VALID 12Z TUE MAR 31 2015 - 12Z SAT APR 04 2015


FELT IT WAS TIME TO MAKE SOME BIG CHANGES ACROSS THE CONTIGUOUS
UNITED STATES AT THE MEDIUM RANGE THIS FORECAST CYCLE. THE MORE
AMPLIFIED EUROPEAN CENTRE SOLUTIONS OF THE PAST COUPLE DAYS ARE
BEING MET AT LEAST HALFWAY BY THE 00Z/28 CANADIAN MODELS AND--TO A
LESSER EXTENT--THE 06Z/28 GFS/GEFS. BLENDED THE 00Z/28 GDPS WITH
THE 06Z/28 GEFS MEAN AS A SYNOPTIC GUIDE FOR FRONTS AND
PRESSURES--A NOD TOWARD MORE AMPLITUDE WITHOUT COMMITTING TO THE
FULLY-PHASED EUROPEAN CENTRE GUIDANCE. EVEN THE "BLENDED CYCLONE"
DAYS 6 AND 7 IN THIS NEW WPC PACKAGE HAS A SIGNIFICANT ATTENDANT
UPTICK IN RAINFALL, SNOWFALL, AND SEVERE-WEATHER POTENTIAL FROM
THE CENTRAL STATES TO THE EAST. THE WEST COAST IS ALSO STORMIER
THIS PACKAGE LATE DAY 6 INTO DAY 7, WHEN A COLD LOW IS EXPECTED TO
TUCK INTO THE REGION FROM THE NORTHWEST.
