AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1124 AM CDT FRI MAY 15 2009

.DISCUSSION...
1120 AM CDT

SEVERAL CLUSTERS OF SHOWERS AND EMBEDDED THUNDER CONTINUE TO
AFFECT NORTHERN ILLINOIS AND NORTHWEST INDIANA THIS MORNING. THE
SURFACE WARM FRONT IS STILL WELL TO THE SOUTH ACROSS SOUTH CENTRAL
ILLINOIS. MAIN AREA OF INSTABILITY IS STILL SUPPRESSED WELL TO THE
SOUTH CLOSER TO THE THE LOW LEVEL WARM FRONT. SFC PRESSURE FALLS
HAVE BEEN STRENGTHENING ACROSS SOUTHEAST NEBRASKA INTO NORTHEAST
KANSAS AND EXPECTING THIS SURFACE WAVE TO TRACK INTO NORTH CENTRAL
ILLINOIS LATER THIS EVENING. AS LOW LEVEL HEIGHTS CONTINUE TO
FALL...EXPECTING LOW LEVEL JET TO STRENGTHEN AND MORE RAPIDLY
ACCELERATE WARM FRONT NORTHWARD LATE THIS AFTERNOON INTO EARLY
THIS EVENING. HAVE SOME CONCERN RUC/NAM MAY BE BRINGING WARM FRONT
NORTHWARD A LITTLE TOO FAST GIVEN CURRENT CONVECTION...BUT WILL
NEED TO BE WATCHED LATER THIS AFTERNOON. GREATEST THREAT OF SEVERE
WEATHER STILL APPEARS TO BE ACROSS SOUTHERN PORTIONS OF THE
FORECAST AREA WHERE INCREASING NEAR SFC BASED INSTABILITY IS
EXPECTED TO DEVELOP LATE THIS AFTERNOON EARLY THIS EVENING. SOME
BACKING OF LOW LEVEL FLOW AND ENHANCED LOW LEVEL SRH IS POSSIBLE
WITH THE WARM FRONT ACROSS SOUTHERN PORTIONS OF THE FORECAST AREA
EARLY THIS EVENING...SO STILL HAVE SOME CONCERN FOR ISOLATED
TORNADIC ACTIVITY SOUTH OF INTERSTATE 80 THIS EVENING. ANOTHER
CONCERN TODAY IS POTENTIAL FOR FLASH FLOODING. AREAS ALONG AND
SOUTH OF INTERSTATE 80 CORRIDOR MAY PICK UP 1 TO 1.5 INCHES OF
RAIN THIS AFTERNOON FOLLOWED BY ARRIVAL OF COLD FRONT TONIGHT.
FRONTAL CONVERGENCE ALONG THIS COLD FRONT IS RATHER IMPRESSIVE AND
HEAVY RAIN CONCERN WILL PERSIST THROUGH TONIGHT. LOCALIZED AREAS
WILL LIKELY EXPERIENCE 3+ INCHES OF RAIN BEFORE EVENT IS OVER LATE
TONIGHT AND WILL MAINTAIN FLASH FLOOD WATCH HEADLINE THROUGH LATE
TONIGHT. UPDATED ZONES HAVE BEEN SENT.

.PREV DISCUSSION...
343 AM CDT

MAIN FOCUS OF THE FORECAST THIS MORNING IS ON THE NEXT 24 HOURS AS
ANOTHER STRONG PACIFIC SHORTWAVE BARREL ITS WAY ACROSS THE
NORTHERN TIER OF STATES.

WARM FRONT CURRENTLY STRETCHES FROM NORTHERN KS EAST TO THE LOWER
OHIO VALLEY. STRONG LOW LEVEL JET ASSOCIATED THETA-E ADVECTION HAS
HELPED SUPPORT THE DEVELOPMENT OF SHOWERS/THUNDERSTORMS OVER
SOUTHERN IA AND NE KS. FIRST AREA OF CONVECTIVE DEVELOPMENT OVER
IA EARLIER THURSDAY EVENING HAS FORMED INTO A SMALL MCS WHICH HAS
BEEN TRACKING STEADILY EAST TOWARD THE CWA...HOWEVER A DRIER MORE
STABLE AIRMASS IS IN PLACE OVER N IL AND WOULD EXPECT
PRECIPITATION TO GENERALLY DECREASE IN COVERAGE AND INTENSITY AS
IT TRACKS INTO THE LESS FAVORABLE ENVIRONMENT OVER THE AREA.

