130W.

..DISCUSSION...
W OF 110W...
SIGNIFICANT CHANGES IN THE OVERALL PATTERN FROM 24 HOURS AGO
IN THIS REGION. BROAD UPPER LEVEL RIDGE WITH AXIS ALONG 122W
IS SHIFTING EWD 15-20 KT WITH ASSOCIATED ANTICYCLONIC CENTER
NEAR 13N121W. FLOW TO THE SW OF THE ANTICYCLONE IS STRONGLY
DIFFLUENT WHICH IS ENHANCING CONVECTION ALONG ITCZ AXIS BETWEEN
125W AND 130W. CYCLONIC CIRCULATION CENTER NEAR 27N141W AND
ASSOCIATED TROUGH AXIS SW TO 19N143W IS MOVING INTO THE
DISCUSSION AREA WITH SOME MID/UPPER LEVEL DRY AIR SWEEPING
AROUND THE E SIDE OF THE TROUGH AND OVER THE AREA N OF 20N W OF
138W. A COLD FRONT WAS ENTERING THE FAR WRN PORTION OF THE
DISCUSSION AREA N OF 25N. UPPER LEVEL JET PUNCHES NEWD FROM
23N137W 30N125W AND TURNS MORE EASTWARD ALONG THE U.S. MEXICO
BORDER TO THE SW CONUS. JET IS TRANSPORTING VAST AMOUNTS OF DEEP
LAYERED MOISTURE TO A MAJOR WINTER STORM IN PROGRESS OVER THE

DESCRIBED ABOVE. ELSEWHERE OVER THE AREA MODERATE TO VERY STRONG
SUBSIDENCE COVERS CENTRAL MEXICO AND CENTRAL AMERICA SUPPRESSING
ANY CONVECTION ALONG THE ITCZ. AT THE SURFACE...WIND FLOW ACROSS
CENTRAL AMERICA FUNNELING MODERATE TO STRONG WINDS ACROSS
PANAMA...PAPAGAYO...FONSECA AND TEHUANTEPEC GAPS WITH SOME ROUGH
