Discussion: Weather warning, watch, and advisories cover the Northeast and East U.S. this morning for the last blast of arctic air of the winter season (Fig. 1). Added are High Wind Warnings for the Mid-Atlantic region which drive wind chill to -10F to -20F shortly after dawn tomorrow once the arctic air arrives. Fresh snow helps to enhance the incoming cold (Fig. 2). The cold burst marks the coldest air mass of the season for NEPOOL (Fig. 3) with the second coldest for PJM-East. The U.S. gas population weight HDD forecast indicates a sharp decrease in heating demand for mid-to-late February (Fig. 4).
