..DISCUSSION
SEVERE THUNDERSTORM POTENTIAL WILL REMAIN LOW ON DAYS 4-5/FRI-SAT AS
A COLD FRONTAL PASSAGE AND SURFACE HIGH PRESSURE OVER THE CENTRAL
U.S. LEAVE A DRY/STABLE AIRMASS ACROSS MUCH OF THE CONUS EAST OF THE
ROCKIES.
ON SATURDAY, LOWER-AMPLITUDE, QUASI-ZONAL FLOW OVER MUCH OF THE U.S.
WILL AMPLIFY AS A SHORTWAVE UPPER TROUGH DEEPENS OVER THE ROCKIES
AND EMERGES OVER THE HIGH PLAINS BY DAY 6/SUNDAY MORNING. AS THIS
OCCURS, MODEST GULF MOISTURE WILL RETURN NORTHWARD ACROSS EAST TX
INTO THE MID-SOUTH. A STRONG SURFACE LOW IS FORECAST TO MOVE ACROSS
THE UPPER MIDWEST ON SUNDAY AS THE UPPER TROUGH CONTINUES TO DIG AND
SHIFT EAST INTO THE MIDWEST. THIS WILL BRING A COLD FRONT SOUTHEAST
ACROSS PORTIONS OF THE PLAINS AND MIDWEST. SOME SEVERE POTENTIAL
COULD DEVELOP ACROSS CENTRAL PORTIONS OF THE U.S. ON DAY 6/SUNDAY AS
THE COLD FRONT SWEEPS EASTWARD, BUT CONFIDENCE IS LOW GIVEN A LACK
OF DEEPER MOISTURE RETURN OVERLAPPING WITH STRONGER SHEAR ACROSS THE
MIDWEST.
AS THE UPPER TROUGH AND SURFACE COLD FRONT CONTINUE EAST ON DAY
7/MONDAY, SOME LOW-END SEVERE POTENTIAL COULD POSSIBLY DEVELOP
ACROSS THE MID-ATLANTIC TO THE SOUTHEAST, BUT CONFIDENCE IS LOW
GIVEN SIMILAR CONCERNS TO THOSE ON DAY 6/SUNDAY. WITH THIS SYSTEM
MOVING OFFSHORE BY THE END OF THE PERIOD, SEVERE POTENTIAL APPEARS
LOW ON DAY 8/TUESDAY.
