..DISCUSSION
THE SEVERE POTENTIAL REMAINS LIMITED THROUGH THE DAY 4-8 PERIOD. ON
D4/FRIDAY, AN UPPER LEVEL TROUGH WILL BE LOCATED ACROSS THE EASTERN
US WITH STRENGTHENING UPPER LEVEL RIDGING ACROSS THE WESTERN US INTO
THE ROCKIES. ALONG THE DRYLINE IN FAR WESTERN TEXAS, A FEW
THUNDERSTORMS CAPABLE OF LARGE HAIL WILL BE POSSIBLE. THIS THREAT
MAY BE LIMITED IN DURATION AND COVERAGE BY THE SOUTHWARD MOVING COLD
FRONT EXPECTED TO EXTEND FROM THE SOUTHERN PLAINS INTO THE
NORTHEASTERN US. AS THIS FRONT SHIFTS SOUTHWARD AND A SURFACE HIGH
BUILDS IN ACROSS THE CENTRAL US D5/SATURDAY INTO D6/SUNDAY, MOISTURE
WILL BE SCOURED OUT OF MUCH OF THE CONUS LIMITING THE SEVERE THREAT.
AS THE SURFACE HIGH SHIFTS EASTWARD ACROSS THE MIDWEST, SLOW
MOISTURE RETURN WILL BEGIN ACROSS THE SOUTHERN PLAINS LATE D6/SUNDAY
INTO D7/MONDAY. DURING THIS PERIOD, THE NEXT UPPER-LEVEL WAVE WILL
BE DEEPENING ACROSS THE WESTERN US. AS THIS SYSTEM EVOLVES, SEVERE
POTENTIAL MAY RETURN LATE IN THE PERIOD ACROSS PORTIONS OF THE
SOUTHERN AND CENTRAL PLAINS.
