AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
930 PM CDT SAT JUL 11 2015

.UPDATE...
ISSUED AT 924 PM CDT SAT JUL 11 2015

THUNDERSTORMS CONTINUE TO SPREAD SOUTHEAST ACROSS THE FORECAST
AREA THIS EVENING. THE MOST WIDESPREAD CONVECTION AT THIS POINT IS
BEGINNING TO SETTLE SOUTH OF OF THE REGION, WHERE THE WARM FRONT
HAS BEEN NUDGED A BIT SOUTH DUE TO EARLIER CONVECTION ACROSS
CENTRAL ILLINOIS. EXPECT STORMS TO CONTINUE TO FIRE FOR AT LEAST
A LITTLE LONGER IN THE VICINITY OF THE FRONTAL ZONE, ALTHOUGH A
DOWNWARD TREND SHOULD BE NOTED AS INSTABILITY WANES AND AS A SHORT
WAVE THAT HELPED TO DRIVE THE STORMS PUSHES EAST OF THE AREA.

&&

.SHORT TERM...(TONIGHT)
ISSUED AT 325 PM CDT SAT JUL 11 2015

CONVECTIVE SYSTEM CONTINUES TO MARCH EAST WITH CELLS PROPAGATING
SOUTHEAST INTO A MUCH MORE UNSTABLE ATMOSPHERE ALONG THE SOUTHWEST
FLANK OF THE STORMS THIS AFTERNOON. EXPECT THE CLUSTER OF STORMS
TO PUSH EAST-SOUTHEAST AND BE BASICALLY TO OUR EAST AND SOUTH BY
02Z/9PM. THEN THE MAIN CHALLENGE WILL BE WITH ANY ADDITIONAL
DEVELOPMENT ALONG THE WARM FRONT AND ANY NEED FOR A FLASH FLOOD
WATCH FOR AT LEAST THE NORTHERN HALF OF THE FORECAST AREA. BASED
ON THE PAST FEW RUNS OF THE HRRR MODEL AND 18Z NAM...IT APPEARS
THE BULK OF THE RAINFALL WILL BE WITH THE AFTERNOON STORMS WITH
THE HI-RES/CONVECTIVE ALLOWING MODELS NOT SHOWING ANY SIGNIFICANT
DEVELOPMENT LATE THIS EVENING. HOWEVER...THE LATEST ECMWF AND TO
SOME EXTENT THE GFS DOES SHOW DEVELOPMENT LATER THIS EVENING INTO
THE OVERNIGHT HOURS ACROSS THE NORTH...IN AREAS THAT CAN NOT TAKE
ANY MORE RAINFALL (ROUGHLY NORTH OF A JACKSONVILLE TO SPRINGFIELD
TO CHAMPAIGN LINE). WILL GO AHEAD AND ISSUE A FLASH FLOOD WATCH
FOR TONIGHT INTO SUNDAY MORNING IN AREAS THAT HAVE THE LOWEST
FLASH FLOOD GUID VALUES. KNOX COUNTY HAS ALREADY RECEIVED FROM 1
TO 2 INCHES OF RAIN TODAY WITH AREAS FURTHER EAST NOW SEEING THE
RAINFALL...SO ANY ADDITIONAL RAINS ACROSS THE NORTH WILL POSE A
SIGNIFICANT FLASH FLOOD THREAT TONIGHT INTO SUNDAY MORNING.

