Not Done with Summer

What a nice break we had from heat and humidity.  Temperatures did creep up today, but the humidity remained low.  In Nashville, dew points were in the low 50s all day.  That is in the refreshing category on the muggy meter.

But we are not done with summer humidity just yet.  As the winds kick around to a more southerly direction, the humidity will begin to move back in.  On the water vapor satellite imagery you can see the moisture just to the south of Tennessee. Water vapor imagery is a type of satellite data that is used to analyze the presence and movement of water vapor moisture in the upper and middle levels of the atmosphere. For us that means humidity will be on the rise tomorrow.

With that said, you can see the first folks to get the moisture will be across the southeast corner of Middle Tennessee. This will set the stage for a few showers and thunderstorms to fire off. This Futurecast Model shows how they would most likely develop during the afternoon.

The chances of rain will be about 20% each day until Friday, by then a few spotty showers and thunderstorms will be likely.

Saturday and Sunday, the chance of rain will be even greater…40-50% of scattered showers and thunderstorms.  But that will also help drop the temperatures back to the low 80s.

Fall is usually a quite weather time of the year, so we want to use this time to get you ready for when the weather is not so quite.  We are just over 3 weeks away from the fall series of Surviving the Storm.  Here’s is where we are headed next month.  I hope you and your family can make it to one of our events…it’s free.
