NWS Detroit, MI wrote its last area forecast discussion before the first event at May 15, 2:45 PM EST, 2 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 345 PM EDT MON MAY 15 2006 .SHORT TERM... WATER VAPOR IMAGERY INDICATED OUR LARGE UPPER LEVEL CIRCULATION CENTERED ALONG THE SOUTHWEST BORDER OF OHIO WITH SOME ADDITIONAL ATLANTIC MOISTURE TRYING TO WORK INTO SOUTHEAST MICHIGAN. DIURNAL SURFACE BASED INSTABILITY HAS ALLOWED FOR THE DEVELOPMENT OF SHOWERS AND ISOLATED TO SCATTERED THUNDERSTORMS EAST OF THE ST CLAIR RIVER EARLY THIS AFTERNOON. THESE STORMS DEVELOPED A COUPLE HOURS EARLIER COMPARED TO YESTERDAY. NONE-THE-LESS...THEY WILL FOLLOW A SIMILAR PATH...PRODUCING A WIDESPREAD RAINFALL FOR THE SOUTH HALF OF THE CWA. WITH THE EARLIER START TO THE STORMS...INSTABILITY LOOKS TO BE SLIGHTLY LESS TODAY...AND WILL THUS JUST CONTINUE WITH ISOLATED THUNDERSTORM WORDING THIS EVENING. ANY THUNDERSTORM WILL BE CAPABLE OF PRODUCING SMALL HAIL AND WIND GUSTS TO 40 MPH. STORM SYSTEM TO TRACK INTO THE EASTERN GREAT LAKES/NEW YORK TOMORROW. 12Z NAM IS CONSIDERABLY FARTHER EAST THAN THE 12Z GFS...WITH THE UKMET IN THE MIDDLE. REGARDLESS...SHOULD SEE SOME SURFACE BASED INSTABILITY TOMORROW AFTERNOON AS WE BEGIN TO SLOWLY DRY OUT WITH LOW LEVEL WINDS COMING OUT OF THE NORTHWEST. WOULD EXPECT TO SEE SOME PEEKS OF SUNSHINE DURING THE AFTERNOON HOURS...SENDING TEMPERATURES INTO THE MID 60S. SPOKE OF ENERGY/SHORTWAVE DOES ROTATE ON THE BACKSIDE OF THE UPPER LOW WHICH SHOULD PROVIDE SOME DPVA ACROSS EAST HALF OF THE CWA. WITH 500 MB TEMPS NEAR -20C AND STILL SOME LINGERING SURFACE TROUGHINESS HANGING BACK ACROSS SOUTHEAST MICHIGAN...WOULD EXPECT TO SEE AT LEAST SOME SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS. && .LONG TERM...TUESDAY NIGHT THROUGH MONDAY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL LINGER INTO TUESDAY EVENING, AT LEAST UNTIL DAYTIME HEATING WEARS OUT. A CLEARING TREND WILL THEN GET UNDERWAY AFTER MIDNIGHT AS WEAK HIGH PRESSURE BUILDS IN AND MOVES QUICKLY THROUGH SE MICHIGAN BEFORE NOON ON WEDNESDAY. THE SHORT WAVE RIDGE WILL BE FORCED IN ADVANCE OF THE NEW SYSTEM DIGGING INTO THE GREAT LAKES FROM CENTRAL CANADA. TIMING ADJUSTMENTS IN THE MODELS HAVE SETTLED DOWN OVER THE LAST FEW RUNS, BUT IT STILL LOOKS LIKE DRY CONDITIONS FOR AT LEAST THE DAYTIME HOURS OF WEDNESDAY, WHICH WILL BE THE BEST DAY OF THE WEEK FOR SE MICHIGAN IN TERMS TEMPERATURES AROUND 70. PROBLEMS THAT REMAIN TO BE SORTED OUT INVOLVE THE AMOUNT OF PRECIP IN ADVANCE OF THE WAVE BY WEDNESDAY AFTERNOON. THE CHARACTER OF THE SHORT WAVE SUPPORTS MODEL SOLUTIONS THAT OFFER A SLOWER ADVANCE OF THE MOISTURE FIELD. THIS IS DUE TO THE SHEARED NATURE OF THE WAVE AROUND 500 MB AND THE EXIT REGION OF THE UPPER JET STILL TO OUR NORTH AND WEST BY 18Z WEDNESDAY, LEAVING THE ADVANCE OF A RATHER POORLY DEFINED MID LEVEL THETA-E RIDGE AS THE MAIN FORCING FOR SHOWERS WEDNESDAY AFTERNOON. THAT BEING THE