.Forecast Summary...Clouds will be on the increase tonight as a weak area of low pressure approaches. Tomorrow will be mostly cloudy and cooler as the low passes through our area. There will also be isolated showers but, any precipitation will be light. The weekend will be dry and a little warmer with high pressure over the region. Looking ahead to next week, winter weather will make its return as several systems will pass through our area. They will not be very strong but provide showers and cooler temperatures. Snow is possible for the mesas and mountains. Looking beyond the forecast period, a stronger storm could arrive for the holiday weekend.
