By Thursday morning the front and trough aloft should be over
eastern CO and moving into the plains states. This will bring cool

weakening westerly flow and dry conditions will continue through
Friday and Saturday.

On Sunday another strong Pacific trough will develop along the
west coast with high pressure over the midwest and western Gulf of
Mexico. The position of these system will help pull moisture

thunderstorms each afternoon. By Tuesday afternoon the Pacific
storm may be quite strong with its cold front moving through Utah.
