AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
707 PM EST SUN DEC 28 2008

.AVIATION...DISCUSSION FOR 0Z TAFS.
HIGH PRESSURE WAS CENTERED TO THE S OF THE SITES. ONLY CLOUD COVER
IS SOME CIRRUS MOVING THROUGH. AIR TOO DRY FOR FOG TONIGHT. AS LOW
PRESSURE SYSTEM MOVES THRU THE GREAT LAKES TOMORROW PRES GRADIENT
TIGHTENS UP A BIT AND SNDINGS INDICATE WIND GUSTS IN THE AFTERNOON
TO 20-25KTS.

&&

.PREV DISCUSSION...HIGH PRESSURE WAS OVER ARKANSAS THIS AFTERNOON.
WIND HAS DECREASED SOME FROM EARLIER IN THE MORNING AS A WEAKER
PRESSURE GRADIENT MOVES IN WITH THE HIGH.

FORECAST FOCUS WILL BE ON TEMPS IN THE SHORT TERM.

SINCE THERE ARE ONLY MINOR DIFFERENCES WITH THE MODELS...UNLESS
OTHERWISE NOTED...WILL USE A BLEND.

TONIGHT WILL BE CLEAR AND ABOVE NORMAL OVERNIGHT.  WIND WILL BE FROM
THE SOUTH AT 5 TO 10 MPH WHICH WILL KEEP A LID ON RADIATIONAL
COOLING SO TEMPS ARENT EXPECTED TO DROP BELOW GUIDANCE TONIGHT.
HAVE DONE WITH A MOS BLEND FOR LOWS TONIGHT SINCE THERE IS LITTLE
DIFFERENCE BETWEEN THEM.

THE AFOREMENTIONED SURFACE HIGH PRESSURE DRIFTS EAST THROUGH MONDAY
ALLOWING WARMER SOUTH WINDS TO PREVAIL.  SOME WAA AT H85 OUT AHEAD
OF A SURFACE LOW OVER THE GREAT LAKES WILL HELP KEEP TEMPS ABOVE
NORMAL FOR MONDAY.

BY TUESDAY NIGHT A COLD FRONT PASSES THROUGH CENTRAL INDIANA
BRINGING A RETURN TO TEMPERATURES THAT ARE CLOSER TO NORMAL.  WITH
LITTLE MOISTURE AVAILABLE THE FRONT WILL PASS WITH NO PRECIPITATION
AND MAYBE JUST A FEW CLOUDS.  THE GFS TRIES TO BRING IN SOME QPF
WITH THIS FRONT BUT MOISTURE PROFILES/BUFKIT/OTHER MODELS DO NOT
SUPPORT THIS AND WILL LEAVE A DRY FORECAST.

HIGH PRESSURE WILL BE IN CONTROL OF THE WEATHER ON WEDNESDAY AND
THURSDAY SO DRY WEATHER CAN BE EXPECTED.

THE NEXT CHANCE FOR PRECIPITATION IS ON THURSDAY NIGHT INTO FRIDAY.
THE GFS/ECMWF HAVE BEEN SHOWING THIS SYSTEM FOR SEVERAL DAYS NOW AND
BOTH HAVE ALSO CONSISTENTLY BEEN COLD ENOUGH FOR ALL SNOW.  THIS IS
STILL DAY 5/6 TIME FRAME SO THINGS COULD CHANGE HOWEVER THERE HAS
BEEN VERY DECENT RUN TO RUN CONSISTENCY WITH THIS SYSTEM.
