.DISCUSSION...

347 AM CDT

CONVECTIVE TRENDS TODAY/TONIGHT ARE MAIN FOCUS OF FORECAST THIS
MORNING.

SMALL ELEVATED MCS CONTINUES TO DEVELOP ACROSS NORTHERN IOWA
EARLY THIS MORNING...IN ASSOCIATION WITH MID LEVEL SHORT WAVE
NOTED IN WATER VAPOR NOW OVER NORTHWEST IA...AND IN REGION OF
THETA/E ADVECTION AND MOIST CONVERGENCE ON NOSE OF 35 KNOT 925
HPA LOW LEVEL JET PER REGIONAL WIND PROFILERS. RUC/SPC
MESOANALYSIS GRAPHICS DEPICT AN AXIS OF 500-1000 J/KG MUCAPE FROM
NORTH/CENTRAL IA EAST INTO NORTHERN IL...THOUGH INSTABILITY
DECREASES WITH EASTWARD EXTENT. RUC CONTINUES TO VEER/WEAKEN LOW
LEVEL JET THIS MORNING AS IT BENDS INTO NORTHERN IL/SOUTHERN
WI...AND WITH WEAKER INSTABILITY ACROSS AREAS EAST OF THE
MISSISSIPPI RIVER WOULD EXPECT SOME DECREASE IN INTENSITY OF
CONVECTION AS MCS PROPAGATES ACROSS NORTHERN IL EARLY THIS
MORNING. HOWEVER...WILL HAVE TO MONITOR SEVERE THREAT...AS 0-6 KM
SHEAR 50-60 KNOTS AND CELLS JUST WEST OF WATERLOO AND CEDAR RAPIDS
AREA PRESENTING STRONG BOWING SIGNATURE. APPEARS STORMS WILL ENTER
FAR WESTERN CWA AT/JUST BEFORE SUNRISE...SPREADING EAST TOWARD
CHICAGO THROUGH 7 OR 8 AM. WILL CARRY LIKELY POPS ACROSS PARTS OF
NORTH CENTRAL ILLINOIS THIS MORNING...TRAILING TO CHANCE FARTHER
EAST/SOUTH. AS OFTEN OCCURS IN THESE SETUPS...EXPECT WE MAY SEE
CONVECTION WEAKEN A BIT THROUGH MID MORNING...AFTER WHICH TIME
STORMS MAY BECOME SURFACE/NEAR SURFACE BASED WITH RENEWED
INTENSIFICATION AND EXPANSION ALONG OUTFLOW BOUNDARIES.

FROM LATE MORNING ON...MID LEVEL JET STREAK CONTINUES TO SPREAD
FROM NORTHERN PLAINS THROUGH WESTERN LAKES. WEAK SURFACE LOW
REFLECTION OF SHORT WAVE CURRENTLY OVER IOWA TO LIFT NORTHEAST
ACROSS WISCONSIN THROUGH THIS AFTERNOON...TRAILING COLD FRONT
SLOWLY ACROSS NORTHERN ILLINOIS. EXPECT THUNDERSTORMS TO INCREASE
IN COVERAGE AND INTENSITY ACROSS THE AREA ALONG AND AHEAD OF
FRONT BY THIS AFTERNOON...AND CONTINUE INTO TONIGHT AS
FRONT/OUTFLOW SAGS SOUTHEAST. LOW LEVEL MOISTURE RETURN IN WARM
SECTOR EXPECTED TO PUSH SURFACE DEW POINT TEMPS INTO LOW-MID 60S
BY AFTERNOON...WITH ATMOSPHERE BECOMING MODERATELY UNSTABLE WITH
NAM FORECAST 1000-1500 J/KG MLCAPES INDICATED ALONG WITH 40-50
KNOTS OF 0-6 KM BULK SHEAR. THIS SUGGESTS SEVERE THREAT INTO THIS
EVENING...WITH DAMAGING WINDS AND HAIL MOST PROBABLE GIVEN FAIRLY
UNIDIRECTIONAL FLOW WITH SOUTHWEST LOW LEVEL WINDS...THOUGH
OUTFLOW BOUNDARIES AND CONVECTIVELY DISTURBED BOUNDARY LAYER WIND
FIELD COULD INCREASE LOW LEVEL SHEAR AND CANT RULE OUT ISOLATED
TORNADO THREAT. SPC HAS UPGRADED LARGE AREA INCLUDING WFO CHICAGO
CWA TO MODERATE RISK MAINLY FOR DAMAGING WIND POTENTIAL WITH
STORMS TODAY AND THIS EVENING.

