Narrative:

I recieved a WX briefing from columbia FSS in sioux city that reported 4600 scattered 10000 overcast conditions at cedar rapids. I was 40 NM away when I entered a break in the clouds at about 8500' only to find 1 mi visibility in heavy rain and overcast. I executed a 180 degree turn to find the hole to return but it had closed. I then initiated a climb in IMC to approximately 13500' until regaining VMC conditions. I declared an emergency approximately 2 min prior to resuming VFR as I was unsure of my location and was not able to raise FSS on any frequency except 121.5. I was assigned a transponder code for traffic avoidance and given a DF steer to guide me back to ft dodge. I feel the cause of my problem was two-fold; entry into a marginal VFR conditions and poor WX dissemination and reporting by FSS. Also poor radio reception was factor. Better judgement on my part as to near time WX decisions will become a part of my flying in the future and an upgrade in radios will be accomplished on my aircraft. I also feel that video depiction of WX phenomena at sioux city would have caused me to postpone that flight. My alliance of FSS WX briefings will not carry the same weight on my decisions as it had in the past. I would like to see more area type briefings and pc type terminals in more airports.

Title: VFR IN IMC FOR SMA.

Narrative: I RECIEVED A WX BRIEFING FROM COLUMBIA FSS IN SIOUX CITY THAT RPTED 4600 SCATTERED 10000 OVCST CONDITIONS AT CEDAR RAPIDS. I WAS 40 NM AWAY WHEN I ENTERED A BREAK IN THE CLOUDS AT ABOUT 8500' ONLY TO FIND 1 MI VISIBILITY IN HVY RAIN AND OVCST. I EXECUTED A 180 DEG TURN TO FIND THE HOLE TO RETURN BUT IT HAD CLOSED. I THEN INITIATED A CLB IN IMC TO APPROX 13500' UNTIL REGAINING VMC CONDITIONS. I DECLARED AN EMER APPROX 2 MIN PRIOR TO RESUMING VFR AS I WAS UNSURE OF MY LOCATION AND WAS NOT ABLE TO RAISE FSS ON ANY FREQ EXCEPT 121.5. I WAS ASSIGNED A XPONDER CODE FOR TFC AVOIDANCE AND GIVEN A DF STEER TO GUIDE ME BACK TO FT DODGE. I FEEL THE CAUSE OF MY PROB WAS TWO-FOLD; ENTRY INTO A MARGINAL VFR CONDITIONS AND POOR WX DISSEMINATION AND RPTING BY FSS. ALSO POOR RADIO RECEPTION WAS FACTOR. BETTER JUDGEMENT ON MY PART AS TO NEAR TIME WX DECISIONS WILL BECOME A PART OF MY FLYING IN THE FUTURE AND AN UPGRADE IN RADIOS WILL BE ACCOMPLISHED ON MY ACFT. I ALSO FEEL THAT VIDEO DEPICTION OF WX PHENOMENA AT SIOUX CITY WOULD HAVE CAUSED ME TO POSTPONE THAT FLT. MY ALLIANCE OF FSS WX BRIEFINGS WILL NOT CARRY THE SAME WT ON MY DECISIONS AS IT HAD IN THE PAST. I WOULD LIKE TO SEE MORE AREA TYPE BRIEFINGS AND PC TYPE TERMINALS IN MORE ARPTS.
