A very broad, upper level low remains stalled out over the region, drawing in subtropical moisture from the east for a chance of showers and thunderstorms at times through Thursday; cooler for the weekend as a trough deepens across the west. Wednesday we'll peak in available moisture and instability to trigger scattered showers and thunderstorms, one factor that could limit convection will be the lack of surface heating if we remain overcast, but could counter that as low pressure moves overhead; highs in the mid to upper 60's. Moisture decreases Thursday along with the potential for showers & storms as temperatures warm back up around 70 by Friday. Over the weekend we'll experience another nice cool down as a trough pushes through the west coast, knocking our daytime temps back in the lower to mid-60's, while overnight lows also dip into the 20's with fairly seasonal, dry fall weather expected next week.
