Upper-level high pressure remains in place across Texas. That will keep us warm and dry through the weekend. A low pressure system over the southwestern states is blocked from moving eastward. High temperatures will be in the mid- to high 80s and lows in the mid- to high 60s through Sunday. The high will begin to move to the northeast by Memorial Day and allow the low to approach from the west. There will be a slight chance of showers and thunderstorms Monday and Tuesday.
