NWS Detroit, MI wrote its last area forecast discussion before the first event at Jun 15, 7:15 PM EST, 2 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 815 PM EDT SUN JUN 15 2008 .UPDATE... A FEW THUNDERSTORMS ARE STILL EXPECTED TO DEVELOP THIS EVENING IN AN UNSTABLE ATMOSPHERE AHEAD OF THE SURFACE TROUGH AXIS...AND THE SURFACE COLD FRONT. WIDESPREAD SEVERE WEATHER IS NO LONGER EXPECTED AND THE WATCH WAS DROPPED EARLIER THIS EVENING. 00Z DTX RAOB LOOKED MORE STABLE THAN PREVIOUS RAOBS...AND DEWPOINTS ACROSS THE NORTHERN CWA HAVE BEEN DROPPING INTO THE MID 50S. STILL WATCHING UPSTREAM CLUSTER OF STORMS DEVELOPING AHEAD OF THE SURFACE COLD FRONT OVER NORTHERN WISCONSIN. THERE IS POTENTIAL FOR THIS AREA TO HOLD TOGETHER AND ARRIVE INTO SOUTHEAST MICHIGAN LATE TONIGHT. OTHERWISE...FORECASTS WERE ALL UPDATED TO REMOVE WATCH HEADLINES AND DECREASE POPS AND CLOUD COVER FOR TONIGHT. && .PREV DISCUSSION...ISSUED 727 PM EDT SUN JUN 15 2008 AVIATION... 00Z TAF PACKAGE REFLECTS VFR CONDITIONS THROUGH THE TAF PERIOD...HOWEVER WE WILL CONTINUE TO SEE A FEW SHOWERS AND THUNDERSTORMS POP UP FOR THE REMAINDER OF THE EVENING. SINCE PROBABILITY OF STORMS HITTING TERMINAL SITES IS LOW...WILL HANDLE WITH AMENDMENTS AND KEEP OUT OF PREVAILING CONDITIONS. COLD FRONT WILL PUSH THROUGH EARLY TOMORROW MORNING...FLIPPING WINDS AROUND TO THE NORTHWEST AND BRINGING IN A BROKEN LOW DECK. WINDS WILL BECOME A LITTLE GUSTY TOMORROW AFTERNOON...WITH NORTHWEST GUSTS AS HIGH AS 25 KNOTS. PREV DISCUSSION...ISSUED 419 PM EDT SUN JUN 15 2008 SHORT TERM...THIS AFTERNOON AND TONIGHT DEBRIS CLOUDS FROM OLD MCS AND STORMS THAT MOVED THROUGH SOUTHEAST MICHIGAN EARLIER THIS AFTERNOON HAVE CLEARED THE AREA. THIS HAS ALLOWED THE SUN TO COME OUT ONCE AGAIN...AND HEATING TO COMMENCE ONCE AGAIN. SPC SECTOR ANALYSIS INDICATES LOW LEVEL LAPSE RATES HAVE INCREASED TO ABOVE 8 C/KM. 18Z RAOB AND RECENT ACARS DATA SHOW THAT ATMOSPHERE IS PRETTY MUCH UNINHIBITED...WITH SURFACE BASED CAPES LIKELY NOW BETWEEN 1500 AND 2000 J/KG. 50-70 KT MID LEVEL JET IS JUST STARTING TO PUNCH INTO WESTERN LOWER MICHIGAN...AND ALREADY STARTING TO INDUCE ADDITIONAL THUNDERSTORMS TO OUR WEST. FURTHER SOUTH...THERMAL BOUNDARY FROM LAST NIGHTS COLD FRONT AND APPROACHING SURFACE TROUGH EXTENDS FROM FAR SOUTHERN MICHIGAN BACK WESTWARD INTO NORTHEAST ILLINOIS. THIS WILL ALSO BE A FOCUS FOR CONVECTION THROUGH THIS EVENING UNTIL IT IS PUSHED SOUTHEASTWARD. SEVERAL OTHER BOUNDARIES ALSO EXPECTED TO DEVELOP THROUGH THE LATE AFTERNOON AND EVENING...AND THIS WAS THE JUSTIFICATION FOR SEVERE THUNDERSTORM WATCH NUMBER 541. BOUNDARIES/MESOSCALE FEATURES CURRENTLY AROUND THAT BEAR WATCHING INCLUDE ONE COMING DOWN FROM NORTHWEST LOWER MI AND A COUPLE OF OLD OUTFLOW