AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
848 AM CDT FRI JUN 4 2010
.UPDATE...
...SOUNDING DISCUSSION...
NO PROBLEMS WITH THE FLIGHT THIS MORNING. A VERY UNSTABLE SOUNDING
THIS MORNING WITH AN ABUNDANT AMOUNT OF MOISTURE ASIDE A WEAK CAP
OF DRY AIR ABOVE 920 MILLIBARS WITH A PW OF 1.68 INCHES AND AN LI
OF -8.9. SINCE THE CAP IS RELATIVELY WEAK AND CLOSE TO THE SURFACE...IT
WILL LIKELY ERODE FAIRLY QUICKLY ALLOWING FOR ANOTHER VERY ACTIVE
DAY FOR STRONG TO SEVERE THUNDERSTORMS. SHEAR HAS INCREASED SLIGHTLY
OVER THE PAST 24 HOURS AS WELL...THEREFORE CANNOT RULE OUT ISOLATED
TORNADOES WITH THE STRONGER STORMS.
&&
.PREV DISCUSSION... /ISSUED 703 AM CDT FRI JUN 4 2010/
AVIATION...
TSRA/SHRA MOVING NNE TOWARD BTR AREA AHEAD OF LINE OF STRONG STORMS
FROM NEAR KIER-KLFT-KEHC PLATFORM. EXPECT THAT STORMS PRECEDING THE
LINE WILL BECOME MORE NUMEROUS AS IMPRESSIVE AND STRONGER DEEP
LAYER SHEAR JUST OFFSHORE MOVES INLAND NEAR AND NW OF KHUM. HAVE
ALREADY MENTIONED GUSTS IN TSRA BUT WILL BE UPPING WIND GUSTS
THERE AND AT HUM FOR THE MORNING HOURS. THEN BULK OF STORMS HIT
MSY/NEW BETWEEN 16-20Z...AND 17-22Z HSA/GPT.
FOR THE LATER PERIODS THE UPPER LOW WILL SLOWLY APPROACH AND MORE
SHRA/TSRA SHOULD DEVELOP NEAR BTR AFTER 05/10Z AND NEAR GPT A LITTLE
EARLIER. KP
PREV DISCUSSION... /ISSUED 357 AM CDT FRI JUN 4 2010/
SYNOPSIS...
WELL DEFINED SURFACE AND UPPER LOW SYSTEMS ARE CENTERED NEAR
HOUSTON EARLY THIS MORNING. WEAK WARM FRONT APPEARS TO BE RESIDING
NEAR INTERSTATE 10 WITH SLIGHTLY HIGHER DEW POINTS AND A LITTLE
MORE WIND TO THE SOUTH OF THE BOUNDARY. MOST CONVECTION AT THIS
TIME APPEARS TO BE LIMITED TO SOUTHWEST LOUISIANA...BUT A
THUNDERSTORM OR TWO HAVE DEVELOPED IN THE LAST 30 MINUTES IN THE
ATCHAFALAYA RIVER BASIN. TEMPERATURES AND DEW POINTS GENERRALLY IN
THE LOW TO MID 70S.
SHORT TERM...
SHORT RANGE MODELS UNUSUALLY CONSISTENT IN HANDLING LOW PRESSURE
SYSTEM THROUGH AT LEAST SATURDAY WITH THE LOW CENTERS MOVING INTO
SOUTHERN LOUISIANA. EXPECT NUMEROUS SHOWERS AND THUNDERSTORMS TO
DEVELOP...MAINLY DURING THE DAYLIGHT HOURS...OVER THE NEXT TWO
DAYS.
ENHANCED MID LEVEL WINDS ASSOCIATED WITH THE UPPER LOW MAY
BRING A FEW STORMS NEAR SEVERE LIMITS THIS AFTERNOON...WITH THE
MAIN THREAT DAMAGING WINDS...ALTHOUGH AN ISOLATED TORNADO CANNOT
BE TOTALLY RULED OUT. WHILE WIDESPREAD HEAVY RAIN IS NOT
ANTICIPATED...AREAS THAT SEE MULTIPLE THUNDERSTORMS COULD RECEIVE
2-4 INCHES OF RAIN WITH VERY ISOLATED HIGHER AMOUNTS. SIMILAR
CONDITIONS ARE EXPECTED SATURDAY...ALTHOUGH AREAL COVERAGE WILL BE
SOMEWHAT LESS AS UPPER LOW WEAKENS. AS LOW SHEARS OUT ON
SUNDAY...POPS FALL BACK INTO THE SCATTERED RANGE.
