AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 221 AM EDT MON JUL 22 2002 THE LATEST SFC ANALYSIS SHOWS A COLD FRONT EXTENDING FROM NW LWR SOUTHWEST INTO ERN WI AND NRN IA. A PREFRONTAL TROUGH EXTENDED FROM NORTH CENTRAL LWR SOUTHWEST THRU SRN LAKE MICHIGAN. ABUNDANT MID LVL BKN CLOUDINESS WAS NOTED ALONG THE ENTIRE FRONTAL BOUNDARY WITH A MIX OF CU AND CI COVERING THE CWA. SFC WINDS WERE GENERALLY FROM A WESTERLY DIRECTION WEST OF THE PREFRONTAL TROUGH. AHEAD OF THE TROUGH TEMPS WERE IN THE LOWER 90S AND DWPTS IN THE LOWER 70S WITH CAPES AROUND 3K J/KG AND LIS OF -4 TO -7. CONCERNS WITH THIS PACKAGE MAINLY DEAL WITH CONVECTIVE CHANCES TONIGHT. 12Z SHORT RANGE MODELS WERE IN GOOD AGREEMENT WITH RESPECT TO UPR LVL SOLUTIONS. A BASIC ZONAL FLOW WILL EXTIST ACROSS THE CWA THRU WED NIGHT WITH UPR HIGH PRESSURE OVER BERMUDA AND THE 4 CORNERS REGION. THINK THE BEST CHANCE OF STORMS IS ALONG AND JUST AHEAD OF THE TROUGH THIS EVENING. THE MODELS PROG THIS TROUGH THRU THE CWA EARLY THIS EVENING. AS THIS PASSES, TSRA CHANCES WILL DIMINISH CONSIDERABLY. WILL KEEP LOW CHC POPS GOING TONIGHT AHEAD OF THE ACTUAL FRONT WHICH THE MESOETA PROGS THRU AROUND 09Z. WILL GO WITH AN OVERALL PT CLDY SKY. ON TUESDAY HIGH PRESSURE WILL SLIDE EAST FROM THE NRN PLAINS TO THE NRN LAKES. IN THE ABSENCE OF ANY SHORT WAVES MOVING THRU THE WESTERLIES, THE HIGH AND THE DRY AIR ASSOCIATED WITH IT WILL GENERATE QUITE A BIT OF SUNSHINE AS FCST SOUNDINGS SHOW DRY PROFILES. HUMIDITY WILL BE MUCH LOWER THAN THE PAST SEVERAL DAYS AS DWPTS DROP INTO THE MID 50S. CU ROUTINE SHOWS THE POTENTIAL FOR SCT CU ON TUESDAY AND WEDNESDAY BUT LIMITED AMOUNTS OF MOISTURE SHOULD PRECLUDE ANYTHING MORE. MOS TEMPS LOOK REASONABLE. 93 EXTENDED FORECAST THE CANADIAN MODEL HAS TRENDED TOWARD A STRONGER RETURN FLOW OF MOISTURE ON THURSDAY....SUGGESTING THE POTENTIAL FOR SOME PRECIPITATION. OTHER MODELS INDICATE OTHERWISE. CONSIDERING THE FLOW WILL BE PRIMARILY EAST TO SOUTHEAST...WHICH IS TYPICALLY A DRY FLOW...WILL CONTINUE TO FEATURE A DRY FORECAST FOR THURSDAY.
