Area forecast discussion, Mar 8, 8:04 PM CST, 1 hour 26 minutes before
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NEW ORLEANS LA
804 PM CST TUE MAR 8 2011
.UPDATE...
ADDED NEW HEADLINE FOR TORNADO WATCH 44. ALSO WENT AHEAD AND
BUMPED OVERNIGHT TEMPERATURES UP TO GO CLOSER TO RISING DEWPOINTS
OR ABOUT A DEGREE LOWER THAN CURRENT TEMPS. RICH AIRMASS NOT
ALLOWING FOR ANY COOLING DESPITE RAINFALL IN SOUTHWEST LA. SOME
COOLER NEAR SHORE MARINE INFLUENCES ALONG MS COAST HAS LOWER
TEMPERATURES THUSFAR WHICH SHOULD LEVEL OFF AND POSSIBLY INCREASE
OVERNIGHT. NO OTHER CHANGES AT THIS TIME. 24/RR
&&
.PREV DISCUSSION... /ISSUED 638 PM CST TUE MAR 8 2011/
UPDATE...
NO CHANGES TO CURRENT FORECAST AND THINKING. SEVERE WEATHER STILL
REMAINS MODERATE RISK AS THE SURFACE COLD FRONT IS JUST MOVING
EAST OF THE DALLAS METROPLEX. DEWPOINTS HAVE INCREASED TO 70+F
OVER WESTERN LOUISIANA AND EARLY LOOK AT 00Z SOUNDING SHOWS
HELICITIES INCREASED TO 883 M2/S2 ALONG WITH P.W. INCREASED TO
1.73 INCHES.
RAN RICKS INDEX VALUES ON EFFECTIVE THETA-E 335K LIFTED FROM 940MB
TO PRODUCE A 8% CHANCE OF SEVERE WEATHER...LARGEST THREAT DAMAGING
WINDS AND HEAVY RAINFALL. COMPUTED PCPN 2.44 INCHES WITH POTENTIAL
5.24 INCHES...CONVECTIVE GUSTS 42 KT/48 MPH AND PEA-MARBLE SIZED
HAIL WITH A HAIL-VIL 73. THESE NUMBERS MAY BE DAMPENED BY MARINE
LAYER INFLUENCES...WHICH IF OVERCOME...ALONG WITH 50-60KT LOW
LEVEL WINDS JUST ABOVE BOUNDARY LAYER...TOR THREAT STILL APPEARS
PROMINENT.
TO RE-ITERATE...THIS FIRST ROUND WAS JUST A PRELUDE OF MORE
ACTIVITY TO DEVELOP AND PROGRESS INTO THE AREA OVERNIGHT. UPPER
LEVEL DYNAMICS ALONG WITH INCREASED DIVERGENCE WITH APPROACHING
TROUGH WILL MAKE RAINFALL PROCESSES VERY EFFICIENT AND SUPPORTIVE
OF 3-5 ADDITIONAL INCHES OF RAINFALL. RIVERS AND STREAMS ARE BEING
CLOSELY MONITORED AND FLOOD WARNINGS MAY BE WARRANTED THIS EVENING
ON SEVERAL STREAMS. 24/RR
UPPER AIR...
FLIGHT WENT WELL BUT BURST SLIGHTLY EARLY AROUND 36 MB. VERY
WINDY AND GUSTY CONDITIONS AT LAUNCH AND RELEASED BEHIND
CONVECTION MOVING NORTH. P.W. INCREASED TO 1.73 INCHES UP FROM
1.38 INCHES AT 19Z AND HELICITIES ARE VERY HIGH AT 883 M2/S2. MAX
WINDS 75 KT AROUND 28KFT BUT A RATHER DEEP LOW LEVEL JET 50-55 KT
BETWEEN 1200-4800FT. LAPSE RATES STEEEPENING ABOVE 800 MB WITH A
SUBTLE MARINE LAYER INVERSION BELOW 925 MB. 24/RR
PREV DISCUSSION... /ISSUED 328 PM CST TUE MAR 8 2011/
SHORT TERM...
