AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
730 AM EDT FRI APR 3 2009

.AVIATION DISCUSSION...FOR THE 12Z TAFS
MAIN PROBLEM FOR AVIATION WILL BE WINDS. TAFS WILL START OUT WITH
VERY STRONG LOW PRESSURE OVER WESTERN OHIO. THIS WILL CONTINUE TO
MOVE TO THE NORTHEAST. VERY TIGHT PRESSURE GRADIENT WAS CAUSING WIND
GUSTS AROUND 35 KTS. AS THE LOW MOVES AWAY FROM INDIANA THE GRADIENT
WILL WEAKEN DECREASING THE WINDS THIS AFTERNOON. MOISTURE WRAPPING
AROUND THE LOW WAS CAUSING MVFR CIGS. AS HIGH PRESSURE BUILDS INTO
INDIANA THIS AFTERNOON CONDITIONS WILL BECOME VFR. THE HIGH PRESSURE
WILL MOVE OVER INDIANA TONIGHT. THIS WILL GIVE CLEAR SKIES.

&&

.DISCUSSION...

FORECAST FOCUS WILL BE ON TEMPERATURES THE NEXT FEW DAYS INCLUDING
A POSSIBLE SIGNIFICANT COLD SNAP.

THE EARLY MORNING SURFACE MAP AT 3 AM SHOWS A STRONG LOW PRESSURE
CENTERED OVER SOUTHEAST INDIANA NEAR KSER. FROM THIS LOW A COLD
FRONT TRAILED SOUTH THROUGH ALABAMA AND INTO THE GULF. HIGH
PRESSURE WAS CONTROLLING THE MID SECTION OF THE COUNTRY. ALOFT AT
H5 THE PATTERN WAS SOMEWHAT CHAOTIC AND BUSY. THERE WAS TROUGHING
ACROSS THE WEST COAST...RIDGING ALONG THE HIGH PLAINS...TROUGHING
IN THE MIDWEST...AND RIDGING OFF THE EAST COAST.

THE MODELS ARE INITIALIZED WELL AND SHOW JUST SOME MINOR
DIFFERENCES FOR THE NEXT THREE DAYS. A BLEND WAS USED BUT IN THE
LATER PERIODS IT IS CONSIDERED THAT THE MEX IS BEING INFLUENCED BY
CLIMATOLOGY IN WHAT COULD BE AN ANOMALOUSLY COLD EARLY APRIL
PATTERN BY EARLY NEXT WEEK.

TODAY THE LOW WILL CONTINUE TO EXIT QUICKLY NORTHEAST. A VORT MAX
OVER THE UPPER MIDWEST WILL SWING SOUTH THROUGH INDIANA AND KEEP
ENOUGH LIFT FOR A FEW SHOWERS THROUGH 18Z. SURFACE WINDS ARE
EXPECTED TO INCREASE TO SUSTAINED 15-20KTS FOR MOST OF THE DAY
WITH GUSTS UP TO 30KTS POSSIBLE. DID NOT GO WITH A WIND ADVISORY.
BUFKIT SHOWS A POORLY MIXED ATMOSPHERE EARLY DUE TO CLOUDS AND
THIS IS WHEN THE STRONGEST WINDS ALOFT ARE PRESENT. BY THE TIME
THE ATMOSPHERE BECOMES BETTER MIXED...THE STRONGER WINDS ALOFT
WILL BE GONE. SO WILL GO WITH SUB-ADVISORY CRITERIA WIND GUSTS UP
TO 30KTS. TEMPS TODAY WILL BE COOLER DUE TO COLD ADVECTION EARLY.
THERE SHOULD BE A REBOUND IN THE LATER AFTERNOON WITH CLEARING
SKIES. WINDS WILL DROP OFF QUICKLY BY 00Z AS THE SFC GRADIENT
RELAXES CONSIDERABLY WITH HIGH PRESSURE BUILDING IN.

