The remnants of Tropical Cyclone Rachel and a Pacific low pressure system will combine to produce windy conditions across much of the area through late this afternoon. Wind gusts upwards of 30-55 mph are expected. A Wind Advisory has been issued for much of the area.
As the remnants of Tropical Cyclone Rachel move northward into southern Nevada later today, a Marginal Risk for severe storms will continue through this afternoon. The Storm Prediction Center has categorized the probability of severe winds between a 5-14% and chances for tornadoes between a 2-4% across portions of the lower deserts into the Arizona high terrain.
A deep low pressure system over the west coast will push inland and through the area Monday and Tuesday, bringing additional chances for showers and storms, mainly across south-central AZ. Rainfall amounts for the most part should remain light with most areas seeing less than 0.25". With the passage of the system, temperatures will be well-below normal.
