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.
