EXTENDED FORECAST DISCUSSION

VALID 12Z MON APR 28 2014 - 12Z FRI MAY 02 2014


RELIED ON THE 12Z/24 ECENS MEAN FOR THE FRONTS AND PRESSURES FOR
DAYS 3 THROUGH 7, BLENDING IN A SLIGHT AMOUNT OF THE 18Z/24 GEFS
MEAN FOR THE TEMPERATURES AND POPS TO MITIGATE SOME OF THE BIASES
OF THE EUROPEAN CENTRE GUIDANCE FOR THOSE FIELDS. THESE MEANS
SIDESTEPPED SOME OF THE EXTREMES THAT THE OTHER MODELS AND MEANS
DEPICTED. THE PATTERN IS A BLOCKY ONE, WITH VERY LITTLE
WEST-T0-EAST MOVEMENT OF FEATURES ACROSS THE NATION. THE WEST
LOOKS MOSTLY DRY, WITH THE EAST--PARTICULARLY EAST OF THE
MISSISSIPPI--QUITE WET. SEVERAL INCHES OF RAINFALL ARE LIKELY IN
PARTS OF THE EAST WITH THE SLOW-MOVING FRONTAL SYSTEM THROUGHOUT
THE PERIOD. SOME ENERGY BLEEDING INTO THE WEST SHOULD ALLOW FOR
SOME LATE-SEASON SNOWS IN THE CENTRAL HIGH PLAINS. THE SUPPRESSED
POLAR JET WILL PRECLUDE ANY WIDESPREAD HEAT.
