According to the National Weather Service, scattered showers and thunderstorms are underway along and north of I-20 in response to shortwave ascent impinging on a 1.8 to 2 inch Precipitable Water axis situated across North Texas.
Increasing clouds will keep high temperatures several degrees lower than previous days. However, parts of Central Texas will still climb as high as 104 this afternoon, and a Heat Advisory is in effect for portions of Central and East Texas. Scattered showers and storms are also possible today mainly along and north of I-20 during the afternoon. Rain chances are 20-40%. Damaging microburst winds will be the main hazard.
Most activity thus far has consisted of light showers, but a couple isolated thunderstorms have also been able to become established. This activity may begin to wind down later this morning with a relative minimum in precipitation around midday.
A second round of perhaps more robust convection is possible with aid from diurnal heating late this afternoon and evening, especially across North Texas into the Ark-La-Tex which may push southward with time along consolidating outflows.
Rain chances will come to an end by Saturday as a ridge of high pressure re-strengthens overhead. Triple digit high temperatures, plentiful sun, and south winds of 10-20 MPH will create elevated fire weather conditions each afternoon this weekend through the middle of next week. Remember to stay hydrated and take frequent breaks in the shade or in air conditioning if your plans bring you outdoors during the heat of the day.