A HIGHLY SHEARED AND UNSTABLE ENVIRONMENT HAD DEVELOPED ACROSS THE
REGION THIS AFTERNOON...AS A WARM FRONTAL BOUNDARY SURGED
NORTHWARD THROUGH THE CWA. SOME INCREASED LOW LEVEL HELICITY HAS
BEEN NOTED ALONG THE FRONTAL BOUNDARY ACROSS THE NORTHERN THIRD OF
THE CWA. THE 18Z SOUNDING ALSO DEPICTED THIS...WITH SRH VALUES
RUNNING ABOVE 400M2/S2. THE MAIN FACTOR THAT MAY INHIBIT SURFACE
BASED CONVECTION IS A CONTINUING LOW LEVEL INVERSION. HOWEVER...AS
WARMTH AND MOISTURE CONTINUE TO STREAM INTO THE REGION...THIS LOW
LEVEL INVERSION WILL ERODE ALLOWING FOR SURFACE BASED CONVECTION.
MODEL SOUNDINGS INDICATE THAT A STRONGLY SHEARED ENVIRONMENT WILL
CONTINUE THROUGH THE OVERNIGHT HOURS ACROSS THE ENTIRE REGION.
ADDITIONALLY...AS THE UPPER LEVEL TROUGH AXIS APPROACHES...LAPSE
RATES WILL BECOME MORE FAVORABLE WHICH WILL LEAD TO INCREASED
CHANCES FOR HAIL AND DAMAGING WIND EVENTS. THE SEVERE THREAT WILL
CONTINUE THROUGH THE EARLY MORNING HOURS...WITH THE THREAT
DIMINISHING OVER THE NORTHERN AND WESTERN ZONES AROUND DAYBREAK.
BY NOON...THE SEVERE THREAT SHOULD MOSTLY BE CONFINED TO THE MS
COAST AND LOWER PLAQUEMINES PARISH.
HEAVY RAINFALL WILL ALSO BE A LARGE THREAT TONIGHT AND
TOMORROW. THE MAIN CONCERN IS WITH THUNDERSTORMS THAT REPEATEDLY
REDEVELOP OVER THE SAME AREA IN A SHORT PERIOD OF TIME. HOURLY
RAINFALL RATES OF UP TO 3 INCHES PER HOUR WILL BE POSSIBLE IN
THESE AREAS. OVERALL...RAINFALL TOTALS OF UP TO 5 TO 7 INCHES IN
LOCALIZED AREAS WILL BE CONCERN...WITH GENERAL RAINFALL TOTALS OF
3 TO 5 INCHES EXPECTED. RECENT RAINFALL IN THE AREA...HAS LED TO
ALREADY SATURATED GROUND AND HIGHER RIVER LEVELS. THIS ADDITIONAL
RAINFALL WILL QUICKLY RUN OFF INTO TRIBUTARIES...LEADING TO
FLOODING RISKS FOR TONIGHT AND TOMORROW. HAVE KEPT A FLASH FLOOD
WATCH IN EFFECT FOR THE ENTIRE FORECAST AREA THROUGH TOMORROW TO
REFLECT THIS HEAVY RAIN CONCERN.
CONDITIONS WILL RAPIDLY IMPROVE LATE TOMORROW AFTERNOON AND INTO
TOMORROW NIGHT...AS THE MAIN UPPER LEVEL TROUGH AXIS PULLS TO THE
EAST. STRONG NEGATIVE VORTICITY ADVECTION IN THE WAKE OF THE
TROUGH WILL LEAD TO INCREASED UPPER LEVEL SUBSIDENCE AND RAPIDLY
CLEARING SKIES. IN THE LOW LEVELS...STRONG COLD AIR ADVECTION WILL
TAKE HOLD OF THE AREA. DAYTIME HIGHS BY THURSDAY WILL BE A GOOD 10
DEGREES BELOW NORMAL.
LONG TERM...
