Area forecast discussion, Jan 29, 3:41 AM CST, 1 hour 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
341 AM CST SUN JAN 29 2012

.SHORT TERM...
TRANQUIL CONDITIONS WILL PREVAIL ACROSS THE FORECAST AREA IN THE
SHORT TERM. HIGH PRESSURE OVER THE REGION TODAY WILL SHIFT TO THE EAST
TONIGHT AND MONDAY...ALLOWING FOR A RETURN OF A SOUTHEASTERLY FLOW
OF AIR AND MODERATING TEMPERATURES FOR THE BEGINNING OR THE WORK
WEEK. A BROAD UPPER TROUGH OVER THE EASTERN CONUS WILL MOVE OFF
THE COAST TONIGHT WITH A TRANSITION TO A MORE ZONAL OR WEST SOUTHWEST
FLOW ALOFT FOR THE FIRST HALF OF THE WORK WEEK. 11

.LONG TERM...
A SHORT WAVE TROUGH IN THE SOUTHERN STREAM WILL MOVE ACROSS
NORTHERN MEXICO AND SOUTHERN TEXAS AND THEN DAMPEN OUT AS IT MOVES
ACROSS THE GULF COAST REGION MONDAY NIGHT INTO TUESDAY. THIS
FEATURE WILL LIKELY BRING AN INCREASE IN CLOUD COVER...BUT LITTLE
IN THE WAY OF RAIN AS LOW LEVEL MOISTURE WILL STILL BE LACKING.
BETTER CHANCES FOR CONVECTION WILL BE IN THE OFFING WEDNESDAY AND
THURSDAY. ON WEDNESDAY AND WEDNESDAY NIGHT...A QUICK MOVING SHORT
WAVE TROUGH IN THE NORTHERN STREAM WILL MOVE FROM THE CENTRAL CONUS
AND ACROSS THE GREAT LAKES AND OHIO VALLEY REGIONS PUSHING A COLD
FRONT INTO THE SOUTHERN STATES. LIFT ASSOCIATED WITH THIS ALONG
WITH DEEPENING MOISTURE AND INSTABILITY WILL LEAD TO SCATTERED
SHOWERS AND THUNDERSTORMS. ANOTHER SHORT WAVE TROUGH MOVING OUT OF
THE NORTHWEST AT MID WEEK IS FORECAST TO DIVE SOUTHEAST INTO THE
CENTRAL CONUS AND EVOLVE INTO A FAIRLY DEEP TROUGH ACROSS THE
EASTERN U.S. FOR THE END OF THE WEEK. THIS WILL AGAIN BRING
SCATTERED CONVECTION TO THE FORECAST AREA THURSDAY AND THURSDAY
NIGHT WITH A COLD FRONT EXPECTED TO THEN PUSH THROUGH THE AREA
ABOUT LATE THURSDAY NIGHT INTO FRIDAY...ALTHOUGH THERE ARE SOME
TIMING DIFFERENCES BETWEEN THE VARIOUS MODELS. COLDER CONDITIONS
WILL THEN RETURN TO THE FORECAST AREA FOR NEXT WEEKEND. 11

&&

.AVIATION...
STRONG NORTHERLY WINDS TRANSPORTING ACROSS LAKE PONTCHARTRAIN WILL
CONTINUE TO PRODUCE WINDS IN EXCESS OF 12 KNOTS AT KMSY AND KNEW
THROUGH 15Z. WINDS WILL DECREASE AFTER 15Z...AS BOUNDARY LAYER WINDS
ALOFT BEGIN TO WEAKEN FOR THOSE TERMINALS. ALL OTHERS WILL REMAIN
LIGHT WITH NORTHEASTERLY WINDS. OTHERWISE...CLEAR SKIES AND GOOD
VISIBILITIES ARE EXPECTED AT ALL TERMINALS.

MEFFER

&&

.MARINE...
STRONG HIGH PRESSURE BUILDING IN ALONG WITH COLD AIR ADVECTION
CONTINUES TO KEEP WINDS ELEVATED. THESE SMALL CRAFT WINDS WILL
QUICKLY FALL OFF THIS MORNING AS THE CENTER OF THE RIDGE MOVES CLOSE
TO THE AREA AND WEAKENS THE PRESSURE GRADIENT. SO...WILL ALLOW THE
ADVISORY TO EXPIRE MID MORNING AS PREVIOUSLY FORECAST. THE SURFACE
HIGH WILL STEADILY MOVE EAST INTO THE ATLANTIC. THIS WILL ALLOW
WINDS TO ROTATE FROM NORTHEAST TODAY TO EAST AND THEN SOUTHEAST
LATER ON MONDAY. LIGHTER ONSHORE FLOW TO PERSIST UNTIL NEXT FRONTAL
BOUNDARY AT THE END OF THIS WEEK. THOUGH MODEL SOLUTIONS HAVE NOT
BEEN PARTICULARLY CONSISTENT...HAVE GONE WITH EARLY FRIDAY MORNING
FROPA IN THE COASTAL WATERS PER GFS.
