AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
153 PM EDT SUN MAY 12 2013

.UPDATE...
THE LONG TERM SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...
ISSUED AT 355 AM EDT SUN MAY 12 2013

A STRONG UPPER TROUGH OVER THE GREAT LAKES AND AN UPPER RIDGE OVER
THE ROCKIES WILL PROGRESS TO THE EAST NEXT FEW DAYS. BY THE EXTENDED
PERIOD THE UPPER FLOW WILL BECOME MORE ZONAL WITH SEVERAL UPPER
DISTURBANCES MOVING ACROSS OUR REGION.  A COLD FRONT WILL MOVE INTO
AN STALL ACROSS OUR REGION BY THURSDAY.

&&

.NEAR TERM /TODAY/...
ISSUED AT 355 AM EDT SUN MAY 12 2013

A STRONG UPPER TROUGH OVER THE GREAT LAKES WILL ALLOW UNSEASONABLY
COOL AIR TO SPILL ACROSS OUR REGION TODAY. THERE WILL BE STRONG COLD
ADVECTION AND 850 MB TEMPERATURES WILL DROP TO ABOUT -3 DEGREES
CELSIUS ACROSS OUR NORTHEAST LATER TODAY.  SATELLITE SHOWS CLEAR
SKIES CURRENTLY ACROSS OUR REGION. HOWEVER MODEL SOUNDINGS AND CU
RULE INDICATE SCATTERED CU ACROSS NORTH AND NORTHEAST SECTIONS THIS
AFTERNOON...WHILE LITTLE OR NO CLOUDS OCCUR ACROSS OUR SOUTHWEST.

NORTHWEST WINDS WILL BE AROUND 15 KNOTS LATER TODAY WITH GUSTS OF 20
TO 25 KNOTS.  A MOS BLEND ON TEMPERATURES SEEM REASONABLE MOST
AREAS.

&&

.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...
ISSUED AT 355 AM EDT SUN MAY 12 2013

MAIN FOCUS WILL BE ON TEMPERATURES THROUGH THE PERIOD AND
POSSIBILITY OF FROST AND WHETHER TO ISSUE ANY FROST HEADLINES AT
THIS TIME.

HIGH PRESSURE OVER THE PLAINS WILL BUILD INTO THE OHIO VALLEY BY
MONDAY MORNING. WINDS WILL BECOME LIGHT AND CLEAR SKIES WILL ALLOW
FOR STRONG RADIATIONAL COOLING LATE TONIGHT. EXPECT LOW TEMPERATURES
IN THE MID 30S NORTH AND EAST AND MID TO UPPER 30S ELSEWHERE. COLDER
AREAS MAY SEE LIGHT FROST.  BUT LOW TEMPERATURES SHOULD BE ABOVE
FREEZING ALL AREAS.  THIS SHOULD BE A MARGINAL FROST SITUATION AND
WILL GO WITH A SPECIAL WEATHER STATEMENT AT THIS TIME. FOR NOW...I
DECIDED NOT TO LOCK IN THE NEXT SHIFT WITH MARGINAL HEADLINES.

THE HIGH PRESSURE AREA WILL MOVE ON TO THE EAST AND SOME WARM
ADVECTION WILL START LATE MONDAY AND INCREASE BY TUESDAY. MODELS
HAVE TRENDED A LITTLE WARMER MONDAY AND THIS SEEMS REASONABLE AS
THERE WILL BE FULL SUNSHINE UNTIL VERY LATE MONDAY.

STRONG WARM ADVECTION WILL OCCUR MONDAY NIGHT AND TUESDAY. MODELS
INDICATE STRONG ISENTROPIC LIFT ESPECIALLY MONDAY NIGHT.  MODEL
SOUNDINGS INDICATE LOTS OF MID CLOUDS ARE POSSIBLE.  WITH A DRY
AIRMASS AT LOW LEVELS WILL NOT MENTION ANY SPRINKLES. HOWEVER I
WOULD NOT BE SURPRISED OF SOME VIRGA.

MUCH WARMER TEMPERATURES WILL BE THE RULE TUESDAY AND TUESDAY
NIGHT.  MODEL SOUNDINGS INDICATE LESS MID CLOUDS TUESDAY AND TUESDAY
NIGHT AS STRONGEST ISENTROPIC LIFT MOVES ON TO THE EAST. IN MOST
CASES MADE ONLY MINOR CHANGES TO MOS BLEND ON TEMPERATURES.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY NIGHT/...

ISSUED AT 152 PM EDT SUN MAY 12 2013

A VERY ACTIVE AND UNSETTLED PERIOD CHARACTERIZES THE LONG TERM AS A
SERIES OF UPPER DISTURBANCES WILL MOVE THROUGH THE AREA WHILE A
FRONT ARRIVES AND STALLS OUT. THIS FEATURE WILL BRING CHANCES FOR
SHOWERS AND THUNDERSTORMS FOR EACH DAY DURING THE PERIOD. ALLBLEND
SEEMS TO CAPTURE THIS ACTIVE PERIOD VERY WELL...SO OVERALL DID NOT
DEVIATE TOO FAR FROM THIS GUIDANCE. TEMPERATURES LOOK WARMER THAN
NORMAL UPPER 70S TO AROUND 80.

&&

.AVIATION /DISCUSSION FOR 121800Z TAF ISSUANCE/...

ISSUED AT 1224 PM EDT SUN MAY 12 2013

VFR THROUGH THE PERIOD. CU WILL CONTINUE TO DEVELOP AROUND 5K FT
AND WILL GUSTS IN THE 20 TO 25 KT RANGE...THEN ABATE AROUND 00Z.
CLEAR SKIES TONIGHT AND LIGHT WINDS. WINDS PICK BACK UP BUT REMAIN
LIGHT AROUND 15Z MONDAY.

&&

.IND WATCHES/WARNINGS/ADVISORIES...
NONE.
