Arlington is again under an Excessive Heat Warning today (Wednesday).

Heat index values of up to 110 are expected, making time spent outdoor potentially hazardous. As a result, Arlington’s Dept. of Parks and Recreation has again cancelled outdoor programming between noon and 8 p.m. today.

Storms are also possible later today, starting in the late afternoon.

Relief from the heat looks elusive, with a rainy and cloudy day on Friday keeping the high temperature to the low 80s. Beyond that, the 90s return Saturday and are expected to stick around until at least the middle of next week. Triple digit temperatures are even possible on Tuesday.
