A chilly storm will deliver rain and hail-producing thunderstorms to parts of the West Coast today. Ahead of the storm, gusty and warm winds will blow over the Four Corners region.
Today will definitely not feel like late May across much of the West Coast. Temperatures will be held 5 to 15 degrees below highs that are typical for this time of year.
As much as 20 degrees will separate today's actual and typical highs in California's Central Valley, including Sacramento.
The storm responsible for today's chill will also trigger thunderstorms from western Oregon to central California. The stage is set for some of these thunderstorms to drop small hail.
Enough cold air is in place that snowfall is the main story across the Sierra. Snow levels will be down to 4,500 feet this morning, then again tonight.
The snow will accumulate 3 to 6 inches, with locally higher amounts, in the northern and central Sierra. This includes Interstate 80's Donner Pass. Motorists should prepare for slick conditions, mainly this morning and again tonight.
Occasional downpours will cause travel to slow on Interstates 84 and 90.
The rain is expected to rotate westward across northern Washington tonight, spreading over Seattle in the process. The rain will keep western Washington wet into Friday.
Ahead of the storm, warm air will funnel across southeastern California and the Four Corners region today.
Temperatures will flirt with the century mark in the Arizona deserts, making Phoenix one of the hottest places in the nation. Hartford, Conn., had the rare opportunity of holding that distinction on Wednesday.
Winds gusting up to around 45 mph will usher in today's warmth from southeastern California to Wyoming. Winds of that magnitude will heighten the fire danger and could create problems for high-profile vehicles.
High pressure and drier weather will return to the West Coast on Saturday, the start of the Memorial Day holiday weekend.
As the high moves inland, a round of gusty Sundowner and Santa Ana winds could return to Southern California Friday night into Saturday morning.
