NWS Marquette, MI wrote its last area forecast discussion before the first event at Aug 1, 2:24 AM EST, 5 hours 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 324 AM EDT THU AUG 1 2002 MAIN FORECAST CONCERN IS SEVERE CONVECTION TODAY. VERY IMPRESSIVE LINE OF TSTMS HAVE DEVELOPED IN NE MN OVER PAST COUPLE HOURS IN RESPONSE TO LLJ CONVERGENCE ALONG H85 WARM FRONT. AT 06Z...THIS FRONT ARCHED FROM THE MN ARROWHEAD TO ACROSS THE NRN KEWEENAW PENINSULA...AND WAS MOVING NWD AS SEEN FROM ECHOES ON KDLH RADAR. GOES SOUNDINGS SHOW INCREASING LEVELS OF CAPE IN THE WESTERN U P...BUT A VERY CAPPED AMS AS WELL (H7 TEMPS ON ORDER OF 12C). THIS CONVECTION TO OUR WEST HAS SURGED AHEAD OF THE MAIN COLD FRONT (ERN ND)...ALONG WHICH CONVECTION IS FIRING AS POTENT UPR JET DRIVES EWD THRU NRN PLAINS. THUS...TODAYS CONVECTION PROBLEM LOOKS TO BE TWO-FOLD...WITH INITIAL DOSE OF A 35-40KT LLJ THIS MORNING... FOLLOWED BY FROPA THIS AFTERNOON. BOTH LARGE HAIL AND DAMAGING WINDS WILL BE POSSIBLE...BUT WINDS WILL BE PRIMARY THREAT WITH INITIAL CONVECTION AS WET-BULB ZERO HGTS REMAIN ABOVE 12KFT THIS MORNING. KDLH RADAR SHOWING TENDENCY OF LINE TO BOW ALREADY (07Z). MESOETA APPEARS TO HAVE DECENT HANDLE OF THINGS EARLY ON...HOWEVER IT IS A COUPLE HOURS FAST (MOVING PCPN INTO WRN U P BY 8Z). IT EVEN SHOWS COLD POOL MESO-HIGH IN TSTMS WAKE...WHICH MAY HELP TO DECREASE STRENGTH OF COLD FRONT. BUT...WITH MOIST AND UNSTABLE NATURE OF AMS IN PLACE...BELIEVE THIS AFFECT WILL BE MINIMAL. CURRENT DEW POINTS ACROSS THE CWA ARE IN MID 60S TO AROUND 70F. ALL INGREDIENTS LOOK TO BE IN PLACE FOR SVR EVENT...AS CAPES EXCEEDING 2K J/KG COMBINE WITH 0-3KM SHEAR IN EXCESS OF 50KTS...AND 0-3KM HELICITY NR OR SLIGHTLY ABOVE 200. SUPERCELLS WILL BE POSSIBLE. W/ PATS EXCEEDING 1.5 INCHES...AND AS LLJ BECOMES MORE PARALLEL TO WARM FRONT...FLASH FLOODING MAY ALSO BE A CONCERN. A RECENT REPORT FROM KDLH CWA INDICATED 1.5 INCHES OF RAIN IN LESS THAN AN HOUR. AVN/ETA INDICATE H5 WINDS TO NR 80KT INTO WRN UP EARLY THIS AFTERNOON AS TROF DRIVES THRU...AND FRONT WILL BE CHARACTERIZED BY STRONG THERMAL AND MOISTURE GRADIENTS (DEW POINTS NR 40F IN NE ND W/ TEMPS NR 50F). ALSO...FRONTAL WINDS WILL BE IMPRESSIVE IN ITSELF AS MOMENTUM SHOULD BRING DOWN GUSTS EXCEEDING 30KTS FOR A BRIEF TIME BEHIND THE FROPA (THOUGH GREATEST ISALLOBARIC COMPONENT IS TO SOUTH). LOOKS LIKE ONE MORE DAY OF ACTION BEFORE THINGS FINALLY QUIET DOWN TONIGHT INTO THE WEEKEND. ALSO...TEMPS WILL BE NEAR OR ABOVE NORMAL FOR ONE MORE DAY DUE TO SLOWER TIMING OF FRONT. LOWER TO MID 80S SHOULD BE ACHIEVED IN EAST HALF...AFTER MORNING LOWS NEAR 70F. TEMPS IN WEST WILL STRUGGLE TO RISE AT ALL THIS AFTERNOON. HIGH BUILDS IN FOR DRYING AND A COOLER NIGHT ACROSS THE REGION TONIGHT...THOUGH SFC PRES AND THICKNESS GRADIENTS LOOK TO SUPPORT SOME NW WIND CONTINUING OVERNIGHT. HAVE CONTINUED W/ SLGTLY ABOVE GUIDANCE LEVELS FOR LOW TEMPS. HIGHS FRI LOOK TO BE IN LOWER/MID 70S MUCH OF U P PER MESOETA SOUNDINGS AND MIXING TO NR 5KFT (H85 TEMPS OF 8-10C). AMS WILL BE QUITE STABLE...W/ DEW POINTS NR 50F AND A STRONG INVERSION BASED AT 800MB. WEAK WAA COMMENCES SAT...BUT WILL STILL BE STABLE W/ K-INDICES LESS THAN 20 AND ANTICYCLONIC FLOW W/ SFC HIGH CENTERED OVER THE CENTRAL GREAT LAKES. WILL KEEP SAT DRY...BUT SOUTHERLY LLJ EXPECTED TO PICK UP IN DAKOTAS AND MN PER BOTH AVN AND ETA. EXTENDED LOOKS GOOD W/ WARMING AND INCREASING CHANCES OF TSTMS BY SUN. NO CHANGES. .MQT...NONE. JKL
