AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 320 PM EDT FRI JUL 15 2005 .SHORT TERM... TONIGHT AND SATURDAY CONVECTION CONTINUES TO DEVELOP ACROSS SOUTHEAST MICHIGAN THIS AFTERNOON. CAPES ACROSS THE CWA ARE A LITTLE HIGHER THAN THE PAST TWO DAYS WITH LAPS INDICATING 2000 TO 2500 J/KG OF CAPE OVER MOST OF SOUTHEAST MICHIGAN. THIS CONVECTION WILL DECREASE WITH THE LOSS OF DIURNAL HEATING 00Z TO 02Z. THERE WILL BE A LULL IN THE ACTIVITY LATE THIS EVENING AND FOR PART OF THE OVERNIGHT. BY ABOUT 06Z...MOISTURE AT ALL LEVELS STARTS TO INCREASE. THERE IS ALSO A WEAK WAVE THAT WILL ESTABLISH A SHEAR AXIS AND DEFORMATION AXIS ACROSS THE CWA. FINALLY...THERE IS ALSO AN INCREASE IN LOW LEVEL CONVERGENCE LATE TONIGHT TOO. THIS SHOULD BE ENOUGH TO KEEP SCATTERED SHOWERS AND POSSIBLY A THUNDERSTORM IN THE FORECAST THE ENTIRE NIGHT. QUITE A BIT MORE MOISTURE EXPECTED TO BE OVER SOUTHEAST MICHIGAN ON SATURDAY. THAT SHEAR AXIS AND DEFORMATION AXIS WILL ALSO BE OVER THE REGION AND THERE WILL CONTINUE TO BE WEAK LOW LEVEL CONVERGENCE. MAY ALSO BE A LITTLE UPPER DIVERGENCE ASSOCIATED WITH A WEAK JET MAX THAT DEVELOPS ON THE SOUTH SIDE OF THE OLD CIRCULATION OF DENNIS ON SATURDAY. SOUTHEAST MICHIGAN DOES GET INTO THE LEFT FRONT EXIT REGION OF THIS SMALL JET MAX. WITH ALL OF THE CLOUDS HOWEVER...CAPES WILL ONLY REACH AROUND 1500 J/KG. THIS SHOULD SET UP FOR NUMEROUS SHOWERS ON SATURDAY...BUT EXPECT THE THUNDERSTORMS TO BE MORE SCATTERED WITH LESS INSTABILITY DUE TO LESS AVAILABLE SUNSHINE. WITH CURRENT DEWPOINTS...WILL GO WITH THE GUIDANCE NUMBERS FOR LOWS WHICH ARE AROUND 70. AIR MASS FOR SOUTHEAST MICHIGAN IS COMING FROM NORTH AND CENTRAL OHIO. TEMPS THERE HAVE MADE IT EASILY INTO THE LOW AND MID 80S. THEREFORE WILL GO TOWARD THE GFS GUIDANCE TEMPS WHICH ARE IN THE MID 80S FOR MOST OF THE CWA. && .LONG TERM...SATURDAY NIGHT THROUGH FRIDAY SATURDAY NIGHT THROUGH MONDAY...GFS/NAM IN GENERAL AGREEMENT ON NORTHEAST PROGRESSION OF DENNIS REMNANTS...ALTHOUGH THE GFS TRACK IS A LITTLE MORE COHERENT AND SLIGHTLY SLOWER. WILL SEE PLENTY OF CLOUD COVER CARRY OVER INTO SUNDAY MORNING...BUT ANTICIPATE TEMPERATURES TO CLIMB INTO THE UPPER 80S AGAIN...AS TEMPS IN THE OHIO VALLEY TODAY IN BKN/OVC CLOUD COVER MADE IT INTO THE LOWER TO MID 80S. WILL BOOST QPF TOTALS FOR SUNDAY AS WELL...IN ANTICIPATION OF A LITTLE SLOWER NORTHEAST TRACK...WILL ALSO ADD CHC POPS FOR SUNDAY EVENING FAR EAST TO COVER ANY LINGERING CONVECTION. WILL KEEP QPF TOTALS BELOW .20 INCHES THOUGH AS SOME MID LEVEL MOISTURE BEGINS TO STRIP OUT IN THE AFTERNOON. NOT MUCH RECOVERY TIME BEFORE CONVECTION FIRES AGAIN...NORTHERN U.S. TROF TO MOVE INTO THE WESTERN GREAT LAKES MONDAY...WITH CHANCE FOR ORGANIZED SEVERE CONVECTION OVER SOUTHEAST LOWER BY MONDAY EVENING. MODELS INDICATE RRQ OF 300 MB JET TO POSITION OVER THE CENTRAL GREAT LAKES BY MONDAY EVENING. IN ADDITION GOOD SHOT OF THETA-E ADVECTION AHEAD OF FRONT...AND MID LEVEL JET APPROACHING THE LOWER GREAT LAKES TO INCREASE SHEAR PROFILE. 