After a warm and dry Monday, there is a chance of rain every day through the end of the week as a pair of storms move through Utah.

A weak storm will move north from southern California to Utah on Tuesday, according to the National Weather Service, bringing with it the threat of brief bursts of heavy rain that could cause flash flooding in southern Utah on Tuesday.
