NWS Marquette, MI wrote its last area forecast discussion before the first event at Aug 13, 2:16 PM CST, 2 hours 12 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 416 PM EDT MON AUG 13 2012 .SHORT TERM...(THIS EVENING THROUGH TUESDAY) ISSUED AT 407 PM EDT MON AUG 13 2012 WV LOOP AND RAOBS INDICATE UPPER TROUGHS FROM NORTHERN ONTARIO THROUGH THE WESTERN GREAT LAKES REGION. STRONGEST SHORTWAVES IN THE MEAN TROUGH ARE OVER NORTHERN ONTARIO AND ALSO SOUTHERN LOWER MICHIGAN. SHORTWAVE BTWN THE TWO TROUGHS AND SFC TROUGH MERGED UP WITH LAKE BREEZES OVR CNTRL UPR MICHIGAN EARLIER THIS AFTN TO KICK OFF ISOLD SHRA AND STORMS. CONVECTIVE DEPTH WAS SHALLOW...BUT RADAR ESTIMATED PRECIP AMOUNTS UP TO 1-1.5 INCHES SEEMED REASONABLE AS STORM MOTION WAS SLOW AND EVEN TRIED TO BACKBUILD OVR EXTREME SOUTH CENTRAL MARQUETTE COUNTY AS ONE STORM BRIEFLY BECAME A RIGHT MOVER. AS OF 19Z...THE MESS OF THE SYNOPTIC TROUGH AND LAKE BREEZE CONVERGENCE BOUNDARY IS ORIENTED FM ROUGHLY WATERSMEET THROUGH JUST NORTH OF CRYSTAL FALLS AND IRON MOUNTAIN AND EAST TOWARD NEWBERRY AND SAULT STE MARIE. ISOLD-SCATTERED SHRA/TSRA ARE LOCATED ALONG THE TROUGH WITH STORM MOTIONS GENERALLY ESE AROUND 15 MPH. BASED ON RADAR TRENDS AND HRRR MODEL...HIGHLIGHTED HIGHEST POPS EARLY THIS EVENING OVR SCNTRL UPR MICHIGAN...WITH DIMINISHING TREND BY LATE EVENING DUE TO LOSS OF DAYTIME INSTABILITY AND LOW-LEVEL CONVERGENCE. STILL...AT LEAST ISOLD SHRA/TSRA MAY TRY TO STICK AROUND THROUGH EVEN AFTER MIDNIGHT IN THE FAR SCNTRL WITH LINGERING WEAKER SHORTWAVE ENERGY OVERHEAD AND STEEPER MID-LEVEL LAPSE RATES AND H85-H7 MOISTURE. ALL CONVECTION SHOULD BE OUT OF CWA BY LATE TONIGHT. TEMPS OVER INTERIOR WEST MAY TRY TO FALL OFF INTO THE 40S LATE TONIGHT WITH A LOWER PWAT MIN LOCATED THERE. A BIT OF WIND AND POSSIBLE SCT-BKN MID CLOUDS SHOULD KEEP REST OF CWA IN THE 50S. ON TUESDAY...DAY STARTS OFF WITH THE SCT-BKN MID CLOUDS WITH CU BUILDUP BY LATE MORNING AS CONVECTIVE TEMPS ARE IN THE LOWER 70S. SHORTWAVE ON BACK SIDE OF LARGER SCALE TROUGH IN CNTRL SASKATCHEWAN AND/OR MANITOBA FCST TO SLIDE INTO CNTRL CWA BY MID AFTN. GIVEN SIMILAR FCST SBCAPES IN THE 700-1000J/KG RANGE COULD SEE REPEAT PERFORMANCE OF TODAY...OR AT LEAST SOMEWHAT SIMILAR...WITH ISOLD-SCATTERED SHRA/TSRA FORMING SHORTLY AFTER CONVECTIVE TEMPS ARE REACHED. MAIN DIFFERENCE IS THE SHORTWAVE IS NOT AS STRONG AND LOW-LEVEL CONVERGENCE WILL BE STRICTLY DRIVEN BY LAKE BREEZES FM LAKE SUPERIOR/LAKE MICHIGAN. MSLP/WIND