FOR WINDS. && .AVIATION /DISCUSSION FOR THE 11/06Z TAFS/... VFR CEILINGS SHOULD PREVAIL THROUGH THE TAF PERIOD. WITH LATE EVENING DEW POINTS IN THE UPPER 60S...COULD SEE SOME MVFR FROM 09Z-12Z ESPECIALLY AT HUF AND BMG WHERE THE DEW POINT DEPRESSION WAS ONLY 4 DEGREES LATE THIS EVENING. HOWEVER...WITH CIRRUS DECK MOVING IN FROM THE WEST AND NO RAIN YESTERDAY ACROSS THE TAF SITES...FOG SHOULD NOT BE WORSE THAN MVFR DESPITE LIGHT TO CALM WINDS. ISOLATED WARM SECTOR THUNDERSTORMS CAN NOT BE RULED OUT THROUGH EARLY TOMORROW AFTERNOON...BUT WITH THE ATMOSPHERE EXPECTED TO BE CAPPED...BEST CHANCE OF THUNDERSTORMS WILL BE AFTER 20Z AS UPPER RIDGE MOVES TO THE EAST OF THE TAF SITES. STILL TOO FAR OUT AND WIDESPREAD COVERAGE NOT ANTICIPATED...SO WILL ONLY GO WITH CB'S FOR NOW. WINDS WILL BE LESS THAN 10 KNOTS THROUGH THE PERIOD. && .IND WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...50/SMF/CP NEAR TERM...CP SHORT TERM...50/SMF LONG TERM....AKB AVIATION...MK
