AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1040 AM CDT SUN MAY 28 2006

.DISCUSSION...
FORECAST ON TRACK.  MOISTURE IS BEING ADVECTED INTO THE AREA FROM
THE SOUTHWEST WITH PW FOR BNA ON THE ETA AND GFS MODELS INCREASING
TO 1.74 INCHES AT 18Z. AFTERNOON HEATING AND MOISTURE EXPECT THE
SUMMER TIME ISOLATED TO SCATTERED THUNDERSTORMS TO FORM THIS
AFTERNOON.  UPDATED THE TIMING WORDING FOR THE FIRST PERIOD
EASTERN ZONES WINDS. NO OTHER CHANGES NEEDED.

PREVIOUS DISCUSSION...
LATEST ANALYSIS SHOWING LL HIGH PRESSURE OVER MUCH OF THE EAST...
WITH A PRETTY VIGOROUS LOW MOVING INTO THE NORTHERN PLAINS. ALOFT
...ML/UL RIDGES NOW WORKING OVER THE MID-SOUTH.

NOT A WHOLE LOT OF CHANGE ON TAP FOR THE FORECAST AREA AS ML/UL
RIDGES MOVE JUST EAST TODAY AND HOLD THAT GENERAL POSITION
INTO THE MIDDLE OF THE WORK-WEEK...LEAVING THE AREA IN WARM...
HUMID...AND UNSTABLE REGIME. DEEPER MOISTURE SOURCES DO SURGE
IN FROM TIME TO TIME BUT LACK OF ANY GOOD LL FEATURES SHOULD KEEP
CONVECTION ISOLATED TO OCCASIONALLY SCATTERED OVER THE NEXT FEW
DAYS..AND MOSTLY IN PEAK HEATING.

RIDGES START A BREAK DOWN WEDNESDAY NIGHT AS LONG WAVE TROF AXIS
MAKES EASTBOUND MOVE. UPPER TROFS AND SURFACE BOUNDARY WILL
ENHANCE DEVELOPMENT THURSDAY/THURSDAY NIGHT...BUT THEN BRING A
BRIEF SHOT OF DRIER/COOLER AIR TO THE REGION ON FRIDAY.
