...SYNOPSIS...
A MID LEVEL TROUGH NOW DIGGING SEWD NEAR THE WA/ORE COASTS WILL
CONTINUE SSEWD AND EVOLVE INTO A CLOSED LOW OVER THE SRN GREAT BASIN
BY TUESDAY.  A COMBINATION OF STEEP LAPSE RATES AND ASCENT N OF THE
MID-UPPER JET WILL CONTRIBUTE TO WEAK INSTABILITY OVER NW NM AND NRN
AZ.  LOW-TOPPED THUNDERSTORMS MAY DEVELOP IN CONJUNCTION WITH
SURFACE HEATING OVER THE ELEVATED TERRAIN...THOUGH THUNDERSTORM
COVERAGE SHOULD REMAIN ISOLATED DUE TO MARGINAL INSTABILITY AND
LOW-MID LEVEL MOISTURE OVER THIS AREA.

ELSEWHERE...A CONTINENTAL POLAR AIR MASS ACROSS THE NRN AND ERN
CONUS WILL RESULT IN STABLE PROFILES AND PRECLUDE DEEP CONVECTION.
