AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
800 AM CDT TUE JUN 9 2015

...SOUNDING DISCUSSION...

PRECIPITABLE WATER HAS CLIMBED UP TO ALMOST 2 INCHES THIS MORNING.
THERE WERE SEVERAL CLOUD LAYERS OBSERVED AT LAUNCH AND THE
SOUNDING SHOWS SEVERAL SATURATED LAYERS. THUNDERSTORMS ARE CURRENTLY
MOVING INTO OUR AREA. BASED OFF OF THE SOUNDING AND
CALCULATIONS...APPEARS THAT A BRIEF PERIOD OF HEAVY RAIN MAY BE
THE BIGGEST CONCERN THIS MORNING. WSR-88D DUAL POL ALGORITHMS
INDICATES 1-2 INCH PER HOUR RATES HAVE BEEN FALLING OVER PARTS OF
MARION...LAWRENCE...JEFFERSON DAVIS AND MARION MOVING SOUTHEAST
INTO OUR AREA. 0-6KM MEAN WIND IS 6 KNOTS SO STORMS COULD DROP A
QUICK INCH OR TWO AS THEY SLOWLY MOVE SOUTHEAST. AS HAS BEEN THE
CASE THE LAST FEW DAYS...WINDS ARE GENERALLY 10 KNOTS OR LESS IN
THE LOWER HALF OF THE ATMOSPHERE.

12Z BALLOON INFO: THERE WERE NO ISSUES WITH THE FLIGHT THIS
MORNING THAT LASTED 110 MINUTES. THE BALLOON ASCENDED TO 21.5
MILES ABOVE THE GROUND BEFORE BURSTING NEAR LAKE CATHERINE 18
MILES DOWNRANGE FROM THE OFFICE.

.PREV DISCUSSION... /ISSUED 356 AM CDT TUE JUN 9 2015/

SYNOPSIS...

UPPER RIDGE OVER THE RIO GRANDE VALLEY WITH THE AXIS OF AN UPPER
TROF FROM THE GREAT LAKES TO THE ALABAMA COAST. AT THE
SURFACE...HIGH PRESSURE CENTERED OFF THE ATLANTIC COAST WITH A
FRONTAL SYSTEM EXTENDING FROM LAKE ONTARIO TO THE RED RIVER
VALLEY. ISOLATED CONVECTION OVER THE COASTAL WATERS THIS MORNING.
ADDITIONAL CONVECTION OVER CENTRAL MISSISSIPPI NORTH OF INTERSTATE
20 IS SINKING TOWARD THE AREA. AWAY FROM MARINE
INFLUENCES...TEMPERATURES ARE IN THE MID 70S AT 3 AM.

SHORT TERM...

MOISTURE LEVELS CONTINUE TO INCREASE...WITH THE 09/00Z LIX
SOUNDING SHOWING A PRECIPITABLE WATER VALUE OF 1.86 INCHES. GFS
AND NAM BUFR SOUNDINGS HAVE BOTH INITIALIZED SOMEWHAT DRIER...IN
THE 1.65-1.70 RANGE. ALL MODEL SOLUTIONS KEEP MOISTURE LEVELS
RATHER HIGH...MOSTLY IN EXCESS OF 1.75 INCHES...THROUGH THE WORK
WEEK. UPPER IMPULSE MOVING SOUTHEAST FROM OKLAHOMA WILL REACH THE
AREA THIS AFTERNOON AND GRADUALLY CLOSE OFF A WEAK UPPER LOW NEAR
OR OVER THE AREA WEDNESDAY AND THURSDAY. HIGH MOISTURE LEVELS WILL
COMBINE WITH SOME UPPER DIVERGENCE TO ALLOW THE DEVELOPMENT OF
SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS TODAY WITH THE
POTENTIAL FOR LOCALLY HEAVY RAIN. WE LOSE THE UPPER DIVERGENCE FOR
WEDNESDAY AND THURSDAY...SO THINGS MAY NOT BE QUITE AS ACTIVE
FOR THOSE TWO DAYS. WILL BE CARRYING LIKELY POPS ACROSS MOST OF
THE AREA DURING THE DAYTIME PERIODS THROUGH THURSDAY...LOWERING TO
CHANCE OVERNIGHT. WILL NEED TO KEEP AN EYE ON RAINFALL TOTALS THE
NEXT FEW DAYS. HIGHER MOISTURE LEVELS...ADDITIONAL
CLOUDS...ETC...SHOULD HOLD HIGH TEMPERATURES IN THE MID AND UPPER
80S THROUGH THURSDAY. 35

LONG TERM...

