Area forecast discussion, Jul 27, 2:00 AM CDT, 3 hours 50 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
200 AM CDT MON JUL 27 1998

NOCTURNAL MCS DEVELOPMENT CONTINUES TO BE THE MAIN FORECAST CONCERN.
QUASI STATIONARY FRONTAL BOUNDARY REMAINS DRAPED ACROSS THE OZARKS
INTO THE TENNESSEE VALLEY. PATTERN AT 850 MB IS MORE POORLY DEFINED
THAN PREVIOUS FEW NIGHTS...AND THIS MAY ACCOUNT FOR LESS IMPRESSIVE
CONVECTION OVER MISSOURI/ERN KANSAS THAN AT THIS TIME LAST NIGHT.
BOTH MESO-ETA AND ETA INDICATE THE STRONG 850 MB THETA-E GRADIENT
HAS SHIFTED NORTH INTO NRN MISSOURI AND CENTRAL ILLINOIS. 850
MOISTURE CONVERGENCE FIELDS ON BOTH MODELS ARE RELATIVELY
DISORGANIZED. NEVERTHELESS...CONVECTION SEEMS TO BE INCREASING FROM
THE MISSOURI BOOTHEEL NORTHWEST INTO SOUTH CENTRAL MISSOURI PER
LATEST RADAR AND LIGHTNING DATA.

GIVEN THE UNCERTAINTIES WITH RESPECT TO TIMING AND LOCATION OF
CONVECTION THIS MORNING...MAY NEED TO HOLD ONTO FLASH FLOOD WATCH
FOR PARTS OF SE MISSOURI THIS MORNING. RADAR CURRENTLY INDICATES
RAINFALL RATES UP TO AN INCH PER HOUR IN POF AREA. PAST
HISTORY/RECENT CLIMATOLOGY SUGGESTS THAT HEAVIEST PRECIP SHOULD
OCCUR EARLY THIS MORNING...THEN A RELATIVE BREAK THIS AFTERNOON AND
EVENING.

ANOTHER ROUND OF STORMS POSSIBLE TONIGHT AS FRONT REMAINS IN THE
AREA AND BASIC PATTERN SHOULD REMAIN UNCHANGED. MODELS DIFFER WITH
RESPECT TO MOVEMENT OF FRONT. AGREE WITH NGM AND MESO-ETA QPF
PROGS...WHICH KEEP HEAVIEST QPF FURTHER SOUTH TOWARD THE BOOTHEEL
AND EXTREME SW KENTUCKY.

TEMPS ONLY REACHED THE LOWER TO MID 70S SUNDAY DUE TO CLOUDS AND
RAIN. ONCE AGAIN...MOS GUIDANCE SEEMS TO BE UNDERPLAYING THE
EXTENSIVE CLOUDS AND PRECIP.
