Print ArticleSTATE COLLEGE, Pa. – AccuWeather.com reports impacts from the first in a pair of Pacific storms will be confined to the Northwest today. Virtually all of the West will be affected by the second, more powerful storm Friday into the weekend, bringing an end to the West's recent dry and sizzling conditions.
The change will first be noticed across the Northwest today as a cold front sweeps through. Temperatures will fail to reach Wednesday's warm highs by roughly 10 degrees as periods of rain fall.
Today's storm will pale in comparison to the system on its heels. The more potent storm is forecast to slam onshore late Friday. Rain and wind will increase through Friday from southwestern British Columbia to northern California. Winds capable of downing trees and power lines will blast the coastline and Cascades Friday afternoon into Saturday morning.
The rain and wind will spread southeastward across the rest of the West Friday night into Saturday. A period of rain will even reach Los Angeles and San Diego. For most of California, the storm will be the first significant rain event since the spring.
Flash flooding and debris flows could quickly ensue over areas recently charred by wildfires. The threat will be greatest over this area since that is where the storm's heaviest rain will fall.
The colder air following the storm will be another dramatically changing aspect to the weather pattern. Between 15 to 20 degrees will be shaved off high temperatures from today to Saturday across the northern Rockies and Southwest.
After nearing the 90-degree mark today, temperatures will fail to reach the 70s on Saturday in Downtown Los Angeles. Today is not even the hottest day of the week. The record high of 100 degrees from 1991 was tied on Wednesday.
