Damaging Wind in Illinois, July 14, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
340 AM CDT FRI JUL 14 2006

.DISCUSSION...

MAIN CONCERNS FOR THIS FORECAST ARE POPS TODAY AND THEN
TEMPERATURES/HEAT INDICES FOR THE WEEKEND AND BEYOND.

A CONVECTIVE COMPLEX THAT MOVED SOUTHEAST THROUGH MUCH OF NORTHERN
MISSOURI YESTERDAY EVENING HAS MOSTLY DIED OUT EARLY THIS MORNING AS
IT APPROACHED THE QUAD STATE.  A FEW SHOWERS AND STORMS HAVE
DEVELOPED NEAR THE REMNANT OUTFLOW BOUNDARY IN AREAS GENERALLY WEST
OF A CARBONDALE TO MT VERNON ILLINOIS LINE.  OTHERWISE...SATELLITE
INDICATES RAPID CLEARING OF CONVECTIVE DEBRIS OVER EASTERN MISSOURI
AND WESTERN ILLINOIS.

A SECOND CONVECTIVE COMPLEX IS DIVING SOUTHWARD INTO 30-40KT LOW
LEVEL JET OVER SOUTHEAST KANSAS.  WOULD EXPECT THIS ACTIVITY TO
CONTINUE SOUTH AND NOT EFFECT THE QUAD STATE THIS MORNING.  PROFILER
DATA INDICATE A MID-LEVEL DISTURBANCE ACROSS NORTHERN MISSOURI IN
THE WAKE OF THE DEAD MCS...AND ANOTHER ONE OVER CENTRAL/EASTERN
KANSAS.

ALTHOUGH NEITHER THE 00Z GFS NOR THE NAM HAD A GOOD HANDLE ON THE
EARLIER CONVECTION OVER MISSOURI...THEY BOTH BRING MID-LEVEL
DISTURBANCES EAST SOUTHEAST THROUGH MUCH OF THE AREA TODAY.  GIVEN
THE CLEARING TREND UPSTREAM...THERE SHOULD BE PLENTY OF INSOLATION
ACROSS THE AREA.  THIS COUPLED WITH THE PLENTIFUL LOW LEVEL MOISTURE
OVER THE REGION...SHOULD CREATE GOOD INSTABILITY THIS
AFTERNOON...ALONG WITH HEAT INDICES IN THE 100 TO 105 DEGREE RANGE.
THEREFORE...WOULD EXPECT TO SEE GOOD COVERAGE OF CONVECTION
TODAY...WITH BEST COVERAGE NORTH NEAREST THE MID-LEVEL DISTURBANCE.
WILL POST LIKELIES NORTH WITH CHANCES SOUTH...AND LEAST CHANCES IN
WESTERN PORTIONS OF SOUTHEAST MISSOURI. WILL KEEP CHANCE POPS IN
MAINLY FOR THIS EVENING...AS THE ACTIVITY MOVES OUT OF THE AREA TO
THE SOUTHEAST.

MID-LEVEL WINDS MAY CRANK UP TO 30-35KTS THIS AFTERNOON IN THE
NORTH...SO THERE WILL BE SOME POTENTIAL FOR STORM ORGANIZATION UP
THERE...WITH A MINOR THREAT OF DAMAGING WINDS AND LARGE HAIL.
FURTHER SOUTH INSTABILITY MAY LEAD TO A FEW BRIEF...PULSY
SEVERE STORMS...WITH HAIL AND WIND THREATS.  PRECIPITABLE WATERS IN
THE GFS ARE FORECAST AT 2+ INCHES FOR THIS AFTERNOON...SO LOCALLY
HEAVY RAINFALL WILL BE A PROBLEM AGAIN TODAY AS WELL.

THE 00Z GFS CONTINUES THE TREND OF PUSHING TODAYS SYSTEM THROUGH THE
REGION BY 12Z SATURDAY...AND BUILDING THE UPPER RIDGE INTO THE AREA
FOR THE FORESEEABLE FUTURE.  THIS WILL LEAD TO A PROLONGED PERIOD OF
HOT AND DRY CONDITIONS THROUGH THE WEEKEND AND MUCH OF NEXT WEEK.
AS THE UPPER RIDGE BUILDS...MID-LEVEL TEMPERATURES WILL WARM
FIRST...BUT THERE WILL BE LITTLE WARMING IN THE LOW LEVELS.  THE GFS
WOULD INDICATE TEMPERATURES IN THE LOWER 90S EAST TO MIDDLE 90S WEST
FOR THE NEXT SEVERAL DAYS...WITH THE WARMEST DAY ON TUESDAY...WHEN
MIDDLE AND UPPER 90S MAY OCCUR.

THE PROBLEM IS IN HOW FAST WE WILL MIX OUT THE LOW LEVEL MOISTURE.
SUSPECT THAT AFTERNOON DEWPOINTS WILL BE IN THE MIDDLE 70S TODAY AND
SATURDAY...BUT AS THE PRECIPITATION SHUTS OFF...THESE READINGS
SHOULD COME DOWN TO NEAR 70 FOR SUNDAY AND BEYOND.  THIS IS HANDLED
WELL BY THE 00Z MAV GUIDANCE...SO RAN WITH IT FOR THE GRIDDED
DEWPOINT FORECASTS.  THIS LEADS TO HEAT INDICES IN THE 100-105
DEGREE RANGE MOST AREAS TODAY AND SATURDAY...AND AGAIN THROUGH MUCH
OF NEXT WEEK.  WILL CONTINUE TO RUN A HEADLINE FOR HEAT
INDICES...BUT FORECAST LEVELS DO NOT SUPPORT ISSUANCE OF AN ADVISORY
AT THIS TIME.

AS FOR SHORT TERM TEMPERATURES...GENERALLY STAYED WITHIN RANGE OF
AVAILABLE GUIDANCE FOR LOWS...BUT UNDERCUT CONSENSUS GUIDANCE A FEW
DEGREES FOR HIGHS SATURDAY INTO MONDAY...AS THE LOW LEVEL
TEMPERATURE FORECAST IN THE GFS DOES NOT SUPPORT THE GUIDANCE
LEVELS.  THIS IS FURTHER SUPPORTED BY THE FACT THAT THE HIGHS THE
LAST SEVERAL DAYS AT KPAH HAVE BEEN CONSISTENTLY A FEW DEGREES BELOW
GUIDANCE.
