.SYNOPSIS...06/125 PM.
Slightly cooler than normal conditions will continue through midweek due to an upper level low pressure over the West. Night through morning low clouds and fog will continue through the week. There is a slight chance of rain for late in the week for Los Angeles County.
&&
.SHORT TERM (TDY-THU)...06/214 PM.
No major weather issues through mid week as we continue to deal with a weak upper low off the Central Coast. Temperatures will remain slightly below normal and marine layer stratus will push inland each night and clear out most areas by late morning or early afternoon.
Things start to get significantly more complicated Thursday and beyond as what`s left of Hurricane Priscilla advances northwest up the Baja coast. There is a non-zero possibility that the storm`s speed and trajectory will bring some showers to extreme southern LA County as early as Thursday evening, though the vast majority of the latest ensemble runs favor a Friday arrival or not at all. If the leading edge of the outer rain bands are still south of the area then Thursday will look and feel a lot like Wednesday.
.LONG TERM (FRI-MON)...06/214 PM.
There continues to be a lot of uncertainty in the forecast, particularly Friday and Saturday as moisture from Priscilla moves up the Baja Coast while an unseasonably cold upper moves into the coastal waters west of the Bay Area. Chances for rain are still in the forecast across LA County but there is still a considerable range of possible outcomes from heavy rain, lightning, and muggy/warm conditions to no rain, a deep marine layer, and much cooler than normal temperatures. May not get much clarity on this for a few more days. North and west of LA County there is no rain expected from either system and temperatures will be a little below normal.
Sunday and Monday are expected to be dry as both the upper low over northern and central California and the remnants of Priscilla move into the Great Basin and desert southwest respectively. However, a trough will remain along the West coast potentially well into next week, keeping high temperatures below normal. There are also some signals for another potential weak storm system moving into the area early next week but this long range upper pattern has a very low predictability so still many possible outcomes. Though the most likely one (>75%) is dry with near to slightly below normal temperatures.

.MARINE...06/739 AM.
ACross the outer waters and nearshore along the Central Coast conditions are likely to remain below Small Craft Advisory (SCA) criteria through Thursday with increasing winds to near or above SCA levels possible by Friday. SCA winds look likely for the weekend.
For the inner waters south of Point Conception, conditions should generally remain below SCA criteria through mid week. There will then be a 20-40% chance for SCA level winds Thursday and Friday, with the best chances for the Santa Barbara Channel. There is a 60% chance for SCA winds for Saturday evening.
