A WIND ADVISORY REMAINS IN EFFECT FROM 9 AM TO 5 PM CDT SATURDAY.

RAPIDLY INCREASING LOW LEVEL PRESSURE GRADIENTS ACROSS THE LOWER
MISSISSIPPI VALLEY WILL CAUSE SOUTH TO SOUTHEAST SURFACE WINDS TO
STRENGTHEN QUICKLY SATURDAY MORNING ACROSS THE REGION. BY
MIDDAY...EXPECT SUSTAINED WINDS UP TO AT LEAST 20 MPH IN MOST
AREAS OF EXTREME SOUTHEAST ARKANSAS...NORTHEAST LOUISIANA...AND
CENTRAL MISSISSIPPI...WITH GUSTS OVER 30 MPH LIKELY AS WELL. THE
STRONGEST WINDS SHOULD BE CONFINED TO THE UPPER DELTA AREAS OF
NORTHWEST MISSISSIPPI...EXTREME NORTHEAST LOUISIANA AND CHICOT
COUNTY IN ARKANSAS...WHERE SUSTAINED WINDS OF 25 TO 30 MPH WILL
BE POSSIBLE WITH GUSTS TO 40 MPH NOT OUT OF THE QUESTION.

A WIND ADVISORY MEANS THAT WINDS OF 35 MPH ARE EXPECTED. WINDS
THIS STRONG CAN MAKE DRIVING DIFFICULT...ESPECIALLY FOR HIGH
PROFILE VEHICLES. USE EXTRA CAUTION.

WIND GUSTS OF 30 TO 40 MILES PER HOUR OCCASIONALLY BRING DOWN
LARGE LIMBS AND ROTTED TREES CAUSING SERIOUS INJURY AND PROPERTY
DAMAGE. EXERCISE CAUTION WHEN OUTDOORS DURING THESE STRONG WINDS.

AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE JACKSON MS
1045 AM CDT FRI APR 28 2006

.DISCUSSION...
MID TO HIGH LEVEL CLOUD SHIELD IS STARTING TO PUSH NORTHEAST INTO
THE ARKLAMISS...WITH AREA RADARS SHOWING SCATTERED ECHOES ORIENTED
NORTHWEST TO SOUTHEAST. THESE ECHOES (AND ASSOCIATED CLOUDS) ARE
BEING GENERATED ABOVE 10 KFT (600 TO 400 MB) THROUGH ISENTROPIC
ASCENT AS SOUTHWESTERLY FLOW WORKS INTO THE LOWER MISSISSIPPI VALLEY
AHEAD A GATHERING STORM SYSTEM IN THE PLAINS. GFS INDICATES A LITTLE
CONVECTIVE INSTABILITY FOR PARCELS BASED AT ROUGHLY 10 KFT AS A
MINOR LEAD WAVE IN 500 MB FLOW PASSES OVERHEAD THIS AFTERNOON.
NLDN DATA HAS BEEN SHOWING LOTS OF LIGHTNING WITH MORE CONCENTRATED
CONVECTION IN NORTHWEST ARKANSAS...BUT THERE HAVE EVEN BEEN A FEW
STRIKES COMING INTO NORTHWEST LA IN THE PAST HOUR OR TWO AS WELL.

BUT EVEN WITH THE PRECIP GOING ON ALOFT...THE BOUNDARY LAYER ACROSS
THE WHOLE OF THE REGION REMAINS QUITE DRY AND MIXED...BUT PERHAPS A
LITTLE LESS SO IN THE SOUTHWEST CORNER OF THE CWA. THIS MAKES THE
PROSPECT OF SEEING MEASURABLE RAIN AT THE SURFACE UNDERNEATH ECHOES
ALOFT PRETTY SLIM GENERALLY. HOWEVER...THE HEAVY PRECIP ALOFT
UNDERNEATH ANY THUNDEROUS CONVECTION STANDS A MUCH BETTER CHANCE OF
MAKING IT TO THE GROUND AFTER BATTLING EVAPORATION IN THE BOUNDARY
LAYER.

