<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge is building over the region today as a warm front moves in from the coast. Very little, if any, moisture is expected from the front. Cold front will follow Friday morning. Again, moisture amounts will be
minimal as the front dissipates as it moves in. Front will do little damage to the upper ridge which will quickly pop up again Friday evening. Air mass will remain mostly stable with fair smoke dispersion.</div>

<div> OUTLOOK (SATURDAY - MONDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Next warm front will move into the ridge Saturday afternoon and evening bringing some light moisture by nightfall. Cold front and trough will approach on Sunday increasing the chance of moisture and increasing the wind. The
first cold front should move through overnight Sunday/Monday with a second one moving in late Monday. Air mass will be quite stable Saturday with poor smoke dispersion. Mixing and dispersion improve Sunday and Monday.</div>
