I'm not going to try to keep up with the thunderstorm warnings of winds 60+ or below that unless something of signficance is contained in the bulletin. Too many of those hit at once so will go with 70+ winds on this round...and tornado warnings naturally.

*If any severe weather is near any of our members/family I'll post that info also, no matter the wind speeds.

1057 AM CDT FRI JUN 19 2009

AREAS AFFECTED...FAR NERN KS THROUGH NRN MO INTO W-CNTRL IL

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 191557Z - 191730Z

THE THREAT FOR SEVERE STORMS CAPABLE OF MAINLY DAMAGING WINDS AND
HAIL IS EXPECTED TO INCREASE ACROSS DISCUSSION AREA FROM LATE
MORNING THROUGH THE AFTERNOON. CONVECTIVE TRENDS ARE BEING
MONITORED FOR A POSSIBLE WW.

15Z MESOANALYSIS INDICATED A RATHER COMPLEX SURFACE PATTERN OWING TO
THE PRESENCE OF RESIDUAL OUTFLOW BOUNDARIES REMNANT FROM NOCTURNAL
TSTM ACTIVITY. THE MOST SIGNIFICANT OF THESE BOUNDARIES IS RATHER
WELL-DEFINED /PER VISIBLE IMAGERY/ FROM NEAR OR JUST N OF THE MKC
METRO AREA NEWD TO NEAR UIN. RECENT TRENDS IN REGIONAL RADAR
IMAGERY INDICATE TSTMS GRADUALLY INCREASING IN COVERAGE AND
INTENSITY FROM NE OF MKC TO NEAR IRK...LIKELY DUE TO ENHANCED
LOW-LEVEL ASCENT N OF OUTFLOW BOUNDARY ALONG 45 KT WSWLY LLJ /PER
AREA PROFILERS AND VWPS/.

BASED ON 12Z TOP/SGF SOUNDINGS...INFLOW AIR MASS IS ALREADY
MODERATELY UNSTABLE OWING TO THE PRESENCE OF A MOIST BOUNDARY LAYER
AND MIDLEVEL LAPSE RATES AROUND 7 C/KM. THIS INSTABILITY IN
CONJUNCTION WITH THE SUSTAINED LOW-LEVEL WAA AND INCREASED FORCING
FOR ASCENT ASSOCIATED WITH APPROACHING UPSTREAM SHORT WAVE TROUGH
ALL SHOULD CONTRIBUTE TO A CONTINUED INCREASE IN STORM COVERAGE AND
INTENSITY LATE THIS MORNING INTO AFTERNOON.

CURRENT LATHROP MO PROFILER IS LIKELY REPRESENTATIVE OF AMBIENT
KINEMATIC ENVIRONMENT...FEATURING LARGELY UNIDIRECTIONAL DEEP WSWLY
WIND FIELDS AND AROUND 50 KT OF DEEP-LAYER SHEAR. AS SUCH...SETUP
WILL FAVOR THE DEVELOPMENT OF ORGANIZED STORMS INCLUDING BOWS AND
PERHAPS SUPERCELL STRUCTURES CAPABLE OF MAINLY DAMAGING WINDS AND
HAIL.

1153 AM CDT FRI JUN 19 2009

...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE MID MISSISSIPPI
VALLEY...THE OHIO VALLEY...AND THE CENTRAL APPALACHIANS THROUGH
TONIGHT...

THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF DAMAGING WINDS...LARGE HAIL...AND TORNADOES FROM THE
MID MISSISSIPPI VALLEY INTO THE OHIO VALLEY AND CENTRAL APPALACHIANS
THROUGH TONIGHT.

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

SOUTHEASTERN IOWA
NORTHERN AND CENTRAL ILLINOIS
NORTHERN AND CENTRAL INDIANA
NORTHEASTERN MISSOURI
MUCH OF OHIO
EXTREME SOUTHWESTERN PENNSYLVANIA
WESTERN WEST VIRGINIA

ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM THE
CENTRAL/SOUTHERN PLAINS TO THE MID ATLANTIC COAST.

A SEASONABLY STRONG JET STREAM DISTURBANCE...MOVING THROUGH THE
CENTRAL PLAINS...WILL TRACK EASTWARD INTO THE MID MISSISSIPPI VALLEY
TONIGHT...BEFORE REACHING THE NORTHERN OH VALLEY EARLY SATURDAY.

AHEAD OF THE DISTURBANCE...A VERY WARM...MOIST...AND UNSTABLE AIR
MASS WILL BE SITUATED ACROSS THE MISSISSIPPI/OHIO VALLEYS AND
CENTRAL APPALACHIANS. AS DAYTIME HEATING FURTHER DESTABILIZES THE
ATMOSPHERE...NUMEROUS STRONG TO SEVERE THUNDERSTORMS WILL FORM
WITHIN THE AXIS OF INSTABILITY. CONDITIONS WILL BE FAVORABLE FOR A
FEW SUPERCELLS WITH LARGE HAIL AND EVEN A FEW TORNADOES. HOWEVER
...THE GREATER THREAT IS FOR THESE STORMS TO ORGANIZE INTO
LONG-LIVED...BOW-SHAPED COMPLEXES...WITH WIDESPREAD WIND
DAMAGE...SOME SIGNIFICANT...EXPECTED LATE THIS AFTERNOON AND
OVERNIGHT. THE HIGHEST THREAT FOR MORE CONCENTRATED AND INTENSE
SEVERE WEATHER WILL STRETCH FROM SOUTHEASTERN IOWA/NORTHEASTERN
MISSOURI EASTWARD INTO SOUTHWESTERN PENNSYLVANIA/WESTERN WEST
VIRGINIA.

STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS POTENTIALLY
VERY DANGEROUS SITUATION. THOSE IN THE THREATENED AREA ARE URGED TO
REVIEW SEVERE WEATHER SAFETY RULES AND TO LISTEN TO