NUMERICAL GUIDANCE IS IN GOOD AGREEMENT ON KEEPING STRONGEST
LOW LEVEL MOISTURE CONVERGENCE OVER NE KS INTO S IA AND N MO
THROUGH THIS MORNING INTO THE EARLY AFTERNOON. GIVEN THIS WOULD
EXPECT THE BREEDING GROUND FOR OUR PRECIPITATION TODAY TO REMAIN
IN THAT AREA WITH PRECIP SPILLING EASTWARD INTO CWA. WITH BETTER
MOISTURE AND INSTABILITY CONFINED TO AREAS WELL SOUTHWEST AND
SOUTH OF THE AREA...WOULD ALSO THINK THAT THE BETTER CHANCES FOR
HEAVY RAINFALL WOULD REMAIN SOUTHWEST OF THE CWA TODAY. HAVE
BACKED OFF TO JUST A CHC OF THUNDERSTORMS IN THE GRIDS TODAY GIVEN
THE ANTICIPATED WEAKER INSTABILITY AND WILL PUSH BACK THE START
TIME OF THE FFA A FEW HOURS WITH MORNING UPDATE TO FOLLOW
SHORTLY.

WARM FRONT IS EXPECTED TO BEGIN ACCELERATING NORTHWARD THIS
AFTERNOON AND EVENING AS UPPER TROUGH AMPLIFIES OVER THE NORTHERN
PLAINS. AS WARMER AND MORE HUMID AIRMASS SPREADS NORTH...THE
ATMOSPHERE SHOULD BEGIN TO DESTABILIZE MORE OVER OUR CWA THIS
EVENING. WITH ARRIVAL OF STRONGER SYNOPTIC SCALE FORCING AS WELL
AS MOISTURE AND INSTABILITY...POTENTIAL FOR MORE SIGNIFICANT
CONVECTION AND POSSIBLY LOCALLY HEAVY RAINFALL WILL INCREASE THIS
EVENING. GIVEN VERY STRONG DEEP AND PARTICULARLY LOW LEVEL SHEAR
PROFILES...CANNOT RULE OUT SEVERE WEATHER ALONG AND SOUTH OF THE
WARM FRONT WHERE CONVECTION WILL HAVE THE OPPORTUNITY TO BECOME
SURFACE BASED. PRECIPITATION DURING THE DAY TODAY SHOULD KEEP
LAPSE RATES FROM GETTING ALL THAT STEEP WHICH SHOULD ALSO SERVE TO
KEEP INSTABILITY MORE IN CHECK...WITH PRIMARY THREAT BEING LOCALLY
DAMAGING WINDS AND POSSIBLY A SHORT-LIVED TORNADO. TOUGH TO SAY
HOW FAR NORTH THE WARM FRONT WILL MAKE IT THIS EVENING...BUT WITH
SEVERE THREAT LIKELY TO BE CONFINED TO THE WARM SECTOR...IT WOULD
STAND TO REASON THAT THE HIGHEST SEVERE THREAT WILL RESIDE OVER
OUR SOUTHERN CWA WHERE POTENTIAL OF MAKING IT INTO THE WARM SECTOR
IS GREATEST.

STRONG COLD FRONT SWEEPS ACROSS THE CWA LATER TONIGHT SHUTTING OFF
PRECIP AND HERALDING THE ARRIVAL OF A MUCH COOLER AND DRIER
AIRMASS. EVEN THOUGH SUNSHINE IS LIKELY TO BECOME PRETTY PREVALENT
BY SATURDAY AFTERNOON...GUSTY NORTHWEST WINDS WILL ADD A BIT OF A
NIP TO THE AIR.

SURFACE HIGH PRESSURE WILL BEGIN BUILDING EASTWARD INTO THE MID
MISSISSIPPI VALLEY REGION SATURDAY NIGHT. AS IT APPROACHES THE
GRADIENT WILL QUICKLY SLACKEN OFF AND SURFACE WILL LIKELY
DECOUPLE. GIVEN THE CLEAR SKIES AND REASONABLY GOOD RADIATIONAL
COOLING SET UP...WORRIED THAT SOME AREAS COULD DIP INTO THE MID
30S BY SUNDAY MORNING WITH THE POTENTIAL FOR SOME FROST. HAVE
INTRODUCED FROST INTO THE GRIDS AND WILL HIGHLIGHT THE POTENTIAL
IN THE HWO THIS MORNING.

