The weathermen do their best, it is just not good enough.
There could be days of rain or cold without them warning us.
 At times at a class or any herding event it rained or we froze!.

Keep foul weather gear available to you at all times.
Training and trialing go on no matter the weather.
 The exception is if the facility is rendered unusable.
