The National Weather Service predicts that Las Vegas will not break another heat record today, with the daytime high forecast at 93 degrees, five degrees less than Wednesday's record-breaking 98. This is expected to be the first time the city has seen eight consecutive days of record-setting heat, a streak the valley has never seen. The National Weather Services expects temperatures to remain in the low 90s for Friday and the weekend, with more records expected. The extreme temperatures are expected to continue to break across the Southwest.
