DFW only topped out at 98*F yesterday and 99*F today, so the 100*F drought continues...
Looks like the top 10 list for latest 1st 100*F days may be in play now (starting with 8/7). Meanwhile, 1973 and 1906 are the only years in recorded history thus far that DFW didn't see a single 100*F day.
BTW, the high of 98*F yesterday is also amongst the latest in the season DFW has recorded a temp that high, with the exception of 2002.
