AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
919 PM CDT THU SEP 17 2009
.DISCUSSION...NO CHANGES MADE TO THE FORECAST. THE FORECAST REMAINS
ON TRACK WITH HIGHEST POPS OVER WC/NWRN ZONES. WILL ALSO ALLOW THE
FLASH FLOOD WATCH TO CONTINUE.
&&
.PREV DISCUSSION...300 PM CDT THU SEP 17 2009 TONIGHT THROUGH
SATURDAY NIGHT...STILL LOOKING AT DECENT RAIN CHANCES THROUGH THE
SHORT TERM AS WE REMAIN UNDER THE INFLUENCE OF THE NEARLY STACKED
LOW PRESSURE SYSTEM TO OUR WEST. THIS LOW PRESSURE SYSTEM THAT WAS
NOTED OVER EAST TEXAS THIS MORNING IS NOW MOVING EAST AGAIN AND IS
BACK INTO WESTERN LOUISIANA. THIS LOW PRESSURE SYSTEM HAS WEAKENED
AND MODELS AGREE THAT THE LOW WILL CONTINUE WEAKENING TONIGHT AS IT
APPROACHES OUR CWA. THE MID TO UPPER LEVEL PORTION OF THE SYSTEM
WILL LIFT NORTHEAST ACROSS OUR CWA FRIDAY AS AN OPEN TROUGH WHILE
THE ASSOCIATED SURFACE LOW LINGERS OVER OUR EAST CENTRAL LOUISIANA
PARISHES THROUGH FRIDAY NIGHT BEFORE MOVING TO THE NORTH SATURDAY.
FOR TONIGHT...OUR AIRMASS REMAINS QUITE MOIST(JAN 12Z THU PW OF
1.83IN) BUT WITH LIGHT DEEP LAYER SHEAR AND WEAK LAPSE RATES. HEAVY
RAINFALL POTENTIAL WILL REMAIN THE MAIN CONCERN WITH ANY
THUNDERSTORM ACTIVITY. DAYTIME HEATING HAS LED TO THE DEVELOPMENT OF
SHOWERS AND THUNDERSTORMS OVER MUCH OF THE AREA. THERE REMAINS THE
CONCERN FOR FLASH FLOODING OVER PORTIONS OF OUR DELTA REGION THAT
RECEIVED VERY HEAVY RAINFALL EARLIER IN THE WEEK. ALTHOUGH FLASH
FLOOD GUIDANCE HAS COME UP RECENTLY DUE TO LIGHTER AMOUNTS DURING
THE LAST DAY OR SO...EL DORADO IN SE ARKANSAS RECORDED NEARLY TWO
INCHES IN AN HOUR JUST BEFORE NOON. OUR FLASH FLOOD WATCH WILL BE
EXTENDED THROUGH THIS EVENING FOR THE SAME AREA TO ACCOUNT FOR THE
HIGH RAINFALL RATES. THE FLASH FLOOD WATCH MAY BE EXTENDED INTO
FRIDAY BUT LOWER RAINFALL RATES ARE EXPECTED OVER OUR NORTHWEST.
MODEL GUIDANCE MIN TEMPS HAVE BEEN RUNNING TOO COOL LATELY AND
CONSIDERING LINGERING CLOUD COVER AND RAIN CHANCES WL GO SEVERAL
DEGREES ABOVE GUIDANCE AT MOST SITES TONIGHT. MOST SITES WILL BOTTOM
OUT IN THE LOWER 70S AGAIN FRIDAY MORNING.
