THE FLT ORIGINATED AT 0151 CDT AFTER THE PLT & PSGR HAD SPENT A DAY SIGHTSEEING & ATTENDED A NGT BASEBALL GAME. BEFORE DEPG, THE PLT RCVD A WX BRIEFING & FILED AN IFR FLT PLAN. OVC SKIES WITH CUMULIFORM CLOUDS & RAIN SHOWERS PREVAILED ALONG THE ROUTE. THOUGH THE PLT WAS NOT BRIEFED ABOUT TSTMS, ONLY WIDELY SCATTERED TSTMS WITH MODERATE RAINSHOWERS WERE FORECAST.
