AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI ISSUED BY NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 430 PM EDT TUE MAR 27 2007 .SHORT TERM...TONIGHT AND TOMORROW MAIN FORECASTING CONCERN DEALS WITH CONVECTION CHANCES THIS EVENING AND INTO TONIGHT. A LARGE POSITIVELY TILTED UPPER LEVEL LOW CURRENTLY LOCATED OVER EASTERN OKLAHOMA CONTINUES TO LIFT SLOWLY TO THE NORTHEAST. LEAD/SHEARED ABSOLUTE VORTICITY WAVES ALSO CONTINUE TO SPIRAL OUT AHEAD OF THE PARENT VORTEX. AN AFOREMENTIONED LOBE (DCVA) HAS INTERACTED WITH PERSISTENT SURFACE TROUGH ACROSS SOUTHERN LOWER MICHIGAN AND HAS BEEN MAIN SYNOPTIC FORCING FOR CONVECTION AND THUNDERSTORMS THIS AFTERNOON. ADDITIONAL FORCING FOR THUNDERSTORMS HAS BEEN THE RIGHT ENTRANCE REGION OF +60KT JET STREAK...ALLOWING FOR ADEQUATE UPPER LEVEL DIVERGENCE. THE ATMOSPHERE AHEAD/SOUTH OF THIS SURFACE TROUGH HAD PLENTY OF MORNING SUNSHINE ALLOWING FOR MODERATE INSTABILITY...CHARACTERIZED BY SBCAPES GREATER THAN 2000 J/KG...AND SURFACE BASED LIFTED INDICES OF LESS THAN -2C. THE WIND PROFILES THIS AFTERNOON ARE RELATIVELY WEAK AND WILL LIMIT THE OVERALL WIND THREAT WITH THESE STORMS. THE PRIMARY RISK WITH THESE STORMS WILL CONTINUE TO BE LARGE HAIL OF UP TO 1 INCH AND TORRENTIAL RAINFALL. PRECIPITABLE WATER VALUES ARE APPROXIMATELY 1.2 INCHES WHICH FOR LATE MARCH RUN MORE THAN 2 STANDARD DEVIATIONS ABOVE NORMAL. SURFACE TROUGH HAS BEEN A SLOW MOVER TO THIS POINT. THINKING THIS TREND WILL CONTINUE UNTIL UPPER LEVEL JET STREAK AND INCREASING SURFACE PRESSURE NUDGES THE FRONT THROUGH. COVERAGE OF THUNDERSTORMS WILL BE NUMEROUS INTO THE OVERNIGHT SOUTH OF A DETROIT TO GRAND RAPIDS LINE. EXPECTING INTENSITY TO WANE THIS EVENING AS WE LOSE DAYTIME HEATING. SURFACE HIGH PRESSURE IN EASTERN ONTARIO WILL GAIN A FOOTHOLD ON LOWER MICHIGAN INTO THE DAY TOMORROW. PRECIPITATION CHANCE WILL BE LIMITED TO SHOWER ACTIVITY AS AFOREMENTIONED FRONT WILL HAVE CLEARED INTO NORTHERN OHIO/INDIANA AND WILL RESULT IN LIMITED INSTABILITY. THE BEST CHANCE OF PRECIPITATION CONTINUES TO BE EXTREME SOUTHWESTERN LOWER MICHIGAN AND BAROCLINIC ZONE BUBBLES UP IN RESPONSE TO LIFTING UPPER LEVEL WAVE. WITH COLD EASTERLY FLOW OFF OF LAKE HURON...AND RESIDUAL SURFACE MOISTURE AREAS OF ADVECTION FOG WILL CONTINUE THIS EVENING AND OVERNIGHT FOR AREAS ADJACENT TO LAKE HURON. && .LONG TERM...WEDNESDAY NIGHT THROUGH NEXT TUESDAY THE CENTRAL PLAINS SHORT WAVE WILL CONTINUE TO SHEAR APART AND WEAKEN IN FAVOR OF THE LARGER SCALE FEATURES IN THE UPPER FLOW WEDNESDAY NIGHT THROUGH THURSDAY. THE SHARPENING UPPER LEVEL RIDGE OVER LOWER MICHIGAN WILL REINFORCE THE STRENGTH OF THE SURFACE HIGH CENTERED OVER ONTARIO. THIS RIDGE THROUGH THE DEPTH OF THE ATMOSPHERE WILL RESULT IN LESS CLOUD COVER, COOLER TEMPS, AND STRONGER EASTERLY WINDS THROUGH FRIDAY. THE LARGE UPPER LOW LIFTING THROUGH THE PLAINS ON FRIDAY WILL BE THE MAIN CONCERN FOR OUR WEATHER THIS WEEKEND. TRENDS IN THE 12Z GFS AND NAM SOLUTIONS ARE TO CONSOLIDATE THE ENERGY IN THE UPPER LOW WITH SLOWER TIMING ON ITS MOVEMENT TOWARD THE GREAT LAKES. THIS IS IN THE DIRECTION OF THE CANADIAN AND EURO SOLUTIONS FROM RECENT DAYS AND ADDS CONFIDENCE TO THE FORECAST TIMING FOR THIS WEEKEND. ADJUSTMENTS TO THIS FORECAST PACKAGE INCLUDED ABOUT A 12 HOUR DELAY IN TIMING OF HIGHER RAIN CHANCES FRIDAY NIGHT AND SATURDAY ALONG WITH SLIGHTLY COOLER TEMPERATURES. && .AVIATION... A SURFACE TROUGH OF LOW PRESSURE WILL CONTINUE THE SLOW PROGRESSION SOUTHWARD THIS AFTERNOON. CURRENTLY THE TROUGH AXIS IS POSITIONED THROUGH LAPEER...GENESEE...SHIAWASSEE...MACOMB COUNTIES IN EASTERN LOWER MICHIGAN WHILE THE WESTWARD EXTENSION IS LOCATED OVER OCEANA...NEWAYGO...AND MONTCALM COUNTIES. SURFACE TEMPERATURES ARE AGAIN WELL ABOVE NORMAL SOUTH OF THIS TROUGH AND HAVE AIDED IN DEVELOPING A MODERATELY UNSTABLE AIRMASS. THUNDERSTORM ACTIVITY HAS BEEN LIMITED TO WESTERN LOWER MICHIGAN BUT RECENT DEVELOPMENT HAS TAKEN PLACE IN MACOMB COUNTY. EXPECTING DEVELOPMENT TO FILL IN ALONG THIS SURFACE FEATURE THIS AFTERNOON WITH ADDED SOLAR INSOLATION/HEATING. CHANCES OF THUNDERSTORMS WILL INCREASE FROM NORTH TO SOUTH AS THE SURFACE ENHANCED SURFACE CONVERGENCE ALONG THE COOL FRONT SINKS SOUTH. THUNDERSTORM ACTIVITY WILL WANE THIS EVENING AS UPPER LEVEL FORCING PULLS OFF TO THE EAST AND SURFACE HIGH PRESSURE BUILDS IN FROM ONTARIO. && .GRR WATCHES/WARNINGS/ADVISORIES...NONE. && CB/BT