12Z RUNS ALSO INDICATE POSSIBILITY OF DRY SLOT WORKING A LITTLE EAST OF THE COLD FRONT. CAPES COULD BE HELD DOWN A LITTLE THOUGH IF UPSTREAM DEBRIS MOVES IN MONDAY MORNING...WHICH THE NAM IS HINTING AT. ONCE AGAIN TEMPERATURES WILL BE UNIFORM THROUGH THE PERIOD...WITH 850 MB TEMPS STAGNANT AROUND 18C AND SURFACE DEW POINTS RUNNING AROUND 70. TUESDAY THROUGH FRIDAY...MEDIUM RANGE MODELS CONTINUE TO BE IN GOOD AGREEMENT THROUGH THE PERIOD WITH FIRST TROF COMING THROUGH EARLY TUESDAY...THEN BERMUDA HIGH BUILDING BACK ACROSS THE OHIO VALLEY AND GREAT LAKES REGION. GFS ENSEMBLE MEMBERS IN GOOD AGREEMENT IN REGARD TO PUSHING THE NORTHERN STREAM WELL NORTH OF THE GREAT LAKES WITH STRONG AND PERSISTENT RIDGING BUILDING BACK IN. MODELS BRING COLD FRONT THROUGH EARLY TUESDAY NOW...BUT STILL A CHANCE FOR SEVERE CONVECTION MONDAY EVENING/NIGHT WITH GOOD THETA-E ADVECTION AHEAD OF FRONT AND GOOD SHEAR POTENTIAL WITH MID LEVEL JET APPROACHING THE LOWER GREAT LAKES. REMAINDER OF THE EXTENDED PERIOD LOOKS DRY WITH ONLY WEAK RETURN FLOW THURSDAY AND FRIDAY AS BERMUDA HIGH EXTENDS WESTWARD ACROSS THE LOWER GREAT LAKES AGAIN. THE BERMUDA HIGH ALSO SHUNTS THE NEXT WARM FRONT WELL NORTH OF THE REGION...POSITIONING OVER THE NORTHERN GREAT LAKES. POTENTIAL FOR MCS DEVELOPMENT ALONG THIS FRONT...BUT TO SOON TO DETERMINE IF CONVECTION WILL TRACK SOUTHEAST OVER THE CWA OR PROPAGATE OFF TO THE EAST. WILL INCREASE TEMPS TO NEAR 90 FOR THURSDAY AND FRIDAY WITH POTENTIAL FOR PLENTY OF SUN AND LOW RH AIRMASS. && .AVIATION...ISSUED AT 135 PM AGAIN CONVECTION A BIT PART OF THE TAFS THIS FORECAST. EXPECT CURRENT CONVECTION TO GO TO AROUND 00Z...WITH FNT AND MBS ENDING A LITTLE LATER THAN THE DETROIT AREA TAFS. THEN TONIGHT AS MOISTURE ADVECTION CONTINUES THROUGH THE NIGHT AT NEARLY ALL LEVELS...EXPECT THE AC FROM THIS EVENINGS CONVECTION TO COVER MOST OF SOUTHEAST MICHIGAN. AIR MASS IS COMING FROM NORTHERN OHIO...AND THERE WERE SOME LOWER CIGS AND VISBYS DUE TO FOG. SO DID LOWER TO SOME MVFR SIGS AND IFR VISBYS. FINALLY THERE IS A WEAK SHORTWAVE THE MOVES INTO THE REGION AND A DEFORMATION AXIS SETS UP OVER SOUTHEAST MICHIGAN. COMBINE THIS WITH THE INCREASING MOISTURE AND WILL HAVE SOME PROB30 AND TEMPOS IN THE TAFS WITH LOWER CIGS FOR SATURDAY MORNING. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE. LAKE ST CLAIR...NONE. MI WATERS OF LAKE ERIE...NONE. && AVIATION...RBP SHORT TERM...RBP LONG TERM....GSS
