.DISCUSSION...
320 AM CDT

SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT...

TODAY AND TONIGHT...AN INVERTED TROUGH EXTENDS FROM NORTH CENTRAL
TEXAS THROUGH NORTHEASTERN ILLINOIS THIS MORNING.  THE LOWS WARM
FRONT ARCS FROM SPRINGFIELD ILLINOIS...THROUGH DELAWARE COUNTY
INDIANA. CONVECTION HAS REMAINED ACTIVE OVERNIGHT INTO EARLY THIS
MORNING...ESPECIALLY ALONG AND NORTH OF THE WARM FRONT. A LARGE
OUTFLOW BOUNDARY IS PUSHING SOUTH AWAY FROM THE MAIN LINE OF
STORMS...WITH ISOLATED STORMS BEING INITIATED BY THE OUTFLOW
BOUNDARY. THE EVENT HAS TRANSITIONED FROM SEVERE WEATHER TO A
HEAVY RAIN/FLASH FLOODING DUE TO SLOW MOVING STORMS AND PW VALUES
BETWEEN 1.5 TO 2 INCHES.

THE MAIN LOW PASSES THROUGH CENTRAL ILLINOIS TODAY AS DOES THE
MOISTURE AXIS. WINDS FLIP TO NORTHWEST BEHIND THE LOW AND PW
VALUES DROP FROM AROUND 1.5 INCHES TO 0.75 INCHES LATE TONIGHT.
GIVEN THE NOCTURNAL CONVECTION AND CLOUDY FORECAST...KEPT TEMPS A
FEW DEGREES BELOW GUIDANCE. WITH LESS HEATING TOMORROW...NOT
EXPECTING AS MUCH CAPE. THE NAM CURRENTLY FEATURES A MAX CAPE OF
AROUND 2000 J/KG EARLY ALONG AND SOUTHEAST OF THE I-55 CORRIDOR
WITH VALUES DECLINING THROUGH THE DAY. GIVEN THE NAMS WET BIAS AND
THEREFORE TYPICAL OVERESTIMATION OF CAPE...THINKING 1500 J/KG OR
LESS IS MOST LIKELY. 0-6 KM SHEAR ALSO DECREASES AS THE INVERTED
TROUGH MOVES OFF...WITH 35 KT OR LESS THROUGHOUT THE REGION.

MODEL SOUNDINGS INDICATE WARM AIR WILL BE SEEPING IN ALOFT AHEAD OF
THE WARM FRONT.  THE WARM AIR WILL CAUSE A CAP WHICH WILL FURTHER
HINDER STORM DEVELOPMENT AND THEREFORE SEVERE WEATHER. BASED ON
THE PARAMETERS...THINKING THUNDERSTORMS WILL BE MORE LIKELY
SOUTHEAST AND ALONG THE 1-55 CORRIDOR WHERE THE ENVIRONMENT IS
MORE FAVORABLE. MAIN THREAT WILL BE HEAVY RAIN...ESPECIALLY WITH
THE VERY MOIST AIR MASS OVERHEAD.

TONIGHT...WENT WITH THE QUICKER NAM AND GFS SOLUTIONS IN REGARD TO
THE NOCTURNAL PRECIP.  EXPECTING PRECIP TO MOVE QUICKLY OFF TO THE
EAST BEHIND THE DEPARTING LOW...ESPECIALLY SINCE MOISTURE WILL BE
RETREATING RAPIDLY. STAYED WITH GUIDANCE ON OVERNIGHT LOWS. THE
NIGHT WILL START CLOUDY AND CLEAR OUT LATE...LEADING TO A SLOW
DROP IN TEMPS UNTIL THE SKY CLEARS.

TUESDAY...THE DAY STARTS OFF DRY BEHIND THE FRONT AND LOW PASSAGE.
THE UPPER LEVEL TROUGH SWINGS THROUGH WISCONSIN AND NORTHERN
ILLINOIS TUESDAY AFTERNOON AND EVENING. MODELS INDICATE CONVECTION
WILL FORM TUESDAY AFTERNOON ACROSS WISCONSIN.  CAPE VALUES ARE
MEAGER AT BEST AND WITH THE TROUGH SINKING SOUTH OUT OF CANADA...AM
QUESTIONING HOW MUCH MOISTURE THE MODELS KEEP WITH THIS SYSTEM.
DOWNPLAYING THE PRECIP POTENTIAL IN THE LOT CWA...THINKING THE
MAJORITY OF PRECIP WILL DRY UP BEFORE ENTERING NORTHERN IL.  ONCE
AGAIN WENT WITH GUIDANCE FOR TEMPS...AS THE DAY WILL BEGIN SUNNY
WITH INCREASING CLOUD COVER.

