Upper Level High Bringing Hot Temperatures This Week

Posted:

A hot upper level high will be stretching from the east coast to the Tennessee and Ohio Valleys most of this week.

Upper levels highs have sinking air underneath them which compresses and heats up, just the opposite of rising air which expands and cools.

This will push temperatures to the mid 90s in Middle Tennessee, and when combining the humidity, the heat index will be 100° or above by mid week.

This sinking air will only allow isolated t'showers to develop most of this week.

By the weekend, the high should break down allowing a front to drift into Middle Tennessee, bringing a much bigger chance for t'shower activity and slightly lower temperatures.