PATTERN POINTS TO AREA BTWN SAW-IMT-ESC STAND TO SEE BEST COVERAGE OF SHRA/TSRA. FREEZING LEVELS AROUND 11KFT AGL AND H85-H7 WINDS FAIRLY SIMILAR TO TODAY AS WELL...SO AGAIN COULD SEE SLOW MOVING STORMS WITH MAIN HAZARDS LIGHTNING AND HEAVY DOWNPOURS. SMALL HAIL COULD ALSO OCCUR WITH STRONGEST STORMS. CONVERGENCE WANES BY LATE AFTN SO KEPT WITH IDEA THAT POPS WILL BE OUT OF THE CWA BY EARLY TUESDAY EVENING. .LONG TERM...(TUESDAY NIGHT THROUGH MONDAY) ISSUED AT 407 PM EDT MON AUG 13 2012 TUESDAY NIGHT THROUGH WEDNESDAY AFTERNOON...THE UPPER LEVEL TROUGH WITH AXIS EXTENDING SOUTHWARD FROM CENTRAL ONTARIO THROUGH THE EASTERN HALF OF UPPER MI AND INTO THE WESTERN HALF OF LOWER MI WILL SHIFT EASTWARD OVERNIGHT...REACHING THE LOWER GREAT LAKES BY WEDNESDAY AFTERNOON. AS THIS TROUGH SHIFTS EASTWARD A SURFACE AND WEAK UPPER LEVEL RIDGE WILL BUILD INTO THE UPPER GREAT LAKES REGION...BRIEFLY BRINGING AND END TO THE CHANCES OF PRECIPITATION. WEDNESDAY EVENING THROUGH FRIDAY NIGHT...AS THE SURFACE RIDGE AND UPPER LEVEL RIDGE BEGIN TO SHIFT EASTWARD TO THE LOWER GREAT LAKES ATTENTION WILL THEN TURN TO AN APPROACHING LOW PRESSURE SYSTEM CENTERED OVER NORTHERN MN...WITH ASSOCIATED UPPER LEVEL TROUGH TO THE WEST OF THE SURFACE LOW...INDICATED BY BOTH THE EC/GFS...SUGGESTING THAT THE SURFACE LOW IS EXPECTED TO INTENSIFY. THE LOW WILL PASS TO THE NORTH OF THE UPPER PENINSULA BY 12Z THURSDAY AS IT DRAGS A COLD FRONT THROUGH INTO CENTRAL UPPER MI AROUND THE SAME TIME AS INDICATED BY PLOTTING MSLP/850 THETA E/SURFACE WINDS. THE MAIN AREA OF PRECIPITATION WILL LIKELY BE PEGGED TO THE FRONT OF THE COLD FRONT AS THE FORCING APPEARS THE GREATEST ALONG THIS AREA AS SHOWN BY PLOTTING 500-300MB DIVQ ALONG WITH 1000-500 RH VALUES. MU CAPE VALUES AREA PROGGED TO BE AROUND 500-800 J/KG OVER MUCH OF THE AREA OVER THE WESTERN HALF OF THE AREA AROUND 06Z SHIFTING TO THE EAST HALF AROUND 12Z THURSDAY. 0-6 KM SHEAR VALUES ARE EXPECTED TO BE AROUND 30 TO 35 KNOTS AHEAD OF THE FRONT WITH VALUES INCREASING TO AROUND 50 KNOTS ALONG AND BEHIND THE FRONT. SHEAR VALUES BEING MARGINAL FOR SEVERE WEATHER AHEAD OF THE FRONT ALONG WITH CAPE IN THE HAIL GROWTH ZONE AROUND 100-200 J/KG WOULD INDICATE ONLY A MARGINAL THREAT OF HAIL. DCAPE VALUES ARE FAIRLY LOW WITH VALUES AROUND 100-150 J/KG DUE TO A LACK OF DRY AIR IN THE MID LEVEL. THURSDAY NIGHT THROUGH FRIDAY NIGHT THE UPPER LEVEL TROUGH WILL REMAIN OVER UPPER MI...WHILE SHIFTING EVER SO SLOWLY TO THE EAST AS THE SURFACE LOW PULLS