RELIED ON THE 00Z/27 EUROPEAN CENTRE ENSEMBLE MEAN FOR THE FRONTS
AND PRESSURES THIS FORECAST CYCLE. THERE HAS BEEN POOR RUN-TO-RUN
CONTINUITY AMONG ALL THE GLOBAL NUMERICAL MODELS WITH REGARD TO
THE FLOW OVER CANADA AT THE MEDIUM RANGE, SO TOOK ADVANTAGE OF THE
RELATIVELY ROBUST CORRELATION AMONG THE ENSEMBLE MEANS--REASONABLY
REPRESENTED BY THE LATEST ECENS MEAN. THE PATTERN FEATURES A
PROLONGED STRETCH OF RELATIVELY HIGH HEIGHTS OVER THE EASTERN
UNITED STATES, WHICH WILL AFFORD THAT REGION SOME OF THE SUMMERY
CONDITIONS THAT HAVE BEEN LACKING THIS YEAR. FOR THE REMAINDER OF
THE NATION, THE POLAR JET SHOULD KEEP THE NORTHWEST ON THE COOL
SIDE, THE SOUTHWEST MONSOON SUPPRESSED, AND THE REGION FROM THE
ROCKIES TO THE APPALACHIANS QUITE SHOWERY.
