AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 125 PM EDT FRI JUN 30 2006 .AVIATION... HIGH PRESSURE CENTERED OVER THE OHIO RIVER VALLEY WILL KEEP GOOD AVIATION CONDITIONS OVER THE AREA THROUGH TOMORROW MORNING. SOME SCATTERED CU WILL DEVELOP FOR THE AFTERNOON HOURS THEN CLEAR OUT BY TONIGHT. ON SATURDAY...BREEZY SOUTHWESTERLY WINDS WILL DEVELOP BY LATE MORNING AHEAD OF A SURFACE TROUGH MOVING THROUGH THE REGION. THERE IS A CHANCE OF SHOWERS AND ISOLATED THUNDERSTORMS BY EARLY AFTERNOON AT THE NORTHERN TAF SITES WITH A BETTER CHANCE FOR THUNDERSTORMS AT ALL TAF SITES BY LATE AFTERNOON. SOME THUNDERSTORMS ON SATURDAY AFTERNOON AND EVENING MAY BE CAPABLE OF PRODUCING STRONG WIND GUSTS AND HEAVY RAIN. THE COVERAGE OF THUNDERSTORMS IS EXPECTED TO BE GREATER ACROSS THE NORTHERN TAF SITES THROUGH THE AFTERNOON AND EVENING HOURS. && .UPDATE...ISSUED 1100 AM EDT FRI JUN 30 2006 ALTO CU DECK OVER THE THUMB WILL CONTINUE TO BREAK UP AS IT MOVES OFF TO THE EAST THROUGH EARLY AFTERNOON. A FEW LIGHT SPRINKLES OR SHOWERS HAVE MOVED ACROSS THE CWA THIS MORNING BUT WILL CONTINUE TO DISSIPATE THROUGH THE REMAINDER OF THE MORNING. KAPX 12Z SOUNDING ALREADY SHOWED A CAP IN PLACE AROUND 650MB AS DRIER AIR IN THE MID LEVELS ADVECTS SOUTH. HAVE SENT OUT AN UPDATE TO THE FORECAST TO REMOVE THE ISOLATED THUNDERSTORM MENTION THIS MORNING AND TO CHANGE ANY REMAINING SHOWERS TO LIGHT. ALTHOUGH TEMPS HAVE GOTTEN A SLOW START OVER THE THUMB...HAVE ONLY LOWERED EXPECTED HIGHS A DEGREE OR TWO. AS CLOUDS CLEAR...TEMPS HAVE RISEN AS MUCH AS FIVE DEGREES IN ONE HOUR SO STILL ANTICIPATE HIGHS TO END UP CLOSE TO PREVIOUS FORECAST. && .PREV DISCUSSION...ISSUED 409 AM EDT FRI JUN 30 2006 SHORT TERM...TODAY AND TONIGHT SATELLITE IMAGERY AND MODEL ANALYSIS FIELDS SHOWED A STRONG JET SEGMENT DRIVING A WAVE IN THE NORTHERN GREAT LAKES EARLY THIS MORNING. UPPER AIR OBS AT 00Z OVER NORTHERN ONTARIO WERE IN THE 80 TO 90 KNOT RANGE AT 250 MB. THIS WAVE CAUSED FLOW TO BACK IN THE LOW AND MID LEVELS AND START SOME THETA-E ADVECTION OVER NORTHERN LOWER AND THIS HAS LED TO SCATTERED SHOWERS AND ISOLATED STORMS MOVING FROM THERE INTO THE TRI CITIES AND THUMB. WE WILL CARRY THIS IN THE FORECAST AT LEAST THROUGH THE MORNING HOURS. WESTERLY LOW LEVEL FLOW TRAILING THIS SYSTEM WILL ALSO HELP WARM THINGS UP A BIT FROM YESTERDAY. HIGHS IN THE LOWER 80S LOOK ON TARGET, ESPECIALLY IN THE SOUTH WHERE THERE WILL BE NO DELAY IN DAYTIME HEATING. THE WAVE WILL BE TO OUR EAST THIS AFTERNOON WITH MID LEVEL SUBSIDENCE SETTLING OVER LOWER MICHIGAN. THIS WILL BE ENOUGH TO SUPPRESS CONVECTION IN LIGHT OF WARMING MID LEVEL TEMPERATURES AND A SLOW START TO SURFACE HEATING THIS AFTERNOON ONCE THE MORNING ACTIVITY DEPARTS TO OUR EAST. THE 00Z NAM LOOKS TOO AGGRESSIVE ON AFTERNOON CONVECTION NEAR THE LAKE HURON SHORELINE CONSIDERING THE CHANGING LARGER SCALE ENVIRONMENT. DRY CONDITIONS WILL THEN PERSIST TONIGHT AS WEAK HIGH PRESSURE WILL BE IN PLACE OVER SE MICHIGAN. EVEN THE MOST AGGRESSIVE 00Z GFS KEEPS SHOWERS AND STORMS TO OUR WEST OVERNIGHT, BUT IT WILL BE CLOSE. THE FORCING FOR SHOWERS AND STORMS WILL BE ASSOCIATED WITH THE NEXT LOW PRESSURE SYSTEM NOW GETTING ORGANIZED OVER CENTRAL CANADA AND THE NORTHERN PLAINS. NOCTURNAL CONVECTION WILL BE DRIVEN BY LOW LEVEL JET FORCED WARM