The coldest time of day can shift considerably if we have fronts moving through, varying winds and cloud cover or precipitation starting and stopping during the night or morning. However, assuming we have a more tranquil pattern, as we frequently do, with fair skies and light winds late at night and early in the day, the lowest temperature usually occurs a little after sunrise, sometimes as much as a half hour to an hour later.
