NWS Gaylord, MI wrote its last area forecast discussion before the first event at Jul 27, 2:24 PM EST, 5 hours 54 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 324 PM EDT SAT JUL 27 2002 MORNING CONVECTIVE DEBRIS KEPT TEMPS FROM REACHING FULL POTENTIAL TODAY...BUT STILL A SULTRY DAY IN PROGRESS. VORT MAX OVER THE NORTHERN PLAINS BECAME CONVECTIVELY ACTIVE BY MID-MORNING IN WESTERN MN. THE EVOLUTION OF THIS SVR MCS...NOW APPROACHING NW WI...IS THE OBVIOUS FORECAST CONCERN TONIGHT. POTENTIAL FOR CONVECTION REMAINS A CONCERN THRU MONDAY...AS WARM HUMID WX PERSISTS. ETA/NGM IN FAIRLY REASONABLE AGREEMENT...THOUGH ETA HAS A BETTER HANDLE ON THE WARM FRONT MOVING INTO NORTHERN LOWER TONIGHT. WILL COMPROMISE ON THE VERY SLOW MOVING COLD FRONT...WHICH SHOULD MOVE THRU EASTERN UPPER AND INTO FAR NW LOWER MI ON SUNDAY. A SURFACE WAVE WILL DEVELOP ALONG THIS FRONT TO OUR WEST SUNDAY NIGHT...AS AN UPPER TROF APPROACHES. THE SURFACE AND UPPER WAVES WILL GIVE THE COLD FRONT THE IMPETUS IT NEEDS TO EXIT THE FORECAST AREA ON MONDAY. ALL ZONES WILL NEED SCT POPS THIS EVENING FOR POSSIBLE/EXISTING DIURNAL STORMS. WILL NEED TO WATCH FOR MULITCELL ORGANIZATION FOR THE POSSIBILITY OF A WIND THREAT...AS 500MB WINDS BECOME MARGINALLY SUPPORTIVE BY EARLY EVENING (AROUND 30KT). SO FAR...TSRA IN NE LOWER MI ARE STRAIGHT UP AND DOWN...INDICATING A LOW-SHEAR ENVIRONMENT. MN/WI MCS SHOULD CONTINUE ON A EASTWARD TRACK ALONG WITH THE PARENT SHORTWAVE. EASTERN UPPER WILL BE AFFECTED TOWARD MIDNIGHT...AND HIGH POPS IN ORDER THERE. QUESTION THERE IS HOW STRONG WILL THE STORMS BE. WIND FIELDS WILL BE MARGINALLY SUPPORTIVE OF SVR...500MB WINDS INCREASING TO 30-35KT. BUT STORMS WILL TEND TO BECOME ELEVATED AFTER NIGHTFALL...AND AS THEY ENCOUNTER THE MARINE-INFLUENCED AIRMASS OVER EASTERN UPPER. WE SAW THIS PAST SUNDAY NIGHT HOW MUCH THAT CAN DISRUPT EVEN A WELL-ORGANIZED MCS. THUS SVR THREAT OVERNIGHT IN EASTERN UPPER SEEMS ON THE SMALL SIDE. FOR NORTHERN LOWER OVERNIGHT...CONCERN FOCUSES ON INCREASING LOW LEVEL THETA-E ADVECTION AS SURFACE WARM FRONT LIFT NORTH INTO SOUTHERN LOWER...AND 850MB WARM FRONT MOVES THRU NORTHERN LOWER. EXPECT LOW-LEVEL LIFT TO BE SUFFICIENT TO INITIATE TSRA OVER MUCH OF NORTHERN LOWER LATE EVENING INTO OVERNIGHT. WIND FIELDS INCREASE DRAMATICALLY AFTER 06Z...WITH 500MB WINDS RAMPING UP TO 50-55KT. BUT AGAIN STORMS WILL TEND TO BE ELEVATED...SO GETTING WINDS TO THE SURFACE WILL BE DIFFICULT. IN ADDITION...THOSE INCREASING WINDS REPRESENT A MID-LEVEL DRY PUNCH FROM THE WEST...POSSIBLY