AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
527 AM CDT WED JUN 15 2011

.DISCUSSION...
351 AM CDT

TIS THE SEASON FOR WEAKER SYNOPTIC SCALE FORCING AND MCS'S AND
MCV'S! UNFORTUNATELY THAT ALSO MEANS THE OVERALL PREDICTABILITY OF
THE WEATHER GOES DOWN.

IN THE NEAR TERM...WATCHING A CONVECTIVELY ENHANCED VORT MAX (WHICH
ACTUALLY IS SOMEWHAT RESEMBLING A TROPICAL SYSTEM WITH PSEUDO-FEEDER
BANDS AND ALL) MARCH SLOWLY EASTWARD ACROSS IOWA. PLAN TO MAKE A
LAST MINUTE CALL ON POP/WX GRIDS THIS MORNING BASED ON SATELLITE AND
RADAR TRENDS...SINCE MODELS CURRENTLY NOT HANDLING THE ONGOING MCS
ALL THAT WELL. CONVECTION WITH MORNING MCS OVER OUR CWA SHOULD BEGIN
TO WEAKEN PRIOR TO SUNRISE AS IT ENCOUNTERS DECREASING INSTABILITY.

WOULD GENERALLY EXPECT THIS MORNING MCS TO CLEAR THE CWA BY MID TO
LATE MORNING WITH A SIZABLE BREAK IN PRECIPITATION...HOWEVER WATER
VAPOR IMAGERY CONFIRMS THE PRESENCE OF ANOTHER VORT OVER NW MO THAT
MODELS ARE KEYING IN ON FOR ADDITIONAL SHOWER AND POSSIBLE
THUNDERSTORM DEVELOPMENT THIS AFTERNOON. BEST CHANCE FOR ANY
APPRECIABLE RECOVERY IN AIRMASS APPEARS TO BE OVER OUR SOUTHERN CWA
AND WITH SOME CLEARING COULD ACTUALLY SEE SOME MODEST SURFACE BASED
INSTABILITY DEVELOPING THIS AFTERNOON. STRONGER FLOW ALOFT AND
RESULTANT DEEP LAYER SHEAR SHOULD REMAIN SOUTH OF THE CWA THIS
AFTERNOON GENERALLY LIMITING THE THREAT OF ANY APPRECIABLE SEVERE
THREAT.

SHORTWAVE WILL THEN PIVOT NORTHEAST OUT OF THE AREA TONIGHT WITH NO
PARTICULARLY SIGNIFICANT SHORTWAVES EVIDENT IN MODEL GUIDANCE TO
FOCUS PRECIP THREAT TONIGHT ONCE LINGERING EVENING THREAT PULLS OUT.
ATTENTION THEN TURNS TO THURSDAY AFTERNOON AND EVENING WHEN UPPER
LOW WILL BE TRACKING INTO LOWER MICHIGAN. MODEL GUIDANCE NOT SHOWING
ANY SIGNIFICANT FEATURES ALOFT TO FOCUS STORMS THURSDAY AFTERNOON
AND EVENING...HOWEVER WITH COLD POOL ALOFT STILL NEARBY (THOUGH
MOVING OUT OF) THE AREA THURSDAY AFTERNOON AM CONCERNED THAT WITH
HEATING THERE COULD BE WIDELY SCATTERED PM STORMS DEVELOP. POTENTIAL
DOES ADMITTEDLY LOOK LOW...HOWEVER WANTED TO HAVE AT LEAST CHANCE
POPS IN GRIDS SINCE ANY STORM THAT DO DEVELOP WOULD HAVE A POTENTIAL
TO BE SEVERE GIVEN THE IMPRESSIVE DEEP LAYER SHEAR THAT DEVELOPS AS
A RESULT OF STRONG NORTHWESTERLY MID LEVEL JET ON THE BACK SIDE OF
THE DEPARTING UPPER LOW.

BEYOND THURSDAY CONFIDENCE IS EXTRAORDINARILY LOW IN WHERE THE
SURFACE FRONT AND SUBSEQUENTLY MOST FAVORABLE ZONE FOR MCS
DEVELOPMENT WILL SET-UP. TWENTY FOUR HOURS AGO IT LOOKED LIKE OUR
CWA WOULD BE WELL ENTRENCHED IN DRIER CANADIAN AIR FRIDAY...BUT NOW
MODELS HAVE FLIP-FLOPPED AROUND A BIT WITH SOME NOW INDICATING FRONT
AND CONSEQUENTLY THUNDERSTORM CHANCES COULD BE FARTHER NORTH. FOR
NOW HAVE JUST INTRODUCED SOME SLIGHT CHANCE POPS INTO THE SOUTHERN
HALF OF OUR CWA GIVEN THE MODEL INCONSISTENCIES...BUT SHOULD THE
NORTHWARD TREND CONTINUE THEN LATER SHIFTS MAY NEED TO CONSIDER MORE
AGGRESSIVE POPS.

