Above-Normal Temperatures Expected to Drop with Cold Front on the Way

We have officially entered late October, but that has not meant cooler fall temperatures for much of the central and eastern United States. A large dome of high pressure, sometimes referred to as a heat dome*, has settled over the region this week, causing above-normal temperatures. The heat is expected to continue through today (10/20) with some temperatures possibly reaching record highs in some areas.

However, according to NOAA's National Weather Service, much cooler weather is on the way as a strong cold front is set to sweep across the United States during the next couple of days.

This animation shows the predicted daily high temperatures for October 17-22, 2016, using data from NOAA's High-Resolution Rapid Refresh (HRRR) model. It clearly shows the expected cold front moving across the country, bringing heat relief to the central and eastern United States.

*A heat dome occurs when high pressure in the upper atmosphere acts as a lid, preventing hot air from escaping. The air is forced to sink back to the surface, warming even further on the way.
