AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 325 PM EDT THU AUG 7 2003 .SHORT TERM...WATER VAPOR IMAGERY REVEALING MID LEVEL TROUGH OVER THE EASTERN CONUS WITH THE MAIN TROUGH AXIS EAST OF THE STATE. WEAK IMPULSES CONTINUE TO SLIP THROUGH THE NORTHERLY FLOW HELPING TO TOUCH OFF/ENHANCE PRECIP WITH DIRUNAL HEATING. ONE IMPULSE MAKING ITS WAY SOUTHWARD ACROSS CENTRAL LOWER MI...WHILE SECOND SLOW MOVING FEATURE NOW DROPPING SOUTH ACROSS EASTERN UPPER MICHIGAN. MAIN FORECAST ISSUES IN SHORT TERM CONTINUE TO BE WITH DIRUNAL SHOWERS AND THUNDERSTORMS LATE THIS AFTERNOON AND EARLY THIS EVENING. KAPX RADAR SHOWING TWO SEPARATE PRECIP REGIMES OVER THE CWA CURRENTLY. AREA OF SHOWERS/THUNDERSTORMS IN EAST UPPER MI ASSOCIATED WITH SLOW MOVING IMPULSE DROPPING SOUTHWARD AND AIDED BY AFTERNOON HEATING...WHILE VERY CELLULAR (ALL DIURNALLY DRIVEN) LOOKING SHOWERS NOW ACROSS A GOOD PORTION OF NORTHERN LOWER MI AWAY FROM MARINE INFLUENCES. TONIGHT...SHOWERS/THUNDERSTORMS WILL CONTINUE TO IMPACT A GOOD PORTION OF THE CWA INTO THE EARLY EVENING HOURS...PRIMARILY AWAY FROM MARINE INFLUENCES AND ESPECIALLY AHEAD OF WEAK IMPULSE DROPPING SOUTH THROUGH THE AREA. THUS...WILL CONTINUE WITH SCATTERED POPS THROUGH THIS EVENING WITH THE BEST POPS IN THE CENTRAL AND EASTERN HALF OF THE CWA AND ACROSS EASTERN UPPER MICHIGAN. THEN...DIURNAL CLOUD COVER WILL DISSIPATE QUICKLY BY LATE EVENING BUT CONCERNED THAT STRATUS MAY AGAIN FORM OVER THE CWA LATE. HOWEVER...MODEL SOUNDINGS NOT NEARLY AS SATURATED IN THE LOWEST LAYERS AND IN THE ABSENCE OF ANY SYNOPTIC FEATURE MOVING THROUGH (AFTER 06Z OR SO) STRATUS MAY NOT BE A BIG AN ISSUE AND WILL GO WITH PARTLY CLOUDY SKIES OVER THE AREA. .LONG TERM...FORECAST CONCERNS FRIDAY THROUGH SUNDAY FOCUS ON POPS AND CLOUD COVER. SKIES MAY TURN OUT MOSTLY SUNNY DUE TO STABLE MARINE LAYER OVER/NEAR LAKE MICHIGAN FRIDAY. OTHERWISE...EXPECT SUFFICIENT LOW TO MID LEVEL MOISTURE TO LIMIT SUNSHINE MOST AREAS FRIDAY. 12Z MODELS DEPICT A SUBTLE EASTWARD SHIFT IN THE UPPER TROUGH AXIS FRIDAY. HOWEVER...ANOTHER SHORTWAVE IS FORECAST TO ROUND PARENT CIRCULATION CENTER...DROPPING INTO N/E COUNTIES OF THE FORECAST AREA FRIDAY AFTERNOON/EVENING AND ENHANCING ANOTHER ROUND OF DIURNAL CONVECTION. WILL CONTINUE A DRY FORECAST IN THE EXTREME SW (S OF TVC AND W OF CAD)...AND WILL ONLY MENTION SHOWERS NEAR WHITEFISH BAY... WEST OF TROF AXIS/WHERE STABLE MARINE LAYER WILL LIMIT CONVECTIVE POTENTIAL. FOR ALL OTHER AREAS...WILL CARRY CHANCE POPS FRIDAY AFTERNOON/EVENING. THEN...STRATUS/PATCHY FOG WILL AGAIN DEVELOP OVERNIGHT FRIDAY INTO EARLY SATURDAY MORNING. SATURDAY...UPPER TROUGH MAY UNDERGO A MORE SIGNIFICANT SHIFT TOWARD THE EAST...WITH THE POTENTIAL FOR SHORTWAVE RIDGING (AHEAD OF APPROACHING SHORTWAVE)/INCREASINGLY ANTICYCLONIC SURFACE FLOW...ESPECIALLY ACROSS THE WEST. THUS...WILL CARRY NO POPS ALONG AND WEST OF AN ANJ-GLR-HTL LINE...AND WILL LIMIT PM POPS TO 20% (NO THUNDERSTORM WORDING IN ZFP) FARTHER EAST. MEANWHILE...FORECAST WILL ALLOW FOR PARTLY SUNNY SKIES SATURDAY. HOWEVER...LOW CLOUDS MAY BECOME TRAPPED UNDER SUBSIDENCE INVERSION...RESULTING IN MOSTLY CLOUDY SKIES IN SOME AREAS. SUNDAY...12Z GFS/ETA DEPICT A SHORTWAVE DROPPING INTO THE REGION FROM THE NW. THIS FEATURE WILL ONCE AGAIN STRENGTHEN THE LONGWAVE UPPER TROUGH OVER THE REGION...JUSTIFYING CHANCE PM POPS IN ALL AREAS. LATEST MEDIUM RANGE MODELS SUGGEST UPPER TROUGH WILL LINGER INTO AT LEAST NEXT TUESDAY...WITH A TRANSITION TO UPPER RIDGING IN THE TUESDAY/WEDNESDAY TIME FRAME. THIS SCENARIO JUSTIFIES CHANCE POPS ALL AREAS MONDAY AND SOUTH OF THE STRAITS TUESDAY (UPPER RIDGE SHOULD START TO BUILD INTO UPPER MICHIGAN TUESDAY). THEN...EXPANDING RIDGE SHOULD PROVIDE A DRY DAY ACROSS THE FORECAST AREA WEDNESDAY. THEN...0Z OPERATIONAL GFS PUSHES A COLD FRONT QUICKLY INTO THE REGION FROM THE NW THURSDAY. HOWEVER...GIVEN GRADUAL EVOLUTION OF PATTERN AND SW-NE ORIENTATION OF RIDGE AXIS THAT WILL EVENTUALLY BUILD INTO THE REGION...0Z GFS SOLUTION APPEARS TO BE BREAKING DOWN THE UPPER RIDGE TOO QUICKLY (AS OPPOSED TO YESTERDAYS 12Z EUROPEAN WHICH MAINTAINS A SHARP RIDGE OVER REGION)...SO WILL OPT FOR A DELAYED FROPA/DRY FORECAST THURSDAY. .APX...NONE.
