PREV DISCUSSION... /ISSUED 302 PM CST WED JAN 2 2013/

SHORT TERM [TONIGHT THROUGH THURSDAY]...BROAD MOIST SOUTHWESTERLY
FLOW ALOFT WILL MAINTAIN CLOUDS AND PRECIPITATION CHANCES ACROSS MUCH
OF THE AREA THIS EVENING AS SURFACE COLD FRONT SAGS SOUTHWARD ACROSS
THE GULF. TO THE WEST...A MAIN UPPER TROUGH OVER THE CENTRAL CONUS
WILL CONTINUE TO DIG SLOWLY OVERNIGHT ALLOWING NEXT IMPULSE OF SHORT
WAVE ENERGY TO TRACK EASTWARD ACROSS THE DEEP SOUTH AND NORTHERN GULF
THROUGH TONIGHT. AHEAD OF THIS NEXT SYSTEM...INCREASED LIFT COMBINED
WITH THE SUFFICIENT MOISTURE IN PLACE WILL ALLOW FOR MORE WIDESPREAD
RAIN TO DEVELOP MOSTLY OVER THE NORTH CENTRAL GULF SHIFTING EAST AND
SOUTH THROUGH THURSDAY MORNING. THE PATTERN DOES NOT CHANGE MUCH FOR
THURSDAY WITH THE HIGHEST PRECIPITATION CHANCES EDGING EAST OF THE
I-65 CORRIDOR AND POINTS SOUTH ACROSS THE MARINE WATERS.
OTHERWISE...A LARGE RIDGE OF SURFACE HIGH PRESSURE CENTERED OVER THE
CENTRAL PLAINS WILL CONTINUE TO BUILD INTO THE TENNESSEE AND LOWER
MISSISSIPPI RIVER VALLEYS...WHICH WILL MAINTAIN A COOL NORTHERLY
SURFACE FLOW ACROSS OUR CWFA THROUGH THURSDAY AFTERNOON. HIGHS SHOULD
MOSTLY RANGE IN THE LOWER TO MID 50S ACROSS THE REGION. RAIN CHANCES
COME TO AN END LATE THURSDAY AFTERNOON INTO THURSDAY EVENING AS DRIER
AIR ALOFT SPREADS INTO THE REGION...AND THE MID LEVEL MOISTURE PLUME
BECOMES FOCUSED FARTHER TO SOUTH OVER THE GULF. DRY WEATHER IS
ANTICIPATED THURSDAY NIGHT...WITH SCATTERED BANDS OF MID/HIGH CLOUDS
ACROSS THE REGION. SURFACE RIDGING WILL CONTINUE TO BUILD ACROSS THE
DEEP SOUTH...WITH CHILLY READINGS EXPECTED EARLY FRIDAY MORNING. /01

LONG TERM [FRIDAY THROUGH TUESDAY]...AN UPPER LEVEL LOW ACROSS THE
SOUTHERN ROCKIES IS EXPECTED TO LIFT NORTHEASTWARD INTO THE CENTRAL
PLAINS AND UPPER MIDWEST BY THE END OF THE WEEK WHILE A PERSISTENT
SOUTHWEST FLOW PATTERN ALOFT WILL MAINTAIN ITSELF ACROSS THE GULF
COAST. IN ADDITION...LOW-LEVEL MOISTURE WILL BEGIN TO INCREASE BY THE
LATTER HALF OF THE WEEK. THE COMBINATION OF WHICH WILL INTRODUCE NEW
PRECIPITATION CHANCES SATURDAY AND SATURDAY NIGHT...WITH POPS
GENERALLY RANGING FROM 20 PERCENT ACROSS NORTHERN PORTIONS OF THE
CWFA...TO 30-40 PERCENT CLOSER TO THE COAST. RAIN CHANCES DECREASE BY
EARLY SUNDAY AS MUCH DRIER AIR IN THE DEEP LAYERS SPREAD ACROSS THE
REGION. DRY ZONAL FLOW SHOULD PREVAIL INTO EARLY NEXT WEEK...AND NO
RAIN IS EXPECTED MONDAY OR TUESDAY. OTHERWISE...THE COOL PARENT
SURFACE HIGH WILL BECOME CENTERED OVER THE TENNESSEE VALLEY
FRIDAY...WITH RIDGING HOLDING OVER THE GULF COAST INTO SATURDAY.
TEMPERATURES SHOULD REMAIN BELOW NORMAL FRIDAY AND SATURDAY.
TEMPERATURES SHOULD GRADUALLY MODERATE CLOSER TO SEASONAL NORMALS BY
EARLY NEXT WEEK. /01

