AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 230 PM EDT THU MAY 25 2006 .SHORT TERM... THE MAIN CHALLENGE OVER THE SHORT TERM DEALS WITH THE POTENTIAL FOR SEVERE WEATHER THIS EVENING. LOOKS LIKE A DECENT SETUP WITH 50 KNOTS AT 10K FEET GRR VWP. ALSO SOME FAVORABLE DEEP LAYER SHEAR AND TURNING OF THE HODOGRAPH. LIFTED INDEX VALUES DOWN TO -4 TO -6 OFF OF LAPS. STRONGER SUNSHINE HAS DEVELOPED OVER EASTERN COUNTIES...WHERE THE BEST DESTABILIZATION WILL OCCUR FOR THE REST OF THE AFTERNOON. LITTLE NO CAP LEFT...SO CONVECTION SHOULD BECOME MORE WIDESPREAD THROUGH 4 PM. I WILL FEATURE CATEGORICAL RAINFALL FOR SOUTHEAST COUNTIES WHERE THE COMBINATION OF DEEP MOISTURE...FAVORABLE INSTABILITY AND PROXIMITY TO THE MID LEVEL JET SHOULD ALLOW FOR WIDESPREAD THUNDERSTORMS. AS WE STABILIZE THROUGH AFTER MIDNIGHT AND THE COLD FRONT ADVANCES EAST OF THE FORECAST AREA...THE PRECIPITATION SHOULD WIND DOWN. WILL FEATURE ONLY CHANCE OF PRECIPITATION FOR AFTER MIDNIGHT. I DID RAISE TEMPERATURES SLIGHTLY...WITH DEWPOINTS SO HIGH ACROSS THE REGION. ALSO ADDED SOME FOG GIVEN THE ABUNDANT LOW LEVEL MOISTURE. ON FRIDAY...THE GFS SHOWS LITTLE OR NO INSTABILITY...THUS WILL KEEP THE WORDING AS SHOWERS. WILL KEEP THE PRECIPITATION PROBABILITIES AT CHANCE. THE UPPER LOW IS PULLING AWAY FOR FRIDAY NIGHT AND SATURDAY...THUS DRY WEATHER IS FORECASTED. .LONG TERM... A LARGE UPPER RIDGE OVER THE REGION EARLY THIS WEEKEND WILL TRANSITION TO BROAD SOUTHWEST FLOW BY THE MIDDLE OF NEXT WEEK. WE/LL CONTINUE TO SEE ABOVE NORMAL TEMPERATURES EARLY IN THE PERIOD AND THEN A SLIGHT COOLING TREND TOWARD THE END OF NEXT WEEK AS HEIGHTS FALL AND THE RIDGE DEAMPLIFIES. WE/LL BE LOOKING AT BASICALLY DRY CONDITIONS THROUGH MONDAY NIGHT AS FORCING MECHANISIMS WILL REMAIN WEST OF THE AREA. THAT SAID...INSTABILITY WILL BE MODERATE TO HIGH DURING THE AFTERNOONS WITH LI/S NEAR -6C AND CAPE IN EXCESS OF 1K J/KG. SO ISOLD TSRA CAN/T BE RULED OUT. WE/LL MENTION PCPN AGAIN BEGINNING TUESDAY AS A WEAK FRONTAL BOUNDARY MOVES EAST TOWARD THE GREAT LAKES IN RESPONSE TO THE DEAMPLIFYING RIDGE. WE/LL END THE PCPN WED NIGHT WITH THE THOUGHT THAT THE BOUNDARY WILL BE SOUTH OF THE CWA. && .GRR WATCHES/WARNINGS/ADVISORIES...NONE. && MJS 93
