Wider weather episode

This storm ushered in cooler temperatures, as well as our initial round of showers, including snow showers across the highest terrain. A cold front that pushed across northern CA, and southern OR, early morning on the 15th spread the shower potential southward along the front with precipitation starting in western Nevada by mid-morning, and the eastern Sierra by the early afternoon. Showers persisted into the rest of central/eastern Nevada through the early evening. Blended guidance shows fairly high thunderstorm probabilities with 15-20% across the Basin and Range into western Nevada, and the highest chances (20-30%) across the Tahoe Basin and northeastern CA. Storm totals remained around 0.05-0.25 for much of the area, especially for northern Washoe and Lassen counties. Lower precipitation amounts (around 0.10 or less) were forecasted for areas south of I-80 in Mono and Mineral counties.
