A rainy and stormy night occurred on Sunday in the western part of the viewing area. This was caused by a combination of a frontal boundary to the north and moisture from the south. The resulting rain led to significant totals in some areas.

Starr County received the most rain, with totals reaching as high as 4 inches. Nearby Hidalgo County also saw substantial rainfall, with totals between 2-3 inches. Further details about the storm and its effects are available from ValleyCentral.
