The Climate Impact Company Winter 2017-18 Outlook is issued. The forecast indicates another warmer than normal winter season as observed the 2 previous cold seasons. The warmest anomalies are in the Northeast U.S. where winter heating demand is largest. The month-to-month variability indicates the only anomalous cold weather of winter ahead is in the Northwest to Central U.S. in December. Northern U.S. snow cover to help drive cold weather does not develop and the lack of snow is a primary drive of the winter chill in the Midwest to Northeast Corridor. The forecast indicates needed rainfall and mountain snow eases new drought concerns from northern California to Washington. The outlook is based on a SSTA-based constructed analog favoring near neutral ENSO and Pacific decadal oscillation (with weak cool phase tendencies) and a warm Atlantic multi-decadal oscillation. A strong positive phase North Atlantic oscillation is expected in January causing a warm mid-winter.
