NWS Detroit, MI wrote its last area forecast discussion before the first event at Jun 17, 11:49 AM EST, 11 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 1249 PM EDT TUE JUN 17 2014 .AVIATION... //DISCUSSION... MID-LEVEL WAVE TRAVERSING THE GREAT LAKES IS PRODUCING CONVECTION ACROSS THE FAR NORTH BUT ADDITIONAL DEVELOPMENT THROUGH THE MORNING HAS BEEN NON-EXISTENT. STILL, AS DIURNAL HEATING CONTINUES THERE REMAINS A CHANCE FOR THUNDERSTORMS TO IMPACT THE AIRFIELDS THROUGH THE MID-AFTERNOON HOURS THOUGH CONFIDENCE HAS DECREASED. OTHERWISE, GUSTY SOUTHWEST WINDS WILL PERSIST INTO THE AFTERNOON GUSTING TO NEAR 30 KNOTS AT TIMES. WIND WILL SHIFT TO A MORE WESTERLY DIRECTION BY AROUND 20Z BUT WILL CONTINUE TO GUST UNTIL THE LOSS OF DIURNAL HEATING THIS EVENING. ADDITIONAL SHOWER AND THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE AFTER MIDNIGHT. //DTW THRESHOLD THREATS... * LOW CONFIDENCE THUNDERSTORMS WILL IMPACT THE AIRPORT THIS AFTERNOON. * LOW CONFIDENCE IN CEILINGS AOB 5KFT, MAINLY INVOF TSTORMS && .PREV DISCUSSION...ISSUED 1021 AM EDT TUE JUN 17 2014 UPDATE... CAPPING AND WEAK LOW-LEVEL CONVERGENCE HAVE INHIBITED SOUTHWARD DEVELOPMENT OF THIS MORNING'S CONVECTION AS A REMNANT MCV PROPAGATES ACROSS THE GREAT LAKES. ALTHOUGH DEVELOPMENT WILL STILL BE POSSIBLE ACROSS THE EASTERN HALF OF THE AREA THROUGH THE EARLY AFTERNOON AS DIURNAL HEATING INCREASES, THE DELAY IN DEVELOPMENT WILL LIMIT THE POTENTIAL FOR ORGANIZATION CAPABLE OF PRODUCING A HIGHER END/MORE WIDESPREAD SEVERE THREAT. STILL, MODERATE STRENGTH WIND FIELD AND STEEP MID-LEVEL LAPSE RATES WILL PRESENT AN ISOLATED THREAT THAT WILL BE MAXIMIZED FURTHEST EAST. AS SUCH, THE FORECAST HAS BEEN UPDATED TO REFLECT A REDUCED THREAT OF SEVERE WEATHER AND HIGH TEMPS HAVE BEEN BUMPED UP A TOUCH CLOSER TO 90. PREV DISCUSSION...ISSUED 703 AM EDT TUE JUN 17 2014 UPDATE... THE REMNANT MCS ACTIVITY EARLIER THIS MORNING RAPIDLY LIFTED ACROSS NORTHERN AND CENTRAL LOWER MI. MEANWHILE...A VERY FAST MOVING MCV WHICH ORIGINATED FROM IOWA HAS BEEN RACING ACROSS SE WI OVER THE LAST HOUR AND LOOKS TO BE HEADING FOR CENTRAL LOWER MI LATER THIS MORNING. ADDITIONAL MID LEVEL HEIGHT FALLS FROM THIS WAVE AND BUILDING INSTABILITY DURING THE MORNING AND EARLY AFTERNOON REMAINS SUPPORTIVE OF A CHANCE OF SEVERE WEATHER AND THE CURRENT SCATTERED TO NUMEROUS POPS. A FORECAST UPDATE WILL BE ISSUED MAINLY TO REFRESH THE MORNING WORDING. PREV DISCUSSION...ISSUED 336 AM EDT TUE JUN 17 2014 SHORT TERM...TODAY AND TONIGHT ATTENTION THIS MORNING IS OBVIOUSLY FOCUSED ON THE FORWARD PROPAGATING MCS EXTENDING FROM THE WI/LAKE MI SHORELINE TO NW IL AS OF 07Z. STRONG LOW-MID LEVEL MOISTURE TRANSPORT AHEAD OF THIS COMPLEX AND A PLUME OF STEEP MID LEVEL LAPSE RATES EXTENDING FROM IOWA INTO SRN MI HAS BEEN SUSTAINING THE CONVECTION AS IT ADVANCES EAST. OVERALL...THE INTENSITY OF THE CONVECTION HAS WEAKENED THE LAST COUPLE OF HOURS AS THE IMMEDIATE DOWNSTREAM INSTABILITY IS RATHER MARGINAL ATTM. THE SATELLITE/RADAR COMPOSITE SHOW AT LEAST A COUPLE MCVS OVER WI. THE