TEMPERATURES SHOULD REMAIN WITHIN A COUPLE OF DEGREES OF NORMAL
TODAY AND SATURDAY...ALTHOUGH A FEW AREAS THAT RECEIVE
THUNDERSTORMS EARLY ENOUGH IN THE DAY WILL COME UP SOMEWHAT SHORT
ON MAX TEMPS. 35
LONG TERM...
UPPER RIDGE BUILDS INTO THE AREA FROM THE WEST ON SUNDAY AND
MONDAY...AND TAKES UP RESIDENCE OVER THE GULF COAST FOR THE WORK
WEEK NEXT WEEK. WARMER TEMPERATURES AT 700 MB SHOULD HELP LIMIT
THE AREAL COVERAGE OF ANY CONVECTION THAT TRIES TO DEVELOP.
MENTION OF PRECIPITATION WILL BE LIMITED TO 20 POPS DURING THE
AFTERNOONS.
THE MORE NOTICEABLE EFFECT OF THE RIDGE WILL BE HOTTER
TEMPERATURES. GUIDANCE HAS BEEN CONSISTENT IN ADVERTISING HIGH
TEMPERATURES IN THE MID 90S FOR MUCH OF NEXT WEEK. WITH MODERATE
HUMIDITY...HEAT INDICES OF 105 OR HIGHER WILL BE POSSIBLE IN MANY
AREAS DURING THE HEAT OF THE AFTERNOON NEXT WEEK. WILL CONTINUE
MENTION IN HWO...AND HEAT ADVISORIES WILL BE A POSSIBILITY AS WE
GET TO SUNDAY OR MONDAY. 35
AVIATION...
PATCHY LOW CLOUDS AND FOG EARLY THIS MORNING NOW PRIMARILY CONFINED
TO AREAS NORTHWEST OF MCB. SCATTERED SHOWERS WILL SPREAD INTO THE
BTR/HUM TERMINALS EARLY THIS MORNING AS LIFT INCREASES AHEAD OF THE
NEXT S/W AND MCS RACING TOWARD THE REGION FROM THE SW. MODERATE
SOUTHERLY FLOW 10-15 KNOTS AND GUSTY WITH MORE WIDESPREAD
THUNDERSTORMS AROUND 15Z-18Z AT THESE SITES THEN EXPANDING EASTWARD
REACHING MSY/NEW 16-20Z...AND HSA/GPT AFTER 18Z. 15Z AND BEYOND
EXPECT CIGS 2500 FT AND ABOVE. UPPER LOW WILL SLOWLY APPROACH AND
MORE SHRA/TSRA SHOULD DEVELOP NEAR BTR AFTER 05/10Z AND NEAR GPT A
LITTLE EARLIER. KP
MARINE...
SURFACE LOW OVER SABINE RIVER WILL CONTINUE TO SLOWLY MOVE TO
THE ENE TODAY WHILE AN UPPER LOW WILL ALSO TRACK ACROSS THE NRN
GULF AND TOWARDS CENTRAL MS BY TOMORROW BEFORE OPENING UP AND
LIFTING NE OUT TO THE ATLANTIC SEABOARD. THIS WILL MAKE FOR AN
ACTIVE AND WINDY DAY. LARGE AREA OF SHOWERS AND THUNDERSTORMS JUST
SOUTHEAST OF BROWNSVILLE IS ASSOCIATED WITH A DISTURBANCE THAT
WILL MOVE TO THE NORTHEAST TODAY AND SHOULD BEGIN THE COASTAL
WATERS AROUND 15Z. NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED
TO DEVELOP WITH THIS FEATURE. IN ADDITION TO THAT WINDS ARE
EXPECTED TO RAMP UP THROUGH THE MID/LATE MORNING HOURS AND SHOULD
APPROACH 15-20 KNOTS SUSTAINED WITH FREQUENT HIGHER GUSTS POSSIBLY
UP TO 30 KNOTS. WITH THAT A SMALL CRAFT ADVISORY WILL BE IN EFFECT
FOR ALL OF TODAY. THE UPPER LOW IS EXPECTED TO OPEN UP PUSH OFF TO
THE NORTHEAST BY LATE TOMORROW SO WE COULD SEE ANOTHER ACTIVE DAY
FOR MUCH OF THE REGION TOMORROW(NOT LIKELY AS ACTIVE AS TODAY
THOUGH). WINDS WILL REMAIN ON THE ELEVATED SIDE THROUGH FIRST HALF
OF THE WEEKEND WITH THINGS CALMING DOWN LATE SUNDAY AND ESPECIALLY
AS WE MOVE INTO NEXT WEEK. /CAB/
