AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
1215 AM EST WED JAN 2 2008

.AVIATION...DISCUSSION FOR 06Z TAFS

SNOW SHOWERS LOOK TO CONTINUE TO DECREASE ACROSS THE TAF SITES IN
THE EARLY PART OF THE TAF PD. WILL HAVE TO WATCH LAF FOR POSSIBLE
LAKE BANDS...BUT HAVE GONE OPTIMISTIC AND ENDED SNOW THERE BY 09Z.
VSBYS MAY STILL GO TO IFR AT LAF EARLY FOR BRIEF PERIODS...BUT
EXPECT MVFR OR BETTER VSBYS ELSEWHERE EARLY BEFORE BECOMING VFR BY
09Z.

LOW LEVEL MOISTURE WILL REMAIN ACROSS THE TAF SITES THROUGH THE
PERIOD...SO CONTINUED MVFR CIGS THROUGH MUCH OF THE DAY...WITH
IMPROVEMENT EXPECTED BY EVENING.

&&

.PREV DISCUSSION...

FORECAST PROBLEM WILL BE ONGOING SNOW SHOWERS THIS EVENING AND
TONIGHT. THEN JUST A TEMPERATURE GAME WITH LOTS OF UPS AND DOWNS
OVER THE NEXT SEVEN DAYS.

THE AFTERNOON SURFACE MAP SHOWED A COLD FRONT PUSHING THROUGH
SOUTH CENTRAL KENTUCKY...TRAILING FROM A LOW OVER THE LAKES. A
1056MB HIGH WAS OVER THE ROCKIES. IN BETWEEN THE TWO REMAINED A
STIFF NORTHERLY GRADIENT ACROSS THE PLAINS AND MIDWEST. ALOFT AT
H5 THE PATTERN WAS A TROUGH OVER THE EASTERN HALF OF THE COUNTRY
WITH A RIDGE OUT WEST. A FAIRLY VIGOROUS SHORTWAVE WAS SEEN OVER
THE UPPER MISSISSIPPI VALLEY...DIVING QUICKLY INTO THE OHIO
VALLEY.

THE MODELS REMAINED VERY SIMILAR IN THEIR HANDLING OF THE PATTERN
AND MOS GUIDANCE WAS VERY CLOSE SO IT WAS BLENDED.

FOR THIS EVENING AND TONIGHT...THE APPROACHING VORT MAX WILL
CONTINUE TO ENHANCE CONVECTIVE SNOW SHOWERS ACROSS THE AREA...AND
AFTER THE VORT MAX PASSES THERE SHOULD BE LAKE EFFECT SNOWS OVER
NORTHERN INDIANA AND INTO THE FAR NORTHEAST ZONES. GIVEN THE
STRONG VORT AND INSTABILITY FROM VERY COLD AIR ALOFT AS WELL AS
LAKE ENHANCEMENT...WILL GO WITH LIKELY POPS OR DEFINITE ACROSS THE
NORTHEASTERN HALF OF THE AREA UNTIL 06Z. LOWER POPS AFTER 06Z AS
THE VORT QUICKLY EXITS SOUTHWARD AND DAYTIME HEATING IS LONG GONE.
ACCUMULATIONS WILL BE RATHER LIGHT. TODAY THE SNOW LIQUID RATIO
HAS BEEN OFF THE CHARTS. ALL SITES HAVE REPORTED JUST A TRACE OF
LIQUID...BUT ACCUMULATIONS HAVE RANGED FROM A DUSTING TO A HALF
INCH FROM THIS TRACE OF LIQUID. SO FOR TONIGHT EXPECTING LESS THAN
AN INCH IN MOST PLACES...EXCEPT A LITTLE MORE THAN ONE INCH IN THE
EXTREME NORTHEAST WHERE LAKE ENHANCEMENT WILL KEEP THINGS GOING
LONGER. FOR LOWS TONIGHT...THINK THAT MOSTLY CLOUDY SKIES AND
STRONG WINDS WILL KEEP TEMPERATURES UP A BIT. SO LOWER TEENS
LOOKED REASONABLE FROM THE MOS. AS A RESULT OF THE COLD AND
WINDS...DO EXPECT WIND CHILLS OF -5 TO PERHAPS -10 TONIGHT. BUT
THIS DOES NOT MEET CRITERIA FOR ADVISORY SO AM JUST PLANNING TO
MENTION IT IN THE HWO TONIGHT.

