.DAY ONE…TODAY AND TONIGHT…

THE MAIN MOISTURE AXIS RESPONSIBLE FOR THE 2 TO 3 INCHES OF
RAINFALL YESTERDAY WILL SHIFT WESTWARD INTO ALABAMA THIS MORNING.
THIS WILL ALLOW FOR A BRIEF BREAK FROM THE SUSTAINED MODERATE
RAINFALL ACROSS THE AREA…ESPECIALLY AREAS SOUTH AND EAST OF A
COLUMBUS TO ATHENS LINE. AS WE GET INTO THE LATE MORNING AND
AFTERNOON HOURS…REDEVELOPMENT OF SHOWERS AND SCATTERED
THUNDERSTORMS IS EXPECTED ACROSS THE EXTREME NORTHERN TIER AS WELL
AS ALONG WESTERN PORTIONS OF THE FORECAST AREA. AN ADDITIONAL 1 TO
2 INCHES WITH LOCALLY HIGHER AMOUNTS IS ANTICIPATED IN THESE
AREAS. IN ADDITION…A LOW LEVEL WIND CORE WILL LEAD TO THE
DEVELOPMENT OF ISOLATED STRONG STORMS DURING THE AFTERNOON HOURS.

WEATHER HAZARDS EXPECTED…

WILL LEAD TO ADDITIONAL FLASH FLOODING AND RIVER FLOODING.

ADDITIONAL RAINFALL AND THERE IS CONCERN THAT ACCUMULATING HIGH
RAINFALL TOTALS WILL LEAD TO SIGNIFICANT FLOODING ACROSS THE AREA. PERSONS
PLANNING OUTDOOR ACTIVITIES FOR THE WEEKEND SHOULD MONITOR THE
LATEST FORECASTS.