AVIATION [02.18Z KMOB/KBFM AND KPNS TAF ISSUANCE]...A LARGE PLUME OF
CLOUDS OF VARYING LEVELS THIS AFTERNOON STREAMING OVER THE
SOUTHEASTERN QUARTER OF THE COUNTRY. THE LOWEST LEVELS PER UPSTREAM
OBSERVATIONS ARE IN THE IFR/MVFR RANGES AND THIS IS WHAT WILL BE
CARRIED IN THE FORECAST. PASSAGE OF -RA/RA AT TIMES. SURFACE HIGH
PRESSURE FROM TEXAS INTO THE OHIO RIVER VALLEY SUPPORTS A NORTHERLY
COMPONENT TO THE WIND...GENERALLY 5-10 KNOTS. /10

MARINE...SURFACE COLD FRONT SINKS DEEPER INTO THE GULF AS A LARGE
HIGH PRESSURE SYSTEM EXPANDS ACROSS THE CENTRAL GULF COAST TO CLOSE
OUT THE FIRST WEEK OF THE NEW YEAR. PASSAGE OF ENERGY...HIGH IN THE
ATMOSPHERE...IS SUPPORTIVE OF SCATTERED SHOWERS TONIGHT AND
THURSDAY...BECOMING BETTER FOCUSED DEEP INTO THE GULF LATE IN THE
WEEK CLOSER TO STALLING FRONTAL ZONE. EXPECT TO SEE A MODERATE
TO STRONG NORTH TO NORTHEAST FLOW OVER THE OPEN ALABAMA AND WESTERN
FLORIDA GULF WATERS THROUGH FRIDAY MORNING. WIND FORECAST SUPPORTS
POSTING CAUTIONARY HEADLINES FOR SMALLER MARINE CRAFT IN ZONES
650-655-670-675. GLOBAL GUIDANCE SHOWS A GENERAL 2 TO 4 FOOT RANGE
IN SEAS OUT TO 20 NAUTICAL MILES. 3 TO 5 FOOT RANGES 20-60 NAUTICAL
MILES OUT THROUGH FRIDAY WITH SOME HEIGHTS AROUND 6 FEET POSSIBLE AT
TIMES WHERE DURATION AND LONGER NORTHEAST FETCH LENGTH EXISTS. WINDS
DECREASE AND SEAS SUBSIDE LATE FRIDAY MORNING AS THE AXIS OF THE
HIGH PIVOTS ACROSS ALABAMA. AFTER A SHORT DURATION OF LIGHT EASTERLY
FLOW EARLY INTO THE WEEKEND WITH THE HIGH TO OUR NORTH MOVING
EASTWARD...A LIGHT NORTH TO NORTHEAST FLOW BECOMES REESTABLISHED
SUNDAY AND MONDAY AS A WAVE OF FRONTAL LOW PRESSURE MOVES EASTWARD
OVER THE CENTRAL GULF AND HIGH PRESSURE REBUILDS INTO THE LOWER
MISSISSIPPI RIVER VALLEY. NEXT RAIN CHANCE SATURDAY AND SATURDAY
NIGHT AS GULF FRONTAL LOW PASSES BY TO THE SOUTH. /10

FIRE WEATHER...NORTHERLY FLOW WILL PREVAIL THROUGH THE END OF THE
WEEK AS A SURFACE HIGH PRESSURE SYSTEM BUILDS FROM THE PLAINS INTO
THE LOWER MISSISSIPPI RIVER VALLEY. PRECIPITATION CHANCES SLOWLY
DECREASE THROUGH THE WEEK ONLY TO COME BACK UP AGAIN BY SATURDAY.
AS A RESULT...RELATIVE HUMIDITY VALUES LOOK TO STAY ABOVE CRITICAL
LEVELS THROUGH THE PERIOD. /01