TAKING IN ACCOUNT ALL OF THE ABOVE...I TWEAKED AROUND POPS SOME FOR
THE REMAINDER OF THE 1ST PERIOD...ADDING THUNDER IN WESTERN ZONES
AND ADDING SOME SPRINKLE WORDING FURTHER EAST INTO THE I-55
CORRIDOR. OTHERWISE...TEMPERATURES AND CLOUDCOVER LOOKED ALRIGHT
THROUGH 00Z. NEW ZONES AND GRIDS OUT. /BB/

&&

.PREVIOUS DISCUSSION...
FOR TODAY...THE WEEKEND IS STILL SHAPING UP TO BE ACTIVE WITH A
POTENTIAL FOR HEAVY RAINFALL AND A FEW SEVERE THUNDERSTORMS. AS WAS
ADVERTISED BY THE GFS SEVERAL DAYS AGO...WATER VAPOR IMAGERY SHOWS
THAT STRONG NORTHERN AND SOUTHERN STREAM TROUGHS ARE COMING INTO
PHASE OVER THE PLAINS. THE RESULTING FULL-LATITUDE TROUGH WILL
EVENTUALLY CLOSE OFF THIS WEEKEND AND SEND A STRONGLY FORCED BAND OF
HEAVY CONVECTION ACROSS THE FORECAST AREA...ESPECIALLY DURING THE
PERIOD FROM SAT AFTN THROUGH SAT NIGHT. SHEAR WILL BE VERY
IMPRESSIVE...BUT INSTABILITY CONTINUES TO BE A QUESTION.

A WEAK HEIGHT FALL CENTER AND INITIAL SHOT OF LOW LEVEL THETAE
ADVECTION WILL MOVE INTO AREAS ALONG AND W OF THE MS RIVER THIS AFTN
AND THERE COULD BE ENOUGH CONVECTIVE INSTABILITY FOR ISO/SCT
SHOWER DEVELOPMENT AND HAVE FOLLOWED THE CHANCE MAV GUIDANCE POPS
FOR THIS. THESE SHOWERS SHOULD THEY DEVELOP WOULD AFFECT NORTH
CENTRAL MS DURING THE EVENING.

THE MAIN SHOW WILL START SATURDAY AS WHAT SHOULD BE A LARGE LINEAR
MESOSCALE CONVECTIVE SYSTEM ASSOC WITH THE PRIMARY MID LEVEL HEIGHT
FALL AXIS SURGES EASTWARD FROM TX INTO SRN AR/LA. THERE ARE
SIGNIFICANT DIFFERENCES IN TIMING AMONGST THE MODELS WITH NAM-ETA
AND UKMET MUCH SLOWER THAN THE GFS. EXPECT THAT THE COLD POOL EFFECT
WILL HELP THE GFS VERIFY EVEN IF IT IS A LITTLE FAST SYNOPTICALLY
SPEAKING. THERE ISNT MUCH SPREAD AMONG THE GFS ENSEMBLE MEMBERS AND
THE GFS ENSEMBLE MEAN IS RIGHT IN LINE WITH THE OPERATIONAL GFS.
ALSO...THE GFS INDICATES A WEAK HEIGHT FALL CENTER COULD INITIATE
ELEVATED SHOWER/ISOLATED THUNDER ACTIVITY WELL AHEAD OF THE LCS.

CONCERNING SEVERE WEATHER POTENTIAL: SHEAR FORECASTS BY ALL MODEL
GUIDANCE CONTINUE TO BE VERY IMPRESSIVE (AFTER TAKING INTO ACCOUNT
GRID-SCALE FEEDBACK CONTAMINATION) (50-70KT 0-6KM, 30-40KT 0-1KM)
AND THE 0-1KM VORTICITY GENERATION PARAMETER GOES THROUGH THE ROOF
ACROSS EAST CENTRAL LA/SW MS LATE SAT AFTN/EVNG. MID LEVEL LAPSE
RATES (500MB TEMPS FROM -8 TO -10 DEG C) AND CONVECTIVE INSTABILITY
CONTINUE TO BE THE BIG NEGATIVES FOR GETTING A SEVERE WEATHER
OUTBREAK AS MOST UNSTABLE CAPES REMAIN GENERALLY BELOW 500 J/KG AND
TT VALUES BELOW 50 IN ASSOC WITH THE LCS AS IT MOVES ACROSS.
SFC-BASED INSTABILITY WILL BE SEVERELY LIMITED GIVEN THAT LOW LEVEL
TRAJECTORIES AHEAD OF THE LCS WILL BE EMANATING FROM A STRONG SFC
RIDGE OVER THE EASTERN STATES. WITH THAT SAID...THERE WILL BE A
SMALL WINDOW OF OPPORTUNITY FOR SEVERE WEATHER LATE SAT AFTN AND
EVNG...ESPECIALLY SOUTH OF INTERSTATE 20 AND ON THE WRN FLANK OF THE
LCS WHERE CONVECTION MAY BE MORE CELLULAR. STEEPER MID LEVEL LAPSE
RATES AND RICH BOUNDARY LAYER MOISTURE WILL ALLOW LOW LEVEL
INSTABILITY (MIXED LAYER CAPES > 500 J/KG) TO INCREASE AND CONTINUED
STRONG SHEAR AND STRONG POTENTIAL LOW LEVEL VORTICITY GENERATION
COMBINED WITH WHAT SHOULD BE A LOW-LCL ENVIRONMENT SUGGEST THERE
WILL BE A TORNADO RISK...ESPECIALLY IF DISCRETE CELLS DEVELOP. WILL
EMPHASIZE THIS POTENTIAL IN THE HWO OVER SRN PORTIONS OF THE
FORECAST AREA...BUT NRN PORTIONS OF THE FORECAST AREA WILL HAVE A
LESSER RISK FOR SEVERE WEATHER...AT LEAST FOR SAT AFTN/EVNG...GIVEN
THAT THE LCS SHOULD ACT TO INTERCEPT MUCH OF THE LOW LEVEL MOISTURE
TRANSPORT AND INSTABILITY. HOWEVER...A MORE UNSTABLE ENVIRONMENT IS
EXPECTED TO DEVELOP LATE SAT NIGHT AND IF TSTMS CAN REDEVELOP WITH
THE COLD FRONT...A GREATER RISK FOR SEVERE WEATHER COULD DEVELOP NRN
AREAS THEN.

