SURFACE ANALYSIS INDICATING LOW PRESSURE OVER ONTARIO WITH A WARM FRONT NOW NORTH OF THE GREAT LAKES. OVERNIGHT MCS THAT FORMED ON TOP OF NORTHERN MICHIGAN...JUST NORTH OF ADVANCING WARM FRONT...CONTINUES TO PUSH OF QUICKLY TO THE E/SE. SECONDARY AREA OF SHOWERS/TSTMS THAT MAY HAVE FORMED ALONG OUTFLOW BOUNDARY OR MOISTURE BOUNDARY AND MOVED ALONG THE M-32 CORRIDOR ALSO EXITING THE REGION. 12Z UPPER AIR ANALYSIS INDICATING WEAK MID LEVEL RIDGE AXIS IN WISCONSIN AND WESTERN MID LEVEL FLOW ACROSS THE CWA. 700 MB CHART REVEALING +12C OR GREATER TEMPS (POSSIBLE MID LEVEL CAP) FROM WISCONSIN BACK INTO THE CENTRAL PLAINS...AND UPSTREAM CONVECTION FORMING ON THE PERIPHERY OF CAP AND RIDING OVER THE WEAK RIDGE. 850 MB CHART SHOWING +22C AND GREATER TEMPS ACROSS THE SAME REGION...AND AROUND 40 KNOT SW WINDS FROM MPX TO APX. 500 MB CHART AND WATER VAPOR IMAGERY INDICATING CONVECTIVELY INDUCED VORTICITY CENTER FROM OVERNIGHT MCS CONTINUING TO MOVE OFF TO THE EAST OF LAKE HURON...WHILE SECOND WELL DEFINED VORTICITY CENTER APPROACHING LAKE WINNIPEG (AS OF 19Z). TONIGHT...WEAK MID AND UPPER LEVEL RIDGING WILL SLIDE ACROSS THE CWA EARLY THIS EVENING WITH THE 850 AND 700 MB WINDS BECOMING MORE SW. AVN/MESOETA INDICATING 700 MB WARM NOSE (+12C) TRIES TO PUSH INTO THE REGION LATE THIS AFTERNOON AND EVENING...INCREASINGLY CAPPING THE ATMOSPHERE. THUS...ONCE ANY LINGERING ACTIVITY FALLS APART LATE THIS AFTERNOON...BELIEVE NOT MUCH WILL OCCUR THIS EVENING. CLOUD COVER WILL CONTINUE TO THIN OUT OVER THE NEXT FEW HOURS WITH THE WARMEST TEMPS OF THE DAY PROBABLY OCCURRING THIS EVENING IN MAY LOCATIONS. THEN...STRONG MID LEVEL WAVE NOW NEAR LAKE WINNIPEG WILL ADVECT INTO THE UPPER MIDWEST WITH RESULTING HEIGHT FALLS AND SUPPRESSION OF 850 AND 700 MB THERMAL RIDGES. MEANWHILE...COLD FRONT BEGINS TO PRESS INTO THE GREAT LAKES THIS EVENING. WITH THE MID LEVEL COOLING AND FRONTAL CONVERGENCE THUNDERSTORM ACTIVITY WILL CONTINUE TO INCREASE ACROSS NORTHERN WISCONSIN AND THE WESTERN U.P. KNOCKING OF THE DOOR OF EASTERN UPPER MICHIGAN BY MID TO LATE EVENING. WITH PWATS OVER 2 INCHES...LAYER CORFIDI VECTORS INDICATING SLOW PROPAGATING STORMS...HEAVY RAINFALL WILL LIKELY OCCUR IN EASTERN UPPER MICHIGAN OVERNIGHT. HOWEVER...FLOOD GUIDANCE STILL REMAINS HIGH (2-3 INCHES IN 3 HOURS) AND GREATEST RAINFALL WILL PROBABLY BE THROUGH NORTHERN MINNESOTA...AND WILL NOT ISSUE ANY FLOOD STATEMENTS AT THIS TIME. ACTIVITY WILL