NWS Detroit, MI wrote its last area forecast discussion before the first event at Jul 23, 10:17 AM EST, 23 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 1117 AM EDT SUN JUL 23 2006 .UPDATE... SHORTWAVE APPARENT IN WATER VAPOR LOOP NEAR THE STRAITS WILL DROP SOUTHEASTWARD ACROSS LAKE HURON THIS AFTERNOON. THE SURFACE FRONT FROM YESTERDAY HAS ALL BUT WASHED OUT...HOWEVER THERE REMAINS A WEAK TROUGH FROM SOUTHEAST ONTARIO AND LOWER MICHIGAN. 12Z RUC LOOKS UNDERDONE IN ITS DEPICTION OF A WEAK THETA-E RIDGE ACROSS NORTHERN LOWER/LAKE HURON...WHERE CLOUDS HAVE MAINTAINED AND A FEW SHOWERS HAVE BEEN PERCOLATING THIS MORNING. WITH WEAK CONVERGENCE/MOISTURE AT THE SURFACE AND THE UPPER SUPPORT AHEAD OF THE SHORTWAVE...WE SHOULD SEE CONVECTION INCREASE IN COVERAGE AND INTENSITY AS WE DESTABILIZE THIS AFTERNOON. KEPT SCATTERED WORDING ACROSS THE SAGINAW VALLEY AND THUMB AND INCREASED THE POPS A BIT GIVEN ACTIVITY ALREADY UPSTREAM THIS MORNING. WITH THE SHORTWAVE JUST BRUSHING THE NORTHEASTERN CWA...KEPT ISOLATED COVERAGE ACROSS THE SOUTHWEST THIS AFTERNOON. 12Z APX/TAMDAR SOUNDINGS DO SHOW A STRONGER MID-LEVEL CAP FARTHER NORTH...BUT THIS SHOULD WEAKEN/ERODE WITH THE APPROACH OF THE SHORTWAVE. SOUNDINGS ACROSS SOUTHEAST MICHIGAN SHOW A FAIR AMOUNT OF DRY AIR JUST OFF THE SURFACE. DEWPOINTS CLIMBED BACK NEAR 60F AFTER SUNRISE...BUT AS OF 15Z MANY STATIONS HAVE ALREADY MIXED BACK DOWN INTO THE MID/UPPER 50S. WITHOUT ANY REAL MOISTURE ADVECTION...EXPECT THAT INSTABILITY WILL BE LIMITED GIVEN THE AMOUNT OF DRY LOW-LEVEL AIR. MODIFIED 12Z DTX SOUNDING FOR 80/55 YIELDS 1700J/KG CAPE...WHICH IS LIKELY THE HIGH END AS DEWPOINTS WILL MORE LIKELY MIX DOWN INTO AT LEAST THE LOW 50S. && .PREV DISCUSSION...ISSUED 705 AM EDT SUN JUL 23 2006 AVIATION... WITH THE ONSET OF DAYTIME HEATING AND GIVEN THE COLD AIR ALOFT ASSOCIATED WITH THE UPPER LEVEL TROUGH OVER THE REGION...EXPECT A SCATTERED TO BROKEN CU FIELD TO DEVELOP BY AFTERNOON. CEILING HEIGHTS WILL BE VFR. HOWEVER...A BRIEF PERIOD OF MVFR CEILINGS WILL BE POSSIBLE THIS MORNING AROUND MBS GIVEN THE SLIGHTLY HIGHER BOUNDARY LAYER MOISTURE FROM THE SAGINAW VALLEY NORTHWARD. A SHORT WAVE TROUGH PASSING ACROSS LAKE HURON THIS MORNING AND EARLY AFTERNOON ALONG WITH INCREASING INSTABILITY THROUGHOUT THE DAY SHOULD TOUCH OFF ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON. FEEL THE LIKELIHOOD OF PRECIP HITTING THE TAF SITES REMAINS TOO LOW TO PLACE IN THE TAF AT THIS TIME. SHORT TERM...TODAY AND TONIGHT THE HIGHLY AMPLIFIED PATTERN ACROSS NORTH AMERICA IS FORECAST TO TRANSITION TO A MORE ZONAL PATTERN DURING THE SHORT TERM AS THE STRONG RIDGE OVER THE WESTERN US FLATTENS AND THE LONG WAVE TROUGH OVER THE GREAT LAKES MOVES TO THE NORTHEAST. THE CURRENT WATER VAPOR LOOP SHOWS A RATHER STRONG SHORT WAVE EMBEDDED WITHIN THE MEAN TROUGH ROTATING INTO EASTERN UPPER MI. THIS WAVE IS FORECAST TO MOVE ACROSS SOUTHERN LAKE HURON EARLY THIS AFTERNOON...SPREADING SOME WEAK MID LEVEL LIFT ACROSS SOUTHEAST MI. WOULD EXPECT THAT THIS LIFT WILL ENHANCE SURFACE TROUGHING ACROSS SOUTHERN MICHIGAN...AS INDICATED BY MODEL SOLUTIONS. NAM MODEL SOUNDINGS SHOW SURFACE BASED CAPE OF 1000 TO 1500 J/KG ACROSS THE SAGINAW VALLEY AND THUMB BY AFTERNOON...WITH CAPE DECREASING TO 500 TO 800 J/KG AROUND DETROIT WHERE THERE