Narrative:

I flew with 2 passengers from the chicago area to davenport, ia, for business. We arrived about xapm and planned on departing by xxpm. Conditions were forecast to deteriorate so we were hoping to leave on time. I received a briefing filed my IFR flight plan at X50 pm with ft dodge FSS. The conditions at davenport were not given but moline was reporting a 4000 ft ceiling and 7 mi visibility. In my opinion, it was worse than that, probably 3-5 mi visibility with light snow. I did my preflight, received moline ATIS as being 4000 overcast, 7 mi with light snow. Because davenport is an uncontrolled airport, I decided to pick up my clearance once airborne, which I did, I estimated visibility to be 3 mi, ceiling 2-3000 ft and light snow. After I picked up my clearance, I was informed by departure control to call the moline-quad city tower. Upon arrival and contacting the tower, the supervisor told me that an air national guard pilot on the field made a pilot report of conditions less than VFR. In that case, the control zone at davenport would be in effect, and I would be in violation of the far's. However, the only official information that I had was that given to me by the briefer, and my moline ATIS. I will admit that conditions were worsening, but I still felt that visibility was better than 3 mi. (I should also point out that I was not aware that I could pick up my clearance on the ground at davenport). The official WX observer at davenport reported at Y00 pm, conditions were 5000 overcast, 2 mi visibility with light snow and fog. At Y30 pm, he reported 5000 overcast, 2 mi visibility with light snow. The des moines flight standards district office is currently investigating the matter. Callback conversation with reporter revealed the following information. Reporter states he has had discussions with FSDO rep and recently received a letter of warning which means a letter will be in his records for 2 yrs. FAA rep agreed he did not have much choice but to use pilot judgement reference WX conditions. With ATIS 5 mi away reporting 4000 overcast and 7 mi visibility, he felt he was legal.
