LAS VEGAS — Expect southwest gusts of 30 mph again today as highs reach 107° with continued sunshine. Lingering 25 mph gusts Thursday as afternoon readings hit 109°. As we see it now, a big ridge of high pressure centered over Southern Nevada will send highs to 112° Friday, 115° Saturday, 116° Sunday, and 115° Monday. Highs linger at 112° next Tuesday, and 110° next Wednesday and Thursday. Lows at night will climb from the mid 80s this week to near 90° Friday night, and remain that warm through the weekend into early next week. Humidity will be noticeable early next week as the heat lingers, although right now we don't see much in the way of monsoon rain chances reaching Southern Nevada.

To beat the heat in the summer, shift outdoor activities before 9:00 a.m. or after 7:00 p.m. to avoid the direct sun and warmest temperatures. When outside, remember to drink plenty of water, seek shade, and wear lightweight, light-colored clothing with a hat and sunscreen. Avoid excess caffeine and alcohol. Watch those vulnerable to intense heat, including young kids, the elderly, and people with health issues that make them prone to heat illness. Keep an eye on pets and make sure they have fresh water. The UV index remains very high to extreme, so remember to use sunscreen and keep a hat handy; a sunburn can happen in just 10-15 minutes this time of year. Pollen levels remain in the medium category this week with grass, ragweed, and chenopods the predominant allergens.
