..DISCUSSION
A BROAD/EXPANSIVE UPPER-LEVEL TROUGH WILL PERSIST OVER MUCH OF THE
EASTERN U.S. DURING THE UPCOMING WEEK, WHILE A RIDGE OF HIGH
PRESSURE WILL EXTEND OVER THE WESTERN PORTION OF THE CONUS. A SERIES
OF SURFACE HIGH-PRESSURE SYSTEMS WILL RESULT IN GENERALLY DRY/STABLE
CONDITIONS AND MINIMAL TO NO CHANCE FOR THUNDERSTORMS THROUGH
FRIDAY/DAY 6. TOWARDS SATURDAY/SUNDAY (DAYS 7 AND 8), GUIDANCE IS
VARIED BUT DOES SUGGEST SOME INCREASE IN THUNDERSTORM POTENTIAL OVER
THE SOUTH-CENTRAL U.S. AS AN IMPULSE OVER THE WESTERN U.S. MOVES
EAST OF THE ROCKIES. UNCERTAINTY IS HIGH AT THIS RELATIVELY EXTENDED
RANGE ON THE TIMING AND DEGREE OF AMPLIFICATION OF THIS FEATURE, AND
THEREFORE THE OVERALL POTENTIAL FOR THUNDERSTORMS REMAINS LOW WITH
THIS OUTLOOK.
