..DISCUSSION
MEDIUM-RANGE MODEL GUIDANCE IS IN GOOD AGREEMENT IN SHOWING THE
DEVELOPMENT OF A LARGE-SCALE MID-LEVEL TROUGH OVER THE EASTERN U.S.
ON SUNDAY (DAY 4) BEFORE EXITING THE EAST COAST INTO THE WESTERN
ATLANTIC ON MONDAY (DAY 5). A LOW-AMPLITUDE/ZONAL-FLOW PATTERN WILL
SUBSEQUENTLY OVERSPREAD AND INFLUENCE CONDITIONS ACROSS MUCH OF THE
LOWER 48 ON TUESDAY (DAY 6). MODELS VARY CONSIDERABLY BY LATE IN
THE EXTENDED PERIOD REGARDING THE UPPER-LEVEL PATTERN. IN SUMMARY,
A LOW-POTENTIAL SEVERE HIGHLIGHT WILL CHARACTERIZE THE EXTENDED
PERIOD.
