13 First Alert Weather Forecast | Monday morning, August 8, 2022

LAS VEGAS — Partly to mostly cloudy and warm this afternoon (upper 90s) with a 30% chance of a pop-up storm in the valley. The threat of locally heavy rain, storm-related winds, and lightning is in the forecast each day this week. We'll drop from the 90s to the 80s tonight, and the chance of rain after dark is fairly low at 10%. Tuesday and Wednesday see increased humidity and storm chances climb to 40% each afternoon. Thursday and Friday could also be unsettled, with storm chances in the valley remaining at 40% as humidity stays stifling. Highs will be limited to the mid-to-upper 90s all week due to the mugginess, the increased clouds, and the chance for afternoon downpours. Overnight lows will be in the upper 70s and low 80s during this stretch.
