Upcoming Weather System Overview
San Antonio is preparing for a significant weather change as a Pacific storm system approaches Texas, expected to bring rain and thunderstorms starting Wednesday. The system, currently located in California, will take two to three days to reach West Texas before moving into the San Antonio area. Initial rain chances are forecasted for Wednesday, primarily affecting the western regions, with a more substantial impact anticipated on Thursday.
Rainfall Predictions and Flood Risks
The National Weather Service has issued a level 1 of 4 outlook for localized flooding in the western half of San Antonio, escalating to a level 2 of 4 on Thursday. Rainfall totals could vary widely, with some areas experiencing between 0.75 inches to over 3 inches, particularly in the western third of the region where storms may train over the same areas. The IBM GRAF model suggests the potential for heavy rainfall exceeding 5 inches, although this remains an outlier scenario.
