.DISCUSSION...
An eastward moving system will continue to bring rain showers
near the fire through early this evening. Total rainfall
accumulation is forecast to be between 0.02 to 0.12 inches. This
afternoon mild instability will support a 10% chance of thunder.
Colder temps and recent rains behind the system will support
higher RHs through Monday morning, and on Sunday morning RHs near
saturation could allow patchy fog development in valleys. Warming
and drying continues through this week, with a slight chance for
showers Tuesday evening.
