EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1258 AM EDT WED JUL 29 2015

VALID 12Z SAT AUG 01 2015 - 12Z WED AUG 05 2015


USED THE 12Z/28 ECENS AND NAEFS MEANS AS SYNOPTIC GUIDES THIS
FORECAST PACKAGE. THE OPERATIONAL MODELS FROM THE 12Z/28 AND
18Z/28 CYCLES WERE DIFFERENT ENOUGH IN SYNOPTIC DETAIL TO PRECLUDE
THE INCORPORATION OF ANY OF THEIR SOLUTIONS INTO THE MANUAL BLEND.
LITTLE CHANGE IS ANTICIPATED IN THE LARGE-SCALE FLOW PATTERN
ACROSS THE NATION, WITH A MEAN RIDGE IN THE WEST AND A BROAD
TROUGH EAST OF THE ROCKIES TO THE APPALACHIANS. MOST OF THE
RAINFALL THIS PERIOD SHOULD FOCUS ALONG AND SOUTH OF THE
DISSIPATING POLAR FRONT IN THE SOUTHEAST, WITH SCATTERED
CONVECTION IN THE MONSOONAL REGIONS OF THE SOUTHWEST AND ASTRIDE
THE POLAR FRONT IN THE NORTH CENTRAL STATES.