STRONGEST OF WHICH IS EXPECTED TO ADVANCE INTO THE STRAITS REGION BY LATE MORNING...WITH ANOTHER IMPULSE LIFTING INTO NRN LOWER MI. THESE WAVES WILL INVOKE SOME SUBTLE MID LEVEL HEIGHT FALLS ACROSS SE MI LATER THIS MORNING INTO AFTERNOON. THEY WILL ALSO TIGHTEN THE THICKNESS GRADIENT WHICH WILL INCREASE THE MID LEVEL WIND FIELD. DECREASING INSTABILITY ACROSS SRN MI THIS MORNING IS EXPECTED TO SUSTAIN THE UPSTREAM CONVECTION TO SOME DEGREE AND ALLOW IT PROGRESS INTO PORTIONS OF SE MI. WITH SOME SLIGHT DECREASE IN FORWARD SPEED NOTED ON UPSTREAM RADAR...STORMS SHOULD NOT MOVE INTO THE AREA UNTIL MID-LATE MORNING /POSSIBLY EARLY AFTERNOON IN METRO DETROIT/. SFC DEWPOINTS ACROSS FAR SW LOWER MI HAVE RISEN INTO THE UPPER 60S. CONTINUED LOW LEVEL MOISTURE TRANSPORT SHOULD BRING MID-UPPER 60 SFC DEWPOINTS INTO SE MI DURING THE COURSE OF THE MORNING. WITH THE UPSTREAM STORMS EXPECTED TO SLOW AND WEAKEN A BIT...THIS WILL PROVIDE AN OPPORTUNITY FOR MODEST DESTABILIZATION ACROSS SE MI /0-1KM ML CAPE POSSIBLY REACHING 1500-2K J/KG BY EARLY AFTERNOON/. MODEL SOUNDINGS SUGGEST GOOD CAPE DENSITY WITH 0-6KM BULK SHEAR AROUND 40KTS. THUS LINEAR CONVECTION CAPABLE OF DAMAGING WINDS AND LARGE HAIL WILL BE POSSIBLE. GOOD CYCLONIC CURVATURE IN THE LOWEST 3KM ALSO SUGGEST SOME EMBEDDED SUPERCELLS WILL BE POSSIBLE. SOME DECREASE IN COVERAGE OF CONVECTION IS EXPECTED LATER THIS AFTERNOON INTO EVENING IN THE WAKE OF THE EARLY DAY CONVECTION. MODEL SOLUTIONS ALSO SUGGEST SOME SUBTLE MID LEVEL HEIGHT RISES WHICH COULD LEAD TO SOME CAPPING. THE LOW LEVEL SW FLOW ACROSS THE MID MS AND WRN OH VALLEY WILL STRENGTHEN TONIGHT...WITH GOOD CONVERGENCE BECOMING FOCUSED ACROSS SW LOWER MI. MODEL SOLUTIONS SUGGEST SOME DEGREE OF AN E-W LOW LEVEL CONVERGENT AXIS /EITHER FROM EARLIER CONVECTIVE OUTFLOW OR A SECONDARY WARM FRONT/. A STRONGLY UNSTABLE ENVIRONMENT ACROSS THE OHIO VALLEY SHOULD BE TRANSPORTED NORTHWARD INTO SRN MI. MODEL SOUNDINGS FOR TONIGHT AGAIN SUGGEST GOOD CAPE DENSITY WITH 0-3KM MU CAPE OF 2K TO 2500 J/KG. THIS WILL RAISE THE RISK OF ADDITIONAL SEVERE WEATHER DURING THE NIGHT. THERE LOOKS TO BE A POTENTIAL FOR AN UPSTREAM SHORT WAVE IMPULSE/S/ TO ENHANCE COVERAGE OF CONVECTION. THE UNCERTAINTY IN THESE FEATURES AT THIS POINTS SUGGESTS JUST SCATTERED POPS FOR NOW. THE E-W ORIENTATION OF THE LOW LEVEL CONVERGENCE AND HIGH AMBIENT MOISTURE ALSO RAISES A RISK OF LOCALIZED FLASH FLOODING. LONG TERM...WEDNESDAY THROUGH MONDAY COLD FRONT TRAILING LOW PRESSURE TRACKING THROUGH EASTERN CANADA WILL CONTINUE TO DROP SLOWLY SOUTHWARD THROUGH LOWER MICHIGAN WEDNESDAY AND WEDNESDAY NIGHT. FRONT WILL NOT BE PARTICULARLY STRONG...BUT WILL SEE SOME INCREASED CONVERGENCE/WEAK FGEN ALONG THE BOUNDARY AS SOUTHERLY FLOW ALSO INCREASES OVER THE CORN BELT AND SOUTHERN GREAT LAKES AS LOW PRESSURE LIFTS THROUGH THE PLAINS. MAIN IMPACT OF THIS BOUNDARY WILL BE TO SERVE AS A FOCUS POINT FOR CONVECTION...AS WELL AS A PATH FOR UPSTREAM CONVECTION AND MCV'S TO RIDE OVER. GOOD POTENTIAL EXISTS FOR A MORNING SHOWERS AND THUNDERSTORMS