AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
339 AM CST WED DEC 11 2013

.SHORT TERM TODAY THROUGH THURSDAY NIGHT...A 1031 MB SFC HIGH
CURRENTLY OVER THE TN VALLEY WILL QUICKLY MOVE EAST TO THE NORTH
CAROLINA COAST TODAY. HOWEVER...A STRONGER 1040MB SFC HIGH WILL
QUICKLY MOVE SOUTH OUT OF THE NORTHERN PLAINS AND INTO THE SOUTHERN
PLAINS EAST INTO THE TN VALLEY BY THURSDAY MORNING. THIS HIGH WILL
REINFORCE THE BELOW NORMAL TEMPERATURES ACROSS OUR AREA. HIGHS TODAY
ARE EXPECTED TO REACH THE UPPER 50S INLAND TO LOWER 60S ALONG THE
COAST. LOWS TONIGHT ARE A LITTLE UNCERTAIN. WE WILL HAVE A RETURN OF
LOW LEVEL COLD AIR ADVECTION...BUT AT THE SAME TIME WINDS WILL LIKELY
NOT DECOUPLE DUE TO A TIGHTER PRESSURE GRADIENT. IN ADDITION...SOME
HIGH LEVEL CLOUD COVER WILL ALSO MOVE THROUGH THE REGION AT TIMES.
THEREFORE...DID NOT GO AS LOW AS THE COLDEST MOS GUIDANCE FOR THE
TIME BEING. LOWS ARE STILL EXPECTED TO DROP TO AROUND 30 WELL INLAND
WITH MID TO UPPER 30S ALONG THE I-10 CORRIDOR. 34/JFB

LARGE SURFACE HIGH PRESSURE TO EXPAND ACROSS THE SOUTHEASTERN QUARTER
OF THE COUNTRY ON THURSDAY. NO RAIN FORECAST THURSDAY AND THURSDAY
NIGHT. DAYTIME HIGHS THURSDAY FROM THE MID 50S INTERIOR TO NEAR 60
OVER THE SOUTHERN ZONES WILL BE SOME 4 TO 8 DEGREES BELOW SEASONAL
FOR THE 12TH DAY OF DECEMBER. ALTHOUGH THERE WILL BE SOME INCREASE IN
HIGH LEVEL CLOUDS PUSHING IN FROM THE WEST THROUGH THE NIGHT...THESE
MAY BE THIN ENOUGH ALONG WITH LIGHT TO CALM WIND AND DEWPOINTS IN THE
MID TO UPPER 20S TO RESULT IN OVERNIGHT LOWS FALLING OFF INTO THE
UPPER 20S INTERIOR. 35 TO 40 CLOSER TO THE COAST. /10

.LONG TERM FRIDAY THROUGH TUESDAY...TO CLOSE OUT THE WEEK...SURFACE
HIGH OVER THE SOUTHEAST MOVES MORE EAST...TO OFF THE EAST COAST
WHILE A SURFACE LOW PRESSURE SYSTEM DEVELOPS OVER THE RED RIVER
VALLEY OF TEXAS/OKLAHOMA DURING THE DAY FRIDAY. CLOUDS INCREASING
WITH A MODERATING TREND FORECAST IN TEMPERATURES AS A
SOUTHEAST...RETURN FLOW EVOLVES. THIS BRINGS ABOUT SOME POTENTIAL OF
ADVECTIVE TYPE MARINE FOG FRIDAY NIGHT AND SATURDAY MORNING AS
WELL...AS DEWPOINTS AROUND 60 MOVE NORTHWARD ATOP COOLER WATER
TEMPERATURES OVER BAYS AND SOUNDS. GIVEN THIS POTENTIAL TO OCCUR OVER
3 DAYS OUT...WILL HOLD OFF MENTIONING FOG IN TEXT PRODUCTS...BUT
HIGHLIGHT RISK IN HAZARDOUS WEATHER OUTLOOK. DEEPER GULF MOISTURE
SLOWLY RECOVERS WITH PRECIPITABLE WATER VALUES MOVING TO  1.5 INCHES
BY FRIDAY NIGHT AS THE SURFACE LOW/ATTENDANT COLD FRONT ADVANCES INTO
THE LOWER MISSISSIPPI RIVER VALLEY AND AN INCREASE IN LOW LEVEL SOUTH
TO SOUTHWEST FLOW OPENS UP GULF MOISTURE. THE HIGHEST CHANCES OF
MEASUREABLE RAINS LOOK TO BE SPREADING FROM WEST TO EAST BY FRIDAY
NIGHT INTO SATURDAY AS LIFT BECOMES BETTER DEFINED WITH LOW PRESSURE
AND ASSOCIATED FRONT ADVANCING EAST INTO MISSISSIPPI AND ALABAMA. AN
ASSESSMENT OF INSTABILITY SUGGESTS THE PREDOMINANT MODE OF WEATHER
WILL BE SHOWERS WITH THIS SYSTEM WITH A SMALLER CHANCE OF THUNDER. AT
THIS TIME...IT APPEARS THE RISK FOR SEVERE WEATHER IS LOW. STAY
TUNED.

FRONT PUSHES EAST OF THE AREA BY SATURDAY NIGHT. HIGH PRESSURE
EXPANDS EASTWARD ACROSS THE SOUTHERN STATES SUNDAY AND WILL REMAIN
IN PLACE INTO THE FIRST OF NEXT WEEK. THE HIGH BRINGS A RAIN FREE
PATTERN SUNDAY THROUGH TUESDAY. OVERNIGHT LOWS BACK TO FREEZING OVER
THE INTERIOR MONDAY AND TUESDAY MORNINGS. DAYTIME HIGHS MID/UPPER 50S
INTERIOR TO LOWER 60S COAST SUNDAY/MONDAY TO RANGE FROM 63 TO 66 BY
TUESDAY. /10

&&

.AVIATION 11.12Z ISSUANCE...VFR CONDITIONS ARE EXPECTED THROUGH
THE TAF PERIOD. 34/JFB

&&

.MARINE...OFFSHORE FLOW WILL DIMINISH THROUGH THE DAY TODAY AS HIGH
PRESSURE OVER THE TN VALLEY WEAKENS AND MOVES EAST. ANOTHER STRONG
HIGH PRESSURE SYSTEM WILL BUILD SOUTH OUT OF THE PLAINS TONIGHT...
BRINGING A REINFORCING SURGE OF COLD AIR AND ALSO RESULTING IN A
TIGHTENING OF THE PRESSURE GRADIENT. THIS WILL BRING ANOTHER ROUND
OF MODERATE TO STRONG OFFSHORE FLOW TO THE MARINE AREA LATE TONIGHT
THROUGH THURSDAY. SMALL CRAFT ADVISORIES WILL LIKELY BECOME
NECESSARY FOR THURSDAY MORNING. THE HIGH WILL QUICKLY MOVE EAST INTO
THE WEST ATLANTIC BY FRIDAY AFTERNOON. MEANWHILE...A STORM SYSTEM
WILL BEGIN TO ORGANIZE OVER THE SOUTHERN PLAINS AND MOVE EAST. THIS
RESULTS IN WINDS VEERING TO A MODERATE ONSHORE FLOW BY FRIDAY
AFTERNOON. ANOTHER COLD FRONT MOVES THROUGH THE AREA SATURDAY NIGHT
WITH STRONG OFFSHORE FLOW RETURNING FOR THE END OF THE WEEKEND.
