Unsettled and wet weather will continue today through Tuesday. A lead disturbance made its way across AZ on Sunday bringing widespread lower desert light rain and high elevation snow. This system has since exited east into NM, but a second more potent disturbance will arrive later today bringing greater precipitation totals spread across multiple waves of showers/storms. The main window for this activity will begin this evening and continue through Tuesday morning with additional isolated showers/rain possible into early Wednesday morning (more details on this below). Otherwise, plan on daily highs limited to the low 60s with overnight lows in the 50s due to cloudy and humid conditions. Moving ahead, the second system will exit the region into Wednesday with a warming and drying trend on the horizon...
