AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
236 PM CST TUE MAR 22 2005

.SHORT TERM (TONIGHT THROUGH FRIDAY)...
NEAR TERM CONCERN IS CONVECTIVE POTENTIAL THIS EVENING. 500 MB
CLOSED LOW CENTER SHOWED UP CLEARLY ON SATELLITE IMAGERY OVER NE
CORNER OF OKLAHOMA AT 19Z. A DRY SLOT WRAPPED NORTHWARD INTO SW
KENTUCKY AND THE MISSOURI BOOTHEEL. TEMPERATURES WERE RISING THROUGH
THE 60S IN THIS AREA OF CLEARING. 19Z METARS SHOWED SURFACE WARM
FRONT EXTENDED FROM CENTRAL ARKANSAS...EAST ACROSS KDYR AREA INTO
MIDDLE TENNESSEE.

BASED ON RUC MODEL...SURFACE LOW WILL TRACK EAST NORTHEAST ACROSS
KDYR THIS EVENING...PASSING NORTH OF KHOP LATER TONIGHT. THIS WILL
PLACE PARTS OF WRN KENTUCKY IN THE WARM SECTOR FOR SEVERAL HOURS.
MARGINAL SURFACE BASED INSTABILITY /RUC CAPES AOB 1000/ IN THE WARM
SECTOR OF WRN KENTUCKY WILL DEVELOP BY 00Z. SCATTERED STORMS MAY
FORM ALONG THE WARM FRONT AS IT MOVES NORTH...WITH POTENTIAL FOR
HAIL GIVEN THE COLD AIR ALOFT /500 MB TEMPS AROUND MINUS 20/. OVER
THE REMAINDER OF THE FORECAST AREA...ISOLATED ELEVATED STORMS WILL
PERSIST TONIGHT AS THE VERY COLD 500 MB LOW APPROACHES. HIGHEST
AREAL COVERAGE OF PRECIP ASSOCIATED WITH THE UPPER LOW WILL PROGRESS
EAST ACROSS THE REGION TONIGHT.

THE REMNANTS OF THE WEAKENING 500 MB SYSTEM WILL PASS ACROSS THE
FORECAST AREA WEDNESDAY. SOME LINGERING SHOWERS WILL OCCUR...MAINLY
IN THE MORNING. EXTENSIVE LOW CLOUDINESS IN THE COLD CYCLONIC FLOW
AROUND THE DEPARTING SURFACE LOW WILL RESULT IN UNSEASONABLY COOL
HIGHS.

WEAK SURFACE RIDGING WILL CROSS THE MISSISSIPPI VALLEY ON WEDNESDAY
NIGHT/EARLY THURSDAY. SURFACE DEW POINTS WILL ONLY FALL INTO THE
LOWER TO MID 30S. WITH LIGHT WINDS...SOME FOG MAY FORM UNDER AREAS
OF CLEAR SKY. WILL HOLD OFF ON MENTIONING THIS IN THE FORECAST.

A STRONG WARM ADVECTION PATTERN WILL DEVELOP THURSDAY AND CONTINUE
THROUGH EARLY FRIDAY. PLENTY OF MID LEVEL CLOUDINESS IS EXPECTED AS
THE MODELS SHOW STRONG OMEGA AT AND ABOVE 850 MB. STRONG ISENTROPIC
ASCENT IS INDICATED ON THE NAM 300K SURFACE...ALONG WITH DECENT
850/700 MB LAYER QG FORCING. THE GFS EVEN PRODUCES SOME LIGHT QPF
THURSDAY AFTERNOON. WILL KEEP THURSDAY AFTERNOON DRY...SIDING WITH
THE NAM...WHICH SHOWS VERY LOW 850 MB DEW POINTS. ELEVATED
INSTABILITY WILL INCREASE THURSDAY NIGHT...WHICH COULD YIELD SOME
WEAK CONVECTION AS A MID LEVEL SHORTWAVE PASSES BY TO THE NORTH.

LOW SHOWER AND THUNDERSTORM CHANCES WILL BE CONTINUED THROUGH FRIDAY
AS A SURFACE COLD FRONT REACHES THE FORECAST AREA. ALTHOUGH THE GFS
TAKES THE FRONT SOUTH OF THE KY BORDER BY MIDDAY...THIS LOOKS A BIT
FAST GIVEN THE WEAK PUSH BEHIND IT. WILL GO ALONG WITH THE
NAM...WHICH STALLS IT OVER WEST KENTUCKY DURING THE AFTERNOON.
PRECIP COVERAGE ALONG THE FRONT WILL BE VERY LIMITED UNTIL STRONGER
UPPER SUPPORT ARRIVES OVER THE WEEKEND /SEE LONG TERM DISCUSSION/.

&&

.LONG TERM (FRIDAY NIGHT THROUGH TUESDAY)...
QUAD STATE REGION WILL CONTINUE IN THE WET WEATHER PATTERN INTO THE
WEEKEND.  LATEST GFS DIFFERS QUITE A BIT FROM ITS PREVIOUS
RUN...TAKING A SURFACE LOW FROM THE SOUTHERN PLAINS THIS WEEKEND
FARTHER SOUTH AND LINGERING IT OVER THE SOUTHEASTERN U.S. INTO EARLY
NEXT WEEK...THUS KEEPING QPF ACROSS OUR REGION FOR SEVERAL DAYS.
ECMWF IS SIMILAR IN TRACK FROM ITS PREVIOUS RUN...THOUGH IS SLOWER
AND IS MORE IN LINE WITH THE PREVIOUS GFS RUN.  PREFER THIS
SOLUTION...THOUGH WILL SLOW IT DOWN EVEN MORE.  CONTINUED GOING
POPS...WITH MINOR TWEAKS...FRIDAY NIGHT THROUGH SATURDAY
NIGHT...THEN INTRODUCED LOW CHANCE POPS ON SUNDAY TO ACCOUNT FOR
SLOWER TIMING.  LEFT SUNDAY NIGHT THROUGH TUESDAY DRY...ALTHOUGH
THERE IS STILL PLENTY OF UNCERTAINTY...ESPECIALLY FOR THE SUNDAY
NIGHT INTO MONDAY TIME FRAME.

AS FOR TEMPS...MEX GUIDANCE IS TRENDING COOLER OVER THE WEEKEND DUE
TO THE GFS FORECAST LOW TRACK BEING FARTHER SOUTH.  SINCE THERE IS
LOW CONFIDENCE IN THIS SOLUTION...STAYED ABOVE MEX GUIDANCE THROUGH
THE WEEKEND INTO NEXT WEEK AND REALLY ONLY MADE MINOR TWEAKS TO
GOING EXTENDED TEMPS.
