LAS VEGAS — A round of spotty storms is possible in Las Vegas this afternoon (20% chance in any one spot) as downpours with lightning drift east off the mountains. Apart from any storms, we'll see highs in the mid 90s with humidity and southwest gusts to 20 mph. This evening the sky will clear and we'll drop through the 80s, with overnight lows dropping to the low 70s.
Wake-up temperatures in the low and mid 70s set the stage for afternoon highs in the mid 90s for the rest of the week. Humidity will taper the next few days, so sunshine will be abundant from late week through the weekend into early next week. Steady temperatures in the 70s early and 90s later are expected for the next seven days, which is pretty typical for mid-September.
