In general, this period looks to be as hot as it generally gets in the area.
Typical days of +86 per year. (Map is not perfect, but a ballpark idea in area) In general the highest Wv spots rarely top 80.. Fair shot at that, this weekend.

** Car thermometers, bank/store thermometers will likely read higher than reality during this period. Lots of heat, radation reflecting back off artificial surfaces, objects.

Max temps off the 12z ECMWF with heat indecies Fri-Mon. The GFS has consistently been hotter than the ECMWF. What will likely occur is open, and town areas lean towards GFS, higher, wooded, rural areas lean towards the ECMWF.

Looking further out, models are hinting at a July temp turnaround. Both the new Euro weeklies just in tonight and the CFSV2 evolve the pattern in a very similar way over the coming several weeks.
