Tonight: Isolated Showers Quickly End
Like clockwork, any rain will end quickly as we lose daytime heating this evening. Temperatures will fall through the low to mid 80s for any outdoor plans, but it will still be quite humid.
Thursday: Scattered Storms, Heaviest Stays South – High 91°
The chance for thunderstorms will increase slightly on Thursday in accordance with another slug of moisture that swings our way from the Gulf of Mexico. To better visualize this, check out the PWAT values (note: “PWAT” is short for precipitable water…known as the “measure of the depth of liquid water at the surface that would result after precipitating all of the water vapor in a vertical column over a given location…”).
Starting the loop Thursday afternoon, you can see the copious amounts of “rain-able water” feeding into middle and western Tennessee. This trend will then continue into the weekend.
Extended Outlook:
Remember that last “PWAT” image, shown above? Well here it is again as a screenshot to show you that a cold front will be approaching our area this weekend:
With the conjunction of an approaching front and the influence of the tropical low pressure, chances for storms really ramp up Friday through Sunday. If you have outside plans, prepare to move those inside.
