Area forecast discussion, Aug 11, 1:57 PM CDT, 1 hour 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
157 PM CDT MON AUG 11 2014

.DISCUSSION...
SHOWERS AND THUNDERSTORMS HAVE FORMED SHORT LINES DOWN THROUGH
WEST AND MIDDLE TENNESSEE ALONG WITH WESTERN KENTUCKY OUT AHEAD OF
A COOL FRONT THAT EXTENDS FROM JUST SOUTH OF THE OHIO RIVER IN FAR
WESTERN KENTUCKY DOWN ALONG MISSISSIPPI RIVER JUST WEST OF MEMPHIS.
DEWPOINTS ARE IN THE MIDDLE 70S WITH PRECIPITABLE WATER AROUND 2
INCHES ALONG WITH PLENTY OF UPPER SUPPORT FOR LOCALLY HEAVY DOWNPOURS
THAT COULD LEAD TO PONDING OF WATER ON ROADWAYS AND LOW LYING
AREAS. THE HEAVIEST CONVECTION SO FAR TODAY HAS BEEN NORTHEAST
MIDDLE TENNESSEE NEAR THE KENTUCKY BORDER WHERE WE HAVE ISSUED
FLOOD ADVISORIES. SURFACE FRONT WILL TAKE ITS TIME MOVING EASTWARD
DURING THE AFTERNOON AND THIS EVENING BUT EXPECT TO SEE MORE
CONCENTRATION OF SHOWERS/STORMS OVER EASTERN AREAS AND PLATEAU
ONCE WE GET INTO THE EVENING HOURS AS MOISTURE TRANSPORT WILL BE
DIMINISHING OVER THE WEST. FRONT FINALLY PULLS EAST OF THE MID
STATE ON TUESDAY BUT UPPER TROUGH SHARPENS WITH GOOD LIFT OVER THE
AREA DURING THE DAY SO HAVE KEPT POPS GOING THROUGH THE DAYLIGHT
HOURS. TUESDAY NIGHT THROUGH THE REMAINDER OF THE WORK WEEK THE
UPPER TROUGH WILL DOMINATE THE EASTERN U.S. AS UPPER RIDGE GETS
PUMPED UP THROUGH CENTRAL U.S. EURO BUILDS UPPER RIDGE OVER
SOUTHEASTERN U.S NEXT WEEK.
