.Forecast Summary...Clouds will be on the decrease tonight as a weak area of low pressure moves away. The weekend will be dry and a little warmer with high pressure over the region. Looking ahead to next week, more typical winter weather will make its return as several systems will pass through our area. They will not be very strong but provide showers, gusty winds and cooler temperatures. Snow is possible for the mesas and mountains mid-week. Looking just beyond the forecast period, a stronger storm could arrive for the holiday weekend.
