It’s been a very warm and even record-breaking end to the month of May. Now that June is here, which is the first month of meteorological summer, not much will change. Through at least the first half of June, temperatures will remain above average across the Central US overall as a persistent upper-level ridge of high pressure remains centered over the region. This is a super strong ridge with heights of at least 591 decameters (dm) over at least the Southern Plains. These geopotential heights signify how strong different pressures are. A greater geopotential height, like in this event, a warmer air mass. Once we get to values in that 591 dm range, that tells forecasters that it will definitely be hot.

Due to the passage of a cold front across the Northern Plains, temperatures will actually become below average during the weekend, aiding in much-welcome relief from the heat and humidity. Temperatures in this region will be up to 20 degrees below normal while the Southern Plains continues to bake at levels of up to 20 degrees above normal on Saturday. Actual high temperatures will be in the 70s across the northern half of the Central US while to the south it will mainly be in the 90s and 100s. Numerous locations in Texas will likely break record high temperatures as well.

On Sunday, warmer air will begin to surge back into the Northern Plains while the brief round of cooler air infiltrates the Upper Midwest and Great Lakes. Temperatures across the Plains will be near to up to 15 degrees above average before the ridge re-intensifes and centers itself over the Central US during the start of next week. High temperatures on Sunday will be in the 70s and 80s across the Northern and Central Plains and up to the 90s in the Southern Plains. The 100-plus degree highs will be limited to southern Texas and parts of the western Gulf Coast.

During the start of next week, the warmth and humidity will continue to flow back toward the north, allowing for widespread high temperatures of 10 to 20 degrees above average. That will make actual highs in the 80s, 90s, and 100s almost a daily occurrence during the new work week.
