<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge will build into the state tonight and Friday bringing sunshine and warmer temperatures. Air mass will stabilize some during the night and morning hours but daytime heating should provide good mixing. Wind
flow will be light, favoring offshore to northerly flow as surface high pressure builds to the north. Smoke dispersion will be mostly fair.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge continues to build over the state on Saturday and Sunday, further stabilizing the air mass. Ridge will then drift eastward later Sunday, opening the door for the next frontal system on Monday. Expect mostly
sunny skies and warm temperatures through Sunday. The approaching trough will likely set off an evening marine push on Sunday. Clouds increase Monday with moisture possibly moving in during the late afternoon to early evening. Air mass destabilizes and smoke
dispersion improves Monday as the front and trough move in.</div>
