Washington D.C. is currently grappling with frigid temperatures, as the mercury plunges to the low teens. According to the Capital Weather Gang, while the immediate forecast indicates clear and calm conditions, residents should brace for a potential significant winter storm this weekend. The storm is anticipated to arrive late Saturday or early Sunday and could extend into Monday morning. The exact trajectory of the storm remains uncertain, leading to potential variations in snowfall accumulations, and the possibility of mixed precipitation, including sleet or freezing rain. Current weather model simulations suggest a wide range of possible snowfall, from no accumulation to over 15 inches, highlighting the unpredictability of the impending weather event.
