AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
315 PM EDT FRI APR 10 2009

.MESOSCALE UPDATE 5...

QUITE A BIT OF CONVECTION NOW IN PROGRESS ACROSS THE COMMONWEALTH.
ELEVATED CONVECTION CONTINUES ACROSS THE BLUEGRASS REGION WITH HEAVY
RAINS AND MARGINAL SEVERE HAIL BEING THE PRIMARY WEATHER THREATS.
THIS AREA CONTINUES TO BE DOMINATED BY STRONG WARM AIR ADVECTION
PATTERN ALOFT COURTESY OF THE LOW-LEVEL JET WHICH IS ORIENTED FROM
CENTRAL TN NE INTO EAST-CENTRAL KY.  MAIN CONCERN IN THE BLUEGRASS
WILL BE HEAVY RAIN AND HYDRO ISSUES AS EXCESSIVE RAINFALL IS
INCREASINGLY LIKELY.

FURTHER SOUTH...NORTHERN EDGE OF CONVECTIVE LINE CONTINUE TO MOVE
ACROSS OUR SOUTHEAST.  INSTABILITY HAS BEEN QUITE LIMITED DUE TO
EXCESSIVE CLOUDINESS AND PREVIOUS CONVECTION WHICH HAS WEAKENED
LOW-LEVEL LAPSE RATES.  NONETHELESS...COOLER AIR ALOFT AND STRONG
ASCENT DUE TO HEIGHT FALLS ASSOCIATED WITH VORT ROLLING THROUGH THE
REGION WILL LIKELY PROMOTE VIGOROUS CONVECTION FOR THE NEXT FEW
HOURS WHICH WILL AFFECT THE SOMERSET AND LONDON AREAS IN JKLS AREA.

FURTHER WEST...EVEN STRONGER DYNAMICAL FORCING ON THE SOUTHEAST EDGE
OF THE SFC LOW HAS LED TO A LONG LIVED HIGH PRECIPITATION (HP)
SUPERCELL THAT IS MOVING THROUGH BUTLER AND SOUTHERN OHIO COUNTIES.
ADDITIONAL CONVECTION IS DEVELOPING ALONG THE SOUTHERN FLANK DOWN
INTO LOGAN COUNTY. LOOK FOR THIS TO AFFECT THE BOWLING GREEN AREA
SHORTLY.  STILL CONTINUE THINK THAT THE HIGHEST RISK OF SEVERE WILL
STILL BE POSSIBLE ACROSS SOUTH-CENTRAL KY THROUGH 500 PM EDT.

ACROSS SOUTHERN INDIANA AND NORTH-CENTRAL KY...LOW-LEVEL STABLE
AIRMASS SEEMS TO BE WINNING OUT AS MUCH OF THE CONVECTION STILL
SEEMS TO BE SLIGHTLY ELEVATED.  NUMEROUS REPORTS OF HAIL HAVE BEEN
RECEIVED FROM THIS ACTIVITY WHICH ARCS FROM NEAR FLOYD COUNTY IN
EAST WARD OVER INTO THE BLUEGRASS REGION.  THIS ACTIVITY WILL
CONTINUE NE AND POSE A HEAVY RAIN AND MARGINAL SEVERE THREAT FOR THE
NEXT SEVERAL HOURS.

.SHORT TERM (TONIGHT AND SATURDAY)...

DYNAMIC MID-LEVEL SYSTEM IS FCST BY THE MODELS TO MOVE EASTWARD
ACROSS THE AREA TONIGHT.  AS THIS SYSTEM MOVES EAST...ASSOCIATED
SHOWER AND THUNDERSTORM ACTIVITY WILL END FROM WEST TO EAST.  WILL
KEEP HIGHEST POPS IN THE CENTRAL AND EASTERN SECTIONS THIS EVENING
AND THEN GRADUALLY LET THINGS END.  FEEL THAT MOST OF THE CONVECTION
WILL BE EAST OF OUR SERVICE AREA BY 23-24Z TONIGHT WITH MOSTLY
SHOWERS LINGERING FOR A FEW HOURS AFTER THAT.  ABUNDANT LOW-LEVEL
MOISTURE WILL REMAIN ENTRENCHED ACROSS THE REGION OVERNIGHT WITH
SOME FOG/MIST POSSIBLE.  SKIES SHOULD START TO CLEAR SUFFICIENTLY BY
SAT MORNING.  OVERNIGHT LOWS WILL RANGE FROM THE UPPER 30S ACROSS
SOUTHERN INDIANA...TO THE LOWER 40S ACROSS CENTRAL KY INCLUDING THE
BLUEGRASS REGION.  UPPER 40S WILL BE POSSIBLE ACROSS THE FAR SOUTH.

MOSTLY SUNNY CONDITIONS ARE EXPECTED FOR SATURDAY AS HIGH PRESSURE
AND RISING HEIGHTS BUILD INTO THE REGION. WELL LIKELY SEE A
GRADIENT OF TEMPERATURE WITH MID TO UPPER 50S IN THE BLUEGRASS
REGION AND UPPER 50S TO THE LOWER 60S ACROSS THE NORTH-CENTRAL
SECTIONS AND SOUTHWEST SECTIONS...INCLUDING SOUTHERN INDIANA.

.LONG TERM (SATURDAY NIGHT THROUGH FRIDAY)...

NOT MANY CHANGES WERE MADE TO THE EXTENDED FCST FOR THIS TIME PERIOD
AS FOCUS HAS BEEN ON HAZARDOUS WEATHER THIS AFTERNOON.