IS LESS AVAILABLE MOISTURE BELOW 850MB. FEEL THE INSTABILITY ALONG WITH THE WEAK UPPER SUPPORT AND COLD AIR ALOFT WILL WARRANT MAINTAINING A MENTION OF SHOWERS AND THUNDERSTORMS TODAY. THE NAM AND RUC ACTUALLY SUGGEST SOME CONVECTIVE INITIATION IS POSSIBLE BY LATE MORNING ACROSS THE SAGINAW VALLEY AND THUMB. HOWEVER...A BIG LIMITING FACTOR FOR MORE WIDESPREAD CONVECTION TODAY WILL BE A CAPPING INVERSION NEAR 650MB. THE NAM IS MUCH STRONGER WITH THIS CAP COMPARED TO THE GFS. THE GFS ACTUALLY INITIALIZED MID LEVEL TEMPS BETTER THAN THE NAM...BUT STILL INDICATES A STRENGTHENING CAPPING INVERSION THROUGH THE DAY. THUS WILL KEEP POPS RELATIVELY LOW...CARRYING SCATTERED POPS IN THE SAGINAW VALLEY AND THUMB AND JUST ISOLATED TOWARD DETROIT. AS THE MID LEVEL FLOW BECOMES MORE ZONAL TONIGHT...LOW LEVEL THETA E ADVECTION WILL OCCUR ACROSS THE GREAT LAKES AS WEST-SOUTHWESTERLY LOW LEVEL FLOW STRENGTHENS. THE 00Z NCEP SUITE ARE IN STRONG AGREEMENT THAT THE BEST LOW LEVEL MOISTURE TRANSPORT WILL OCCUR ACROSS NORTHERN LOWER MI. SO WILL PLAN TO LEAVE THE FORECAST DRY WITH JUST AN INCREASE IN MID CLOUDS EXPECTED. LONG TERM...MONDAY THROUGH SATURDAY GET READY FOR AN ACTIVE WEEK WITH THE POTENTIAL OF SEVERE WEATHER AND FLOODING LOOMING FOR MOST OF THIS WEEK. OUR HIGH AMPLITUDE FLOW WILL BECOME MORE ZONAL THIS MID RANGE PERIOD AS A PERSISTENT LOW LEVEL JET AND A SERIES OF WAVES INTERACT WITH A QUASI-STATIONARY FRONT ACROSS THE HEART OF THE GREAT LAKES. SURE DETAILS AT THIS TIME ARE NEARLY IMPOSSIBLE TO FORECAST AS SUBTLE CHANGES COULD PROVIDE HUGE DIFFERENCES TO SENSIBLE WEATHER. NEVERTHELESS...NUMERICAL SUITE FOR EARLY NEXT WEEK POINT TOWARD AN IMPRESSIVE WARM THERMAL ADVECTION WITH THE NOSE OF THE INCREASING LOW LEVEL JET POINTING TOWARD THE UPPER MISSISSIPPI RIVER VALLEY THEN PROPAGATING ACROSS NORTHERN LOWER MONDAY. THIS SHOULD SET THE STAGE FOR AN MCS DEVELOPMENT AND PERHAPS ADDITIONAL ELEVATED CONVECTION ALONG THE 850MB FRONT FURTHER SOUTH THROUGH MONDAY. MEANWHILE AT THE SURFACE...WARM FRONT WILL LIFT NORTHWARD AND TIMING OF THIS ALONG WITH DAYTIME HEATING COULD PROVIDE A FOCUS FOR CONVECTION AND PERHAPS A ROUND OF SEVERE WEATHER. AT THIS TIME WE WILL RETAIN THE CHANCE FOR SHOWERS AND THUNDERSTORMS ACROSS THE NORTH IN THE MORNING THEN EXTENDING SOUTH THROUGH MONDAY AFTERNOON. TEMPERATURES AND DEWPOINTS WILL BE ON THE RISE WITH 80S AND 60S... RESPECTFULLY. THIS THEME WILL CONTINUE THROUGH THE WEEK WITH QUASI-STATIONARY BOUNDARY IN PLACE AND A SERIES OF SHORT WAVES COMING ACROSS THE ZONAL FLOW ACROSS THE NORTHERN CONUS. WITH TRAINING ECHOES AND HIGH PWATS IN PLACE...THE ADDITIONAL HAZARD WILL BE LOCALIZED FLOODING...ESPECIALLY IF WE SEE SEVERAL MCS/S TRACK ACROSS THE REGION. PERHAPS THE ONLY CONSENSUS WE ARE ABLE TO OBTAIN THIS MORNING IS A REMARKABLE TREND TOWARD SURFACE HIGHER PRESSURES BY LATE FRIDAY INTO NEXT WEEKEND. THEREFORE WE WILL EXTEND THE DRY WEATHER THROUGH THE UPCOMING WEEKEND WITH LOWER DEWPOINTS. THEN LOOKING FURTHER AHEAD...TRENDS IN THE NAO TOWARD THE POSITIVE SIDE USUALLY RESULTS IN HIGHER HEIGHTS ACROSS THE CENTER OF THE NATION INTO THE GREAT LAKES WHICH SEEMS TO BE OCCURRING IN THE GFS AND ECMWF. SO WARMER TEMPS MIGHT BE IN THE FORECAST 10 DAYS OUT. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE. LAKE ST CLAIR...NONE.
