DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0226 AM CDT TUE SEP 23 2014

VALID 251200Z - 261200Z

...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
THUNDERSTORMS WILL BE POSSIBLE THURSDAY ACROSS AREAS SUCH AS THE
COASTAL SOUTHEAST UNITED STATES...THE SOUTHERN ROCKIES...AND THE
PACIFIC NORTHWEST. LITTLE OR NO RISK FOR SEVERE WEATHER IS
ANTICIPATED THURSDAY.

...DISCUSSION...
AS AN AMPLIFIED LONGWAVE PATTERN PERSISTS...THE MOST CONSEQUENTIAL
FEATURES OF NOTE ON THURSDAY WILL BE AN EAST-NORTHEASTWARD ADVANCING
UPPER TROUGH/POLAR JET OVER THE WEST COAST AND NORTHERN
INTERMOUNTAIN REGION. ALTHOUGH BUOYANCY WILL BE WEAK...THIS SCENARIO
MAY CONTRIBUTE TO SOME THUNDERSTORMS ACROSS PARTS OF THE PACIFIC
NORTHWEST/NORTHERN INTERMOUNTAIN REGION.

EAST OF THE ROCKIES...MULTIPLE SLOW-MOVING UPPER LOWS WILL
OVERSPREAD AREAS SUCH AS THE PLAINS AND SOUTHEAST STATES ON THE
PERIPHERY OF A MIDWEST-CENTERED UPPER RIDGE. SOME THUNDERSTORMS WILL
BE POSSIBLE ACROSS THE SOUTH-CENTRAL HIGH PLAINS/SOUTHERN ROCKIES AS
WELL AS THE COASTAL SOUTHEAST CONUS. HOWEVER...NO SEVERE
THUNDERSTORMS ARE EXPECTED GIVEN A RELATIVE LACK OF
BUOYANCY/VERTICAL SHEAR.
