AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 248 PM EDT WED JUN 21 2006 .SHORT TERM... AFTER THE CONVECTION EXITS THE AREA THIS EVENING THERE IS SOME QUESTION OF CONVECTION HEAD OF THE CANADIAN COLD FRONT... WHICH COMES THROUGH THE GRR CWA THURSDAY NIGHT? THE OTHER ISSUE IS JUST HOW COLD WILL IT GET BEHIND THE CANADIAN COLD FRONT FOR HIGHS ON FRIDAY AND LOWS SATURDAY MORNING. THE THREAT FOR SEVERE WEATHER CONTINUES AS THERE IS STILL 2000 TO 3000 J/KG OF 100 MB MIXED LAYER CAPE OVER THE SW CWA. THERE IS ALSO AN AXIS OF 200 TO 300 J/KG OF CAPE IN THE -10 TO -30C LAYER UPSTREAM OVER WI HEADING TOWARD LOWER MICHIGAN. THAT MEANS THERE IS A SIGNIFICANT AMOUNT OF ELEVATED CAPE THAT CAN BE TAPPED YET. THE MAX MID LEVEL LAPSE RATE OF 7C IS OVER SOUTHWEST LOWER MICHIGAN AT THIS TIME. SO...UNTIL THE SECOND SHORTWAVE... SEEN ON THE WATER VAPOR LOOPS MOVING THROUGH CENTRAL IOWA AT 18Z... WE STILL HAVE A CHANCE OF SEVERE STORMS. THUS I WILL CONTINUE THE THREAT OF THUNDERSTORMS ACROSS THE CWA INTO THE EARLY EVENING. TONIGHT...THE IOWA SHORTWAVE COMPLEX WILL BE THROUGH THE CWA BY EARLY THIS EVENING. THAT SHOULD CLEAR OUT THE CONVECTION FROM NORTH TO SOUTH DURING THE MID EVENING. SINCE THE PRIMARY COLD FRONT DOES NOT GET INTO THE SOUTHERN SECTIONS OF SOUTHWEST LOWER MICHIGAN UNTIL THURSDAY DURING THE MID DAY HOURS... SOME CONVECTION COULD LINGER OVER THE SOUTHERN CWA TILL WELL AFTER MIDNIGHT. ELSEWHERE THE CONVECTION SHOULD END BEFORE 10 PM. THURSDAY...ANOTHER PACIFIC SHORTWAVE HEADS EAST ON THE ZONAL FLOW OF THE SOUTHERN STREAM POLAR JET. MEANWHILE A DIGGING WAVE ROTATING AROUND THE HUDSON BAY POLAR VORTEX PULLS A STRONG...FOR THIS TIME OF YEAR...COLD FRONT SOUTH INTO THE GREAT LAKES DURING THE DAY. SOUTHWEST LOWER MICHIGAN IS IN THE ENTRANCE REGION OF SOUTHERN STREAM JET SPEED MAX DURING THE AFTERNOON TOO. GIVEN THE LACK OF MID LEVEL MOISTURE...THIS IS A QUESTIONABLE EVENT AT BEST. ALL OF THIS WILL ACT TOGETHER TO ALLOW A LEAST A SLIGHT CHANCE OF THUNDERSTORMS THURSDAY. IT SHOULD BE WARMER THAN TODAY SINCE THERE WILL BE MORE SUNSHINE. THURSDAY NIGHT THROUGH FRIDAY NIGHT...THE COLD FRONT COMES THROUGH BUT THERE IS STILL THE ISSUE OF THE ENTRANCE REGION OF THE SOUTHERN STREAM JET OVER THE GREAT LAKES. THAT IS AIDED BY THE CONFLUENCE OF THE NORTHERN AND SOUTHERN STREAM JETS OVER THE GREAT LAKES. THAT JET ENTRANCE REGION WILL ALLOW FOR SOME MID LEVEL MOISTURE TO BE PULLED NORTH AND KEEP THE SKY FROM CLEARING TILL FRIDAY NIGHT. FRIDAY NIGHT COULD BE VERY CHILLY OF THE WAF-NAM IS CORRECT WITH THE 1000/925 THICKNESS AND HOW MUCH OF THAT CANADIAN COLD AIR GETS THIS FAR SOUTH. LOW WILL BE WELL DOWN INTO THE 40S ACROSS THE AREA. .LONG TERM... LITTLE CHANGE IN THE EXTENDED NEEDED. SURFACE HIGH PRESSURE WILL DOMINATE THE CONDITIONS THROUGH THE WEEKEND INTO EARLY NEXT WEEK. GIVEN THE DRY LOW LEVELS AND SUBSIDENCE UNDER THE HIGH WILL STAY WITH A DRY FORECAST SATURDAY THROUGH TUESDAY. THE NEXT CHC FOR PCPN SHOULD COME ABOUT TUESDAY NIGHT INTO WEDNESDAY AS A SHORT WAVE AND ASSOCIATED COLD FRONT MOVES INTO THE WESTERN GREAT LAKES. WILL INTRODUCE CHC POPS ACROSS THE NORTHERN HALF TUESDAY NIGHT AND SPREAD THE CHCS ACROSS THE CWA ON WEDNESDAY. .GRR WATCHES/WARNINGS/ADVISORIES...NONE. && WDM JK
