A low pressure system racing northward through the Carolinas will send alternating rounds of rain and snow into the D.C. region from late Sunday morning into the overnight hours on Monday.
Wintry weather will make an impact in the D.C. area starting Sunday afternoon and evening with a mix of snow, sleet and rain, the National Weather Service said.
Affected areas include, Annapolis, D.C., Upper Marlboro in Maryland, and Fairfax, Fredericksburg, and Charlottesville in Virginia.

Storm Team 4 Somara Theodore says the system is expected to come into the region around brunch time.
“The D.C. metro area will teeter along that rain snow line. Therefore, what may start off as some snow fall will quickly change to a mix including sleet and rain then as the (temperatures) drop Sunday night, that could change back to snow before it heads out early Monday morning,” Theodore said.
What NBC Washington’s Lauryn Ricketts called a “tug of war” between a colder air mass over the Great Lakes and a warmer current from the Gulf of Mexico will lead to precipitation bouncing back and forth from rain to snow somewhat unpredictably starting late Sunday morning.
“D.C. will be playing tug of war between cold and warm air, therefore the Washington area will likely be changing back and forth from snow to rain through the duration of this evening,” NBC meteorologist Lauryn Ricketts said. “Areas north and west will be all snow, and locations south and east will stay all rain.”

Areas under the winter weather advisory are likely to see snow covered roads and issues with the Monday morning commute.
The system will then depart quickly and bring about plenty of sunshine and breezy conditions for the next following days.
The next week should be dry, though another disturbance will bring rain next weekend, said Theodore.
