We've already been locally warm this week but over the next two days the heat will take a noticeable jump in the coastal and interior valleys. Coastal valley locations will be in the 85-92 degree range with inland valleys 90+ (beaches in the 70s to mid 80s depending on the beach).
There is a heat advisory in place.
There is also a wind advisory in place for the Santa Barbara county mountains, passes and canyons.
The warm weather is driven by a ridge in the upper atmosphere, strong surface high pressure and some night and morning offshore winds.
The ridge stays in place Friday which means inland locations will stay warm but closer to the coast it appears that some onshore flow will pick up and start to slowly bring temperatures back down.
Inland temps will fade a bit into the upcoming weekend.
We'll have to watch the marine layer Sunday/Monday. It is a strong temperature contrast between the interior and higher elevations and the lower elevations could result in a slow to clear marine layer.
And if you are into gambling, there is some model output showing a frontal passage late Monday into Tuesday showing the potential for light showers in SLO county. Looks like next week we'll be in a cooler pattern all week.
