AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 930 AM EDT FRI JUN 11 2004 .UPDATE... FAIRLY DEEP (4000 FEET) LOW LEVEL EASTERLY FLOW CONTINUES TO ADVECT DRIER AIR INTO SOUTHEAST MICHIGAN FROM EASTERN ONTARIO. SURFACE DEW POINTS HAVE DROPPED INTO THE UPPER 40S TO MID 50S. 24 HOUR RAINFALL TOTALS RANGED FROM A HALF AN INCH ACROSS THE ANN ARBOR/DETROIT AREA WITH UP TO 2.25 INCHES TOWARD THE OHIO BORDER. SOME SPECIFIC AMOUNTS THROUGH 8 AM. DET 0.42 INCHES BOLLES HARBOR 0.50 INCHES DTW 0.51 INCHES ARB 0.60 INCHES HELL 0.75 INCHES MONROE 1.02 INCHES MILFORD 1.05 INCHES HUDSON (3E) 1.49 INCHES TECUMSEH 2.15 INCHES CURRENT RADAR TRENDS CONTINUE TO SUPPORT HEAVIEST RAINFALL REMAINING SOUTH OF LOWER MICHIGAN...AS 925 TO 850 MB FGEN REMAINS JUST SOUTH OF THE BORDER. SURFACE BASED INSTABILITY/THUNDERSTORMS TO REMAIN COMFORTABLY SOUTH OF THE CWA ACROSS CENTRAL INDIANA/OHIO. ZONES IN GOOD SHAPE...AS PRECIPITATION WILL TAPER OFF THIS AFTERNOON...WITH AMPLIFYING UPPER LEVEL RIDGE MOVING OVER THE CENTRAL GREAT LAKES REGION. WILL MAKE A FEW PHONE CALLS ACROSS THE SOUTHERN THIRD OF THE CWA...TO MAKE SURE FLOODING IS NOT AN ISSUE BEFORE DROPPING THE FLOOD WATCH. ALTHOUGH...MAY NEED TO ISSUE ANOTHER FLOOD WARNING FOR THE HURON RIVER AT HAMBURG AS IT IS RIGHT AT FLOOD STAGE. NO ZONE UPDATE PLANNED AT THE MOMENT. SF .PREVIOUS DISCUSSION ISSUED AT 407 AM... A DEEP UPPER LOW IS SITUATED OFF THE EAST COAST OF CANADA...WITH AN UPPER LEVEL JET AXIS EXTENDING FROM NORTHERN ONTARIO THROUGH SOUTHERN QUEBEC PER 12Z UPPER AIR PLOTS AND CURRENT WATER VAPOR LOOP. ANOTHER UPPER LOW IS ROTATING OVER NORTHERN WYOMING...WHILE A SHARP UPPER LEVEL RIDGE AXIS EXTENDS ACROSS THE UPPER MISSISSIPPI VALLEY/WESTERN GREAT LAKES REGION. MEANWHILE...AT THE SURFACE HIGH PRESSURE IS LOCATED OVER JAMES BAY...WITH A NEARLY STATIONARY FRONTAL BOUNDARY LOCATED FROM JUST NORTH OF CHICAGO TO NEAR DAYTON OHIO. THE WATER VAPOR IMAGERY SHOWS A NICE PLUME OF SUB TROPICAL MOISTURE EXTENDING FROM THE TEXAS GULF COAST INTO THE OHIO VALLEY/SOUTHERN GREAT LAKES. THE 12Z UPPER AIR PLOTS SHOWED PRECIPITABLE WATER VALUES IN THIS REGION BETWEEN 1.75 AND 2.0 INCHES AND 700MB DEWPOINTS OF 3 TO 5 DEG C. HEAVY RAINFALL TODAY WILL BE THE MAIN FORECAST CONCERNS WITH THIS PACKAGE. AREA RADARS SHOWS A SWATH OF RAIN FROM CENTRAL WISCONSIN TO CENTRAL INDIANA. STRONG CONVECTION THAT MOVED ACROSS NORTHERN INDIANA A FEW HOURS AGO HAS NOTICEABLY DISRUPTED THE INFLOW ALONG THE SURFACE BOUNDARY. BASED ON PROFILER DATA AND THE IR SATELLITE LOOP...IT APPEARS THAT THE STRONGEST LOW LEVEL CONVERGENCE HAS SHIFTED INTO CENTRAL ILLINOIS/INDIANA...A LITTLE FARTHER SOUTH THAN THE 00Z MODEL SUITE INDICATED. DEEP LAYER FRONTOGENETICAL LIFT AS WELL AS LIFT AHEAD OF A PAIR OF SHORT WAVE TROUGHS RIDING ATOP THE RIDGE AXIS IS STILL GENERATING PLENTY OF RAINFALL ACROSS THE SOTHERN GREAT LAKES. THE SHORT WAVES WILL MOVE SOUTHEAST INTO SOUTHERN LOWER MI THIS MORNING AS THE RIDGE AMPLIFIES OVER THE WESTERN GREAT LAKES. THIS WILL INCREASE THE CONFLUENT FLOW ALOFT OVER THE REGION AND STRENGTHEN THE FRONTOGENETICAL