Fast moving High Plains weather

Yesterday I awoke to a glorious, bright, sunny morning. It promised a balmy day of warmth and spring-time bliss. But off to the west it was very dark, a solid mass of dark blue from zenith right down to the ground. Within half an hour a deep, cold overcast had taken over, the wind came up, and it began to hail. In the next half hour the storm had moved on, the sun came out, and the afternoon developed just as the earlier morning had promised. Boredom tends not be a factor where weather in the 'Great American Desert' is concerned.
