...SYNOPSIS...
POSITIVELY-TILTED UPPER TROUGH EXTENDS FROM CNTRL ONTARIO SWWD

THE NRN BAJA PENINSULA. THE UPPER TROUGH WILL SHIFT EWD AS A STRONG
UPPER RIDGE PROGRESSES EWD OVER THE INTERMOUNTAIN WEST...RESULTING
IN AN AMPLIFIED PATTERN OVER THE WRN CONUS BY THE END OF PERIOD.
DEEP SWLY FLOW WILL BE MAINTAINED FROM THE SWRN STATES TO THE
ATLANTIC COAST.

AT THE SURFACE...COOL TEMPERATURES AND MEAGER MOISTURE BENEATH AN
EXPANSIVE AREA OF HIGH PRESSURE COVER MOST OF THE COUNTRY. A FEW
SHOWERS ARE POSSIBLE ACROSS THE TX COASTAL BEND AND SRN LA AS A WEAK
SHORTWAVE TROUGH MOVES NEWD IN THE SWLY FLOW ALOFT. A FEW SHOWERS
ARE ALSO POSSIBLE ALONG A WEAK FRONTAL BOUNDARY ACROSS SE GA AND NRN
FL. HOWEVER...INSTABILITY OVER BOTH AREAS WILL BE LIMITED BY
RELATIVELY WARM TEMPERATURES ALOFT AND NO TSTMS ARE EXPECTED.