CUTTING OFF CONVECTION FROM WEST TO EAST OVERNIGHT JUST AS WINDS ALOFT ARE CRANKING UP. SUNDAY...MID LEVEL AIRMASS WILL BE WARMER AND DRIER THAN TODAY... MAKING THE CONVECTIVE THREAT EVEN MORE OF A DILEMMA. EVEN WITH THE EXPECTATION OF MINIMAL DEBRIS CLOUDS IN THE MORNING...THE TENDENCY TO MIX DOWN SOMEWHAT DRIER AIR IN THE AFTERNOON WILL TEND TO KEEP SOME NEGATIVE AREA IN THE SOUNDINGS ALL DAY. BUT LOW LEVEL FORCING MECHANISMS WILL BE GREATER...WITH A WEAK COLD FRONT DROPPING SOUTH INTO NORTHERN ZONES...HAVING OPPORTUNITY TO INTERACT WITH OUTFLOW BOUNDARIES FROM PREVIOUS NIGHTS CONVECTION. BELIEVE THIS WILL BE ENOUGH TO OVERCOME CIN...AND WILL CONTINUE WITH SCT TSRA ALL ZONES. SVR POTENTIAL IS SIGNIFICANT IF CONVECTION DOES DEVELOP...WITH 500MB WINDS 40-50KT AND 0-6KM BULK SHEAR 30-35KT PROVIDING GOOD SUPPORT FOR STORM ORGANIZATION AND A DAMAGING WIND THREAT. SUNDAY NIGHT...ONCE DIURNAL STUFF HAS DIED IN THE EVENING...NOT A LOT OF SUPPORT FOR ADDITIONAL PRECIP TIL VERY LATE. NEXT UPPER TROF...AND A WEAK SURFACE WAVE ALONG THE FRONT...WILL APPROACH THE WESTERN LAKES BY DAYBREAK. MOST OF THE SUPPORT WILL STAY WEST OF THIS FORECAST AREA. WILL HAVE LOW CHANCE POPS ALL ZONES...ONLY IN THE EVENING IN NE LOWER. MONDAY...PASSAGE OF SURFACE LOW AND UPPER TROF THRU THE FORECAST AREA. STRONG UPPER DIVERGENCE PROGGED IN RIGHT ENTRANCE REGION 100KT+ 200MB JET. GIVEN DYNAMICS...AND MODEL CONSISTENCY IN PROGGING THIS SYSTEM INTO THE FORECAST AREA...WILL UP POPS TO LIKELY. REST OF THE FORECAST...FAST UPPER FLOW WILL REMAIN IN PLACE...AS AN UPPER LOW DEEPENS NEAR HUDSON BAY AND HEIGHTS REMAIN HIGH IN THE SOUTHERN US. MODELS HAVING ALL SORTS OF DIFFICULTIES WITH THE RIPPLES EMBEDDED WITHIN THE WESTERLIES...TYPICAL FOR FAST-FLOW SITUATIONS. THE ECMWF...CANADIAN...AND A FEW MRF ENSEMBLE MEMBERS START TO BUCKLE THE UPPER FLOW LATE IN THE WEEK...WITH A DEEPENING TROF IN THE LAKES REGION. THE REST OF THE MODELS (INCLUDING THE BULK OF THE MRF ENSEMBLE AND DTX EXTENDED ETA) ARE MUCH LESS AMPLIFIED. THE LATTER IS MORE CONSISTENT WITH PREVIOUS RUNS AND IS FAVORED...BUT CONFIDENCE IS FAIRLY LOW FOR THIS TIME OF YEAR. TUESDAY STILL LOOKS DRY WITH SURFACE RIDGING EXTENDING NORTHWARD INTO THE STATE. BEYOND THAT...THERE WILL LIKELY BE 1 TO 2 DAYS WITH A CHANCE OF RAIN...BUT IDENTIFYING THOSE DAYS IS DIFFICULT DUE TO TIMING ISSUES. WILL FAVOR THE OPERATIONAL MRF FOR NOW...BRINGING THE NEXT COLD FRONT INTO THE NORTHERN LAKES LATE THURSDAY...AND WILL ADD CHANCE POPS FOR THAT DAY ONLY FOR NOW. .APX...NONE. ZOLTOWSKI
