DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK

VALID 231200Z - 281200Z
..DISCUSSION
THE FORECAST PERIOD WILL BEGIN WITH A HIGHLY AMPLIFIED UPPER-AIR
PATTERN WITH A RIDGE OVER THE ROCKIES AND A DEEP TROUGH OVER THE
EASTERN US. BY THE MIDDLE OF THE NEXT WEEK, THIS MID-LEVEL FLOW
REGIME WILL TRANSITION TO ONE CHARACTERIZED AS BROADLY NORTHWEST
FLOW FROM THE PACIFIC NORTHWEST TOWARD THE SOUTHEAST UNITED STATES.
THIS FLOW REGIME WILL HELP DRIVE A MID-LEVEL TROUGH/SURFACE COLD
FRONT SOUTHEAST THROUGH THE PLAINS TOWARD THE END OF NEXT WEEK.
HOWEVER, LIMITED MOISTURE RETURN AHEAD OF THIS TROUGH/COLD FRONT
SHOULD TEMPER ANY SEVERE POTENTIAL.
THE FRONT IS EXPECTED TO PUSH SOUTH INTO AT LEAST THE NORTHERN GULF.
THIS RESULTING COLD/DRY AIR INTRUSION INTO THE NORTHERN GULF WILL
LIMIT THE POTENTIAL FOR APPRECIABLE MOISTURE RETURN AND SUBSEQUENT
THUNDERSTORM/SEVERE THUNDERSTORM POTENTIAL THROUGH THE REST OF THE
FORECAST PERIOD.
