NWS Detroit, MI wrote its last area forecast discussion before the first event at Jul 4, 12:13 AM EST, 1 hour 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 113 AM EDT TUE JUL 4 2006 .AVIATION... MAINLY VFR CONDITIONS EXPECTED ACROSS THE REGION THROUGH THE TAF FORECAST PERIOD...WITH THE EXCEPTION OF SOME PATCHY MVFR/IFR IN THUNDERSTORMS DURING THE FIRST FEW HOURS OF THE FORECAST. MVFR CLOUDS WILL ERODE ALONG WITH WEAKENING CONVECTION...HOWEVER...WEAKER GRADIENT FLOW AND SOME BREAKS IN CLOUD COVER 09-12Z WILL RESULT IN PATCHY MVFR FOG CONDITIONS FOR THE SAME AREA. MAIN AREAS OF CONVECTION WILL FOCUS OVER THE NORTHERN OHIO VALLEY OVERNIGHT ALONG A STATIONARY FRONT...WHICH WILL STRUGGLE TO MOVE NORTHWARD...AND ALONG THE COLD FRONT AS IT SLIPS SOUTH THROUGH THE CENTRAL GREAT LAKES OVERNIGHT. THE LOW LEVEL JET AND MOISTURE AXIS WILL SLIP A LITTLE FARTHER TO THE SOUTHEAST AND LIMIT MUCH NORTHWARD ADVANCE OF CONVECTIVE ACTIVITY SOUTH OF M 59. MODELS INDICATE COLD FRONT A LITTLE SLOWER TO MOVE INTO THE OHIO VALLEY TODAY...WITH THREAT OF SCATTERED CONVECTION IN DET/DTW AREA UNTIL AROUND 16Z. THEN VFR CONDITIONS THROUGH THE REMAINDER OF THE TAF PERIOD AS DRIER AIR FILTERS INTO THE REGION ON NORTH TO NORTHWEST LOW LEVEL FLOW. && .SHORT TERM...TONIGHT AND TUESDAY TWO MAIN FEATURES OF INTEREST FOR THE OVERNIGHT FORECAST. THE FIRST IS AN UPPER LEVEL TROUGH MOVING OVER ONTARIO BRINGING A COLD FRONT SOUTH OVER LOWER MICHIGAN. THE SECOND IS CONVECTION FIRING OVER ILLINOIS ALONG THE STALLED OUT WARM FRONT THAT IS LOCATED JUST SOUTH OF THE STATE. AS THESE TWO SYSTEMS INTERACT...GOOD MOISTURE CONVERGENCE WILL SET UP FROM NORTHERN ILLINOIS TO SOUTHWEST LOWER MICHIGAN. AT THIS TIME THUNDERSTORMS CONTINUE TO DEVELOP WESTWARD ALONG THE BOUNDARY WHERE BETTER INSTABILITY IS LOCATED BUT AS THE LOW LEVEL JET INTERACTS WITH THE INCREASING MOISTURE CONVERGENCE SHOULD START TO SEE MORE DEVELOPMENT OVER SOUTHWEST LOWER AND NORTHERN INDIANA. THE BIG QUESTION FOR THE FORECAST IS WHERE THIS BOUNDARY WILL SET UP AS THE OTHER FRONT DROPS SOUTH. HEAVY RAIN IS POSSIBLE ALONG THIS BOUNDARY WHERE PRECIPITABLE WATER VALUES ARE AROUND 1.80 INCHES AND K INDEX IN THE UPPER 30S. MODELS ARE INDICATING THAT THIS BOUNDARY WILL LIFT AS FAR NORTH AS I-94 OVERNIGHT BEFORE THE LOW LEVEL JET VEERS...FORCING THUNDERSTORMS SOUTHEAST TOWARDS OHIO. FLASH FLOOD GUIDANCE FOR LENAWEE AND MONROE COUNTIES IS AROUND 3 INCHES AND THE SITUATION WILL HAVE TO BE MONITORED OVERNIGHT. THESE THUNDERSTORMS ARE GENERALLY EXPECTED TO BE ELEVATED BY THE TIME THEY REACH SOUTHEAST MICHIGAN WITH SOME SMALL HAIL POSSIBLE AS GOOD SHEAR THROUGH THE COLUMN MAY SUPPORT STRONG UPDRAFTS. MEANWHILE THE FRONT DROPPING DOWN FROM THE NORTH SHOULD REACH THE TRI-CITIES AROUND MIDNIGHT. SHOWALTER INDICES WILL ONLY BE DOWN AROUND -1C WITH ANY AVAILABLE CAPE DECREASING QUICKLY AFTER SUNSET. AS THE SURFACE LOW MOVES INTO ONTARIO...MID-LEVEL FLOW BECOMES ORIENTED NEARLY PARALLEL TO FRONT AND WILL LOOK FOR STORMS TO LOSE STRENGTH BEFORE REACHING SOUTHEAST MICHIGAN. ALTHOUGH THERE WILL STILL