AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
315 AM CST THU JAN 10 2008

.DISCUSSION...
MAIN FORECAST CONCERNS ARE PRECIP CHANCES TODAY INTO TONIGHT...AND
PRECIP CHANCES AND TYPE LATE THIS WEEKEND.

NAM...GFS AND ECMWF ALL INDICATE INCREASING MOISTURE AND SHOWERS
QUICKLY DEVELOPING AND MOVING NORTHEAST ACROSS MOST OF THE PAH
FORECAST AREA BY LATE THIS MORNING AHEAD OF A LOW PRESSURE SYSTEM
MOVING ACROSS MISSOURI.  FAR WESTERN PORTIONS OF THE FA WILL SEE
JUST LIGHT AMOUNTS OF QPF...BUT RAINFALL AMOUNTS OF UP TO THREE
QUARTERS OF AN INCH WILL BE POSSIBLE ACROSS THE EASTERN HALF OF THE
AREA BY 00Z.  THUNDER WILL BE POSSIBLE MAINLY ACROSS SOUTHEAST
PORTIONS OF THE FA WHERE NAM AND GFS SOUNDINGS INDICATE LIFTED
INDICES WILL BE AROUND ZERO TO -2.

SOME LIGHT PRECIP MAY LINGER INTO TONIGHT...FALLING MAINLY AS LIGHT
RAIN.  SOUNDINGS AND 1000-850MB THICKNESS VALUES SHOW MINIMAL
CHANCES OF THE RAIN MIXING WITH SNOW...SO CONFINED A SMALL CHANCE OF
A RAIN/SNOW MIX TO NORTHERN PORTIONS OF SOUTHERN ILLINOIS AFTER
MIDNIGHT.  ANY QPF AMOUNTS TONIGHT WILL BE MINIMAL.

DRY CONDITIONS AND ABOVE SEASONAL TEMPERATURES CAN BE EXPECTED FOR
FRIDAY AND INTO THE WEEKEND.  BY SATURDAY NIGHT...GFS SHOWS A LOW
PRESSURE SYSTEM MOVING ACROSS NORTHERN PORTIONS OF THE PAH
FA...WHILE THE NAM AND ECMWF TAKE IT MUCH FARTHER NORTH.  BOTH GFS
AND ECMWF SHOW LIGHT PRECIP ACROSS THE AREA WITH THIS SYSTEM...WHILE
THE NAM KEEPS US DRY.  WILL CONTINUE SLIGHT CHANCE POPS FOR THE AREA
SATURDAY NIGHT AND SUNDAY.  SOUNDINGS INDICATE ALL RAIN WITH THIS
POSSIBLE EVENT...BUT THICKNESS VALUES IMPLY A POSSIBILITY OF A
RAIN/SNOW MIX FOR WESTERN AND NORTHERN PORTIONS OF THE FA SATURDAY
NIGHT...AND THE ENTIRE AREA ON SUNDAY.  WILL KEEP THIS MIX GOING FOR
NOW...SINCE CONFIDENCE IS CURRENTLY LOW OVERALL FOR THIS EVENT AND
ONLY HAVE SLIGHT CHANCES GOING ANYWAY.

ON MONDAY...GFS AND ECMWF SHOW AN APPROACHING TROF...WITH THE GFS
SOLUTION BEING THE FASTER OF THE TWO.  PREFER TO KEEP A DRY FORECAST
FOR NOW AND SEE WHAT THE NEXT COUPLE OF RUNS LOOK LIKE.

FOR TEMPS...STAYED CLOSE TO A MAV/MET COMPROMISE...WITH THEM BEING
IN DECENT AGREEMENT.  IN THE EXTENDED...JUST MADE SOME MINOR TWEAKS
BASED ON LATEST MEX GUIDANCE.
