It’s been bone dry across the Southwest this winter, allowing for the development of a moderate to severe drought across a significant area. Now even though rain is in the forecast this week, it will be very light and will therefore not ease the drought conditions.

On Tuesday, an upper-level low off the coast will steer moisture into portions of the Southwest. Therefore, very spotty light to moderate showers are possible across Southern California, southern Nevada, and Arizona while snow showers are expected in portions of Utah and the Sierra Nevada Mountains.

Now on Wednesday, the precipitation will become more widespread as more moisture is funneled into the region. The hotspot of the activity will be focused in Arizona where rain will develop across most of the state by the end of the day. There will also be snow in the higher elevations of the state. Those rain showers will also stream into southern parts of Utah, Nevada, and California, including Las Vegas and Los Angeles.

On Thursday, a few lingering rain and snow showers can be expected across portions of Utah, Arizona, and New Mexico while the rest of the region dries out. It’s not until Friday when all of the Southwest U.S. will experience a return to the quiet and sunny weather.

Only up to half an inch of rainfall is forecast for most locations expected to receive any rain. In the higher elevations of Arizona and Utah, up to an inch of rain is forecast or up to two feet in some of the peaks.
