AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 145 PM EDT TUE AUG 26 2014 .UPDATE... THE LONG TERM SECTION HAS BEEN UPDATED BELOW. && .SYNOPSIS... ISSUED AT 225 AM EDT TUE AUG 26 2014 A VERY WARM AND HUMID AIR MASS WILL REMAIN IN PLACE OVER CENTRAL INDIANA THE NEXT FEW DAYS. THIS IN COMBINATION WITH A SLOWLY MOVING COLD FRONT FRONT THE NORTH MAY RESULT IN SHOWERS AND THUNDERSTORMS EACH DAY. LATE THIS WEEK A FRONTAL BOUNDARY IS EXPECTED TO BE LINGERING ACROSS CENTRAL INDIANA THROUGH THE LABOR DAY WEEKEND. ALTHOUGH THE FRONTAL BOUNDARY WILL COOL TEMPERATURE BACK TOWARD SEASONAL NORMALS...IT WILL KEEP CHANCES FOR SHOWERS AND THUNDERSTORMS IN THE FORECAST EACH DAY THROUGH THE HOLIDAY WEEKEND. && .NEAR TERM /REST OF TODAY/... ISSUED AT 959 AM EDT TUE AUG 26 2014 SATELLITE AND OBSERVATIONS SHOW ALTOCUMULUS CASTELLANUS ACROSS THE AREA SHOWING SOME MID LEVEL INSTABILITY. RADAR SHOWS SHOWERS POPPING UP IN THIS AREA IN MADISON COUNTY. MEANWHILE SCATTERED THUNDERSTORMS CONTINUE TO DEVELOP ACROSS NORTHERN INDIANA. HAVE EXPANDED SLIGHT CHANCE POPS SOUTH THIS MORNING TO ACCOUNT FOR THE SHOWERS POPPING UP. OTHERWISE MADE NO SIGNIFICANT CHANGES TO POPS AT THIS TIME AS NORTHERN FORECAST AREA STILL LOOKS TO HAVE BEST CHANCES FOR STORMS TODAY. STORM PREDICTION CENTER HAS PLACED OUR AREA IN A SEE TEXT SO WILL CONTINUE TO WATCH DEVELOPMENT CLOSELY. FOR NOW HAVE MADE NO SIGNIFICANT CHANGES TO TEMPERATURES BUT WILL WATCH TO SEE IF THEY NEED ADJUSTED DUE TO ANY PRECIPITATION. PREVIOUS DISCUSSION FOLLOWS... SURFACE ANALYSIS EARLY THIS MORNING SHOWS HIGH PRESSURE IN PLACE OVER THE APPALACHIANS. A WEAK COLD FRONT WAS FOUND ACROSS CENTRAL WISCONSIN...STRETCHING SW ACROSS SE IOWA TO CENTRAL KANSAS. LIGHT EASTERLY FLOW WAS IN PLACE ACROSS CENTRAL INDIANA...HOWEVER...EARLIER CONVECTION HAS LEFT SEVERAL BOUNDARIES LINGERING ACROSS THE FORECAST AREA LATE TONIGHT. DEW POINTS ACROSS THE AREA REMAINED VERY MOIST...HOLDING IN THE MIDDLE AND UPPER 60S. MAIN FORECAST CHALLENGE TODAY WILL BE POPS. GFS DEPICTS THE RIDGE WITHIN THE UPPER FLOW SAGGING SOUTHWARD TOWARD AND ALLOWING THE FLOW ALOFT TO BECOME A BIT MORE ZONAL TO NWERLY DURING THE COURSE OF THE DAY. BEST AREA FOR CONVECTIVE DEVELOPMENT WILL BE TO THE NORTHWEST...ALONG THE FRONTAL BOUNDARY...HOWEVER AS WE SAW ON MONDAY PROPAGATION SUGGESTS THAT ANY CONVECTION THAT DEVELOPS MAY HAVE THE ABILITY TO PROPAGATE SE INTO OUR MOISTURE RICH AIR AND CONDITIONALLY UNSTABLE AIR. FORECAST SOUNDINGS ALSO SHOW CONVECTIVE TEMPERATURES NEAR 90...WHICH WE FINALLY REACHED...AND PLENTY OF CAPE WITH VALUES OVER 2500 J/KG. THUS WILL INCLUDE LOW CHCS FOR POPS THIS AFTERNOON...WITH BEST POPS FOUND ACROSS THE NORTHERN PARTS OF THE FORECAST AREA...CLOSEST TO THE LIKELY PROPAGATION AREA FROM CONVECTION UPSTREAM. WITH A SIMILAR AIR MASS IN PLACE ACROSS THE FORECAST AREA TODAY WILL TREND TOWARD PERSISTENCE FOR