Clear and already warm at Harry Reid International early Tuesday, with temperatures around 84°F at 5:35 a.m. PDT. The valley is set to bake through the afternoon, with highs near 110°F expected today and again Wednesday, while overnight lows linger in the mid 80s, offering little relief for many residents.
Afternoons: Heat Cranks Up
Highs are expected to climb to about 110°F in the late afternoon Tuesday and Wednesday, with the most punishing hours landing roughly between 4 and 6 p.m. With low humidity and long stretches of sun, heat stress is a real concern for outdoor workers, seniors, and anyone without reliable air conditioning, according to NWS Las Vegas.
Nights: Little Relief
Nighttime cooling will be minimal, with forecast lows hovering in the mid 80s. Tuesday night is expected to bottom out around 86°F, with only slight overnight drops in many neighborhoods. That limited relief raises the chance of heat-related illness for people who sleep without air conditioning or who cannot access cool indoor spaces.
Winds And Fire Risk
Southerly winds will increase later in the week, with afternoon gusts strengthening Thursday and Friday. Some locations could see gusts in the mid 20s to mid 30s mph. The combination of dry air and wind late in the week will bump up fire danger, so avoid using open flames or fireworks during windy afternoons and follow local guidance if flags or watches are issued.
Where To Cool Off
Clark County operates daytime cooling stations and hydration outreach during extreme heat events, and residents can call 2-1-1 or check the county listings to find an open site nearby, including library branches and community centers. If you or someone you know shows signs of heat exhaustion such as heavy sweating, weakness, dizziness, or nausea, move to a cool place and seek medical attention if symptoms worsen.
Plan ahead for outdoor plans, shift labor and athletics to morning or evening hours, hydrate often, and check on neighbors who may not have steady cooling. This space will be updated if any watches or advisories are issued later in the day.
