AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
212 PM CDT THU APR 18 2013
.DISCUSSION...
CURRENTLY ANTICIPATED COLD FRONT WAS JUST EAST OF THE LITTLE ROCK
METRO AREA WITH NARROW BAND OF THUNDERSTORMS THAT HAVE HAD
TENDENCIES TO BOW OUT...BUT STRUGGLING TO BECOME MORE ACTIVE. CLOUD
COVER REMAIN BROKEN OUT AHEAD OF THE LINE WHICH HAS HELD
TEMPERATURES...WHILE LATEST MSU SOUNDING TAKEN IN NORTHERN COAHOMA
COUNTY MISSISSIPPI NOT IMPRESSIVE IN REGARDS TO LAPSE RATES AND
INSTABILITY...AS A REFLECTION OF THE CAP OFF THE 12Z JACKSON MS HAS
NOSED INTO THE REGION. EVEN THOUGH DEWPOINTS HAVE INCREASED A DEGREE
OR TWO CAPE AMOUNTS OVER THE AREA WERE ONLY AROUND 500 J/KG...LESS
THAN THE NAM AND GFS HAS FORECASTED FOR 18/18Z. THUS INFLUENCES FROM
THE MAIN CENTRAL PLAINS TROUGH IS LAGGING AND ANY SURFACE BASED
CONVECTION IN THE WARM SECTOR WILL EITHER BE DELAYED SOME OR BECOME
NONEXISTENT IN THE MODERATE RISK AREA. EARLIER DISCUSSION FROM SPC
HINTED THAT THIS REGION/DELTA COUNTIES WOULD BE MOST FAVORABLE FOR
SEVERE WEATHER AND A NEW TORNADO WATCH BOX HAS BEEN ISSUED JUST THE
SOUTH OF THE COUNTY WARNING AREA. NOT SURE HOW INTENSE OF A THREAT
STILL REMAINS IN WEST TENNESSEE AND NORTH MISSISSIPPI. STILL FEEL
THAT ISOLATED MINI BOWING SEGMENTS OF DAMAGING WINDS WITH THE
FRONTAL SQUALL LINE WILL BE THE GREATEST THREAT FOR THE AREA. AND
THE POSSIBILITY OF A SIGNIFICANT/STRONG TORNADO APPEARS UNLIKELY
NOW. HAVE DISCUSSED THESE LIMITING FACTORS WITH COLLEAGUES AND
AGREED ON LOWERING THE MODERATE RISK FOR OUR AREA DOWN TO A SLIGHT
RISK. AN UPDATED HWO WILL BE OUT SHORTLY. TIMING OF THE BOUNDARY
HAS NOT CHANGED PASSING THROUGH THE MEMPHIS METRO IN THE 4-6PM
TIME FRAME AND CROSSING THE TENNESSEE RIVER AROUND 9-11PM.
STRONGER WINDS HAVE OCCURRED WITH THE 60 KT LOW LEVEL JET WITH GUSTS
TO NEAR 50 MPH OVER NORTHEAST ARKANSAS TODAY. THIS FEATURE WILL
CONTINUE TO SHIFT EAST THIS EVENING AHEAD OF THE FRONT. THE CURRENT
WIND ADVISORY WILL LIKELY BE CANCELLED IN THE 00Z TIME FRAME WEST OF
THE MS RIVER AND NEAR 03Z OVER THE EAST. A BAND OF SHOWERS AND A FEW
STORMS WILL CONTINUE ON THE COLD SIDE OF THE BOUNDARY
OVERNIGHT...WITH TOTAL QPF AMOUNTS GENERALLY IN THE ONE INCH RANGE.
