AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
903 PM CDT SUN JUN 21 2015

.UPDATE...
ISSUED AT 900 PM CDT SUN JUN 21 2015

TREND FOR THE REST OF THE NIGHT IS FOR DRY CONDITIONS UNTIL LATE
TONIGHT. HRRR AND RAP OUTPUT BOTH SHOW INCREASING CHANCES AFTER
09Z. THERE IS SOME INDICATION OF A LINE OF SHOWERS DEVELOPING NEAR
SPI AND EXTENDING IN A NW TO SE LINE AS THEY MOVE NORTHEAST ACROSS
OUR AREA. THE SHOWERS APPEAR TO BE SPOTTY, AND MOST AREAS SHOULD
REMAIN DRY. WE REDUCED POPS THIS EVENING IN ALL AREAS, AND KEPT A
GRADUAL INCREASE OF POPS AFTER MIDNIGHT.

THE HRRR IS ADVERTISING A STRONG MCS ROLLING ACROSS NORTHERN IOWA
TONIGHT AND REACHING NORTHERN IL BETWEEN 12Z-14Z. THE RAP SHOWS
INCREASE COVERAGE OF STORMS IN OUR WESTERN CWA, WITH A WAVE
APPROACHING FROM THE NW LATE TONIGHT, BUT NOT NEARLY AS VIGOROUS
AS THE HRRR. THE HRRR TRACK SHOWS THE STRONGEST STORMS SHOULD
REMAIN NORTH OF OUR COUNTIES TOMORROW MORNING, BUT SPC HAS KEPT US
IN A MARGINAL RISK FOR SEVERE STORMS (5%) NORTH OF PEORIA.

SATELLITE IMAGES SHOW A THIN LAYER OF HIGH CLOUDS WILL LIKELY
COVER ALL BUT THE NORTHERN COUNTIES FOR MUCH OF THE NIGHT. THE
INSULATING EFFECT OF THE CLOUDS AND HIGH SURFACE DEWPOINTS SHOULD
HELP TO KEEP LOWS IN THE UPPER 60S TO LOW 70S. LIGHT FOG COULD
DEVELOP IN LOW LYING AREAS, AS SURFACE WINDS REMAIN LIGHT THE REST
OF THE NIGHT.

.SHORT TERM...(TONIGHT)
ISSUED AT 259 PM CDT SUN JUN 21 2015

MCS WITH SHOWERS AND THUNDERSTORMS OVER CENTRAL MO AND DEVELOPING
EASTWARD INTO SW HALF OF IL WITH THUNDERSTORMS AS FAR EAST AS
EASTERN SHELBY COUNTY. DIURNALLY INDUCED INSTABILITY AS CAPES
RISING INTO THE 1500-3000 J/KG RANGE AND HIGHEST OVER OVER SW CWA
AT MID AFTERNOON. CAPES RISE TO 4000 J/KG AND HIGHER OVER CENTRAL
AND WESTERN MO AND 4000-6000 J/KG FURTHER WEST OVER KS. SOME CIN
RESTRICTINGCONVECTION DEVELOPMENT OVER SOUTHEAST IL BUT THAT IS
FADING AND EXPECT SCATTERED CONVECTION TO DEVELOP THERE AS WELL
LATE THIS AFTERNOON/EARLY EVENING. AN OLD OUTFLOW BOUNDARY EXTENDS
FROM FAR NORTHERN MO INTO FAR SW IL CLOSER TO MS RIVER VALLEY.
EXPECT THE BOUNDARY TO GRADUALLY SHIFT BACK NORTHWARD LATE THIS
AFTERNOON AND INTO TONIGHT ACROSS CENTRAL AND EVENTUALLY NORTHERN
IL WITH UPPER LEVEL SHORT WAVE CURRENT TRACKING EAST SOUTHEAST
ACROSS THE NORTHERN PLAINS. HAVE LIKELY CHANCES OF SHOWERS AND
THUNDERSTORMS OVER SW CWA THIS AFTERNOON INTO EARLY EVENING AND
THEN TAPERS TO SLIGHT CHANCES FROM I-74 NE. OUR NE CWA FROM I-74
NE TO SEE THERE BEST CHANCES OF SHOWERS AND THUNDERSTORMS AFTER
SUNSET TONIGHT. SPC CONTINUES SLIGHT CHANCE OF SEVERE STORMS FROM
RUSHVILLE TO TERRE HAUTE SW REST OF THIS AFTERNOON AND INTO THIS
EVENING WHILE ENHANCED RISK IS FURTHER SW OF CWA OVER CENTRAL MO
INTO SW IL WHERE AIRMASS IS MORE UNSTABLE. LOCALLY HEAVE RAIN
POSSIBLE SW CWA AS WELL WITH PRECIPITABLE WATER VALUES RANGING
FROM 1.5-2 INCHES WHILE AROUND 2 INCHES OVER PARTS OF CENTRAL MO.
MUGGY LOWS TONIGHT IN THE LOWER 70S WITH A FEW UPPER 60S NE OF
I-74.

