Happy tax-free weekend.

It'll be a great Saturday to head into the air-conditioned stores – highs will be flirting near the triple digits with heat index up to 108 degrees. A Heat Advisory is in effect for most of North Texas until about 7 p.m. 

The dry and hot weather this week was caused by a ridge of high pressure dominating in the upper levels of the atmosphere. This ridge is expected to shift to the west over the next few days, which will allow for a change in the weather pattern.

Temperatures will be on the decline, eventually dipping below average through mid-week next week. Pop-up showers and storms will also be possible.

As of now, no severe weather is expected. Stay tuned.
