AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
632 PM EDT SUN JUN 1 2014

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

&&

.SYNOPSIS...
ISSUED AT 127 PM EDT SUN JUN 1 2014

THE QUIET WEATHER OF THE PAST WILL CHANGE TO AN ACTIVE PATTERN FOR
MUCH OF THIS WORK WEEK...BRINGING THUNDERSTORM CHANCES AND HIGHER
HUMIDITY.

GULF MOISTURE ARRIVING AHEAD OF AN UPPER LEVEL WEATHER DISTURBANCE
WILL PROVIDE CHANCES FOR SHOWERS AND THUNDERSTORM LATE TONIGHT AND
ON MONDAY ACROSS CENTRAL INDIANA.

AFTER A QUICK BREAK ON TUESDAY...A WARM FRONT AND ANOTHER UPPER
LEVEL WEATHER DISTURBANCE WILL ARRIVE IN THE AREA ON
WEDNESDAY AND WEDNESDAY NIGHT...PROVIDING MORE CHANCES FOR
STORMS.

MORE UNSETTLED WEATHER IS EXPECTED TO PERSIST INTO THURSDAY AND
FRIDAY AS EVEN MORE UPPER LEVEL WEATHER DISTURBANCES PASS ACROSS
THE OHIO VALLEY AMID THE WARM AND HUMID AIR MASS IN PLACE.

&&

.NEAR TERM /TONIGHT/...

ISSUED AT 629 PM EDT SUN JUN 1 2014

UPPED POPS THIS EVENING BASED ON CURRENT RADAR TRENDS. STILL THINK
THAT CONVECTION WILL DIMINISH QUICKLY THIS EVENING WITH LOSS OF
HEATING AND WITH ATMOSPHERE BRING WORKED OVER. HAVE LIKELY POPS
BEFORE 00Z WHERE NEEDED BUT AFTER 00Z ONLY WENT CHANCE. WILL UPDATE
AS NECESSARY IF CONDITIONS WARRANT. LOOKS LIKE STORMS COULD PRODUCE
SMALL HAIL...BRIEF HEAVY RAIN...AND GUSTY WINDS.

PREVIOUS DISCUSSION FOLLOWS...
SURFACE ANALYSIS EARLY THIS AFTERNOON SHOWS HIGH PRESSURE IN PLACE
ACROSS THE MIDDLE ATLANTIC STATES. WARM AND MOIST SOUTHERLY FLOW
HAS TAKEN SHAPE ACROSS CENTRAL INDIANA AS DEW POINTS WERE CREEPING
INTO THE UPPER 50S AND LOWER 60S. WATER VAPOR IMAGERY SHOWS A
PLUME OF GULF TROPICAL MOISTURE STREAMING AROUND THE HIGH TO THE
EAST ACROSS THE GULF AND NORTH INTO THE OHIO VALLEY.

TWO TRIGGERING MECHANISMS EXPECTED TONIGHT. THE FIRST WILL BE THE
WANING DAYTIME HEATING. HRRR HAS CONTINUED TO HINT AT ISOLATED
LATE AFTERNOON AND EVENING CONVECTION DEVELOPMENT...PARTICULARLY
ACROSS THE WESTERN PARTS OF CENTRAL INDIANA. SUBSEQUENT RUNS HAVE
ALSO TRENDED DOWNWARD WITH THE OVERALL COVERAGE. GIVEN THE HIGH
CONVECTIVE TEMPS...NOT A LOT OF TIME WILL BE AVAILABLE FOR
CONVECTION THIS AFTERNOON. THUS WILL TREND CHCS TOWARD A SLIGHT OR
ISOLATED COVERAGE MAINLY ACROSS THE WESTERN PARTS OF THE FORECAST
AREA.

