NWS Gaylord, MI wrote its last area forecast discussion before the first event at Jul 22, 3:25 PM EST, 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 425 PM EDT SAT JUL 22 2006 .DISCUSSION...ILL DEFINED FRONT DIFFICULT TO PICK OUT ON MID AFTERNOON SFC ANALYSIS...POSSIBLY DROPPING DOWN THROUGH LOWER MICHIGAN AND EXTENDING INTO WISCONSIN. WATER VAPOR IMAGERY REVEALING MID LEVEL TROUGH AXIS SLIPPING DOWN ACROSS THE REGION WITH A VORTICITY CENTER SITTING OVER S/SE ONTARIO. SUBTLE COOLING ALOFT COMBINED WITH DAYTIME HEATING ABLE TO GENERATE SFC BASED CAPE VALUES RUNNING IN THE 500-1000 J/KG RANGE PER 3 PM LAPS ANALYSIS. DESPITE THE ILL-DEFINED BOUNDARY...AFTERNOON CONVECTION MANAGED TO KICK OFF WITHIN AREAS OF ENHANCED LOW LEVEL CONVERGENCE...PRIMARILY IN THE HIGHER TERRAIN OF NRN LOWER MI AND ALONG THE SOUTHERN SHORELINE OF EASTERN UPPER MI. TONIGHT...FORECAST CONCERNS OBVIOUSLY REVOLVE AROUND PRECIP CHANCES. AS NOTED ABOVE...ONGOING CONVECTION BY AND LARGE DRIVEN BY HEATING OF THE DAY AND AREAS OF ENHANCED LOW LEVEL CONVERGENCE. EXPECT INTENSITY AND COVERAGE TO MAX OUT IN THE NEXT HOUR OR SO FOLLOWED BY CONVECTION WANING EARLY THIS EVENING. SO...HAVE BASICALLY CARRIED SCT SHOWER AND THUNDERSTORM CHANCES WHERE COVERAGE IS GREATEST... SURROUNDED BY ISOLATED CHANCES JUST ABOUT EVERYWHERE ELSE. AS FAR AS SEVERE WEATHER IS CONCERNED...WITH FREEZING LEVELS SITTING AROUND 10K FEET CANNOT COMPLETELY RULE OUT AN ISOLATED HAILER. BUT GIVEN THE INSTABILITY IS RUNNING ON THE MARGINAL SIDE TO SUPPORT DECENT UPDRAFTS...SVR HAIL NOT LIKELY. OVERNIGHT...SHEAR AXIS FORECAST TO SLIP DOWN INTO THE AREA WITH COOLER AIR FILTERING IN (850 MB TEMPS DIPPING INTO THE +8C TO +10C RANGE). NOT ENTIRELY CERTAIN THAT OVERNIGHT HOURS REMAIN TOTALLY DRY AS THE SHEAR AXIS DROPS DOWN (NAM QPF FIELD WOULD SUGGEST AT A FEW SHOWERS AROUND). BUT AT THIS POINT HAVE KEPT THE DRY FORECAST GOING. OTHERWISE...ONCE AGAIN FACED WITH SOME LAKE CLOUD POSSIBILITIES ACROSS THE CWA PARTICULARLY IN NE LOWER MICHIGAN AS THE COOLER AIR ARRIVES AND HAVE GONE PARTLY TO MOSTLY CLOUDY. SUNDAY...MID LEVEL TROUGH AXIS BEGINS TO MOVE OFF TO THE EAST DURING THE AFTERNOON HOURS WITH SOME WARMING ALOFT AND DRYING IN THE LOWER LAYERS. NAM/GFS MODEL SOUNDINGS SHOWING A GOOD CAPPING LAYER DEVELOPING BY AFTERNOON IN MOST AREAS OF THE CWA. COMBINED WITH DRYING IN THE LOWER LAYERS...DONT THINK WE WILL SEE A REPEAT OF TODAY IN TERMS OF THE CONVECTION. THE ONE EXCEPTION...DOWN ACROSS THE S/SE PORTION OF THE CWA WHERE THE COOL AIR ALOFT AND BETTER MOISTURE LINGERS THE LONGEST....COMBINED WITH SOME ENHANCED CONVERGENCE FROM EAST FLOW OFF LAKE HURON. WITH THAT IN MIND HAVE PUT IN A CHANCE FOR SHOWERS/THUNDER IN THAT AREA DURING THE AFTERNOON. ADAM EXTENDED DISCUSSION...NAM AND GFS HAVE BEEN FAIRLY CONSISTENT AS OF THE PAST COUPLE RUNS. BOTH SHOW A PATTERN CHANGE COMING AS THE STRONG WESTERN NOAM RIDGE STARTS TO BREAK DOWN AND A MORE ZONAL FLOW REGIME TAKES HOLD OVER NORTH AMERICA. SUBTLE SHORTWAVES ROUNDING THE EASTERN NOAM TROUGH WILL KEEP THE WEATHER ACROSS MICHIGAN UNSETTLED THROUGH