Discussion

through next Thursday.

A large 564dm low continues to slowly meander across central California this afternoon, with a strong and deep southerly flow out ahead of it. This flow pattern has entrained some deeper surface moisture north into the region over the past couple days, and as the low moves inland today, cooler air aloft is moving in helping to add to the instability present. This is sparking a few corridors of strong thunderstorm activity again this afternoon. Deep layer shear of 40-50 knots or greater is resulting in very fast northward storm motions which is helping to limit the flood threat, but enhancing the risk of small to potentially quarter sized hail. This risk will remain present through the evening hours before instability begins to wane and the corridor of instability and wind shear shifts eastward.

By tomorrow, the low will have moved inland and begun to weaken considerably, but weak troughing will remain over head with lingering terrain driven showers possible. Conditions will continue to dry through the weekend and next week with temperatures returning to near normal.
