Area forecast discussion, Apr 4, 4:10 AM CDT, 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
410 AM CDT FRI APR 4 2014

...SEVERE STORMS POTENTIAL ONGOING THIS MORNING...

.SHORT TERM...TODAY THROUGH SATURDAY NIGHT...LOCAL RADARS ARE LIT UP
THIS MORNING WITH A LINEAR MCS JUST OUT RUNNING AN APPROACHING COLD
FRONT. AT THIS WRITING STORMS STRETCHED FROM BASTROP TO GREENWOOD
AND THE MCS WILL SPREAD EAST SOUTHEAST ACROSS MUCH OF THE CWA THIS
MORNING WITH THE TRAILING COLD FRONT ARRIVING IN THE DELTA BEFORE
SUNRISE. THE AIRMASS AHEAD OF THE MCS WAS WARM AND MOIST AS
TEMPERATURES WERE STILL RUNNING IN THE LOWER 70S AND THE BLENDED
TOTAL PW PRODUCT SHOWING A PLUME OF 1.6IN PWS. ADEQUATE INSTABILITY
ALONG WITH STRONG AND FAVORABLE SHEAR WILL MAINTAIN THE POTENTIAL
FOR SEVERE STORM DEVELOPMENT. THE PRIMARY THREAT WILL BE DAMAGING
WINDS BUT A FEW TORNADOES AND HAIL THE SIZE OF QUARTERS WILL REMAIN
POSSIBLE AS WELL. THIS ACTIVITY WILL DROP INTO THE CENTRAL PORTIONS
OF OUR CWA BY DAYBREAK. SOME HI-RES MODELS SUGGEST THE ACTIVITY WILL
WEAKEN LATER THIS MORNING WITH A POTENTIAL INCREASE IN DEVELOP THIS
AFTERNOON OVER OUR SOUTHEAST ALONG THE COLD FRONT BEFORE IT EXITS
OUR CWA. WL MAINTAIN MENTION OF THIS POTENTIAL IN THE HWO FOR TODAY.
THE COLD FRONT WILL BE SOUTH OF OUR CWA THIS EVENING BUT STALL NEAR
THE GULF COAST AS IT BECOMES NEARLY ALIGNED WITH THE FLOW ALOFT.
DRIER AIR WILL MOVE INTO OUR CWA IN THE WAKE OF THE COLD FRONT AND A
1023MB SURFACE HIGH WILL MOVE OVER THE MID MISSISSIPPI VALLEY FROM
THE SOUTHERN PLAINS AND SPREAD ACROSS OUR CWA. THIS WILL HELP SEND
MORNING LOWS SATURDAY BACK BELOW NORMAL IN THE 40S AT MOST SITES.
COOLER THAN NORMAL TEMPERATURES WILL CONTINUE SATURDAY BUT THE DRY
WEATHER WON'T LAST LONG AS ANOTHER POTENT DISTURBANCE OVER THE
DESERT SOUTHWEST APPROACHES BACKING OUR WINDS ALOFT AND SENDING
MOISTURE BACK INTO OUR CWA. MODELS ARE IN FAIR AGREEMENT THAT RAIN
WILL WORK BACK INTO OUR SOUTHERN ZONES SATURDAY AFTERNOON AND
CONTINUE INCREASING IN COVERAGE AND INTENSITY SATURDAY NIGHT. BY
SUNDAY MORNING PWS WILL BE BACK TO AN INCH AND A HALF ALONG THE
HIGHWAY 84 CORRIDOR AND A FEW RUMBLES OF THUNDER WILL BE HEARD AS
FAR NORTH AS THE INTERSTATE 20 CORRIDOR DUE TO SOME ELEVATED
INSTABILITY. /22/

.LONG TERM...SUNDAY THROUGH FRIDAY...THE MAIN CONCERN IN THE LONG
TERM REMAINS THE NEXT SYSTEM THAT WILL AFFECT THE REGION SUNDAY INTO
MONDAY.

THE FRONT WILL BE SITUATED ALONG THE GULF COAST SUNDAY MORNING.
SOUTHWEST MID LEVEL FLOW WILL BE ACROSS THE REGION AS A TROUGH
DEVELOPS OUT WEST. A 1006MB SFC LOW WILL START TO DEVELOP ACROSS THE
GULF OF MEXICO NEAR THE SOUTHERN TEXAS COAST. THROUGH THE
DAY...MOISTURE WILL INCREASE ACROSS THE REGION AS ISENTROPIC LIFT
INCREASES...BRINGING SHOWERS AND SOME THUNDERSTORMS TO THE REGION
AND OVERSPREAD FROM SOUTH TO NORTH THROUGH THE DAY. THE GREATEST
COVERAGE OF PRECIPITATION WILL BE IN THE SOUTH WHERE MOISTURE
CONTENT WILL BE HIGHEST PER MODEL PRECIPITABLE WATER VALUES(1.7-1.8
INCHES AROUND THE HIGHWAY 84 CORRIDOR BY SUNDAY EVENING VERSUS
1.4-1.5 INCHES ACROSS THE HIGHWAY 82 CORRIDOR). MODELS HAVE REMAINED
IN VERY GOOD AGREEMENT ABOUT THE DEPTH AND TRACK OF THE SFC LOW AS
IT DEVELOPS IN THE GULF ON SUNDAY AND TRACKS TO THE NORTH AND EAST
THROUGH THE DAY AND EVENING HOURS. THE ONLY OUTLIER AT THIS TIME IS
THE NAM IN EXITING THE LOW QUICKER THAN THE OTHER MODELS ON
MONDAY...BUT ALL OTHER GLOBAL MODELS HAVE BECOME MORE CONSISTENT
WITH EACH OTHER AND FROM RUN TO RUN.

