Sunday Update: Rain Chances

Headline: 

Increasing tropical moisture will bring the  chance for locally heavy rainfall to most of South Central Texas, but  especially the Coastal Plains.

Threats & Impacts: 

Rainfall:  Less than 2 inches west of Highway 281, 1-3  inches for the I35 corridor, and 2-4 inches for the Coastal Plains.  Isolated locations could receive 5-7 inches (mainly in the Coastal  Plains).

Timing and Overview:

While there is a 20% chance for tropical  cyclone development, significant strengthening of the tropical  disturbance is not expected. This disturbance will bring a chance of  decent rainfall to the area beginning in the eastern half today and  spreading to most of South-Central Texas Monday-Wednesday. While  significant flooding is not expected due to dry antecedent conditions  and breaks in activity, minor flooding is possible in areas that pick up  the isolated higher totals. The disturbance is expected to exit the  region by Wednesday, but if it strengthens/slows down, the rainfall  total forecast could increase slightly.  

Confidence:

Moderate
