Area forecast discussion, Mar 25, 11:49 PM CDT, 2 hours 12 minutes before

AREA FORECAST DISCUSSION...UPDATED

1149 PM CDT FRI MAR 25 2011

.UPDATE...
UPDATED FOR AVIATION.

&&

.PREV DISCUSSION... /ISSUED 947 PM CDT FRI MAR 25 2011/

UPDATE...

AT 930 PM...THE WARM FRONT WAS EVIDENT FROM CENTRAL ALABAMA...WEST
ACROSS CENTRAL MISSISSIPPI...TO NORTHERN LOUISIANA AND ALONG THE
RED RIVER. TO THE NORTH OF THE FRONT...CLOUDY...COOL...AND FAIRLY
DRY AIR REMAINS IN PLACE ON BRISK NORTHEAST WINDS. SOUTH OF THE
FRONT MUCH MILDER CONDITIONS AND LIGHT SOUTHERLY WINDS PREVAIL.
THINK THIS FRONT WILL REMAIN NEARLY STATIONARY FOR THE REST OF THE
OVERNIGHT. AS THE LLJ BEGINS TO ORGANIZE ACROSS LA AROUND 06Z...SHOULD
START TO SEE THUNDERSTORM INITIATION IN THE ARKLATEX REGION WHICH
WILL EXPAND EASTWARD ALONG THE FRONT LATER TONIGHT AND SATURDAY
MORNING AS THE LLJ VEERS EAST.

REDUCED POPS THROUGH 06Z SINCE THE ACTIVITY WILL REMAIN WEST OF
THE AREA. COULD HAVE REMOVED THEM ALL...BUT PINE BLUFF IS
REPORTING SOME LIGHT RAIN SO WASN/T CONFIDENT ENOUGH TO REMOVE IT
THIS EVENING. TRIMMED THE AREA OF THUNDERSTORM MENTION TO ALONG
AND SOUTH OF I-40 GIVEN THE COOL AND STABLE AIRMASS WELL NORTH OF
THE FRONT AND NIL 00Z NAM MUCAPE IN THOSE AREAS. NEAR AND SOUTH OF
THE FRONT WILL STAND THE BEST CHANCE OF THUNDER. ALSO UPDATED FOR
CURRENT TEMP/WIND/TD TRENDS FOR TONIGHT.

THE FRONT WILL CONTINUE TO REMAIN NEARLY STATIONARY THROUGH
SATURDAY AS LOW PRESSURE TRACKS ALONG IT. THE COOL NORTHEAST FLOW
WITH WIDESPREAD CLOUDS AND RAIN NORTH OF THE FRONT WILL PROBABLY
KEEP TEMPS QUITE COOL...SO LOWERED HIGHS TOWARD THE 00Z NAM 2
METER GUIDANCE. ALONG AND SOUTH OF THE FRONT IT WILL BE QUITE WARM
AND UNSTABLE WITH POTENTIAL OF 2000+ J/KG OF SBCAPE BY LATE
AFTERNOON. STEEP MID LEVEL LAPSE RATES AND STRONG SHEAR WILL
PROMOTE SUPERCELL DEVELOPMENT AS THE LOW TRACKS ACROSS NORTHERN MS
BETWEEN 21Z-06Z. ADDED MENTION OF LARGE HAIL TO MUCH OF NORTHERN
MS TOMORROW AFTERNOON/EVENING COINCIDENT WITH 30 PCT SPC DY2 OTLK
AREA.

GRIDS PUBLISHED AND ZONES UPDATED.

