It’s been a sizzling and seemingly rain-free summer for Texas so far. That’s all changing for this last full week of the month, Aug. 22-26.

The “heat high” that has plagued the Lone Star State this summer is nowhere to be found this week. That has allowed for a weather pattern change to take effect, which will result in periods of heavy rain and lower temperatures Monday through Friday.

Scattered to numerous showers and thunderstorms will occur across North, West and Central Texas on Monday and Tuesday. Monday is expected to be the day with the highest coverage of rain across Oncor’s service territory. Monday is also the day that flooding is also most likely to occur across parts of the Metroplex.

Scattered rain is anticipated again Tuesday with the focus for the heaviest rain across Central and East Texas.

By Wednesday, rain chances will hit a bit of a lull and things will trend drier Thursday and Friday. Isolated shower and thunderstorm activity will still be possible, but the overall coverage of rain will be much lower.

Widespread rainfall totals on the order of 3-5 inches can be expected from late Sunday through Friday. However, there will be some isolated locations across Oncor’s service territory that will see more than 7 inches of rain this week – with most of that falling on Monday and Tuesday.

Any thunderstorms this week – particularly Monday and Tuesday – could produce very heavy rain and move slowly. Flooding issues should be anticipated and we urge our customers to be very cautious when driving. You should never attempt to drive over a flooded roadway. Storms will also be capable of lightning and gusty winds. As always, Oncor teams will be ready to respond to any outages caused by weather.

Thanks to the rain chances and increased cloud cover, high temperatures this week will generally be in the 80s and 90s. You read that right – no 100-degree weather!

Stay safe this week.
