NOAA/NWS Forecast Discussion:
Aside from an initial band and latter pulses of moderate rainfall throughout the event, upslope moisture transport remains elevated through late Thursday. This will allow for substantial orographic enhancement along favored coastal ranges such as the Santa Lucia and Santa Cruz Mtns.
Touching on previous discussions and details regarding model uncertainty; really not much change in the forecast today. Ensemble guidance still on the order of 1″ across most lower elevation locations, 2-3″ for coastal areas, locally up to 3-4″ for coastal ranges across the period from Tuesday to Thursday.
