Area forecast discussion, Sep 6, 1:28 PM CDT, 3 hours 19 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 128 PM CDT THU SEP 6 2001 PRIMARY PROBLEM FOR THIS FORECAST CONTINUES TO BE POPS THROUGH THE WEEKEND. A VIGOROUS UPPER-LEVEL LOW WILL RACE EASTWARD INTO THE CENTRAL ROCKIES BY FRIDAY AFTERNOON. THIS WILL HELP PUSH THE UPPER-LEVEL HIGH EAST OF THE AREA...AND ALLOW SOUTHWEST FLOW TO DEVELOP IN ITS PLACE. THIS WILL ALSO CAUSE A WEAK UPPER LOW OVER THE TEXAS PANHANDLE TO EJECT NORTHEAST WHICH WILL PRODUCE SCATTERED COVECTION ACROSS THE REGION THIS AFTERNOON AND EVENING. FRIDAY NIGHT A SECOND TROUGH DIVES SOUTH OUT OF CANADA AND CARVES OUT A RATHER LARGE TROUGH IN THE CENTRAL U.S. MEANWHILE THE ORIGINAL LOW WILL ROTATE NORTHEAST AROUND THE DEVELOPING TROUGH AND PUSH A COLD FRONT ACROSS THE ENTIRE AREA SATURDAY. WITH SOUTHWEST FLOW DEVELOPING ALOFT AND SOUTHERLY FLOW INCREASING AT THE SURFACE...MOISTURE WILL BE ON THE INCREASE...WITH MODELS SHOWING PRECIPITABLE WATER VALUES BETWEEN 1.5 AND 2 INCHES TONIGHT THROUGH SATURDAY. WITH THE MAIN SFC/UPPER LOWS PASSING WELL TO OUR NORTH AND WEST...THERE WILL BE LITTLE IN THE WAY OF LIFT OR INSTABILITY UNTIL THE FRONT ARRIVES SATURDAY. THE ONLY LIFT THROUGH FRIDAY NIGHT WILL BE ASSOCIATED WITH MINOR DISTURBANCES IN THE STRENGTHENING SOUTHWEST FLOW ALOFT. STRONG COLD FRONT WILL RACE ACROSS THE AREA SATURDAY...AND WITH GOOD UPPER-LEVEL SUPPORT...WIDESPREAD SHOWERS AND THUNDERSTORMS ARE LIKELY. BEHIND THE FRONT MODELS SHOW MOISTURE LINGERING THROUGH SUNDAY MORNING. THIS COMBINED WITH THE UPPER TROF PASSAGE AND ASSOC POSITIVE VORTICITY ADVECTION COULD PRODUCE SCATTERED SHOWERS...SO WILL LEAVE THE MENTION OF MORNING SHOWERS ON SUNDAY. BEYOND SUNDAY HIGH PRESSURE AT THE SURFACE AND INCREASED RIDGING ALOFT WILL SERVE TO PRECLUDE THE PRODUCTION OF PRECIPITATION FROM MONDAY THROUGH THURSDAY. FWC/MAV MOS NUMBERS VERY CLOSE SO WILL FOLLOW CLOSELY FOR LOWS AND GO SLIGHTLY ABOVE GUIDANCE FOR HIGHS. .PAH...NONE. JAP
