A midlevel low will gradually approach the northern CA coast as it loosely phases with a stronger midlevel trough moving eastward across British Columbia on Tuesday. Large-scale ascent preceding the midlevel low will aid in isolated thunderstorm development along the higher terrain of central OR. Around 0.7 inch PW and a deeply mixed boundary layer will favor dry thunderstorms, with an associated risk of lightning-induced ignitions and strong/erratic outflow winds. At the same time, a belt of moderate-strong midlevel winds peripheral to the trough in British Columbia will cross the Cascades. This will promote dry/breezy downslope winds in the Columbia Basin, with the strongest winds expected through the Cascade Gaps. Given dry/receptive fuels, elevated fire-weather conditions are expected. Farther south, moderate deep-layer southwesterly flow ahead of the midlevel low will overspread a well-mixed boundary layer across parts of central/southern NV, where elevated to locally critical fire-weather conditions are expected. ..Weinman.. 07/07/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
