An August “cold front” is expected to cause numerous showers and storms to develop across the plateau for our Sunday. Indoor plans are recommended. Some of the rainfall could be heavy and a few storms could be strong, with gusty winds being the main threat. By Monday, the front slips farther south and reduces rain chances to 30%. Tuesday and Wednesday look mostly sunny and dry. I should note that if the front stalls out closer to our area than expected, storm chances will be introduced back into the forecast for Tuesday and Wednesday. Another frontal system begins approaching for the end of the week. That frontal system will lead to an increase in shower and storm chances once again.
