SOUTHEAST MICHIGAN AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 453 AM EDT SUN JUL 28 2002 CURRENTLY CHASING THE CONVECTION ALONG THE SURGE OF DEEP HIGH THETA-E AIR OUT OF THE FORECAST AREA. ADDITIONAL ACTIVITY ACROSS CENTRAL LOWER CONTINUES ITS TREK NORTHEAST. WILL CARRY NUMEROUS WORDING ACROSS THE NORTH TO COVER CURRENT ACTIVITY. OTHERWISE... SKIES ARE CLEARING ACROSS THE SOUTH SO WILL HAVE MOSTLY SUNNY CONDITIONS FOR THE MORNING, BEFORE THE CU FIELD DEVELOPS WITH THE HEATING OF THE DAY. SPEAKING OF THE HEAT OF THE DAY, WITH HIGHS EXPECTED TO BE AROUND 90, IF NOT A COUPLE DEGREES HIGHER, AND DEWPOINTS IN THE 70-75F RANGE- HEAT INDICES WILL CLIMB TO AROUND 100. WILL HOLD ON A HEAT ADVISORY FOR NOW, BUT IF THE AREA SEES A LONGER PERIOD OF SUN THAN CURRENTLY EXPECTED, ADVISORY CRITERIA IS NOT OUT OF THE QUESTION. SYNOPTIC-SCALE BOUNDARY IS PROGGED TO HANG AROUND SOUTHERN LOWER MICHIGAN THROUGH THE DAY AS ANOTHER SURGE OF HIGH THETA-E AIR AT 850 AND 700MB MOVES IN FROM THE SOUTHWEST IN ADVANCE OF A WEAK SHORTWAVE. THE SOUTHERN THIRD OF THE LOWER PENINSULA WILL BE UNDER THE INFLUENCE OF THE DIRECT THERMAL CIRCULATION SUPPORTED BY THE RIGHT ENTRANCE REGION TO A 300MB SPEED MAX TRAVERSING THE CENTRAL LAKES REGION THIS AFTERNOON. THIS IN COMBINATION WITH THE QUASI-STATIONARY SYNOPTIC-SCALE BOUNDARY AND PRE-EXISTING OUTFLOW BOUNDARIES FROM THIS MORNING/S CONVECTION SHOULD BE ENOUGH TO AID ADDITIONAL CONVECTIVE INITIATION WITH THE HEAT OF THE DAY. ETA HOURLY SOUNDINGS INDICATE THAT CAPES WILL CLIMB INTO THE 2500 J/KG RANGE ACROSS THE CWFA WITH THE MOIST LAYER EXTENDING TO 700MB AND SUBSTANTIAL DRYING ABOVE THAT. TEMPS AT 700MB SHOULD STAY BELOW +10C KEEPING THE REGION NORTH OF THE EDGE OF THE CAPPING INVERSION THAT SETUP ACROSS THE MID-MISSISSIPPI VALLEY YESTERDAY. THE DRY AIR ALOFT IN COMBINATION WITH THE INCREASING MOMENTUM IN THE PROFILE COULD SUPPORT A FEW SEVERE CELLS ONCE AGAIN TODAY, WITH WIND BEING THE PRIMARY THREAT, AS THE FREEZING LEVEL WILL STILL BE AROUND 15KFT. THE HODOGRAPH IS REASONABLY STRAIGHT WITH MODEST SHEAR IN THE LOWEST 2KM, LENDING TO SOME ORGANIZATION BUT MORE OF THE SHORT LINEAR VARIETY. WILL ALSO HAVE TO KEEP A WATCHFUL EYE UPSTREAM AS ADDITIONAL ORGANIZED CONVECTION IS EXPECTED ACROSS IOWA AND MINNESOTA DURING THE EVENING, WHICH MAY MOVE INTO THE SOUTHERN LAKES REGION OVERNIGHT. INSTABILITY ACROSS THE REGION WOULD CERTAIN SUPPORT CONTINUED NOCTURNAL DEVELOPMENT. SO, WITH CONTINUE THE CHANCE FOR SHOWERS AND STORMS TONIGHT. THE BEST CHANCE WILL STILL COME MONDAY, WHEN THE STRONGER SHORTWAVE OVER THE ROCKIES ARRIVES, WITH THE ASSOCIATED SURFACE COOL FRONT. THE SURFACE BOUNDARY SHOULD PROVIDE AMPLE BOUNDARY LAYER CONVERGENCE AND SHEAR TO SUPPORT ORGANIZED CONVECTION ALONG AND AHEAD OF IT MONDAY AFTERNOON, MOST LIKELY A SQUALL LINE. THE THERMODYNAMICS WILL ALSO BE FAVORABLE FOR STRONG UPDRAFTS, WITH CAPES PROGGED TO AROUND 2500 J/KG AGAIN. THUS, WILL CONTINUE TO ADVERTISE LIKELY POPS. NO CHANGES TO THE EXTENDED. .DTX...NONE.
