Liz,
Cornell has a good site for the summary of this information, and it allows
you to select the date.
This is smoothed national level data but they include arrows showing
predominant migrant direction.

However, the "Raw" National Mosaic Loop really is the best way to "see" big
movements when conditions are right. You can nearly time sunset with
increased noise on clear evening using the Doppler. When no rain is present
look for the "fuzzy balls" around the radar sites. The "fuzz" is the
signature of migrants (bats and insects too!)

I've used the data to identify and track emerging Mexican free-tailed bats
from their cave roosts in Texas, and seen enormous insects hatches on the
Mississippi. Very cool stuff. But more useful where there are less
mountains to block the beam.
