NWS Gaylord, MI wrote its last area forecast discussion before the first event at Jun 19, 9:04 AM EST, 1 hour 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 1004 AM EDT TUE JUN 19 2012 .SYNOPSIS... ISSUED AT 444 AM EDT TUE JUN 19 2012 A WARM FRONT WILL LIFT THROUGH NORTHERN MICHIGAN TODAY AND TONIGHT BRINGING ANOTHER ROUND OF THUNDERSTORMS. THE TABLE WILL BE ALL SET FOR A HOT DAY WEDNESDAY...BEFORE A COLD FRONT SWEEPS ACROSS US LATE WEDNESDAY NIGHT AND THURSDAY FOR YET ANOTHER ROUND OF THUNDERSTORMS. COOLER WEATHER WILL THEN LEAD US INTO THE UPCOMING WEEKEND...WHEN A POTENTIALLY STRONGER COLD FRONT RESULTS IN ANOTHER CHANCE FOR SHOWERS AND STORMS...AND POSSIBLY MUCH COLDER TEMPERATURES FOR THE NEXT WORK WEEK. && .UPDATE... ISSUED AT 1001 AM EDT TUE JUN 19 2012 STILL MONITORING STEADILY APPROACHING MCS...ALREADY PUNCHING INTO NORTHWEST LAKE MICHIGAN. REPORTS OF DAMAGING WINDS AND LARGE HAIL BACK ACROSS THE BIG POND AS COMPLEX RUNS ALONG TIGHT 850MB MOISTURE GRADIENT. ALTHOUGH MOST GUIDANCE WOULD ARGUE OTHERWISE...EAST DIRECTED OFF THE DECK VAD WIND PROFILES...TIGHT 850MB MOISTURE GRADIENT ALIGNING WEST/EAST ALONG AND JUST NORTH OF THE M-32 CORRIDOR...AND SIMPLE EAST INERTIA OF COMPLEX ALL SUPPORT AT LEAST SOME MAINTENANCE OF THIS SYSTEM AS IT PUNCHES INTO OUR AREA. MAIN SHOW LOOKS TO STAY ALONG AND NORTH OF M-72...WITH THE BEST THUNDER CHANCES FROM THERE UP TO THE STRAITS. ALTHOUGH SPC SLIGHT RISK FOR SEVERE REMAINS JUST TO OUR WEST...BUILDING INSTABILITY AND 30+ KNOTS OF 0-6KM BULK SHEAR ON SOUTHERN EXTENT OF 500MB SPEED MAX SUPPORT AT LEAST SOME POTENTIAL FOR ISOLATED SEVERE WIND GUSTS AND LARGE HAIL. WILL CONTINUE TO MONITOR. UPDATE ISSUED AT 707 AM EDT TUE JUN 19 2012 NOCTURNAL CONVECTION WHICH FIRED UP ALONG AND NORTH OF A WARM FRONT IN SRN MN LAST NIGHT...WAS WORKING QUICKLY EASTWARD THIS MORNING. WHILE THE FRONT IS TRYING TO LIFT NE...THE TWO STORM COMPLEXES ON IN CENTRAL WISCONSIN WERE DEVELOPING/BUILDING SOUTHEAST INTO THE THICKER MOISTURE AND INSTABILITY. THIS PUTS A FOCUS ON NRN MICHIGAN FOR ANOTHER ROUND OF SHOWERS AND STORMS...WITH LATEST TIMING TO BRING SHOWERS AND STORMS INTO NW LOWER AROUND 15Z...FOR A TWO TO THREE HOUR PERIOD. EXPECT CLOUDS TO OVERSPREAD US A COUPLE HOURS EARLIER...WITH TEMPERATURES CLIMBS OBVIOUSLY SLOWED. CONVECTIVE EVOLUTION ALWAYS A DAUNTING TASK...BUT WOULD TEND TO BELIEVE IN AT LEAST SOME FALLING APART OF THE CONVECTION WITH LOSS OF THE LLJ DRIVING THE CONVECTION. EVENTUALLY...WARM FRONT WILL LIFT NORTHWARD...WITH A GRADUAL TREND TOWARD HIGHEST CHANCES FOR SHOWERS/STORMS INTO THE UP FOR LATER TODAY. && .SHORT TERM...