BE PLENTY OF SHEAR...DO NOT EXPECT STORMS ASSOCIATED WITH THIS BOUNDARY TO BE SEVERE. ON TUESDAY...NAM/GEM/LOCAL WRF/UKMET ALL IN AGREEMENT THAT FRONTAL BOUNDARY WILL BE SOUTH OF THE STATE ON TUESDAY. COOLING BELOW 700MB WILL SET UP A CAP IN THE ATMOSPHERE AND HAVE REMOVED THUNDERSTORMS FROM THE FORECAST. THE MUCH DRIER AIRMASS IN PLACE OVER THE NORTHERN PLAINS WILL ADVECT SOUTH WITH LESS HUMIDITY AND NEAR NORMAL TEMPERATURES FOR THE HOLIDAY. && .LONG TERM...TUESDAY NIGHT THROUGH MONDAY THE UPPER PATTERN ACROSS NORTH AMERICA WILL CONTINUE TO UNDERGO SOME AMPLIFICATION HEADING INTO THE MIDDLE OF THE WEEK. HEIGHTS ARE FORECAST TO RISE ACROSS WESTERN CANADA WHILE THE UPPER LOW TO THE NORTH OF THE GREAT LAKES HEADS INTO SOUTHERN QUEBEC. THIS WILL ALLOW THE LARGE AREA OF HIGH PRESSURE OVER CENTRAL CANADA TO BUILD INTO THE WESTERN GREAT LAKES BY MID WEEK...BRINGING MUCH COOLER AND DRYER AIR INTO SE MICHIGAN BEGINNING TUESDAY NIGHT. THE 12Z GFS...NAM...GLOBAL AND UKMET ARE ALL NOW SUGGESTIVE OF A FAIRLY SHARP MID LEVEL TROUGH AXIS SWINGING THROUGH SOUTHERN MICHIGAN WEDNESDAY NIGHT AS THE MEAN LONG WAVE TROUGH OVER EASTERN NORTH AMERICA AMPLIFIES. 500MB TEMPS ARE FORECAST TO DROP TO -18C UNDERNEATH THE ASSOCIATED COLD POOL ALOFT. NAM AND GFS DO INDICATE SOME MOISTURE NEAR 850MB WHICH SHOULD EVOLVE INTO A SCATTERED TO BROKEN CU FIELD WITHIN THE LOW LEVEL THERMAL TROUGH OVER THE STATE ON WEDNESDAY. DESPITE THE ARRIVAL OF THE COLD AIR ALOFT...WILL CONTINUE WITH A DRY FORECAST AT THIS TIME. THE BIGGEST LIMITING FACTOR WILL BE THE TIMING OF THE COLDEST AIR ALOFT ARRIVING AFTER PEAK HEATING ON WEDNESDAY. THE DEPTH OF MOISTURE IS ALSO EXPECTED TO BE FAIRLY LEAN AND THERE IS VIRTUALLY LITTLE TO NO SURFACE BASED CAPE ON MODEL SOUNDINGS. THE 12Z OPERATIONAL MODEL SUITE INDICATE THE LONG WAVE TROUGH TO REMAIN RATHER PROGRESSIVE LATE IN THE WEEK. THIS WOULD ALLOW THE MID LEVEL RIDGE TO BUILD INTO THE WESTERN GREAT LAKES...WITH SURFACE HIGH PRESSURE IN PLACE OVER THE SOUTHERN GREAT LAKES. HAVE SOME CONCERN WITH A FEW GFS ENSEMBLE MEMBERS FORECASTING THE DEVELOPMENT OF A CUT OFF LOW JUST EAST OF THE STATE. WILL HOWEVER FOLLOW THE 00Z AND 12Z MODEL CONSENSUS AND ENSEMBLE MEANS. THIS WILL KEEP DRY CONDITIONS OVER SE MICHIGAN...WITH THE RETURN FLOW AROUND THE SURFACE HIGH AND BUILDING MID LEVEL HEIGHTS ALLOWING A STEADY WARMING TREND FRI INTO SUN. THE 00Z AND 12Z MODEL SUITE CONTINUE TO INDICATE WAVES LIFTING OUT OF THE PACIFIC NORTHWEST AND RIDING ATOP THE RIDGE TOWARD THE END OF THE LONG TERM. ENSEMBLE MEMBERS CONTINUE TO SHOW A WIDE RANGE OF TIMING AND AMPLITUDE OF THESE WAVES. GIVEN THE RATHER POOR RUN TO RUN CONTINUITY IN THE GFS...WILL FOLLOW THE MORE CONSISTENT ECMWF WHICH HOLDS HIGHER HEIGHTS OVER SE MICHIGAN THROUGH LATE NEXT WEEKEND. THIS IS IN LINE WITH THE CURRENT FORECAST OF NO PRECIPITATION WITH TEMPS AVERAGING ABOVE NORMAL. GIVEN THE LARGE SPREAD IN ENSEMBLE MEMBERS THOUGH...THERE IS STILL A RATHER HIGH DEGREE OF UNCERTAINTY HEADING INTO THE DAY 7 FORECAST. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE.
