The K-index is +17. You should expect

• A. Poor soaring conditions with possible showers
• B. Good soaring in the afternoon with a chance of showers
• C. Clear blue skies with no wind
• D. Thunderstorms all day

Answer: (B)

Convective potential is what the K-index measures. It combines surface temperature, surface dew point, and mid‑level temperatures to estimate how much moisture and instability the atmosphere has to produce convection and potential thunderstorms. A K-index of +17 means there’s enough daytime heating and moisture for rising air to form usable thermals in the afternoon. So you can expect good soaring as the day heats up, with a chance of showers from convection. It’s not just clear blue skies, and it’s not likely that thunderstorms would dominate all day.
