VALID 12Z SUN OCT 26 2014 - 12Z THU OCT 30 2014


WITH THE OPENING OF THE FLOW INTO A ZONAL REGIME ACROSS CENTRAL
NORTH AMERICA AT THE MEDIUM RANGE, THE ENSEMBLE MEANS CONTINUE TO
OFFER LESS NOISE AND A SMOOTHER TRANSITION THAN ANY GIVEN
OPERATIONAL SOLUTION. ZONAL ALWAYS MEANS MILDER FROM NOW THROUGH
THE SPRING, AND INDEED, NO ARCTIC INTRUSIONS SEEM LIKELY FOR SOME
TIME TO COME. ZONAL ALSO MEANS WETTER FOR THE WEST, AND IN THIS
CASE, WETTER FOR THE MIDWEST SINCE THAT REGION BEGINS THE PERIOD
WITH NORTHERLY FLOW. SNOW LEVELS IN THE WEST SHOULD DROP ON
AVERAGE THIS PERIOD, WITH MANY OF THE RANGES ON THE POLEWARD SIDE
OF 40N SEEING SOME ACCUMULATION. THE NORTHERN WASHINGTON CASCADES
LOOKS TO RECEIVE THE MOST SNOW DURING THE NEXT WEEK, WITH TOTALS
IN THE FEET IN FAVORED LOCATIONS.
