Area forecast discussion, Sep 3, 4:37 PM EDT, 2 hours 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
437 PM EDT SAT SEP 3 2011

.UPDATE...
THE AVIATION SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...

A COLD FRONT WILL SLIDE SOUTHEAST ACROSS CENTRAL INDIANA TONIGHT
BRINGING THUNDERSTORM CHANCES AND COOLER AIR. THE THUNDERSTORMS WILL
BE ENDING SUNDAY NIGHT. LABOR DAY WILL COOL AND DRY. THEN...THE
REMNANTS OF TROPICAL STORM LEE WILL LIFT NORTHEAST AND PROVIDE
SHOWER CHANCES BY MIDWEEK. LATE IN THE WEEK...THUNDERSTORMS WILL BE
POSSIBLE AS WELL. TEMPERATURES WILL MOSTLY BE IN THE 70S FOR
AFTERNOON HIGHS.

&&

.NEAR TERM /TONIGHT/...

MAIN CHALLENGE TO THE NEAR TERM WILL BE TIMING OF COVERAGE OF
THUNDERSTORMS ACROSS THE FORECAST AREA AS A COLD FRONT SLIDES
SOUTHEAST ACROSS CENTRAL INDIANA OVERNIGHT.

COMPLEX SURFACE PATTERN THIS AFTERNOON WITH A STATIONARY FROM THE
CENTRAL PLAINS TO NEAR THE MICHIGAN AND INDIANA BORDER.
MEANWHILE...ANOTHER FRONTAL SYSTEM WAS FROM THE UPPER MIDWEST TO THE
CENTRAL PLAINS AND IS EXPECTED TO BE THE DOMINATE SYSTEM THAT WILL
SLIDE ACROSS CENTRAL INDIANA OVERNIGHT. REGIONAL RADAR INDICATED
NUMEROUS THUNDERSTORMS ACROSS NORTHERN ILLINOIS...IOWA AND SOUTHWEST
ACROSS KANSAS SANDWICHED BETWEEN THE TWO FRONTS.

MODELS PRETTY CLOSE ON EVOLUTION OF THE SURFACE PATTERN AS THEY HAVE
THE DOMINATE CURRENTLY TRAILING COLD FRONT ACROSS NORTHWESTERN
INDIANA BY 06Z TONIGHT AND JUST TO THE SOUTH OF THE FORECAST AREA BY
12Z SUNDAY. MODELS ALSO AGREE ON RIBBON OF DEEPER MOISTURE TRAILING
THE COLD FRONT. BASED ON THAT...WILL GO LOWER THAN THE HIGH NAM POPS
TONIGHT BUT NOT QUITE AS LOW AS THE GFS MOS. THIS TRANSLATES TO GOOD
CHANCE POPS NORTHWEST AND CHANCE ELSEWHERE. PLENTY OF INSTABILITY
FOR THUNDER TONIGHT. MEANWHILE...STRONG UPPER TROUGH DIGGING SOUTH
FROM THE NORTHERN PLAINS TO THE WESTERN GREAT LAKES BY 12Z SUNDAY
WILL HELP INCREASE THE SHEAR ENOUGH ACROSS OUR NORTHWEST FORECAST
FOR POTENTIAL A SEVERE THUNDERSTORM OR TWO WITH DAMAGING WINDS AND
LARGE THE MAIN THREATS PER SPC DAY 1 OUTLOOK.

MOS LOW TEMPERATURES CLOSE AND LOOK OK.

&&

.SHORT TERM /SUNDAY THROUGH TUESDAY/...

FOCUS FOR THE SHORT TERM WILL BE THUNDERSTORM COVERAGE AND WHEN TO
PULL POPS ALONG WITH TEMPERATURES AS CANADIAN HIGH PRESSURE BUILDS
IN BEHIND THE COLD FRONT.

