THE NATIONAL WEATHER SERVICE IN LAKE CHARLES HAS ISSUED A

* TORNADO WARNING FOR...
SOUTHERN EVANGELINE PARISH IN CENTRAL LOUISIANA...
THIS INCLUDES THE CITIES OF...VILLE PLATTE...MAMOU...
NORTHWESTERN ST. LANDRY PARISH IN CENTRAL LOUISIANA...

* UNTIL 330 PM CST

* AT 232 PM CST...NATIONAL WEATHER SERVICE METEOROLOGISTS DETECTED
A SEVERE THUNDERSTORM CAPABLE OF PRODUCING A TORNADO NEAR
SOUTHWEST OF MAMOU...MOVING NORTHEAST AT 30 MPH.

* THE TORNADO WILL BE NEAR...
MAMOU BY 240 PM CST...
VILLE PLATTE BY 255 PM CST...

PRECAUTIONARY/PREPAREDNESS ACTIONS...

NATIONAL WEATHER SERVICE RADAR INDICATES A TORNADO MAY FORM AT ANY

AREAS AFFECTED...SERN TX INTO PARTS OF SRN/CNTRL LA AND SWRN MS

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 202022Z - 202145Z

THE THREAT FOR ISOLATED SEVERE STORMS INCLUDING SUPERCELLS APPEARS
TO BE INCREASING ACROSS THE DISCUSSION AREA. CONVECTIVE TRENDS ARE
BEING MONITORED FOR A POSSIBLE WW.

RECENT TRENDS IN REGIONAL RADAR IMAGERY INDICATE A GRADUAL
INTENSIFICATION OF TSTMS N OF THE I-10 CORRIDOR. INSPECTION OF
LOCAL VWP DATA SUGGESTS THAT THIS ACTIVITY IS BEING DRIVEN BY
LOW-LEVEL WAA WITH STORMS LIKELY STILL SLIGHTLY ELEVATED BASED ON
OBSERVED MOTIONS. AMBIENT AIR MASS HAS WARMED INTO THE LOWER 70S AS
OF 20Z...AND WHEN COUPLED WITH DEWPOINTS IN THE MID
60S...ENVIRONMENT HAS BECOME MODERATELY UNSTABLE WITH MLCAPE OF
1500-2000 J/KG.

WHILE THE STRONGER LARGE-SCALE FORCING FOR ASCENT ASSOCIATED WITH
SRN HIGH PLAINS VORTICITY MAXIMUM IS EXPECTED TO REMAIN WELL TO THE
W OF REGION FOR THE NEXT SEVERAL HOURS...IT APPEARS THE PERSISTENT
WAA WILL LIKELY CONTINUE TO BE THE PRIMARY MECHANISM SUSTAINING THIS
STORM ACTIVITY.

CONTINUED HEATING/MOISTENING OF BOUNDARY LAYER MAY EVENTUALLY
SUPPORT A TRANSITION TO SURFACE-BASED STORMS WITHIN A WIND PROFILE
CHARACTERIZED BY DEEP-LAYER SHEAR OF AROUND 40 KT AND 0-1 KM SRH OF
100-200 M2/S2. AS SUCH...THE PROBABILITY OF SUPERCELL FORMATION IS
INCREASING WITH ATTENDANT THREATS FOR HAIL...LOCALLY STRONG WIND
GUSTS AND PERHAPS A TORNADO OR TWO.

MESOSCALE DISCUSSION 0023
NWS STORM PREDICTION CENTER NORMAN OK
0149 PM CST WED JAN 20 2010

AREAS AFFECTED...WESTERN PARTS OF NORTH TX

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 201949Z - 202115Z

THE THREAT FOR SEVERE STORMS INCLUDING SUPERCELLS IS EXPECTED TO
INCREASE ACROSS DISCUSSION AREA THROUGH THE REMAINDER OF THE
AFTERNOON. CONVECTIVE TRENDS ARE BEING MONITORED FOR A WW
ISSUANCE.

SURFACE FRONT WHICH STALLED FROM S-CNTRL OK INTO W-CNTRL TX EARLIER
TODAY HAS SINCE RETREATED NWD TO VICINITY OF THE RED RIVER IN
RESPONSE TO THE EWD DEVELOPMENT OF A SURFACE LOW INTO FAR SERN CO.
AT THE SAME TIME...INCREASING WLY WIND FIELD ASSOCIATED WITH STRONG
VORTICITY MAXIMUM NOW MOVING INTO THE SRN HIGH PLAINS IS RESULTING
IN THE DEVELOPMENT OF A DRYLINE FROM THE LOW ROLLING PLAINS INTO WRN
EDWARDS PLATEAU REGION AS OF 19Z.

DEEPER PBL MIXING INVOF AND IMMEDIATELY E OF DRYLINE HAS ALLOWED FOR
THE EROSION OF LOW CLOUDS WITH TEMPERATURES WARMING THROUGH THE 60S
INTO LOWER 70S. BASED ON 18Z FWD SOUNDING...TEMPERATURES OF
MID/UPPER 70S WOULD ELIMINATE MUCH OF THE REMAINING CONVECTIVE
INHIBITION WITH MLCAPE APPROACHING 1500-2000 J/KG. LATEST RUC/SREF
GUIDANCE SUGGESTS THAT THE CONTINUED BOUNDARY LAYER WARMING COUPLED
WITH INCREASING DYNAMIC COOLING/FORCING FOR ASCENT ASSOCIATED WITH
SHORT WAVE TROUGH WILL RESULT IN THE LIKELIHOOD OF STORM INITIATION
AFTER 21-23Z.

BOTH FORECAST HODOGRAPHS AND CURRENTLY OBSERVED VWP/PROFILER DATA
INDICATE SUFFICIENT /40-50 KT/ DEEP-LAYER SHEAR FOR ORGANIZED STORMS
INCLUDING SUPERCELLS CAPABLE OF LARGE HAIL AND DAMAGING WIND GUSTS.
RELATIVELY WEAK LOW-LEVEL SHEAR MAY TEND TO LIMIT THE POTENTIAL FOR
TORNADOES UNTIL LATER THIS EVENING WHEN LLJ IS FORECAST TO
STRENGTHEN.

Looks like a long night David. FWD did a special sounding at 18Z.

Have our first watch of the year. Took 20 days.
