AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
344 PM CST MON JAN 26 2015

.SHORT TERM...
A QUIET SHORT-TERM IN THE DEEP SOUTH WHILE THE NORTHEAST BRACES FOR
BLIZZARD CONDITIONS. TEMPERATURES DID MANAGE TO WARM A FEW DEGREES
WARMER THAN EXPECTED DUE TO DRYNESS OF THE AIR MASS. THE VERY
LARGE CIRCULATION FROM NOR`EASTER SYSTEM SHOULD MAINTAIN SOME WEAK
COLD AIR ADVECTION THIS FAR SOUTH FOLLOWED BY COLD HIGH SURGE FROM
THE GREAT LAKES REGION TUESDAY NIGHT. WENT ESSENTIALLY WITH MODEL
CONSENSUS ON TEMPERATURES.

.LONG TERM...
ANOTHER SURGE OF CANADIAN COLD AIR MOVES SOUTH FRIDAY WITH BULK OF
ADVECTION SHUNTING EAST. MEANWHILE...CUT-OFF LOW NEAR BAJA
CALIFORNIA WILL BE APPROACHING OVER THE WEEKEND TO INDUCE A STRONG
BUT SHORT-LIVED PERIOD OF RETURN FLOW SATURDAY EVENING AND SUNDAY.
THE MOISTURE FETCH WILL BE VERY LONG...GENERALLY FROM THE FLORIDA
STRAITS AND YUCATAN CONVERGING ONTO THE MOUTH OF THE MISSISSIPPI
RIVER FOR ENHANCED ONSHORE WINDS. THIS MAY RESULT IN HIGHER THAN
NORMAL TIDES AND COASTAL FLOOD CONSIDERATIONS FOR THE WEEKEND.
SOME ELEVATED CONVECTION MAY ALSO BE POSSIBLE BUT PRECEDANT COOL
AIR AND COOLING WATER TEMPERATURES MAY LIMIT INSTABILITY FOR
SEVERE WEATHER POTENTIAL OVER THE COASTAL WATERS AND NEAR THE
IMMEDIATE COAST SATURDAY EVENING AND EARLY SUNDAY. 24/RR

&&

.AVIATION...
VFR CONDITIONS ANTICIPATED THROUGH THE PERIOD. CANNOT TOTALLY RULE
OUT A BRIEF VISIBILITY RESTRICTION IN LIGHT FOG AT KMCB AROUND
SUNRISE TOMORROW...BUT THREAT NOT HIGH ENOUGH TO CARRY IN
FORECAST. 35


&&

.MARINE...
NORTHWESTERLY WINDS WILL LESSEN A BIT THROUGH TONIGHT THEN PICK UP
FOR A FEW HOURS TUESDAY MORNING WITH A SURGE RE-ENFORCEMENT AND
DRAINAGE ASPECTS. WINDS BECOME ONSHORE FOR THURSDAY BEFORE
SHIFTING AGAIN FRIDAY MORNING WITH STRONGER CANADIAN SURGE THOUGH
COLD AIR ADVECTION WILL BE LESS PRONOUNCED THAN WHAT WILL BE
SHUNTING EASTWARD. HIGH MODERATES SATURDAY WITH ONSHORE FLOW
DEVELOPING AND INCREASING TO STRONG LEVELS SATURDAY EVENING. SOME
TIDAL ISSUES MAY RESULT ALONG EAST-FACING SHORES SATURDAY EVENING
