Area forecast discussion, Jun 13, 3:43 PM EDT, 1 hour 58 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 343 PM EDT SUN JUN 13 2004 .DISCUSSION... ON THE HEELS OF THE SUPERCELL IN CENTRAL LOWER MICHIGAN, THERE IS STILL PLENTY OF INSTABILITY IN THE LEE OF LAKE MICHIGAN DOWN INTO NORTHERN INDIANA AND EAST THROUGH ALL OF SOUTHEAST MICHIGAN. THIS MOIST AND UNSTABLE AIR MASS IS AWAITING CONTINUED UPPER SUPPORT FROM A SHORT WAVE OVER ILLINOIS. SURFACE CONVERGENCE, ENHANCED BY THE LAKE BREEZE AND PREFRONTAL TROF OVER SW LOWER, WILL HELP FOCUS CONTINUED STORM DEVELOPMENT FROM NORTHERN INDIANA AND NEW STORM DEVELOPMENT OVER SW LOWER TOWARD PEAK HEATING AND INTO THE EARLY EVENING. SEVERE WEATHER POTENTIAL REMAINS HIGH WITH MOST UNSTABLE CAPE NEAR 3 KJ/KG AND 0-6KM SHEAR AROUND 30 M/S. THIS HAS BEEN AND WILL CONTINUE TO BE SUFFICIENT FOR SPLITTING SUPERCELLS CAPABLE OF TORNADOES. IN ADDITION, MATURE CONVECTION WILL BE CAPABLE OF DEVELOPING INTO BOWS WITH DAMAGING WIND GUSTS, TO GO ALONG WITH LARGE HAIL AND HEAVY RAINFALL. THE ENTIRE SYSTEM WILL BE TO OUR EAST BY LATE EVENING WITH DRY CONDITIONS EXPECTED DURING THE OVERNIGHT HOURS. ALL OF THE SHORT RANGE MODELS DEPICT A SHARP THETA-E TROF THAT WILL SPREAD OVER LOWER MICHIGAN OVERNIGHT, ON THE HEELS OF THE SHORT WAVE AND SURFACE TROF. THIS WILL OCCUR IN THE 850 TO 700 MB LAYER AND IS A SIMILAR MOISTURE PROFILE TO LAST NIGHT WHICH PREVENTED NOCTURNAL CONVECTIVE DEVELOPMENT. IT LOOKS LIKE THE LOW LEVEL JET AND BEST MOISTURE RETURN WILL SET UP OVER IOWA OVERNIGHT. SOME SORT OF MCS IS LIKELY TO DEVELOP IN THAT AREA AND MOVE EAST WITH THE MOIST AXIS DURING MONDAY MORNING. MOISTURE ADVECTION, SHORT WAVE SUPPORT, AND A STRONG UPPER JET WILL HELP SUSTAIN THE SYSTEM LONG ENOUGH FOR IT TO REACH SE MICHIGAN IN A MATURE STAGE DURING THE 12Z TO 18Z TIMEFRAME, THEN LAST INTO THE AFTERNOON. LINGERING BOUNDARY LAYER INSTABILITY, AROUND 2000 J/KG OVER SE MICHIGAN DURING THE MORNING, WILL MAKE SEVERE WEATHER A POSSIBILITY. SEVERE POTENTIAL DURING THE AFTERNOON WILL BE STRONGLY INFLUENCED BY THE EVOLUTION OF THE REMAINS OF THE NOCTURNAL ACTIVITY AND ANY OUTFLOW/MESOSCALE BOUNDARIES. INSTABILITY AND SHEAR WILL BE PLENTY ADEQUATE FOR ORGANIZED STORMS DURING THE AFTERNOON. HIGH PRESSURE WILL BUILD INTO THE AREA MONDAY NIGHT AND TUESDAY AND GIVE US A BREAK IN THE ACTION UNTIL THE NEXT SYSTEM ARRIVES ON WEDNESDAY. THE LONG RANGE MODELS REMAIN IN GOOD AGREEMENT ON DEVELOPMENTS FOR THE LARGE SCALE UPPER PATTERN. ALL SHOW THE WEDNESDAY FRONTAL SYSTEM THROUGH THE GREAT LAKES BY THURSDAY MORNING WITH HIGH PRESSURE IN PLACE OVER SE MICHIGAN. THE LARGE UPPER TROF OVER CENTRAL CANADA WILL THEN DIG AGGRESSIVELY INTO THE MIDWEST ON FRIDAY AND BRING IN A ROUND OF BELOW NORMAL TEMPERATURES BY SATURDAY WITH ANOTHER ROUND OF SHOWERS AND STORMS WITH THE ASSOCIATED SHORT WAVE AND COLD FRONT. PLAN TO START SUNDAY OFF ON THE COOL AND DRY SIDE AS CANADIAN HIGH PRESSURE SETTLES OVER THE REGION. && .DTX WATCHES/WARNINGS/ADVISORIES...NONE. && BT EXPERIMENTAL GRAPHICAL FORECASTS ARE AVAILABLE ONLINE AT HTTP://WWW.CRH.NOAA.GOV/DTX (ALL LOWER CASE)
