AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
317 AM CDT THU JUN 25 2015

.SHORT TERM...(TODAY)
ISSUED AT 317 AM CDT THU JUN 25 2015

07Z/2AM SURFACE ANALYSIS SHOWS LOW PRESSURE CENTERED OVER SOUTHWEST
IOWA...WITH STATIONARY FRONTAL BOUNDARY ARCING SOUTHEASTWARD INTO
WESTERN KENTUCKY.  VWP NETWORK SHOWS 40-45KT 850MB JET ORIENTED FROM
EASTERN KANSAS ACROSS MISSOURI...FEEDING THE ONGOING MCS ACROSS
EASTERN IOWA INTO CENTRAL ILLINOIS.  LOW-LEVEL AIRMASS REMAINS QUITE
STABLE DUE TO WIDESPREAD SHOWERS/THUNDER EARLIER IN THE DAY KEEPING
THE FRONT/OUTFLOW BOUNDARY SUPPRESSED WELL TO THE SOUTH.  AS A
RESULT...STORMS WILL REMAIN ELEVATED AS THEY SPREAD E/SE ACROSS THE
KILX CWA EARLY THIS MORNING.  MAIN THREATS WILL BE PROLIFIC
LIGHTNING AND LOCALIZED FLASH FLOODING...WITH PERHAPS AN ISOLATED
WIND GUST OF 30-50 MPH WITH THE STRONGEST STORMS.  WILL CARRY LIKELY
TO CATEGORICAL POPS THROUGH MID-MORNING AS THE MCS MOVES ACROSS THE
AREA.  AFTER THAT...PRECIP CHANCES WILL DECREASE SUBSTANTIALLY FROM
MIDDAY THROUGH THE AFTERNOON HOURS.  BIG QUESTION WILL BE WHETHER OR
NOT ATMOSPHERE WILL DESTABILIZE SUFFICIENTLY IN THE WAKE OF THE
MORNING CONVECTION TO PRODUCE ANOTHER ROUND OF THUNDERSTORMS LATER
TODAY.  MOST MODEL GUIDANCE SUPPORTS AT LEAST SCATTERED
ACTIVITY...ALTHOUGH THINK AREAL COVERAGE WILL REMAIN LIMITED DUE TO
THE RELATIVELY STABLE AIRMASS.  WILL THEREFORE ONLY MENTION CHANCE
POPS THIS AFTERNOON...WITH HIGH TEMPERATURES RANGING FROM THE LOWER
80S FAR NORTH AROUND GALESBURG AND LACON TO THE LOWER 90S SOUTH OF
I-70.

&&

.LONG TERM...(TONIGHT THROUGH WEDNESDAY)
ISSUED AT 317 AM CDT THU JUN 25 2015

A RELATIVE LULL IN PRECIP CHANCES WILL CONTINUE THROUGH TONIGHT...AS
SHORT-WAVE RIDGING DEVELOPS BEHIND THE DEPARTING WAVE TODAY. THE
NEXT UPSTREAM SHORT-WAVE CURRENTLY EVIDENT ON WATER VAPOR IMAGERY
OVER THE NORTHERN ROCKIES WILL TRACK SOUTHEASTWARD TONIGHT INTO
FRIDAY...INTERACTING WITH A COLD FRONT TO PRODUCE ANOTHER ROUND OF
SHOWERS AND THUNDERSTORMS.  THIS FEATURE HAS BEEN DELAYED SLIGHTLY
FROM PREVIOUS FORECASTS AND IS NOW EXPECTED TO TRACK ALONG THE
BOUNDARY DURING THE DAY FRIDAY...SUPPORTING LIKELY POPS ACROSS ALL
BUT THE FAR NORTHERN KILX CWA.  LOCALLY HEAVY RAINFALL WILL BE
POSSIBLE THROUGH FRIDAY EVENING BEFORE THE WAVE DEPARTS...SO A FLASH
FLOOD WATCH MAY NEED TO BE CONSIDERED BY LATER SHIFTS.  ALL MODEL
SOLUTIONS SHOW PRECIP EXITING ILLINOIS BY DAWN SATURDAY...SO HAVE
LOWERED POPS CONSIDERABLY AFTER MIDNIGHT.

THE REMAINDER OF THE EXTENDED WILL BE DOMINATED BY A DEEP UPPER-
LEVEL TROUGH OVER THE MIDWEST/GREAT LAKES...RESULTING IN BELOW
NORMAL TEMPERATURES THROUGH THE PERIOD.  DRY WEATHER WILL BE THE
RULE FOR BOTH SATURDAY AND SUNDAY...WITH HIGHS ONLY IN THE UPPER
70S.  MODELS CONTINUE TO ADVERTISE A FAIRLY POTENT WAVE DIGGING
SOUTHEASTWARD INTO THE BASE OF THE TROUGH EARLY NEXT WEEK...WHICH
WILL BRING THE NEXT CHANCE FOR SHOWERS INTO THE AREA.  GFS IS THE
FASTEST WITH THIS FEATURE...POTENTIALLY BRINGING PRECIP INTO THE
WESTERN CWA AS EARLY AS SUNDAY AFTERNOON.  MEANWHILE...ECMWF
REMAINS ABOUT 12 HOURS SLOWER...FOCUSING RAIN CHANCES SUNDAY NIGHT
INTO MONDAY.  AT THIS POINT...WILL STICK WITH THE MORE CONSISTENT
ECMWF.  AFTER THAT...A SERIES OF VERY WEAK DISTURBANCE WILL PASS
THROUGH THE REGION AS THE TROUGH REMAINS IN PLACE...HOWEVER NONE
OF THEM APPEAR STRONG ENOUGH TO WARRANT A MENTIONABLE POP.  WILL
THEREFORE GO WITH A DRY FORECAST WITH TEMPS REMAINING IN THE UPPER
70S AND LOWER 80S THROUGH THURSDAY.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 1216 AM CDT THU JUN 25 2015

A THUNDERSTORM COMPLEX WILL SPREAD EASTWARD ACROSS CENTRAL IL TAF
SITES FROM 06-08Z BRINGING PERIODS OF IFR/MVFR CIGS/VSBYS AS WELL
AS POTENTIAL FOR GUSTY AND VARIABLE WINDS...WHICH COULD BECOME IN
EXCESS OF 40 KTS BRIEFLY. CURRENT TRENDS FAVOR A FEW HOURS OF
POTENTIALLY INTENSE THUNDERSTORMS FROM AROUND 06-12Z FOR WHICH
TEMPO GROUPS WITH GUSTY/VARIABLE WINDS AND IFR VSBYS HAVE BEEN
INCLUDED IN 06Z TAFS. AFTERWARD...MVFR CEILINGS AND SCT SHOWERS
WILL CONTINUE UNTIL TOWARD 00Z FRIDAY AS A COLD FRONT SETLLING
SOUTHEAST THROUGH THE AREA WILL BEGINS TO BRING DECREASING SHOWER
ACTIVITY AND LOW CLOUD COVER. WINDS E-SE 5-10 KTS VEERING TO SW
OVERNIGHT...THEN N AFTER COLD FRONT AFTER AROUND 00Z.

.ILX WATCHES/WARNINGS/ADVISORIES...
