Expect the marine layer to deepen again through Tuesday morning. Onshore flow will continue across the region because of an exiting dip in the jet stream as a low pressure system moves east. We cannot entirely rule out patchy morning drizzle as the clouds get socked in across the coastal basin. By tomorrow afternoon, the marine layer will clear (inland) and we will see afternoon sunshine with some passing clouds. It could be stubborn to clear along the immediate coast. Temperatures will remain near to slightly below seasonal for another day. MORE: https://www.cbs8.com/article/weather/forecast/san-diego-weather-update/509-addbcd08-0811-489a-b511-7cd202ccde99
