PREV DISCUSSION... /ISSUED 400 AM CDT TUE OCT 21 2014/

SYNOPSIS...
A COOL AND QUIET NIGHT UNDERWAY WITH HIGH PRES SITTING OVER THE
REGION. A FEW HIGH CLOUDS WERE STREAMING ACRS THE AREA ON WLY FLOW
ALOFT WHILE WINDS IN THE LOWER LVLS WERE NELY. LATEST UA/WV
ANALYSIS SHOWS A SHORTWAVE DROPPING SE ACRS THE ERN CONUS AND THIS
WAS PUSHING A SWATH OF DRIER AIR TOWARD THE LOWER MS VALLEY.

DISCUSSION...
FEW CHANGES TO THE FCST FOR THE UPCOMING WEEK AS A GENERALLY DRY
AND QUIET WEATHER PATTERN REMAINS IN PLACE. A NARROW AMPLIFIED
RIDGE ALOFT WILL CROSS THE AREA TODAY AS THE UPPER LOW ASSOCIATED
WITH THE AFOREMENTIONED SHORTWAVE DIVES SOUTHEAST TOWARD THE E
COAST. MEANWHILE...A REINFORCING BOOST OF HIGH PRES AT THE SFC
CAN BE EXPECTED WEDNESDAY AS A COOL FRONT SLIDES S THROUGH THE
REGION. A WEAK SHORTWAVE WILL CROSS THE CNTL CONUS THURSDAY INTO
FRIDAY...BUT LITTLE MOISTURE WILL ACCOMPANY THE FEATURE AND THUS
DRY CONDITIONS ARE EXPECTED TO CONTINUE.

HIGH TEMPS ARE EXPECTED TO CLIMB INTO THE LOWER 80S THIS AFTN
WITH LOWS TONIGHT FALLING INTO THE MID 50S NORTH TO AROUND 60
SOUTH. TEMPERATURES WILL BE A FEW DEGREES COOLER WEDNESDAY AND
THURSDAY IN THE WAKE OF THE COOL FRONT...BUT OVERALL NO
SIGNIFICANT TEMPERATURE SWINGS ARE EXPECTED THROUGH THE WEEKEND.

A GRADUAL WARMING TREND WILL DEVELOP OVER THE WEEKEND INTO EARLY
NEXT WEEK AS RIDGING ALOFT BUILDS ACRS TX AND LA WHILE THE SFC
HIGH MOVES EAST ALLOWING FOR A RETURN OF LOW LVL MOISTURE. AT THIS
TIME...RAIN CHCS REMAIN MINIMAL THROUGH THE FCST PERIOD ALTHOUGH
AN APPROACHING FRONT COULD BRING A FEW SHOWERS BY THE MIDDLE OF
NEXT WEEK.

MARINE...
LT TO MODT OFFSHORE FLOW WILL PREVAIL THROUGH THE WEEK AS HIGH PRES
RIDGES S AND W ACRS LA AND E TX. A BRIEF PERIOD OF ELEVATED WINDS
AND SEAS...POSSIBLY REQUIRING EXERCISE CAUTION FLAGS...IS EXPECTED
WEDNESDAY AS THE PRES GRADIENT TIGHTENS BETWEEN THE HIGH TO THE
NORTH AND A DEVELOPING AREA OF LOWER PRES NR THE BAY OF CAMPECHE.
WINDS WILL DIMINISH THROUGH THE REMAINDER OF THE WEEK AS THE SFC
HIGH BUILDS SOUTH WHILE THE LOW OVER THE WRN GULF MOVES NE AWAY FM
THE AREA. AN ONSHORE FLOW WILL DEVELOP BY EARLY NEXT WEEK AS THE
SFC HIGH MOVES EAST OF THE AREA.
