Flights are trending closer to dark or at dark as is typical after mid-May Today’s Predicted Average Temperature is 87.5°F Normally, if the day’s Predicted Average Temperature is over 55°F but below 90°F with light winds, then there’s a chance for a strong flight. However, the Congress bats are giving birth these days and flights will be diminished, unless a north front moves through that stirs up insect activity.
