The cold, upper-level trough that covers much of the Southwest today will move east the next several days with a building ridge behind it. This will cause a major warming trend for much of California, Nevada and Arizona through the end of the weekend and in the deserts through the weekend. Temperatures the last two days in California have been running 10 or more degrees below normal. In the lower deserts of California and Arizona, temperatures have been 5-8 degrees below normal. However, by Friday, in the lower deserts, temperatures are going to be 5-7 degrees above normal, and over the weekend will be 10-15 degrees above normal. For the tens of thousands that will again head to Empire Polo Club for the second weekend of the Coachella Music Festival, temperatures are likely to be in the middle to upper 90s this weekend. Warming will be slower in Arizona, but it's likely to be above 90 in the warmest deserts by Saturday and in many more places Sunday.
This storm will endanger life and property both on the seas and over land in a large area.
A huge storm is expected it impact much of the Bering Sea beginning Friday night
This will be the first significant statewide rain and snow event of the season.