COLD FRONT SLOWLY SAGS SOUTHEAST OF FORECAST AREA OVERNIGHT...
ALLOWING SHOWERS AND STORMS TO END FROM THE NORTHWEST TONIGHT.
ADVERTISED PATTERN SHIFT IN PROGRESS AS UPPER TROUGH OVER ONTARIO
AMPLIFIES AND MOVES SOUTHEAST...SETTING UP LONG WAVE TROUGH OVER
EASTERN CONUS FOR MUCH OF COMING WEEK. THIS RESULTS IN DRY/COOLER
CONDITIONS THROUGH THE WEEK...THOUGH A FEW WAVES ROTATING THROUGH
WEST SIDE OF UPPER TROUGH ESPECIALLY TUESDAY MAY ALLOW ENOUGH
COOLING ALOFT FOR ISOLATED OR SCATTERED INSTABILITY
SHOWERS/THUNDERSTORMS EVEN WEST OF LAKE MICHIGAN. CONFIDENCE IN
THIS RATHER LOW AT THIS TIME HOWEVER...SO HAVE MAINTAINED DRY
FORECAST FOR NOW...THOUGH HAVE NUDGED TEMPS DOWN JUST A BIT
ESPECIALLY MONDAY WITH NORTH/NORTHWEST WINDS AND FAIRLY IMPRESSIVE
LOW LEVEL COLD ADVECTION. AFTER LOW/MID 80S TODAY...HIGHS
GENERALLY 70-75 MONDAY GRADUALLY MODERATING BACK TO AROUND 80 BY
NEXT WEEKEND.

1142 AM CDT SUN JUN 15 2008 /1242 PM EDT SUN JUN 15 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...SOME OF WHICH MAY PRODUCE:

WIND GUSTS TO 75 MPH.
HAIL TO THE SIZE OF QUARTERS.
ISOLATED TORNADOES.
BRIEF HEAVY DOWNPOURS.

AREAS AFFECTED AND TIMING:

THUNDERSTORMS ARE POSSIBLE ACROSS THE ENTIRE AREA. THE BEST
CHANCE FOR THUNDERSTORMS WILL BE FROM MID AFTERNOON INTO THE LATE
EVENING HOURS. THUNDERSTORMS WILL MOVE SOUTHEAST...ENDING FIRST
ACROSS NORTHWEST ILLINOIS...THEN ENDING LAST ACROSS NORTHWEST
INDIANA...AROUND OR AFTER MIDNIGHT.

DISCUSSION:

THUNDERSTORMS OVER SOUTH CENTRAL IOWA AND NORTHERN MISSOURI ARE
EXPECTED TO MOVE EAST ACROSS WESTERN AND CENTRAL ILLINOIS THIS
AFTERNOON...MAINLY AFFECTING AREAS SOUTH OF INTERSTATE 80.
ADDITIONAL THUNDERSTORMS MAY DEVELOP ALONG AND AHEAD OF A COLD
FRONT AS IT MOVES ACROSS NORTHERN ILLINOIS LATE THIS AFTERNOON AND
THIS EVENING. THESE STORMS WILL AFFECT THE ENTIRE AREA.

AS DAYTIME TEMPERATURES WARM... THE ATMOSPHERE WILL BECOME
MODERATELY UNSTABLE. WITH A FAIRLY STRONG UPPER LEVEL JET STREAM
SHIFTING ACROSS THE UPPER MIDWEST...THE RESULTING COMBINATION OF
INSTABILITY AND DEEP VERTICAL WIND SHEAR WILL ALLOW SOME
THUNDERSTORMS TO BECOME SEVERE THIS AFTERNOON. WHILE WIND PROFILES
ARE EXPECTED TO BE LARGELY UNIDIRECTIONAL ACROSS THE REGION... AND
SUGGEST THAT DAMAGING WINDS IN EXCESS OF 70 MPH AND LARGE HAIL
WILL BE THE PRIMARY SEVERE WEATHER THREATS... THE THREAT OF AN
ISOLATED TORNADO CAN NOT BE RULED OUT. IN ADDITION...BRIEF HEAVY
DOWNPOURS WILL BE POSSIBLE WITH THE THUNDERSTORMS. THE GREATEST
THREAT OF SEVERE WEATHER WILL LIKELY SHIFT SOUTH OF THE INTERSTATE
80 CORRIDOR THIS EVENING...AS A COLD FRONT PUSHES SLOWLY SOUTHEAST
ACROSS THE OUTLOOK AREA. THUNDERSTORMS SHOULD END BY MIDNIGHT
NORTH OF INTERSTATE 80...AND DURING THE OVERNIGHT HOURS ACROSS
PORTIONS OF THE OUTLOOK AREA SOUTH OF INTERSTATE 80.

PORTIONS OF THE PECATONICA...ROCK...FOX AND DES PLAINES RIVERS
WILL REMAIN IN FLOOD.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.

PORTIONS OF THE PECATONICA...ROCK...FOX AND DES PLAINES RIVERS