LIFT WITHIN THE ENTRANCE REGION OF THE UPPER LEVEL JET OVER CANADA. A VERY STRONG MOISTURE GRADIENT WILL EXIST OVER SE MICHIGAN TODAY...THE 00Z KAPX SOUNDING ACTUALLY HAD A 30 DEG DEWPOINT DEPRESSION AT 850MB. THIS DRY AIR WILL BUILD ACROSS THE SAGINAW VALLEY AND THUMB REGION TODAY. WITH THE DEEPEST MOISTURE AND LIFT FOCUSSED SOUTH...WILL CONTINUE WITH CATEGORICAL POPS SOUTH...DECREASING POPS TO THE NORTH. WILL ACTUALLY CARRY A DRY FORECAST IN THE THUMB REGION DUE TO THE DRY AIR ADVECTING IN FROM THE NORTHEAST. AS FAR AS THE FLOOD WATCH GOES...THE STRONGER CONVECTION LOOKS TO BE SETTING UP MUCH FARTHER SOUTH. THUS FAR...QPF HAS BEEN LESS THAN 0.15 INCHES SOUTH OF I-94. GIVEN THE AMOUNT OF FRONTOGENETICAL LIFT EXPECTED ACROSS THE FAR SOUTHERN PORTIONS OF THE FORECAST AREA TODAY...WILL STILL MAINTAIN THE FLOOD WATCH ALONG AND SOUTH OF A DETROIT TO ANN ARBOR LINE AND DROP IT TO THE NORTH. THE ETA SOLUTION SHOWS THE BULK OF THE PRECIPITATION FALLING ALONG AND SOUTH OF A LINE FROM LAN TO TOL. HOWEVER...PRECIP UPSTREAM IS FALLING MUCH FARTHER NORTH THAN THE ETA INDICATES...SO WILL ACCOUNT FOR THIS IN THE GRIDS. ELEVATED INSTABILITY WILL BE QUITE WEAK PER MODEL SOUNDINGS. ETA CROSS SECTIONS DO SHOW SOME POTENTIAL INSTABILITY ABOVE 925MB...SO WILL MAINTAIN A MENTION OF THUNDER. ANY STORM WILL BE CAPABLE OF TORRENTIAL RAINFALL TODAY BASED ON THE AMOUNT OF AVAILABLE MOISTURE AND HIGH FREEZING LEVELS. WARM CLOUD PROCESSES WILL BE VERY EFFICIENT AT PRODUCING HEAVY RAINFALL. SO THERE IS STILL A POTENTIAL FOR RAINFALL AMOUNTS TO EXCEED TWO INCHES IN THE WATCH AREA TODAY. WILL CONTINUE A LOW CHANCE FOR LIGHT RAIN ACROSS THE SOUTH THIS EVENING TO ACCOUNT FOR SOME LINGERING FRONTOGENETICAL LIFT. OTHERWISE...THE SURFACE HIGH WILL BUILD INTO THE EASTERN GREAT LAKES...ADVECTING MUCH DRYER AIR ACROSS SE MICHIGAN. THE 00Z MODEL SUITE ARE IN VERY GOOD AGREEMENT THROUGH THE WEEKEND SHOWING THE UPPER LOW OUT WEST LIFTING INTO CANADA THEN GRADUALLY WEAKENING...BREAKING DOWN THE UPPER RIDGE THAT WILL BE OVER THE EASTERN LAKES REGION ON SATURDAY. THE UPPER FLOW WILL THEN BECOME A LITTLE MORE ZONAL TOWARD THE END OF THE WEEKEND...WITH THE SURFACE FEATURES FAIRLY DIFFUSE. ON SATURDAY...STRONG 850MB MOISTURE ADVECTION WILL WORK EAST ACROSS THE FORECAST AREA VERY SLOWLY...WITH THE BEST INSTABILITY LOCATED OVER SW LOWER MICHIGAN. WILL CONTINUE WITH CHANCE POPS ACROSS THE WESTERN HALF OF THE FORECAST AREA TO ACCOUNT FOR CONVECTION MOVING IN FROM WESTERN LOWER. EXPECT ANY CONVECTION WILL STRUGGLE TO MOVE EAST INTO THE MORE STABLE AIR OVER SE MICHIGAN. CHANCE OF POPS LOOK GOOD ON SUNDAY INTO MONDAY AS A MOIST/UNSTABLE AIRMASS WILL RESIDE OVER THE REGION. THE LATEST GFS...CANADIAN AND TO A LESSOR EXTENT THE ETAXX ARE BACKING OFF ON TIMING AND STRENGTH OF HIGH PRESSURE BUILDING INTO THE REGION MID WEEK. THEY ARE ALSO SLOWER TO MOVE A COLD FRONT THROUGH THE AREA. WILL THEREFORE ADD A CHANCE OF THUNDERSTORMS TO TUESDAY. OTHERWISE...NO ADDITIONAL UPDATES WILL BE MADE TO THE FORECAST BEYOND SUNDAY. && .DTX WATCHES/WARNINGS/ADVISORIES...FLOOD WATCH...TODAY...
