<div style="padding-left: 36pt; ">Upper level low will essentially remain in place along the central California coast, rotating clouds and moisture over the region from the east to southeast. Expect an increased threat of showers and thundershowers over much
of the state, especially south. Air mass will be stable during the night and early morning hours, gradually destabilizing during the afternoon. Wind flow will be light and erratic, mainly favoring a south to northwest flow. Smoke dispersion should be mostly
poor to fair.</div>

<div> OUTLOOK (FRIDAY - SUNDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level low starts weakening on Friday and shifts inland over the weekend, becoming a trough over the intermountain region. Air mass will gradually dry out and showers decrease. Expect mostly fair skies with temperatures
near normal. Air mass will be mostly stable during the morning hours becoming somewhat unstable during the afternoon. Smoke dispersion will be mostly fair.</div>
