Today will mainly be a transitional day where the surface winds will shift from northerly to southerly. Some moisture will be reintroduced to the environment and instability will be decent. Wednesday, surface winds will be primarily southerly, which will enhance warm air advection and moisture in the area. As a result, highs this week are forecast to be in the low 90s with apparent temperatures in the mid-high 90s.
Thursday and Friday, conditions will be dry based on the model consensus. Upper level high-pressure will be the main pattern over the area.

Looking at the models, an isolated shower could be possible in the coastal marine areas Friday night due to an influx of tropical moisture. But overall, a hot and dry couple of days at the end of the workweek with highs forecast in the low 90s.
