SMALL RAIN CHANCE
No large scale rain is expected, but a few airmass, pop-up showers are possible each afternoon through Monday. The timing is mainly between 4pm and 9pm. Sunday may present a slightly better shot at rainfall, mainly for those east of I-35.
TROPICS: DUSTY AND DRY
The Atlantic remains very quiet, with hardly any tropical activity. Wind shear and a significant plume of dust should keep it that way through mid-August. August is a month in which tropical activity usually picks up, however, this season is expected to be below-average.
