Numerous showers and thunderstorms will continue across the Las Vegas area through late afternoon Sunday before tapering off this evening, the National Weather Service in Las Vegas said in its 12:27 p.m. forecast discussion. Brief heavy rain and lightning are possible until then. Drivers should allow extra time, and anyone outdoors should head inside when thunder is heard.

Rain fell overnight across the region. The weather service put totals at roughly a quarter inch to three-quarters of an inch across the eastern Mojave Desert, including Las Vegas. Totals of a tenth of an inch or less were reported across the western Mojave Desert and the valleys of Inyo County, California.

At 11:30 p.m. Saturday, the weather service said it was raining at its office and at Harry Reid International Airport, which had recorded 0.04 inches so far that night. It said another 0.19 inches before 1 a.m. Sunday, which is midnight standard time, would tie the all-time wettest October on record for Las Vegas.

The heaviest rain of the storm system fell farther east, over eastern Lincoln and Mohave counties, where widespread totals of 1.5 to 4 inches were observed. Heavy rain over the Big Sandy watershed in northwestern Arizona pushed Burro Creek and the Big Sandy to near-record flows, which were continuing Sunday afternoon. The main band of steady rain has since shifted east and is now centered over eastern Arizona.

Behind it, instability ahead of the trough is feeding thunderstorms over the Death Valley and Amargosa Valley areas. Those storms are expected to keep developing toward the Spring Mountains through the afternoon, with localized heavy downpours. A few storms will also form over northwest Arizona. All of this activity should fade through the evening as daytime heating is lost and the trough moves east.

At Harry Reid, the best chances for showers, and possibly an isolated thunderstorm, come between about 10 a.m. and noon and again between about 2 p.m. and 5 p.m. Those periods could briefly lower cloud ceilings and visibility. Rain chances should end between roughly 5 p.m. and 6 p.m., and skies are expected to improve markedly this evening. Breezy southwest winds with gusts of 15 to 25 knots are expected this afternoon. There is about a 40 percent chance of northwest winds with similar gusts arriving after about 3 p.m.

Monday looks dry, with breezy northwest winds in the morning that weaken and turn northeast. Temperatures will start the week slightly below normal and climb slightly above normal by next weekend. Patchy fog is possible in the cooler valleys over the next few mornings, so drivers should plan for reduced visibility early in the day.
