AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
1058 AM CDT TUE APR 8 2014

.UPDATE...

UPDATED POP AND WEATHER GRIDS FOR FIRST PERIOD TO ACCOMODATE
PRECIPITATION REACHING THE AREA AHEAD OF SCHEDULE. TROF AXIS WAS
NEAR THE TEXAS-LOUISIANA BORDER AT 12Z. GENERALLY SCATTERED POPS
FOR THE REST OF THE DAY WITH MENTION OF SMALL HAIL AND GUSTY WINDS
PER EARLIER DISCUSSION. 35

&&

.PREV DISCUSSION... /ISSUED 434 AM CDT TUE APR 8 2014/

SHORT TERM...

MAIN CONCERNS WILL BE REGARDING THE PASSAGE OF A SHARP TROUGH AXIS
WITH A PRONOUNCED JET STRUCTURE MOVING ACROSS THE FORECAST AREA
TODAY. LIFT PROVIDED BY COUPLED JETS IN A SHARPLY CYCLONICALLY CURVED
ORIENTATION WILL GENERATE STRONG OMEGA AROUND 18Z TODAY.
MEANWHILE...THE PROXIMITY TO DIGGING JET MAXIMUM INTO THE BASE OF
THE TROUGH WILL PRODUCE A STRATOSPHERIC INTRUSION OF HIGH EQUIVALENT
POTENTIAL VORTICITY WELL INTO THE TROPOSPHERE. THIS TYPICALLY CAUSES
ENHANCED GUSTINESS INTO THE LOWER NEAR SURFACE LAYERS THAT CAN BE
DOUBLED THE PREVAILING WINDS. VERY COLD TEMPERATURES ALOFT WITH A
STEEP LAPSE RATE...HIGHLIGHTED WITH ADVECTION OF -24C AIR AT H50
WILL BE CONDUCIVE FOR HAIL DEVELOPMENT AND DOWNWARD TRANSPORT OF
SOME OF THE STRATOSPHERIC FLAVORED WINDS THAT CAN APPROACH SEVERE
LEVELS AS DOWNBURSTS UNDER THE CELLS.

LOCAL CHAP ASSESSMENT USING THE GFS MODEL SOUNDING AT 18Z DID
INDICATE A 9 PERCENT CHANCE OF SEVERE...SLIGHTLY HIGHER THAN THE 5
PERCENT INDICATIONS BY SPC...FORECAST HAIL SIZE 0.35-0.50"
/PEA-MARBLE/...GUST POTENTIAL 43KT/49 MPH. THESE VALUES WILL BE USED
AS BASIS FOR HAZARDOUS WEATHER OUTLOOK. MAIN IMPACT PERIOD WILL BE
BETWEEN 17Z-01Z TODAY DURING DAYTIME HEATING AND SHOULD BE LIMITED
TO AREAS PRIMARILY EAST OF I-55 CORRIDOR...WHICH SHOULD BE JUST EAST
OF THE TROUGH AXIS BY THAT TIME. CELL MOVEMENTS WILL LIKELY BE FROM
NW TO SE AROUND 35 KT. COVERAGE WILL BE HIGHLY CELLULAR AND
SCATTERED. TEMPERATURES WILL THEN SETTLE TO BELOW NORMAL LEVELS WITH
40S IN THE INTERIOR AND NON-MARINE INFLUENCED AREAS. 24/RR

LONG TERM...

THE MEDIUM RANGE GUIDANCE IS FAIRLY GOOD AGREEMENT ON THURSDAY AND
FRIDAY...AND HAVE NOT MADE ANY SIGNIFICANT CHANGES TO THE ONGOING
FORECAST DURING THIS PERIOD. STRONG AND DEEP RIDGING WILL DOMINATE
THE GULF SOUTH...RESULTING IN CLEAR SKIES AND LOW HUMIDITIES.
DUE TO THE DRIER THAN NORMAL AIRMASS IN PLACE...THE DIURNAL RANGE
WILL BE LARGER THAN NORMAL. WEDNESDAY NIGHT WILL SEE A LINGERING
COLD POOL ASSOCIATED WITH A DEPARTING UPPER LEVEL TROUGH AXIS
REMAIN OVER THE AREA. AS A RESULT...OVERNIGHT LOWS WILL COOL INTO
THE LOWER TO MIDDLE 40S OVER MOST INLAND AREAS. CLOSER TO THE
COAST AND SOUTH OF THE TIDAL LAKES...SOME MODERATION IN THE
TEMPERATURES IS EXPECTED WITH LOWS ONLY DIPPING TO NEAR 50
DEGREES. WITH STRONG SUBSIDENCE IN PLACE ALOFT...DAYTIME HIGHS
WILL QUICKLY RECOVER AND WILL RISE TO MORE NORMAL READINGS IN THE
MIDDLE TO UPPER 70S ON THURSDAY AND FRIDAY. OVERNIGHT LOWS WILL
MODERATE A BIT THURSDAY NIGHT AS 925MB TEMPERATURES WARM. AS A
RESULT...OVERNIGHT LOWS WILL ONLY COOL INTO THE LOWER TO MIDDLE
50S OVER MOST OF THE REGION.

