The heat wave washed out Monday.Almost as soon as the temperature climbed to a high of 101 on Monday afternoon, scattered thunderstorms moved in, cooling the air but also bringing wind and lots of lightning.One lightning strike reportedly ignited a house fire in McKinney. Monday was the second consecutive day of triple-digit heat at Dallas/Fort Worth Airport. Sunday’s high of 100, the first time the mercury reached the century mark this summer, was the latest date that DFW has reached triple digits since 2007.And it didn’t last long.Forecasters issued severe thunderstorms warnings Monday afternoon. Gusts of 60 mph were reported in Fort Worth.About 10 p.m., Oncor reported 25,000 customers without power — 19,000 in Dallas County and 6,000 in Tarrant County.“These were all short-lived storms that weakened as they went moved across the area,” said Matt Bishop, a meteorologist at the National Weather Service office in Fort Worth.The Star-Telegram rain reporters called in totals including 0.45 inch of rain in Benbrook, 0.52 in Forest Hill, 0.47 in Wedgwood and 0.13 in the TCU area.By 5:30 p.m. Monday, DFW Airport had received just a trace of rain, but the amount was expected to increase Monday evening.There was even brief street flooding in Bedford.This morning, a cold front is expected to arrive.By Tuesday afternoon, highs should be back in the lower 90s and then dip into the 80s on Thursday and Friday.The best chances for more rain are 70 percent Wednesday night and 60 percent Thursday, said Lamont Bain, a weather service meteorologist.“In general, we could see a few inches or so of rain, but some areas north of the Metroplex could see as much as 3 inches,” Bain said. “We could see some pretty beneficial rains.”The milder weather may stick around until the weekend.Whether we will go back to hot, dry weather next week remains to be seen.Some forecast models show that the high pressure system that typically parks over Texas and brings baking heat may stay off to the west next week.“Sometimes that pattern brings nocturnal showers and thunderstorms, but we’ll just have to wait and see,” Bain said.