FOR WEDNESDAY...SNOW WILL BE CONFINED TO JUST THE NORTHEAST AREAS
AND MOSTLY EARLY. ONLY VERY LIGHT ACCUMULATIONS EXPECTED THERE.
ELSEWHERE JUST COLD...BREEZY...AND GRADUAL CLEARING FROM WEST TO
EAST. A 1046MB HIGH WILL BE MOVING EAST INTO THE MISSISSIPPI
VALLEY AT THIS TIME AND SHOULD PROVIDE THE PUSH FOR CLEARING LATE
IN THE DAY WEST. HOWEVER A CYCLONIC FLOW ALOFT WILL REMAIN OVER
THE EASTERN HALF AND SO WILL NOT BE TOO AGGRESSIVE WITH CLEARING.
H8 TEMPS REMAIN NEAR -14C. THIS WILL BRING HIGHS IN THE UPPER 10S
NORTH AND LOW 20S SOUTH.

OVERNIGHT WEDNESDAY A VERY COLD NIGHT COULD BE ON TAP. A NEAR
1045MB HIGH WILL MOVE INTO THE OHIO VALLEY OVERNIGHT. THIS WILL
CLEAR SKIES AND BRING WINDS TO NEAR CALM LATE. THE WILD CARD IS
HOW MUCH SNOW WILL BE ON THE GROUND. CLOUDS AND WIND WILL HOLD
TEMPS UP EARLY IN THE NORTHEAST...BUT LONGER PERIOD OF RADIATION
IS EXPECTED CENTRAL AND SOUTH. WILL HAVE TO KEEP AN EYE ON HOW
MUCH SNOW FALLS...BUT FOR NOW JUST KNOCKED OFF A FEW DEGREES FROM
MOS IN THE LOW AND MID SINGLE NUMBERS ABOVE ZERO.

BY THURSDAY THE SURFACE HIGH WILL SHIFT SLIGHTLY EAST AND ALLOW
FOR WARM ADVECTION TO DEVELOP IN THE WESTERN AREAS. WILL NOT BE
OVERLY AGGRESSIVE MOVING THE HEAVY COLD AIR OUT...AS THE MID LEVEL
RIDGING IS STILL TO OUR WEST AND THUS NOT CONDUCIVE TO FAST
WARMING AT THE SURFACE. THE MOS TEMPS IN THE MID TO UPPER 20S AND
LOW 30S SOUTH LOOKED REASONABLE FOR NOW.

OVERNIGHT THURSDAY SHOULD BE ONE MORE COLD NIGHT. WILL HAVE TO
WATCH THIS NIGHT AS WELL FOR COLDER THAN FCST IF IT RADIATES VERY
STRONGLY EARLY BEFORE WARM ADVECTION KICKS IN. LOWS IN THE 10S TO
LOW 20S AS THE RIDGING ALOFT MOVES TO THE EAST AND DEVELOPS A
STRONG WARM ADVECTION FLOW AS THE OVERALL PATTERN BECOMES ZONAL.

FOR THE EXTENDED THE GENERAL TREND WILL CONTINUE TO BE A WARMING
ONE. BY LATE FRIDAY H8 TEMPS OF +4C ARE EXPECTED TO BRING HIGHS
ABOVE FREEZING AGAIN. THE SURFACE HIGH WILL SETTLE OFF THE
SOUTHEAST COAST AND START TO DEVELOP A VERY EFFICIENT WARM
ADVECTION REGIMES FROM THE SURFACE ON UP THROUGH H7. SINCE THE
GULF HAS BEEN SCOURED OUT...IT SHOULD TAKE A FEW DAYS TO BRING
HIGHER DEWPOINTS BACK IN...BUT BY SATURDAY AND SUNDAY A POWERFUL
PACIFIC STORM WILL HELP TO TURN THE PATTERN INTO ONE OF WEST COAST
TROUGHING AND RIDGING EVERYWHERE ELSE. HAVE JUST BROAD BRUSHED POPS
IN THE EXTENDED SINCE THERE LOOKS TO BE SOME LIGHT PRECIP AROUND
NEARLY EVERY DAY WITH SEVERAL EMBEDDED VORT MAXES IN THE FAST ZONAL
FLOW.
