DELMARVA - A changing weather pattern is in store for Delaware’s beach towns and inland cities from early Friday through early Sunday morning, as a series of frontal systems push through the area bringing periods of rain, fluctuating temperatures, and elevated allergy concerns.
Friday Morning Through Friday Evening:
Conditions will start out dry and unseasonably warm across the region Friday morning, thanks to high pressure situated offshore. This setup brings in southerly winds and a noticeable increase in humidity. Temperatures are expected to rise into the mid-70s along the coast, and near 80 degrees in inland cities like Georgetown and Seaford. Skies will remain partly sunny throughout the day, but cloud cover will gradually increase as a warm front approaches from the southwest.
Friday Night Through Saturday Evening:
Rain begins to move into the region Friday night as the warm front lifts through the area, linked to a developing low-pressure system over the Great Lakes. Widespread showers are likely overnight, with rain continuing into Saturday as a cold front sweeps through during the day. While rainfall totals will remain modest—generally around a quarter inch in Sussex County—localized heavier downpours are possible farther north. A few rumbles of thunder may occur, but severe storms are not expected.
Daytime highs Saturday will be cooler than Friday, with temperatures topping out in the upper 60s to near 70 degrees. Showers will taper off by Saturday evening as the cold front moves offshore.
Saturday Night Into Early Sunday Morning:
Skies will begin to clear Saturday night as high pressure builds in from the Great Lakes. By early Sunday morning, the region will see a return to dry conditions, cooler temperatures, and a light northwest breeze. Morning lows could dip into the upper 40s inland, with coastal towns seeing lows in the low 50s.
Air Quality and Allergy Outlook:
Despite the rainfall, air quality will remain in the "moderate" range, particularly on Friday and early Saturday, due to lingering pollutants and pollen. Allergy sufferers should remain cautious, as tree pollen levels are still elevated across Sussex County. The incoming rain may briefly dampen pollen levels, but a return to sunshine Sunday may cause them to rebound quickly.
Outlook:
Sunday promises bright skies and seasonable temperatures as high pressure settles into the Mid-Atlantic, offering a quiet and refreshing end to the weekend before the next weather system approaches later next week.
