Along with a Home Depot light(as per Eddie's description) above for subject lighting.
I should also add that I diffuse those lights only because they are 2 feet from my face and they are too harsh without the diffusion. If you set them 6 feet away from you they will be fine. With your plan for time of day you may not need supplemental lighting. You may want to light your backdrop to eliminate shadows, but again, you won't know until you test if that natural light will cause enough shadows to worry about.