(TODAY THROUGH TONIGHT) ISSUED AT 444 AM EDT TUE JUN 19 2012 QUASI-STATIONARY LOW LEVEL THETA-E AXIS REMAINS DRAPED ACROSS THE AREA EARLY THIS MORNING. A FEW SHOWERS/TSTMS CONTINUE TO DEVELOP JUST SOUTH AND WEST OF THE AREA AS WARM MOIST AIR CONTINUES TO BE DRAWN NORTHWARD OVER LOW LEVEL CONVECTIVELY INDUCED COLD POOL. ANOTHER ROUND OF CONVECTION CURRENTLY DEVELOPING OVER THE UPPER MISSISSIPPI VALLEY ASSOCIATED WITH NEXT MID LEVEL VORTICITY CENTER...WHICH WILL PUSH EAST TOWARD THE AREA TODAY. AT THE SAME TIME...EASTERN GREAT LAKES RIDGE WILL AMPLIFY AND BEGIN TO PUSH WARM FRONT NORTHWARD. WILL TAKE A MIDDLE OF THE ROAD APPROACH WITH REGARD TO PCPN CHANCES...AS CONFIDENCE REMAINS QUITE LOW IN OVERALL CONVECTIVE EVOLUTION. EXPECT SOME ACTIVITY FROM THE WEST TO WORK INTO THE AREA THIS MORNING...ALTHOUGH IT STILL REMAINS UNCLEAR HOW WIDESPREAD IT WILL BE AS IT ENCOUNTERS SOMEWHAT LESS FAVORABLE DYNAMICS AND INSTABILITY. TREND SHOULD BE FOR ANY SHOWER/TSTM ACTIVITY TO SHIFT NORTH THROUGHOUT THE DAY WITH AMPLIFYING RIDGE. ISOLATED SEVERE STORM NOT OUT OF THE QUESTION GIVEN GOOD MUCAPE AND LINGERING SPEED SHEAR. LOW LEVEL THERMAL RIDGE NOSING INTO THE AREA /20C+ TEMPS AT 925MB/...WHICH COULD EASILY PUSH SOME TEMPS OVER NORTHERN LOWER INTO THE LOWER 90S. TONIGHT...UPPER RIDGING BUILDS NORTHWARD IN EARNEST AS SFC WARM FRONT LIFTS NORTHWARD THROUGH EASTERN UPPER MICHIGAN AND ULTIMATELY INTO CANADA. THERE COULD BE SOME PCPN IMPACTING NRN PARTS OF THE AREA DURING THE EVENING...BEFORE WARM FRONT SLIDES NORTH. WOULD NOT BE SURPRISED IF THE NIGHT ENDED UP COMPLETELY DRY GIVEN INCREASING AMOUNTS OF CINH ON FORECAST SOUNDINGS...BUT WILL CONTINUE TO HOLD ON TO LOW CHANCE POPS FOR EASTERN UPPER EARLY. OTHERWISE... A MILD NIGHT IS IN STORE WITH LOWS IN THE MIDDLE 60S TO LOWER 70S. .LONG TERM...(WEDNESDAY THROUGH MONDAY) ISSUED AT 444 AM EDT TUE JUN 19 2012 WEDNESDAY-THURSDAY... MID LEVEL HEIGHT RISES WILL END...AND ACTUALLY BEGIN TO FALL BY LATE WEDNESDAY. PRIOR TO THIS...A VERY WARM/HOT DAT IS IN STORE WITH AN EXPECTED ABUNDANCE OF SUNSHINE BEHIND A WARM FRONT THAT WILL BE WELL NORTH OF US. HIGH TEMPERATURES WILL HAVE NO DIFFICULTY REACHING THE LOW 90S FOR MANY AREAS...WHILE THE HIGHER TERRAIN OF INTERIOR NORTHERN LOWER...AND EASTERN UPPER MICHIGAN WILL SEE MID AND UPPER 80S. THE HEIGHT FALLS ARE EXPECTED TO ENSUE LATE IN THE AFTERNOON WITH THE ARRIVAL OF A SHARP SHORTWAVE AND COLD FRONT. THE AIR MASS WILL LIKELY BE TOO WARM AND CAPPED OFF FOR ANY CHANCE OF PRECIPITATION FOR MOST OF THE DAY...ESPECIALLY WITH NO LAKE BREEZE AND THE COLD FRONT OFF TO OUR WEST. LEFT THE SMALL CHANCES FRO SEEING THUNDERSTORMS LATE IN THE DAY...WITHIN THETA-E AXIS...BUT FEEL CHANCES FOR THUNDERSTORMS WILL FALL INTO THE HANDS OF THE COLD FRONT WHICH ARRIVES OVERNIGHT WEDNESDAY AND INTO MAYBE AS LATE AS DAYBREAK THURSDAY. FRONTAL TIMING NOT ESPECIALLY SUITED FOR A GOOD SEVERE WEATHER CHANCE...AND THE ADVERTISED MUCAPE AND THINNING RIBBON OF MOISTURE/THETA-E THROUGH THE NIGHT LEAVES MUCH TO BE DESIRED. DELAYED THE ONSET OF EXPECTED SHOWERS/STORMS. CHANCES PERSIST INTO THURSDAY...BUT IMPROVING WEATHER THROUGH THE DAY FROM NW TO SE WITH INCREASING SUN...DRIER AND LESS HUMID AIR. HIGHS IN THE 70S AND LOWER 80S. FRIDAY AND THE WEEKEND... SHORTWAVE CLOSES OFF OVER HUDSON BAY WHILE RIDGING BUILDS INTO THE ROCKIES/HIGH PLAINS. THIS TRANSITIONS US INTO A COOLER NW FLOW ALOFT AND IN THE PATH OF SHORTWAVES DIVING