Check out the low-level upper wind forecast (FD) for Ottawa tomorrow — it looks like the gales of November are coming calling a couple of days early:

In plain language, that means that at 18,000 ft the wind will be from the northwest at 97 knots (180 km/h). My Warrior cannot fly that high (the theoretical ceiling is around 14,000 ft, with a lightly-loaded plane and lots of patience), but many light piston singles and twins can. Even at 12,000 ft, the winds are strong enough that I could point the plane into the wind, drop flaps, pitch for slow flight, and fly backwards over Ottawa; at 9,000 ft, I could still pretty-much hover or move backwards very slowly.
