...THUNDERSTORMS LIKELY TO BRING HEAVY RAINFALL THIS AFTERNOON
INTO TONIGHT...

.SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS
NORTHWEST AND NORTH CENTRAL ILLINOIS THIS AFTERNOON AHEAD OF AN
APPROACHING LOW PRESSURE SYSTEM. THE SHOWERS AND THUNDERSTORMS
WILL LIKELY PERSIST INTO MONDAY MORNING WHILE SLOWLY EVOLVING EAST.
A VERY MOIST AIR MASS WILL BE IN PLACE AND THE ATMOSPHERE WILL BE
SUPPORTIVE OF STORMS WHICH MAY REPEATEDLY TRACK ACROSS THE SAME
AREAS. AS A RESULT THERE IS THE POTENTIAL FOR COMMUNITIES 
GENERALLY ALONG AND NORTH OF A LINE FROM STREATOR TO PEOTONE TO
HEBRON...INCLUDING THE CHICAGOLAND AREA...TO RECEIVE BETWEEN 1 TO
POSSIBLY 3 INCHES OF RAINFALL BY MONDAY MORNING. THIS MUCH
RAINFALL...ESPECIALLY DURING THE HEAVIEST RATES...MAY LEAD TO
FLASH FLOODING.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
351 AM CDT SUN MAY 6 2012

.DISCUSSION...

351 AM...PRIMARY FORECAST CONCERN AND CHALLENGE IS CONVECTION OVER
THE NEXT 36 HRS AND POTENTIAL FOR HEAVY RAIN AND FLASH FLOODING
TONIGHT.

LARGE LINE OF TS EXTENDING FROM NORTHWEST WI BACK THROUGH NEBRASKA
WILL CONTINUE EAST THIS MORNING. STILL SOMEWHAT UNCERTAIN IF THIS
ACTIVITY WILL REACH THE NORTH/NORTHWEST CWA LATER THIS MORNING...
AS ITS DECAYING. NOT EXPECTING ANYTHING HEAVY BUT IT COULD IMPACT
TEMP TRENDS AND PERHAPS HIGH TEMPS ACROSS THE NORTH. ANY LEFTOVER
OUTFLOWS COULD BECOME THE FOCUS FOR ADDITIONAL DEVELOPMENT THIS
AFTERNOON AS COULD A WARM FRONT LIFTING NORTH ACROSS THE SOUTHERN
CWA THIS AFTERNOON INTO THIS EVENING. WITH DEWPOINTS INCREASING
INTO THE MID/UPPER 60S SOUTH OF THE FRONT COMBINED WITH TEMPS INTO
THE 80S...INSTABILITY WILL BE HIGH WITH CAPE VALUES PERHAPS
3000-4000 J/KG. SEVERE THREAT WILL LIKELY BE HIGHEST ALONG AND
SOUTH OF THE FRONT BUT DIFFICULT TO FIND A TRIGGER TO AID
CONVECTIVE DEVELOPMENT. WHILE THE THREAT OF A TORNADO IS RATHER
MINIMAL...CERTAINLY POSSIBLE WITH ANY STORMS THAT DEVELOP
ALONG/NEAR THE WARM FRONT.

AS THE LOW APPROACHES AND DAYTIME HEATING WANES...EXPECT THE MAIN
THREAT TO TRANSITION TO HEAVY RAIN DURING THE EVENING AND INTO
THE OVERNIGHT HOURS. WHILE CONFIDENCE REGARDING WHERE AND ALSO
WHEN THUNDERSTORMS WILL DEVELOP TONIGHT IS STILL NOT THAT HIGH...
AS THE SURFACE LOW APPROACHES AND PASSES RIGHT OVER THE CWA BY
EARLY MONDAY MORNING...STEERING WINDS BECOME RATHER LIGHT LENDING
SUPPORT FOR SLOW MOVING AND POSSIBLE BACKING BUILDING CONVECTION.
ADDED TO THAT...PRECIPITABLE WATER VALUES RANGING FROM 1.5 TO AS
HIGH AS 1.8 INCHES. WHILE THERE CONTINUE TO BE SHIFTS...MODELS
HAVE SHOWN SOME CONSENSUS WITH THE AREA OF GREATEST CONCERN FOR
HEAVY RAIN ACROSS NORTHERN ILLINOIS INTO FAR SOUTHERN WISCONSIN.
WHILE ONLY A FEW AREAS SAW HEAVY RAIN FRIDAY MORNING...
SPECIFICALLY NORTHERN/SOUTHERN COOK COUNTY AND SOUTH/CENTRAL
LASALLE COUNTY...THE POTENTIAL FOR A PROLONGED PERIOD OF HEAVY
RAIN WHICH COULD CAUSE FLASH FLOODING IS HIGH ENOUGH TO ISSUE A
FLASH FLOOD WATCH FOR THE NORTHERN TWO THIRDS OF THE CWA.

AS NOTED ABOVE...CONFIDENCE REGARDING TIMING IS SOMEWHAT LOW AS
WELL AND THINK THE HEAVY RAIN MAY END UP BEING MAINLY OVERNIGHT...
PERHAPS AFTER 04Z OR 05Z. THE LATER IT STARTS...THE LONGER IT MAY
PERSIST INTO MONDAY MORNING. AS THE LOW SHIFTS EAST ON MONDAY...
PRECIP WILL END FROM WEST TO EAST. AS FOR STORM TOTAL QPF
AMOUNTS...CURRENT GRIDS HAVE 2 TO 2.5 INCHES ALONG AND NORTH OF
I-80 BUT ITS IMPORTANT TO REMEMBER THESE AMOUNTS MAY FLUCTUATE
NORTH OR SOUTH WITH SOME AREAS IN THE WATCH POSSIBLY RECEIVING
FAR LESS.