ONCE AGAIN...BOTH FROM ACTIVITY THAT INITIATES OVER THE GREAT LAKES TONIGHT...AND FROM DEVELOPMENT UPSTREAM AS A 40-50KT LOW-LEVEL JET FOCUSES OVER IOWA AND ILLINOIS LATE TONIGHT...MAINTAINING CONVECTION THAT IS SUPPOSED TO DEVELOP LATE TODAY/TONIGHT OVER SD/NE/IA/MN. SIMILAR TO TODAY...ADDITIONAL DEVELOPMENT WILL THEN BE POSSIBLE LATER IN THE DAY AND OVERNIGHT AS THE FRONT DROPS SLOWLY SOUTH THROUGH THE AREA. AVAILABLE INSTABILITY WILL DEPEND LARGELY ON RECOVERY AFTER THE POSSIBLE EARLY DAY ROUND OF SHOWERS/TSTORMS. IF TEMPS IN THE MID 80S AND DEWPOINTS IN THE UPPER 60S ARE REALIZED...SB CAPE VALUES COULD RISE TO AROUND 3000 J/KG ALONG AND SOUTH OF THE I-69 CORRIDOR. WILL STILL NEED TO WATCH POTENTIAL FOR A CAP TO DEVELOP AS SHORTWAVE RIDGING AMPLIFIES OVER THE WESTERN GREAT LAKES. MODEL FORECAST SOUNDINGS SHOW THIS CAP MAINLY BETWEEN 2-3KFT...LOW ENOUGH TO BE ERODED BY A COLD POOL FROM CONVECTIVE COMPLEXES. THE FRONT LOOKS TO BECOME STALLED OVER FAR SOUTHERN MICHIGAN LATE WEDNESDAY NIGHT INTO THURSDAY AS UPPER WIND FIELD WEAKENS IN RESPONSE TO UPPER RIDGING BUILDING INTO THE WESTERN AND CENTRAL GREAT LAKES. THIS WILL ALLOW STORM TRACK AND AXIS OF GREATEST INSTABILITY TO SHIFT SOUTHWARD...ESPECIALLY BY THURSDAY. MODEL FORECAST SOUNDINGS ALSO SUPPORT THE IDEA OF THE CAP STRENGTHENING AS THE SHORTWAVE MID-LEVEL RIDGE AMPLIFIES AND SLIDES OVERHEAD. UPSTREAM DEVELOPMENT AND CONVECTIVE WAVES WILL STILL PROVIDE THE THREAT FOR SHOWERS AND THUNDERSTORMS HOWEVER...AND THIS MAY BECOME THE PRIMARY CONVECTIVE MODE AS THE CAP STRENGTHENS. WEAKER WIND FIELD WILL BRING A DECREASE IN WIND SHEAR...HELPING LESSEN THE CHANCES FOR WIDESPREAD SEVERE WEATHER. STILL...SB CAPE VALUES (AND HIGHER DEWPOINTS) CONTINUE TO LOOK HIGH ENOUGH SOUTH OF THE I-69 CORRIDOR TO SUPPORT AN ISOLATED SEVERE STORM OR TWO. UPPER RIDGING WILL BREAK DOWN OVER THE AREA THURSDAY NIGHT AND FRIDAY AS AN UPPER/SURFACE LOW PRESSURE MOVES INTO MANITOBA AND MINNESOTA. THIS WILL ALLOW THE FRONT TO LIFT BACK NORTHWARD ACROSS MICHIGAN AS A WARM FRONT...TAKING A MORE NORTHWEST TO SOUTHEAST ORIENTATION. THIS WILL ALLOW COVERAGE OF THUNDERSTORMS TO INCREASE AGAIN BY FRIDAY. STILL A LOT OF MODEL DIFFERENCES...BUT THIS SYSTEM LOOKS TO DROP SLOWLY THROUGH THE GREAT LAKES OVER THE WEEKEND AND INTO MONDAY KEEPING AN ACTIVE WEATHER PATTERN OVER THE AREA. GFS IS SLOWER WITH THE SYSTEM THAN THE EURO/GEM...AND INTRODUCED CHANCE POPS FOR MONDAY TO ACCOUNT FOR THE SLOWER SOLUTIONS. MARINE... A STORM COMPLEX IS EXPECTED TO MOVE ACROSS THE CENTRAL AND SOUTHERN GREAT LAKES DURING THE FIRST PART OF TODAY. ADDITIONAL ROUNDS OF RAIN AND THUNDERSTORMS ARE THEN EXPECTED THROUGH THURSDAY AS A WEAK COLD FRONT SLOWLY DROPS DOWN THROUGH THE CENTRAL GREAT LAKES AND STALLS OVER SOUTHERN MICHIGAN. SOME OF THESE STORMS MAY BE STRONG TO SEVERE THROUGH THURSDAY. ADDITIONAL SHOWERS AND THUNDERSTORMS ARE THEN POSSIBLE THURSDAY NIGHT THROUGH FRIDAY AS THE FRONT LIFTS BACK NORTHWARD IN ADVANCE OF AN APPROACHING LOW PRESSURE SYSTEM. && .DTX WATCHES/WARNINGS/ADVISORIES...
