DELMARVA - Residents and visitors in coastal Sussex County can expect a tranquil start to the week with sunshine and pleasant weather through late Tuesday, before conditions shift significantly with the arrival of a slow-moving storm system.
A strong high-pressure system over eastern Canada is currently pushing cool, dry air into the region. Monday will see abundant sunshine with just a few afternoon clouds and high temperatures reaching the upper 60s to low 70s along the coast. Winds will be breezy, gusting up to 30 mph at times, but less intense than recent days.
Clear skies and calming winds will persist into Monday night, with temperatures dipping into the low 50s near the beaches. Despite the chilly air, no frost is expected due to low humidity levels.
By Tuesday, the high pressure continues to hold influence, providing another mostly sunny day with increasing high clouds during the afternoon. Highs are forecast to remain in the upper 60s to low 70s, and winds will ease further compared to Monday.
However, conditions begin to deteriorate late Tuesday as a storm system approaches from the Great Lakes. Rain is expected to spread from west to east overnight into Wednesday, ushering in a period of steady, and at times heavy, rainfall across the Delaware coast.
The Weather Prediction Center has placed the region under a Marginal Risk for excessive rainfall, with expected totals ranging from 1 to 1.5 inches through Wednesday night. Poor drainage and nuisance flooding are possible. Winds will also increase, particularly along the coast, where sustained speeds of 15 to 25 mph with gusts up to 35 mph are likely by late Wednesday.
Temperatures on Wednesday will be notably cooler, with highs struggling to reach the low 60s. Rain and cloudy skies persist into Thursday, though rainfall is expected to become lighter as the system slowly exits the region.
Looking ahead to the weekend, the unsettled pattern continues, with daily chances for scattered showers under cloudy skies through Saturday. While it won't be a complete washout, outdoor plans may require flexibility. By Sunday, conditions look to improve, with a shift toward drier and sunnier weather and gradually warming temperatures.
