A thunderstorm Monday morning lowered temperatures to the upper 60s, poured buckets of rain on some areas and registered a trace at DFW Airport, and there's more to come.
The morning storm knocked out power to about 3,500 electricity customers in Tarrant County at around 10 a.m., Oncor spokeswoman Connie Piloto said. Within about an hour, that number had been reduced to 650.
Shortly after 1:30 p.m., more than 1,700 customers were shown to be without power, most of them in north Fort Worth, according to Oncor's online outage map.
Another storm expected Monday night could bring more cloud-to-ground lightning, a chance of hail and gusty winds to Tarrant County, said Matt Bishop of the National Weather Service's Fort Worth office.

The first round hit Benbrook early in the morning and reached Fort Worth between 7 and 7:30 a.m., Bishop said, briefly knocking out power in some areas, then drifting over and out of the city in about an hour. The storm dissipated into a light drizzle.
That storm produced cloud-to-ground lightning, Bishop said.
It was "nice to get some rain out of it, since we've been so hot and dry lately," he said.
The weather service previously reported that May was the second-hottest on record in Fort Worth and that rainfall was less than half the average for the month. MedStar reported treating 213 patients for heat-related conditions in May, about double the 106 patients treated in May 2017.
Temperatures are expected to get close to 90 Monday afternoon before a second round of storms arrives in Tarrant County overnight, Bishop said.
Tuesday morning could bring more showers and thunderstorms, with chances of rain tapering off through the afternoon and a high in the low 90s. Temperatures should rise slightly the rest of the week, with highs in the mid- to upper-90s and lows in the mid-70s, according to the weather service.
