DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0330 AM CST MON JAN 13 2014

VALID 161200Z - 211200Z

...DISCUSSION...
LARGE-SCALE UPPER FLOW EVOLUTION BY LATE NEXT WEEKEND INTO EARLY
NEXT WEEK REMAINS UNCLEAR...BUT THE LATEST MEDIUM RANGE MODELS ARE
MORE SUGGESTIVE OF LITTLE CHANGE TO GENERAL EASTERN PACIFIC/WESTERN
NORTH AMERICAN RIDGING AND CENTRAL/EASTERN NORTH AMERICAN TROUGHING.
IT APPEARS POSSIBLE THAT THE PATTERN MAY BECOME A BIT LESS AMPLIFIED
COMPARED THAT OF THE MIDDLE TO LATTER PORTION OF THIS
WEEK...PARTICULARLY ACROSS PARTS OF THE EASTERN UNITED STATES.
HOWEVER...GUIDANCE SUGGESTS LITTLE POTENTIAL FOR EITHER
SUSTAINED/SUBSTANTIVE BOUNDARY LAYER MOISTENING ACROSS THE
NORTHERN/WESTERN GULF OF MEXICO AND WATERS OFF THE ATLANTIC
SEABOARD...OR THE DEVELOPMENT OF A SUSTAINED SOUTHERLY RETURN FLOW.
AS A RESULT...DRY AND GENERALLY STABLE CONDITIONS PROBABLY WILL
CONTINUE EAST OF THE ROCKIES...AS WELL AS ACROSS THE WEST...WITH LOW
CONVECTIVE POTENTIAL.
