DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0347 AM CDT SAT SEP 20 2014

VALID 231200Z - 281200Z

...DISCUSSION...
MEDIUM-RANGE MODELS/ENSEMBLES ARE IN GOOD GENERAL AGREEMENT WITH
SUGGESTIONS OF AN INCREASINGLY AMPLIFIED PATTERN BY THE MIDDLE/LATE
PART OF NEXT WEEK. THIS WILL BE HIGHLIGHTED BY A PROMINENT
EASTWARD-MOVING TROUGH OVER THE WESTERN CONUS LATE IN THE WEEK.

ON DAY 4/TUESDAY...A FEW STRONG STORMS MAY BE POSSIBLE ACROSS THE
CENTRAL HIGH PLAINS IN ASSOCIATION WITH A SLOW-MOVING UPPER LOW.
THEREAFTER...AS SURFACE HIGH PRESSURE/DRY CONDITIONS PREVAIL OVER
THE EASTERN HALF OF THE CONUS...MODEST MOISTURE AND A LACK OF
STRONGER FORCING/VERTICAL SHEAR ARE EXPECTED TO PRECLUDE AN
APPRECIABLE SEVERE RISK.
