AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
630 PM EST SAT MAR 11 2006

.AVIATION...
THIS EVENING A COLD FRONT WILL BE APPROACHING FROM THE WEST...AND
MOVING INTO THE NORTHWEST CORNER OF THE AREA BEFORE 12Z. ENOUGH
MOISTURE AT LOW LEVELS BEING ADVECTED OVER THE AREA TO PROVIDE MVFR
CIGS...THEN IFR WX EXPECTED WITH SHRA AND TSRA ALONG AND AHEAD OF
FRONT. CLEARING EXPECTED IMMEDIATELY BEHIND THE FRONT AS DRIER AIR
MOVES IN. AS FRONT APPROACHES WINDS SHOULD BACK TO THE WEST
OVERNIGHT AND THEN SWING NORTHWEST AFTER FRONTAL PASSAGE...SUNDAY
MORNING.

&&

.SHORT TERM...
TEMPERATURES AND CLOUD COVERAGE ARE ABOUT THE BIGGEST QUESTIONS FOR
TONIGHT AND TOMORROW...WITH WHEN ITS GOING TO RAIN AND HOW MUCH
THUNDER THE NEXT QUESTIONS. TEMPERATURES HAVE WARMED UP MORE THAN
EXPECTED TODAY AND SKIES HAVE BECOME MOSTLY SUNNY. SO WITH THE
ADVANCING COLD FRONT FROM THE WEST...HOW WILL THE SKIES CLOUD UP AND
CONSEQUENTLY HOW FAR WILL TEMPERATURES BE ALLOWED TO DROP. DID NOT
ALTER AREA MIN TEMPS TONIGHT THAT MUCH EXPECT FOR IN OUR OHIO
COUNTIES. TEMPERATURES THERE HAVE NOT WARMED UP THAT MUCH MORE THAN
FORECASTED LOWS...AND WITH SOME PARTLY CLOUDY SKIES TO BEGIN THIS
EVENING...TEMPERATURES WILL FALL MORE THAN ZERO TO 3 DEGREES. FOR
THE FIRST PART OF THIS EVENING THE CLOUD COVERAGE IS A LITTLE BIT IN
QUESTION BUT SKIES SHOULD BE MOSTLY CLOUDY TO CLOUDY SHORTLY BEFORE
OR AROUND MIDNIGHT...ONCE THE COLD FRONT GETS CLOSER. WAS NOT TOO
IMPRESSED WITH THE GFS...WITH IT SEEMINGLY OVERDOING A LOT OF THINGS
ONE OF WHICH WAS THE PRECIP AND CLOUDS FOR TODAY. THE NAM LOOKS TO
HAVE A BETTER HANDLE ON THINGS AND THEREFORE CONSIDERED IT MORE OVER
OTHER MODELS. THE NAM HAD KEPT THE RAIN DOWN TO OUR SOUTH FOR
TODAY...PRETTY MUCH WHERE THE RAIN STAYED AT. AROUND MIDNIGHT THE
FRONT WILL BE INTO NORTHERN ILLINOIS. A LOW LEVEL JET WILL SET UP
AHEAD OF THE ADVANCING COLD FRONT...UP TO 55 KNOTS SOUTHWEST OF THE
CWA POINTED RIGHT AT US...AND THEN MAINLY AFTER MIDNIGHT THE JET
WILL MOVE OVER THE CWA AT 40 TO 45 KNOTS. THIS WILL USHER MOISTURE
INTO THE AREA. MODEL SOUNDINGS HAVE DEEPER MOISTURE LATER TONIGHT
AND BIG ENOUGH CLOUD DEPTH TO CONTAIN ICE IN THE UPPER PORTION. THIS
WILL ALLOW FOR GOOD LIGHTENING/THUNDER DYNAMICS TO OCCUR. THIS ALONG
WITH LIFT TONIGHT...MAINLY ASSOCIATED WITH THE FRONT...NAM SHOWING
DECENT OMEGA AND UPPER LEVEL DIVERGENCE AND LOWER LEVEL CONVERGENCE
MOVING THROUGH TONIGHT...WILL CAUSE SHOWERS AND THUNDERSTORMS FOR
THE CWA. THE LAST TWO RUNS OF THE NAM HAVE SLOWED THINGS DOWN A
LITTLE BIT...SO ALSO SLOWED DOWN THE BEST PRECIP CHANCES TO CLOSER
TO MIDNIGHT AND EXTENDED THE PRECIP CHANCES A LITTLE INTO TOMORROW
MORNING. MOST MODELS DO AGREE THAT THE COLD FRONT WILL MOVE THROUGH
THE CWA TONIGHT AND THEN STALL OUT IN OUR EASTERN COUNTIES AND
EXTEND SOUTHWESTWARD JUST SOUTH OF OUR SOUTHERN COUNTIES AROUND 12Z.
STILL EXPECTING MOST OF SUNDAY TO BE DRY AS SOUNDINGS ARE SHOWING
MOST OF THE MOISTURE IN THE ATMOSPHERE TO MOVE ON TO THE EAST AND
SKIES BECOMING PARTLY CLOUDY. WITH SUNSHINE TOMORROW AND A GOOD
NORTHWEST WIND...WILL MAKE TOMORROWS HIGHS A LITTLE TRICKY BUT MADE
NO CHANGES TO TOMORROWS HIGHS WITH TEMPS STILL EXPECTED TO BE AROUND
FORECASTED HIGHS.
