350 PM CST SAT MAR 4 1989

   ...HEVAY RAINFALL TONIGHT AND SUNDAY...THEN MUCH COLDER...

A LOW PRESSURE SYSTEM HAS DEVELOPED MUCH FURTHER SOUTH THAN WAS EARLIER
ANTICIPATED ALONG A COLD FRONT THAT STRETCHED FROM NEAR MEMPHIS TO
LAKE CHARLES TO BROWNSVILLE LATE THIS AFTERNOON.

THE FRONT IS EXPECTED TO BECOME NEARLY STATIONARY ALONG THE MISSISSIPPI
RIVER TONIGHT AS THE LOW NEAR BROWNSVILLE RACES NORTHEAST. ALSO...A
VERY POWERFUL UPPER LEVEL LOW WILL BE APPROACHING FROM WEST TEXAS.

THE COMBINATION OF ALL THESE WEATHER FEATURES HAS RESULTED IN HEAVY
THUNDERSTORMS TO DEVELOP ACROSS SOUTHWEST LOUISIANA. THESE STORMS
WILL INCREASE AND NUMBERS AND INTENSITY AS THEY MOVE THROUGH THE
STATE TONIGHT. SOME OF THE STORMS WILL LIKELY BECOME SEVERE. ALSO...
HEAVY RAINFALL OVER NEARLY SATURATED GROUNDS ARE ANTICIPATED. THUS...
A FLASH FLOOD WATCH HAS BEEN ISSUED FOR THAT PORTION OF MISSISSIPPI
ALONG AND NORTH OF INTERSTATE-20.

THE SURFACE LOW PRESSURE SYSTEM IS FORECAST TO BE LOCATED NEAR MCCOMB
BY SUNRISE SUNDAY MONRING AND WILL MOVE NORTHEAST OUT OF THE STATE
SUNDAY AFTERNOON. MODERATE TO HEAVY RAINFALL WILL CONTINUE THROUGH
THE DAY SUNDAY.

BEHIND THE FRONT...VERY COLD AIR WILL INVADE THE STATE. THE
PRECIPITATION WILL LIKELY CHANGE OVER TO SNOW IN NORTHWEST MISSISSIPPI
BY SUNDAY AFTERNOON. LIGHT SNOW IS POSSIBLE AS FAR SOUTH AS INTERSTATE
20 SUNDAY NIGHT AND MONDAY. IT APPEARS THAT ALTHIUGH THIS IS A VERY
POWERFUL SYSTEM...THAT SNOW AMOUNTS WILL BE LIGHT. SOME MEASURABLE
AMOUNTS OF SNOW ARE POSSIBLE NEAR THE MISSISSIPPI-TENNESSEE BORDER
BY MONDAY MORNING.

ANOTHER FACTOR WITH THIS STORM IS MORE ARCTIC AIR THAT WILL PUT A REAL
CHILL ON THE STATE...ESPECIALLY SUNDAY NIGHT AND MONDAY. WITH NORTHERLY
WINDS OF 15 TO 25 MPH EXPECTED...WIND CHILLS WILL FALL CLOSE TO ZERO
ACROSS THE NORTHERN AND CENTRAL SECTIONS BY MONDAY MORNING.

SOME RATHER DRAMATIC zWEATHER CHANGES WILL BE TAKING PLACE ACROSS
MISSISSIPPI DURING THE NEXT 24 HOURS AND ALL MISSISSIPPIANS ARE URGED
TO LISTEN TO THE LATEST WEATHER FORECASTS AND STATEMENTS.
