Moisture Lingers Across The West

Updated By WeatherBug Meteorologist, Rob Miller
After several days of rain and mountain snow inundating the Western U.S., showers will linger this morning before drier weather starts to return this afternoon.
An area of low pressure parked along the Washington beaches will fizzle out after losing its once vaunted eastern Pacific moisture connection. This will mean locally heavy rainfall will shrink in aerial coverage along parts of the southern and northern California beaches, as well as near or west of Interstate 5 in Oregon and Washington this morning.
One half-inch to locally more than an inch of additional rainfall will likely exacerbate poor drainage urban, stream, river, and creek flooding. Flood Watches remain in effect across California from the Central Valley to the U.S.-Mexico border. Sacramento, Modesto, San Francisco, San Jose, Monterey, Fresno, Los Angeles, Anaheim, and San Diego, Calif., are included. If you approach a roadway covered in water, it is best to “Turn Around, Don’t Drown!”
The storm’s upper-level disturbance, however, will cruise into the Four Corners, leading to accumulating wet snow throughout today. The highest peaks, above 7,000 to 9,000 feet across Utah’s Wasatch Range and parts of the northern Colorado and southern Wyoming Rocky Front Range, will end up digging out from 6 to 12 inches of snow. Twelve to 18-inch totals cannot be ruled out along the west-facing ridge tops, especially in the Sierra Madre and Snowy Range in Wyoming.
Meanwhile, additional snowfall accumulation of 2 to 4 inches or locally higher will be commonplace along the Sierra Nevada.
Winter Weather Advisories and Winter Storm Warnings remain in effect across the Sierra Nevada, as well as the San Bernardino and Riverside County mountains in California. These advisories and warnings are also found over the higher terrain in southern Nevada to Utah’s Wasatch Range and parts of northern Colorado and southern Wyoming’s Rocky Front Range. Travel will become difficult, especially across Interstate 80 in the Wasatch Range. Make sure to check ahead about chain requirements in travel cannot be avoided.
A much needed change of pace in the weather pattern will arrive across the West on Thursday and Friday beneath large high pressure at the surface and aloft. Dry, seasonably mild weather with plentiful sunshine will lead to diminishing stream, river, and creek flooding.
