<div> </div>
<div style="padding-left: 36pt; ">Upper level trough will approach tonight and stretch to the south keeping the air mass cool and unstable. Expect a few lingering showers but mainly over the mountains. Otherwise look for partly to mostly cloudy skies. Wind
flow will be light onshore but with good mixing, smoke dispersion should be mostly good.</div>

<div> OUTLOOK (SATURDAY - MONDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough weakens and moves to the east Saturday allowing for a minor upper level ridge to build in. Air mass will warm and dry some. Next front and trough move in on Easter and promise to bring plenty of moisture
to most locations. Expect fairly breezy conditions as well with this rather strong late season front. Front moves by to the east later Sunday with the upper trough following on Monday. Snow level will lower from 6000 – 7000 ft Sunday to the valley floors
Monday morning. Air mass will remain mostly unstable through the period and smoke dispersion good to excellent.</div>
