As bad as it might look for much of the country, I think there are still plenty of reasons to remain hopeful. Some of that cloud is scattered rather than overcast, or high-level cirrus which won't completely obscure the Sun, or convection which, if not too big, may dissipate as the Sun goes away. (Remember that ALL of these forecast models do NOT account for the loss of sunlight!) So even if it puts clouds in your area, you may still get a view.
I also like the probabilistic forecasts for mostly clear skies, as this gives a bit better indication of how likely you'll see the Sun, and of the uncertainties in the forecast. The clear/scattered/broken/overcast displays coming soon will also give a good idea of what to expect. And of course, check up with the meteorologist's local forecasts.
