...WARM FRONT TO TRIGGER SHOWERS AND THUNDERSTORMS LATE...

A WARM FRONT WILL LIFT SLOWLY NORTH ACROSS THE REGION TODAY.  A LOW
LEVEL JET WILL DEVELOP TONIGHT...ALLOWING GULF MOISTURE TO SURGE
NORTHWARD INTO THE REGION. THIS MOISTURE AND JET ENERGY WILL INTERACT
WITH THE FRONT TO PRODUCE WIDESPREAD SHOWERS AND THUNDERSTORMS...MAINLY
TONIGHT THROUGH MONDAY.

THE STRONGEST OF THE THUNDERSTORMS ARE EXPECTED TO OCCUR WEST OF THE
MISSISSIPPI RIVER...AND GENERALLY ALONG AND NORTH OF INTERSTATE 80.
THE MAIN THREAT WITH THESE THUNDERSTORMS IS HEAVY RAIN.  THE THERMAL
PROFILE ALOFT WILL ALSO MAKE IT POSSIBLE FOR DAMAGING HAIL DURING THE
LATE AFTERNOON AND EVENING HOURS.  SPOTTER ACTIVATION MAY BE NEEDED THIS
AFTERNOON AND EVENING.

BEYOND TONIGHT...A VERY ACTIVE PATTERN WILL HOLD INTO MIDWEEK...WITH
THE FRONT LINGERING IN THE AREA.  THERE IS THE POTENTIAL FOR HEAVY
RAINFALL DURING THIS TIME...AND CURRENT PROJECTIONS INDICATE WIDESPREAD
RAINFALL TOTALS OF 3 INCHES POSSIBLE BY LATE WEDNESDAY...WITH ISOLATED
HIGHER AMOUNTS POSSIBLE.

THIS EXTENDED PERIOD OF RAIN WILL GRADUALLY SATURATE SOILS ACROSS
THE REGION...AND MAY LEAD TO LOCALIZED FLOODING AND GRADUAL SIGNIFICANT
RISES ON AREA RIVERS.

STAY TUNED TO NOAA WEATHER RADIO...OR YOUR FAVORITE RADIO OR
TELEVISION STATION FOR LATER FORECASTS AND UPDATES ON THIS DEVELOPING
SITUATION.
