AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
239 PM CDT FRI MAR 30 2007

.DISCUSSION...

THIS AFTERNOON HIGH PRESSURE WAS CENTERED OVER THE SOUTHEAST U.S. AS
A DEVELOPING STORM SYSTEM WAS LIFTING NORTHWARD OUT OF THE SOUTHERN
PLAINS. OUT OF THIS SYSTEM A WEAK W-E ORIENTED WARM FRONT WAS DRAPED
ACROSS THE NORTHERN SECTIONS OF OUR CWA AND A COLD FRONT TRAILED
SOUTHWARD INTO FAR SOUTHERN TEXAS. THIS EVENING SHOWERS AND
THUNDERSTORMS SHOULD BE MORE WIDESPREAD ACROSS THE NORTHERN SECTIONS
IN THE VICINITY OF THE WARM FRONT AND OVER THE WESTERN SECTIONS
WHERE INSTABILITY WILL BE THE GREATEST AS WELL AS THE PROXIMITY TO
THE DYNAMICS OF THE APPROACHING SYSTEM. AFTER MIDNIGHT THUNDERSTORMS
CHANCES SHOULD DIMINISH AS INSTABILITY WEAKENS AND THE WARM FRONT
LIFTS NORTH.

ON SATURDAY AS THE AFOREMENTIONED SYSTEM LIFTS NORTHWARD ACROSS THE
CENTRAL PLAINS...IT WILL PUSH ITS ASSOCAITED COLD FRONT INTO THE FAR
WESTERN SECTIONS OF OUR CWA BY 00Z SUNDAY. AS A RESULT...THE CHANCES
FOR PRECIP WILL INCREASE ON SATURDAY FROM WEST TO EAST AS THE FRONT
APPROACHES. INSTABILITY VALUES ARENT FORECAST TO BE THAT IMPRESSIVE
...BUT WITH JET DYNAMICS AND FAVORABLE SHEAR...ORGANIZED STORMS ARE
A GOOD BET WITH THE POSSIBILITY OF SOME STORMS BECOMING
SEVERE.

WITH PARENT SYSTEM DRIVING NEARLY DUE NORTH...THE EASTWARD PROGRESS
OF THE COLD FRONT WILL BE SLOW. THEREFORE...PRECIP WILL SLOWLY CLEAR
FROM WEST TO EAST SATURDAY NIGHT WITH THE POSSIBILITY OF THE LAST
BIT LINGERING OVER THE EXTREME SOUTHEAST CORNER OF THE CWA SUNDAY
MORNING.

HIGH PRESSURE SHOULD KEEP THE REGION DRY THROUGH MONDAY NIGHT. KEPT
POPS IN FOR TUESDAY AND TUESDAY NIGHT AS THE NEXT STORM SYSTEM
CROSSES THE HEARTLAND. FROM WEDNESDAY THROUGH FRIDAY...WITH PRESSURE
AT THE SURFACE AND NORTHWEST FLOW ALOFT...MODELS ARE CURRENTLY
KEEPING OUR CWA DRY AND TEMPERATURES AT OR BELOW SEASONAL NORMS.

FOR TEMPERATURES...GENERALLY WENT WITH A COMPROMISE BETWEEN THE GFS
AND MET MOS NUMBERS...WITH A SLIGHT LEANING TOWARD THE GFS.
