..DISCUSSION...
UPPER LOW FORECAST OVER THE FOUR CORNERS AREA AT THE START OF THE
PERIOD WILL MOVE PROGRESSIVELY EWD ACROSS THE S CENTRAL/SERN CONUS
THROUGH DAY 6 /WED. APR. 18/ WHILE WEAKENING SLOWLY. THOUGH AN
ASSOCIATED SURFACE LOW WILL MOVE INTO THE SRN PLAINS FOR DAY 4 /MON.
APR. 16/...PREVIOUS COLD AIR SURGE INTO THE GULF SHOULD HINDER
FAVORABLE MOISTURE RETURN INTO THE PLAINS FOR A SIGNIFICANT SEVERE
EVENT. WITH THE SYSTEM THEN WEAKENING THROUGH MID-WEEK...SEVERE
PROBABILITIES SHOULD REMAIN LIMITED.
THE NEXT SYSTEM OF INTEREST SHOULD BEGIN AFFECTING THE PLAINS IN THE
DAYS 7-8 TIME FRAME /I.E. THU. APR. 19 TO FRI. APR. 20/.
HOWEVER...MODELS DIFFER GREATLY IN THE INTENSITY OF THIS SYSTEM --
AND THUS THE POTENTIAL FOR ADEQUATE MOISTURE RETURN INTO THE CENTRAL
CONUS. THEREFORE...IT APPEARS THAT OVERALL THE POTENTIAL FOR A
SIGNIFICANT SEVERE WEATHER EVENT THROUGH DAY 8 REMAINS LOW ATTM.
