Some severe potential exists this afternoon for the Sacramento Valley. An upper level low centered just off the northern California coast is forecast to move inland later today. With it will come very cold (-27) 500 temps and steep 1000 to 700 lapse rates (-8). More than adequate CAPE (for California) should be present...the 15Z RUC has 500 + this afternoon over much of the northern Sacramento Valley. This is similar to the setup that spawned several tornadoes last week. The question will be whether or not there's adequate shear. Some surface convergence and good backing flows are currently present in the northern Sac Valley as Chico is reporting SSE at 16 knots. While decent 700 winds (SW at 30 knots) are forecast for late afternoon, the 500 flows look whimpy over the area of greatest instability as the front shifts to the east.
While my buddy Bill and the Tempest folks play with the real severe stuff in the Plains... I'll have to settle for maybe drifting towards the Corning area this afternoon just to see what pops.
