The subtropical ridge remains over the region into the weekend, shifting further east early next week though South Central Texas will still remain under its influence. Dry conditions with daily high temperatures in the 90s are expected to persist under this pattern. Decent mixing each afternoon will help keep heat indices below Heat Advisory criteria, though values will likely be in the triple digits for many each afternoon keeping minor to moderate heat risk over the area. Breezy wind each afternoon and evening subsides slightly overnight.
