<p>High pressure is calling the shots, once again, out west. That's going to bring searing heat to parts of California and Arizona, but it's helping do something else: soak Seattle.</p><p>A stubborn area of high pressure is going to sit on top of the West Coast for the remainder of the week. That will help pump more tropical moisture up and over it, focusing it along the Pacific Northwest (above). That will bring rounds of rain, sometimes heavy, to areas surrounding Seattle. Rounds of rain will add up to multiple inches of rainfall, even into the Cascades. Flood watches cover the area until Friday.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/03/Screenshot 2026-03-17 110122-1773766902713.png">The threat of rain will be persistent, soaking many plans for the rest of the week. Notice that most of this is coming down in the liquid form, with very high snow levels. That could help melt additional snow, leading to runoff issues in some of the area creeks and streams.</p><video src="https://media.weathernationtv.com/app/uploads/2026/03/2026-03-17 06-17-49-1773749997320.mp4" controls="true" width="100%"></video>

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

<p>A heatwave is coming to the West. A surge of unusually warm air is spreading across large parts of the United States, bringing temperatures that feel more like late spring than early March. Temperatures will be in the 90s and 100s at times during the next seven days. Daily and all-time March records will be challenged. Many records were already broken in California on Monday with San Francisco hitting 83°.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/03/Screenshot 2026-03-17 083139-1773757914703.png">The heat is only beginning. The peak of the warmth happens mid to late week.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/03/web1-1773742001900.png">Afternoon highs in several locations are expected to climb into the 90s and even 100s, shattering daily temperature records and creating a dramatic contrast from the colder conditions that typically dominate early March. In some areas, temperatures are running 20 to 30 degrees above seasonal averages, leaving residents reaching for short sleeves rather than winter coats.<span style="color: rgb(36, 36, 36)">&nbsp;</span></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/03/web2-1773742052453.png">Heat alerts<strong> </strong>are in effect next week across portions of California and Arizona. Now is the time to get mentally ready for the upcoming heatwave, where records will be challenged. Los Angeles is under an <strong>Extreme Heat Warning.</strong></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/03/web3-1773742080054.png">The all time March record high for Downtown Los Angeles is 99 degrees. Many other locations across California, Nevada, and Arizona are expected to get dangerously close or hit their all time records for March this week.<img src="https://media.weathernationtv.com/app/uploads/2026/03/1-1773455828667.png">The warmth will likely persist for several days across many areas before temperatures gradually trend closer to seasonal averages as the pattern shifts again.<span style="color: rgb(36, 36, 36)">&nbsp;The Climate Prediction Center has a high confidence that temperatures will stay above normal through the end of March.</span></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/03/web4-1773742124182.png"></p><p>More on your Western Regional Forecast can be found :50 past the hour on WeatherNation.</p>

However, getting 2-3 in the span of one week can bring a fair bit of snow to the area. Not to mention, the midwest/northeast has already seen over 3 feet of snow with their last system.

<p style="margin: 0in; margin-bottom: .0001pt;"><span style="font-size: 13.5pt; color: #454545;">Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

The peak is expected around late March into early April (between the 31st and 2nd). Still, the forecast for the peak is generally difficult to make beyond ten days, as blossoms will be impacted by weather conditions. Check back in for updates!</p><h2>What is "peak bloom"?</h2><p>The peak bloom date is defined as the day when 70% of the Yoshino Cherry blossoms are open, one of <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.nps.gov/subjects/cherryblossom/types-of-trees.htm"><strong><u>many types of cherry trees</u></strong></a> in the area.