SUNDAY. MEANWHILE...A STRONGER SHORTWAVE WILL DIVE INTO CENTRAL ONTARIO WHICH WILL SEND A COLD FRONT OVER MICHIGAN ON MONDAY. THIS COLD FRONT IS EXPECTED TO STALL OVER CENTRAL MICHIGAN AND WILL PROVIDE THE FOCUS FOR PRECIP THROUGH AT LEAST WEDNESDAY. SUNDAY NIGHT THROUGH MONDAY...HIGH PRESSURE SUNDAY EVENING QUICKLY SLIDES EAST WHILE A STRONG SHORTWAVE DIVES ACROSS CENTRAL ONTARIO...AND ITS ASSOCIATED COLD FRONT MOVES OVER CENTRAL LAKE SUPERIOR AND THE WESTERN U.P. NAM/GFS BOTH SHOW ITS WARM FRONT PLOWING ACROSS THE CWA MONDAY MORNING...WHICH IS TRENDING A LITTLE SLOWER. 30-35KT 850MB LLJ IS TRENDING FARTHER NORTH WITH THE NOSE REACHING INTO CENTRAL ONTARIO WHERE THE BETTER UPPER LEVEL DYNAMICS ARE LOCATED WITH THE SHORTWAVE. BUT THE BEST 305K ISENTROPIC LIFT IS LOCATED ACROSS EASTERN UPPER AND HAVE BUMPED UP POPS THERE. INSTABILITY IS MEAGER AT BEST WITH 850MB CAPES NO MORE THAN 200 J/KG AND 700-500MB LAPSE RATES LESS THAN 6 C/KM. CAN SEE SHRA AND ISOLD -TSRA TO DEVELOP ALONG AND TO THE LEFT OF THE LLJ WHERE THE HIGHEST THETA-E AIR IS LOCATED...THAT THEN TRY TO PROPAGATE TO THE SE AS THEY FOLLOW THE 850-300MB THICKNESS CONTOURS. HAVE THEREFORE EXTENDED POPS TO COVER THE ENTIRE CWA TO TAKE THIS INTO ACCOUNT...BUT BELIEVE THEY WILL RUN INTO A MORE STABLE AIRMASS AND WEAKEN AS THEY GO. THEN THE COLD FRONT PUSHES SLOWLY THROUGH DURING THE AFTERNOON ON MONDAY SO WILL KEEP A CHANCE OF THUNDERSTORMS FOR THIS PERIOD. WEAK MID-LEVEL LAPSE RATES AND CLOUD COVER WILL LIMIT INSTABILITY SOMEWHAT NEEDED TO PRODUCE ANYTHING SEVERE. MONDAY NIGHT INTO TUESDAY...FRONTAL BOUNDARY STALLS OUT OVER CENTRAL MICHIGAN AS THE WESTERN RIDGE PREVENTS THIS FRONT FROM MAKING MUCH PROGRESS SOUTHWARD. THIS FRONT THEN RETURNS AS A WARM FRONT AS ANOTHER WAVE PROGRESSES INTO THE WESTERN GREAT LAKES AND SOUTHERLY LOW LEVEL FLOW STRENGTHENS. AGAIN...INSTABILITY ON TUESDAY WILL DEPEND ON CLOUD COVER...BUT WILL HAVE TO KEEP A CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH THESE PERIODS. WEDNESDAY THROUGH FRIDAY...CONFIDENCE CONTINUES TO BE LOW IN THE DAY 5-7 FORECAST AS MODELS ARE STRUGGLING BIG TIME WITH THE EVOLUTION OF THE UPPER AIR PATTERN CHANGE. IN GENERAL...A NEGATIVE PNA PATTERN IS SETTING UP ACCORDING TO THE NCEP ENSEMBLE WITH RIDGING OVER THE NORTH CENTRAL PACIFIC...TROUGHING OVER WESTERN NORTH AMERICA...AND WEAK RIDGING OVER THE CENTRAL/EASTERN US. THIS WOULD USUALLY PLACE NORTHERN MI IN A WARMER/MORE ACTIVE PATTERN...BUT STILL TOO EARLY FOR SPECIFICS. GFS IS THE OUTLIER COMPARED TO THE ECMWF/CANADIAN...AS ITS SOLUTION IS MUCH SLOWER (SEE HPC PREEPD). THEREFORE WILL LEAN ON THE ECMWF AND THE HPC SOLUTION. 500 MB TROUGH IS EXPECTED TO DIVE OVER MANITOBA AND ONTARIO...WHICH WILL SEND A COLD FRONT THROUGH THE AREA ON WEDNESDAY. THE EXTENT OF ITS SOUTHERN PROGRESSION IS IN QUESTION...WHICH WILL DETERMINE IF POPS ARE NEEDED FOR THURSDAY...BEFORE HIGH PRESSURE SETTLES IN. WITH THIS MUCH UNCERTAINTY...PREFER TO LEAVE THE GRIDS ALONE THROUGH THESE PERIODS AND NOT BOUNCE BACK AND FORTH LIKE A YOYO. MPC && .APX...WATCHES/WARNINGS/ADVISORIES...NONE. &&
