Area forecast discussion, Apr 30, 11:15 AM EST, 46 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 1215 PM EDT MON APR 30 2007 .UPDATE... DIFFUSE BOUNDARY STRETCHING FROM NORTHWEST TO SOUTHEAST ACROSS CENTRAL PORTION OF FORECAST AREA HAS BEEN ABLE TO GENERATE SOME SHOWERS AND A FEW THUNDERSTORMS THIS PAST HOUR. BEST FORCING WELL NORTH BUT ENOUGH LIFT AND MOISTURE CONVERGENCE BEING GENERATED NEAR FRONT TO SUSTAIN ISOLATED TO SCATTERED SHOWERS AND A FEW THUNDERSTORMS THIS AFTERNOON. BEST MOISTURE AND BAROCLINIC ZONE LIFT NORTHEAST THIS AFTERNOON PER LATEST 12Z NAM AND GFS. LOW LEVELS INITIALLY VERY DRY IN THE NORTHEAST BUT UPSTREAM CONVECTION MAY BE ABLE TO SLIDE SOUTHEAST ALONG FRONTAL BOUNDARY. THEREFORE INCLUDED ALL AREAS NORTHEAST OF 16Z BOUNDARY POSITION WITH CHANCE POPS THIS AFTERNOON. && .SHORT TERM...

MAIN FORECAST HIGHLIGHTS THROUGH IN THE LONG TERM ARE COLD FRONT PUSHING THROUGH THE REGION ON TUESDAY FOLLOWED BY COOLER AND DRIER WEATHER AS SFC HIGH PRESSURE PARKS OVER THE REGION. TUESDAY...COLD FRONT WILL PUSH THROUGH THE REGION AND BRING THE CHANCE FOR SHOWERS AND THUNDERSTORMS. MODELS ARE FINALLY AGREEING ON THE TIMING OF UPPER WAVE AND ASSOCIATED SFC LOW. HAVE INCREASE POPS TO LIKELY IN EASTERN AND SOUTHEASTERN ZONES WITH MODELS FAVORING AFTERNOON FRONTAL PASSAGE THERE. MAIN UPPER LEVEL WAVE AND SUPPORT WILL PASS TO THE NORTHEAST OF THE CWA...BUT SHARP FRONTAL ZONE...INDICATED BY STRONG TEMP/DEWPOINT/WIND GRADIENT...SHOULD PROVIDE ENOUGH FORCING TO TRIGGER A LINE OF THUNDERSTORMS GIVEN GOOD INSTABILITY. WRF AND MAV BOTH HINT AT UPPER 50S TO LOWER 60S DEWPOINTS...WHICH WOULD ELEVATE CAPE VALUES IN THE 1500-2500 J/KG RANGE DEPENDING ON AMOUNT OF SOLAR HEATING. THIS COUPLED WITH 0-6 KM BULK SHEAR VALUES OF 35 TO 45 KNOTS WOULD SUPPORT A FEW SEVERE THUNDERSTORMS...ESPECIALLY IN SOUTHEASTERN ZONES WHERE BEST UPPER DYNAMICS AND LL THERMODYNAMICS OVERLAP. KEY THIS EVENT WILL BE TIMING OF FRONT. MOST LIKELY CHANGE TO FRONTAL TIMING WOULD BE A FASTER FROPA...DUE TO UPPER WAVES LOCATION IN FAST WESTERLY FLOW. THIS WOULD TREND ALL POPS FARTHER SOUTH AND EAST...DIMINISHING SEVERE THREAT IN CWA. MUCH COOLER AND DRIER AIR WILL ADVECT INTO THE REGION BEHIND THE COLD FRONT. ECMWF IS THE COOLEST MODEL PROGGING H85 TEMPS DOWN TO 3 C BY WED AFTERNOON OVER NORTHERN ZONES. HAVE TRENDED IN THE MID RANGE MORE IN LINE WITH THE GFS. THIS WOULD BRING SLIGHTLY BELOW NORMAL TEMPS TO THE REGION WED. REGION WILL REMAIN UNDER THE INFLUENCE OF SFC HIGH PRESSURE AS UPPER HEIGHT FIELD WILL FEATURE SHARP RIDGING OVER THE CENTRAL US. GFS AND ECMWF BOTH SHIFT THIS RIDGE EAST SOME EACH DAY...WITH THE GFS BEING MORE AGGRESSIVE. HAVE ADJUSTED TEMPS FOR THIS...ALLOWING A SLIGHT INCREASE IN HIGHS EACH DAY. AS FOR PRECIPITATION...WILL LEAVE FORECAST DRY WITH NO STRONG PRECIP SIGNALS IN THE MODELS AT THIS TIME. OVERALL...LOOK FOR A TREND TO SLIGHTLY BELOW NORMAL MID NEXT WEEK WITH GRADUALLY WARMING TO AT OR ABOVE NORMAL INTO NEXT WEEKEND. EXPECT MOSTLY CLEAR SKIES WITH FAVORED UPPER LEVEL SINK REGION CENTERED OVER THE AREA WED THROUGH FRIDAY.
