NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Aug 4, 1:46 AM EST, 3 hours 11 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 246 AM EDT THU AUG 4 2005 .SHORT TERM... SKIES ARE PARTLY/MOSTLY CLOUDY ACROSS THE CWA. KGRR-88D SHOWS SCATTERED SHOWERS WITH ISOLATED THUNDERSTORMS MOVING ACROSS THE LAKE. SFC ANALYSIS SHOWS A COLD FRONT STRETCHING FROM WESTERN LAKE SUPERIOR SOUTHWEST THROUGH NORTHWEST IOWA. FORECAST CONCERNS IN THE SHORT TERM DEAL WITH PRECIPITATION CHANCES TODAY AS THE FRONTAL BOUNDARY MOVES THROUGH. THE GFS CONTINUES TO BE A BIT SLOWER THAN THE ETA MOVING THE FRONT THROUGH. GIVEN THE AMOUNT OF HEAT AHEAD OF THE FRONT AND THAT THE UPPER JET IS MORE PARALLEL TO THE FRONT RATHER THAN NORMAL TO IT SUGGESTS THAT ITS MOVEMENT WILL BE ANYTHING BUT QUICK. REFLECTIVITIES ARE INCREASING ON THE RADAR ATTM DUE TO AN INCREASE IN THETA-E ADVECTION AND THE LLJ MOVING INTO THE REGION. A QUICK LOOK AT 00Z RAOBS SHOWS WHY A LOT OF IT ISNT REACHING THE GROUND....THE COLUMN IS PRETTY DRY FROM 650-800 MB. THAT WILL CHANGE TODAY AS MOISTURE CONTINUES TO ADVECT IN. CONVECTION ONGOING TO THE WEST ALONG THE WESTERN PORTION OF THE FRONTAL BOUNDARY WILL ARRIVE THIS AFTERNOON AS THE FRONT MOVES INTO THE CWA. THE AIR WILL BE PRETTY JUICY TODAY WITH LIS BELOW 0C AND CAPE ABOVE 1K J/KG IF WE CAN DESTABILIZE...WHICH IS IN QUESTION. 0-6KM SHEAR ISNT ALL THAT IMPRESSIVE...BELOW 25KTS. THIS MORNINGS CONVECTION MAY PRODUCE QUITE A BIT OF CLOUDINESS TODAY WHICH WOULD LIMIT THE DEGREE OF INSTABILITY THIS AFTERNOON. COUPLED WITH THE LESS THAN IMPRESSIVE SHEAR VALUES, THE OVERALL THE SEVERE THREAT APPEARS MINIMAL. THE FRONT WILL CLEAR THE CWA THIS EVENING. THE TRAILING UPPER TROUGH WILL TAKE UNTIL LATE TONIGHT TO MOVE THROUGH. I SUSPECT WELL SEE QUITE A BIT OF CLOUDINESS THIS EVENING AND DURING THE EARLY OVERNIGHT HOURS WITH CLEARING AFTER 06Z ACROSS THE NORTHWEST CWA. THE UPPER FLOW WILL BECOME MORE ZONAL ON FRIDAY AND CONTINUE THROUGH SATURDAY WHILE SFC HIGH PRESSURE BUILDS IN FROM THE WEST. 1000-500 MB THICKNESS VALUES FALL TO 564 DM BY 12S SATURDAY SUGGESTING A BRIEF REPRISE OF THE COOL WX WE SAW LAST WEEK. IT WONT LAST LONG THOUGH AS THE HIGH WILL MOVE EAST BY LATE SATURDAY AND WINDS WILL AGAIN VEER TO THE SOUTHWEST. .LONG TERM... THE EXTENDED PERIOD BEGINS ON SUNDAY WITH SFC RIDGING HOLDING ON BUT RETURN FLOW UNDERWAY BY MONDAY. MOISTURE POOLING AHEAD OF A COLD FRONT BY TUESDAY COULD BRING THE CHANCE OF SHOWERS...BUT LOCATION AND TIMING OF THE FRONT INTO SOUTHWEST LOWER MICHIGAN IS THE SUBJECT OF MODEL DIFFERENCES IN THE TUESDAY-THU PERIOD. CURRENT FORECAST HAS POPS FOR TUESDAY ON...AND IT SEEMS REASONABLE TO KEEP THEM AS SFC FRONT AND UPPER FLOW ARE NEARLY PARALLEL...RESULTING IN THE POSSIBILITY OF THE FRONT REMAINING ACROSS THE AREA FOR A WHILE. .GRR WATCHES/WARNINGS/ADVISORIES...NONE. && 93 OSTUNO
