100s are in the forecast for most of this week in North Texas.  Today and tomorrow will actually be the coolest days with highs in the mid to upper 90s.


But the heat really cranks up by Wednesday thru the weekend thanks to an upper level high pressure system that will be establishing itself over the southern Plains.

There is some tropical moisture in Texas, but it will stay just to our south and west.

Here is a look at the features on the weather map to take note of today.

What is left of Tropical Storm Fernand is raining out over the mountains along the Central Mexico Gulf coast.  There is another disturbance over South Texas.  And to our north is the big area of high pressure.  The disturbance (drawn as a red dashed line) will slide across South Texas tonight and then move into West Texas tomorrow.  This will bring very small rain chances to area south and west of DFW tonight and tomorrow.  Rain coverage will be very low in North Texas, but higher out west.

Here is an animation showing the track of that upper level disturbance and the high pressure building overhead by the weekend.

After this small rain chance tomorrow, it will be the upper level high pressure system that wins out and brings the heat.
