Drier air courtesy of high pressure wedging southwestward across the area will characterize the rest of the work week, bringing slightly more comfortable dewpoints to the area and seasonable temperatures for mid-September.
A front coming through on Tuesday will knock temperatures back from the record levels of the past two days, bringing some breezy conditions and maybe some coastal flooding in the process. We start the day in similar fashion to the past couple days, with lows in the mid-70s expected. High pressure building south will swing winds around to the east and northeast in the morning, turning things gusty in the process (especially at the coast). This wind may also help drive tidal departures higher, perhaps causing some minor coastal flooding with the midday high tide. Widespread flooding issues are not expected, though. We will see dewpoints begin to drop during the afternoon with highs peaking just in the upper 80s, right around mid-September normals.
We tied a record high Sunday, and should at least threaten if not break the daily record again on Monday. From there, slightly cooler high pressure builds in from the northeast, bringing a little whiff of more seasonable air for mid-September.
