Maryland Weather: More rain likely overnight into Sunday

BALTIMORE-- More periods of rain are likely overnight through the day on Sunday. Steady rain tapers off before Sunday evening.

A Coastal Flood Warning begins at 11 PM tonight and continues through 8 AM Sunday. Moderate coastal flooding is expected in parts of Anne Arundel county at the time of high tide Sunday. More moderate flooding is likely during Monday morning's high tide cycle. 

On and off rain will continue through the overnight hours. Rain will be light to moderate in intensity. There will also be patchy areas of fog developing. While flooding is not expected, roads will be wet and slick, so please drive with extra caution. 

Steadier rain appears likely throughout the daytime hours on Sunday. Along with the rainy weather, temperatures will be a bit warmer with highs near 70 degrees. 

Monday will be warm and muggy with scattered showers and thunderstorms developing, especially during the afternoon and evening hours. These storms will be hit or miss, but any of the storms will have the capability to bring and deliver heavier downpours, lightning, thunder, and gusty winds. 

From Tuesday, attention turns to a low-pressure system moving north through the Great Lakes, which will shift the cold front northward as a warm front, with another cold front approaching from the west. This setup increases the likelihood of strong to severe thunderstorms through the end of the week especially since temperatures will return to the 80s for highs providing the heat needed for storms. There may also be a potential for flooding by mid-week, given the already wet conditions from the weekend.

High temperatures this upcoming week will be warm, but it will also be quite humid. Look for highs in the lower 80s Monday and Tuesday. Mid to upper 80s Wednesday. Cooling off by Friday and Saturday back into the 70s.