INTO THE NORTH WOODS. THE FIRST WAVE HAS SOME QUESTIONS SURROUNDING IT'S POTENCY. THE MORE AGGRESSIVE GFS WANTS TO SPREAD IN SOME RAIN SHOWERS...BUT NOT FINDING ALL THAT MUCH SUPPORT FOR THIS SOLUTION IN OTHER DATA SETS. THUS...WILL NOT INTRODUCE CHANCES AT THIS POINT. A MORE VIGOROUS WAVE IS EXPECTED OVER THE WEEKEND...TIED TO WHAT COULD BE A STRONG COLD FRONT. AM STILL BUYING INTO THE CHANCE FRO SHOWERS AND MAYBE EVEN THUNDERSTORMS HERE...UNFORTUNATELY FOR THE WEEKEND. TEMPERATURES WILL BE RATHER SEASONABLE OVER THE WEEKEND...MAINLY IN THE 70S. NEXT WORK WEEK...LATEST ECMWF IS SUGGESTING A DOWNRIGHT CHILLY WEATHER PERIOD. THE COLD FRONT IS AGREED TO HAVE RUSHED THROUGH US BY MONDAY...WITH HIGH PRESSURE AND NORTHERLY WINDS DROPPING INTO THE GREAT LAKES. WHILE THE RIDGING STRENGTHENS IN THE HIGH PLAINS WITH HOT TEMPERATURES THERE...THE DEEPENING NORTHERLY FLOW FOR THE GREAT LAKES WILL ALLOW THE CLOSED HUDSON BAY LOW TO DROP INTO THE EASTERN HALF OF THE COUNTRY. ECMWF HAS A MORE AMPLIFIED PATTERN AND WANTS TO SETTLE THIS CLOSED LOW IN RIGHT OVER THE TOP OF US WITH SCATTERED AFTERNOON RAIN SHOWERS AND H8 TEMPS FALLING TO +2C! GFS IS A LITTLE MORE TEMPERED...BUT STILL CHILLY...KEEPING THE DIURNALLY DRIVEN PRECIPITATION JUST TO OUR EAST. WILL RIDE THE SHIP OF NOT INTRODUCING AFTERNOON RAIN SHOWERS JUST YET AND KEEPING HIGHS IN THE LOWER HALF OF THE 70S FOR NOW. WOULD RATHER GET A FEEL FOR NEW DATA ROLLING IN OVER THE NEXT COUPLE OF DAYS. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z WEDNESDAY MORNING) ISSUED AT 707 AM EDT TUE JUN 19 2012 A WARM FRONT WILL LIFT THROUGH NRN MICHIGAN TODAY AND TONIGHT WITH AN OVERALL SOUTH TO SOUTHWEST WIND FLOW THROUGH TONIGHT. ALL OF THE AVIATION ISSUES WILL BE IN THE NEAR TERM...WITH SHOWERS AND STORMS IN CENTRAL WISCONSIN RACING THIS WAY BETWEEN 15-19Z. STRONGEST COMPLEX WILL BE HEADING TOWARD TVC/MBL AROUND 15Z...WITH AT LEAST SOME WEAKENING EXPECTED...ALTHOUGH DAMAGING WINDS ARE NOT OUT OF THE QUESTION. ALSO...TEMPORARY IFR/MVFR CIGS VSBYS AT LEAST A DECENT BET...DID NOT GET TOO SPECIFIC WITH THE TAFS JUST YET...AS EXACT/BETTER PLACEMENT OF STRONGER STORMS CAN BE GLEANED IN THE NEXT HOUR OR SO. EVENTUALLY...THE WARM FRONT LIFTS NORTH AND VFR/HUMID QUIET CONDITIONS ARE EXPECTED TO DEVELOP. && .MARINE... ISSUED AT 444 AM EDT TUE JUN 19 2012 NO NEAR TERM MARINE ISSUES TO BE CONCERNED WITH OUTSIDE OF SCATTERED THUNDERSTORMS THAT ARE EXPECTED TO TRAVERSE THE NRN GREAT LAKES TODAY. WINDS WILL REMAIN BELOW ADVISORY CRITERIA AS A WARM FRONT WILL BLAST THROUGH TONIGHT. WINDS JUST OFF THE WATER SURFACE WILL INCREASE SIGNIFICANTLY...BUT THE HIGH STABILITY IS EXPECTED TO KEEP WIND SPEEDS BELOW ADVISORY LEVELS. A COLD FRONT WILL CROSS LATE WEDNESDAY NIGHT AND THURSDAY MORNING...WHICH MAY RESULT IN A BRIEF PERIOD OF SMALL CRAFT WINDS. OF COURSE WINDS CAN ALWAYS BE ERRATIC AND GUSTY IN AND AROUND THUNDERSTORMS. HIGH PRESSURE SETTLES IN THURSDAY NIGHT AND FRIDAY. && .APX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LH...NONE.