MODELS ALL IN DECENT AGREEMENT ON DEEPER MOISTURE ACROSS CENTRAL
INDIANA ON SUNDAY IN THE WAKE OF THE COLD FRONT THAT IS EXPECTED TO
SLIDE SLOWLY SOUTHEAST ACROSS KENTUCKY DURING THE AFTERNOON.
MEANWHILE...STRONG UPPER TROUGH TO SWING THROUGH MONDAY BUT SHOULD
NOT BE AS STRONG AS THE OUTLIER 12Z NAM...SO LEANED MORE HEAVILY ON
A MIX OF THE OTHER MODELS. AT ANY RATE...BEST CHANCE OF
THUNDERSTORMS SHOULD BE DURING THE MORNING HOURS ON SUNDAY AND
DECREASING FROM NORTHWEST TO SOUTHEAST DURING THE AFTERNOON AND
FINALLY ENDING FROM NORTHWEST TO SOUTHEAST OVERNIGHT SUNDAY NIGHT.
THEN...HIGH PRESSURE WILL BUILD IN ON MONDAY AND TUESDAY ALLOWING
FOR DRY BUT COOL WEATHER WITH TEMPERATURES BELOW NORMAL WHICH WILL
BE QUITE A CHANGE FROM WHAT WE HAVE BEEN EXPERIENCING. MODELS
CONSISTENT IN KEEPING THE REMNANTS OF LEE TO OUR SOUTH AND EAST
UNTIL MIDWEEK.

FOR NOW...WILL GO WITH GFS MOS FOR TEMPERATURES WHICH IS NOT QUITE
AS COOL AS THE NAM.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...

GFS HAS COME INTO LINE WITH THE ECMWF IN REGARD TO TRACK OF TROPICAL
STORM LEE/S REMNANTS.  AT THIS TIME...MODELS ARE SHOWING THE PRECIP
JUST SKIRTING THE SOUTHERN AND EASTERN PORTIONS OF CENTRAL INDIANA
AT THE BEGINNING OF THE EXTENDED PERIOD.  HOWEVER...IT APPEARS THAT
THE AFOREMENTIONED LOW RETROGRADES BACK TO THE WEST ON FRIDAY AND
SATURDAY...POSSIBLE BRINGING PRECIP FURTHER INTO CENTRAL INDIANA.
CURRENT THINKING IS THAT IT/S PATH IS GOING TO DEPEND HEAVILY ON
WHAT HURRICANE KATIA DOES AS IT WORKS ITS WAY UP THE ATLANTIC. AS A
RESULT...CONTINUED TO BE CONSERVATIVE WITH POPS...ONLY GOING WITH
CHANCE POPS AT THE VERY HIGHEST FOR NOW ACROSS THE EASTERN PORTIONS
OF FORECAST AREA.  TEMPS THROUGH THE PERIOD WILL BE CLOSE TO NORMAL
WITH HIGHS IN THE 70S AND LOWS IN THE 50S...GENERALLY STUCK WITH
GUIDANCE.

&&

.AVIATION /DISCUSSION FOR THE 032100 TAF UPDATE/...

SCATTERED POP UP THUNDERSTORMS HAVE DEVELOPED ACROSS CENTRAL INDIANA
OVER THE LAST HOUR. HAVE ADDED CB AND VCTS TO ALL SITES THROUGH
SUNSET AS THESE ARE DIURNAL IN NATURE WITH A LITTLE HELP FROM A WEAK
CONVERGENT BOUNDARY ACROSS THE AREA. BASED ON THE GENERALLY SLOW
NORTH-NORTHEAST MOVEMENT OF THE CELLS HAVE ALSO ADDED TEMPO THUNDER
GROUPS TO ALL SITES BUT KIND...WHICH AT THIS TIME LOOKS LIKE IT MAY
AVOID THUNDER OVERHEAD WITH DEVELOPMENT JUST EAST AND ANOTHER AREA
FURTHER WEST.

A COLD FRONT IS PROGGED TO MOVE ACROSS THE REGION TONIGHT. TIMING
WILL HAVE TO BE ADJUSTED SOMEWHAT OVER THE NEXT FEW TAF
ISSUANCES...BUT CURRENT THINKING IS THAT SHOWERS AND THUNDERSTORMS
WITH THE FRONT WILL START MOVING INTO TAF SITES AFTER MIDNIGHT. FOR
NOW...WENT WITH VCSH DURING THE OVERNIGHT HOURS. CONDITIONS WILL
GRADUALLY DECREASE THROUGH THE COURSE OF THE NIGHT WITH MVFR LIKELY
BY DAYBREAK.
