Area forecast discussion, Jun 12, 5:55 PM CST, 3 hours 5 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE ST LOUIS MO 655 PM CDT SAT JUN 12 2010 .UPDATE... /655 PM CDT SAT JUN 12 2010/ SVR TSRA WATCH EXPIRING IMMINENTLY...AND THE TSRA SHOULD EXIT THE FA WITHIN AN HOUR OR SO LATER...AND STRATIFORM RAIN DISSIPATING OVER STL METRO. ONLY REAL FOCUS FOR THE NEXT FEW HRS AFTER THAT IS W-E ORIENTED QSTNRY BDRY OVER SRN MO...OTRW SHOULD SEE CLEARING AND DRY ELSEWHERE. MCS RAMPING UP TO OUR W WILL BECOME MORE OF AN INFLUENCE LATE TONIGHT. TES && .DISCUSSION... /435 PM CDT SAT JUN 12 2010/ AN MCS FROM THIS PAST MORNING MCS HAS KICKED OUT AN OUTFLOW BDRY THAT IS IN THE PROCESS OF MOVING THRU A VERY MOIST...UNSTABLE... AND WEAKLY CAPPED ATMOSPHERE. IT IS BEING FURTHER DRIVEN BY A MODERATELY STRONG VORT MAX RIPPLING THRU SRN MO...AND IS HEADING E. EXPECT MUCH OF THIS TO BE DIURNALLY DRIVEN WITH A DEFINITIVE WEAKENING TREND AS WE APPROACH SUNSET...AND MUCH OF THE FOCUS WILL BE ON THE SERN HALF OF THE FA THRU 01 OR 02Z. BEYOND THAT...IT APPEARS ANOTHER MCS WILL FORM OVER THE CNTRL PLAINS THIS EVENING AND THEN HEAD ENEWD TOWARDS NWRN MO LATE TONIGHT. THIS SHOULD EXCLUDE THE FA FROM THIS BEFORE 12Z AND ONLY WENT WITH MINIMAL CHCS FOR PCPN OVERNIGHT. WE EXPECT THE MCS TO THEN CONTINUE TO DRIVE INTO THE NWRN FA ON SUNDAY MORNING AS IT WEAKENS. HOWEVER...THE NWRN FA IS ALREADY PRETTY SATURATED FROM PREVIOUS RAINFALL AND SO THIS WILL REPRESENT A MARGINAL THREAT FOR FLASH FLOODING. HAVE PLACED LOCALLY HEAVY RAINFALL IN THE FORECAST FOR NOW FOR THIS AREA AND LET THE MID CREW GET A FINAL LOOK BEFORE PULLING THE TRIGGER ON ANY FFA. AN OUTFLOW SHOULD GET EJECTED FROM THE WEAKENING MCS ONCE AGAIN AND PLAY HAVOC WITH THE VERY MOIST...UNSTABLE...AND WEAKLY CAPPED ATMOSPHERE THAT WILL BE IN PLACE OVER MUCH OF THE FA ONCE AGAIN ON SUNDAY AFTN. WHILE MOST PLACES IN STL METRO AND SWRN IL ONLY TOPPED OUT AT 100F HEAT INDICES BRIEFLY EARLY THIS AFTN...A FEW ISOLD AREAS DID REACH 105F BRIEFLY DUE TO VERY HIGH DEWPOINTS BEFORE THEY MIXED OUT AS EXPECTED. THIS SHOULD BE VERY SIMILAR TO WHAT WILL HAPPEN AGAIN ON SUNDAY...AND GIVEN THE OVERALL SITUATION WITH RAIN...CLOUDS AND BREVITY OF HEAT DANGER...WILL FOREGO ANY HEAT HEADLINES. WHAT WE WILL THEN SEE SUNDAY NIGHT THRU EARLY MONDAY EVENING WILL BE A REPEAT