Significant Precipitation In The Northwest


November is closing out here in southeast Arizona much as did October - a single, light precipitation event each month. However, very significant precipitation is expected over much of the Northwest as several impulses associated with the large, complex cyclone over the northeast Pacific (above is water vapor image this afternoon - 29 November 2012) come ashore and interact with the mountains. Rain amounts forecast by the models are prodigious, with some areas forecast to receive 5 to over 10 inches of water equivalent precipitation through the weekend. Current weather watches issued by the NWS offices in the West are indicated below.