UPPER RIDGING WILL BEGIN TO BUILD WESTWARD FROM THE ATLANTIC OVER
THE WEEKEND...GRADUALLY SHIFTING THE WEAK UPPER LOW WESTWARD. IT
MAY TAKE TILL THE MIDDLE OF NEXT WEEK FOR THE HIGH TO SHIFT FAR
ENOUGH WESTWARD TO CAP THE ATMOSPHERE...SO WILL ONLY SHOW A SLOW
DECLINE IN DAILY RAIN CHANCES. WILL MAINTAIN THE 50-60 DAYTIME POPS
ON FRIDAY...AND GRADUALLY TAPER DOWN TO 30 TO 40 PERCENT BY
TUESDAY. OVERNIGHT POPS WILL GENERALLY BE IN THE CHANCE CATEGORY.
OVERNIGHT LOWS WILL BE IN THE LOW TO MID 70S FOR MUCH OF THE
EXTENDED PERIOD. HIGHS WILL SLOWLY INCREASE AS RAIN CHANCES
DECREASE...RETURNING TO THE LOWER 90S BY ABOUT TUESDAY. 35

AVIATION...

VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGH MOST OF THIS MORNING
WITH THE EXCEPTION BEING NEAR ISOLATED TO SCATTERED SHRA/TSRA WHERE
TEMPO LOWER CIGS AND VSBYS WILL OCCUR. SHRA/TSRA WILL LIKELY START
TO BECOME SCATTERED TO NUMEROUS IN COVERAGE BY LATE MORNING OR EARLY
AFTERNOON AND CONTINUING MUCH OF THE AFTERNOON. PREVAILING MVFR
CONDITIONS ARE EXPECTED TO DEVELOP MAINLY DUE TO VSBY RESTRICTIONS
IN RAIN...AND TEMPO IFR MAY NEED TO BE ADDED WITH THE 12Z TAFS BASED
ON THE LATEST HI-RES MODELS AND RADAR TRENDS PROJECTION OF THE
TIMING OF HEAVIER RAINFALL FROM CONVECTION. SHRA/TSRA SHOULD
DECREASE IN COVERAGE AND IMPACTS TONIGHT...HOWEVER SOME AREAS OF
LIGHT FOG COULD BRING ADDITIONAL MVFR CATEGORY VSBYS. 22/TD

MARINE...

HIGH PRESSURE RIDGE OVER THE WESTERN ATLANTIC OCEAN INTO THE EASTERN
GULF COAST REGION WILL REMAIN NEARLY STATIONARY THROUGH THE WEEKEND.
SOUTHWEST WINDS THAT PICKED UP INTO THE 10 TO 15 KNOTS RANGE ACROSS
THE EASTERN WATERS OVERNIGHT SHOULD SETTLE BACK DOWN TO AROUND 10
KNOTS OR LESS ACROSS ALL WATERS THIS MORNING THROUGH WEDNESDAY SINCE
THE PRESSURE GRADIENT WILL BE SLACK.

WINDS AND SEAS ARE EXPECTED TO GRADUALLY RAMP UP WEDNESDAY NIGHT
INTO THURSDAY AND FRIDAY AS THE PRESSURE GRADIENT TIGHTENS DUE TO
STRENGTHENING HIGH PRESSURE TO THE EAST AND TENDENCY FOR LOWER
PRESSURE OVER THE SOUTHWEST AND FAR WESTERN GULF OF MEXICO.

CONDITIONS MAY APPROACH OR EXCEED SMALL CRAFT ADVISORY CRITERIA
THURSDAY NIGHT THROUGH FRIDAY NIGHT OR SATURDAY MORNING MAINLY OVER
THE WATERS 20 TO 60 NAUTICAL MILES OFFSHORE. 22/TD