BORGHOFF

PREV DISCUSSION... /ISSUED 408 PM CDT FRI MAR 25 2011/

DISCUSSION...20Z SURFACE ANALYSIS PLACES A DEVELOPING SURFACE LOW
ACROSS THE SOUTHERN PLAINS WITH A WARM FRONT EXTENDING FROM THE
SURFACE LOW BACK THROUGH LOUISIANA AND SOUTHERN MISSISSIPPI.
ACROSS THE MID SOUTH THIS AFTERNOON...CLOUDY SKIES HAVE KEPT
TEMPERATURES IN THE 50S ACROSS AREAS ALONG AND NORTH OF I-40 AND
LOWER 60S ACROSS NORTH MISSISSIPPI. SEVERE THUNDERSTORM POTENTIAL
TONIGHT AND SATURDAY ARE THE PREDOMINANT CONCERNS IN THIS
AFTERNOON/S FORECAST PACKAGE.

SHORT TERM...(TONIGHT THROUGH MONDAY)...A WARM FRONT CURRENTLY
LOCATED ACROSS SOUTHERN MISSISSIPPI AND LOUISIANA WILL GRADUALLY
BEGIN TO MOVE NORTH TONIGHT TOWARDS THE MID SOUTH AS A DEVELOPING
SURFACE LOW ACROSS TEXAS GRADUALLY BEGINS TO MOVE TOWARDS WESTERN
SECTIONS OF THE LOWER MISSISSIPPI VALLEY. MEANWHILE ALOFT...A
SUBTLE SHORTWAVE EMBEDDED WITHIN NEARLY ZONAL MID LEVEL FLOW WILL
MOVE ACROSS THE REGION. 310-320K SURFACES SHOW INCREASING
ISENTROPIC ASCENT TONIGHT...ESPECIALLY DURING THE OVERNIGHT HOURS.
AT THIS TIME THINK BEST COVERAGE WILL BE DURING THIS TIMEFRAME AND
WENT WITH CHANCE POPS FOR THIS EVENING AND LIKELY/CATEGORICAL POPS
FOR THE OVERNIGHT HOURS. ANY THUNDERSTORMS ARE EXPECTED TO REMAIN
ELEVATED WITH THE OVERALL THREAT FOR ANY THUNDERSTORMS TO BECOME
SEVERE LOW.

WRF/GFS/ECMWF MODELS ALL INDICATE THE WARM FRONT WILL RESIDE
SOMEWHERE SOUTH OF I-40 ON SATURDAY...MOST LIKELY ACROSS NORTH
MISSISSIPPI TOWARDS CENTRAL MISSISSIPPI WITH A TRAILING LOW MOVING
EAST ACROSS THE LOWER MISSISSIPPI VALLEY SATURDAY NIGHT INTO
SUNDAY MORNING. HOWEVER...SOME UNCERTAINTY REMAINS WITH RESPECT
TO THE EXACT POSITION OF THE WARM FRONT WHICH WILL AFFECT HIGH
TEMPERATURES SATURDAY AND MOST IMPORTANTLY THE THERMODYNAMICS THAT
WILL ENHANCE ANY THUNDERSTORM POTENTIAL AND THE OVERALL THREAT FOR
SEVERE THUNDERSTORMS.

