AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 345 AM EDT FRI MAY 13 2005 .SHORT TERM... OUR PRIMARY SHORT TERM FCST CONCERN REVOLVES AROUND ASSESSMENT OF TODAYS SVR WX THREAT WHICH CERTAINLY STILL EXISTS. SEVERAL FACTORS HAVE INCREASED TODAYS SVR WX THREAT. ONE IS THE DELAY IN PCPN GETTING INTO OUR AREA. WE WERE CONCERNED THAT ABUNDANT CLOUD COVER AND PCPN IN THE MORNING WOULD MITIGATE THE SVR WX THREAT SOMEWHAT. HOWEVER NOW IT APPEARS WE WONT BE IN A STEADY RAIN SITUATION THIS MORNING AND IN FACT MANY LOCATIONS ACROSS OUR CENTRAL AND EASTERN CWA WILL PROBABLY BE DRY MOST OR ALL OF THIS MORNING WHICH WILL PROMOTE DEVELOPMENT OF GREATER INSTABILITY. FURTHERMORE, LATEST GUIDANCE SUGGESTS OUR SOUTHERN CWA WILL ALSO STAY MAINLY DRY THROUGH EARLY THIS AFTERNOON. THAT COMBINED WITH A FURTHER NW SFC LOW TRACK SUGGESTS STRONGLY THAT SFC TEMPS SOUTH WILL INDEED REACH THE LOWER AND PERHAPS EVEN MIDDLE 70S. IN FACT QUITE A BIT OF CLEARING IS NOTED SOUTH IN INDIANA AND AS THE WARM FRONT SURGES NORTH OUR SOUTHERN CWA IN PARTICULAR COULD VERY WELL GET SOME SUN TODAY. AS A RESULT OF STRONG SFC HEATING, THE SB CAPE IN JXN IS PROGGED TO REACH AROUND 1500 J/KG BY MID TO LATE AFTERNOON AND THE ETA HAS TRENDED UP WITH CAPE VALUES OVER OUR SOUTH THE PAST COUPLE RUNS. THIS TYPE OF CAPE IN CONJUNCTION WITH 0-1 KM SRH VALUES OF 150-175 M2/S2 WHICH REPRESENTS A LITTLE OVER 50% OF THE 0-3 KM SRH OF AROUND 300 M2/S2 CERTAINLY IMPLIES THE POTENTIAL FOR ISOLATED TORNADOES. ALSO IN FAVOR OF THE POTENTIAL FOR SUPERCELLS ARE 0-6 KM BULK SHEAR VALUES OF 40 TO AS HIGH AS 65. OTHER CONVECTIVE INDICES ESPECIALLY SOUTH ARE VERY IMPRESSIVE INCLUDING LIS OF -3 TO -4... TOTAL TOTALS IN THE LOWER 50S AND K INDICES IN THE MID 30S BY MID AFTN. EHIS ARE ALSO PROGGED TO BE VERY IMPRESSIVE ALONG THE I-94 CORRIDOR (1 TO AS HIGH AS 3 MID TO LATE AFTN). THERE ARE A FEW FACTORS GOING AGAINST SVR WX INCLUDING THE FACT THAT THE SFC LOW ITSELF ISNT IMPRESSIVE. THE H5 TROF AXIS REMAINS WELL TO OUR WEST THIS AFTERNOON THOUGH WE SHOULD GET SOME MODEST PVA. FINALLY THE CORE OF STRONGER WINDS ALOFT REMAINS SITUATED TO OUR WEST THIS AFTERNOON. NONE OF THIS MAY MATTER THAT MUCH THOUGH IF LINE AND BOW SEGMENTS DEVELOP IN THE HIGH INSTABILITY AXIS THIS AFTERNOON OUT AHEAD OF THE COLD FRONT NEAR THE WARM FRONT AND IN THE WARM SECTOR. BOTTOM LINE... WE CERTAINLY HAVE POTENTIAL FOR A DECENT SVR WX EVENT TODAY, THOUGH IT IS BY NO MEANS A SLAM DUNK THIS TIME AROUND. DAMAGING WIND GUSTS IN ASSOCIATION WITH BOWING SEGMENTS AND LARGE HAIL (NOTE MID LEVEL DRY PUNCH) WILL BE PRIMARY THREATS TODAY. NUMEROUS DAMAGING WIND GUST AND LARGE HAIL REPORTS WERE NOTED YESTERDAY ACROSS KANSAS AND NORTHERN MISSOURI. AN ISOLATED TORNADO OR TWO CERTAINLY CANNOT BE RULED OUT ANYWHERE IN THE VICINITY OF THE WARM FRONT... ANY RESIDUAL BOUNDARIES FROM MORNING CONVECTION WHERE LOW LEVEL WIND FIELDS HAVE BEEN