AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
300 PM CDT MON AUG 1 2011

.DISCUSSION...
ISSUED 300 PM CDT MON AUG 1 2011

SHORT TERM...TONIGHT THROUGH THURSDAY...
HEAT HEADLINES AND THUNDERSTORM CHANCES WITH THE NEXT FRONT WILL BE
THE MAIN FORECAST ISSUES IN THE SHORT RANGE. FIRST...THE HEAT.
TEMPERATURES OUT WEST ARE WELL ABOVE 100 OVER MANY AREAS OF
CENTRAL/WESTERN MISSOURI AND WESTWARD FROM THERE. CURRENT OBJECTIVE
ANALYSIS SUGGESTS 850MB TEMPERATURES ARE NOW 22-23 DEG C OVER THE
CENTRAL IL...AND BOTH THE NAM AND GFS PREDICT 850MB TEMPS AROUND 26
DEG TUESDAY AFTERNOON. THIS WOULD PUT TEMPERATURES AT LEAST IN THE
UPPER 90S...ALONG WITH DEWPOINTS IN THE MID 70S. POSSIBLY A FEW 100
DEGREE HIGHS IN THE SOUTHWEST. THIS YIELDS HEAT INDEX VALUES AROUND
110 FROM SPRINGFIELD TO PEORIA AND WESTWARD. SOME LOCATIONS OVER THE
SOUTHWESTERN PORTIONS OF THE FORECAST AREA HAVE A GOOD SHOT AT
SEEING NEAR 110 THIS AFTERNOON AS WELL. WILL THEREFORE UPGRADE THE
HEAT ADVISORY IN THE SOUTHWEST TO A WARNING VALID FROM NOW UNTIL 7
PM TUE. ALTHOUGH THE IL RIVER VALLEY AREAS FURTHER NORTH WILL ALSO
HAVE 110 HEAT INDICES ON TUE...THEY WILL NOT BE THAT WARM FOR MOST
OF THE AREA THIS AFTERNOON. THUS ONLY ADVISORY CRITERIA APPLIES.

CURRENT MCS OVER SOUTHEASTERN MN IS FORECAST TO MOVE SOUTHEAST BUT
STAY NORTH OF THE FORECAST AREA TONIGHT. FURTHER UPSTREAM...WATER
VAPOR SATELLITE LOOPS SHOW A VIGOROUS UPPER SHORTWAVE MOVING
NORTHEAST THROUGH NORTHERN ROCKIES. THIS SYSTEM WILL PICK UP THE
SURFACE LOW ALREADY OVER SOUTH DAKOTA AND PUSH IT EASTWARD ON
TUESDAY...WITH THE ATTENDING COLD FRONT APPROACHING THE NORTHERN
COUNTIES OF THE FORECAST AREA TOWARD 00Z WED. AIRMASS AHEAD OF THE
FRONT WILL BE HOT AND CAPPED...WITH MAIN CHANCES OF STORMS TO THE
NORTH OF THE FRONT WHERE PARCELS CAN GET MECHANICALLY LIFTED TO THE
LFC. HAVE HELD ONTO SLIGHT CHANCE POPS IN THE EXTREME NORTH FOR
TUESDAY AFTERNOON...BUT BETTER CHANCES WILL HOLD OFF UNTIL TUESDAY
NIGHT. ONCE THE FRONT CONTINUES SOUTHWARD INTO MORE OF THE AREA
TUESDAY EVENING...LOOKS LIKE A BETTER-THAN-EVEN SHOT AS STORMS NORTH
OF AN EAST-WEST LINE THROUGH BLOOMINGTON BEFORE PRECIPITATION
COVERAGE DECREASES AGAIN AFTER MIDNIGHT. WILL THEREFORE HAVE LIKELY
POPS UP THERE TUE EVENING...WITH CHANCE POPS FURTHER SOUTH. AREAS
ALONG AND SOUTH OF I-70 WILL ONLY HAVE A SLIGHT CHANCE AFTER
MIDNIGHT. ALTHOUGH THE MODELS SHOVE THE FRONT WELL SOUTH OF THE
FORECAST AREA BY NOON WEDNESDAY...WILL RETAIN CHANCE POPS IN THE
SOUTHEAST THROUGH THE AFTERNOON IN CASE THE FRONT GETS HUNG UP AS
THE UPPER SUPPORT PULLS AWAY THROUGH THE GREAT LAKES.

