CONTINUE TO BUILD INTO THE AREA FROM THE NW. COLD AIR ADVECTION

NICELY WITH PLENTY OF MINUTES OF SUNSHINE. HIGH TEMPERATURES A FEW
DEGREES BELOW NORMAL. NORTHWEST FLOW CONTINUES ALOFT. MID LEVEL

OVERNIGHT. LOW TEMPERATURES WILL BE NEAR 10 DEGREES BELOW NORMAL.

.LONG TERM (SUNDAY THROUGH FRIDAY)...NORTHWEST FLOW ALOFT WILL
CONTINUE OVER THE REGION INTO SUNDAY.  A WEAK BOUNDARY MOVING ACROSS
THE AREA MAY PROVIDE ENOUGH LIFT FOR SOME ISOLATED CONVECTION OVER
THE EAST TN MOUNTAINS LATE SUNDAY AFTERNOON.  A RIDGE OF HIGH
PRESSURE WILL SHIFT IN ON MONDAY AND WILL REMAIN THE MAIN WEATHER
FEATURE THROUGHOUT THE REST OF THE EXTENDED.  AS THE RIDGE BUILDS
IN...MOIST AIR WILL PUSH BACK INTO THE REGION.  THE ADDED LOW LEVEL
MOISTURE COMBINED WITH DAYTIME HEATING WILL ALLOW DIURNAL CONVECTION

OVER HIGHER TERRAIN.  AS FOR TEMPERATURES...A WARMING TREND WILL
ALLOW TEMPERATURES TO CLIMB ABOVE NORMAL BY THE END OF THE PERIOD.
