One more scorcher on Wednesday, then more comfortable air moves in

This is an archived article and the information in the article may be outdated. Please look at the time stamp on the story to see when it was last updated.

This has been a hot summer by every measure we have.

  • Forty-one days with a high of 95ºF or higher in Huntsville (13th-most on record).
  • Second-hottest over-all average June to August temperature: 82.3ºF.

And there’s at least one more of the really hot days ahead before we get a breather.

The chance of showers and storms is only 10-20% on Wednesday and Thursday; consider yourself lucky if you get a quarter-inch of rain or more because most Tennessee Valley communities won’t get a drop before less humid, slightly less torrid air moves in on Friday.  We’re actually setting up nicely for high school football this week: rain-free and comfortable in regular “light” clothing.

Bone dry outlook: Need rain? This is not the time of year to expect a lot of it. Historically, late August and early September ranks among the driest periods of the year. Between now and September 15th, some model guidance gives us almost zero chance of measurable rainfall. Even in a historical dry period of the year like this, that’s unusual.

Only 12 times in 121 years has Huntsville measured less than 0.25” between August 30th and September 15th. Long-range outlooks can change a lot, so we’ll keep our fingers crossed that this outlook gets rainier instead of drier!

Guidance from NOAA’s CPC concurs with that sentiment: well-below normal rainfall through early September.

This is of course very bad news for crops in Alabama and Tennessee that are already struggling.  Cotton, soybean, and corn have grown well in a few areas and barely made a crop at all in others.

Remember, September and October are often very, very dry unless we have something coming in from the tropics to bring unusually heavy rain to the region!