CONCERNING HEAVY RAIN POTENTIAL...INTENSE RAINFALL RATES WILL
LIKELY ACCOMPANY THE SAT AFTN/EVNG LCS GIVEN STRONG FORCING COMBINED
WITH PRECIP WATER VALUES NEAR 2 INCHES...850MB THETAE VALUES >335...
AND DEEP WARM CLOUD LAYER/MOIST ADIABATIC PROFILES (IE.
TROPICAL-LIKE AIRMASS). EXPECT THAT WITH TIME...THE HEAVIEST RAIN
WILL GRADUALLY BECOME MORE SUPPRESSED AS THE LCS MOVES INTO A MORE
STABLE/DRIER ENVIRONMENT AND THE MOISTURE IS INTERCEPTED AS
DESCRIBED ABOVE. OVERALL...EXPECT 2 TO 3 INCH RAINFALL AMOUNTS COULD
BE COMMON ESPECIALLY ALONG AND SOUTH OF INTERSTATE 20 AND WOULD NOT
RULE OUT THE ISSUANCE OF A FLASH FLOOD WARNING OR TWO. ONCE
AGAIN...WILL CONVEY THIS RISK IN THE HWO. /EC/

LONG TERM (SUNDAY THROUGH NEXT FRIDAY)...THE MAIN FOCUS OF THE LONG
TERM FORECAST AFTER SATURDAYS STORM SYSTEM...WILL BE THE NEXT STORM
SYSTEM THAT WILL DEVELOP OVER THE PLAINS ON THURSDAY.

AS THE WEEKEND UPPER TROUGH/STORM SYSTEM AXIS PIVOTS THROUGH THE
REGION ON SUNDAY THE RAINS WILL GRADUALLY END FROM THE WEST DURING
THE DAY. THE ASSOCIATED UPPER LOW WILL REMAINED PARKED AROUND THE
MIDDLE MISSISSIPPI VALLEY UNTIL EARLY NEXT WEEK. THIS SYSTEM WILL
BRING A FRONT THROUGH THE REGION ON TUESDAY. THERE WILL BE ENOUGH
LIMITED INSTABILITY FOR A CHANCE OF SHOWERS AND THUNDERSTORMS WITH
THE PASSAGE MONDAY NIGHT INTO TUESDAY. A SERIES OF WEAK DISTURBANCES
WILL COME ACROSS THE REGION IN NORTHWEST FLOW...WHICH WILL KEEP OUR
CONVECTIVE CHANCES OF RAIN GOING THROUGH WEDNESDAY. MEANWHILE A
NORTHERN STREAM UPPER TROUGH WILL MOVE THROUGH THE NORTHERN
PLAINS ON WEDNESDAY. THIS SYSTEM WILL DEEPEN AS IT DEVELOPS A CLOSED
UPPER LOW TOWARD THE CENTRAL PLAINS ON THURSDAY. THIS INTENSE CLOSED
UPPER LOW WILL PUSH INTO THE MISSISSIPPI VALLEY ON FRIDAY. IT WILL
PUSH A COLD FRONT THROUGH THE REGION ON THURSDAY NIGHT INTO FRIDAY.
THERE COULD BE SOME STRONG STORMS WITH THIS SYSTEM. THIS WILL BEAR
WATCHING.

OTHERWISE WENT CLOSE TO MEX POPS AND TEMPS AS WELL AS SOME ENSEMBLE
TEMPS. /17/
