Epic Heat Wave to End in Texas!

The cooler air headed to Texas will be pushing through the Plains this weekend.

Even if a future tropical system fails to grace Texas with needed rain, signs are pointing toward all of the southern Plains receiving another gift from Mother Nature this holiday weekend--cooler air.

Earlier in August, AccuWeather.com Meteorologist Brian Edwards reported that there were essentially two ways to release the extreme heat's firm grip on the southern Plains.

One scenario stated by Edwards was the arrival of a tropical system, with the second being a cold front plummeting southward.

While uncertainty remains with the track of Tropical Storm Lee in the Gulf of Mexico in upcoming days will track into Texas, a cold front is destined to arrive.

According to Expert Senior Meteorologist Brett Anderson, "The first significant cold front of the season will drop south through the region Saturday through Monday, dropping daytime temperatures anywhere from 15 to 25 degrees."

Instead of enduring triple-digit heat, as will still be the case for the next few days, Oklahoma and northern Texas will enjoy highs in the 80s, if not lower, Labor Day.

Dallas is expected to record highs in the upper 80s Labor Day. Temperatures have not been held to that mark since August 13, when rain and clouds blanketed the city.

Temperatures could even stay in the 70s not just Labor Day, but also Sunday throughout far northern Oklahoma and the Texas Panhandle.

The nighttime hours may actually feel cool to some residents across this region later in the holiday weekend as temperatures dip into the 50s.

According to Meteorologist Mark Mancuso, "Some locations in central and northern Texas could even dip to record-challenging levels during the early morning hours early next week!"

The bone-dry ground and air over Texas not only allows for extreme heat in a warm air mass, but extreme chill in a cool air mass.

It seems fitting that blazing heat will release its grip on the southern Plains by Labor Day, since the holiday unofficially marks the end to summer.