HIGHS. && .SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/... ISSUED AT 225 AM EDT TUE AUG 26 2014 GFS AND NAM DEPICT THE UPPER FLOW BECOMING MORE NORTHWESTERLY DURING THIS PERIOD...ALLOWING SEVERAL SHORT WAVE TO PUSH OUT OF THE UPPER MIDWEST TOWARD CENTRAL INDIANA. MEANWHILE AT THE SURFACE...THE FRONTAL BOUNDARY PREVIOUSLY MENTIONED WILL ALSO SAG SOUTHWARD TO NORTHERN INDIANA BY WEDNESDAY...AND THEN STALL ACROSS CENTRAL INDIANA ON THURSDAY. FORECAST SOUNDINGS THROUGH THURSDAY SHOW LITTLE IN THE WAY OF CHANGE AS THEY REMAIN MOIST THROUGH THURSDAY WITH REACHABLE CONVECTIVE TEMPERATURES AND CAPE AVAILABLE. CONFIDENCE REMAINS LOW IN ANY SPECIFIC SHORT WAVE THROUGH THURSDAY...HOWEVER PLENTY OF INGREDIENTS REMAIN CONSTANT THROUGH THE PERIOD. THOSE INGREDIENTS BEING...THE VERY MOIST AIR MASS...DAYTIME HEATING LEADING TO INSTABILITY AND THE BREAKDOWN OF THE RIDGE AND SAGGING COLD FRONT TOWARD CENTRAL INDIANA. THUS WILL NEED TO CONTINUE DAILY POPS THROUGH THURSDAY NIGHT...FOCUSING HIGHEST POPS DURING THE MAX HEATING HOURS OF THE AFTERNOON AND EVENING. OVERALL...TEMPERATURES WILL COOL SLIGHTLY THROUGH THE PERIOD AS THE FRONTAL BOUNDARY TO THE NORTH SLOWLY SAGS SOUTHWARD ACROSS THE FORECAST AREA. WILL TREND LOWS AT OR ABOVE GUIDANCE GIVEN THE MOIST DEW POINTS AND MINIMAL ADVECTION. AS FOR HIGHS WILL TREND WARMER THAN GUIDANCE ALSO. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... ISSUED AT 145 PM EDT TUE AUG 26 2014 MAIN FOCUS REGARDING THE LONG TERM FORECAST WILL BE ON POPS AS ENSEMBLES AND DETERMINISTIC MODELS CONTINUE TO ADVERTISE AN UPPER TROUGH LIFTING NORTHEAST ACROSS THE LOWER GREAT LAKES ON SUNDAY FOLLOWED BY ANOTHER TROUGH ACROSS ROUGHLY THE SAME AREA IN THE TUESDAY TO WEDNESDAY TIME FRAME. MEANWHILE...LIGHT SOUTHERLY FLOW FLOW WILL DOMINATE AT THE LOWER LEVELS WHICH SHOULD KEEP IT WARM AND HUMID. REGIONAL BLEND TEMPERATURES REFLECT THIS WELL WITH NORMAL TO SLIGHTLY ABOVE NORMAL TEMPERATURES FOR MOST OF THE PERIOD. && .AVIATION /DISCUSSION FOR THE 261800Z TAF ISSUANCE/... ISSUED AT 1220 PM EDT TUE AUG 26 2014 SCATTERED AFTERNOON AND EVENING THUNDERSTORMS EXPECTED IN THE VICINITY OF IND AND LAF AS A COLD FRONT SLIDES SOUTHEAST TO CENTRAL INDIANA THIS AFTERNOON OR TONIGHT BEFORE STALLING. CONFIDENCE ON EXACTLY WHERE IT WILL STALL IS LOW AND THUS CONFIDENCE IN WIND DIRECTION. HOWEVER...WINDS WILL BE LESS THAN 10 KNOTS AWAY FROM STORMS ANYWAY. FLYING CONDITIONS SHOULD BE VFR WITH ONLY SCATTERED AFTERNOON VFR CU AT BEST EXCEPT MVFR OR WORSE IN HEAVIER THUNDERSTORMS. CONFIDENCE IS ONLY HIGH ENOUGH FOR VCTS AT IND AND LAF THROUGH TONIGHT. THUNDERSTORM COVERAGE SHOULD INCREASE A BIT WEDNESDAY AFTERNOON WITH CHANCES ALSO AT HUF AND BMG. HOWEVER...WILL GO WITH VCTS BEING NEAR 24 HOURS OUT. FOG WILL DEPEND ON THE DEGREE OF CONVECTIVE DEBRIS TONIGHT. FOR NOW WILL JUST GO WITH A PERIOD OF OVERNIGHT MVFR AND ADJUST AS THE TIME GETS CLOSER. && .IND WATCHES/WARNINGS/ADVISORIES...
