November 2nd, 2024: Valley Rain and Mountain Snow on Sunday
Synopsis A mid latitude trough is expected to continue to dig southeastward along the West Coast throughout the day today and eventually reach Arizona later tonight. This feature will allow 500mb heights to fall leading to much cooler temperatures as well as a chance for valley rain showers and mountain snow across mainly the eastern half of the state. In addition, UA WRF model soundings forecast a relatively shallow layer of instability (CAPE on the order of 100 to 300 J/kg) tomorrow across the region, so an isolated low-topped thunderstorm or two is possible. Rainfall amounts are expected to be light, with between a trace to 0.10 inches in the lower deserts, and between 0.25 and 0.50 inches over the higher terrain with highest amounts possible along the southwestern facing slopes of the Mogollon Rim and White Mountains. Snow levels will remain above 6000 feet with a trace to 6 inches expected with locally higher amounts possible over the tallest peaks. Current Conditions At 3PM
