Wider weather episode

Triple digit daytime temperatures and warm overnight lows gripped nearly all of north Texas for the entire month of July. A few records for daily high temperatures were set or tied, but several records for highest minimum temperatures were set. Dallas/Fort Worth set a new all-time record highest minimum temperature of 86 degrees on the 26th. The prolonged heat took its toll on North Texans and there were 15 heat related deaths; most of them occurring in Dallas County. There were many more heat related illnesses. A Heat Advisory was in effect from the 11th through the 18th, and then again from the 23rd through the end of the month. The triple digit heat this month began a streak that would challenge previous records for most consecutive 100 degree days and greatest annual 100 degree days.
