Skies will be Mostly Sunny to Partly Cloudy, South breezes 5-15 mph, and a 10 % chance of a pop up Gusty Downpours.

Monday … the Upper Air Ridge retreats west over Denver Colorado. This westward shift will allow an upper air disturbance to ride around the northeast edge of the Upper High and across Texoma.