LATE TONIGHT THE GFS AND NAM BOTH DEPICT A SHORT WAVE PASSING
TOWARD CENTRAL INDIANA. PLENTY OF GOOD MOISTURE REMAINS IN PLACE.
TIME HEIGHT SECTIONS SHOW DEEPER MOISTURE ARRIVING AFTER 06Z...BUT
BEST LIFT DOES NOT ARRIVE UNTIL AFT 12Z...AND THAT IS MAINLY
ACROSS THE WESTERN PARTS OF THE FORECAST AREA. THUS WILL TRY AND
TREND POPS LOWER ACROSS THE EAST BUT STICK CLOSE TO THE HIGHER
POPS ACROSS THE WEST AS ARRIVAL OF THE DYNAMICS REMAINS QUESTIONABLE.

AS FOR TEMPS...GIVEN THE CLOUDS AND HIGH DEW POINTS ASSOCIATED WITH
THE MOIST SOUTHERLY FLOW...WILL TREND LOWS AT OR ABOVE PERSISTENCE.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY/...

ISSUED AT 127 PM EDT SUN JUN 1 2014

MODELS ARE IN GOOD AGREEMENT WITH THE OVERALL PATTERN AND WILL USE
A BLEND.

ACTIVE WEATHER PATTERN IS SETTING UP FOR THIS PERIOD. WE PICK UP
AT 12Z MONDAY WITH THE GFS AND NAM SUGGESTING A SHORT WAVE PUSHING
ACROSS THE STATE...BEST FORCING ACROSS THE NORTHERN PARTS OF THE
FORECAST AREA. TIME HEIGHTS HERE SHOW GOOD SATURATION AND THE BEST
LIFT OF THE NEXT 36 HOURS OR SO. PLENTIFUL MOISTURE WILL ALSO
REMAIN IN PLACE AS SOUTHERLY FLOW IS AVAILABLE AND DEW POINTS ARE
EXPECTED TO CLIMB INTO THE MIDDLE 60S. GIVEN THE TIMING ISSUES AS
STATED IN THE EARLIER PERIOD...WILL FLIP THE SCENARIO HERE AND
HAVE HIGHEST POPS IN THE EAST...AND STICK CLOSE TO GUIDANCE IN THE
WEST. GIVEN THE EXPECTED RAIN...BUT VERY WARM AIR MASS WILL BLEND
MAV AND MET HIGHS.

ON MONDAY NIGHT FORCING IS LOST AS THE SHORT WAVE DEPARTS AND
FORECAST SOUNDINGS SHOW DRYING WORKING INTO THE COLUMN AS THE
NIGHT PROGRESSES. THIS IS THE LEADING EDGE OF A POORLY ORGANIZED
AREA OF HIGH PRESSURE THAT LOOKS TO BUILD ACROSS INDIANA FROM THE
CENTRAL PLAINS. THIS SHOULD GIVE US A BREAK IN THE PRECIPITATION ON
MONDAY NIGHT THROUGH TUESDAY NIGHT. A SMALL BUT DECENT MID LEVEL
RIDGE LOOKS TO PUSH ACROSS THE STATE ON TUESDAY INTO TUESDAY
NIGHT...PROVIDING SUBSIDENCE. BY THIS TIME LOWER LEVEL FLOW HAS
CHANGED TO WEST OR NORTHWESTERLY CHANGING THE AMOUNT OF AVAILABLE
MOISTURE. THUS WILL TREND POPS LOWER ON MONDAY NIGHT THROUGH
TUESDAY NIGHT...BUT STICK CLOSE ON TEMPS AS LITTLE TO NO
TEMPERATURE ADVECTION IS PROVIDED.

