AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
242 PM CDT FRI AUG 13 2010
.DISCUSSION...
/134 PM CDT FRI AUG 13 2010/
TONIGHT THROUGH SUNDAY...THE FIRST OF TWO SHORTWAVE TROFS TO
AFFECT THE REGION WAS LOCATED ACROSS NE/KS AT 19Z. THE SECOND
SHORTWAVE TROF WAS LOCATED FARTHER UPSTREAM OVER MT/ID. THESE
SHORTWAVES WILL PROVIDE UPPER LEVEL FORCING TO SUPPORT
THUNDERSTORMS THIS AFTERNOON/TONIGHT AND AGAIN ON
SATURDAY/SATURDAY NIGHT AS A COLD FRONT MOVES INTO THE AREA.
GIVEN AMPLE INSTABILITY AND LIMITED WIND SHEAR...A FEW STORMS MAY
BE SEVERE AND CAPABLE OF PRODUCING DAMAGING WIND GUSTS AND LARGE HAIL.
ONGOING STORMS IN NWRN MO ARE EXPECTED TO DEVELOP INTO A QLCS AND
PROGRESS ACROSS PARTS OF NORTHERN MISSOURI AND WEST CENTRAL
ILLINOIS EARLY THIS EVENING. PW VALUES AROUND 2 INCHES /99TH
PERCENTILE FOR SWRN MO IN AUG/ AND DEEP WARM CLOUD LAYERS SUGGEST
HEAVY RAINFALL MAY ALSO BECOME A CONCERN.
CDFNT WILL BE MOVING THROUGH THE CWA ON SATURDAY AS LARGE SCALE
LIFT INCREASES AHEAD OF THE SECOND SHORTWAVE TROF. HOT AND HUMID
AIR MASS AHEAD OF THE FRONT ON SATURDAY WILL SUPPORT THUNDERSTORMS
ACROSS THE AREA. A FEW OF THE STORMS ON SATURDAY COULD BE SEVERE
AND CAPABLE OF PRODUCING DAMAGING WIND GUSTS.
H85 FNT LAGS THE SFC FNT AND WILL BE ACROSS THE CWA ON SUN AFTN.
H85 MCONV MAY SUPPORT ISO/SCT TSRA ON SUN AFTN AND THUS MAINTAINED
GOING SCHC POPS ACROSS THE SRN HALF OF THE CWA. COOLER AND LESS
HUMID AIR FILTERS IN TO THE REGION BEHIND THE CDFNT...PROVIDING A
MUCH NEEDED BREAK FROM THE ONGOING OPPRESSIVE HEAT.
MON THROUGH FRI...PATTERN TRANSITION LEAVES THE CWA IN WEAK NW FLOW
ALOFT BY MON/TUE AS A LONGWAVE TROF SETTLES OVER SERN CANADA AND THE
NERN US WHILE A SFC HIGH SLIDES SEWD OUT OF THE NRN PLAINS. MUCH NEEDED
BREAK FROM THE HEAT SHOULD LAST FOR AT LEAST A FEW DAYS AS H85
TEMPERATURES FALL TO 14 TO 16 DEG C BY TUE AND DRIER AIR FILTERS
INTO THE REGION. SHORTWAVES MOVING THROUGH THE FLOW WILL PROBABLY
SUPPORT TSRA ON SOME DAYS NEXT WEEK BUT I HAVE LOW CONFIDENCE IN
THE TIMING OF THESE IMPULSES...ESPECIALLY SINCE THE MODELS STILL
DISAGREE ON SOME OF THE LARGE SCALE DETAILS. ECMWF/GFS/GEM
CONTINUE TO INDICATE PCPN CHCS FOR TUE THROUGH WED BUT THE
METEOROLOGICAL REASON SEEMS TO CHANGE WITH EACH RUN. YESTERDAY THE
ECMWF DEPICTED A SHORTWAVE TROF DROPPING SEWD OUT OF CANADA BUT
TODAY IT DEPICTS A SHORTWAVE MUCH FARTHER SOUTH.
SIMILARLY...YESTERDAY'S GFS DEPICTION OF A GULF COAST LOW MOVING
NWD INTO MO/IL HAS BEEN REPLACED WITH HINTS OF A WEAK SHORTWAVE IN
NEARLY ZONAL FLOW FOLLOWED BY A STRONGER VORT MAX MOVING THROUGH
SRN CANADA. GFS/ECMWF IN BROAD AGREEMENT THAT RIDGING ALOFT
RETURNS TO THE AREA FOR THU BUT THERE IS DISAGREEMENT ON THE
DURATION. FOR THESE REASONS...I HAVE LOW CONFIDENCE IN THE LAST
FEW PERIODS OF THE EXTENDED FORECAST.

.AVIATION...
/1125 AM CDT FRI AUG 13 2010/
HOT AND HUMID CONDTIONS CONTINUE WITH LIGHT SOUTH WIND. CHANCES OF
THUNDERSTORMS TO INCREASE LATE THIS AFTERNOON AND INTO THE EVENING
FROM NORTHWEST TO SOUTHEAST. LATEST SHORT RANGE MODEL GUIDANCE
WOULD SUGGEST LINE OF THUNDERSTORMS FORMING ACROSS SOUTHWEST IOWA
AND NORTHWEST MISSOURI WOULD REACH KUIN AROUND 23Z...KCOU AROUND
00Z...AND THE METRO TAF SITES AROUND 02Z. HAVE HIGHEST CONFIDENCE
AT KUIN...AND HAVE INCLUDED A TEMPO GROUP THERE. CONFIDENCE
DECREASES FURTHER SOUTH AND WILL NOWCAST THIS AFTERNOON WITH
LATEST RADAR TRENDS. ALOT OF UNCERTAINTY HEADING INTO THE
OVERNIGHT HOURS AS LOW LEVEL JET MAY CONTINUE TO FEED CONVECTION
ACROSS THE CWA.
SPECIFICS FOR KSTL...
VFR CONDITIONS TO CONTINUE THIS AFTERNOON. COULD SEE SOME ISOLATED
STORMS DEVELOP LATER THIS AFTERNOON...BUT BELIEVE THEY WILL BE
EVEN MORE ISOLATED THAN YESTERDAY. ATTENTION THEN TURNS TO THE
NORTHWEST AS ORGANIZED LINE OF CONVECTION COULD REACH KSTL THIS
EVENING. CONFIDENCE IN THIS SCENARIO IS NOT HIGH ENOUGH TO INCLUDE
A TEMPO...BUT RADAR TRENDS WILL NEED TO BE WATCHED.