THEN CONTINUE TO SLOWLY SPREAD EASTWARD PRESSING INTO THE SHORELINE COUNTIES OF LAKE MICHIGAN AND ALSO FAR NORTHERN LOWER MICHIGAN LATE. SEVERE WEATHER PARAMETERS STILL LOOK GOOD WITH MID LEVEL FLOW 35 KNOTS OR GREATER LENDING TO STORM ORGANIZATION AND POSSIBLE SEVERE WIND GUSTS. MONDAY AND MONDAY NIGHT...FRONT WILL CONTINUE TO SLIDE SOUTHEAST ACROSS THE CWA DURING THE DAY...ALONG WITH MID LEVEL SHORTWAVE AND ENTRANCE REGION OF UPPER JET SLIDING THROUGH THE NORTHERN GREAT LAKES. CONVECTION SHOULD CONTINUE TO DEVELOP ALONG THE BOUNDARY AND PRESS INTO THE REST OF THE CWA DURING THE MORNING. AGAIN...WITH THE JUICY ATMOSPHERE HEAVY RAINFALL WILL BE POSSIBLE. BUT FLASH FLOOD GUIDANCE VALUES EVEN GREATER IN NORTHERN LOWER MICHIGAN SO NOT REAL CONCERNED WITH FLOODING (ASIDE FROM THE TEMPORARY URBAN SLOW RUNOFF STUFF). SEVERE WEATHER AGAIN A CONCERN WITH DECENT SHEAR PROFILES/GOOD INSTABILITY SUPPORTING SUPERCELLS AND BOWING SEGMENTS. FRONT SLIDES THROUGH THE CWA DURING THE DAY WITH DRIER AIR SLIPPING INTO THE CWA FROM THE NORTH. WILL TAPER PCPN FROM NORTH TO SOUTH DURING THE DAY...THEN LINGERING IN THE SOUTH/SOUTHEAST INTO THE EVENING. TUESDAY AND WEDNESDAY...DRIER AIR AND COOLER CONDITIONS SHOULD PREVAIL THROUGH THE MIDDLE PART OF THE WEEK...WITH HIGH PRESSURE BUILDING ACROSS THE GREAT LAKES. THURSDAY THROUGH SUNDAY...MODELS REMAIN FAIRLY CONSISTENT FOR THE END OF THE WEEK AND INTO THE WEEKEND WITH DEVELOPING AND MAINTAINING WEAK UPPER TROUGH ACROSS THE UPPER GREAT LAKES. COOLEST TEMPS WILL OCCUR THROUGH THE MIDDLE PART OF THE WEEK BUT BEGIN TO REBOUND SOME BY THURSDAY...AS HIGH PRESSURE BEGINS TO SLIDE OFF TO THE EAST AND WARM ADVECTION KICKS IN. AVN/EUROPEAN SOLUTIONS SUGGEST PCPN WILL FORM WITHIN THE WARM ADVECTION PATTERN IN THE UPPER MIDWEST...THEN TRY TO SLIP INTO THE CWA LATE THURSDAY. MUCH OF THURSDAY MAY END UP DRY AND AM INCLINED TO REMOVE SHOWER MENTION ALL TOGETHER FOR THURSDAY. FOR CONTINUITY (AND TO AVOID FLIP-FLOPS) WILL HOLD ONTO SHOWER MENTION FOR ONE MORE DAY. THEN...PIECES OF ENERGY WILL ROTATE THROUGH THE GREAT LAKES FRIDAY THROUGH SUNDAY. MODEL DIFFERENCES IN TIMING/INTENSITY WITH THIS TYPE OF PATTERN MAKES IT DIFFICULT TO PEG DOWN ANY ONE DAY AS HAVING A BETTER CHANCE FOR RAINFALL..SO WILL CONTINUE TO MENTION CHANCE OF SHOWERS/TSTMS THROUGH THE WEEKEND WITH TEMPS REMAINING ABOUT THE SAME (AT OR JUST BELOW CLIMO). THANKS MQT AND DTX FOR COORDINATION. .APX...NONE. ADAM
