Cool and Dry Pattern Will Briefly Replace Muggy Airmass Early Next Week

As I alluded to in yesterday’s article, a cooler and considerably less humid airmass will replace the stormy and humid one this weekend. Deep, southwesterly flow currently extends from Texas to the Mid-Atlantic. With low-level southerly and southeasterly flow south of a stationary front draped from southeast Texas to Virginia, the atmosphere has remained moisture-laden. Any embedded disturbance within the deep-layer southwesterly flow has continued to favor the development of storms capable of producing heavy rainfall rates for quite a few.

A strong shortwave trough currently moving into the Northern Plains will trek eastward and usher in a pattern change. By early next week, the stationary front will push out, and a longwave trough will temporarily be placed over the eastern U.S. This type of pattern favors cooler and less humid conditions. Temperatures will still reach the 70s and 80s during the day across the South, but nighttime temperatures will actually be a bit chilly. The Northeastern U.S. will eventually have the coolest conditions once the upper-level low passes across the region around mid-week.

Enjoy it while you can. Expect a warming trend from west to east late week into early next weekend.