CURRENT MODEL RUNS SUGGEST THAT THE MCS WAVE TRAIN WILL SET-UP OVER
OR NEAR THE AREA OVER THE WEEKEND. HAVE BUMPED UP POPS TO HIGH END
CHANCES FOR NOW...BUT AS CONFIDENCE GROWS IN TIMING AND TRACK OF MCS
ACTIVITY POPS MAY WELL NEED SOME UPWARD NUDGING. WHERE MCS TRAIN
DOES SET-UP WILL NEED TO MONITOR NOT ONLY FOR SOME SEVERE POTENTIAL
BUT PROBABLY MORE SIGNIFICANTLY THE THREAT OF HEAVY RAINFALL AND
FLASH FLOODING. STILL LOOKING LIKE RIDGE WILL BUCKLE OVER THE AREA
EARLY NEXT WEEK WITH AT LEAST A BRIEF SHOT OF VERY WARM (IF NOT HOT)
AND HUMID AIR BEFORE A MORE SIGNIFICANT TROUGH AND FRONT AFFECT THE
AREA.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 10Z...

  VSBYS WITH THESE STORMS.

* WIND SPEEDS AND GUSTS THROUGH THE MORNING.

* ONGOING TSRA CHANCES THROUGH THE DAY.

LENNING

//DISCUSSION...UPDATED 06Z...

PRIMARY CONCERN IS EVOLUTION OF THUNDERSTORM COMPLEX MOVING EAST
OVERNIGHT. HAVE TIMED CORE OF NORTHERN PORTION OF COMPLEX TO PUSH
INTO KRFD AREA BY AROUND 08Z...BUT THERE ARE CONVECTIVE SHOWERS
BREAKING OUT AHEAD OF THIS AND MOVING NE...WHICH IS REFLECTED IN
TAF. WANTED TO MONITOR CONVECTIVE TRENDS WITH SYSTEM BEFORE
INCLUDING PREVAILING TSRA AT KRFD. WILL AMEND AS NEEDED. TIMED
SHOWERS OUT AHEAD OF SYSTEM TO GET INTO EASTERN TERMINALS BETWEEN
830Z AND 930Z...BUT THIS IS A LOW CONFIDENCE FORECAST. QUESTION
WILL THEN BECOME WHETHER TO INCLUDE ANYTHING MORE THAN VCTS FOR
EASTERN TERMINALS AS WELL...BUT WILL ONCE AGAIN LIKE TO MONITOR
CONVECTIVE TRENDS AND AMEND ACCORDINGLY. QUESTIONS ALSO AS TO
DURATION OF SHRA/TSRA AT THE TERMINALS...WHICH IS LOW CONFIDENCE
AT THIS TIME AND WILL NEED TO BE REFINED. OTHER ISSUES ARE
SE WINDS OCCASIONALLY GUSTING UP TO AROUND 20 KT...BUT DID NOT
THINK GUSTS WOULD BE FREQUENT ENOUGH TO INCLUDE AS PREVAILING.
ONCE PRECIP STARTS TO WIND DOWN ON WEDNESDAY...POTENTIAL EXISTS
FOR CIGS AND VSBY TO REALLY COME DOWN TO MVFR OR LOWER...SO HAVE
CONTINUED TO TREND IN THIS DIRECTION. VSBY MORE LIKELY TO IMPROVE
FIRST ON WEDNESDAY NIGHT ONCE WINDS TURN TO SWLY...BUT CIGS COULD
STAY DOWN AT MVFR OR LOWER INTO THE OVERNIGHT HOURS TOMORROW
NIGHT.

//ORD AND MDW CONFIDENCE...UPDATED 10Z...

.MARINE...
500 AM CDT

WITH TROUGH OF LOW PRESSURE CENTERED OVER IOWA PUSHING EAST TOWARD
THE WESTERN GREAT LAKES...INCREASED PRESSURE GRADIENT BROUGHT
STRONGER SOUTHEAST WINDS TO THE SOUTH HALF OF THE LAKE...PRIMARILY
THE NEARSHORE WATERS. THESE STRONGER WINDS WILL CONTINUE INTO THIS
MORNING. THUS HAVE KEPT UP THE SCA FOR THE ILLINOIS NEARSHORE
NORTH OF NORTHERLY ISLAND. WINDS WILL START TO DIMINISH IN THE
AFTERNOON...SO IT IS POSSIBLE SCA MAY BE DROPPED EARLY. THE OTHER
MAIN ISSUE IN THE NEAR TERM IS THE COMPLEX OF SHOWERS AND EMBEDDED
THUNDERSTORMS PUSHING INTO THE NEARSHORE WATERS OF THE SOUTH HALF
OF THE LAKE AS OF THIS WRITING. THE PRIMARY THREAT WILL BE FOR
OCCASIONAL CLOUD TO WATER LIGHTNING STRIKES. AFTER THIS SYSTEM
MOVES EAST BY THE LATE MORNING...THE CHANCES FOR SHOWERS AND
THUNDERSTORMS WILL DIMINISH. MUCH LIGHTER WINDS WILL RETURN TO THE
LAKE LATE TODAY AND CONTINUE THROUGH FRIDAY AS THE TROUGH OF
LOW PRESSURE WEAKENS AND DRIFTS EAST AND A WEAK RIDGE OF HIGH
PRESSURE BUILDS ACROSS THE REGION BY FRIDAY. THE RIDGE WILL START
TO SHIFT EAST ON SATURDAY...WITH A TROUGH OF LOW PRESSURE SLOWLY
APPROACHING FROM THE PLAINS ON SUNDAY...BUT WINDS WILL REMAIN
RELATIVELY LIGHT. IN TERMS OF SENSIBLE WEATHER...THERE IS A
CHANCE FOR SHOWERS AND THUNDERSTORMS OVER THE LAKE ON THURSDAY
AND AGAIN ON SATURDAY AND SUNDAY.

