Areas affected...Parts of northern CA

Concerning...Severe potential...Watch unlikely=20

Valid 052026Z - 052230Z

Probability of Watch Issuance...5 percent

SUMMARY...Storms capable of localized strong/severe gusts and
perhaps some hail may increase through the afternoon.

DISCUSSION...Despite generally limited low-level moisture, strong
diurnal heating has resulted in modest destabilization across parts
of northern CA, with MLCAPE increasing to near or above 500 J/kg.
Widely scattered thunderstorms have already initiated, and
additional development is expected through the remainder of the
afternoon, especially across terrain-favored areas. Deep-layer shear
will remain relatively weak, but midlevel easterly flow to the north
of a mid/upper-level low near the coast of southern CA will support westward-moving cells/clusters through the afternoon.=20

Steep midlevel lapse rates will support isolated hail potential with
initial storm development across relatively higher elevation areas.
With very steep low-level lapse rates, some threat for localized
strong/severe gusts will accompany any stronger outflow-driven
clusters that spread into the lower elevations. The severe threat is
expected to remain too marginal and isolated for watch issuance.
