SURROUNDING THE HIGH RISK AREA...THERE IS A MODERATE RISK OF SEVERE

RIVER VALLEY

A VOLATILE SEVERE THUNDERSTORM SITUATION IS UNFOLDING OVER EASTERN
PORTIONS OF THE PLAINS AND MUCH OF THE LOWER MISSOURI AND MID
MISSISSIPPI AND OHIO RIVER VALLEYS TODAY AND TONIGHT. AN UNUSUALLY
STRONG UPPER LEVEL TROUGH AND JET MAX WILL QUICKLY OVERSPREAD AN
UNSEASONABLY WARM AND MOIST SURFACE AIRMASS THIS AFTERNOON. WE
EXPECT THAT SEVERAL AREAS OF SIGNIFICANT SEVERE WEATHER WILL DEVELOP

THE MOST SIGNIFICANT OF WHICH WILL OCCUR OVER THE NORTHERN HALF OF
MISSOURI/EASTERN KANSAS AND FAR SOUTHERN IOWA INTO WEST CENTRAL
ILLINOIS AHEAD OF A DEEPENING LOW PRESSURE CENTER AND ITS
ACCOMPANYING WARM FRONT. SUPERCELLS WILL RAPIDLY DEVELOP MID TO LATE
AFTERNOON ALONG DRY LINE EASTERN KS AND EASTWARD ACROSS MISSOURI
VICINITY OF A WARM FRONT. THESE STORMS ARE EXPECTED TO RACE
EASTWARD INTO TONIGHT ACCOMPANIED BY POTENTIALLY VIOLENT...LONG
TRACK TORNADOES AND VERY LARGE HAIL.

OTHER POTENTIALLY TORNADIC SUPERCELLS ARE EXPECTED TO DEVELOP LATER
THIS AFTERNOON AND THIS EVENING ALONG A DRY LINE EXTENDING INTO
EASTERN OKLAHOMA AND NORTHEASTERN TEXAS. THESE WILL SPREAD A THREAT
OF SEVERE STORMS...INCLUDING DAMAGING TORNADOES...ACROSS ARKANSAS
INTO THE MID SOUTH/LOWER OHIO VALLEY THROUGH THE NIGHT.

THIS IS POTENTIALLY A VERY DANGEROUS SITUATION. THOSE IN THE
THREATENED AREA ARE URGED TO REVIEW SEVERE WEATHER SAFETY RULES AND
TO LISTEN TO RADIO...TELEVISION...AND NOAA WEATHER RADIO FOR
POSSIBLE WATCHES...WARNINGS...AND STATEMENTS LATER TODAY.