THROUGH THIS ENTIRE PERIOD THE GFS AND NAM BOTH CONTINUE TO
SUGGEST A QUICK AND RELATIVELY ZONAL FLOW OVER INDIANA. THIS MEANS
THAT THE PREVIOUSLY MENTIONED WEAK RIDGE WILL NOT BE LONG LIVED
OVER CENTRAL INDIANA AND WILL QUICKLY DEPART ON WEDNESDAY.
NUMEROUS THINGS COMING INTO SHAPE FOR PRECIP ON WEDNESDAY. THE
FIRST BEING THE APPROACH OF A WARM FRONT FROM THE
SOUTHWEST...PROVIDING GOOD LOWER LEVEL CONVERGENCE. NEXT IS A
STRONG UPPER LEVEL WEATHER DISTURBANCE PUSHING TOWARD
CENTRAL INDIANA PROVIDING GOOD LIFT. FORECAST SOUNDINGS REVEAL A
CONDITIONALLY UNSTABLE COLUMN WITH CONVECTIVE TEMPS IN THE LOWER
80S. FINALLY...THE 310K GFS ISENTROPIC SURFACE SHOWS EXCELLENT
UPGLIDE WITH VERY MOIST SPECIFIC HUMIDITIES OVER 7 G/KG. THUS WILL
TREND POPS HIGHER ON WEDNESDAY...PARTICULARLY DURING THE AFTERNOON
HOURS WHEN HEATING AND FORCING APPEAR TO COME TOGETHER BEST.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...

ISSUED AT 152 PM EDT SUN JUN 1 2014

ENSEMBLES CONTINUE TO SUGGEST AN ACTIVE PATTERN FOR THIS TIME PERIOD
WITH SEVERAL DISTURBANCES MOVING THROUGH RELATIVELY WEAK AND LOW
AMPLITUDE FLOW. THE MOST STRONG AND LIKELY SYSTEM WILL BE ON IT/S
WAY OUT OF THE AREA AT THE BEGINNING OF THE PERIOD...WED NIGHT.
THERE IS STILL A SLIGHT RISK OF SEVERE WEATHER DURING THIS TIME WITH
DAMAGING WINDS...LARGE HAIL AND EVEN A FEW TORNADOES AS THE MAIN
THREATS.

ALLBLEND GUIDANCE APPEARS TO HANDLE THIS UNSETTLED PERIOD QUITE WELL
WITH ALMOST DAILY CHANCES FOR SHOWERS AND THUNDERSTORMS. TEMP RIGHT
AT CLIMO DURING THIS TIME AS WELL. HIGHS IN THE 70S AND LOWS IN THE
50/60S.

&&

.AVIATION /DISCUSSION FOR THE 020000Z TAFS/...
ISSUED AT 632 PM EDT SUN JUN 1 2014

QUITE A BIT OF CONVECTION CURRENTLY ACROSS WESTERN AND SOUTHERN
INDIANA AT THIS TIME. APPEARS THERE IS A WEAK UPPER WAVE ENTERING
WESTERN INDIANA ASSOCIATED WITH THIS ACTIVITY. CONVECTION HAS BEEN
SLOWLY WEAKENING AND BECOMING MORE EMBEDDED WITH TIME...BUT
LIGHTNING ACTIVITY STILL RATHER HIGH. CONSIDERING THERE IS SOME
UPPER SUPPORT...THIS ACTIVITY MAY LINGER A LITTLE LONGER THAN
NORMALLY EXPECTED.

SHORT TERM MODELS PUSH THIS UPPER WAVE EAST OF THE TAF SITES BY
020200Z...SO THE CONVECTIVE THREAT SHOULD REMAIN HIGH UNTIL THEN.
BRIEF IFR VISIBILITY RESTRICTIONS AND GUSTY SHIFTING WINDS IN AND
NEAR THE HEAVIER CONVECTION.

OTHERWISE...SHOULD BE SOME LIGHT FOG DEVELOPING AFTER 020300Z
CONSIDERING THE RAINFALL AND HIGHER DEWPOINTS. APPEARS SURFACE WINDS
MAY STAY UP ENOUGH TONIGHT TO PREVENT WIDESPREAD IFR
VISIBILITIES...BUT IF THE WINDS DROP OFF MORE THAN EXPECTED...IFR
CONDITIONS ARE MORE LIKELY.

FINALLY...SHORT TERM MODELS SUGGEST CEILING 010-015 WILL DEVELOP
TOWARDS SUNRISE MONDAY.