.LONG TERM...(SUNDAY THROUGH SATURDAY)
ISSUED AT 325 PM CDT SAT JUL 11 2015

SEVERAL STORM COMPLEXES/MCS AND POSSIBLE BOW ECHO LATE SUNDAY
NIGHT AND ESPECIALLY ON MONDAY/MONDAY EVENING AS MODELS DEPICT
AN EXTREMELY UNSTABLE ATMOSPHERE IN PLACE OVER CENTRAL ILLINOIS
MONDAY AFTERNOON AND EVENING. MIXED LAYER CAPES OF 3000-3500 ON
SUNDAY ACROSS THE WEST WITH MOST OF THE AREA SEEING 4000 J/KG
MIXED LAYER CAPES MONDAY AFTERNOON AND EVENING WITH BULK SHEAR
VALUES OF 35-45KTS. EXACT TIMING AND LOCATION THIS FAR OUT TOUGH
TO PIN DOWN BUT THE POTENTIAL IS THERE FOR A SWATH OF WIDESPREAD
DAMAGING WIND GUSTS AND ISOLATED TORNADOES MONDAY AFTERNOON AND
EVENING. THE THREAT ON SUNDAY APPEARS TO BE MORE WITH DAMAGING
WIND GUSTS FROM STORM CLUSTERS THE FORM TO OUR NORTHWEST AND SWEEP
SOUTHEAST INTO THE UNSTABLE AIR MASS. MOST OF THE MEDIUM RANGE
MODELS SUGGEST THE STRONGER SHORTWAVE TO TRACK ACROSS THE GREAT
LAKES LATE MONDAY NIGHT BRINGING A COOL FRONT SOUTHEAST INTO THE
AREA TEMPORARILY PUTTING AN END TO THE THREAT FOR WIDESPREAD
RAINFALL AND SEVERE STORMS TUESDAY AFTERNOON THRU
WEDNESDAY...BEFORE ANOTHER SHORTWAVE APPROACHES THE AREA LATE WED
INTO THU ACCOMPANIED BY SCATTERED THUNDERSTORM CHANCES INTO THE
END OF THE WEEK.

ANOTHER CONCERN WILL BE WITH HEAT INDEX VALUES IN OUR WEST AND
SOUTHWEST TOMORROW AFTERNOON AND CWA WIDE ON MONDAY WHEN VALUES
WILL RANGE FROM 100-105.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING)
ISSUED AT 610 PM CDT SAT JUL 11 2015

SCATTERED THUNDERSTORMS CONTINUE TO DEVELOP JUST NORTH OF A WARM
FRONT OVER FAR SOUTHWEST ILLINOIS AND TRACK SOUTHEAST. ADDITIONAL
STORMS WERE NOTED JUST NORTH OF KBMI AND KPIA AND WERE DRIFTING
EAST AND SOUTHEAST. THE MAIN FORECAST CONCERN WILL BE COVERAGE OF
TSRA ACROSS THE TAF SITES TONIGHT AND THEIR AFFECT TO CIGS AND
VSBYS. WITH THE WARM FRONT EXPECTED TO REMAIN GENERALLY SOUTH OF
THE KBMI AND KPIA OVERNIGHT...AM LEANING TOWARDS MORE OF AN MVFR
CIG FOR KBMI WITH LOW VFR (SCT-BKN CIGS) FOR OUR SOUTHERN TAF
LOCATIONS. THE WARM FRONT IS EXPECTED TO DRIFT SLOWLY NORTH OF THE
TAF SITES BY 13-15Z SUNDAY AS A RESULT...THE BETTER THREAT FOR
CONVECTION SHOULD BE TO OUR NORTH SO OTHER THAN VCTS WILL NOT ADD
ANY ADDL TEMPO GROUPS. WITH THE FRONT TO OUR NORTH... WILL BRING
MAINLY VFR CIGS TO THE TAF SITES FOR LATE TOMORROW MORNING INTO
THE AFTERNOON HOURS. SURFACE WINDS WILL BE SOUTHEAST AT 4 TO 9 KTS
EARLY TONIGHT WITH WINDS VARIABLE IN DIRECTION AND SPEED IN AND
NEAR ANY THUNDERSTORMS. WITH THE FRONT SHIFTING TO OUR NORTH
TOMORROW MORNING...WINDS SHOULD VEER MORE INTO A SOUTHERLY
DIRECTION AT 10 TO 15 KTS.
