Severe weather potential ramps up Sunday afternoon into the evening as showers and thunderstorms develop from northwest to southeast, with the greatest risk roughly between 4:00 p.m. and 10:00 p.m.
The main threats look to be damaging wind gusts and some large hail, especially from about the I-95 corridor north and west, though a brief isolated severe storm cannot be ruled out elsewhere.

Heavy downpours may also lead to localized flooding in urban areas. By late Sunday night into Monday midday, a strong cold front clears the region, ending the storms and bringing gusty winds with falling temperatures through the day.
