Unexpected worsening of the weather conditions can be a pain especially if you have already planned an outdoor activity like camping or hiking. In order to avoid having a trip being spoiled by the weather, you should know some basic principles of meteorology. If you're coming to Zion you need to be prepared for changes in the weather, but sometimes weather and storms can make for a more exciting and beautiful Zion trip, and sometimes they can ruin them.
Forecasting weather can mostly be done by “reading” the sky. For example, denser and descending clouds means that the weather condition will not be good and may very likely suggest a rain or worse, storm. The same conclusion can be made from thick clouds. A deep blue sky is a good sign. If the sky is reddish or bluish and the wind blows from north-west the weather may not be good later in the day. If the sky, on the other hand is greyish or reddish in the nighttime then it means a good weather.
Forecasting the weather with the help of the wind pressure
Not only the sky can help you predict the weather but also the wind pressure. A steady drop on the air pressure or air density suggests that as winds blow into a low pressure, the air moves up. This upward flow of air can cause clouds and precipitation to form. Which is not good news if you are planning for an outdoor trip.
Another good sign of a worsening weather condition: wet fog
From a panoramic view of the environment, the sight of a wet fog may look good but this suggests a coming of a bad weather. Wet fogs on the mountain and on the rocks likewise suggest worsening of a weather condition.
