The big difference between today and yesterday is, unlike yesterday, there's no promise of sunshine today. Due to the lack of sun, we'll be almost ten degrees cooler this afternoon. Highs will be in the 50s. Not only will Wednesday be the coolest day of the week, we'll probably see rain as well. We expect shower to be scattered across Texoma Wednesday morning. This will be our best chance of rain for the week. High temperatures will be in the mid and upper 40s. A welcome warm up begins Thursday and the warmest temperatures of the week come this weekend when highs will be six five to seventy degrees.