OF MCS FORMATION SUNDAY NIGHT BUT A BIT FURTHER S AND THUS WILL AFFECT A GREATER PORTION OF THE FA...IF NOT BY 12Z MONDAY...MORE DEFINITELY BY MONDAY MORNING...ESPECIALLY AS SYNOPTIC CDFNT BEGINS ITS DRIVE THRU THE REGION. THIS ACTIVITY SHOULD GRADUALLY FOCUS MORE IN SRN MO/SRN IL AND AREAS FURTHER S AS PRIMARY BDRY SETTLES THERE HEADING INTO MID WEEK. FOR THE EXTENDED PERIOD (TUESDAY NIGHT - SATURDAY)...HAVE GONE PRIMARILY DRY...BUT THIS IS NOT LIKELY TO BE ENTIRELY SO. OLD FRONT TO OUR S AT THE START OF THE PERIOD WILL RIDE BACK N AGAIN AS A WRMFNT ON WEDNESDAY NIGHT AND PLACE THE FA IN A WARM SECTOR SETUP THURSDAY AND FRIDAY. PCPN CHCS THRU FRIDAY WILL BE MINIMAL. MODELS THEN BRING A CDFNT THRU FRIDAY NIGHT OR SATURDAY...AND SOME HAVE BIGGER TIMING ISSUES THAN THAT. GIVEN THE LARGE TIMING SPREAD AND HOW FAR OUT THIS IS...WILL ALLOW FOR ANOTHER LOOK AT MODELS TOMORROW BEFORE PLACING THIS CHC IN THE FORECAST. OTHERWISE... TEMPS EXPECTED TO BE AOA NORMAL THRU THE PERIOD...ESPECIALLY THURSDAY AND FRIDAY WHERE HEAT INDEX READINGS WILL ONCE AGAIN BE HITTING 100F IN AREAS...NAMELY STL CITY. TES && .AVIATION... /629 PM CDT SAT JUN 12 2010/ BROKEN LINE OF THUNDERSTORMS CONTINUES MOVING EAST-SOUTHEAST THROUGH THE AREA. HEAVY RAIN PRODUCING IFR CIGS/VSBYS IS LIKELY WITH THE STORMS...AS WELL AS WIND GUSTS IN EXCESS OF 35KTS AND SMALL HAIL. A REGION OF STRATOFORM RAIN IS LINGERING BEHIND THE STORMS WHICH HAS AREAS OF LOW MVFR CIGS AS EVIDENCED BY RECENT OBSERVATIONS FROM KJEF. THIS RAIN SHOULD LINGER ACROSS CENTRAL MISSOURI AND SOUTHWEST ILLINOIS FOR THE FIRST FEW HOURS OF THE EVENING BEFORE DISSIPATING. REMAINDER OF EVENING INTO EARLY OVERNIGHT HOURS SHOULD BE VFR...BUT LIGHT FOG WILL LIKELY DEVELOP LATE TONIGHT...ESPECIALLY IN SHELTERED AREAS. SPECIFICS FOR KSTL... OBS IN CENTRAL MO HAD CIGS BELOW 2000FT AT TIMES WITH STRATOFORM RAIN REGION...SO IT SEEMED PRUDENT TO INCLUDE THIS AT KSTL FOR AN HOUR. END OF TEMPO IS BASED ON MOVEMENT OF THE BACK EDGE OF THIS RAIN ON NWS DOPPLER RADAR. THINK MARGINAL FOG IS LIKELY TONIGHT GIVEN THE WET GROUND...LIGHT WIND AND RELATIVELY CLEAR SKY. MORE STORMS ARE POSSIBLE SUNDAY AFTERNOON AS REMNANTS OF TONIGHT'S CONVECTION OVER THE PLAINS MOVES INTO MISSOURI...BUT TIMING AND COVERAGE IS UNCERTAIN SO DID NOT INCLUDE IN THE FORECAST AT THIS TIME.
