STATUS QUO AT THE MEDIUM RANGE. THE WESTERN RIDGE/EASTERN TROUGH
PATTERN FILLS WITH TIME, BUT STAYS PUT. THE ENSEMBLE MEANS FROM
THE VARIOUS MODELING CENTERS ARE DUPLICATES OF ONE ANOTHER, WITH
ONLY THE OPERATIONAL/DETERMINISTIC SOLUTIONS MARKED BY ANY
VARIANCE. THE SPREAD IN THE OPERATIONAL MODELS IS CONFINED TO
CANADA, WHERE THE ECMWF IS MORE AMPLIFIED WITH THE NEXT NORTHERN
NORTHERN STREAM AMPLIFICATION THAN THE GFS. WENT WITH THE MEANS
SINCE THE AREA OF SENSITIVITY IN THE GUIDANCE WITH RESPECT TO THE
CANADIAN FLOW IS WITHIN THE ARCTIC CIRCLE--NEVER AN EASY REGION TO
DIAGNOSE.

THE SENSIBLE WEATHER HIGHLIGHTS CONTINUE TO BE THE SUPPRESSED
AFTERNOON TEMPERATURES WHERE IT REMAINS SHOWERY EAST OF THE
ROCKIES, THE MULTI-DAY RAINFALL POTENTIAL FOR AREAS ALONG AND ON
THE COLD SIDE OF THE POLAR FRONT FROM THE CENTRAL HIGH PLAINS TO
THE SOUTHEAST, THE FOCUSED MONSOON INTO THE SOUTHWEST, AND THE
ONGOING ANOMALOUSLY HOT WEATHER IN EASTERN WASHINGTON STATE.
