PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1158 AM CDT THU APR 10 2008
...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE OZARKS AND LOWER
MISSISSIPPI VALLEY INTO THE LOWER TENNESSEE AND LOWER OHIO VALLEYS
TODAY THROUGH TONIGHT...
THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF A FEW STRONG...LONG-TRACK TORNADOES...LARGE HAIL AND
DAMAGING WINDS OVER PARTS OF THE OZARKS AND LOWER MISSISSIPPI VALLEY
INTO THE LOWER TENNESSEE AND LOWER OHIO VALLEYS TODAY THROUGH
TONIGHT.
THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
EASTERN ARKANSAS
SOUTHERN ILLINOIS
WESTERN KENTUCKY
NORTHERN LOUISIANA
SOUTHEAST MISSOURI
NORTHERN MISSISSIPPI
WEST TENNESSEE
ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM...THE WESTERN GULF
COAST NORTH INTO THE LOWER MISSOURI AND MID MISSISSIPPI VALLEY
THE STRONG JET STREAM DISTURBANCE IN PART RESPONSIBLE FOR
YESTERDAY'S AND THIS MORNING'S INTENSE STORMS IN TEXAS AND OKLAHOMA
WILL CONTINUE NORTHEAST INTO IOWA AND MISSOURI BY EARLY FRIDAY. AT
THE SAME TIME...THE SURFACE LOW PRESSURE CENTER ASSOCIATED WITH THE
DISTURBANCE...OVER CENTRAL KANSAS..WILL STRENGTHEN AND MOVE TO NEAR
DES MOINES.
A BROAD CURRENT OF SOUTHERLY WINDS SPREADING NORTH AHEAD OF THE
OKLAHOMA LOW WILL FEED VERY WARM AND HUMID AIR INTO THE MID
MISSISSIPPI...LOWER OHIO AND TENNESSEE VALLEYS LATER TODAY AND
TONIGHT. AT THE SAME TIME...A BELT OF 130 MPH JET STREAM WINDS
SKIRTING THE EDGE OF THE UPPER LEVEL DISTURBANCE WILL SWEEP NORTH
AND EAST INTO PARTS OF ARKANSAS...MISSOURI AND ILLINOIS.
THE COMBINATION OF INCREASINGLY WARM AND HUMID AIR WITH VERY STRONG
ENVIRONMENTAL WINDS THAT CHANGE DIRECTION WITH HEIGHT WILL CREATE A
FAVORABLE SETUP FOR LONG-LIVED ROTATING THUNDERSTORMS. SOME OF
THESE SUPERCELL STORMS WILL CONTINUE EAST AND NORTH INTO
ARKANSAS...SOUTHERN MISSOURI AND NORTHERN LOUISIANA FROM OVERNIGHT
ACTIVITY IN TEXAS AND OKLAHOMA. OTHER STORMS LIKELY WILL FORM LATER
THIS AFTERNOON THROUGH TONIGHT ACROSS PARTS OF MISSISSIPPI
...TENNESSEE...KENTUCKY AND ILLINOIS. A FEW OF THE STORMS WILL BE
CAPABLE OF PRODUCING STRONG AND POSSIBLY LONG-LIVED TORNADOES...IN
ADDITION TO DAMAGING WINDS AND LARGE HAIL.
ELSEWHERE...A SEPARATE AREA OF SEVERE STORMS...INCLUDING
SUPERCELLS...MAY FORM THIS AFTERNOON OVER NORTHEAST
KANSAS...SOUTHEAST NEBRASKA...SOUTHERN IOWA AND NORTHWEST MISSOURI.
THESE MAY YIELD HAIL...LOCALLY DAMAGING WIND AND POSSIBLY A TORNADO
OR TWO THROUGH EARLY TONIGHT.
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.

VALID 111200Z - 121200Z
...THERE IS A SLGT RISK OF SVR TSTMS FROM THE ERN GREAT LAKES SWWD
THROUGH THE OH/TN VALLEY INTO THE CENTRAL GULF COASTAL STATES......
...SYNOPSIS...
BROAD LARGE SCALE LONGWAVE TROUGH WILL PROGRESS EWD ACROSS THE
CENTRAL PORTIONS OF THE COUNTRY...AS A CLOSED AND NEARLY VERTICALLY
STACKED CYCLONE SHIFTS SLOWLY NEWD FROM IA INTO LOWER MI DURING THE
PERIOD. ASSOCIATED COLD FRONT WILL TRANSITION EWD ACROSS THE OH/TN
VALLEYS AND CENTRAL GULF COASTAL REGION. EAST OF THE LOW AND AHEAD
OF THE SURFACE FRONT...A WARM FRONT WILL LIFT NWD INTO THE SRN GREAT
LAKES EWD INTO NRN PA/WRN NY DURING THE DAY.
...OH VALLEY/ERN GREAT LAKES REGION...
