LAS VEGAS — Mostly sunny in Las Vegas today, with temperatures climbing to the upper 80s and low 90s this afternoon as humidity lingers. Northeast breezes are light at 5-10 mph. Scattered thundershowers in Arizona and Utah delivered passing rain to Mesquite this morning, but Southern Nevada only carries a 10% rain chance today. Readings drop to the 80s this evening with low and mid 70s later tonight under a mainly clear sky.
Tropical Storm Harold sent heavy rain and gusty winds across South Texas today, and high pressure over the Central Plains will steer that moisture across northern Mexico into the Desert Southwest on Wednesday and Thursday. This gives Las Vegas a 30% and 40% chance of pop-up thunderstorms, respectively. Highs reach the low-to-mid 90s those days with a mix of clouds and sun and continued humidity.
Friday trends dry (only a 10% chance) as we return to the mid 90s with lingering mugginess. Sunshine and the first 100° weather in over a week are here Saturday as a bit of humidity sticks around. We'll dry out Sunday through early next week with highs more typical for late August (between 100° and 105°). Lows at night will be in the 70s this week but climb near 80° Friday night and beyond.
