As a deep cut off low establishes itself over Northern California later this week, a large warm sector develops over the Great Basin… with dry SW flow off of the ocean but mid level instability aloft. My concern for the Great Basin region is the potential for a large lightning bust over a couple day period. The sounding shows a large inverted V profile especially initially, and cloud cover could inhibit surface based day time convection that would bring wetting rains… favoring an elevated based thunderstorm regime during the overnight hours.