WITH OUR WARM MOIST AIRMASS IN PLACE...SURFACE LOW OVER OUR WESTERN
ZONES AND AN UPPER TROUGH OVERHEAD...DAYTIME HEATING WILL LEAD TO
THE DEVELOPMENT OF NUMEROUS SHOWERS AND SCATTERED THUNDERSTORMS
AGAIN FRIDAY. GUIDANCE MAX TEMPS WERE CLOSE AND MOST SITES WILL TOP
OUT IN THE MID 80S WITH SOME NORTHERN LOCATIONS HELD TO THE LOWER
80S. BY FRIDAY NIGHT THE UPPER TROUGH WILL BE MOVING NORTHEAST OF
OUR CWA ALTHOUGH OUR FLOW ALOFT WILL BACK TO SOUTHWESTERLY IN
RESPONSE TO A SECOND UPPER TROUGH OVER THE SOUTHERN PLAINS. THE WEAK
SURFACE LOW WILL LINGER OVER OUR WEST FRIDAY NIGHT INTO SATURDAY
BEFORE A DISTURBANCE IN THE SOUTHWEST FLOW ALOFT HELPS LIFT THE
SURFACE LOW OUT TO THE NORTH NORTHEAST. THE DISTURBANCE ALOFT WILL
COMBINE WITH THE SURFACE LOW...OUR MOIST AIRMASS AND DAYTIME HEATING
TO DEVELOP A DECENT COVERAGE OF CONVECTION AGAIN SATURDAY. THE BULK
OF THE CONVECTION WILL END IN THE WAKE OF THE SURFACE LOW SATURDAY
EVENING ALTHOUGH A FEW LINGERING SHOWERS WILL BE POSSIBLE IN THE
EAST THROUGH THE NIGHT. /22/
.LONG TERM...SUNDAY THROUGH WEDNESDAY...DEEP LOW PRESSURE FROM OVER
THE GULF OF ALASKA WILL EJECT AN UPPER TROUGH EASTWARD OVER THE
PACIFIC NORTHWEST...WHICH WILL BE AMPLIFYING SUNDAY AS UPPER LEVEL
JET ENERGY DIVES SOUTHWARD INTO THE BACKSIDE OF THE TROUGH. ON
SUNDAY...THE COMBINATION OF THE AMPLIFYING UPPER TROUGH IN THE LEE
OF THE ROCKIES AND AN AMPLIFYING UPPER RIDGE OVER THE APPALACHIANS
WILL FORCE THE UPPER LEVEL ZONAL JET MAX OVER THE CWA TO GRADUALLY
BECOME MORE CYCLONICALLY CURVED...WITH UPPER FLOW BACKING TO MORE
SOUTHWESTERLY AND EVEN BECOMING SOMEWHAT DIFFLUENT AS UPPER LEVEL
ENERGY LIFTS NORTHEASTWARD UPSTREAM OF THE UPPER RIDGE AXIS.
MID/UPPER-LEVEL Q-VECTOR CONVERGENCE CORRESPONDINGLY INCREASES
ACROSS THE AREA ON SUNDAY...ALONG WITH A SLIGHT INCREASE IN PWATS AS
MID/UPPER LEVEL MOISTURE OVER THE WESTERN GULF IS ADVECTED INTO THE
REGION. THUS... PRECIP CHANCES CONTINUE INTO SUNDAY...ESPECIALLY AS
APPRECIABLE SOUTH TO SOUTHEAST LOW LEVEL RETURN FLOW DEVELOPS WEST
OF THE BUILDING HIGH OVER THE EASTERN CONUS. HOWEVER...THE EARLIER
SURFACE TROUGH WILL LIKELY HAVE LIFTED NORTH OF THE AREA BY SUNDAY
AFTERNOON...PROVIDING ONLY LIMITED LOW LEVEL FORCING FOR CONVECTION.
THINGS GET RATHER INTERESTING AS AN EVEN DEEPER GULF OF ALASKA
VORTEX IS PROGGED TO INTERACT WITH AN AMPLIFYING EAST PACIFIC RIDGE
THIS WEEKEND TO CREATE AN INTENSE H2 ZONAL JET STREAK OVER THE GULF
OF ALASKA BY SUNDAY. OPERATIONAL GFS/ECMWF ARE SHOWING THE H2 JET
STREAK REACHING OVER 115 KT OVER THE PACIFIC NORTHWEST. THE
QUASI-HORIZONTAL ZONAL MOMENTUM IN THIS JET STREAK APPEARS TO BE SO
STRONG...AT LEAST BASED ON THE OPERATIONAL GFS AND ECMWF...THAT IT
COULD CUT OFF THE SOUTHERN EXTENSION OF THE AMPLIFYING UPPER TROUGH
