.DISCUSSION...
315 PM CDT

AN ACTIVE PATTERN WILL BE IN PLACE THROUGH THE UPCOMING WEEKEND
PROVIDING NUMEROUS OPPORTUNITIES FOR AT LEAST CHANCES FOR SHOWERS
AND STORMS BUT IN GENERAL FEATURES DRIVING CONVECTION ARE RELATIVELY
SUBTLE AT THIS POINT. EARLY AFTERNOON WATER VAPOR IMAGERY SHOWS A
FAIRLY SHARP UPPER TROUGH OVER SOUTHERN SASKATCHEWAN AND MANITOBA
WITH SEVERAL LESS FOCUSED TROUGHS ASSOCIATED WITH IT. ONE TROUGH IS
ORIENTED NORTH-SOUTH AND IS MOVING INTO MINNESOTA/IOWA WITH ANOTHER
MOVING  SOUTHWARD INTO THE NORTHERN PLAINS. ANOTHER WAVE IS NOTED
MOVING EASTWARD ACROSS KANSAS AND OKLAHOMA. WEAK RIDGING IS
POSITIONED WEST OF THE TROUGH OVER THE PACIFIC NORTHWEST WITH A MUCH
DEEPER LONGWAVE TROUGH FROM THE GULF OF ALASKA SOUTHWARD. THIS
TROUGH AS WELL AS ADDITIONAL ENERGY TRANSLATING ACROSS THE NORTHERN
PACIFIC WILL PROVIDE A STEADY STREAM OF WEAKER SHORTWAVES ACROSS THE
MIDWEST AND WESTERN GREAT LAKES THROUGH THE PERIOD. AS THE
SURFACE...WEAK LOW PRESSURE IS SPREAD FROM THE NORTHERN PLAINS AND
UPPER MISSISSIPPI RIVER VALLEY WITH A COOL FRONTAL BOUNDARY FROM
EASTERN MINNESOTA TO CENTRAL IOWA.

LATE AFTERNOON THROUGH TUESDAY...STRONG CONVECTION CONTINUES ACROSS
NORTHWEST INDIANA AND BACK INTO IROQUOIS COUNTY TO A LESSER EXTENT
AND SEEMS TO BE IN CONJUNCTION WITH THE INTERSECTION OF A VORT MAX
AND THE WESTERN FLANK OF A LARGER AREA OF INSTABILITY. THIS ACTIVITY
WILL CONTINUE TO PROGRESS NORTHEAST OVER THE NEXT 1-2 HOURS.
EXPECT SUB SEVERE WIND NOW THAT THE ACTIVITY HAS BECOME LINEAR
WITH HEAVY RAINFALL THE PRIMARY CONCERN. OTHERWISE...THE FRONT
ACROSS IOWA WILL MOVE INTO THE AREA THIS EVENING AND LOSE SOME OF
ITS FOCUS. SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BE
POSSIBLE ACROSS THE CENTRAL AND WESTERN CWA WITH THE FRONT WORKING
EASTWARD AND SOME MARGINAL INSTABILITY. SATELLITE SHOWS SOME
BUBBLING OF CU WITH WEAK RADAR RETURNS STARTING TO BETTER ORGANIZE
ACROSS THE FAR NORTHWEST. IT DOES APPEAR THAT THE BETTER FOCUS
LOOKS TO BE LATER THIS EVENING INTO THE OVERNIGHT AS THE UPPER
WAVE NOW MOVING INTO MISSOURI LIFTS NORTHEAST UP THE OHIO VALLEY.
RADAR MOSAIC SHOWS SHOWERS AND SOME OCCASIONAL EMBEDDED THUNDER
MOVING NORTHWARD ACROSS SOUTHERN MISSOURI AND ILLINOIS IN
CONJUNCTION WITH THE ABOVE. BROADER SCALE UPPER ASCENT WILL MOVE
ACROSS THE SOUTHEASTERN PART OF THE AREA AND SHOULD RESULT IN AN
INCREASE IN COVERAGE...MAINLY ACROSS NORTHWEST INDIANA BACK INTO
THE FAR SOUTHEAST PORTION OF THE ILLINOIS CWA. SOME OF THIS
ACTIVITY MAY LINGER INTO TUESDAY MORNING. FOG DOES NOT LOOK TO BE
AS EXTENSIVE ALONG THE LAKE SHORE AS PREVIOUS NIGHTS WITH A
PREVAILING THOUGH LIGHT WEST TO SOUTHWEST WIND BUT WILL NEED TO
MONITOR THIS CLOSELY AS THE AIRMASS WILL STILL BE MOIST AND THE
FLOW LIGHT. WILL ADD PATCHY FOG TO THE EASTERN CWA WHERE RAIN IS
OR WILL HAVE BEEN FALLING THIS EVENING AND WINDS BECOME LIGHT.
ENERGY WILL CONTINUE TO ROTATE AROUND THE BASE OF THE MAIN UPPER
LOW OVER THE UPPER MISSISSIPPI RIVER VALLEY AND EASTERN DAKOTAS
TUESDAY. A WEAK IMPULSE MAY WORK THROUGH THE FLOW NORTH OF THE
AREA DURING THE AFTERNOON BRINGING A SECONDARY SURFACE FRONT
THROUGH IN THE AFTERNOON. THE BETTER LARGER SCALE ASCENT WILL BE
NORTH OF THE AREA IN CONJUNCTION WITH THE UPPER WAVE AND RIGHT
ENTRANCE REGION OF AN ORGANIZING UPPER JET. WILL CONTINUE WITH THE
SLIGHT CHANCES ACROSS THE FAR NORTHERN PART OF THE CWA DURING THE
AFTERNOON. HIGHS SHOULD WARM INTO THE LOWER 80S FOR MOST AREAS BUT
A LAKE BREEZE BOUNDARY MAY DEVELOP AND COOL LAKESHORE AREAS DURING
THE AFTERNOON.

