NWS Detroit, MI wrote its last area forecast discussion before the first event at Jul 18, 12:06 AM EST, 54 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 106 AM EDT TUE JUL 18 2006 .AVIATION... THE CONVECTIVE COMPLEX THAT HAS BEEN GRADUALLY WORKING ACROSS SOUTHERN MICHIGAN TONIGHT HAS CREATED A VERY COMPLEX SURFACE PRESSURE PATTERN...WITH EVIDENCE OF A STRONG MESO HIGH CENTERED NEAR THE FLINT AREA. THIS WILL CREATE SOME SOME RATHER GUSTY WINDS AT THE TAF SITES FOR THE FIRST COUPLE HOURS OF THE FORECAST. THE CONVECTIVE COMPLEX WILL GRADUALLY SETTLE SOUTH OVER THE NEXT COUPLE OF HOURS. LOOKS AS THOUGH THE DETROIT AREA WILL STILL STAND THE CHANCE FOR THUNDERSTORMS THROUGH AT LEAST 09Z AS EVEN SOME LIGHTNING STRIKES HAVE BEEN OCCURRING OVER THE STRATIFORM PRECIP REGION CURRENTLY LOCATED ALONG THE I 69 CORRIDOR. LATER THE IN THE MORNING...HIGH PRESSURE TO THE NORTHWEST WILL BUILD INTO THE REGION BRINGING DRYER CONDITIONS...THEREBY ENDING THE CONVECTION AND BRINING VFR CONDITIONS TO THE TAF SITES. && .SHORT TERM...TONIGHT AND TUESDAY (ISSUED AT 325 PM) MAIN CONCERN FOR TONIGHT ARE THUNDERSTORMS AND THE POTENTIAL FOR SEVERE WEATHER. WE REMAIN RATHER STABLE AS MIXED LAYER CINH REMAINS NEAR 200 J/KG BUT THAT IS NOT THE CASE UPSTREAM. ACROSS SOUTHERN WISCONSIN MLCAPES ARE IN EXCESS OF 5500 J/KG WITH EFFECTIVE SHEAR INCREASING TOWARD 40KTS. SPC HAS ISSUED SVR WATCH 606 WITH NEAR EXPLOSIVE DEVELOPMENT SOUTH OF GRB WITH STORM TOPS NEAR 65K FEET JUST HOW MUCH OF THIS ACTIVITY WILL HOLD IN PLACE WHEN IT APPROACHES SOUTHEAST LOWER REMAINS TO BE SEEN. SURFACE CONVERGENCE ALONG THE FRONT REMAINS SUFFICIENT AND WE WILL CARRY LIKELY POPS FOR THE TRI CITIES/THUMB DOWN TO M59 CORRIDOR THROUGH THE EVENING HOURS. FRONTAL PLACEMENT SHOULD NEAR M59/8-MILE ROAD AROUND MIDNIGHT YET ATMOSPHERE SHOULD STABILIZE SOMEWHAT WITH THE LOSS OF SURFACE HEATING AND RELAXING 850MB FLOW AS IT BACKS FURTHER WEST. THEN WE WILL NEED TO MONITOR FOR TRAINING ECHOES ACROSS THE I69 CORRIDOR WITH PWATS CLIMBING NEAR 2 AS MID LEVEL FLOW BECOMES A BIT MORE PARALLEL TO THE SURFACE THIS EVENING. FFG VALUES ARE QUITE HIGH ACROSS THIS REGION WITH 3-4 NEEDED IN 1-3 HOURS AND NEARLY 4.5 IN 6 HOURS. FRONT WILL BE SLOW TO MOVE SOUTH TUESDAY MORNING...WITH AFOREMENTIONED PARALLEL FLOW REGIME...LINGERING CHANCE FOR ADDITIONAL CONVECTION ACROSS THE SOUTHERN COUNTIES BUT THAT SHOULD BE A NARROW WINDOW. HIGH PRESSURE AND A REFRESHING NORTH-NORTHEAST FLOW WILL DEVELOP TO NOT ONLY DROP BACK DEWPOINTS BUT WITH LOWER 850MB TEMPS...MORE MANAGEABLE MAX TEMPS WITH MIDDLE 80S INLAND. TEMPS WILL BE COOLER NEAR LAKE HURON WITH NORTHEAST FLOW AND THIS SHOULD KEEP THOSE VALUES INTO THE MID-UPPER 70S UNDER A MOSUNNY SKY. && .LONG TERM...TUESDAY NIGHT THROUGH MONDAY AFTER THE BRIEF HEAT WAVE...THE UPPER LEVEL FLOW IS FORECAST TO MAKE A TRANSITION BACK TO THE PREFERRED PATTERN OF THE SUMMER AS UPPER TROUGHING RE-DEVELOPS OVER THE GREAT LAKES/NORTHEAST CONUS. ONE BY ONE...MODELS HAVE COME IN LINE ON THIS IDEA DURING THE PAST FEW DAYS AND CONFIDENCE IS RATHER HIGH THAT THIS WILL OCCUR GIVEN THIS SOLID TREND. OVERALL...THIS WILL MEAN COOLER TEMPERATURES ACROSS THE LAKES. THIS WILL BE ESPECIALLY TRUE BY LATE THIS WEEK INTO THE WEEKEND AS HIGH PRESSURE SHIFTS SOUTHEAST FROM CENTRAL CANADA ON THROUGH THE GREAT LAKES. TO START THE FORECAST...WEDNESDAY AND THURSDAY WILL BE RATHER WARM STILL...ESPECIALLY FROM INTERSTATE 69 SOUTH AS THE COLD FRONT THAT MOVES SOUTH OF THE AREA ON TUESDAY SHIFTS BACK NORTH AS A WARM FRONT IN RESPONSE TO THE NEXT SHORTWAVE...WHICH IS CURRENTLY OVER BRITISH COLUMBIA. THIS FEATURE HAS MAINTAINED A PRETTY NICE REPRESENTATION ON SATELLITE. ADDITIONAL ENERGY WILL ALSO BE DROPPING SOUTHEAST THROUGH CENTRAL CANADA AROUND THE WEST SIDE OF THE DEVELOPING UPPER LOW OVER EASTERN CANADA. GIVEN THIS...EXPECT THIS SYSTEM TO BE A RATHER VIGOROUS ONE...SO EXPECT A GOOD CHANCE OF THUNDERSTORMS AS IT CROSSES THE CENTRAL LAKES IN THE THURSDAY TIMEFRAME. IN BEHIND THIS FEATURE...TEMPERATURES COOL AND HUMIDITY LEVELS DROP OFF AS THE AFOREMENTIONED CANADIAN HIGH PRESSURE BUILDS INTO THE REGION...WITH HIGHS IN THE UPPER 70S/LOWER 80S BY FRIDAY/SATURDAY. MEANWHILE...LOW TEMPERATURES WILL BE IN THE UPPER 50S/LOWER 60S. SEE NOTHING IN THE MODELS COMPELLING ENOUGH TO REMOVE THE CHANCE FOR SHOWERS/THUNDERSTORMS LATE THIS WEEKEND. MODELS ACTUALLY SHOW DECENT AGREEMENT ON BRINGING ANOTHER SHORTWAVE INTO THE AREA IN NORTHWEST FLOW PATTERN. WILL NOT CHANGE A THING AT THIS POINT. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE. LAKE ST CLAIR...NONE.
