Mid-September weekend weather - not quite to "summer" levels

I promised that summer was over with our last big cold front. I still maintain that, though it'll get within a few degrees of my "summer threshold" this weekend ahead of another cold front that moves through Sunday!

There are a lot of outdoor activities this weekend, including the Memphis Tigers football game Saturday evening vs. MTSU (Go Tigers!), the start of the Mid-South Fair at the Landers Center in DeSot County, and the 3rd annual Best Memphis Burger Fest at Minglewood Hall among others. Normally mid-September highs are in the mid 80s and lows in the mid 60s. A warm airmass ahead of the cold front will mean temps slightly above average. In fact, we could push 90 degrees Saturday afternoon with upper 80s on Sunday as the front moves through the region. Humidity levels will also be elevated  with dewpoints in the mid 60s, but not quite to the "summer" threshold.

Dewpoints this evening are high enough to notice some humidity in the air.

The cold front Sunday will bring a chance of afternoon thunderstorms, but right now we put that rain chance at just 30%. No severe weather is expected and it should not deter you from carrying on with your plans. You might just keep an umbrella close by in case a passing storm moves overhead!

Average rainfall expected on Sunday as the front moves through. Scattered t'storms are expected mainly in the afternoon.

By Monday, cooler and drier air seeps in with dewpoints falling into the comfortable range in the 50s, mostly sunny skies, and highs near 80. The rest of next week looks mighty fine with abundant sunshine through at least Thursday, highs in the low to mid 80s and lows generally in the 60s, though many areas will see upper 50s on Tuesday morning.

Dewpoints on Monday evening are much more comfortable behind the front.

Hope everyone has a fantastic weekend! And in honor of "International Talk Like Like a Pirate Day"...