SURFACE BASED CAPE/MOST UNSTABLE CAPE VALUES BETWEEN 1600-1900
J/KG...LI/S BETWEEN -4 TO -6...VERY STEEP 700-500 MB LAYER MID
LEVEL LAPSE RATES BETWEEN 7 TO 8 C/KM...AND SURFACE DEWPOINTS IN
THE LOWER 60S ALONG THE WARM FRONT WILL BE CONDUCIVE FOR DECENT
THERMODYNAMICS. SOME WEAK BUT ACCEPTABLE UPPER LEVEL DIVERGENCE
ALOFT AND ANOTHER SHORTWAVE TROUGH EMBEDDED WITHIN NEARLY ZONAL
FLOW ALOFT WILL MOVE ACROSS THE REGION SATURDAY. THIS IS
ANTICIPATED TO ASSIST IN THE DEVELOPMENT OF SHOWERS AND
THUNDERSTORMS...ESPECIALLY DURING THE AFTERNOON AND EARLY EVENING
HOURS. 0-1KM STORM RELATIVE HELICITY VALUES BETWEEN 300-500
M2/S2 AND 0-6KM BULK SHEAR VALUES BETWEEN 55-80 KTS WILL SUPPORT
THE POTENTIAL FOR SOME MINI-SUPERCELLULAR TYPE TORNADOES ALONG
THIS BOUNDARY. BASED ON THE ABOVE DATA THINK THE BEST CHANCES FOR
SEVERE THUNDERSTORMS WILL RESIDE ACROSS AREAS MAINLY ALONG AND
SOUTH OF THE TENNESSEE/MISSISSIPPI STATE LINE. WILL CONTINUE TO
MENTION LARGE HAIL...DAMAGING WINDS...AND THE POTENTIAL FOR
TORNADOES IN THE HAZARDOUS WEATHER OUTLOOK. PRECIPITABLE WATER
VALUES BETWEEN 1.2 TO 1.4 INCHES WILL ALSO SUPPORT THE POTENTIAL
FOR LOCALIZED FLASH FLOODING FROM THE THUNDERSTORMS. EVENING SHIFT
WILL CONTINUE TO MONITOR SHORT TERM MESOSCALE TRENDS AND ADJUST
FORECAST AS NECESSARY AS THIS POTENTIAL SEVERE WEATHER EVENT
BEGINS TO EVOLVE. STAY TUNED...

SHOWERS AND THUNDERSTORMS WILL GRADUALLY COME TO AN END SATURDAY
NIGHT AND SUNDAY AS THE SURFACE LOW MOVES EAST OF THE MID SOUTH.
DESPITE THE PASSAGE OF THE SURFACE LOW...UPPER LEVEL FLOW WILL
REMAIN NEARLY ZONAL AND CONFIDENCE ON PRECIPITATION CHANCES FOR
SUNDAY NIGHT AND MONDAY REMAIN CHALLENGING DUE TO LOW CONFIDENCE
IN TIMING OF SUBTLE SHORTWAVES EMBEDDED WITHIN THE UPPER LEVEL
FLOW.

LONG TERM...(TUESDAY THROUGH FRIDAY)...12Z LONG RANGE MODELS
CONTINUE TO INDICATE A BROAD UPPER LEVEL TROUGH AXIS MOVING
THROUGH THE REGION BY THE MIDDLE OF NEXT WEEK. SOME UNCERTAINTY
REMAINS WITH THE OVERALL SPEED OF THIS NEXT SYSTEM AS THE 12Z
ECMWF IS MUCH QUICKER THAN THE 00Z ECMWF AND THE LAST 2 RUNS OF
THE GFS. FOR NOW WENT WITH CONSENSUS AND KEPT POPS ON THE LOW SIDE
FOR THE REMAINDER OF THE FORECAST.

CJC

&&

.AVIATION...
06Z TAFS

FEW CHANGES FROM 00Z PACKAGE...OTHER THAN A SLIGHT DELAY IN MVFR
CIGS IN THE SHORT TERM. ELEVATED TSRA STILL EXPECTED TO DEVELOP
THROUGH THE OVERNIGHT. RAIN FALLING INTO THE COOL STABLE AIR WILL
HELP REINFORCE THE LOW LEVEL INVERSION AND STRATUS. BY 12Z...
EXPECT MVFR TO PREVAIL WITH POCKETS OF IFR CIGS.

FOR SATURDAY... PERIODS OF RAIN SHOWERS WILL CONTINUE. BEST EARLY
AFTERNOON TS POTENTIAL AT KTUP...WHICH SHOULD BE JUST NORTH OF THE
WARM FRONT. MOST INTENSE/ORGANIZED TSRA SHOULD OCCUR OVER NORTHEAST
MS AFTER 22Z... PERSISTING UNTIL 03Z OR SO SOUTH OF THE TUP VICINITY.
