Amy and I made it home by about 3PM.
True to my screen name, we took the "low road" under broken and ovc layers for a good portion of the route. A cold front paralleled the Iowa/Missouri border. South of the front, we experienced a mix of great thermal boosts provided by well-developed cumulus clouds, and isolated storms dumping out of other overdeveloped cu's. Bases were about 3000, and we had about 10kts on the tail at 2500. Visibility was never lower than 10 miles, except through the occasional rain shafts, which were sparse and easily avoided.
North of the front, a cloud layer started to form at 800 ft and we lost the tailwind. I initially decided to climb in search of more favorable winds, but in usual fashion, it didn't take long for the layer to form a near-solid undercast, so it was back down to the treetops for the last 120NM.
Remarkably, visibility under the low ceiling was over 50 statute miles. The only low-vis flying was in the last 15 miles of the trip, where a general area of mist reduced vis to about 4 miles. A quick chat with ATC for SVFR in to Ames, and we were safely on the ground.
It's interesting to note that, except for minor course deviations (less than 2 miles from our course line), we were able to make the entire trip without delay. The radar was peppered with activity through a good portion of our trip, but at every point along the way, the best option was always to proceed on course. I love XM! I think it adds more capability to low and slow aircraft than to the fast IFR birds, but I regard it as essential XC equipment in either.
Thanks to all of you for the great conversation as always. I second the remarks made by others on Steve See's successful effort to create an enjoyable Saturday evening event.
See you all next year! We'll plan to make the trip in speed and style in the RV4.
Matthew (and Amy)
