Music City Mall — Lewisville was jam-packed the evening of Oct. 31 as Lewisville residents scrambled to find a place to trick-or-treat indoors and avoid that afternoon’s harsh showers.

Though the mall’s event was scheduled to run from 6 to 8 p.m., revellers reportedly showed up soon after 5 p.m., and most stores were completely drained of candy shortly after 6. The shortage drove online vitriol against the mall. However, the rains ended early in the evening, and many Lewisville residents reported a rich night of traditional neighborhood candy seeking.

Mall general manager Natalie Boyer said she plans to turn Malloween into an annual event.

“We are so excited to bring something unexpected and magical to Christmas this year,” Boyer said in a statement. “We can’t wait for our next big event — Santa arriving at the mall in a way the DFW has never seen before!”

Santa Claus is scheduled to arrive at the mall by helicopter 10 a.m. Nov. 17 in the south parking lot.

The Halloween rains capped off what had already become the wettest October in DFW history a week beforehand. The final rainfall number, via the National Weather Service, was 15.66 inches on the month. October 1981 saw 14.18 inches of rain — accounting for more than 30 percent of DFW rainfall for that entire year — but no other October has seen more than 10 inches of rainfall going all the way back to 1898, according to National Weather Service data.

The intense precipitation lead to worry last week that Lewisville Lake might reach its capacity, but the Army Corps of Engineers found the opportunity to drain the flood pool over the weekend. As of 6 p.m. Nov. 3, the lake tops out at 528.35 feet above sea level with the flood pool 60 percent full.

DFW has experienced 50.56 inches of rainfall so far this year with two months left to go, and it’s been feast-or-famine from month to month. October accounted for more than 30 percent of the year’s rainfall so far, and February (11.31 inches) and September (12.69 inches) each represent more than 20 percent of the overall number. No other month has had even three inches.

The DFW record for annual precipitation is 62.61 inches, set just three years ago in 2015. With only 12.05 inches needed to reach that mark, another wet month in line with this year’s big three would be plenty to set the record. Even if it doesn’t hit the mark, 2018 is one of only seven years since 1898 in which DFW has seen more than 50 inches of rainfall.

DFW International Airport’s forecast for the next week calls for rain Nov. 3, 7 and 8.