CASE, THE GFS GIVES TOO MUCH CREDIT TO THE PRECIP POTENTIAL OF THIS FEATURE, ESPECIALLY DURING THE DAYTIME. THE UPPER WAVE, ASSOCIATED JET, AND SURFACE FRONTAL FEATURES WILL THEN ARRIVE IN OUR AREA WEDNESDAY NIGHT AND MOVE QUICKLY THROUGH THE AREA BEFORE SUNRISE. THIS IS WHEN SHOWERS WILL BE LIKELY AS THE COMBINATION OF FORCING ELEMENTS COME TOGETHER WITH A WELL DEFINED LOW LEVEL MOISTURE AXIS. FORECAST SURFACE DEWPOINT IN THE LOWER 50S AND 850 MB DEWPOINT AROUND 5C ARE MARGINAL FOR THUNDER BUT UPPER LEVEL COLD ADVECTION WILL HELP STEEPEN LAPSE RATES ENOUGH FOR A CHANCE OF STORMS AS 500 MB TEMPS DROP DOWN AROUND -22C. MODEL TEMP AND MOISTURE FIELDS THEN SHOW STRONG LOW LEVEL COLD AND DRY AIR ADVECTION DURING THE DAY ON THURSDAY. A MINIMAL POP IS WARRANTED FOR A CHANCE OF INSTABILITY SHOWERS UNDER THE UPPER LEVEL COLD POOL DURING THE AFTERNOON. BY THURSDAY NIGHT AND FRIDAY, THE UPPER LOW HAS TAKEN ON A CONSIDERABLY MORE CLOSED AND ENERGETIC LOOK IN THE MODELS OVER THE LAST FEW RUNS. THIS MEANS IT WILL TAKE A LITTLE LONGER TO ROTATE THROUGH LOWER MICHIGAN ON FRIDAY, KEEPING A CHANCE OF SHOWERS IN THE FORECAST, BUT STILL BE TO OUR EAST BY SATURDAY. THE NCEP ENSEMBLE MEMBERS SUPPORT A LONGER WAVELENGTH THAN THE OP GFS BETWEEN THIS UPPER LOW AND THE ONE OVER THE EASTERN PACIFIC AND SUPPORTS THE FASTER EXIT ON FRIDAY. THE RESULTING STRONGER NW UPPER FLOW WILL BE LESS SUSCEPTIBLE TO SMALLER SCALE FEATURES BUT COULD BUCKLE IN LATER MODEL RUNS BEFORE THE END OF THE WEEKEND. FOR NOW, WE WILL HOLD OFF ON ADDING POPS TO ANY OF THE DAYS FROM SATURDAY THROUGH MONDAY UNTIL SOME BETTER EVIDENCE HELPS NARROW THE TIMING DOWN. CONFIDENCE IS GOOD, HOWEVER, ON KEEPING TEMPS BELOW NORMAL AND A FEW DEGREES LOWER THAN GUIDANCE THROUGH THE PERIOD. && .PREV DISCUSSION...ISSUED 100 PM EDT MON MAY 15 2006 AVIATION... IFR LOW CLOUDS HAVE BEEN SLOW TO ERODE THIS MORNING...ESPECIALLY ACROSS THE DETROIT AREA WHERE LIGHT SHOWERS CONTINUE TO PASS THROUGH THE REGION AS THE CENTER OF THE 500 MB CIRCULATION TRACKS CLOSE TO THE SOUTHWEST OHIO BORDER. PARTIAL CLEARING NOTED OVER THE THUMB REGION...WHICH SHOULD WORK ITS WAY INTO THE MBS/FNT TAF SITES...ALLOWING FOR A PERIOD OF VFR CONDITIONS. AIRMASS WILL CONTINUE TO BECOME UNSTABLE THIS AFTERNOON...LEADING TO ADDITIONAL SHOWERS AND ISOLATED THUNDERSTORMS. DONT THINK THE COVERAGE OF THUNDERSTORMS WILL BE AS NUMEROUS AS YESTERDAY WITH A LITTLE LESS INSTABILITY AND SOME WARMING AND DRIER AIR UP AROUND 550 MB. WILL NOT INCLUDE ANY THUNDERSTORMS IN TAFS UNLESS THERE ARE BETTER INDICATIONS TAF SITES WILL BE AFFECTED. LOOKING FOR LOW CLOUDS (1000 TO 1200 FEET) TO DEVELOP LATE TONIGHT ONCE AGAIN AS LOW LEVELS REMAIN MOIST AND SURFACE TROUGH LINGERS. WINDS WILL SHIFT AROUND TO THE NORTH/NORTHWEST LATE TONIGHT/TOMORROW MORNING WHICH SHOULD HELP BEGIN TO DRY THINGS OUT...AS LOW PRESSURE FINALLY PULLS AWAY FROM THE AREA...ALBEIT SLOWLY. && .DTX WATCHES/WARNINGS/ADVISORIES...
