DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0105 AM CST WED JAN 26 2011

VALID 281200Z - 291200Z

...SYNOPSIS...
MODELS INDICATE LITTLE CHANGE TO THE GENERAL LARGE-SCALE PATTERN FOR
THURSDAY INTO FRIDAY. WITHIN THE SOUTHERN BRANCH OF THE PREVAILING
SPLIT UPPER FLOW...A CLOSED LOW/TROUGH MAY GRADUALLY SHIFT EAST OF
BAJA INTO THE NORTHWESTERN MEXICAN PLATEAU...AND THE CENTER OF A
DOWNSTREAM SURFACE RIDGE MAY BEGIN RETREATING EASTWARD ACROSS THE
GULF OF MEXICO. HOWEVER...GUIDANCE SUGGESTS THAT A SUBSTANTIVE
RETURN FLOW OF MOISTURE TO THE LOWER RIO GRANDE VALLEY AND WESTERN
GULF COAST IS UNLIKELY...WITH LITTLE POTENTIAL FOR SIGNIFICANT GULF
OF MEXICO BOUNDARY LAYER MOISTENING THROUGH THIS PERIOD. AS A
RESULT...STABLE CONDITIONS WITH NEGLIGIBLE CONVECTIVE POTENTIAL
SHOULD PERSIST ACROSS THE SOUTH CENTRAL STATES...AS WELL AS THE
REMAINDER OF THE NATION.
