AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
402 PM CDT WED MAR 14 2012

.SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT...PERSISTENT CLOUD COVER
HAS HAMPERED TEMPERATURES THIS AFTERNOON. SATELLITE IMAGERY
INDICATES THAT CLOUDS ARE BREAKING UP BUT THIS HAS BEEN RATHER SLOW
TO OCCUR. A CONSEQUENCE OF THAT...HIGHS HAVE ONLY MADE IT INTO THE
UPPER 70S/SLIGHTLY TOUCHING 80. THERE HAVE BEEN A FEW SHOWERS ACROSS
FAR NORTHEASTERN MISSISSIPPI AND A FEW MORE ROBUST CELLS IN NORTHERN
ALABAMA. MOST OF THESE WILL REMAIN OUT OF OUR CWA FOR THE AFTERNOON
AND EVENING BUT AN ISOLATED STORM IN THE EAST IS POSSIBLE AND COULD
BRIEFLY BECOME STRONG. DRY CONDITIONS OTHERWISE ARE EXPECTED TO
CONTINUE WITH ANOTHER NIGHT OF WARM TEMPERATURES AND STRATUS/FOG.
SREF VISIBILITY PROBS INDICATE THAT THERE COULD BE SOME PATCHY
FOG...BUT PROBS ARE NOT AS HIGH AS THEY HAVE BEEN PREVIOUS NIGHTS.
IN ADDITION...GFS BUFR SOUNDINGS INDICATE THERE MAY BE MORE STRATUS
THAN FOG....AND WINDS LOOK TO REMAIN SOMEWHAT UP THROUGH THE NIGHT
WHICH MAY HELP TO PRECLUDE THE DENSER FOG.

AFTER MIDNIGHT TONIGHT...MODELS INDICATE THE BEGINNINGS OF A
SHORTWAVE MOVING ACROSS THE UPPER FRINGES OF THE RIDGE. THIS MAY
BRING SOME SHOWERS TO THE FAR NORTHWESTERN AREAS OF THE CWA THROUGH
THE MORNING...BUT NOT EXPECTING MUCH IF ANYTHING. AS THE DAY
PROGRESSES...AND TEMPERATURES BEGIN TO HEAT UP...ADDITIONAL SHOWER
AND THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE AS THE SHORTWAVE
SLOWLY TRACKS ACROSS NORTHERN MISSISSIPPI AND WESTERN TENNESSEE.
THIS WILL ALSO COUPLE WITH A 200-300MB JET THAT IS AROUND 50-70KTS.
THIS COULD PROVIDE JUST ENOUGH FORCING...WHICH HAS BEEN LACKING
THESE PAST COUPLE OF DAYS...FOR A BETTER COVERAGE OF STORMS. THERE
IS THE POSSIBILITY THAT MOST OR EVEN ALL OF THIS COULD REMAIN JUST
TO THE NORTH OF THE CWA WHICH IS ALSO DEPICTED ON HI-RES WRF MODELS...BUT
ANY OUTFLOW BOUNDARIES COULD MAKE IT INTO MY NORTHERNMOST ZONES AND
BRING SOME CHANCE FOR SHOWERS AND STORMS. RIGHT NOW...WE ARE NOT
ADVERTISING ANY STRONG OR SEVERE WITH THIS BUT GIVEN ENOUGH
HEATING(ASSUMING CLOUDS CAN CLEAR SOONER THAN THEY DID
TODAY)...THERE WILL BE ENOUGH LAPSE RATE GIVEN COLD TEMPERATURES AT
500MB...AND SOME DCAPE FOR A HAIL AND WIND POTENTIAL. THE MAIN AREAS
FOR THIS LOOK TO BE ALONG AND NORTH OF THE HIGHWAY 82 CORRIDOR...BUT
SPC HAS INTRODUCED A 5% RISK FOR ALL AREAS ALONG AND NORTH OF THE
I-20 CORRIDOR. ANY ACTIVITY THAT DEVELOPS SHOULD BEGIN TO DIMINISH
THROUGH THE EVENING BUT HAVE LEFT SOME LINGERING ACTIVITY IN THE FAR
NORTH OVERNIGHT AND INTO FRIDAY.

AS FOR TEMPS...WARM CONDITIONS WILL CONTINUE WITH READINGS IN THE
80-85 DEGREE RANGE...ASSUMING WE DON'T GET HAMPERED BY CLOUDS LONGER
INTO THE DAY. OVERNIGHT LOWS WERE TRICKY. GUIDANCE INDICATES SOME
DRIER AIR ROTATING AROUND THE RIDGE AND INFILTRATING
PORTIONS...MAINLY THE EAST AND SOUTHEAST...OF THE CWA. GIVEN THAT
THE ENTIRE SOUTHEAST IS PRETTY WELL ENTRENCHED IN A MOIST
AIRMASS...MIXING HAS BEEN LIMITED TODAY TO DROP THE DEWPOINTS AND
STRATUS IS EXPECTED TONIGHT...I AM HESITANT TO COMPLETELY BUY OFF ON
THIS FOR TONIGHT AND GO AS LOW AS GUIDANCE INDICATES. HAVE GONE AHEAD AND
RAISED LOWS OUT OF AT LEAST THE MIDDLE 50S INTO AT LEAST THE LOWER
60S. GIVEN THE RECENT MORNING TRENDS...I COULD SEE IT BEING WARMER
THAN THIS...BUT DID NOT WANT TO GO TOO AGGRESSIVE. GUIDANCE WAS ALSO
LOW LIKE THIS FOR EACH MORNING THROUGH FRIDAY MORNING. WILL HAVE TO
ASSESS THIS IN LATER SHIFTS AS CONVECTION MAY ALLOW FOR COOLER
CONDITIONS EACH DAY. /28/

.LONG TERM...LONG TERM PORTION OF THE FORECAST WILL GENERALLY BE
QUIET WITH OUR REGION CONTROLLED BY AN UPPER RIDGE AXIS. MODELS
REMAIN IN SOLID AGREEMENT WITH THE UPPER RIDGE FEATURE OVER THE AREA
WHILE THE LARGE UPPER LOW WILL BE OVER THE WESTERN CONUS. THE UPPER
LOW DOESN'T LOOK TO PUSH EAST UNTIL MID WEEK WHICH WOULD HELP PUSH A
COOL FRONT NEAR THE CWA AND HELP TO INCREASE PRECIP CHANCES.

THE MAIN FORECAST ISSUE WILL BE TEMPS WHICH WILL REMAIN QUITE WARM
FOR MID MARCH. FORECAST GUID CONTINUES TO COME IN WITH HIGHS IN THE
80-85 DEGREE RANGE AND THOSE VALUES WERE GENERALLY FOLLOWED. /CME/

&&

.AVIATION...CEILINGS ARE CONTINUING TO GRADUALLY IMPROVE AT SITES
THIS AFTERNOON WITH MAINLY VFR CONDITIONS PREVAILING...WHILE WINDS
REMAIN SOUTH SOUTHWESTERLY BETWEEN 5-10 KNOTS.  ANOTHER ROUND OF
WIDESPREAD IFR CEILINGS ARE EXPECTED OVERNIGHT AND INTO EARLY
THURSDAY MORNING.  PATCHY FOG WILL ALSO BE POSSIBLE AROUND DAY BREAK
THURSDAY...WHICH COULD REDUCE VISIBILITIES TO IFR STATUS. /19/