THIS LOW SLOWS AND ABSORBS A SECOND LOW MOVING SOUTHEAST OUT OF
CANADA MONDAY NIGHT INTO TUESDAY SETTING UP NORTHWEST FLOW ACROSS
THE LAKES AND AS THIS LOW FINALLY SHIFTS EAST TUESDAY NIGHT INTO
WEDNESDAY...A COLD FRONT WILL MOVE SOUTH ACROSS THE REGION
WEDNESDAY BRINGING BOTH A CHANCE OF SHOWERS AS WELL AS ANOTHER
PERIOD OF BELOW NORMAL TEMPS FOR MID WEEK. CMS

&&

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 06Z...

* IFR CIG TRENDS OVERNIGHT.

* POTENTIAL FOR MVFR/IFR FOG DEVELOPMENT OVERNIGHT.

* NORTH TO NORTHEAST WINDS BECOMING MORE EASTERLY OVERNIGHT.

* CHANCES FOR SHRA/TSRA FROM LATE SUNDAY AFTERNOON THROUGH THE
  EVENING...WITH SHRA AND POSSIBLY TSRA CONTINUING INTO MONDAY
  MORNING.

MDB

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

ANOTHER TOUGH CIG/VSBY FORECAST TONIGHT. SURFACE OBS AND SATELLITE
IMAGERY SHOW IFR/LIFR STRATUS DECK ACROSS NORTHERN ILLINOIS
RETREATING NORTHWARD. THIS IS INTERESTING BECAUSE LOW LEVEL WIND
PROFILES REMAIN NORTH OR NORTHEASTERLY SO IT APPEARS THAT SOME
MINIMAL DRYING IS TAKING PACE HELPING TO SCATTER CIGS. NOT QUITE
CLEAR ON WHETHER THIS TREND WILL REVERSE OR NOT SO WILL NEED TO
MONITOR BUT AREAS FURTHER NORTH INCLUDING RFD SHOULD REMAIN
IFR/LIFR THROUGH THE NIGHT. ORD/DPA WILL BE MORE DIFFICULT TO
FIGURE OUT AS THEY ARE ON THE FRINGE OF THE CLOUDS...BUT T APPEARS
THAT SCATTERING WILL OCCUR AT THESE SITES. WHERE CLOUDS HANG ON
THEN VSBY SHOULD STAY CLOSE TO CURRENT VALUES BUT CLEAR AREAS MAY
SEE A REDUCTION IN VSBY YET TONIGHT AND THIS MAY LEAD TO A RETURN
OF THE LOW CLOUD DECK. WINDS REMAIN VARIABLE BETWEEN NORTH AND
EAST AND THE TENDENCY WILL BE TO GO TO A STEADIER EAST THEN EAST-
SOUTHEAST DIRECTION THROUGH THE NIGHT.

LOW PRESSURE WILL APPROACH SUNDAY TURNING WINDS SOUTHEAST DURING
THE AFTERNOON. IFR/MVFR CIGS THAT ARE STILL AROUND SHOULD QUICKLY
LIFT/SCATTER DURING THE MORNING BUT A LOWER END VFR DECK MAY BE IN
PLACE THROUGH THE AFTERNOON. CHANCES FOR SHOWERS AND THUNDERSTORMS
WILL SPREAD EASTWARD ACROSS THE TERMINALS FROM LATE SUNDAY
AFTERNOON INTO SUNDAY EVENING. THE SET UP IS SUCH THAT THERE MAY
BE A PROLONGED PERIOD OF SHRA/TSRA AT THE TERMINALS DURING THE
EVENING AND OVERNIGHT HOURS.

HIGH PRESSURE CONTINUES TO STRETCH FROM WESTERN HUDSON BAY SOUTHEAST
INTO NORTHERN NEW ENGLAND. LOW PRESSURE CENTERED OVER THE OK/TX
PANHANDLE REGION WILL DRIFT EASTWARD TODAY WITH AN INVERTED TROUGH
STRETCHING TO ITS NORTH. THIS TROUGH AXIS THEN ARCS NORTHWESTWARD TO
A DEVELOPING LOW OVER SOUTHERN SASKATCHEWAN. EASTERLY WINDS WILL
CONTINUE THIS MORNING BEFORE A WARM FRONTAL BOUNDARY SETS UP ACROSS
THE CENTRAL PART OF THE LAKE. THIS WILL ALLOW WINDS ACROSS THE NORTH
TO TURN NORTHEASTERLY AND TO A MORE SOUTHEASTERLY DIRECTION ACROSS
THE SOUTHERN PART OF THE LAKE. THE SURFACE LOW WILL WEAKEN AS IT
CROSSES THE SOUTHERN PART OF THE LAKE MONDAY MORNING. WINDS WILL
TURN NORTHERLY ACROSS THE ENTIRE LAKE AS THE LOW MOVES TO THE EAST
MONDAY AFTERNOON. THE SASKATCHEWAN LOW WILL THEN CROSS THE LAKE AS
MORE OF AN OPEN TROUGH THAN A CLOSED LOW. FAIRLY STRONG HIGH
PRESSURE WILL FOLLOW IN ITS WAKE LEADING TO A PERIOD OF ELEVATED
WINDS WEDNESDAY THANKS TO AN INCREASED PRESSURE GRADIENT. THE HIGH
WILL THEN SLOWLY MOVE EAST ACROSS THE REGION THROUGH THE END OF THE
WEEK KEEPING A NORTHERLY WIND THROUGH THURSDAY WITH A FLIP TO A
SOUTHERLY DIRECTION FRIDAY. THERE IS THEN GOOD AGREEMENT ON A FRONT
CROSSING THE REGION AGAIN SATURDAY WITH ANOTHER AREA OF HIGH
