AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 344 PM EDT TUE APR 26 2011 .SHORT TERM...TONIGHT... DESPITE AN EARLY AND STRONG NWD SURGE BY THE SFC WARM FRONT WHICH PUT ALL OF SE MICHIGAN INTO THE WARM SECTOR LATE THIS MORNING AND EARLY THIS AFTN...THE BEST MOISTURE AND INSTABILITY HAS REMAINED WELL TO THE SOUTH THUS FAR. HOWEVER...CURRENT OBS/LAPSE DATA AND SHORT TERM MODEL SOLUTIONS INDICATE DEWPOINTS IN THE LOW 60S SURGING INTO NORTHERN IL ALONG CORRESPONDING TO A NOSE OF INCREASING SFC BASED INSTABILITY THIS AFTN. CURRENT SAT TRENDS INDICATE THAT THE LL CAP HAS BEGUN TO ERODE ACROSS AREA AS WIDESPREAD STRATOCU CLOUD DECK HAS BEEN REPLACED BY DEVELOPING CU FIELD. BEST CHANCE FOR SEVERE WX TODAY HAS SHIFTED TO THIS EVENING. CONVECTION WILL INITIATE ALONG A SFC COLD FRONT THIS AFTERNOON AND SHORT TERM GUIDANCE HAS COME INTO GENERAL AGREEMENT THAT INSTABILITY WILL BE MAXIMIZED THIS EVENING OVER SE MICHIGAN AS THE SFC LOW LIFTS INTO THE WESTERN GREAT LAKES. THERE IS SOME UNCERTAINTY REGARDING THE NATURE OF THE CONVECTION AS IT ENTERS THE CWA FROM THE WEST...MAINLY BECAUSE OF TIMING/DIRUNAL HEATING CONCERNS. SHOULD THE CONVECTION...WHICH WILL BE SLOW TO MOVE EASTWARD DUE TO A STRONG S-N COMPONENT OF MOTION...ARRIVE AFTER THE LOSS OF DAYTIME HEATING THE DEVELOPING NOCTURNAL INVERSION WOULD TEND KEEP THE LOW LEVELS CAPPED IN ADVANCE OF THE ADVANCING CONVECTIVE LINE AND APPROACHING COLD FRONT. PROVIDED THAT LIFT ALONG THE FRONT IS SUFFICIENTLY STRONG TO CONTINUE TO LIFT SURFACE PARCELS ABOVE THE CAP...THE EXPECTATION WOULD BE FOR A LINE OF CONVECTION WITH A SOMEWHAT DIMISHED CONVECTIVE THREAT TO ROLL THROUGH THE AREA THIS EVENING. WITH CAPE PROFILES OF 500-1000 J/KG SPREAD OVER A DEEP LAYER...NOT EXPECTING PARTICULARLY VIGOROUS UPDRAFT DEVELOPMENT AT THIS POINT REGARDLESS OF TIMING. HOWEVER...FOR ANY LOCALLY INTENSE UPDRAFTS THAT DO DEVELOP...A VEERING WIND PROFILE COMBINED WITH AMPLE SPEED SHEAR AND 0-1KM SRH VALUES RANGING FROM 150-200 AREA-WIDE WOULD BE QUITE FAVORABLE FOR THE DEVELOPMENT OF ORGANIZED CONVECTIVE STRUCTURES WITH HAIL BECOMING THE PRIMARY THREAT AS A NOCTURNAL INVERSION INHIBITS DOWNWARD MOMENTUM TRANSPORT AND THE RESULTANT WIND THREAT. THE FLY IN THE OINTMENT SO TO SPEAK IS IF THE EASTERLY COMPONENT OF THE STORM MOTIONS ARE ENOUGH TO ALLOW CONVECTION TO PROPAGATE INTO THE CWA BEFORE SURFACE BASED INSTABILITY IS LOST. IN THAT CASE...THE SEVERE THREAT WOULD INCREASE MARKEDLY WITH AN INCREASED LIKLIHOOD OF WIDER COVERAGE OF SFC BASED CONVECTION AND WIND BECOMING THE PRIMARY THREAT. IN EITHER CASE...THE THREAT OF TORNADIC DEVELOPMENT CANNOT BE RULED OUT DUE TO AVAILABLE LL ENVIRONMENTAL SHEAR AND THE POTENTIAL FOR CONVECTION TO BECOME ROOTED IN THE BOUNDARY LAYER...EVEN IN THE LATE EVENING HRS. SECONDARY FORECAST CONCERN THIS AFTN IS ONSET OF PRECIPITATION