An unusual weather pattern will bring several days of much above-normal temperatures to California and much of the Southwest. Dozens of new daily high temperatures records are likely to occur by early to mid-week, and some locations could reach all-time high temperatures for the month of March.
A shortwave trough is expected to develop this weekend that will pass quickly through the Great Basin Saturday into early Sunday. Northwest winds 20 to 30 mph with gusts up to 45 mph are expected in the Mojave Slopes during this time frame, and as such a Wind Advisory has been issued.
