After several weeks of being grounded due to low clouds, I was looking forward to the cool air, clear skies, high pressure and light winds that arrived this morning as forecasted. However, there is an AIRMET over the whole region for moderate turbulence, so I’m stuck on the ground yet again staring up at a sky that looks like perfect VFR flying weather but somehow isn’t.
The FAA books tell me that turbulence is due to unstable air, but I can’t piece together why it’s unstable today or, more importantly, how I could have predicted it. Which charts or other data should I be looking at, in particular days ahead of time so I know when is best to schedule a flight?
