Additional showers and storms are expected this afternoon. Rainfall today will generally stay under an inch, though isolated higher amounts are possible. :warning: A Flood Watch remains in effect through this evening.

Weekend Outlook: Rain and storm activity will focus primarily along and south of I-10 through the weekend. The combination of a weak and slow-moving frontal boundary and a developing coastal trough along the Texas coast will create prime conditions for repeated heavy rainfall. Additional rainfall of 2 to 4 inches is expected through Monday, with localized higher amounts possible. If the front shifts northward, the area of heaviest rain will move further inland.

Looking ahead: Rain chances diminish after Monday in the wake of the frontal boundary. Highs will generally remain in the 80s.
