AREA FORECAST DISCUSSION

320 PM EDT SUN APR 13 2008

.DISCUSSION...

SAT LOOP SHOWS OVC SKIES WITH UPR TROF STILL OVR THE FA. THIS WAS
CAUSING SCT LIGHT SHOWERS ACRS CENTRAL INDIANA AS SHOWN ON RADAR.
TEMPS WERE IN THE LOW 40S WITH DEWPTS IN THE MID 30S AND WINDS OUT
OF THE N AROUND 10KTS.

MODELS IN GOOD AGREEMENT IN SHORT TERM SO WL USE A BLEND. FOR
TEMPS A MAV/MET BLEND WAS USED.

TONIGHT...CLOUDS WL BE SLOW TO MOVE OUT OF THE AREA AS UPR LOW CONTS
TO SLOWLY DRIFT EAST. INCLUDED CHC POPS EARLY IN THE SE AS SCT SHRA
MAY BE ONGOING AND COULD SEE A LITTLE SNOW MIX IN. WITH CAA SHUD SEE
TEMPS FALL TO BLO FREEZING ACRS THE AREA SO WL ISSUE A FREEZE
WARNING.

MONDAY...UPR RDG STARTS TO BLD INTO THE AREA FROM THE W AND LEFTOVER
CLDS SHUD MV OUT FROM W TO E. WL SEE A LITTLE WAA BUT H8 TEMPS DON/T
INCREASE A LOT AND THUS HAVE HIGHS IN THE UPR 40S TO LOW 50S.

MON NT...WHILE H8 TEMPS ARE INCREASING TO AROUND -2C OR SO...SFC
HIGH WL BE ARRIVING AND CLR SKIES EXPECTED WITH LITTLE WIND SO
RADIATIONAL COOLING CONDS WL BE IDEAL. LOWS SIMILAR TO THOSE TONIGHT
ARE EXPECTED SO WL ISSUE A FREEZE WATCH FOR THIS TIME PD.

TUE...WAA REALLY KICKS IN ON STRONG SWLY WINDS AND WITH CLR SKIES
FROM HI PRES SHUD SEE TEMPS RISE INTO THE UPR 50S TO LOW 60S.

TUE NT...AGAIN NO CLD CVR EXPECTED UNDER THE HIGH BUT WITH WAA TEMPS
SHUD STAY IN THE MID TO UPR 30S.

EXTENDED...WHILE OP MODELS SHOW DECENT AGREEMENT...THEY DIFFER FROM
ENSEMBLES AND TELECONNECTION PATRNS ACCORDING TO HPC. GIVEN THESE
DISCREPANCIES WL STICK WITH HPC GUIDANCE AND THEIR PLAN TO FAVOR THE
ENSEMBLES AND SMOOTH SIGNIFICANT DIFFERENCES FROM PREV FCST. AS FAR
AS OVRALL PATRN IS CONCERNED WL SEE A RDG BLD IN TO THE AREA FOR MID
WEEK AND TEMPS WL WARM INTO THE LOW 70S FOR WED. ANOTHER UPR TROF WL
BRING RAIN CHCS IN FOR THE WEEKEND BUT THE STRENGTH OF THIS NEXT
SYSTEM IS STILL VERY MUCH UP IN THE AIR.

.AVIATION...DISCUSSION FOR 18Z TAFS.

WEAK SFC TROF ASSOCIATED WITH THE BROAD UPPER LOW WAS STILL
LINGERING ACRS CENTRAL INDIANA EARLY THIS AFTERNOON...PROVIDING MVFR
CIGS ALONG WITH SOME ISOLATED IFR CIGS. RADAR SHOWS PCPN MAINLY
AHEAD OF THE TROF...ACRS SRN INDIANA AND IT WAS EXITING THE TAF
SITES QUICKLY.

TIME SECTIONS SHOW LINGERING LWR LVL MOISTURE ACRS THE AREA UNTIL
LATE TONIGHT. THIS SEEMS REASONABLE GIVEN THE WEAK CYCLONIC FLOW
ACRS THE AREA. WL KEEP THE MVFR CIGS IN PLACE. A BRIEF PD OF VFR
CIGS COULD OCCUR DUE TO DAYTIME HEATING/MIXING...BUT FOR NOW EXPECT
CIGS TO FALL BACK TO MVFR LEVELS WITH COOLING AFT SUNSET.

ANTICYCLONIC FLOW BUILD ACRS THE AREA AFT 06Z AND THIS IS WHEN WE WL
START THE CLEARING TREND. VFR AFT 09Z TO 11Z AT THE TAF SITES.
