PRESCOTT - Less than a week after powerful storms dumped about 2.5 inches of much-needed rain on Prescott, another round of storms could produce another inch of rain.
The National Weather Service expects the main storm to move in tonight and produce the bulk of its precipitation on Friday.
That means rain is likely to dampen another holiday event in Prescott, Friday night's Acker Musical Showcase at downtown businesses.
"I would definitely prepare for wet and windy," said Robert Bohlin, a meteorologist with the National Weather Service office in Flagstaff. "When it starts raining, it's going to rain for a while."
Friday also will be the windiest day, with the possibility of sustained speeds of 20-30 mph and gusts up to 45 mph in Prescott.
Higher elevations will get snow. Prescott sits at the dividing line between rain and snow. Rain, sleet and hail hit Prescott's annual Christmas parade last Saturday.
Showers from this round could continue through Monday, the Weather Service said Wednesday afternoon. In all, Prescott and the rest of Yavapai County could get three-quarters to one inch of rain.
The Weather Service could end up issuing a flood advisory like it did last weekend, Bohlin added.
This storm will be slightly colder than the last one, he said.
The southern fringes of Prescott that sit above 6,000 feet in elevation could get 1-3 inches of snow, Bohlin said.
The second wave of the storm system should arrive Saturday night and Sunday and be even colder, but it might not produce much precipitation, the Weather Service said. Snow levels could drop to 4,500 feet but the chance for precipitation is only 20-30 percent, compared to 70 percent Friday and 60 percent Friday night.
Areas to the north have a better chance for snow. The Weather Service is forecasting 3-6 inches of snow in Flagstaff and Williams, 1-4 inches near the North Rim, 3-9 inches in Fredonia and 2-8 inches in Show Low and Pinetop.
