The heat dome currently situated over the northern plains will move east, into the midwest and south, establishing a heat wave for another record week of high temperatures in the United States and shortening the heat relief that many of these states will get into the weekend, according to CNN.
St. Louis was forecast to have a high temperature of 84 degrees F on Saturday. By the time Tuesday arrives, the temperature will rise to 100 degrees. Chicago’s high temperature on Saturday may not even reach 70 degrees, but by Monday, the high temperature will soar to 95 degrees.
More than 50 million Americans are in line to experience temperatures above 100 degreesand heat advisories and excessive heat watches and warnings are likely to be issued as the event approaches, according to The Washington Post.
The heat wave forecast by the National Weather Service (NWS) It comes less than a week after much of the Southwest, plains and valleys of Ohio and Tennessee grappled with sweltering heat and humidity.
It all stems from the same main heat dome that has been languishing and refusing to budge from its perch over North America.
This heat dome has entered the western United States and is expected to spread to the continental states with a high pressure ridge over the next week.
The next big heat pulse will set in on Tuesday of next week and will really dominate starting Wednesday.
The highest temperatures compared to normal will be in the northern/central plains and upper Midwest, where high temperatures will be 20 to 30 degrees above average and rise into the upper 90s and 100s.
Excessive heat watches and heat advisories have been posted due to maximum heat indices that can range between 100 and 110 degrees in the next few days.
The Weather Prediction Center continues to forecast elevated temperatures for much of the continental United States through the coming week. Heat domes are ordinary summer staples, but they’re getting more intense by human-induced climate change.