VERY STRONG ENVIRONMENTAL WINDS...100KT AT 500 MB AND 40-50KT AT 850
MB...WILL RESULT IN SUFFICIENT SHEAR FOR SEVERE STORMS. AS WARM
FRONT LIFTS NWD DURING THE DAY...WARM SECTOR DEWPOINTS IN THE UPPER
50S/LOWER 60S COMBINING WITH DIURNAL HEATING WILL YIELD MODERATE
INSTABILITY DURING THE AFTERNOON HOURS. THE AMOUNT OF SHEAR AND
INSTABILITY...PLUS FORCING ASSOCIATED WITH UPPER JET SHOULD SUPPORT
SUPERCELLS. HOWEVER...DEEP SWLY UNIDIRECTIONAL WINDS ABOVE THE
BOUNDARY LAYER IS LIKELY TO BE MORE SUPPORTIVE OF FAST MOVING
MULTICELL CLUSTERS/BOWING LINE SEGMENTS...WITH DAMAGING WINDS AND
SOME HAIL EXPECTED TO BE THE PRIMARY THREATS. HOWEVER...RELATIVELY
STRONG LOW LEVEL SHEAR MAY FAVOR BRIEF TORNADOES WITHIN BOWING
SEGMENTS AND ALSO ALONG WARM FRONT...WHERE LOW LEVEL SHEAR WILL BE
MAXIMIZED.
THE STRONG KINEMATICS/THERMODYNAMICS AND FORCING SUGGEST A FEW
HIGHER END WIND EVENTS...AND EVEN A STRONG TORNADO OR TWO...ARE
POSSIBLE. THEREFORE...IF THE INSTABILITY/HEATING OCCURS AS CURRENTLY
FORECAST BY THE MODELS...A MODERATE RISK MAY BE NEEDED FOR A PORTION
OF THE AREA IN LATER OUTLOOKS. THE CONCERN AT THIS TIME FOR A HIGHER
RISK IS CONVECTION TONIGHT/FRIDAY MORNING MAY RESULT IN RESIDUAL
CLOUDS LINGERING INTO THE AFTERNOON...WHICH WOULD REDUCE THE AMOUNT
OF HEATING AND THE CONSEQUENT SEVERE THREAT.
...LOWER OH/TN VALLEYS SWD ACROSS THE CENTRAL GULF COAST STATES...
SCATTERED THUNDERSTORMS ARE LIKELY TO BE ONGOING IN THE MORNING
ACROSS THE LOWER MS VALLEY AND POSSIBLY NEWD INTO MIDDLE TN VALLEY
IN ASSOCIATION WITH SURFACE FRONT AND FORCING LOCATED WITHIN RIGHT
ENTRANCE REGION OF UPPER JET. THESE STORMS ARE EXPECTED TO INTENSIFY
DURING THE DAY AS AIR MASS WARMS AND DESTABILIZES... MLCAPES FROM
1000-2000 J/KG MLCAPE...AHEAD OF EWD MOVING COLD FRONT. DEEP SWLY
TROPOSPHERIC WINDS AND STRONG CONVERGENCE ALONG THE FRONT IS LIKELY
TO RESULT IN A LINE OF STORMS DEVELOPING... WITH DAMAGING WINDS THE
PRIMARY HAZARD. THOUGH ENVIRONMENTAL CONDITIONS WOULD ALSO SUPPORT A
SEVERE THREAT ACROSS TN/KY... WEAKER FORCING ACROSS THIS AREA MAY
RESULT IN LESS OF A SEVERE THREAT HERE THAN ACROSS THE CENTRAL GULF
COAST AND UPPER OH VALLEY.

URGENT - IMMEDIATE BROADCAST REQUESTED
SEVERE THUNDERSTORM WATCH NUMBER 191
NWS STORM PREDICTION CENTER NORMAN OK
230 PM CDT THU APR 10 2008
THE NWS STORM PREDICTION CENTER HAS ISSUED A
SEVERE THUNDERSTORM WATCH FOR PORTIONS OF
PARTS OF SOUTHERN IOWA
PARTS OF EASTERN KANSAS
MUCH OF CENTRAL AND WESTERN MISSOURI
SMALL PART OF SOUTHEAST NEBRASKA
EFFECTIVE THIS THURSDAY AFTERNOON AND EVENING FROM 230 PM UNTIL
900 PM CDT.
HAIL TO 2 INCHES IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70
MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.
THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 100
STATUTE MILES EAST AND WEST OF A LINE FROM 60 MILES WEST
NORTHWEST OF DES MOINES IOWA TO 10 MILES SOUTH OF SPRINGFIELD
MISSOURI. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU1).
REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY
DO PRODUCE TORNADOES.
OTHER WATCH INFORMATION...CONTINUE...WW 189...WW 190...
DISCUSSION...STRONG SURFACE/UPPER LOW WILL BE ROTATING NEWD THRU KS
INTO ERN NE/IA THIS EVENING. VERY STRONG DEEP LAYER SHEAR AND
MARGINAL INSTABILITY WILL SUPPORT DEVELOPMENT OF SEVERE
THUNDERSTORMS ALONG LEADING EDGE OF DRIER AIR MOVING THRU ERN KS.
PRIMARY THREAT WILL BE DAMAGING WINDS/LARGE HAIL AS STORMS INCREASE
IN NUMBER AND INTENSITY MOVING RAPIDLY NNEWD THRU THE WATCH.
AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
TO 2 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60
KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 450. MEAN STORM
MOTION VECTOR 21045.