BOTH THE GFS NAM...AND THE ECMWF TO A LESSER EXTENT...SUGGEST A
MCS WILL FORM TUESDAY NIGHT IN EAST CENTRAL WI AND SINK SOUTH OVER
THE LAKE. WITH ALL 3 MODELS DEPICTING A SIMILAR STORY...DECIDED TO
PUT IN SLIGHT CHANCE TO CHANCE POPS FOR TUESDAY NIGHT...HOWEVER
CONFIDENCE IS LOW REGARDING WHERE THE ACTUAL MCS WOULD FORM IF AT
ALL.

WEDNESDAY...A DRY PATTERN BEGINS ON WEDNESDAY AS HIGH PRESSURE MOVES
IN FROM THE CENTRAL PLAINS.  SLIGHTLY COOLER TEMPS EXPECTED WITH
NORTHWEST UPPER LEVEL FLOW OUT OF CANADA.

JEE

EXTENDED...THURSDAY THROUGH SUNDAY...

410 AM CDT

OVERALL...THE EXTENDED FORECAST LOOKS DRY WITH AVERAGE TEMPS. A
BROAD RIDGE SETS UP OVER THE GREAT PLAINS MID WEEK AND PASSES OVER
THE MISSISSIPPI RIVER VALLEY LATE IN THE WEEK. NEXT CHANCE OF
PRECIP ARRIVES FRIDAY NIGHT AS A SURFACE LOW PASSES NORTH OF THE
GREAT LAKES AND ITS COLD FRONT PASSES THROUGH THE AREA LATE FRIDAY
NIGHT. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO FORM ALONG THE
COLD FRONT AND PERSIST THROUGH THE EARLY PART OF SATURDAY. THE
ECMWF HAS THE BAND OF PRECIP MOVING THROUGH THE AREA FASTER THAN
THE GFS...BUT AT THIS DISTANCE...DECIDED TO KEEP PRECIP IN THE
FORECAST SPANNING BOTH FORECASTS.

FOR TEMPS...MAX TEMPS REMAIN AROUND THE CLIMATIC NORMAL...IN THE MID
60S TO LOW 70S. OVERNIGHT LOWS APPEAR TO REMAIN WELL ABOVE FREEZING
THROUGHOUT THE EXTENDED.

* RAIN THRU REST OF MORNING WITH MVFR AND TEMPO IFR.
* RATE OF IMPROVEMENT TO VFR THIS AFTERNOON.
* POSSIBLE WIND SHIFT TO OUT OF NE-ENE THIS AFTERNOON.

TRS

//DISCUSSION...UPDATED 14Z...

MID LEVEL LOW CURRENTLY MOVING E ACROSS NORTHERN IL PRODUCING -RA
OCNL RA AND ACCOMPANYING MVFR AND TEMPO IFR CONDITIONS TO REACH NE
IL AROUND 18Z AND THEN CONTINUE ACROSS FAR SOUTHERN LAKE MI AND
NORTHERN IND DURING THE REST OF THE AFTERNOON.

BACK EDGE OF -RA BASED ON BOTH MODEL FORECAST OF FEATURE POSITION AS
WELL AS STRAIGHT EXTRAPOLATION HAVE -RA ENDING CHI TERMINALS
17Z OR SO. LARGE AREA OF IFR CEILINGS ACROSS ALL BUT NW AND FAR W
CENTRAL WI EXTENDS DOWN TO E CENTRAL IA SO PREVAILING MVFR CIGS AT
17Z AND AND VFR AT 19Z MAY BE A BIT PREMATURE AND GOOD CHANCE WILL
HAVE TO DELAY FOR AT LEAST A FEW HRS.

SFC PRES FALL CENTER FOLLOWING SFC LOW OVER SOUTHERN LAKE MI WAS
OVER FAR NE IL AT 13Z AND LOCAL SFC WINDS HAD FALLEN OFF TO BLO
10KT. MAIN SFC LOW CENTERED OVER SOUTHERN IND PROGGED TO NE IND BY
18Z. NEWEST RUC13 AT NAM12 SHOW A SUBTLE SFC HI OVER FAR SOUTHERN
LAKE MI THIS AFTERNOON WITH SFC WINDS RESPONDING BY VEERING TO N
AND NE AND THUS TRENDS WILL HAVE TO BE WATCHED TO SE IF THIS
DEVELOPS... THOUGH EVEN IF IT DOES FORECAST WINDS SPEEDS ARE BLO
10 KT.

