Another dangerously hot afternoon and early evening is expected to begin the weekend, with triple digit high temperatures and heat indices upwards of 111 degrees across portions of northern and central Oklahoma.
An approaching summer cold front will serve as the focus for scattered showers & thunderstorms this afternoon into the overnight with chances increasing Sunday afternoon as the front moves through. Isolated storms on Sunday could produce some strong winds.
Our ongoing late summer heatwave shows no signs of breaking anytime soon, with triple-digit heat expected for most into next week. A weak front will help "cool" temperatures a few degrees across northern Oklahoma on Sunday and Monday.
Know the signs of your body overheating before it becomes to late.
A persistent hot and dry pattern will elevate fire weather conditions this afternoon across northwest Oklahoma with elevated conditions returning for Tuesday & Wednesday across all of western Oklahoma and western north Texas.

Local Weather History For August 15th...
Some of the worst flooding that ever occurred in western north Texas
happened on August 15, 1971. Heavy rain began on the 14th, but the
worst of the rain and most of the flooding was on the 15th. On that
day, rainfall averaged four to 11 inches. At least 10 families were
forced to evacuate their homes along the Wichita River as the water
rapidly rose. The river rose so high that its swift-flowing waters
undercut several streets, causing them to collapse. The official
rainfall at the National Weather Service Office in Wichita Falls on
the 15th was 4.52 inches, making this the wettest August day ever
observed in the city.
