I drove past the crash site at about 15:05. The weather was 8/8 clag to the deck. I was on my way back from work and had been surprised all day that the freezing level was well above the safety altitude in that area. Surface temp was around 7-8 degrees and I had 3 at 2 400'.
I fly that area most days and often find visibility/cloud base around the ridge area can be far lower than the Benson area due to orographic effect. I flew 4 ILS on Sunday in different parts of the country, and three of them within 30 miles of the crash site were to minimums.