FRIDAY THROUGH SUNDAY...CLOUDS WILL EXIT THE AREA FRIDAY MORNING AS
HIGH PRESSURE BUILDS IN FROM THE PLAINS. WEST WINDS WILL BECOME
BREEZY WITH HIGHS IN THE 50S TO LOW 60S. AS THE HIGH CENTER PASSES
OVER THE AREA FRIDAY NIGHT WINDS WILL DIMINISH UNDER CLEAR SKIES AND
PATCHY FROST WILL BE POSSIBLE ACROSS THE NORTH AND EAST AS
TEMPERATURES DIP INTO THE MID 30S. A FROST ADVISORY MAY BE NEEDED
FOR THIS REGION. A BROAD TROUGH WILL REMAIN OVER THE MIDDLE OF THE
COUNTRY ON SATURDAY AND SUNDAY WITH SOME INCREASE IN HIGH LEVEL
MOISTURE. TEMPERATURES WILL REMAIN COOLER THAN AVERAGE...BUT
PLEASANT WITH HIGHS IN THE 60S TO NEAR 70...COUPLED WITH LOWER
HUMIDITIES.
MONDAY THROUGH WEDNESDAY...AS WINDS TURN SOUTHERLY THE GFS BRINGS A
SLIGHT INCREASE IN GULF MOISTURE AHEAD OF A REINFORCING COLD FRONT
ON MONDAY. SHOWERS AND STORMS SEEM REASONABLE LATE MONDAY NIGHT AND
THROUGH WEDNESDAY MORNING WITH THIS SYSTEM BUT ANY SEVERE WEATHER
IS STILL IN QUESTION. HAVE NOT CHANGED THE FORECAST FROM THE NIGHT
CREW'S THINKING DURING THIS PERIOD. TEMPERATURES SHOULD BE CLOSE TO
AVERAGE...COOLING AGAIN BEHIND THE FRONT ON WEDNESDAY.

.AVIATION...
18Z TAF CYCLE
LARGE SCALE UPPER TROUGH ORIENTED IN A POSITIVELY TILTED NATURE IS
PUSHING EAST INTO THE LOWER MISSISSIPPI VALLEY THIS AFTERNOON. A
LINE OF SHOWERS AND THUNDERSTORMS HAS DEVELOPED ALONG A COLD FRONT
TO OUR WEST...BUT SO FAR HAVE REMAINED BELOW SEVERE LIMITS. LATEST
MISSISSIPPI STATE EXPERIMENTAL SOUNDING SAMPLING AN ONLY
MARGINALLY UNSTABLE AIRMASS SO FAR ACROSS NORTHWEST MISSISSIPPI.
AS THE TROUGH HANGS BACK TO THE SOUTHWEST...MAY TEND TO LIMIT
INTENSITY OVERALL AS THE CONVECTIVE LINE MOVES THROUGH AT
KJBR...KMKL. THERE APPEARS TO BE GREATER SURFACE HEATING AND
MOISTURE ADVECTION POTENTIAL FROM KMEM SOUTHWARD...SO HIGHEST
POTENTIAL FOR ANY SEVERE CONVECTION WOULD BE AT THE KMEM AND KTUP
SITES. AS FOR TIMING...APPEARS LINE WILL MOVE ACROSS THE TAF SITES
FROM WEST TO EAST FROM LATE AFTERNOON THROUGH THE EVENING
HOURS...WITH SEVERAL HOURS OF POST FRONTAL CONVECTION EXPECTED.
CIGS WILL BECOME MVFR WITH THE PASSAGE OF THE FRONT AND STORMS AND
REMAIN SO FOR SEVERAL HOURS POST FRONTAL. SOUTH WINDS SUSTAINED
NEAR 20 KTS WILL GUST AT TIMES TO NEAR 30 KTS AT THE
SURFACE...WITH NEAR 50 KTS OBSERVED AROUND 3 KFT. THIS COULD
CONTINUE COMPRESSIONAL ISSUES AT THE AIRPORTS UNTIL FRONTAL
PASSAGE.
AFTER THE FRONT MOVES THROUGH EXPECT WINDS TO TURN NORTHWESTERLY
AT 15 KTS WITH GUSTS TO 25 KTS BEFORE DIMINISHING LATER TONIGHT.
CIGS SHOULD BECOME VFR AGAIN LATER TONIGHT AND CONTINUING INTO
FRIDAY MORNING.
