DELMARVA -- The weekend across Delmarva will start with low clouds and patchy fog in the morning, but conditions will improve to a pleasant and warm afternoon. Onshore winds will keep humidity in place, with inland highs reaching the mid to upper 80s and coastal areas topping out in the upper 70s to low 80s. Dew points will remain high, in the upper 60s to low 70s, making it feel a bit sticky despite the comfortable temperatures.
Starting the day with some fog/low clouds, mostly sunny afternoon with highs in the mid 80s inland/Eastern Shore, to upper 70s and low 80s at the coast.
High pressure will shift toward the New England coast Saturday night, bringing a cooler and drier night with lows in the 60s to near 70.
Sunday will be the warmest day over the next 5 to 7 days. Cooler air through early next week.
By Sunday, the high will move farther out to sea as a cold front approaches from Canada. Southerly winds will draw warmer, more humid air into the region, pushing highs back into the upper 80s to near 90. Dew points will once again climb into the upper 60s to near 70.
An isolated shower or storm is possible late Sunday afternoon into the evening as the front passes through. However, storm coverage is expected to remain limited, with a low risk for severe weather or flooding. Any lingering showers will move offshore Sunday night as high pressure builds in from the north. Overnight lows will fall into the 60s to near 70.
The cold front will stall over the Mid-Atlantic early in the week as Canadian high pressure builds in from Quebec and New England. Persistent onshore winds Monday and Tuesday will usher in cooler air, keeping highs in the mid-70s to low 80s Monday and dropping temperatures even further on Tuesday.
An upper-level disturbance could bring showers and thunderstorms Tuesday night into Wednesday, followed by drier conditions Thursday and Friday.
Hurricane Erin's center will pass well offshore, but the surf will be dangerous, 6 to 12 ft waves, beach erosion and coastal flooding possible.
WATCHING HURRICANE ERIN — Hurricane Erin, currently several hundred miles east of the Northern Leeward Islands, may bring coastal hazards to Delmarva next week. A high risk for rip currents, rough surf, and possible minor coastal flooding starting Monday and lasting into Thursday. Residents and beachgoers should stay alert to updates.
