.AVIATION...

1800 UTC TAFS...SHOWERS AND THUNDERSTORMS HAVE BEGUN TO DEVELOP
AND INCREASE IN COVERAGE OVER THE PAST HOUR OR TWO AS PREVIOUSLY
ANTICIPATED. COVERAGE STILL IS TOO WIDESPREAD TO PIN DOWN EXACT
ARRIVAL TIMES...AND TERMINALS LIKELY WILL SEE MULTIPLE ROUNDS OF
ACTIVITY. ESTIMATED VISIBILITY REDUCTIONS ARE BASED ON EXPECTATION
OF BRIEF HEAVY RAINFALL. WIND SPEEDS AND DIRECTION WILL NOT VARY
MUCH THIS AFTERNOON WITH A STRONG SURFACE LOW MOVING FROM THE
DAKOTAS INTO MANITOBA THROUGH THE PERIOD AND A LARGE AREA OF HIGH
PRESSURE PARKED OVER THE SOUTHEASTERN UNITED STATES.  NEW TORNADO
WATCH COVERING THE WHOLE AREA IS BEING DISCUSSED WITH SPC AT THIS
MOMENT.

LENNING

.MARINE...
230 PM CDT

SIMILAR THINKING SINCE THE EARLIER DISCUSSION FROM MID-MORNING.
HAVE BEEN MONITORING WINDS FOR POSSIBILITY OF A WARNING FOR GALES
THIS AFTERNOON.  STILL EXPECTING GUSTS TO BE NEAR CRITERIA FOR A
FEW HOURS THIS AFTERNOON...ESPECIALLY FOR TALLER VESSELS.
SUSTAINED WINDS HAVE BEEN A FEW KNOTS BELOW. OTHER QUESTION HAS
BEEN WAVE HEIGHTS. EARLIER SOUTHEAST WINDS ACROSS THE NORTHERN
LAKE HAVE TURNED SOUTH AS ANTICIPATED...AND A LONG SOUTHERLY TO
SOUTHWESTERLY FETCH HAS SET UP THIS AFTERNOON. THE MODERATING
INFLUENCE HAS BEEN STABILITY IN THE BOUNDARY LAYER WITH WARM AIR
TEMPERATURES OVER THE FAIRLY COLD LAKE. OUR WAVE MODEL CONTINUES
TO GENERATE 4 TO 6 FEET AT THIS TIME...WHICH ALSO WILL BE CLOSELY
MONITORED THROUGH THE AFTERNOON. WE MAY NEED TO NUDGE OUR WAVES UP
FOR THE NORTH HALF.  AT 2 PM CDT THE SOUTH BUOY WAS MEASURING 2 TO
3 FT WAVES AND AT THE NORTH BUOY WAVES WERE MEASURING 4 TO 5 FEET.

1140 AM CDT FRI JUN 6 2008

ILZ003>006-008-010>014-019>023-032-033-039-INZ001-002-010-011-019-

IROQUOIS-FORD-LAKE INDIANA-PORTER-NEWTON-JASPER-BENTON-
1140 AM CDT FRI JUN 6 2008 /1240 PM EDT FRI JUN 6 2008/

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

.DAY ONE...THIS AFTERNOON AND TONIGHT.

  WEATHER HAZARDS EXPECTED:

   THUNDERSTORMS...THE STRONGEST MAY PRODUCE...
   HEAVY DOWNPOURS.
   CLOUD TO GROUND LIGHTNING.
   DAMAGING WINDS IN EXCESS OF 60 MPH. QUARTER SIZE HAIL.
   ISOLATED TORNADOES.

  AREAS AFFECTED AND TIMING:

   THUNDERSTORMS WERE DEVELOPING OVER NORTHERN ILLINOIS LATE THIS
   MORNING. THUNDERSTORMS WILL LIKELY INCREASE IN COVERAGE AND
   SPREAD INTO NORTHWEST INDIANA EARLY THIS AFTERNOON.

  DISCUSSION:

  AN UNSEASONABLY STRONG UPPER LOW PRESSURE SYSTEM WILL CONTINUE
  TO LIFT NORTH ACROSS THE NORTHERN PLAINS AND UPPER MIDWEST
  THROUGH TONIGHT...WHILE A STRONG MID AND UPPER LEVEL JET STREAK
  ROTATES NORTHWARD ACROSS THE UPPER MISSISSIPPI VALLEY AND
  WESTERN GREAT LAKES REGION. THUNDERSTORMS FORMING ACROSS
  NORTHERN ILLINOIS LATE THIS MORNING WILL CONTINUE TO BECOME MORE
  NUMEROUS EARLY THIS AFTERNOON...SPREADING ACROSS THE OUTLOOK
  AREA AND INTO INDIANA. STRONG WINDS ALOFT WILL RESULT IN STORMS
  RACING NORTHEAST AT 50 TO 60 MPH...AND STRONG DEEP WIND SHEAR
  WILL ALLOW FOR ORGANIZED UPDRAFTS WITH CONVECTIVE MODE EXPECTED
  TO BE A MIXTURE OF SMALL BOWING LINE SEGMENTS AND EMBEDDED
  SUPERCELLS. THIS WILL RESULT IN SEVERE WEATHER THREATS INCLUDING
  DAMAGING WIND GUSTS IN EXCESS OF 60 MPH...LARGE HAIL...AND
  PERHAPS ISOLATED TORNADOES. THE MOST UNSTABLE CONDITIONS ARE
  EXPECTED TO DEVELOP ACROSS EASTERN ILLINOIS AND NORTHWEST
  INDIANA THIS AFTERNOON THROUGH EARLY THIS EVENING.

PORTIONS OF THE ILLINOIS RIVER WILL REMAIN IN FLOOD.

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

A PATTERN ALLOWING SOUTHERLY FLOW AT THE SURFACE WILL KEEP THE
AREA IN A VERY WARM AND HUMID AIR MASS INTO MONDAY. THIS WILL KEEP
A THUNDERSTORM THREAT OVER THE AREA MUCH OF THE WEEKEND.
HOWEVER...THE GREATEST LIKELIHOOD OF STORMS WILL BE SATURDAY
AFTERNOON AND EVENING AS STRONG LOW LEVEL FLOW REFOCUSES FROM IOWA
INTO NORTHWEST ILLINOIS...THEN LIFTS NORTHWARD ACROSS THE UPPER
MISSISSIPPI VALLEY AND WESTERN GREAT LAKES BY EARLY SUNDAY. STORMS
ARE MORE LIKELY TO BECOME ORGANIZED AND POTENTIALLY SEVERE SUNDAY
NIGHT INTO MONDAY AS THE NEXT SHORT WAVE AND ASSOCIATED SURFACE
FRONT MOVE INTO THE REGION FROM THE NORTHWEST.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON AND EVENING.
