A weak weather system is expected to move in from the northwest and then form a cutoff low across central/southern CA from later today through Thursday with light showers and possible thunderstorms mainly across the Sierra and points east over NV.
Models continue to show another elongated polar system traversing the region Friday through the weekend bringing widespread below normal temperatures and scattered precip over much of the area. Best amounts over the Sierra and eastward into NV.
Runoff in basins with suffecient snow will gradually rise the next couple of days. Rain and cloud cover will lead to increased uncertainity in river levels later in the week.