ON WED MORNING. WITH THE NAM BEING THE SIGNIFICANT OUTLIER WITH REGARDS TO THE POSITION AND STRENGTH OF THE SFC LOW...WILL FAVOR A FORECAST THAT FOLLOWS GFS/ECMWF/SREF GUIDANCE MORE CLOSELY RESULTING IN AN EARLIER ONSET OF SHRA IN THE MORNING AS ANOTHER SFC LOW LIFTS NORTH ALONG THE BOUNDARY. && .LONG TERM...WEDNESDAY THROUGH NEXT TUESDAY WATER VAPOR IMAGERY SHOWS SHORT WAVE ENERGY CURRENTLY OVER NEW MEXICO WITHIN THE BASE OF THE LONG WAVE CENTRAL US TROUGH. THE 00Z MODEL SUITE INDICATE THIS WAVE DEVELOPING A NEGATIVE TILT AS IT LIFTS NORTHEAST ACROSS THE OHIO VALLEY/GREAT LAKES REGION LATE WED AND WED NIGHT. A FAVORABLE COUPLED JET STRUCTURE WILL ALSO BE PRESENT ACROSS THIS REGION AS A 140KT UPPER JET ROUNDS THE BASE OF THE TROUGH. THIS WILL LEAD TO SURFACE CYCLOGENESIS ACROSS THE OHIO VALLEY ON WEDNESDAY. THE 12Z MODEL SUITE HOWEVER SHOW TREMENDOUS VARIATION IN TIMING AND LOCATION OF EXPECTED SURFACE LOW DEVELOPMENT. IT APPEARS THAT THE MODEL SOLUTIONS HAVE QUITE SERIOUS CONVECTIVE FEEDBACK ISSUES WHICH GREATLY AFFECTS THEIR HANDLING IN SURFACE LOW DEVELOPMENT OVER THE LOWER OHIO VALLEY. THIS LEADS TO CONSIDERABLE FORECAST UNCERTAINTY WITH RESPECT TO TIMING CONVECTIVE EPISODES WED AND WED NIGHT. THE BULK OF MODEL SOLUTIONS DO INDICATE TWO SEPARATE SURFACE LOWS LIFTING ACROSS THE STATE...THE FIRST WED AFTERNOON AND THE SECOND SOMETIME WED NIGHT. STRONG MOISTURE TRANSPORT/MOIST ISENTROPIC ASCENT WILL ACCOMPANY THIS FIRST WAVE INTO THE STATE ON WEDNESDAY...LEADING TO FAIRLY WIDESPREAD SHOWERS. THE CURRENT SPC DAY2 CONVECTIVE OUTLOOK HAS MOST OF SE MI IN A SLIGHT RISK FOR SEVERE WEATHER ON WEDNESDAY. THIS WILL BE DEPENDENT UPON THE TRACK OF THE LOW. THE NAM AND CANADIAN SOLUTIONS...WHICH INDICATE A STRONGER AND MUCH DEEPER LOW TRACKING WEST OF THE FORECAST AREA WOULD BRING SURFACE BASED INSTABILITY INTO SE MI. THE STRONGLY SHEARED ENVIRONMENT COUPLED WITH THE POTENTIAL INSTABILITY WOULD CERTAINLY POSE THE THREAT FOR ORGANIZED STRONG TO SEVERE CONVECTION. THE SECOND WAVE WED NIGHT WOULD ACCOMPANY THE MID LEVEL TROUGH AXIS LIFTING NORTH ACROSS THE REGION. THIS WAVE WOULD LIKELY POSE MORE OF A HEAVY RAIN THREAT AS MOST SOLUTIONS INDICATE A FAIRLY STRONG DEFORMATION AXIS ALONG THE NORTHWEST FLANK OF THIS WAVE. AGAIN...GIVEN THE UNCERTAINTY IN TRACK OF THIS WAVE...WILL NOT BE ISSUING ANY FLOOD WATCHES WITH THIS PACKAGE. UPPER LEVEL PHASING WILL LEAD TO A BROAD UPPER LOW OVER THE REGION BY THURSDAY. WRAP AROUND MOISTURE ALONG WITH STEEP LOW LEVEL LAPSE RATES UNDER COLD AIR ADVECTION WILL PROVIDE A HIGH LIKELIHOOD OF SHOWERS THROUGH THE DAY THURSDAY. THE MEDIUM RANGE SOLUTION DO INDICATE A FAIRLY PROGRESSIVE PATTERN BY LATE IN THE WEEK...WITH HIGH AMPLITUDE RIDGING OVERSPREADING THE REGION BY FRIDAY. THIS WILL PROVIDE A MUCH NEEDED BREAK FROM THE RAINFALL. THERE IS SOME DISAGREEMENT