HEADING INTO SATURDAY AND SUNDAY...SOME MODEL DIFFERENCES BEGIN TO
ARISE. THE 500MB PATTERN ON THE 00Z RUN OF THE EURO IS SLIGHTLY
MORE AMPLIFIED...WITH A STRONGER UPPER LEVEL RIDGE INDICATED OVER
THE AREA ON SATURDAY.  THE GFS RUN HAS A MUCH WEAKER RIDGE IN
PLACE. HAVE WENT WITH A BLEND OF THE SOLUTIONS FOR THE WEEKEND.
GIVEN THIS...AS THE RIDGE AXIS SHIFTS EASTWARD DURING THE PERIOD
MOISTURE ADVECTION WILL TAKE HOLD. THIS INCREASED MOISTURE
COMBINED WITH AN ELEVATED INVERSION WILL LEAD TO SOME LOW STRATUS
FORMING DURING THE OVERNIGHT HOURS WHICH WILL THEN MIX OUT TO A
STRATO-CU FIELD DURING THE AFTERNOON HOURS. TEMPERATURES WILL BE
NEAR TO SLIGHTLY WARMER THAN AVERAGE BOTH DAYS...WITH HIGHS
CLIMBING INTO THE UPPER 70S AND LOWER 80S AND OVERNIGHT LOWS
COOLING INTO THE UPPER 50S AND LOWER 60S.

LATE SUNDAY...HAVE PUT IN SOME SLIGHT CHANCE POPS FOR THE WESTERN
THIRD OF THE FORECAST AREA IN RESPONSE TO SOME INCREASED PVA AND
OVERALL FORCING IN ADVANCE OF AN APPROACHING UPPER LEVEL TROUGH.
UNFORTUNATELY...THERE ARE SOME SIGNIFICANT TIMING DIFFERENCES
SUNDAY NIGHT AND MONDAY BETWEEN THE EURO AND THE GFS. THE EURO
DEPICTS A MUCH MORE PROGRESSIVE OVERALL SOLUTION WITH A NEGATIVELY
TILTED TROUGH KICKING THROUGH THE AREA SUNDAY NIGHT. A SECONDARY
UPPER LEVEL TROUGH DESCENDING FROM THE NORTHERN STREAM WILL THEN
BEGIN TO IMPACT THE REGION LATE MONDAY. THE GFS IS SLOWER WITH THE
INITIAL TROUGH...AS IT FEELS THE INFLUENCE OF THE NORTHERN STREAM
ENERGY DESCENDING THROUGH THE ROCKIES MUCH MORE STRONGLY. AS A
RESULT...THE INITIAL TROUGH MERGES WITH THE NORTHERN STREAM ENERGY
TO FORM ON LARGER LONGWAVE TROUGH THAT MARCHES THROUGH THE AREA
MONDAY INTO MONDAY NIGHT. HAVE DECIDED TO GO WITH A BLEND THAT
EMPHASIZES THE EURO SOLUTION GIVEN THE PROGRESSIVE NATURE OF THE
PACIFIC BASED TROUGHS THIS SPRING SEASON. CHANCE POPS ARE IN PLACE
SUNDAY NIGHT AND MONDAY...WITH LINGERING SLIGHT CHANCE POPS INTO
MONDAY NIGHT. TEMPERATURES WILL BE COOLER ON MONDAY IN THE WAKE OF
THE INITIAL TROUGH...WITH HIGHS DROPPING INTO THE LOWER TO MIDDLE
70S. HOWEVER...THE STRONGER SHOT OF COLDER AIR WILL FEED INTO THE
AREA MONDAY NIGHT AND TUESDAY IN THE WAKE OF THE SECOND AND MUCH
STRONGER NORTHERN STREAM TROUGH AXIS.  32/PG

AVIATION...

VFR CONDITIONS THIS MORNING WILL YIELD TO MVFR CEILINGS IN A
STRATOCUMULUS FIELD UNDER THE INFLUENCE OF DAYTIME HEATING. THERE
WILL BE A SHORT DURATION WINDOW OF TSRA AT KMCB...KASD...KNEW...KGPT
BETWEEN 18Z-01Z. BASED ON ABOVE IMPACT DISCUSSION...IF GR IS
INCLUDED AT ANY LOCATIONS IT WOULD BE KASD BETWEEN 19Z-21Z...KMCB
BETWEEN 22Z-23Z AND KGPT BETWEEN 23Z-01Z WHERE A025-A050 IS
POSSIBLE. CONDITIONS IMPROVE TO VFR CAVOK FROM WEST-TO-EAST ONCE THE
SHARP TROUGH AXIS CLEARS THE AREA AROUND AND AFTER 00Z.  24/RR

MARINE...

SMALL CRAFT ADVISORY AND POSSIBLY GALE CONDITIONS WILL IMPACT THE
COASTAL WATERS TODAY AND TONIGHT IN THE WAKE OF A STRONG UPPER
LEVEL TROUGH AXIS AND COLD FRONT. STRONG NORTHWEST WINDS OF 20 TO
30 KNOTS WITH HIGHER GUSTS CAN BE EXPECTED. SEAS WILL RISE TO
AROUND 10 FEET IN THE OUTER GULF WATERS...WITH SEAS OF 7 TO 8 FEET
IN THE NEARSHORE WATERS. IN THE SOUNDS AND LAKES...WAVES OF 4 TO 6
FEET WILL BE POSSIBLE. A MUCH MORE BENIGN PATTERN WILL THEN
DEVELOP LATE WEDNESDAY AND CONTINUE THROUGH THE END OF THE WEEK AS
A SURFACE RIDGE SETTLES OVER THE AREA. WINDS WILL DROP TO LESS
THAN 10 KNOTS AND SEAS WILL FALL BELOW 2 FEET. 32/PG