.LONG TERM...(MONDAY THROUGH SUNDAY)
ISSUED AT 259 PM CDT SUN JUN 21 2015

LOOKS LIKE WE WILL GET A BRIEF BREAK FROM THE CHANCE OF SHOWERS AND
STORMS MONDAY AS THE FRONTAL BOUNDARY WILL LIFT BACK NORTH DURING
THE MORNING AND THEN BE ACROSS NORTHERN IL OR EVEN SOUTHERN WI. BUT
WE WILL KEEP A SMALL CHANCE OF PCPN IN MONDAY IN THE EXTREME NORTH
PARTS OF THE CWA. UNFORTUNATELY THIS WILL NOT LAST LONG AS ANOTHER
COLD FRONT WILL DROP THROUGH THE AREA MONDAY NIGHT WITH MORE SHOWERS
AND THUNDERSTORMS. THIS FRONT WILL LIKELY NOT DROP TOO FAR AND
BECOME QUASI-STATIONARY OVER THE SOUTHERN HALF OF ILLINOIS FOR
TUESDAY AND TUESDAY NIGHT. SO PCPN CHANCES WILL CONTINUE IN THE
SOUTHEAST FOR TUE AND THEN OVER THE WHOLE AREA FOR TUE NIGHT AS
ANOTHER POSSIBLE MCS DEVELOPS WEST OF THE AREA AND ROLLS INTO IL FOR
TUE NIGHT INTO WED. ANY OUTFLOW BOUNDARY WILL BE OVER THE AREA WED
NIGHT AND THUR THUS CONTINUING THE CHANCES OF SHOWERS AND STORMS
THROUGH THUR. FOR THE REMAINDER OF THE WEEK AND INTO THE WEEKEND...A
FRONTAL BOUNDARY WILL REMAIN OVER THE AREA...WHICH WILL KEEP THE
CHANCE OF SHOWERS AND STORMS IN THE AREA THROUGH THE END OF THE WEEK
AND INTO THE WEEKEND.

TEMPS WILL BE QUITE WARM THROUGH THUR AND WITH DEWPOINTS IN THE
LOWER 70S HEAT INDEX VALUES WILL GET INTO THE 95 TO 100 RANGE ON
MONDAY AND WED. THIS WORTH NOTING...BUT NOT ENOUGH FOR A HEAT
ADVISORY. A COLD FRONT WILL SLIDE THROUGH THE AREA LATER IN THE WEEK
AND THEN SHOULD BRING COOLER TEMPS TO THE REGION FOR FRIDAY THROUGH
SUNDAY.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z MONDAY EVENING)
ISSUED AT 648 PM CDT SUN JUN 21 2015

THE FRONTAL BOUNDARY IS LOCATED ACROSS SOUTHERN IL, SOUTH OF OUR
COUNTIES. NEARLY ALL THE CONVECTION HAS MOVED EAST OF OUR FORECAST
AREA, WITH A GROUP OF CELLS WEST OF PEORIA AND ANOTHER DOWN NEAR

SHOWERS OR STORMS THE REST OF THE NIGHT. WILL KEEP THE TAFS ALL
DRY FOR NOW, WILL FOLLOWS HRRR MODEL TRENDS.

LOW TO MID CLOUDS HAVE THINNED OUT WITH THE DEPARTURE OF PRECIP
FROM NEAR THE TAF SITES. WILL KEEP SKIES VFR OVER THE NEXT 24
HOURS.
