.PREV DISCUSSION...

FORECAST FOCUS CONTINUES TO BE ON RAIN EVENTS THROUGH THE WEEK.

AT 18Z FRONT REMAINED ACROSS FAR SOUTHERN IN. SKIES WERE MOSTLY
SUNNY ACROSS THE FORECAST AREA /FA/. RAIN REMAINED WELL SOUTH OF THE
FA.

MODELS IN DECENT AGREEMENT THROUGH THE EARLY PART OF THE FORECAST
THEN DIFFER ON STRENGTH/PLACEMENT OF THE SFC LOW BY THU. GFS APPEARS
TO BE A BIT STRONG...BUT ITS PLACEMENT IS SIMILAR TO THE
ECMWF/UKMET. THUS WILL GO WITH A BLEND OF THE MODELS BUT LEAN TOWARD
THE GFS TOWARD THU.

FRONT WILL LIFT NORTH INTO THE FA TONIGHT AS A WARM FRONT.
ISENTROPIC LIFT STRENGTHENS OVERNIGHT AS 850 FLOW INCREASES OVER THE
SFC FRONT. EXPECT RAIN TO DEVELOP FROM SOUTH TO NORTH WITH BEST
CHANCES OF RAIN AFTER MIDNIGHT. STRONG FRONTOGENESIS DEVELOPS ACROSS
NRN IN OVERNIGHT SO HEAVY RAIN THREAT POSSIBILITY CONTINUES ACROSS
THE NRN FA. WILL GO CATEGORIAL POPS ALL AREAS AND CONTINUE TO
MENTION HEAVY RAIN IN THE NRN FA. SOME INSTABILITY ALOFT SO THUNDER
WILL ALSO BE POSSIBLE.  WITH MODEL AGREEMENT IN EARLY PART OF PERIOD
WENT WITH A BLEND FOR LOW TEMPREATURES WHILE TRENDING SLIGHTLY
WARMER WITH CLOUDS AND PRECIPITATION MOVING IN OVERNIGHT.

FRONT WILL REMAIN ACROSS THE FA ON WED. CONTINUED FRONTOGENESIS AND
ISENTROPIC LIFT INTO EARLY AFTERNOON LEADS TO CATEGORIAL POPS ONCE
AGAIN. DURING THE AFTN LIFT WEAKENS SO PRECIP MAY BECOME LESS
WIDESPREAD. WILL WORD FORECAST WITH OCCASIONAL WORDING TO HINT AT
POSSIBLE DRY PERIODS. BUST POTENTIAL STILL STRONG FOR HIGH TEMPS AS
MODELS CONTINUE TO SHOW STRONG TEMP GRADIENT ACROSS THE FA.  VARIED
TEMPERATURES ACROSS THE FA TO ACCOUNT FOR FRONT WITH UPPER 50S
NORTH OF THE FRONT AND UP TO AROUND 70 DEGREES SOUTH OF THE FRONT.

FRONT FINALLY LIFTS NORTH WED NIGHT INTO THU PUTTING FA INTO WARM
SECTOR. RAIN STILL A GOOD BET WITH PLENTIFUL MOISTURE AND SOME LIFT.
WILL CONTINUE WITH LIKELY POPS. THU AFTN AND EVE LOOK TO BE WHEN THE
HIGHEST PROBABILITY EXISTS FOR ANY SEVERE WEATHER. DUE TO
UNCERTAINTIES CANNOT PIN DOWN TIMING...BUT IF THE LATER TIMING IS
RIGHT THREAT WILL NOT BE AS HIGH DUE TO DECREASED INSTABILITY. WILL
CONTINUE TO HIGHLIGHT IN HWO.  WITH CLOUD COVER FIRMLY IN PLACE
WEDNESDAY NIGHT...TEMPERATURES WILL NOT DROP OFF SIGNIFICANTLY AND
WENT CLOSER TO WARMER GUIDANCE NUMBERS.  TEMPERATURES WILL INCREASE