CHANCES OF TS LOW AND WILL CONT TO DECREASE TODAY AS STABLE
CONDITIONS TO ONLY BECOME MORE SO...ESPECIALLY IF LOW CLOUDS
LINGER WELL INTO THE AFTERNOON.

PREVIOUS DISCUSSION...UPDATED 12Z...

AREA OF RAIN WITH EMBEDDED THUNDERSTORMS ENTERING INTO NORTHWEST
IL HAS SLOWLY WEAKENED AND HAVE BACKED OFF THUNDER MENTION TO JUST
VCTS AS NEW DEVELOPMENT IS STILL POSSIBLE. BUT EXPECT BULK OF THE
ACTIVITY TO BE LIGHT/MODERATE RAIN THROUGH MID/LATE MORNING WITH A
FEW SHOWERS PERHAPS LINGERING INTO THE EARLY AFTERNOON.

LOW CIGS HAVE DEVELOPED BUT STILL APPEAR TO BE BOUNCING AROUND
QUITE A BIT. WITH THE SURFACE LOW NOW EAST OF CMI...WINDS HAVE
SHIFTED AROUND TO THE NORTHWEST AND THINK LIFR CIGS SHOULD LIFT
THROUGH IFR INTO LOW MVFR THIS MORNING THOUGH CONFIDENCE ON EXACT
CLOUD HEIGHTS AS WELL AS THEIR DURATION IS STILL LOW. POSSIBLE
MVFR CIGS COULD PERSIST INTO THIS AFTERNOON AND WILL NEED TO BE
MONITORED THIS MORNING.

AS NOTED...WINDS SHIFTED WESTERLY AND GUSTY IN A FEW LOCATIONS BUT
SHOULD DIMINISH OVER THE NEXT FEW HRS AS THEY TURN BACK MORE
NORTHERLY. WINDS REMAIN NORTHERLY INTO THIS AFTERNOON BUT MODELS
HINTING AT A WEAK RIDGE DEVELOPING ALONG THE WEST SIDE OF THE LAKE
BY EVENING WHICH MAY ALLOW WINDS TO SWING AROUND TO THE NORTHEAST.
NOT TOO CONFIDENT THAT WILL HAPPEN AND WHILE ITS NOT IN THE THIS
SET OF TAFS...IT REMAINS A POSSIBILITY. WINDS WILL THEN SHIFT BACK
AROUND LIGHT NORTHWESTERLY LATER THIS EVENING. CMS

//ORD AND MDW CONFIDENCE...UPDATED 14Z...

* HIGH CONFIDENCE RA PERSISTS THRU MORNING.
* HIGH CONFIDENCE MINIMAL THREAT FOR TS.
* HIGH CONFIDENCE PREVAILING LIFR AND TEMPO IFR THROUGH MORNING.
* MEDIUM CONFIDENCE IMPROVEMENT TO VFR BY MID AFTERNOON.
* HIGH CONFIDENCE WINDS REST OF A.M.
* MEDIUM CONFIDENCE WINDS P.M.

.MARINE...

317 AM...LOW PRESSURE OVER CENTRAL IL WILL LIFT NORTHEAST ACROSS
NORTHERN INDIANA TODAY REACHING LAKE ERIE TONIGHT. THERE COULD BE A
FEW HOUR PERIOD EARLY THIS MORNING WHERE WINDS OVER SOUTHERN LAKE
MICHIGAN GUST INTO THE 15-25 KT RANGE AS THE LOW APPROACHES WITH A
SOUTHEAST DIRECTION SHIFTING TO THE NORTHEAST THIS MORNING. WINDS
WILL THEN SHIFT NORTHERLY AND DIMINISH INTO THE 10-15 KT RANGE
THIS AFTERNOON. A WEAK RIDGE MAY ALLOW WINDS TO DIMINISH EVEN
FURTHER ALONG THE WESTERN SIDE OF THE LAKE. A SECOND LOW WILL MOVE
SOUTHEAST ACROSS THE NORTHERN LAKES TONIGHT AND MERGE WITH THE
FIRST LOW LIFTING NORTHEAST ACROSS THE EASTERN LAKES ON TUESDAY. A
COLD FRONT WILL THEN MOVE SOUTH ACROSS THE LAKE TUESDAY NIGHT INTO
WEDNESDAY MORNING WITH NORTHERLY WINDS POSSIBLY INCREASING TO
15-25 KT. A LARGE RIDGE OF HIGH PRESSURE WILL THEN BUILD EAST
ACROSS THE LAKES REGION WEDNESDAY NIGHT INTO THURSDAY. CMS
