It's certainly the time of year when I start paying close attention to temeratures aloft. That Friday was a sort of a drizzly, rainy day so I wanted to see forecasts above freezing for my intended route.
I was expecting to depart KBDR between 20Z and 21Z, and the TAF was forecasting basic conditions of six miles visibility in mist with a broken ceiling between 2500 and 3500 feet, but with periods of light showers and four mile visibility, ceiling at 1500.

I was anticipating about 2:35 enroute, with an arrival at KVKX a bit after 23Z. But the forecast for nearby KDCA was quite benign...calling for good visibility and scattered clouds at 15000 feet. Clearly, it seemed, I was headed for better weather.

Looking ahead, I could see that there were cells in the vicinity of Andrews AFB, just north of KVKX, my destination. It would, I figured, take me about another twenty minutes to get down to a point abeam OTT and I hoped that the active weather would clear to the north by then.
Approaching OTT, I asked for the RNAV Runway 6 instrument approach into KVKX. It looked as though the active cells had moved away from the airfield, but I saw no reason to chance that cloud "debris" from the cells would hamper a visual approach. And, the extra 15 minutes or so that it would take to fly the approach would give the weather some extra time to move away. Sort of a useful delaying vector.
The approach was uneventful. The weather had moved off to the north and the final approach and landing offered no problems. I taxied N631S around to the hangar and put the airplane to bed.
Only after closing the hangar doors did I notice that in the half-hour since the wheels had touched the runway a serious layer of fog had settled over KVKX. If I'd been thirty minutes later, I doubt I could have landed there. Timing is, as usual, everything.
