USED AN EVEN BLEND OF THE MOST RECENT ECENS AND NAEFS MEANS AS A
SYNOPTIC BASE FOR THIS FORECAST PERIOD. THE TWO MEANS ARE WELL
CORRELATED EARLY ON, BUT BY DAYS 6 AND 7, A SMALL WAVELENGTH
DIFFERENCE EMERGES THAT IS AMENABLE THROUGH ARITHMETIC BLENDING.
THE EAST CONTINUES COLD, WHILE THE WEST COAST GETS SIGNIFICANTLY
WETTER WITH THE GRADUAL PROGRESSION OF THE LONGWAVE TROUGH
HERETOFORE ANCHORED OFFSHORE. THE CHANCES OF ANOTHER EAST COAST
WINTER STORM HAVE DIMINISHED SOMEWHAT THIS MODEL CYCLE, THOUGH A
LAGGED OR MULTI-DAY PERSPECTIVE NECESSITATES KEEPING THE
POSSIBILITY IN PLAY.
