A series of mid to upper level disturbances and above normal moisture will contribute to daily rain and thunderstorm chances across much of South Texas.

Rain chances will generally be low to at times medium (20-45%) starting Monday and continuing through the end of the week.

The main headlines, however, continue to be the very warm conditions for this Memorial Day weekend. The HeatRisk will be at Moderate to Extreme levels Sunday and Monday afternoons, and at Moderate to Major Tuesday and Wednesday before decreasing late week. Heat indices will range around 110-114 Sunday and Monday which may prompt Heat Advisories, particularly across the western Coastal Plains and Brush Country. Rain chances and cloud coverage will then limit heat index values to around 105-110 the rest of the week.

**If planning outdoor activities this Holiday weekend, closely monitor the weather conditions and prepare to adjust plans to accommodate frequent breaks to avoid heat-related illnesses. Always, practice heat safety: drink plenty of water, wear lightweight, loose- fitting and light-colored clothing, and apply sunscreen. Never leave anyone in a vehicle unattended and don't forget to check the backseat!