OT THE NORTHEAST TO WESTERN QUEBEC. THE COOLER AIR WRAPPING AROUND THE BACK SIDE OF THE LOW ALONG WITH DECREASED TEMPERATURES ALOFT...AROUND 4 TO 6C AT H850...WILL HELP TO INCREASE THE CHANCE OF LAKE EFFECT SHOWERS OVER THOSE AREAS FAVORED BY NORTH WINDS. HAVE ALSO INCREASED THE WINDS OVER THE CENTRAL AND EASTERN PORTIONS OF THE LAKE AS CAA KICKS IN...EXPECT THE STRONGER WINDS TO MIX DOWN AS H850 WINDS ARE AROUND 35 KNOTS. WILL HAVE TO KEEP AN EYE ON THIS THROUGH LATER SHIFTS. SATURDAY THROUGH MONDAY...BOTH THE EC AND GFS KEEP THE UPPER LEVEL 500MB TROUGH SITUATED OVER MUCH OF THE UPPER GREAT LAKES REGION...HELPING TO KEEP ON AND OFF CHANCES OF SHOWERS IN THE FORECAST THROUGH MONDAY AFTERNOON. THE BEST CHANCE OF RAIN SHOWERS THROUGH THIS PERIOD WOULD BE MONDAY AS A SURFACE LOW APPROACHES THE AREA FROM THE WEST. MOISTURE THROUGH THIS TIME PERIOD APPEARS TO BE FAIRLY LIMITED AS A SURFACE HIGH WILL REMAIN JUST TO THE SOUTH OF THE REGION KEEPING DRY WESTERLY WINDS PUSHING INTO THE AREA. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON) ISSUED AT 225 PM EDT MON AUG 13 2012 WEAK COLD FRONT COULD TRIGGER ADDITIONAL SHRA/TSRA AT SAW THIS AFTERNOON. IWD AND CMX SHOULD REMAIN DRY. IFR/MVFR CONDITIONS WITH THE SHRA/TSRA EARLY THIS AFTN AT SAW...BUT OTHERWISE SHOULD BE VFR AT ALL THE TAF SITES. ONCE FRONT MOVES THROUGH LATER TODAY...EXPECT SCT-BKN MID CLOUDS AT ALL TAF SITES TONIGHT INTO TUESDAY MORNING WITH OVERALL LIGHT WINDS. IF SKIES CAN CLEAR OUT SOME TONIGHT MAY SEE PATCHY FOG FORM AT SAW DUE TO THE ADDITIONAL MOISTURE FROM SHRA/TSRA THAT OCCURRED EARLY THIS AFTN. SHOT AT ISOLATED SHRA ON TUESDAY AT SAW BUT THIS WOULD BE AFTER THIS TAF PERIOD. && .MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 407 PM EDT MON AUG 13 2012 QUIET MARINE WEATHER THROUGH WEDNESDAY AS HIGH PRESSURE SLIDES OVERHEAD. BY LATER THURSDAY...PASSAGE OF A STRONG COLD FRONT WILL KICK UP NORTHWEST WINDS TO 25 KTS OVER MUCH OF THE LAKE. WINDS TO 30 KTS ARE EXPECTED OVER CENTRAL AND EASTERN SECTIONS AS COLDER AIRMASS PUSHES ACROSS THE STILL WARMER WATERS OF LAKE SUPERIOR. THE UNSTABLE PROFILE WILL LEAD TO BUILDING WAVES THURSDAY NIGHT INTO FRIDAY. EXPECT THE STRONG WINDS AND HIGH WAVES TO CONTINUE INTO SATURDAY BEFORE DIMINISHING WITH ARRIVAL OF HIGH PRESSURE. EXPECT THE HIGHER WAVES TO LEAD TO AN INCREASED RISK OF RIP CURRENTS LATE THURSDAY THROUGH FRIDAY ALONG THE BEACHES OF EASTERN LAKE SUPERIOR. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN...
