Heat advisory for southern North Texas, storm chances for northern region

NORTH TEXAS (CBSNewsTexas.com) - A heat advisory is now in effect from Sunday at 1:00 p.m. to Monday at 9:00 p.m. for the southern portion of North Texas.

The DFW Airport received 0.12" of rain, the first measurable rain this month and the most in over two weeks. 

Rain chances are in the forecast for a couple more days, including small chances Sunday night and early Monday but better chances arrive Tuesday morning. Storms from the Panhandle will take the overnight highway to North Texas, arriving just around morning commute time.  

On Monday and Tuesday, we will have high pressure to the west, driving the high plains storms southeast toward us. They weaken overnight, meaning rain chances will be spotty and severe chances stay low.  

By Wednesday that dome of hot air will slide into North Texas; rain chances disappear and temperatures go up.

More heat advisories are expected later in the week as we start another run of 100-degree days.

Most of the long rain models show a dome of hot high-pressure building over the Central Plains starting mid-July. There's expected to be a long run of hot and dry weather. The temperature outlook for next week shows the heat building in from the southwest and one last round of rain and storms are in the mid and northern plains.

By mid-week, there won't be much rain, but there will be plenty of heat.  

There is a recent development in the extended forecast that suggests a bit of a break in the heat for Saturday through Monday. It includes modest rain chances by Sunday if there is a northwest flow that delivers storms overnight.
