EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1117 AM EDT SAT APR 12 2014

VALID 12Z TUE APR 15 2014 - 12Z SAT APR 19 2014


IN THE WAKE OF THE STRONG, ENERGETIC FRONTAL SYSTEM PROGGED BY ALL
THE GUIDANCE TO PUSH OFF THE EAST COAST LATE DAY 3, A SLOWING OF
THE WEST-TO-EAST PROGRESSION OF SYSTEMS ACROSS THE UNITED STATES
IS MAKING FOR HIGH SPREAD AND LOW CONFIDENCE IN THE BEHAVIOR OF
INDIVIDUAL SYNOPTIC SYSTEMS AFTER DAY 5. WITH NO CLUSTERING AMONG
THE OPERATIONAL RUNS FROM THE VARIOUS MODELING CENTERS, RELIED ON
THE HOPEFUL POSITIVE CORRELATION BETWEEN THE 00Z/12 ECENS AND
NAEFS MEANS. THE WEAKER SYSTEMS AND HIGH SPREAD ARE TAKING THEIR
TOLL ON MANUAL PRESSURE, WIND, TEMPERATURE, AND POP FORECASTS,
WITH FAIRLY DILUTE, UNIFORM MASS FIELDS DAYS 6 AND 7. THE SAFEST
THING TO SAY ABOUT THE SECOND HALF OF THE CURRENT FORECAST IS THAT
CLOUDS AND PRECIPITATION SHOULD KEEP DAYTIME TEMPERATURES ON THE
COOLER SIDE FOR MUCH OF THE NATION. THE SOUTHWEST STILL LOOKS
SHELTERED FROM DEEP-LAYER MOISTURE AND THE PASSAGE OF STRONGER
SHORTWAVES.
