While Sept. 1 marked the start of meteorological fall, most of us have yet to feel anything close to fall temperatures, and more record heat ahead could leave some areas hoping for relief.

The first half of September has been the hottest on record for dozens of cities from Colorado and New Mexico to Virginia and North Carolina shown in the map above.

Among those are Austin, Dallas, Oklahoma City, San Antonio, Little Rock, Memphis, Nashville, Indianapolis, Cincinnati and Louisville.

Several cities could break daily record high temperature records this weekend.

Much of the Southern Plains and Southeast will have highs in the 90s through the weekend, with cities like Oklahoma City, Dallas, Little Rock and Nashville flirting with triple-digits.

Will there be any relief?

By the start of the new week, there will be relief for some — but not all.

Parts of Kansas, Missouri and Illinois will see highs in the 70s for many days in the week ahead. Parts of northwestern Oklahoma, northwestern Texas and northern Arkansas will finally dip into the 80s starting on Monday.

By mid-week, that heat relief will arrive in the Tennesseee Valley.

And, yes, there's even a smidge of relief for areas of the Deep South from Texas to the lower Mississippi Valley. By later in the week, highs could only reach the upper 80s or low 90s.

Looking a bit farther out, the Southern Plains has the best chance of continued warmer than average temperatures from next weekend through the end of the month, according to NOAA's Climate Prediction Center.
