High heat, humidity continues after DFW records first official 100-degree day; storms possible over weekend

North Texas has a slight chance of an isolated shower or thunderstorm this afternoon, with rain chances around 20%. Most activity will remain along and east of the I-35 corridor, with the best chances across East Texas. 

While coverage will be limited, a few storms could produce gusty winds, frequent lightning and brief heavy downpours. Any remaining showers and storms will diminish around sunset, leading to a calm and dry night.

Overnight, skies will become mostly clear with warm conditions continuing. Temperatures will fall into the middle 70s with light southerly winds.

As rain chances fade, a ridge of high pressure will build into the region, bringing a hotter and drier end to the workweek. High temperatures Thursday and Friday will climb to or near 100 degrees under mostly sunny skies. Heat index values between 100 and 105 degrees will make it feel even hotter during the afternoon hours.

The hot pattern will continue into Saturday, with highs once again reaching the upper 90s to around 100 degrees. A few isolated showers may develop late in the day across far southern counties as moisture returns.

Rain chances increase Sunday as a weak boundary settles into North Texas, bringing scattered showers and thunderstorms and providing some relief from the recent heat. The best opportunity for widespread rainfall currently appears to arrive Monday, when deeper moisture could support scattered to numerous showers and thunderstorms, along with locally heavy rainfall in some areas.

Monday is looking like the best chance for rain next week. Scattered to numerous showers and thunderstorms (40–60% chance) may develop as deeper moisture moves back into North Texas, continuing into Tuesday. Locally heavy rainfall will be possible if storms repeatedly move over the same areas. Highs remain in the lower to middle 90s.
