These maps show yesterday’s high and low temperatures around the U.S., as well as the current temperatures and the 24-hour temperature change (the temperature difference between now and yesterday at the same time).
Data Update Cycle: The maps for current temperature and the 24-hour change are updated at 20 minutes past the top of each hour. The other maps (yesterday’s high and low temperature, and today’s normal temperature) are updated each morning at approximately 7 am EDT. If you continue to see old maps after the scheduled update times, you may need to clear the browser cache.
