Temperatures vary widely this Sunday from 23 in Frederick - where light snow has fallen - to a milder 35 at Reagan National. Rain is falling across much of the metro area with some of it, mostly to the north and west of the city, freezing on contact with the ground. A Freezing Rain Advisory, in fact, is in effect through midday for most of the DC metro area; the Advisory has been dropped for DC itself, Prince George's and Anne Arundel counties. A light glaze of 01. to 0.2 inches is possible on untreated road surfaces in the Advisory areas. With temperatures projected to rise near 40, any frozen precipitation will likely become all rain by afternoon.
Temperatures will likely stay steady or rise a bit overnight as the rain continues. Monday however will feature a dramatic shift as a cold front front approaches. Rain could mix with or change to snow in the morning before the day turns mostly sunny, very windy, and much colder. The mercury will continue to fall through the afternoon as arctic air moves rapidly toward the Mid-Atlantic. Low temperatures on Monday night will likely drop into the single digits with wind chill values below zero. Tuesday could b the coldest day in almost 20 years with a daytime high in the teens and wind chill values as low as 15 below zero. Thereafter, temperatures will slowly moderate with highs reaching the mid 40s by Friday and Saturday. So while the bitterly cold air's visit will be brief, it will be dangerous. Avoiding the outdoors for extended periods is well advised. Have a good Sunday.
