DFW actually tied the record high of 104*F yesterday, overachieving a bit. It was, however, 1 degree off the record maximum low of 82*F
Today's record is also 104*F, which could be tied/broke as well. The record maximum low is 79*F, which is looking to be shattered.
If 105*F+ can happen today through Friday, the recoed from 1980 will be broken. If it just happens Thursday & Friday, the record will be tied.