ADVECTION WHICH WILL BE ON OUR DOORSTEP BY 12Z BUT NOT AS STRONG AS FARTHER WEST. WE WILL AT LEAST SEE AN INCREASE IN HIGH CLOUDS AFTER MIDNIGHT. LONG TERM...SATURDAY THROUGH THURSDAY AMPLIFIED PATTERN WITH THE WESTERN RIDGE AND EASTERN TROUGH WILL FLATTEN SOMEWHAT THROUGH THE WEEKEND...BUT WITH THE GREAT LAKES REMAINING UNDER WEAKLY CYCLONIC UPPER FLOW. SHORTWAVE CURRENTLY CRESTING THE WESTERN RIDGE WILL TRACK INTO MICHIGAN ON SATURDAY... HELPING TO PROPEL A SURFACE WAVE THROUGH THE REGION. NAM/GFS STILL HAVE THEIR DIFFERENCES...BUT HAVE COME INTO SOMEWHAT BETTER AGREEMENT. NAM HAS TRENDED MORE TOWARD THE GFS...WITH BOTH LIFTING A WARM FRONT THROUGH LOWER MICHIGAN ON SATURDAY. CONVECTIVE FEEDBACK IS STILL A PROBLEM...EARLIER IN THE GFS AND LATER IN THE NAM. HOWEVER THE OVERALL PATTERN LOOKS REASONABLE...WITH THE PREFERENCE TOWARD THE SOMEWHAT MORE PROGRESSIVE GFS SOLUTION AS THE SURFACE LOW CONTINUES DOWNSTREAM. GOOD SHOT FOR CONVECTION ON SATURDAY WITH POTENTIAL FOR SEVERE WEATHER. SHORTWAVE WILL TRACK NORTH OF THE CWA...BUT GOOD LIFT/CONVERGENCE EXPECTED ALONG THE WARM FRONT AS IT LIFTS INTO LOWER MICHIGAN. THERE SHOULD BE DECENT INSTABILITY AVAILABLE...WITH OVER 1500J/KG CAPE FROM MODIFIED GFS FORECAST SOUNDINGS. UPPER JET IS ACTUALLY RATHER WEAK BUT WITH THE HINT OF A LEFT-EXIT REGION...OTHERWISE LOW-MID LEVEL WINDS ARE RATHER STRONG AND UNIDIRECTIONAL /WEST AT 40-50KTS/. GOOD LOW-LEVEL TURNING IN THE HODOGRAPH THOUGH WITH SOUTHERLY SURFACE WINDS...LEADING TO 0-3KM HELICITY OVER 500M2/S2 BY 00Z. THE SETUP LOOKS FAVORABLE FOR A BOW ECHO CONVECTIVE MODE...WITH WIND DAMAGE AS THE PRIMARY THREAT. AFTERNOON/EVENING TIMING CENTERED AROUND 20-00Z LOOKS MOST FAVORABLE...AND WILL BUMP POPS UP A BIT AND KEEP THE SCATTERED WORDING. AS FAR AS TEMPERATURES...NAM HAS BACKED OFF TOWARD THE GFS MOS AS IT IS NOW SLOWER LIFTING THE WARM FRONT THROUGH THE CWA. ACTUALLY AM CONCERNED ABOUT CLOUDS/PRECIP DEVELOPING EARLIER IN THE DAY ALONG THE FRONT...LIMITING INSOLATION ACROSS THE CWA AND KEEPING TEMPERATURES ON THE COOL SIDE. COLD FRONT SWINGS THROUGH OVERNIGHT...BUT WILL LITTLE LIFT/CONVERGENCE ALONG IT. WILL HOLD ONTO A LOW CHANCE POP ALONG IT...BUT OTHERWISE DECREASING CLOUDS AS DEEP MOISTURE STRIPS AWAY. THE BOUNDARY WILL STALL JUST SOUTH OF THE CWA...WITH LITTLE DEFINITION AND NO UPPER SUPPORT. HOWEVER GIVEN ITS PRESENCE WITH DECENT INSTABILITY WILL KEEP A CHANCE GOING ACROSS THE SOUTHERN CWA. NEXT SYSTEM SWINGS IN FROM THE NORTHWEST SUNDAY NIGHT/MONDAY. GFS HAS TRENDED SLOWER...AND IS SUPPORTED BY BY NAM/WRF-HEMI IN BRINGING A BETTER DEFINED COLD FRONT THROUGH LOWER MICHIGAN ON MONDAY. BUMPED POPS UP TO 40 PERCENT FOR MONDAY GIVEN THE CONVERGENCE ON THE CURRENT SOLUTION. THE LONGWAVE PATTERN WILL TRANSITION BACK TO A SOMEWHAT MORE AMPLIFIED NORTHWESTERLY FLOW ACROSS THE GREAT LAKES AS THE WESTERN RIDGE REASSERTS ITSELF AHEAD OF ADDITIONAL ENERGY DIGGING OUT OVER THE PACIFIC. SURFACE HIGH PRESSURE WILL DOMINATE ACROSS THE REGION THROUGH THE REMAINDER OF THE EXTENDED PERIOD. TEMPERATURES WILL START OUT NEAR TO SLIGHTLY BELOW NORMAL FOR THE FIRST PART OF THE WEEK...THEN SLOWLY WARM JUST ABOVE NORMAL BY THE END OF THE FORECAST PERIOD AS WE DEVELOP MORE OF A SOUTHWESTERLY FLOW BEHIND THE SURFACE HIGH. && .DTX WATCHES/WARNINGS/ADVISORIES...