WITH RESPECT TO TIMING AND AMPLITUDE OF ANOTHER LONG WAVE TROUGH FORECAST TO ROTATE INTO THE CENTRAL US OVER THE WEEKEND. THE GFS/CANADIAN/UKMET REMAIN MORE PROGRESSIVE WITH THE NORTHERN STREAM AND THUS JUST BRING SOME FRONTAL PRECIP THROUGH THE AREA SAT NIGHT...WITH DRIER AND COOLER CONDITIONS TOWARD THE END OF THE LONG TERM. GIVEN THE AGREEMENT AMONG THESE SOLUTIONS...HAVE TRENDED THE FORECAST TOWARD THIS DIRECTION. THE ECMWF SOLUTION HOWEVER IS DEEPER AND SLOWER AND INDICATES THE POTENTIAL FOR ANOTHER WET PATTERN LATE IN THE WEEKEND INTO EARLY NEXT WEEK AND WILL BE SOMETHING TO WATCH OVER THE NEXT FEW MODEL RUNS. && .MARINE... WINDS WILL INCREASE OUT OF THE SOUTH AHEAD OF THE NEXT LOW PRESSURE SYSTEM...WHICH WILL LIFT OUT OF THE OHIO RIVER VALLEY ON WEDNESDAY. UNCERTAINTY CURRENTLY EXISTS WITH REGARDS TO THE EXACT TRACK AND STRENGTH OF THE LOW...AND CHANGES IN THE FORECAST TRACK WOULD HAVE AN EFFECT ON THE RESULTANT WINDS. AT THIS TIME...STRENGTHENING SOUTHERLY WINDS ARE EXPECTED TO DEVELOP TOMORROW AFTERNOON BEFORE VEERING TO THE SOUTHWEST LATE WED NIGHT AND INTO THURSDAY MORNING. ATTM...WINDS ARE NOT EXPECTED TO MEET ADVISORY CRITERIA. SHOWERS AND THUNDERSTORMS WILL ALSO BE A DISRUPTION TO MARINE INTERESTS PERIODICALLY TODAY THROUGH THURSDAY. && .AVIATION...ISSUED 200 PM EDT TUE APR 26 2011 A STRONG LOW PRESSURE SYSTEM LOCATED OVER NORTHERN ILLINOIS WILL LIFT NORTHEAST TOWARDS LAKE MICHIGAN THIS AFTERNOON. A WARM FRONT HAS SURGED NORTH ACROSS SOUTHEAST MICHIGAN WITH BREEZY SOUTHERLY WINDS DEVELOPING BEHIND THE FRONT...AND WINDS OCCASIONALLY GUSTING TO BETWEEN 25-30 KNOTS. AN AREA OF MVFR CEILINGS AROUND 2500 FEET HAS DEVELOPED ACROSS SOUTHWEST LOWER MICHIGAN INTO NORTHERN INDIANA AND WILL CONTINUE TO SLOWLY ADVANCE NORTH NORTHEAST THIS AFTERNOON. SCATTERED LIGHT SHOWERS DEVELOPING IN THIS AREA MAY START TO SPREAD NORTHEAST INTO MBS/FNT AFTER 20Z...GRADUALLY EXTENDING SOUTH TOWARDS DET/DTW TOWARDS 22Z. WE CONTINUE TO MONITOR THUNDERSTORMS DEVELOPMENT ACROSS EASTERN ILLINOIS AND INDIANA WHERE INSTABILITY IS INCREASING. SCATTERED SHOWERS AND THUNDERSTORMS DEVELOPING IN THIS AREA WILL MOVE NORTHEAST TOWARDS THE AREA THROUGH LATE AFTERNOON. SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE BETWEEN 22-03Z AND HAVE ADDED A BRIEF TEMPO AT FNT/PTK/DTW/DET WHERE THUNDERSTORMS ARE MOST LIKELY. THUNDERSTORMS TODAY DO HAVE THE POTENTIAL TO BE STRONG AND A FEW WIND GUSTS IN EXCESS OF 40 KNOTS ARE POSSIBLE. POOR AVIATION CONDITIONS ARE EXPECTED IN THE WAKE OF THESE SHOWERS. STRATUS IS EXPECTED TO FILL IN AFTER 04Z AND WITH CEILINGS BELOW 1000 FEET LIKELY. ANOTHER WAVE OF LOW PRESSURE IS EXPECTED TO TRACK UP THE MISSISSIPPI VALLEY TOWARDS LOWER MICHIGAN TOWARDS DAWN BRINGING ANOTHER SURGE OF MOISTURE WITH WIDESPREAD RAIN AFTER 13Z. && .DTX WATCHES/WARNINGS/ADVISORIES...
