More Needed Moisture Heading to West Coast

27 May 2020, 8:06 am

A trough of low pressure along the West Coast this weekend and into next week could bring more needed moisture to the West Coast.

The Climate Prediction Center (CPC) has put much of the western third of the U.S., and specifically the Four Corners states of Arizona, New Mexico, Colorado and Utah it its wetter-than-average zone for this weekend and into next week. That’s part of an overall potentially strong signal that needed moisture could be in store for the West Coast.

Here’s a look at the CPC’s 6-10 and 8-14 day outlooks, which cover this weekend and next week:


A deep, persistent trough of low pressure looks to anchor over the West Coast starting this weekend. That’ll draw in an upper-level low pressure center by Saturday, bringing rain for places like Portland, Oregon and Seattle, Washington and down into northern California.

Eventually, that same storm system will gradually spin inland, bringing daily afternoon shower and thunderstorm chances to the Four Corners and California and Nevada. A cooler pattern will also ensue, bringing some higher elevation snow chances as well.

This is typically the driest time of the year for the Southwest. Rain chances are fairly rare in late May and early June in states like Nevada, Arizona and southeastern California.

Because this rain is coming at the end of May and into early June, it’s coming at the tail end of much of the West’s wet season. By late spring and into the beginning of summer, the West’s pronounced dry season takes over, stifling most moisture chances.

Fortunately, however, the West could be turning for a soggier turn; and that’s a good thing.  Drought conditions have been very persistent so far this year.

Chris doesn't remember a time when that he didn't love the weather. When he was five years old, he wrote his first words, "Partly cloudy", in Ms. Benn's kindergarten class. According to Chris, it's been a love affair ever since, from teaching himself how to read forecast models at age 12, to landing at WeatherNation. Growing up in Greenwich, Connecticut, he started to go after his lifelong drea... Load Morem of becoming a meteorologist by predicting whether or not there would be snow days - turning him into Greenwich High School's "defacto weatherman". He turned that snow day-predicting website into a front page story a local newspaper, which in turn earned him a look at WABC-TV in New York, where Chris did the weather live on-air at the age of 16. He attended Boston University, where he continued being a "weather nerd", performing weather updates on the campus radio and TV stations, and doing the daily forecasts for the student newspaper. Following his studies at BU, Chris worked at Mile High Sports and ESPN Denver for four years while pursuing his certification in Broadcast Meteorology from Mississippi State University. Chris is a huge sports fan, rooting for the Rockies, Nuggets, Broncos, Avalanche and UConn. He frequently find links between sports and weather, including an investigative analysis he did in 2013, finding trends between Peyton Manning's play and game time temperature (he doesn't like the cold). Chris also enjoys running, playing any sport, socializing and periodically overeating at all-you-can-eat buffets.
