We have a much cooler day in the Las Vegas Valley today after a frontal passage last night. High winds swept through the area yesterday afternoon into the evening with high wind warnings and wind gusts in excess of 50 mph. Much calmer today with our high expected to be only in the low to mid 70s. As of 12:45 PDT the temperature here is 72 deg and a dew point of 25. It appears that most of the week will have high temps in the mid to upper 70s.
