Even NAZ Today Meteorologist Lee Born gets surprised by the weather once in awhile. That happened Thursday when a few thunderstorms with light rain moved through Flagstaff. But he's not expecting a repeat of that on Friday. It will be sunny and warm through the weekend with breezes gradually picking up into Sunday. Highs in around 70. Things will change on Monday, when these above average high temperatures will dip to the mid-50s, with the potential for strong thunderstorms.