ALTERED... AND SOUTH IN THE WARM SECTOR. OUR SOUTH/SE CWA WOULD PROBABLY BE MOST FAVORED FOR AN ISOLATED TORNADO WHERE GREATEST SFC BASED INSTABILITY WILL BE GENERATED COINCIDENT WITH HIGH SRH VALUES BY THIS AFTERNOON. THE DAY SHIFT WILL NEED TO MONITOR THIS SITUATION VERY CLOSELY AND WE WILL NEED TO BE VERY DILIGENT ABOUT MESOANALYSIS. ALL STORMS WILL BE CAPABLE OF PRODUCING VERY HEAVY RAIN AS WELL DUE TO THE RAPID INFLUX OF LOW LEVEL MOISTURE AS PW VALUES CLIMB TO AROUND 1.5. ANOTHER KEY TO THE FCST WILL BE HOW MUCH PCPN THIS MORNING WORKS THE ATMOSPHERE OVER. WE HAVE PCPN TIMED TO MOVE INTO OUR FAR WESTERN CWA AROUND 12Z AND CONTINUE TO MOVE NE. THIS MAY WORK THE ATMOSPHERE OVER SOMEWHAT OUR WESTERN CWA THOUGH A RECOVERY TO MORE UNSTABLE CONDITIONS THIS AFTERNOON IS POSSIBLE. IT IS VERY POSSIBLE OUR EASTERN CWA MAY REMAIN DRY THROUGH THE MORNING. THE REST OF THE FCST IS TRICKY TOO. DUE TO MODEL TRENDS BEING A LITTLE SLOWER WITH THIS SYSTEM IT APPEARS THUNDERSTORMS WILL LINGER INTO THIS EVENING (MAINLY SE) BEFORE GRADUALLY TAPERING OFF TO JUST SCATTERED SHOWERS OVERNIGHT AS THE LOW MOVES EAST OF OUR AREA. SATURDAYS FCST IS TRICKY TOO SINCE THERE ARE INDICATIONS THAT A SECONDARY (AND PERHAPS QUITE FORMIDABLE ACCORDING TO THE GFS) LOW PRESSURE WAVE WILL TRACK NE AND BRING US MORE SHOWERS AND TSTORMS SATURDAY. WELL HAVE A LOT OF CLOUD COVER AND SCATTERED INSTABILITY RAIN SHOWERS SATURDAY NIGHT AS THE H5 TROF AXIS AND COLD POOL OF AIR ALOFT MOVE DIRECTLY OVER OUR AREA. SUNDAY CONTINUES TO LOOK VERY COOL WITH BRISK WNW FLOW AND SCATTERED INSTABILITY RAIN SHOWERS STILL AROUND WITH THE UPPER TROF AXIS STILL OVER OUR AREA. .LONG TERM... MADE VERY FEW CHANGES IN THE EXTENDED PERIOD OF SUNDAY NIGHT THROUGH THURSDAY. GOING FORECAST WAS IN GOOD SHAPE. UPPER TROUGH WILL STILL BE OVERHEAD SUNDAY NIGHT...BUT IT WILL BE MOVING EAST AND DRIER AIR WILL BE ADVECTING INTO THE FORECAST AREA. KEPT SUNDAY NIGHT DRY...ENVISIONING DECREASING CLOUDS FROM WEST TO EAST OVERNIGHT. MONDAY THROUGH TUESDAY LOOK TO BE DRY WITH SURFACE RIDGING DRIFTING THROUGH THE GREAT LAKES. GFS GUIDANCE HIGHS WERE COOLED A BIT FOR MONDAY AND TUESDAY IN THE LATEST RUN AND THIS SEEMS REASONABLE AS THERE IS NOT A STRONG SOUTHERLY GRADIENT EITHER DAY. HIGHS BOTH DAYS SHOULD MAINLY BE IN THE 60S. TUESDAY NIGHT...WEDNESDAY AND WEDNESDAY NIGHT CONTINUED THE MENTION OF SHOWERS AND THUNDERSTORMS AS SOUTHERLY FLOW TAKES HOLD AS A FRONTAL SYSTEM TRIES TO MOVE THROUGH THE AREA. HIGHS WEDNESDAY WILL BE TEMPERED BY THE CLOUDS AND RAIN. LEFT THURSDAY DRY FOR NOW...BUT IT APPEARS IF MODEL TRENDS CONTINUE THAT WE MAY HAVE TO ADD A CHANCE OF RAIN TO THURSDAY TOO. EXTENDED PERIOD ON THE WHOLE WILL BE WARMER THAN THE CHILLY WEEKEND AHEAD AS THE FLOW BECOMES MORE ZONAL. TEMPERATURES THOUGH ARE EXPECTED TO BE NEAR OR EVEN SLIGHTLY BELOW NORMAL. && .GRR WATCHES/WARNINGS/ADVISORIES...NONE. && LAURENS DUKE
