A large, deep trough of low pressure covers most of the western US. To the east, deep moisture persists over Texas and the eastern US. The low pressure is pushing a slow moving cold front across west Texas. As the front sags southward, heavy rain and thunderstorms are likely across the southern Edwards Plateau and Hill Country. Already areas west of Cotulla have seen as much as 10 inches of rain in a few isolated spots.
Lighter, but still significant, rain amounts are expected across the San Antonio metro region through Friday. Some areas might see an additional 3-4 inches of rain. Clouds and showers will moderate temperatures with afternoon highs in the low 80s and lows near 70.
