A pattern change will bring cooler temperatures to the West as May begins, but not before temperatures surge to record warmth.
The jet stream will ride well into Canada into this weekend, creating widespread warming that could tie or set more than a dozen daily record highs.
Temperatures will drop from near-record highs from the inland valleys of the Los Angeles Basin to the northern Rockies, including Casper, Wyoming, Billings, Montana, and Boise, Idaho.
Warm air will last one more morning. Lows Saturday morning will be in the 40s and 50s across the Northwest and Great Basin and in the 60s and 70s in the desert Southwest into the Southern California metro areas.
Some relief is expected as May begins and a new cold front arrives.
A few showers will arrive Saturday in the Pacific Northwest, which will cool temperatures as the front arrives.
Temperatures will cool further in the Rockies by about 10 to 15 degrees as the boundary droops southward this weekend.
As the next week begins, temperatures in large sections of the northern and central Rockies will drop below average. Highs will only reach the 50s and 60s in the northern Rockies, Northern Plains and Northwest. Some higher-elevation spots, including Denver and Cheyenne, will be in the 30s and 40s on Monday.
Forecast HighsThis front will bring some much-needed rain and even some late-season snow to Colorado and Wyoming as it drops south.
A foot of snow could fall in the highest peaks of the Rockies, which remain in the midst of a long-term severe drought.
