DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0351 AM CDT SUN AUG 17 2008
VALID 201200Z - 251200Z
...DISCUSSION...
LARGE SCALE PATTERN MAY BECOME MORE SUPPORTIVE OF ORGANIZED SEVERE
THUNDERSTORM DEVELOPMENT ACROSS THE NCNTRL U.S. DURING THE DAY5-6
TIME FRAME. BOTH THE GFS AND ECMWF INDICATE A STRONG UPPER TROUGH
WILL PROGRESS ACROSS THE NRN ROCKIES INTO THE NRN PLAINS DURING THE
LATTER PART OF THE WEEK. THIS FEATURE WILL FORCE A SHARP COLD FRONT
ACROSS THE DAKOTAS INTO MN WHERE IT WILL ENCOUNTER A MARGINALLY
MOIST BOUNDARY LAYER ENVIRONMENT...DEW POINTS MAY STRUGGLE TO RISE
INTO THE 60S UNTIL VERY LATE IN THE WEEK. GIVEN THE MEAGER MOISTURE
RETURN AHEAD OF THIS SYSTEM...AT LEAST INITIALLY...ORGANIZED SEVERE
CONVECTION WILL NOT BE OUTLOOKED AT THIS TIME.
SEVERE WEATHER WILL BE WANING ACROSS THE SERN U.S. AS STRONGER SHEAR
ASSOCIATED WITH FAY WILL LIKELY BE SHUNTED OFFSHORE BY THE END OF
THE WEEK.
