delmarva – Showers will continue into the night as a cold front approaches from the northwest. The presence of a weak surface low may promote ascent, leading to more widespread rainfall. Although limited, the forecast remains unstable, which may continue to limit significant lightning activity. However, there is less risk of stronger storms triggering local downbursts due to deep shear and warm, moist conditions. Flash flooding remains a concern due to high levels of moisture in the atmosphere.
Thursday morning and afternoon:
Showers are expected to continue Thursday morning with a few thunderstorms possible as a short wave moves through Delmarva. Cloud cover will remain widespread, limiting daytime warming and thus reducing overall storm intensity. Still, conditions will be favorable for heavy rainfall. The development of any stronger convective core could produce very heavy downpours, leading to localized flash flooding. By Thursday afternoon, the shortwave will begin to move out of the area, gradually reducing the intensity and coverage of the showers.
Appearance:
By Friday, high pressure will develop over the area, bringing drier and stable weather that will continue into the weekend and early next week. The next significant weather system isn't expected until Tuesday.
