Severe Weather Threat Saturday

* Severe weather will be possible across the Twin States during the day on Saturday as a powerful storm system moves our way.

Here is the latest Hazardous Weather Outlook from the NWS Jackson:

.DAYS TWO THROUGH SEVEN...FRIDAY NIGHT THROUGH
THURSDAY...

...DAYS TWO AND THREE...FRIDAY NIGHT THROUGH
SUNDAY NIGHT...

A SEVERE WEATHER OUTBREAK WILL BE POSSIBLE FROM
FRIDAY NIGHT INTO SATURDAY AS A MAJOR STORM SYSTEM
MOVES EAST ACROSS THE LOWER MISSISSIPPI RIVER VALLEY.
THE COMBINATION OF STRONG INSTABILITY AND WIND SHEAR
...AND THE PASSAGE OF A STRONG LOW PRESSURE SYSTEM...
WILL RESULT IN SEVERE THUNDERSTORMS ACROSS THE ENTIRE
OUTLOOK AREA.

ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE FRIDAY
NIGHT OVER PORTIONS OF NORTHEAST LOUISIANA AND SOUTHEAST
ARKANSAS...AS A WARM FRONT LIFTS NORTH ACROSS THE AREA.
RICH GULF MOISTURE WILL SURGE NORTHWARD SOUTH OF THE WARM
FRONTAL BOUNDARY ACROSS LOUISIANA... HELPING TO CREATE A
VERY UNSTABLE ENVIRONMENT. WITH STRONG WINDS ALOFT...ANY
STORMS THAT DEVELOP NEAR THE WARM FRONT WILL HAVE THE
POTENTIAL TO BECOME SUPERCELLS CAPABLE OF PRODUCING
SEVERE WEATHER.

THUNDERSTORM COVERAGE WILL INCREASE FURTHER EAST THROUGH
THE EARLY MORNING HOURS SATURDAY ALONG WITH THE RISK OF
SEVERE WEATHER...ESPECIALLY IN AREAS ALONG AND SOUTH OF
INTERSTATE 20 WHERE THE GREATEST RISK FOR LARGE HAIL...
DAMAGING WINDS...AND ISOLATED TORNADOES WILL EXIST. STRONG
TO SEVERE THUNDERSTORMS ARE EXPECTED TO ORGANIZE INTO A
LARGE THUNDERSTORM COMPLEX...WHICH WILL WORK ITS WAY SLOWLY
EAST ACROSS THE OUTLOOK AREA SATURDAY.

IN ADDITION TO THE SEVERE WEATHER...HEAVY RAINFALL COULD
BE A PROBLEM OVER THE ENTIRE OUTLOOK AREA AS THUNDERSTORMS
ARE EXPECTED TO BRING TWO TO THREE INCHES OF RAINFALL IN
JUST A FEW HOURS.
