Forecast discussion:

The precipitation this week is associated with a strong low pressure system that is expected to move in from the central Pacific to near the central California coast by Tuesday morning and remain there through Wednesday morning. This system will spread strong, moist southwesterlies across Arizona. Precipitation amounts will be highly dependent on location relative to terrain, with heaviest amounts on the upwind (southwest) side and lighter amounts on the downwind (east) side. The attached figure of forecast precipitation amounts shows locations in the Bradshaws receiving 1.5-2.5 inches of precipitation, while regions to the east, such as Chino Valley, Prescott Valley and Dewey-Humboldt will receive around 0.5-1.0 inches. Precipitation amounts on this map are liquid water equivalent (LWE), meaning the amount in the rain gauge if it all falls as rain. According to the map, Snowbowl, where all the precipitation will fall as snow, should get about 2 inches of LWE, which would translate to about 20 inches of new snow. As a rule of thumb, snowfall amounts are approximated as 10 times LWE, assuming it all falls as snow. Time to hit the slopes!

Elevated river flows will occur Tuesday and Wednesday.
