Problem out west is that the SID's often require performance that many piston planes don't have. For example Jimpa Two at Carson City (KCXP) requires a minimum climb rate of 550' per NM to 11400'. So assume you climb at 120 knots, that's 1100ft/min all the way up to 11400.' Most normally...
Flying in the morning is a way minimize exposure to the build-ups. Once the build-ups start...building...up...it gets bumpy and more challenging. Isolated/scattered t-storms are just that and generally visually avoidable. If not, time to change plans and land.
I heard "Cessna XYZ on short final, runway 26, Stead...what's that on the runway...is that a coyote...well frick...Cessna XYZ, going around, right traffic runway 26 Stead."
Wait a minute...that was me. Never mind.
