Very little precipitation and becoming summerlike as strong ridging builds in midweek and beyond…
Mostly sunny skies are expected on Tuesday with temperatures nudging north of average and very close to the 80° mark. It remains mostly clear overnight, but temperatures remain relatively mild during the nighttime hours.
Continuing to moderate well into the 80s on Wednesday with an upper level ridge moving into the region. This ridge will become well established in the late week period, with temperatures well into the 80s Thursday and Friday. As the ridge shifts to our SW on Friday, it creates a northwesterly wind flow over the weekend which keeps humidity in check, but does nothing to abate surface temperatures. In fact, a run at 90° is possible or very close to it. A shortwave rounding the outer periphery of the retrograding ridge could bring showers finally by Monday.
