VALID 201200Z - 251200Z

...DISCUSSION...

MODEL CONSENSUS IS THAT LONGWAVE PATTERN WILL REMAIN DOMINATED BY A
TROUGH OVER THE ERN HALF OF THE COUNTRY THROUGH ABOUT DAY 6...WHICH
WILL PROMOTE OFFSHORE FLOW AND STABLE CONDITIONS INLAND. BEYOND THIS
TIME THERE IS SOME INDICATION THAT THIS PATTERN WILL BEGIN TO BREAK
DOWN INTO A MORE PROGRESSIVE REGIME...BUT SOLUTIONS BECOME
INCREASINGLY DISPERSIVE WITH LOW PREDICTABILITY.
