Full-Blown Heat Wave into Next Week
5:00 pm Mon 16 July 2018
A weak front is draped across central Oklahoma and it fired up a handful of thunderstorms today. I will keep a low-end chance of a thunderstorm in tomorrow’s forecast due to the same feature at 20 percent.
An upper ridge now centered to our west extends its influence eastward over Texoma as the week progresses; the front fizzles and surface winds turn southwesterly. These three effects collaborate to create a major heat wave with maximum temperatures soaring above 100 for all locations from Wednesday into the weekend.
Overnight lows will probably remain 80-or-better from Thursday through the weekend, reaching Heat Advisory or even Excessive Heat Warning criteria. This will be an extended period of very hot weather so do all you can to stay cool!
