6/28 – Trey Tonnessen’s “Variables” Friday Afternoon Forecast

Meteorologist Trey Tonnessen

The changing upper levels of our atmosphere do eventually force the shear axis out of the area by Sunday as it consolidates just to the west of the area near the Texas-Oklahoma border. It then builds east and eventually stretches along the Interstate 20 corridor for the middle and end of next week. Moisture levels remain rather high, with precipitable water values remaining near or above 2 inches and surface dew points generally in the mid and upper 70s. That will generally mean daily thunderstorm development during the diurnally favored cycle of during the afternoon over land, and late night over marine areas. With daytime high temperatures continuing to be in the mid 90s in much of the area, Heat Advisories will probably be necessary Sunday and for several days beyond, at least.
