DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1158 PM CST MON DEC 05 2016

VALID 071200Z - 081200Z

...NO TSTM AREAS FORECAST...

...SUMMARY...
THUNDERSTORMS ARE NOT ACROSS THE CONTIGUOUS U.S. ON WEDNESDAY.

...SYNOPSIS...
A LARGE-SCALE TROUGH WILL SHIFT EASTWARD ACROSS THE NORTHERN AND
CENTRAL PLAINS WEDNESDAY...REACHING THE MID-MISSISSIPPI VALLEY AND
UPPER GREAT LAKES REGION BY 12Z THURSDAY MORNING.  AT THE SURFACE...A
LARGE ARCTIC HIGH PRESSURE AREA WILL ADVANCE RAPIDLY TO THE SOUTH
AND SOUTHEAST THROUGH THE PLAINS AND ALSO REACH THE OHIO TO LOWER
MISSISSIPPI VALLEYS LATE IN THE FORECAST PERIOD.  A PRECEDING COLD
FRONT MOVING EQUATORWARD THROUGH THE GULF BASIN DURING DAY 1 WILL
LIMIT THE RETURN OF SUFFICIENT MOISTURE INTO THE NORTHWEST GULF
COAST AREA ON WEDNESDAY AHEAD OF THE ARCTIC FRONT.  FORECAST
SOUNDINGS CONTINUE TO SUGGEST SHALLOW ELEVATED CONVECTION MAY
DEVELOP WITHIN THE SOUTHWARD-ADVANCING FRONTAL ZONE FROM THE LOWER
MISSISSIPPI VALLEY TO SOUTHEAST TEXAS.  HOWEVER...THE UNSTABLE LAYER
IS NOT EXPECTED TO BECOME DEEP ENOUGH TO SUPPORT THUNDERSTORMS.