SURFACE HIGH SCOOTS EAST SUNDAY WITH A SLIGHT MODERATION IN TEMPS
EXPECTED AWAY FROM THE LAKE...WHERE HEALTHY LAKE BREEZE SHOULD PUT
A CAP ON TEMPS. GRADIENT SHOULD SUPPORT STRONGER SOUTHERLY FLOW
WITH QUICKLY INCREASING THICKNESSES BY MONDAY...BOTH OF WHICH WILL
SUPPORT A PRETTY DRAMATIC WARM UP TO NEAR 70F BY MONDAY AFTERNOON.
MEDIUM RANGE MODELS IN PRETTY GOOD AGREEMENT ON BACK-DOORING A
FRONT THROUGH THE AREA BRINGING MUCH COOLER TEMPS FOR TUESDAY.
HAVE STARTED TO TREND HIGHS DOWN ON TUESDAY BUT IF FRONTAL TIMING
AND POSITIONING REMAINS CONSISTENT THEN HIGHS WILL LIKELY NEED TO
BE LOWERED MORE IN LATER FORECASTS.

.AVIATION...
622 AM CDT

1200 UTC TAFS...MAIN FOCUS OVER THE BEGINNING PORTION OF THE TAF
PERIOD RESIDES WITH THE OFF AND ON CHANCES FOR LIGHT RAIN AS THE
INITIAL BATCH OF RAIN MOVES INTO THE REGION. WITH A FAIRLY
SIGNIFICANT POCKET OF LOW LEVEL DRY AIR IN PLACE...EXPECT FOR IT
TO BE TOUGH FOR ANY OF THIS RAIN TO CAUSE ANY DROPS TO MVFR
CIGS/VIS ACROSS THE TERMINALS THIS MORNING. HOWEVER...THESE
SCATTERED SHOWERS ARE EXPECTED TO PERSIST OFF AND ON THIS MORNING
WHICH SHOULD BE ENOUGH TO WET THE RUNWAYS. LIGHT AND VARIABLE
WINDS ARE EXPECTED TO GO MORE SOUTHEAST AS THE GRADIENT PICKS UP
WITH LOW PRESSURE BUILDING ACROSS THE PLAINS.

CONFIDENCE IN THE FORECAST DWINDLES THIS AFTERNOON AS THE WARM
FRONT IS ANTICIPATED TO START MOVING BACK TO THE NORTH...BRINGING
THE MORE MOIST AND UNSTABLE AIR MASS ALONG WITH IT. WILL LIKELY
CONTINUE TO SEE THE OFF AND ON SHOWERS INTO THE AFTERNOON NORTH OF
THE FRONT...BUT IF THIS FRONT CAN MAKE IT NORTH OF THE TAF SITES
THERE WILL BE A BETTER CHANCE FOR STORMS TO AFFECT THESE LOCALES.
HAVENT HIT THE FORECAST TOO HARD AT THIS POINT BUT BEST CURRENT
TIMING APPEARS TO BE THIS EVENING OUT AHEAD OF THE COLD FRONT THAT
COMES BARRELING THROUGH HERE OVERNIGHT. OUR BEST CHANCES FOR ANY
MVFR/IFR CIGS/VIS WILL COME ALONG WITH THE STORMS AS WELL WITH THE
LOW CIGS LIKELY PERSISTING OVERNIGHT INTO EARLY SATURDAY MORNING.
WINDS WILL COME AROUND FROM THE SOUTHEAST TO THE WEST/NORTHWEST
BEHIND THE FRONT AND BECOME MUCH GUSTIER UP TO AROUND 25KTS.

EXPECT VFR CONDITIONS THROUGH THE MORNING WITH MVFR TO IFR
CONDITIONS POSSIBLE TONIGHT.

.MARINE...
159 AM CDT

WEAK SOUTHEASTERLY WINDS ACROSS THE LAKE WILL GRADUALLY PICK UP
TODAY AS A LOW PRESSURE SYSTEM DEEPENS ACROSS THE NORTHERN PLAINS
AND MOVES NORTHEAST INTO CANADA WHILE DRAGGING A COLD FRONT ALONG
WITH IT. AS THIS FRONT PASSES OFF TO THE EAST...COLDER AIR WILL
RUSH IN BEHIND IT WHICH WILL HELP TO BRING WEST TO NORTHWEST WINDS
UP TO AROUND 30KTS ACROSS THE LAKE. WITH LAND TEMPERATURES QUICKLY
RISING ABOVE THE LAKE WATER TEMPS...WILL LIKELY SEE A SHALLOW
STABLE MARINE LAYER FORM DESPITE BEING IN A COLD AIR ADVECTION
REGIME. WINDS WILL DIMINISH ON SUNDAY AS A RIDGE OF HIGH PRESSURE
MOVES INTO THE REGION.

