The exception is over parts of the Edwards Plateau and Rio Grande Plains where little or no rainfall and partly sunny skies are expected. Highs will be in the 50s over most areas, but a few 60 degree readings could be found along the Rio Grande.
Cool and mostly damp continue for most areas through daytime Friday. Then expect rain to end and clouds to decrease by Saturday. Saturday will be slightly warmer than normal, but a cold front Sunday will make temperatures Monday and Tuesday below normal. Mid to late next week weather looks warmer and continued dry.
Chances lean slightly towards above normal precipitation for the Coastal Plains this December, with equal chances of above, near, and below normal precipitation elsewhere in South-Central Texas. Chances lean towards warmer than normal conditions across the region.
Beneficial rainfall may improve drought conditions east of I-35. Better chances for above-normal rainfall for the Coastal Plains could lead to improving drought conditions for the region this December. Extreme drought conditions continue in the San Antonio area. Drought conditions in the San Antonio area expanded slightly in November and are forecast to persist in December.
