Extreme Heat In The Garden

Hey Y'all!  
We are experiencing intense heat here in Middle Georgia  (USDA zone 8a).  We are in the upper 90s now.  Triple digits starting this weekend.  This is crazy hot for the month of May!  
My yellow squash was just beginning to blossom.  I planted my tomatoes, eggplants and okra earlier than normal,  trying to beat the intense summer heat.  Oh the IRONY!
Now they are all struggling.  

I don't expect any of them to grow or thrive during this time.  I'm sure they are redirecting their energy into just surviving.
What can I do to help my garden to survive this type of heatwave?
No rain is in the forecast.  So I'm watering extra and I've added mulch to the garden.  Should I hold off feeding/fertilizing until the intense heat passes?
Any other suggestions?  

Have you tried shading them?

Shade is very helpful, especially from the Western sun.

Shade. Mmm...makes sense.  I can do that. Some plants are in containers and can be moved.  Thanks!