SUNDAY EVENING THE SFC LOW WILL TRACK GENERALLY UP ACROSS THE
NATCHEZ TRACE CORRIDOR. GIVEN THIS NORTHERN TRACK...THERE WILL
REMAIN SOME CONCERN FOR SEVERE WEATHER GIVEN PLENTY OF WIND SHEAR
AVAILABLE(30-45KTS OF 0-1KM) AND GOOD HELICITY VALUES. VERTICAL
TOTALS REMAIN A LITTLE LESS ROBUST BUT THESE INCREASE THROUGH THE
EVENING AND OVERNIGHT HOURS. ALL OF THIS WOULD BE IN THE
SOUTH/SOUTHEAST PORTIONS OF THE CWA. THIS COULD START DURING THE
AFTERNOON BUT LOOKS LIKE THE BEST INGREDIENTS WOULD BE IN THE
EVENING HOURS AND LATER. A DECENT LOW LEVEL JET KICKS IN DURING THE
NIGHTTIME HOURS WITH 40-50KTS AND THIS WILL ALSO HELP BRING IN MORE
MOISTURE TO THE REGION. PW VALUES INCREASE TO AROUND 1.8-1.9 INCHES
THROUGH THE NIGHT WHICH IS 2-3 STANDARD DEVIATIONS ABOVE NORMAL.
WHILE SEVERE WEATHER IS A CONCERN...HEAVY RAIN AND FLOODING WILL BE
THE BIGGEST CONCERN. THERE IS EVEN SOME QUESTION THAT SINCE THERE
COULD BE QUITE A BIT OF RAINFALL...HOW WILL THIS AFFECT SEVERE
POTENTIAL. BUT AS FOR RAINFALL...HIGH MOISTURE CONTENT WILL LEAD TO
HEAVY DOWNPOURS. CIPS ANALOGS DEPICT A DECENT PROBABILITY FOR
GREATER THAN 5 INCHES OF RAIN IN THE SOUTH ESPECIALLY. WILL CONTINUE
TO DEPICT THIS IN THE HWO AND LIKELY START IN THE GRAPHICS.

THE SFC LOW WILL MOVE OUT MONDAY MORNING AND RAIN DEPARTS TO THE
EAST. THE SHORTWAVE TROUGH WILL EXIT THE REGION AS WELL BUT A LARGER
SCALE UPPER TROUGH WILL REMAIN SET UP OVER THE REGION AS A LARGE
RIDGE DEVELOPS OVER THE WEST COAST. ANOTHER DISTURBANCE WILL MOVE
ACROSS THE REGION ON TUESDAY AND SQUEEZE WHATEVER MOISTURE IS LEFT
FROM THE ATMOSPHERE. FOLLOWING THIS PASSAGE...MUCH COOLER AND DRIER
AIR WILL MOVE INTO THE REGION AS PW VALUES DROP BELOW AN INCH...EVEN
DROPPING TO AROUND 0.50 INCHES.

THE REMAINDER OF THE PERIOD WILL BE FAIRLY QUIET AND WILL ALLOW THE
REGION TO DRY OUT FROM RECENT RAINFALL. THE UPPER TROUGH WILL DEPART
OFF TO THE EAST AND BROAD RIDGING TO SEMI-ZONAL FLOW WILL MOVE IN.
BROAD SFC HIGH PRESSURE WILL BE PRESENT AT THE SFC AND ALL OF THIS
WILL LEAD TO DRY...QUIET WEATHER. TEMPERATURES WILL BE ON THE COOL
SIDE FOLLOWING THE COLD FRONT ON MONDAY AS THE UPPER TROUGH LINGERS.
HIGHS WILL BE IN THE 60S AND LOWS IN THE 40S. TEMPERATURES WILL
SLOWLY MODERATE BACK INTO THE 70S FOR HIGHS BY THE END OF THE WORK
WEEK GIVEN THE PATTERN CHANGE.

FOR SUNDAY...WENT COOLER FOR THE HIGHS IN THE DELTA GIVEN THE
INCREASING CLOUDS AND RAIN. THINK THIS AREA WILL NOT BE ENOUGH IN
THE WARM SECTOR TO OFFSET THIS BY WARM ADVECTION. FURTHER
SOUTH...TEMPERATURES SHOULD STILL BE ON THE WARMER SIDE GIVEN THE
INCREASING WARM ADVECTION. ALSO INCREASED POPS ON SUNDAY AND MONDAY
PER INCREASING CONFIDENCE IN WIDESPREAD RAIN. /28/

&&

.AVIATION...WIDESPREAD MVFR CIGS WERE BEING OBSERVED AT 09Z. A
BOWING LINE OF STRONG TO SEVERE TSTMS WERE NOTED AT 09Z FROM JUST
EAST OF GWO TO JUST NORTHWEST OF TVR. THIS ACTIVITY WILL SPREAD EAST
SOUTHEAST THIS MORNING AND AFFECT HKS-JAN-GTR AND EVENTUALLY
MEI-HBG. STRONG GUSTY SOUTH WINDS CAN BE EXPECTED AHEAD OF THE TSTMS
WITH A SHIFT TO THE WEST AS THE LINE MOVES THROUGH. A COLD FRONT
WILL FOLLOW THIS LINE OF CONVECTION AND PUSH SOUTH OF THE AREA BY
LATE AFTN. LIGHTER NORTHERLY WINDS AND VFR CONDS WILL DEVELOP IN THE
WAKE OF THE FRONT AND PREVAIL THROUGH TONIGHT. RAIN AND LOWER CONDS
WILL RETURN FROM THE SOUTH SATURDAY. /22/
