DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK

VALID 281200Z - 291200Z

...NO TSTM AREAS FORECAST...

...SUMMARY...
THE RISK FOR THUNDERSTORMS STILL APPEARS NEGLIGIBLE ACROSS THE U.S.
WEDNESDAY THROUGH WEDNESDAY NIGHT.

...SYNOPSIS...
THE REMNANTS OF A CLOSED LOW...WITHIN A BELT OF WESTERLIES EMERGING
FROM THE SUBTROPICAL EASTERN PACIFIC...ARE FORECAST TO REACH THE
WYOMING/COLORADO ROCKIES BY 12Z WEDNESDAY...BEFORE BEING FORCED
SOUTHEASTWARD THEN EASTWARD TOWARD THE LOWER OHIO VALLEY THROUGH THE
REMAINDER OF THE PERIOD.  AS THIS OCCURS...MODELS INDICATE
SUBSTANTIVE MOISTENING WITHIN A SOUTH/SOUTHWESTERLY LOWER/MID
TROPOSPHERIC STREAM AHEAD OF IT...WHICH COULD CONTRIBUTE TO VERY
WEAK DESTABILIZATION BASED WITHIN THE 850-700 MB LAYER...ACROSS
PARTS OF THE OZARK PLATEAU INTO THE LOWER OHIO VALLEY BY WEDNESDAY
EVENING.  AIDED BY FORCING FOR ASCENT ASSOCIATED WITH THE MID-LEVEL
IMPULSE...THIS PROBABLY WILL BE ACCOMPANIED BY A BAND OR BANDS OF
SHOWERS...BUT FORECAST SOUNDINGS...IN GENERAL...STILL DO NOT
INDICATE THAT THERMODYNAMIC PROFILES WILL BECOME SUPPORTIVE OF AN
APPRECIABLE RISK FOR THUNDERSTORM ACTIVITY.

OTHERWISE...LARGE-SCALE PATTERN DEVELOPMENTS ARE EXPECTED TO
MAINTAIN GENERALLY STABLE CONDITIONS AND LOW CONVECTIVE POTENTIAL
ELSEWHERE ACROSS THE NATION.
