AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 1230 PM EST WED MAY 12 2004 .AVIATION... NRN INDIANA WILL REMAIN IN THE WARM AND MOIST AIRMASS THROUGH 18Z THURSDAY. CONVECTION ALREADY FORMING AT 17Z...SO STORMS SHOULD PERSIST INTO THIS EVENING WITH DAYTIME HEATING. SHORTWAVE OVER WESTERN MO AT 17Z WILL MOVE EAST AND CONT THE CHANCE FOR SHOWERS LATE TONIGHT AND EARLY THURSDAY...SO HAVE LEFT THE CHANCE FOR SHOWERS LATE TONIGHT EARLY THURSDAY IN THE TAFS. OTHERWISE...SOUTHEAST TO SOUTH WINDS SHOULD CONTINUE WITH VFR CONDITIONS. && .PREV DISCUSSION... SHORT TERM...TODAY AND TONIGHT...SFC ANALYSIS SHOWS FRONTAL BOUNDARY OVER THE AREA HAS LIFTED NORTH OF THE CWA. AREA WILL REMAIN IN WARM SECTOR THROUGH TONIGHT. WITH NO REAL FOCUS FOR ORGANIZED CONVECTION TODAY...EXPECT JUST ISOLATED TO SCATTERED TSRA TO DEVELOP BY THIS AFTERNOON AND WILL KEEP GRIDS IN LOW CHANCE THROUGH THE AFTERNOON HOURS. UPPER LEVEL DISTURBANCE OVER LA WILL BE MAIN FEATURE TO MONITOR AS IT MOVES UP BACK SIDE OF UPPER RIDGE AND INTO THE AREA TONIGHT. GFS APPEARS A BIT OVERDONE WITH THIS FEATURE BUT EVEN ETA INDICATING ENOUGH FORCING TO ACCOMPANY IT TO SUPPORT CONVECTION LATER TONIGHT. NOT MUCH ADJUSTMENT TO CURRENT FCST THOUGH...WILL KEEP MENTION OF PRECIP IN CHANCE RANGE AND TWEAK POPS UP TO HIGH CHANCE IN THE WEST HALF. WARM AND MUGGY CONDITIONS BOTH TODAY AND TONIGHT AND WILL GO MORE TOWARD WARMER FWC/MET GUIDANCE NUMBERS. LONG TERM...THURSDAY THROUGH TUESDAY...WEAKENING WAVE WILL CONTINUE NORTHEAST INTO MICHIGAN THURS AM. WILL KEEP HIGHEST POPS IN THE AM...THEN TONE DOWN FOR THE AFTERNOON INTO THURS NGT AS NO SIGNIFICANT FOCUS EXPECTED FOR ADDITIONAL CONVECTION. ANY OUTFLOW BOUNDARY LEFT OVER COULD STIR THINGS UP DURING PEAK HEATING...BUT WILL LET LATER SHIFTS DEAL WITH THAT. MODELS STILL HAVING SOME TIMING/STRENGTH ISSUES WITH COLD FRONT FOR FRI/FRI NGT. GUIDANCE NUMBERS LEANING TOWARDS LIKELY POPS...BUT AM HESITANT TO BUMP UP TO LIKELY FOR ANY SPECIFIC PERIOD THAT FAR OUT. ALSO SOME CONCERN THAT FRONT MAY NOT MAKE IT THROUGH AS FAST AS MODELS THINK WITH SOME OF THE MED RANGE MODELS HINTING AT MAIN LONGWAVE TROUGH DEAMPLIFYING AS IT MOVES IN BY SATURDAY. FOR NOW WILL OPT FOR HIGH SCT POPS FRI/FRI NGT. AS ALREADY NOTED...AMPLITUDE OF UPPER LEVEL PATTERN WILL PLAY A BIG ROLE IN REMAINDER OF FORECAST...WITH NEXT SYSTEM POSSIBLY ARRIVING MONDAY (BIG DIFFERENCES ON TIMING AND TRACK). WILL HOLD WITH CURRENT DRY AND SEASONABLY PLEASANT WX FOR NOW. TEMP WISE...WARM TEMPS WILL REMAIN FOR THURS AS EXPECTING AT LEAST SOME SUN. FRI TEMPS LOOK TO BE COOLER WITH INCREASE IN CLOUDS/PRECIP ...WITH SOME ADDITIONAL COOLING INTO THE WEEKEND...BACK TO MORE SEASONABLE LEVELS. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE.