BY MONDAY...YIELDING A CLOSED UPPER-LEVEL CYCLONIC CIRCULATION
SOMEWHERE IN THE LEE OF THE ROCKIES BY LATE MONDAY...WHICH WILL
MERGE WITH THE ALREADY PRESENT AND WEAKER UPPER LOW CURRENTLY OVER
THE EASTERN ROCKIES. THIS COULD YIELD A SPLIT-FLOW REGIME OVER THE
EASTERN TWO-THIRDS OF THE CONUS...WITH A JET STREAM BRANCH OVER THE
NORTHERN CONUS AND SOUTHERN CANADA AND A SECONDARY BRANCH AROUND THE
CLOSED CYCLONIC CIRCULATION BY TUESDAY. ADDITIONAL PIECES OF
SHORTWAVE ENERGY DIVING INTO THE BACKSIDE OF THE NORTHERN TROUGH
COULD FEED INTO THE CLOSED CIRCULATION...THOUGH MODELS TYPICALLY
DON/T HANDLE THESE IMPULSES WELL ALONG WITH THE CUT-OFF CIRCULATIONS
IN EXTENDED PERIODS...AND THUS FORECAST CONFIDENCE BEYOND MONDAY
WANES RATHER FAST. CONSIDERABLE SPREAD EXISTS AMONG GFS ENSEMBLE
PERTURBATIONS...OPERATIONAL GFS...AND ECMWF. WHILE THE OPERATIONAL
GFS AND ECMWF BOTH INDICATE A RATHER DEEP CLOSED CYCLONIC
CIRCULATION BY TUESDAY NIGHT OVER THE PLAINS STATES...SEVERAL GFS
ENSEMBLE PERTURBATIONS STILL INDICATE AN OPEN TROUGH...WITH OTHER
MEMBERS SHOWING A CLOSED CIRCULATION WELL TO THE EAST OF THE
OPERATIONAL RUN. THE EXACT SYNOPTIC SET-UP FOR THE MIDDLE OF NEXT
WEEK WILL HIGHLY MODULATE THE LOCATION OF ANY ENHANCED CONVECTIVE
ACTIVITY...AS WELL AS THE POTENTIAL FOR HEAVY RAINFALL AND STRONG
STORMS. HOWEVER...MODEL CONSENSUS IS THAT SOUTHWESTERLY FLOW ALOFT
WILL BE INCREASING LATE IN THE WEEKEND INTO THE EARLY PART OF NEXT
WEEK...WITH INCREASING SYNOPTIC-SCALE ASCENT ACROSS THE AREA.
THUS FOR MONDAY...SOUTHWESTERLY FLOW ALOFT INCREASES AS THE
AFOREMENTIONED UPPER-LEVEL TROUGH AND/OR CLOSED CIRCULATION
TRANSLATES EASTWARD TOWARD THE EASTERN CONUS/WESTERN ATLANTIC UPPER
RIDGE. INCREASING MID/UPPER-LEVEL Q-VECTOR CONVERGENCE ACROSS THE
AREA EAST OF THE TROUGH AXIS WILL ALLOW COVERAGE OF PRECIP TO EXPAND
FOR MONDAY...ESPECIALLY WITH LITTLE CAP AND PWATS AROUND 1.9 INCHES.
FOR TUESDAY...SOUTHWESTERLY FLOW ALOFT CONTINUES WITH PWATS
POTENTIALLY FURTHER INCREASING AHEAD OF ANY FRONTAL FEATURES...WITH
DEEP-LAYER SYNOPTIC ASCENT INCREASING A LITTLE MORE RESULTING IN
CONTINUING PRECIP CHANCES.
A STRONG COLD FRONT ASSOCIATED WITH THE AMPLIFYING UPPER TROUGH
COULD BE MOVING SOUTHEASTWARD ACROSS THE CONUS ON MONDAY AND
TUESDAY. THE OPERATIONAL GFS...WHICH DEEPENS THE UPPER CLOSED LOW
SIGNIFICANTLY...FORMS A FRONTAL WAVE ALONG THE COLD FRONT OVER NORTH
TEXAS...WHICH THEN OCCLUDES OVER ARKANSAS TUESDAY NIGHT WHILE A COLD
FRONT MOVES ACROSS THE AREA ON WEDNESDAY. THE 16/1200 UTC RUN OF THE
ECMWF SHOWED A MUCH WEAKER FRONTAL WAVE THAT ESSENTIAL TRANSLATES
EASTWARD WITH THE FRONT...THOUGH THE TIMING IS NOT CONSIDERABLY
DIFFERENT THAN THAT FROM THE OPERATIONAL GFS RUN FROM 17/0000 UTC.
