A quick-moving storm system will bring multiple rounds of rain to the Delmarva region beginning Thursday evening and continuing into Friday morning.
Low pressure tracking into the western Great Lakes will push a surface warm front toward the Mid-Atlantic tonight. As this front approaches, moisture will increase across Delaware and Maryland’s Eastern Shore, leading to widespread precipitation.
Two Rounds of Rain
The first round of rain is expected to develop late Thursday afternoon into the evening, spreading across Delmarva and southern New Jersey. A second round will follow overnight into Friday morning, before gradually tapering off from south to north later in the day.
Rainfall totals across Delmarva are expected to range between 0.30 and 0.50 inches, with some locally higher amounts possible depending on how the heavier bands set up. While flooding is not anticipated, ponding on roadways may occur during periods of steadier rain.
Fog Possible Overnight
As milder, moisture-rich air rides up and over cooler surface air, areas of fog may develop late Thursday night into early Friday morning. Reduced visibility could impact the Friday morning commute, particularly in low-lying and rural areas.
Motorists should be prepared for wet roads and localized visibility reductions overnight and early Friday.
Temperature Gradient Friday
A noticeable temperature difference is expected across Delmarva on Friday due to the position of the warm front. Southern areas may turn milder sooner, while northern portions of the peninsula could remain cooler longer before temperatures gradually moderate.
Milder Conditions for Saturday
Behind the system, winds will shift and temperatures will rebound for Saturday. As cloud cover breaks at times, most of the Delmarva coastal plain should see highs climb into the upper 40s to lower 50s, offering a brief break from the recent chill.
A lingering boundary may remain just north of the region, but only a slight chance of light precipitation is expected near the northern fringe of the area. The majority of Delmarva should stay dry Saturday.
