   ...SYNOPSIS...
   THE CLOSED MID LEVEL LOW OVER NRN BAJA WILL BEGIN TO TRANSITION INTO
   AN OPEN WAVE AND MOVE EWD OVER NRN MEXICO BY FRIDAY NIGHT.  THE EWD
   MOTION OF THE BAJA LOW WILL OCCUR IN RESPONSE TO THE APPROACH OF
   ANOTHER TROUGH /NOW NEAR 145 W/ FROM THE ERN PAC...WHILE A SEPARATE
   NRN STREAM TROUGH WILL DIG SEWD TOWARD THE PAC NW COAST.  INCREASING
   WLY MID LEVEL FLOW OVER THE NRN ROCKIES WILL INDUCE LEE CYCLOGENESIS
   ACROSS THE CENTRAL/NRN HIGH PLAINS...WHILE THE APPROACH OF THE SRN
   STREAM TROUGH CONTRIBUTES TO PRESSURE FALLS AS FAR S AS W TX.  THE
   NET RESULT WILL BE INCREASING SLY FLOW/WAA ACROSS TX WHICH WILL HELP
   BREAK DOWN THE COASTAL TROUGH AND ALLOW LOW-LEVEL MOISTURE TO BEGIN
   SPREADING INLAND FROM THE WRN GULF LATE IN THE PERIOD. OTHERWISE...
   A BROAD TROUGH WILL PERSIST OVER NEW ENGLAND WITH AN ASSOCIATED
   CONTINENTAL POLAR AIR MASS FROM THE UPPER MS VALLEY TO NEW ENGLAND.
   
   ISOLATED THUNDERSTORMS WILL BE POSSIBLE ACROSS SRN AZ DURING THE
   DAY...AND THIS ACTIVITY WILL LIKELY DEVELOP EWD TOWARD SRN NM AND SW
   TX TOMORROW NIGHT AS THE MID LEVEL LOW AND REGION OF RICHEST MID
   LEVEL MOISTURE SPREAD EWD/ENEWD.  A SEPARATE SWATH OF SLIGHTLY
   ELEVATED CONVECTION MAY ALSO DEVELOP FRIDAY NIGHT INVOF THE
   MIDDLE/UPPER TX COAST. CONVECTION ACROSS THIS AREA WILL BE
   SUPPORTED BY INCREASING LOW-LEVEL MOISTURE ON A STRENGTHENING
   LOW-LEVEL JET...THOUGH INSTABILITY WILL LIKELY REMAIN TOO MARGINAL
   FOR ANY THREAT OF SEVERE STORMS.