1109 AM CDT FRI MAY 15 2009 /1209 PM EDT FRI MAY 15 2009/

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.

.DAY ONE...TODAY AND TONIGHT.

  WEATHER HAZARDS EXPECTED:

  HEAVY RAINFALL AND LOCALIZED FLASH FLOODING.
  THUNDERSTORMS...SOME MAY PRODUCE:
  HAIL TO THE SIZE OF QUARTERS.
  HEAVY RAIN.
  DAMAGING WINDS IN EXCESS OF 60 MPH.
  AND POSSIBLY A TORNADO.

  AREAS AFFECTED AND TIMING:

  WIDESPREAD SHOWERS AND SOME EMBEDDED THUNDERSTORMS WILL CONTINUE
  ACROSS THE NORTHERN ILLINOIS AND NORTHWEST INDIANA THIS
  AFTERNOON. THE POTENTIAL FOR SOME SEVERE THUNDERSTORMS WILL BE
  LATE THIS AFTERNOON INTO THIS EVENING INTO THE EARLY PORTIONS OF
  THE OVERNIGHT HOURS. THE THREAT FOR HEAVY RAINFALL WILL PERSIST
  FROM THIS AFTERNOON THROUGH AFTER MIDNIGHT.

  DISCUSSION:

  WIDESPREAD SHOWERS AND SCATTERED THUNDERSTORMS WILL PERSIST
  THROUGH THE AFTERNOON AS A WARM FRONT OVER SOUTHERN ILLINOIS
  LIFTS SLOWLY NORTHWARD. INITIALLY...INSTABILITY OVER THE REGION
  IS FORECAST TO BE WEAK AND THUS ONLY SCATTERED
  THUNDERSTORMS...WITH LITTLE OR NO THREAT OF SEVERE WEATHER...ARE
  EXPECTED THROUGH MID AFTERNOON.

  BY LATE AFTERNOON OR THIS EVENING...THE WARM FRONT IS EXPECTED
  TO MOVE INTO NORTHERN ILLINOIS AND NORTHWEST INDIANA WITH A
  WARMER...MORE HUMID...AND UNSTABLE AIRMASS SPREADING NORTH AS
  WELL. AS THIS OCCURS...THE THREAT OF HEAVY RAINFALL...LOCALIZED
  FLASH FLOODING...AND SEVERE THUNDERSTORMS WILL INCREASE. THE
  PRIMARY THREAT FROM ANY SEVERE THUNDERSTORMS THAT DO AFFECT THE
  REGION TONIGHT WILL BE DAMAGING WINDS...THOUGH AN ISOLATED
  TORNADO CANNOT BE RULED OUT GIVEN THE VERY STRONG WIND FIELDS
  ABOVE THE GROUND. THE GREATEST THREAT OF SEVERE THUNDERSTORMS
  WILL BE SOUTH OF INTERSTATE 80...WHERE THE CHANCES ARE HIGHER
  THAT THE WARM...MOIST...AND UNSTABLE AIRMASS WILL SPREAD
  NORTHWARD INTO THIS EVENING.

  FINALLY...PORTIONS OF THE KANKAKEE...VERMILLION...AND ILLINOIS
  RIVERS WILL REMAIN FLOODED.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.

  THERE IS A CHANCE FOR SOME FROST LATE SATURDAY NIGHT AND EARLY
  SUNDAY MORNING...ESPECIALLY OVER THE NORTHERN AND WESTERN
  CHICAGO SUBURBS WEST INTO NORTH CENTRAL ILLINOIS.

  PORTIONS OF THE ILLINOIS...VERMILION...AND KANKAKEE RIVERS WILL
  REMAIN IN FLOOD. ADDITIONAL RIVER FLOODING IS POSSIBLE ON SOME
  OTHER MAIN STEM RIVERS IF HEAVY RAINFALL MATERIALIZES AS
  FORECAST TODAY INTO TONIGHT.

  THERE IS ALSO A CHANCE OF THUNDERSTORMS TUESDAY INTO WEDNESDAY
  OF NEXT WEEK.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED LATE THIS AFTERNOON INTO TONIGHT.
