Area forecast discussion, Apr 5, 11:51 AM CST, 2 hours 32 minutes before
AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE ST LOUIS MO 1251 PM CDT MON APR 5 2010 .UPDATE... /1212 PM CDT MON APR 5 2010/ RATHER COMPLEX SITUATION FOR AREA THIS AFTERNOON. ELEVATED STORMS CONTINUE TO TRUCK ACROSS NORTHEAST MISSOURI AND INTO WEST CENTRAL ILLINOIS AT THIS TIME...WHILE ELEVATED STORMS ARE ALSO TRYING TO FIRE ALONG THE I-44 CORRIDOR OVER MISSOURI FROM STL TO ROLLA. FORECAST SOUNDINGS INTO EARLY AFTERNOON SUGGEST THAT STORM CLUSTER NEAR PPQ WILL CONTINUE TO ROLL INTO CENTRAL IL...WHILE ELEVATED STORMS WILL BE PERCOLATING FROM STL AREA INTO S IL. SVR WX CONCERN WILL INITIALLY BE HAIL AND WIND WITH ELEVATED STORMS AND PERHAPS ROTATIING SUPERCELLS....BUT IF STORMS CAN BECOME MORE SURFACED BASED LOW LEVEL WILL CERTAINLY BE SUPPORTIVE OF A TORNADO THREAT. MEANWHILE...WILL ALSO BE WATCHING DEVELOPMENT OF INTENSE STORMS OVER NW MO THAT MAY THREATEN OUR N AREAS LATER THIS AFTERNOON AND THIS EVENING. SHEAR...INSTABILITY...AND LAPSE RATES PROGGED INTO THIS AREA ALL SUGGEST A FAIRLY GOOD THREAT OF SUPERCELLS WITH VERY FAVORABLE TURNING OF LO LVL WINDS AND FAIRLY STEEP MID LEVEL LAPSE RATES...BOTH SUGGESTING A PRONOUNCED TORNADO AND LARGE HAIL THREAT. MAIN QUESTION FOR THIS AREA IS EXACTLY WHERE THE AXIS OF STORMS WILL SET UP...BUT IT CERTAINLY APPEARS THAT OUR N 8 COUNTIES WILL BE UNDER THE GREATEST THREAT. TRUETT && .DISCUSSION... /418 AM CDT MON APR 5 2010/ PRIMARY CONCERN WITH THIS FCST PCKG IS POTENTIAL FOR STRONG TO SEVERE THUNDERSTORMS OVER THE NEXT FEW DAYS. SFC CDFNT WAS LOCATED NEAR THE I70 CORRIDOR EARLY THIS MORNING WITH A FEW THUNDERSTORMS JUST AHEAD OF THE FNT IN IN/IL/MO/KS. MARKED MOISTURE DIFFERENCE NOTED ACROSS THE BDRY WITH DEWPOINTS IN THE 60S ACROSS CENTRAL AND SRN MO AND IN THE 30S ACROSS SRN IA. BDRY WILL BEGIN LIFTING NWD TODAY AS A WMFNT...ACTING TO SPREAD THAT MOISTURE INTO NRN MO/SRN IA AHEAD OF AN APCHG TROF. ELEVATED -TSRA EXPECTED TO DVLP INVOF THE WMFNT TODAY WITH THE PCPN THREAT SHIFTING NWD WITH THE FNT AND MCONV ON NOSE OF H85 LLJ. STEADILY INCREASING SBCAPE AND ROBUST VALUES OF 0-6 KM SHEAR DURING THE AFTN/EVE SUGGEST THAT SEVERE WEATHER IS POSSIBLE WITH ANY STORMS THAT BECOME SFC BASED ACROSS NRN MO AND WEST CENTRAL IL. NEXT CHC FOR -TSRA WILL BE TOMORROW AFTN/EVE INTO WED AS SFC LOW OVER KS LIFTS NEWD AND SENDS A CDFNT THROUGH THE REGION. CURRENT THINKING IS THAT A LINE OF TSRA WILL DVLP AHEAD OF THE CDFNT WITH MODEL FCSTS OF CAPE AND SHEAR SUFFICIENT FOR STRONG TO SEVERE STORMS TO PERSIST ON TUE NIGHT AS THE LINE MOVES EWD. PCPN WILL END FM W TO E ON WED NIGHT BEHIND THE CDFNT AS THE UPPER LVL TROF MOVES THROUGH THE CENTRAL CONUS. TEMPERATURES WILL BE MUCH COOLER BEHIND THE FNT ON WED AND THU. NO CHANGES PAST 00Z FRI. KANOFSKY && .AVIATION... /1243 PM CDT MON APR 5 2010/ WARM FRONT DRAPED ALONG THE I-70 CORRIDOR IS MOVING SLOWLY NORTH. WINDS VEER SHARPLY FROM THE NORTHEAST TO THE SOUTH AS THE FRONT MOVES NORTH. SCATTERED THUNDERSTORMS WILL BE ONGOING ACROSS THE AREA THIS AFTERNOON...ENDING DURING THE EARLY EVENING. THINK ANY GIVEN POINT IN THE AREA HAS A 30-40% CHANCE OF SEEING A STORM THIS AFTERNOON. THE LOW LEVEL JET WILL REALLY RAMP UP TONIGHT...SO LOW LEVEL WIND SHEAR IS A CONCERN AFTER EARLY EVENING. STRONG AND GUSTY SOUTHWEST WINDS AND VFR CONDITIONS WILL PREVAIL ON TUESDAY. SPECIFICS FOR KSTL... HAVE A COUPLE OF THUNDERSTORMS HEADED TOWARD THE TERMINAL AT THIS TIME. THEY DO NOT APPEAR TO BE VERY STRONG AT THIS TIME...BUT COULD CAUSE SOME VARIABLE GUSTY WINDS. AFTER THE STORMS PASS...30-40% CHANCE FOR STORMS THIS AFTERNOON AS MENTIONED ABOVE. SAME LOW LEVEL WIND SHEAR CONCERNS AND GUSTY WINDS TOMORROW AS WELL. WIND GUSTS FROM THE SOUTHWEST ACROSS THE MAIN RUNWAYS WILL LIKELY EXCEED 30KTS AT TIMES. CARNEY && .LSX WATCHES/WARNINGS/ADVISORIES... MO...NONE. IL...NONE. && WFO LSX
