 They're used to shrugging off the heat in Las Vegas. Residents there are now eyeing the thermometer as the desert cities on track today to set a record for the most consecutive days over 115 degrees Fahrenheit amid a lingering hot spell that continues to scorch much of the country into the weekend. On Tuesday, Las Vegas flirted again with an all-time high temperature of 120. That was reached on Sunday, but it settled for a new daily mark of 119. The searing heat wave gripping large areas of the country also led to record daily highs in Oregon.
