More Heat this Week

Yesterday was the hottest day of the year with 95°, but today felt hotter.  The humidity really has an impact.  The high reached 94°, but the heat index was near 100°…Ugh!

An upper level ridge of high pressure is the reason for the excessive heat and humidity. The humid Gulf air is being brought in as the wind rotates around that summer time feature, the Bermuda High.


Tomorrow will bring a greater chance of rain and thunderstorms. They will be spotty, but more widespread than yesterday.

By Friday a weak cold front will approach Middle Tennessee . With a deep layer of moisture in place across the midstate, rain and thunderstorms is very likely.  Thunderstorms are also possible and some of them could be strong. The Storm Prediction Center has put the northern part of Middle Tennessee in a “Marginal Risk” zone (1 on a 1-5 scale).


2 inches of rain is possible and this could trigger some localized flooding.  Rain will linger into Saturday.  Right now it does look like it will be drier in the later part of the day Saturday. Sunday will be drier, only a few isolated thunderstorms are possible Sunday. So it looks like the weather will cooperate for some fun in the sun.


I’ll have an update on Channel 4 News at 10pm.