BOUNDARIES THAT ARE MOVING EAST OVER SOUTHWEST LOWER. UNIDIRECTIONAL AND DECENTLY STRONG WIND PROFILE ON 18Z RAOB AND DRY LOW-LEVEL AIR SUPPORT EFFECTIVE MOMENTUM TRANSFER AND PARCEL ACCELERATION DOWN TO THE SURFACE OUT OF THUNDERSTORMS...MAKING DAMAGING WINDS A THREAT THROUGH THE EVENING. FREEZING LEVELS BETWEEN 10500 AND 11000 FEET ALSO SUPPORT LARGE HAIL. COLD FRONT WILL PUSH DOWN LATE TONIGHT AS THE SURFACE TROUGH AXIS PUSHES DOWN ACROSS NORTHERN LOWER. THIS WILL ALLOW ACTIVITY TO TAPER OFF. LONG TERM...MONDAY THROUGH SUNDAY THE UPPER PATTERN WILL BE IN QUICK TRANSITION AS THE UPPER LOW THE HAS BEEN CENTERED OVER CENTRAL CANADA DIGS SOUTHEAST THROUGH THE GREAT LAKES...AND THEN MORE OR LESS STALL FROM MID/LATE WEEK FROM SOUTHERN QUEBEC INTO UPSTATE NEW YORK. THIS WILL BRING A COOLER AND UNSETTLED WEATHER PATTERN AS A SERIES OF SHORTWAVE DISTURBANCES MAKE THERE WAY THROUGH THE AREA ON THE BACKSIDE OF THIS UPPER LOW/TROUGH TO THE EAST. WILL MAINTAIN THE CHANCE OF SHOWERS/ISOLATED THUNDER ON MONDAY AND TUESDAY...WITH A CONTINUED CHANCE OF SHOWERS INTO ON INTO WEDNESDAY AS WELL. THE COLDEST OF THE AIR WILL SLIDE THROUGH THE AREA ON TUESDAY WITH GFS/NAM/ECMWF ALL SHOWING H85 TEMPERATURES DOWN TO +1C TUESDAY INTO TUESDAY NIGHT. HIGHS ON TUESDAY WILL MAINLY TOP OUT IN THE 60S WITH SOME AREAS FROM DETROIT SOUTH AROUND 70. THE TEMPERATURES WILL THEN MODERATE WEDNESDAY WITH MORE LOCATIONS REACHING 70...AND THEN MOST AREAS BACK IN THE 70S BY THURSDAY. LATE IN THE WEEK/NEXT WEEKEND...THE UPPER LOW WILL OPEN AND SHIFT TO THE EAST...LEADING TO ADDITIONAL MODERATION LATE IN THE FORECAST. EVEN SO...THE NORTHWEST UPPER FLOW PATTERN WILL PERSIST AS RIDGING OVER THE CENTRAL CONUS IS VERY SLOW IN SHIFTING EAST INTO THE GREAT LAKES...SO TRUE SUMMERLIKE CONDITIONS WILL NOT RETURN FULLY. EXPECT TEMPERATURES WELL INTO THE 70S...AND ON INTO THE LOWER 80S FRIDAY INTO SUNDAY. A PERIODIC CHANCE OF SHOWERS/THUNDERSTORMS WILL ALSO EXIST AS SHORTWAVES CONTINUE TO FEED SOUTHEAST THROUGH THE AREA IN ADVANCE OF THE UPPER RIDGE. TIMING THESE IS ALL BUT IMPOSSIBLE THIS FAR OUT. MARINE... SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THIS EVENING AS AN INCREASINGLY WARM AND UNSTABLE ENVIRONMENT MOVES IN SOUTHWEST WINDS...AND AN UPPER DISTURBANCE APPROACHES THE AREA. A STRONG COLD FRONT DROPPING SOUTHEAST THROUGH THE CENTRAL GREAT LAKES WILL MAINTAIN THE CHANCE FOR THUNDERSTORMS THROUGH TONIGHT...MAINLY FROM LAKE ST CLAIR SOUTH. THE POTENTIAL EXISTS FOR A FEW OF THESE STORMS TO BECOME SEVERE. THE REGION WILL THEN REMAIN UNDER COOL NORTHWEST FLOW THROUGH THE MIDDLE OF NEXT WEEK AS THE EXITING LOW STALLS OVER THE NORTHEAST AND HIGH PRESSURE REMAINS OVER THE CENTRAL PLAINS. && .DTX WATCHES/WARNINGS/ADVISORIES...
