Hot with some scattered storms on Saturday

Scattered heavy downpours develop around Alabama and Tennessee again on Saturday.  The day starts out warm and humid, and while rain is not “likely” before noon, a few showers are possible.

The Heat Advisory is still in effect even though temperatures come down considerably from Thursday’s high of 100ºF.  Expect a “feels like” temp as high as 105ºF by mid-afternoon unless you’re lucky enough to get a cooling downpour.

Weekend specifics: Two features hold sway over the weather here this weekend: a strong, hot area of high pressure and a weak upper-air disturbance nearby. That disturbance caused numerous showers and storms around the region Friday, and although the biggest influence should be south of the Valley on Saturday, it’s still close enough to kick off some widely scattered, occasionally heavy storms.

So how can you plan for that?

Go about your business as usual, but if you are in a vulnerable position like on a lake, at a pool, golf course, middle of a park, etc., make sure you have Live Alert 19 on your mobile device so you can get up-to-the-minute information on any storms that develop around you.

Rain chances are part confidence and part coverage; we are confident that there will be storms in North Alabama and Southern Tennessee on Saturday and Sunday. We are also confident that it will not be an evenly-distributed rainfall; some get a load of rain, some get left bone dry.

Think it’s been hot this summer?  

You’re right.  Summer 2016 has been the 9th-hottest on record so far (using daytime high temperatures as the measuring stick).  The average daytime high temperature since June 1st in Huntsville has been 93.5ºF; that’s 3.6ºF above the most recent climatological average.

We have also already fulfilled the yearly quota of 90-degree heat.  In a “normal” year, Huntsville would have about 45 days with a high at or above 90ºF.  In 2016, Friday’s high of 96ºF made the forty-fifth day of the season with forty days left in meteorological summer (June 1 to September 1).
