Narrative:

We were trying to stay VFR through lit airspace; but we could not stay that way. ZME told us that lit had 800 ft scattered; 2500 ft broken and 5000 ft overcast. However; that didn't work out. We ended up at 500-1000 ft AGL to stay clear of clouds. I finally gave up and requested a clearance for an approach to lit as the clouds and rain made it impossible to continue to our destination. We were given a clearance to 4000 ft MSL for radar vectors to the ILS 4L at lit airport upon reaching 4000 ft MSL. We were enough on top that I canceled the approach clearance to lit and requested an IFR clearance on to our destination; plk; at 10000 ft MSL. The flight was uneventful after that. The reason for trying to stay VFR was that we did not have WX radar. ZME gave us a bad WX report for lit which sucked us into a bad scenario of having to fly lower than we would have liked to. Fortunately; when I decided to accept the IFR clearance the WX was mostly rain with no embedded high level thunderstorms.

Title: DC3 FLT CREW WHILE VFR ENCOUNTERS UNFORECAST WX AND REQUESTS IFR CLRNC TO NEAREST FIELD. AFTER CLB; FLT CREW ENCOUNTERS VFR AND CONTINUES TO DEST.

Narrative: WE WERE TRYING TO STAY VFR THROUGH LIT AIRSPACE; BUT WE COULD NOT STAY THAT WAY. ZME TOLD US THAT LIT HAD 800 FT SCATTERED; 2500 FT BROKEN AND 5000 FT OVCST. HOWEVER; THAT DIDN'T WORK OUT. WE ENDED UP AT 500-1000 FT AGL TO STAY CLR OF CLOUDS. I FINALLY GAVE UP AND REQUESTED A CLRNC FOR AN APCH TO LIT AS THE CLOUDS AND RAIN MADE IT IMPOSSIBLE TO CONTINUE TO OUR DEST. WE WERE GIVEN A CLRNC TO 4000 FT MSL FOR RADAR VECTORS TO THE ILS 4L AT LIT ARPT UPON REACHING 4000 FT MSL. WE WERE ENOUGH ON TOP THAT I CANCELED THE APCH CLRNC TO LIT AND REQUESTED AN IFR CLRNC ON TO OUR DEST; PLK; AT 10000 FT MSL. THE FLT WAS UNEVENTFUL AFTER THAT. THE REASON FOR TRYING TO STAY VFR WAS THAT WE DID NOT HAVE WX RADAR. ZME GAVE US A BAD WX RPT FOR LIT WHICH SUCKED US INTO A BAD SCENARIO OF HAVING TO FLY LOWER THAN WE WOULD HAVE LIKED TO. FORTUNATELY; WHEN I DECIDED TO ACCEPT THE IFR CLRNC THE WX WAS MOSTLY RAIN WITH NO EMBEDDED HIGH LEVEL TSTMS.
