A weak spring storm is moving onshore over California today. Areas of scattered showers and thunderstorms are being experienced in many areas of the Southwest today, as well as gusty winds in portions of the mountains and deserts. Higher elevations have experienced some snow.

For the Coachella Valley, as of 430p, currently a strengthening front is draped northeast to southwest across the valley, from near Las Vegas, curving south southwest across the deserts to near Indio, and southward to near Borrego Springs and south into Baja California.

The front is currently stalling, and strengthening, with large thunderstorms forming just ahead of it, moving through Imperial County and eastern Riverside County. An impressive shield of cirrus anvil cloud tops are visible to the east, as a result of this rapidly developing line of thunderstorms. The line is temporarily stalled, but will begin moving slowly east towards the Western Arizona deserts the next several hours. Anyone traveling I-8 to Tuscon or I-10 to Phoenix tonight may experience strong winds and isolated heavy downpours or even hail.

Here is a current radar image, showing the system to our east.

Behind the cold front, an unstable airmass is producing scattered locally heavy showers and thunderstorms across the rest of California. The nearest storm cell, as of 430p, is a stray storm located in the mountains west of Palm Springs, between Banning and Hemet, moving slowly northeast and weakening. If this cell holds together, it is possible a brief shower or thunderstorm could affect the Palm Springs or Desert Hot Springs area around 5-6pm. Other cells have formed in the high deserts near Lancaster, as well as heavy rain and hail in the mountains of Ventura and Los Angeles counties. The Central Valley from Bakersfield to Fresno is experiencing large areas of heavy rain as well. Here is a radar image from Intellicast around 440p to our north and west.

The rainfall to our north is expected to diminish after sunset, becoming much more scattered as the light of day diminishes the surface heating, which is fueling the pop up storms across much of the state today.

Partly cloudy weather will return Thursday, with sunnier skies Friday. By Saturday, another weak system could bring very scattered showers, as well as another system around Monday or Tuesday.

High temps will likely remain depressed into the 70's or low 80's for most of the next 4-5 days, with gusty winds at times. Enjoy the "cool down" while it lasts!
