Scattered showers and thunderstorms are possible into the evening hours before decreasing as a disturbance moves through the region. Over eastern districts, a few strong to severe thunderstorms are possible with the main threats being strong and erratic winds, hail, and heavy rain. Thursday into the weekend, warmer and drier conditions look to return, but cannot rule out isolated showers and thunderstorms each day. High temperatures will trend towards the 80s and 90s, with afternoon RH down in the 20s and 30s percent, highest over eastern districts. Thermal belt activity near the mountains will lead to moderate to poor RH recoveries at times in the mid slopes.