TONIGHT AND SATURDAY WILL BE QUIET AND AFTER A CHILLY NIGHT
TONIGHT WILL EXPECT REBOUNDING TEMPS SATURDAY. YET ANOTHER LEE
TROUGH WILL UNDERGO SIGNIFICANT CYCLOGENESIS ON SATURDAY AND
DEEPEN AS A PACIFIC TROUGH EJECTS OUT OF THE ROCKIES. THIS WILL
INCREASE WARM ADVECTION FLOW ACROSS INDIANA LATE ON SATURDAY WITH
H8 TEMPS TO NEAR +6C. THIS WILL SUPPORT HIGHS IN THE LOW 60S. A
SURFACE WARM FRONT WILL ACCOMPANY THIS LOW AND IT IS LIKELY TO
PUSH TO CENTRAL PORTIONS OF THE STATE BY 12Z SUNDAY. THIS WILL
SET UP A TEMPERATURE GRADIENT ACROSS NORTH TO SOUTH AND THE
MILDEST AIR SHOULD REMAIN CONFINED FROM INDY TO THE SOUTH.

ON SUNDAY HAVE INCREASED POPS AS THE LOW BARRELS STRAIGHT EAST
ACROSS THE AREA. ISENTROPIC SURFACES AT 300K SHOW STRONG UPGLIDE
BY 18Z SUNDAY AS THE SFC WARM FRONT LIFTS NORTH. THIS WARM FRONT
WILL ALSO SET UP A PROBLEMATIC TEMPERATURE FORECAST WITH MID 60S
POSSIBLE IN THE SOUTH AND LOW 50S IN THE NORTH. GOOD STRONG
ISENTROPIC LIFTING IS STILL PRESENT ON THE 300K SFC BY 00Z MON.
HAVE INCREASED POPS THE MOST ACROSS THE NORTH TO CATEGORICAL GIVEN
THE WARM FRONT POSITION OVER CENTRAL INDIANA AND THE ASSOCIATED
STRONG ISENTROPIC UPGLIDE.

THIS LOW WILL MOVE EAST BY MONDAY MORNING HOWEVER THERE WILL BE A
SIGNIFICANT POLAR AIR INTRUSION BEHIND IT. A SHARPLY AMPLIFIED
TROUGH WILL BE STRENGTHENED BY THE UPPER LOW PASSING THROUGH THE
AREA AS WELL AS A STRONG SHORTWAVE OVER THE EASTERN DAKOTAS. H8
TEMPS LOOK DOWNRIGHT FRIGID WITH A LARGE POOL OF -12C AIR DEPICTED
TO OUR WEST. THIS WILL SWING INTO INDIANA AS THE SURFACE PATTERN
IS A STRONG HIGH PRESSURE OVER THE HIGH PLAINS AND LOW PRESSURE
OVER THE EASTERN GREAT LAKES...CREATING A STRONG AND DEEP COLD
ADVECTION PATTERN ACROSS THE PLAINS AND MIDWEST. HIGHS ON MONDAY WILL
STRUGGLE TO HIT 40 WITH H8 STAYING NEAR -8C ALL DAY AND EXPECTED
EXTENSIVE CLOUD COVER. WILL GO WITH CHANCE POPS FOR SNOW SHOWERS
ON MONDAY AS IT WILL BE COLD ENOUGH TO SUPPORT SNOW.

OVERNIGHT MONDAY WILL HAVE A POTENTIAL FOR A VERY COLD NIGHT. WILL
HAVE TO MONITOR CLOSELY. DESPITE EXPECTED CLOUDINESS AND
FLURRIES...THE H8 TEMPS OF -12C WILL SUPPORT LOWS IN THE LOW TO MID
20S ARE POSSIBLE IN AN ADVECTION FREEZE. THE 1000-500MB
THICKNESSES SUGGEST THE CORE OF COLD AIR WILL MOVE DIRECTLY OVER
CENTRAL INDIANA MONDAY NIGHT. IT IS INTERESTING THAT THIS FOLLOWS
UP AFTER A VERY MILD MARCH...JUST AS THE APRIL FREEZE OF 2007
FOLLOWED A VERY MILD MARCH THAT YEAR. ALTHOUGH THE TEMPERATURES
THAT YEAR IN MARCH WERE MUCH WARMER. WILL HAVE TO MONITOR THIS
SITUATION FOR POSSIBLE FREEZE HEADLINES IN LATER PACKAGES.
