NWS predicting a possible "significant severe weather outbreak" on Friday

...SIGNIFICANT SEVERE WEATHER OUTBREAK POSSIBLE ACROSS THE MID-SOUTH LATE TONIGHT AND FRIDAY...

A STRONG AREA OF LOW PRESSURE WILL FORM IN THE SOUTHERN PLAINS TODAY AND MOVE NORTHEAST INTO THE CENTRAL PLAINS TONIGHT. AN ASSOCIATED WARM FRONT WILL SURGE NORTH ACROSS PORTIONS OF THE LOWER MISSISSIPPI VALLEY LATE TONIGHT. AS THIS WARM FRONT APPROACHES THE MID SOUTH... SHOWERS AND THUNDERSTORMS ARE EXPECTED TO INCREASE IN COVERAGE LATE TONIGHT ACROSS AREAS ALONG AND WEST OF THE MISSISSIPPI RIVER DELTA. CONDITIONS WILL BE FAVORABLE FOR SHOWERS AND THUNDERSTORMS TO BECOME SEVERE. THE MAIN THREATS LATE TONIGHT ACROSS THE MID-SOUTH WILL BE LARGE HAIL AND DAMAGING WINDS.

THIS WARM FRONT IS EXPECTED TO MOVE THROUGH THE REMAINDER OF THE MID-SOUTH FRIDAY MORNING AS THE POTENT AREA OF LOW PRESSURE EJECTS OUT OF THE CENTRAL PLAINS AND MOVES INTO THE MIDDLE MISSISSIPPI VALLEY. A TRAILING COLD FRONT WILL MOVE THROUGH THE MID-SOUTH FRIDAY AFTERNOON AND EVENING. AN UNSTABLE ATMOSPHERE COMBINED WITH FAVORABLE WIND SHEAR WILL PRODUCE CONDITIONS VERY FAVORABLE FOR THUNDERSTORMS TO QUICKLY BECOME SEVERE. LARGE HAIL... DAMAGING WINDS AND TORNADOES ARE ALL POSSIBLE ON FRIDAY. A MORE SIGNIFICANT TORNADO THREAT MAY DEVELOP ACROSS THE AREA ESPECIALLY EAST OF THE MISSISSIPPI RIVER FRIDAY AFTERNOON.

NOW IS THE TIME TO PREPARE FOR THE POSSIBILITY OF SEVERE THUNDERSTORMS. KNOW WHAT TO DO AND WHERE TO GO IF SEVERE WEATHER THREATENS. MAKE SURE YOUR NOAA WEATHER RADIO IS IN WORKING CONDITION... AND REMEMBER MOBILE HOMES ARE ESPECIALLY NOT A SAFE PLACE TO BE WHEN THERE IS THE THREAT OF DAMAGING WINDS AND TORNADOES.

STAY TUNED TO NOAA WEATHER RADIO... COMMERCIAL RADIO... OR TELEVISION FOR THE LATEST WEATHER INFORMATION ON THIS DEVELOPING WEATHER SITUATION. THE LATEST WEATHER INFORMATION ON THE WEB MAY BE OBTAINED AT WEATHER.GOV/MEMPHIS.
