Area forecast discussion, Apr 23, 8:32 PM CDT, 3 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 832 PM CDT FRI APR 23 2004 ...MESOSCALE CONVECTIVE DISCUSSION... STRONG WARM AIR ADVECTION CONTINUES ABOVE A WARM FRONT OVER CENTRAL OKLAHOMA INTO WEST CENTRAL ARKANSAS. STRONG ISENTROPIC ASCENT ALONG WITH INTENSE MASS/MOISTURE CONVERGENCE BETWEEN 850-800MB CONTINUES TO AUGMENT THE RELATIVE LACK OF INSTABILITY. ACCORDING TO SPC MESOANALYSIS PAGE AND 0Z SGF SOUNDING MUCAPES ARE GENERALLY AOB 250MB...HOWEVER SHEAR CONTINUES TO BE IMPRESSIVE WITHIN THE CLOUD BEARING LAYER. HODOGRAPH FROM 0Z SOUNDING IS LONG AND STRAIGHT FROM 2-6KM AGL...WHICH EXPLAINS THE OCCASIONAL CELL SPLIT. ELEVATED SUPERCELLS WILL REMAIN A POSSIBILITY FOR THE NEXT SEVERAL HOURS. OBVIOUSLY THERE IS NO TORNADO THREAT GIVEN THE COLD AND VERY STABLE BOUNDARY LAYER...HOWEVER STORM SCALE ROTATION WILL LIKELY AUGMENT WEAK INSTABILITY AND ALLOW FOR SEVERE HAIL IN THE MORE INTENSE CELLS. FURTHER WEST...BOW ECHO CONTINUES TO CHARGE EASTWARD AT NEARLY 50 MPH. STORM IS CLEARLY ELEVATED...HOWEVER MUCH LIKE EARLIER TODAY SOME OF THE DAMAGING WINDS HAVE BEEN PENETRATING THE COLD STABLE LAYER AND MAKING IT INTO THE SURFACE. DISTANCE SPEED TOOL HAS THIS STORM ENTERING WESTERN CHEROKEE COUNTY BY 02Z. RECENT LSR OUT OF ICT HAD 70MPH WIND GUST WITH THIS BOW...SO IN ADDITION TO LARGE HAIL DAMAGING WINDS WILL ALSO BE A THREAT INTO CHEROKEE AND POSSIBLY AS FAR EAST AS JASPER COUNTY. ELEVATED INSTABILITY DECREASES PAST HIGHWAY 71 SO WIND THREAT AND IN ALL LIKELIHOOD THE STORM ITSELF SHOULD BEGIN TO WEAKEN AS IT MOVES INTO MISSOURI. .SGF WATCHES/WARNINGS/ADVISORIES... .MO...FLOOD WATCH FOR WESTERN TIER OF MO COUNTIES AND FOR SOUTHERN MO COUNTIES ROUGHLY ALONG AND SOUTH OF HIGHWAY 60 THROUGH SUN 6 AM. .KS...FLOOD WATCH THROUGH 6 AM SUNDAY.