SATURDAY NIGHT THROUGH EASTER NIGHT...

GENERALLY CLEAR SKIES ARE EXPECTED SATURDAY NIGHT AS SFC HIGH DRIFTS
OVER THE REGION.  CHILLY CONDITIONS CAN BE EXPECTED EASTER MORNING
WITH LOWS IN THE LOWER 30S.  MOSTLY SUNNY SKIES ARE EXPECTED FOR
EASTER WITH HIGHS IN THE LOWER TO MID 60S ACROSS SOUTHERN INDIANA
AND MID TO UPPER 60S ACROSS SOUTHERN KY.  CLOUDS WILL BE ON THE
INCREASE AHEAD OF THE NEXT SYSTEM BY SUNDAY NIGHT...SO WILL INCREASE
THE CLOUDS A BIT IN THE GRIDS...ESPECIALLY ACROSS THE WEST. 12Z
GUIDANCE IS A BIT MORE AGGRESSIVE WITH PRECIP MOVING IN A BIT
FASTER.  THUS HAVE INCREASED POPS SLIGHTLY HERE.  OVERALL...LITTLE
CHANGE TO THE ONGOING FCST AT THIS TIME PD. LOWS WILL RANGE FROM THE
LOWER 40S IN THE BLUEGRASS REGION TO THE MID AND UPPER 40S ACROSS
CENTRAL KY AND OUR SW SECTIONS.

MONDAY THROUGH THURSDAY...

NEXT WEATHER SYSTEM IS FCST TO MOVE THROUGH THE REGION ON
MONDAY...BRING YET ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS TO THE
REGION.  SOME OF THESE STORMS COULD BE STRONG TO SEVERE ONCE
AGAIN...SO THIS BEARS WATCHING.  GIVEN THE INCREASED AGREEMENT IN
THE ENSEMBLES...HAVE RAISED POPS FOR MONDAY AND MONDAY NIGHT AS THIS
SYSTEM SLOWLY ROLLS EASTWARD.  WILL KEEP POPS IN FOR TUESDAY AS
UPPER LOW SLOWLY TRANSLATES EASTWARD.  ABUNDANT LOW-LEVEL MOISTURE
SHOULD KEEP MOSTLY CLOUDY CONDITIONS ACROSS THE REGION.  BY WED SFC
AND UPPER LOW SHOULD MOVE EAST OF THE REGION WITH IMPROVING WEATHER
CONDITIONS.  AFTER A BRIEF REPRIEVE...NEXT WEATHER SYSTEM WITHIN THE
PROGRESSIVE UPPER FLOW LOOKS TO ARRIVE BY THU WITH ANOTHER CHANCE OF
SHOWERS AND STORMS.

TEMPS THROUGH THE PD WILL TAKE A SLIGHT COASTER RIDE AS THE SYSTEMS
PULL THROUGH THE REGION.  HIGHS IN MONDAY SHOULD RANGE FROM UPPER
50S IN THE BLUEGRASS TO THE MID AND UPPER 60S ACROSS CENTRAL AND SW
SECTIONS.  TEMPS TUESDAY WILL BE RATHER COOL DUE TO CLOUD COVER...SO
EXPECT READINGS IN THE MID TO UPPER 50S. A GRADUAL WARM UP SHOULD
COMMENCE BY WED/THU AS WE GET INTO RETURN FLOW WITH MID TO UPPER 60S
EXPECTED.  OVERNIGHT LOWS LOOK TO RANGE FROM THE UPPER 40S TO THE
LOWER 50S.

&&

.AVIATION (18Z TAFS)...

SFC WARM FRONT CONTINUES TO MOVE NORTHWARD THROUGH KY EARLY THIS
AFTERNOON.  NUMEROUS SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS
THE REGION DUE TO STRONG LIFT AND JET DYNAMICS.  SCATTERED SHOWERS
AND STORMS WILL LIKELY AFFECT THE KBWG AND KLEX TERMINALS THROUGH
THE AFTERNOON HOURS.  WITHIN THE NEXT FEW HOURS...KLEX SEEMS TO BE
MOST AT RISK OF SEEING STORMS AS THERE IS QUITE A BIT OF ACTIVITY TO
THE SOUTHWEST.  MORE ORGANIZED CONVECTIVE ACTIVITY ACROSS SOUTHERN
TN WILL CONTINUE TO MOVE ENE DURING THE AFTERNOON.  CONVECTION OVER
NEAR KHOP/KCKV WILL PUSH EAST AND AFFECT KBWG BETWEEN 18-22Z.

FURTHER NORTH AT THE KSDF TERMINAL...CURRENT THUNDERSTORM ACTIVITY
CONTINUES TO MOVE TO THE NORTHEAST.  ADDITIONAL DEVELOPMENT SEEMS
LIKELY ACROSS WEST CENTRAL KY THIS AFTERNOON AND MAY AFFECT KSDF
BETWEEN 18-22Z AS WELL.

MVFR TO HIGH IFR CIGS/VSBYS WILL BE POSSIBLE. IT SHOULD BE NOTED
THAT DUE TO LOW FREEZING LEVELS...QUITE A BIT OF GRAUPEL HAS BEEN
REPORTED...SO ANY STORM MOVING THROUGH THE TERMINAL MAY PRODUCE THIS
AS WELL.

CONDITIONS SHOULD START TO IMPROVE AT ALL SITES AFTER 11/00Z AS
SYSTEM PULLS OFF TO THE EAST AND DRIER AIR STARTS TO FILTER IN FROM
THE NW.  SKIES SHOULD GO MOSTLY CLEAR BY 11/12Z.