HEADING INTO THE WEEKEND AND EARLY NEXT WEEK...A MUCH MORE BENIGN
WEATHER PATTERN IS EXPECTED TO TAKE HOLD OF THE GULF SOUTH. IN THE
UPPER LEVELS...A MORE ZONAL FLOW PATTERN WILL SET UP. THIS WILL
ALLOW FOR A GRADUAL MODERATION IN TEMPERATURES FRIDAY AND
SATURDAY...WITH MORE NORMAL TEMPERATURES EXPECTED FOR THE WEEKEND
AND EARLY NEXT WEEK. IN THE LOW LEVELS...A STRONG SURFACE RIDGE
WILL BE CENTERED OVER THE AREA...RESULTING IN CONTINUED CLEAR
SKIES AND LOWER HUMIDITIES.
THERE IS SOME DISAGREEMENT ON THE TIMING OF A FAST MOVING WEAK
UPPER LEVEL LOW THAT SHOULD AFFECT THE AREA MONDAY INTO TUESDAY.
THE EURO IS A BIT SLOWER AND A BIT STRONGER THAN THE GFS WITH THIS
SYSTEM. AT THIS TIME...HAVE LEANED TOWARD THE GFS SOLUTION...WITH
ONLY A SLIGHT CHANCE OF POPS OVER NORTHERN ZONES NOTED IN THE
FORECAST FOR MONDAY.
AVIATION...
UNSETTLED WEATHER WILL CONTINUE TO IMPACT THE TERMINALS THROUGH
THE FORECAST PERIOD. EXPECT STRONG SOUTHERLY WINDS OF UP TO 20
KNOTS...LOW CEILINGS...AND SCATTERED CONVECTION TO BE THE RULE
THROUGH AT LEAST 18Z. EXPECT MVFR AND IFR CEILINGS AT ALL OF THE
TERMINALS...WITH POSSIBLY LOWER CEILINGS DURING PERIODS OF STRONG
CONVECTION. WINDS COULD ALSO GUST TO 35+ KNOTS WITH THIS STRONGER
CONVECTION. VISIBILITIES WILL ALSO BE REDUCED TO POSSIBLY LIFR
CONDITIONS WHEN STRONG CONVECTION IMPACTS ANY TERMINALS.
HOWEVER...PREVAILING VISIBILITIES WILL REMAIN IN THE VFR RANGE. 32
MARINE...
STRONG GRADIENT FLOW ASSOCIATED WITH A STRONG AREA OF LOW PRESSURE
CURRENTLY MOVING FROM THE SOUTHERN PLAINS INTO THE OZARKS WILL
KEEP WINDS ELEVATED THROUGH THE OVERNIGHT HOURS.
ADDITIONALLY...LONG FETCH ACROSS THE GULF OF MEXICO...COMBINED
WITH WIND WAVES WILL LEAD TO SEAS OF UP TO 8 FEET OVER THE COASTAL
WATERS. HAVE KEPT UP THE SMALL CRAFT ADVISORIES FOR ALL OF THE
COASTAL WATERS AND TIDAL LAKES THROUGH THE OVERNIGHT HOURS. THERE
MAY BE A BRIEF LULL IN THE IMMEDIATE VICINITY OF THE FRONT DURING
THE DAY TOMORROW...BUT AT MOST WINDS WILL DROP INTO EXERCISE
CAUTION RANGE. HOWEVER...AS THE COLDER AIRMASS IN THE WAKE OF THE
FRONT OVERSPREADS THE TIDAL LAKES AND COASTAL WATERS...STRONGER
BOUNDARY LAYER WINDS WILL BE MIXED DOWN TO THE SURFACE. THESE
WINDS WILL LEAD TO ANOTHER ROUND OF SMALL CRAFT ADVISORIES FOR
TOMORROW NIGHT AND THURSDAY. HIGH PRESSURE WILL THEN QUICKLY
SETTLE OVER THE AREA THURSDAY NIGHT AND REMAIN IN PLACE THROUGH
THE WEEKEND...WITH LIGHTER WINDS AND CALMER SEAS. 32