WEDNESDAY NIGHT AND THURSDAY LOOK PRETTY MUCH DRY AND NOT AS WARM AS
HIGH PRESSURE MOVES INTO THE MIDWEST. THE PREVIOUS GFS WAS TRYING TO
PUSH THE NEXT ROUND OF PRECIPITATION INTO WESTERN IL AS EARLY AS
LATE WEDNESDAY OR THURSDAY...BUT BELIEVE THAT THIS WAS DUE TO
EXCESSIVE GRID-SCALE FEEDBACK. THE LATEST GFS AS WELL AS THE NAM AND
ECMWF KEEPS THE HIGH PRESSURE IN CONTROL UNTIL AT LEAST THURSDAY
NIGHT. SO WILL HAVE POPS BELOW SLIGHT CHANCE UNTIL THE NEXT SYSTEM
GETS CLOSER ON FRIDAY.

LONG TERM...FRIDAY THROUGH MONDAY...
UPPER PATTERN BEGINNING FRIDAY WILL CONTINUE WITH THE BROAD UPPER
RIDGE THAT WILL EXTEND WEST-EAST ACROSS THE CENTRAL AND SOUTHERN
CONUS. AN UPPER SHORTWAVE WILL MOVE ALONG THE NORTHERN PERIPHERY OF
THE RIDGE AND BRING A COLD FRONT THROUGH THE MIDWEST ON FRIDAY. THIS
IS SIMILAR TO PREVIOUS RUNS...SO WILL CONTINUE THE POPS FOR THAT
TIMEFRAME AND CONTINUE A MENTIONABLE POP FOR THE EAST FRIDAY NIGHT.
THE MODELS ARE STILL DIFFERING SOMEWHAT ON HOW FAR SOUTH THE FRONT
WILL PENETRATE INTO THE UPPER RIDGE ON SATURDAY...SO WILL CONTINUE
WITH SLIGHT CHANCE POPS THEN. AFTER A BREAK ON SUNDAY...THE MODELS
HAVE DIFFERENT TIMING ON THE NEXT SYSTEM FOR EARLY NEXT WEEK. THE
ECMWF BRINGS A FRONT THROUGH...WHILE THE GFS HANGS ON TO THE SURFACE
RIDGE LONGER. FORECAST CONFIDENCE BECOMES LOW FOR DAYS 6 AND 7 AS
THE POTENTIAL RAIN-MAKER WILL BE SMALL SCALE AND DIFFICULT TO
RESOLVE THAT FAR AHEAD OF TIME. WILL KEEP POPS OUT OF THE GRIDS FOR
NOW UNTIL THE SITUATION BECOMES BETTER DEFINES.

ISSUED 1241 PM CDT MON AUG 1 2011

SCT TO OCCASIONALLY BKN CU FIELD WITH BASES AROUND 3500FT WILL BE
NOTED ACROSS CENTRAL ILLINOIS TODAY. THESE CLOUDS WILL QUICKLY FADE
AWAY TOWARD SUNSET...RESULTING IN CLEAR SKIES TONIGHT INTO TUESDAY
MORNING. WINDS WILL INITIALLY BE LIGHT/VARIABLE THIS AFTN...THEN
WILL BEGIN TO DEVELOP A LIGHT SOUTHERLY COMPONENT TONIGHT AS HIGH
PRESSURE DRIFTS EAST OF THE REGION. WITH CLEAR SKIES AND LIGHT WINDS
IN PLACE...PATCHY FOG WILL ONCE AGAIN DEVELOP LATE TNGT...ESPECIALLY
ACROSS EAST-CENTRAL ILLINOIS WHERE WINDS WILL BE LIGHTEST. HAVE
INCLUDED RESTRICTED VISBYS DOWN TO AROUND 4SM AT MOST SITES
OVERNIGHT...BUT HAVE GONE SLIGHTLY LOWER TO 2SM FURTHER EAST AT
KCMI. AS THE HIGH MOVES FURTHER AWAY AND A WEAK COLD FRONT
APPROACHES FROM THE NORTHWEST...SOUTHWESTERLY WINDS WILL INCREASE
INTO THE 10 TO 15KT RANGE AFTER 14Z.
