SPC AC 141622
DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1022 AM CST WED JAN 14 2009
VALID 151200Z - 161200Z
...NO TSTM AREAS FORECAST...
...SYNOPSIS...
MODELS INDICATE LITTLE CHANGE TO THE AMPLIFIED LARGE-SCALE UPPER
FLOW PATTERN THROUGH THIS FORECAST PERIOD. SHARP RIDGING IS
EXPECTED TO PERSIST ALONG OR JUST WEST OF PACIFIC COASTAL AREAS...
WHILE A DEEP COLD TROUGH ENCOMPASSES MUCH OF CANADA AND THE U.S.
EAST OF THE ROCKIES. THE LEADING FRONTAL ZONE ASSOCIATED WITH THE
EASTERN TROUGH MAY BECOME MORE DIFFUSE OVER THE SOUTHEAST GULF OF
MEXICO OR WESTERN CARIBBEAN...BUT A SIGNIFICANT REINFORCING
LOW-LEVEL COLD INTRUSION APPEARS LIKELY TO SURGE THROUGH MUCH OF THE
GULF OF MEXICO BY LATE THURSDAY/THURSDAY NIGHT. THIS WILL
CONTRIBUTE TO THE MAINTENANCE OF A DRY/STABLY STRATIFIED ENVIRONMENT
ACROSS MUCH OF THE U.S...AND NEGLIGIBLE POTENTIAL FOR THUNDERSTORM
ACTIVITY.
..KERR.. 01/14/2009
NOTE: THE NEXT DAY 2 OUTLOOK IS SCHEDULED BY 0700Z
