The hottest summer on record brought more than 60-plus days of 100-degree-or-higher temperatures, along with the hottest July and August on record for Texoma. Rainfall was also extremely scarce with amounts generally less than 25% of average for the period June to August.
A major pattern change will allow Texoma to sample some fine early fall weather as we move into the Labor day Holiday and the days that follow.
A deep upper air trough will push a Canadian air mass southward into the southern Plains Sunday. The core of the milder air mass will move eastward rather slowly, allowing the east to northeast low-level flow through Texoma skies for several days (discussion continues below map).
A tropical system along the Gulf coast has a very low chance of bringing any rain to Texoma, since the front and high pressure will effectively block a movement in our direction. In fact, northeasterly winds around the "top" of the tropical system will help to further reduce the potential for any heavy rainfall.
So very little rain is expected with the front, but the odds for a major cool-down are in the “high confidence” zone.