458 AM CDT WED JUN 15 2011 /558 AM EDT WED JUN 15 2011/

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

.DAY ONE...TODAY AND TONIGHT.

  WEATHER HAZARDS EXPECTED:

  THUNDERSTORMS...SOME MAY PRODUCE:
    TORRENTIAL DOWNPOURS CAPABLE OF PRODUCING FLASH FLOODING.
    PEA SIZE HAIL.
    WIND GUSTS OVER 40 MPH.
    FREQUENT LIGHTNING.

  AREAS AFFECTED AND TIMING:

  THUNDERSTORMS CAPABLE OF PRODUCING TORRENTIAL RAINFALL AND
  LOCALIZED FLOODING ARE LIKELY THIS MORNING...ESPECIALLY BEFORE 9
  AM. THERE IS A CHANCE FOR ADDITIONAL THUNDERSTORMS LATE THIS
  AFTERNOON AND EARLY THIS EVENING...ESPECIALLY SOUTH OF
  INTERSTATE 80.

  DISCUSSION:

A LARGE CLUSTER OF SHOWERS AND THUNDERSTORMS WILL CONTINUE TO
MOVE ACROSS NORTHERN ILLINOIS THIS MORNING. THE PRIMARY THREAT
FROM THESE STORMS WILL LIKELY BE LOCALLY HEAVY RAINFALL TOTALS...
WHICH COULD RESULT IN SOME LOCALIZED FLOODING. THE THUNDERSTORMS
WILL MOVE OUT OF THE AREA DURING THE EARLY TO MID MORNING HOURS.

ADDITIONAL THUNDERSTORMS ARE POSSIBLE LATE THIS AFTERNOON INTO
THIS EVENING AS ANOTHER UPPER LEVEL DISTURBANCE MOVES ACROSS THE
AREA. WHILE AN ISOLATED SEVERE THUNDERSTORM CANNOT BE RULED OUT
SOUTH OF THE KANKAKEE RIVER...THE THREAT APPEARS TO BE QUITE LOW.

PORTIONS OF THE KANKAKEE RIVER IN NORTHWEST INDIANA AND ILLINOIS
RIVER IN LA SALLE COUNTY WILL REMAIN IN FLOOD.

THERE IS AN INCREASED RISK FOR RIP CURRENTS ALONG THE ILLINOIS
LAKE MICHIGAN SHORE TODAY.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.

THERE IS A CHANCE THAT WIDELY SCATTERED THUNDERSTORMS COULD
DEVELOP THURSDAY AFTERNOON AND EVENING. WHILE THE THREAT OF
THUNDERSTORM DEVELOPMENT APPEARS LOW...IF STORMS DO DEVELOP THEY
WOULD BE CAPABLE OF PRODUCING LARGE HAIL AND POSSIBLY LOCALLY
DAMAGING WINDS.

A FRONTAL BOUNDARY IS FORECAST TO WAVER AROUND THE REGION FRIDAY
THROUGH THE UPCOMING WEEKEND BRINGING PERIODIC CHANCES FOR
THUNDERSTORMS...WITH SOME POTENTIAL FOR SEVERE WEATHER. IT IS TOO
EARLY TO PREDICT THE TRACK OF THUNDERSTORM CLUSTERS THIS
WEEKEND...HOWEVER THERE DOES APPEAR TO BE SOME POTENTIAL FOR
REPEATED BOUTS OF THUNDERSTORMS PRODUCING HEAVY...AND POTENTIALLY
FLOODING RAINFALL TOTALS OVER PORTIONS OF THE OUTLOOK AREA.

PORTIONS OF THE KANKAKEE RIVER IN NORTHWEST INDIANA AND ILLINOIS
RIVER IN LA SALLE COUNTY WILL REMAIN IN FLOOD. IN ADDITION...HEAVY
RAINFALL OVER THE NEXT SEVERAL DAYS COULD LEAD TO RISES AND
POTENTIAL FLOODING ALONG OTHER AREA RIVERS AND STREAMS.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS ARE ENCOURAGED TO REPORT HEAVY RAINFALL TOTALS TO THE
NATIONAL WEATHER SERVICE CHICAGO.
