Following days of scorching heat in the southwestern United States, chilly air and wet weather will push inland through early week.
The cool and damp conditions will blanket the region after a hot end to the week in the Desert Southwest.
“A storm will bring clouds and rainfall to Southern California, southern Nevada and Arizona," AccuWeather Senior Meteorologist Mike LeSeney said.
The rain forced the postponement of the Los Angeles Dodgers versus the San Diego Padres baseball game at Petco Park on Sunday afternoon. This marks the first postponement in San Diego since July 19, 2015, according to a local media outlet. Before 2015, the last rainout was in 2006.
The announce that today's game vs. Dodgers has been postponed and will be rescheduled for Sep. 2 at 12:40pm: 
The rain could be heavy enough for localized flooding to occur, especially along the Southern California coast into Sunday evening.
“The setup is ripe for isolated heavy, gusty thunderstorms to develop elsewhere across the Desert Southwest,” LeSeney said.
Any storms that do fire could pack a punch with very strong winds, small hail and heavy rain.

The cooler and cloudier weather will decrease the fire threat across Arizona and Nevada.
Combined with the recently hot and dry weather, the threat for quick-spreading fires will shift to New Mexico into Sunday night.

Although temperatures in the 90s F were common across southern Nevada, Southern California, Arizona and New Mexico on Saturday, the fresh, cooler air mass pushing through the Southwest will contain this heat to Texas on Sunday.
While temperatures in Las Vegas hit 100 F on Friday and 90 on Saturday, the mercury will peak in only the mid-60s on Sunday.
Temperatures above the century-mark in the deserts of California and Arizona will be replaced with highs in the 60s and 70s, including in Palm Springs, California, and Phoenix.
Cool West Coast

Over the mountains of Southern California, the air will be cold enough for snow to fall and accumulate.
Motorists should turn on their headlights and slow down as visibility decreases in any storms.
The threat for locally damaging storms will shift eastward to the Colorado Front Range on Monday and Tuesday.