THEN THE 17/0000 UTC RUN OF THE ECMWF CAME IN WITH A GRADUAL SURFACE
WIND SHIFT TO NORTHEAST FOR WEDNESDAY...THE CLOSED CIRCULATION OVER
THE SOUTHWEST CONUS...AN UPPER RIDGE OVER THE CWA...AND ALMOST NO
PRECIP FOR WEDNESDAY. ULTIMATELY...THE TIMING AND STRENGTH OF THE
SURFACE FEATURES THIS FAR SOUTH...IF ANY...WILL BE HIGHLY MODULATED
BY THE UPPER LEVEL DYNAMICS OF THE SOUTHERN EXTENSION OF THE UPPER
TROUGH...FOR WHICH RATHER LOW CONFIDENCE EXISTS FOR TUESDAY THROUGH
THURSDAY. THIS IS ESPECIALLY THE CASE...AS A NUMBER OF PERTURBATION
MEMBERS OF THE GFS ENSEMBLE SHOW THE AREA ON THE BACKSIDE OF THE
UPPER TROUGH FOR THIS TIME...KEEPING PRECIP CHANCES RATHER LOW...AS
DOES THE LATEST ECMWF. YET...THE OPERATIONAL GFS KEEPS THE UPPER LOW
NORTHWEST OF THE AREA...WITH AT LEAST SOME MID/UPPER-LEVEL Q-VECTOR
CONVERGENCE PERSISTING. WHILE THE OPERATIONAL GFS DEPICTS DEEP
MOISTURE AND PRECIP CHANCES LINGERING BEHIND THE SURFACE FRONT...THE
LATEST ECMWF DOES NOT GIVEN HOW FAR WEST IT KEEPS THE UPPER LOW. THE
GFS APPEARS TO BE AN OUTLIER IN ITS DEPICTION OF MORE WIDESPREAD
PRECIP FOR WEDNESDAY...WITH THE ECMWF ALSO AN OUTLIER ON THE DRY
SIDE. THE ENTIRELY DRY ECMWF SOLUTION HAS BEEN DISCOUNTED FOR
WEDNESDAY GIVEN ITS POOR RUN-TO-RUN CONTINUITY FOR THE PLACEMENT OF
THE CLOSED UPPER LOW.
GENERALLY...THOUGH WITH A FEW EXCEPTIONS...MAV/MEX POPS HAVE BEEN
FOLLOWED FOR THE ENTIRE PERIOD. HOWEVER...POPS WERE TRENDED DOWNWARD
FROM THE MEX IN A FEW CASES...PARTICULARLY ON SUNDAY...WHEN MEX POPS
EXCEEDED MEH POPS AND OVERALL SYNOPTIC FORCING APPEARS TO BE
WEAK...AND PRECIP WILL MORE LIKELY BE DRIVEN BY DIURNAL HEATING
CYCLE. WEDNESDAY POPS ALSO WERE TRENDED DOWNWARD FROM THE MEX AS
THE OPERATIONAL GFS QPF FIELDS APPEAR TO BE AN OUTLIER AT THE HIGH
SIDE OF GUIDANCE SUITE...WITH POPS TRENDED TOWARD THE MEH INSTEAD.
SLIGHT CHANCE POPS CONTINUE INTO THURSDAY BASED ON A SIMILAR BLEND.
FORECAST TEMPERATURES THROUGH THE PERIOD FOLLOW MAV/MEX GUIDANCE
RATHER CLOSELY AS WELL...BUT HIGH TEMPS WERE TRENDED DOWNWARD FROM
MEX FOR TUESDAY AND WEDNESDAY...GIVEN CONVECTIVE COVERAGE AND
LIMITED INSOLATION...AS WELL AS POTENTIAL FRONTAL PASSAGE.
AS FAR AS HAZARDS FROM STORMS ON SUNDAY THROUGH WEDNESDAY ARE
CONCERNED... THREAT OF HEAVY RAIN WILL CONTINUE WITH PLENTIFUL
MOISTURE TRANSPORT INTO THE AREA WITH EFFICIENT RAINFALL RATES.
STORM MOTIONS WILL BE INCREASED FOR SUNDAY THROUGH WEDNESDAY...WHICH
COULD MITIGATE FLASH FLOOD POTENTIAL SOMEWHERE. HOWEVER...ANTECEDENT
HEAVY RAINFALL AND SATURATED SOILS WILL RAISE SOME CONCERN FOR FLASH
FLOODING AND THEREFORE THE THREAT WILL NEED TO BE MONITORED CLOSELY.
BEHIND ANY FRONT FOR LATE WEDNESDAY INTO THURSDAY...THREAT FOR FLASH
FLOODING WOULD DIMINISH SOMEWHAT THEN. STRENGTH OF DEEP LAYER SHEAR
COULD SUPPORT STRONG STORMS DURING THIS TIME AS WELL...ESPECIALLY
ALONG AND AHEAD OF ANY FRONT FOR TUESDAY...BUT RATHER WIDESPREAD
CONVECTIVE COVERAGE AND ASSOCIATED CONVECTIVE OVERTURNING...AND
POTENTIAL FOR DEEP SHEAR TO BE DISASSOCIATED FROM HIGHER INSTABILITY
IF THE UPPER LOW CUTS OFF TOO EARLY...ADDS CONSIDERABLE UNCERTAINTY
FOR STRONG THUNDERSTORM POTENTIAL NEXT WEEK DESPITE INCREASING DEEP
SHEAR. /COHEN/