WEDNESDAY AND THURSDAY...THE UPPER MISSISSIPPI RIVER VALLEY UPPER
TROUGH WILL SHIFT EASTWARD WEDNESDAY AND WILL BRING A PUSH OF
MODESTLY COOLER MID LEVEL AIR TO THE WESTERN GREAT LAKES. HIGH
PRESSURE WILL BE PASSING WELL TO THE NORTH BUT PROVIDE NORTHERLY LOW
LEVEL FLOW SUPPORTING AN INFLUX OF COOLER AIR OFF THE LAKE WEDNESDAY
AFTERNOON. LAKE FRONT AREAS MAY NOT REACH 70 WITH INLAND AREAS OF
THE CHICAGO METRO AND NORTHWEST INDIANA LIKELY BEING HELD TO THE
70S...WHILE LOW TO MID 80S PERSIST AROUND THE WESTERN AND SOUTHERN
PERIPHERY OF THE CWA. WITH THE NORTHEAST PUSH OFF THE LAKE AN
INSTABILITY GRADIENT/FRONTAL BOUNDARY MAY DEVELOP OUT TOWARD THE
WEST AND SOUTHWEST CWA WHICH MAY BE ENOUGH TO TRIGGER SOME ISOLATED
STORMS WEDNESDAY AFTERNOON INTO EARLY EVENING. SLIGHT RIDGING BUILDS
IN THURSDAY AND SOME GUIDANCE CONTINUES TO INDICATE THAT A STRONGER
SHORTWAVE MAY MOVE OVER OR NEAR THE LOCAL AREA LATER THURSDAY. NOT
MUCH CONFIDENCE IN THIS RIGHT NOW AND IF IT DOES NOT MATERIALIZE LOW
CONVECTIVE CHANCES WOULD CONTINUE ACROSS THE WESTERN CWA WHERE THE
INSTABILITY GRADIENT WOULD BE. WARMEST HIGHS WILL ONCE AGAIN BE WEST
AND SOUTH AND COOLEST NEAR THE LAKE.

FRIDAY THROUGH THE WEEKEND...TROUGHING WILL WORK INTO THE PACIFIC
NORTHWEST LATE IN THE WEEK WHICH WILL FORCE RIDGING TO AMPLIFY
ACROSS THE PLAINS WHICH WILL QUICKLY SHIFT OVER THE LOCAL AREA. WEAK
SHORTWAVES WILL CONTINUE TO BE POSSIBLE AS THE RIDGE BUILDS...THEN
UNDER THE WESTERN PERIPHERY OF THE RIDGE OVER THE LOCAL AREA THROUGH
THE WEEKEND. THE UPPER TROUGH LOOKS TO PROGRESS EASTWARD
SUNDAY/MONDAY CROSSING THE LOCAL AREA BRINGING A MORE FOCUSED CHANCE
FOR THUNDERSTORMS. WITH THE BUILDING RIDGE WILL COME BUILDING
HEIGHTS AND RISING TEMPS. H85 TEMPS WARM TO AROUND +18C LATE FRIDAY
INTO SATURDAY THEN MAY CREEP UP FROM THERE. HIGHS WILL WARM INTO THE
MID AND UPPER 80S WITH HUMID CONDITIONS IN PLACE...THOUGH MAY NEED
TO GO A LITTLE WARMER DEPENDING ON HOW CONVECTIVE EVOLUTION PANS
OUT.

//ORD AND MDW CONCERNS...UPDATED 20Z...

* INCREASING TSRA COVERAGE SOUTH AND EAST OF THE TERMINALS. MAINLY

THUNDERSTORM ACTIVITY HAS INCREASED ACROSS EAST CENTRAL ILLINIOS
INTO NORTHWEST INDIANA WHICH IS POSING PROBLEMS FOR INBOUND AND
OUTBOUD FLIGHTS...BUT MAINLY JUST SHOWERS WITH ISOLATED TSRA ARE
EXPECTED AROUND THE TERMINAL AREAS. CEILINGS HAD LOWERED TO MVFR
RANGE BRIEFLY BUT NOW ARE HEADING BACK UP...AND VSBY CONDITIONS
GENERALLY ARE EXPECTED TO REMAIN VFR EXCEPT FOR BRIEF PERIODS
NEAR THE HEAVIER SHOWERS. THE PEAK COVERAGE STILL IS EXPECTED
TOWARD MID TO LATE AFTERNOON...WITH THE BEST FOCUS BEGINNING TO
SHIFT EAST BY LATE EVENING. WINDS WILL REMAIN LIGHT OUT OF THE
SOUTHWEST AND THEN WEST AS A FRONT CROSSES THE AREA TONIGHT.
TUESDAY LOOKS MOSTLY DRY...WITH AN AFTERNOON LAKE BREEZE LIKELY
DEVELOPING IN THE LIGHT PRESSURE GRADIENT.

LENNING

//ORD AND MDW CONFIDENCE...UPDATED 20Z...

* MEDIUM CONFIDENCE IN SHRA COVERAGE...AND MEDIUM TO HIGH
  CONFIDENCE THAT MOST TSRA STAYS SOUTH AND EAST OF THE TERMINALS.

* MEDIUM TO HIGH CONFIDENCE IN VFR CIGS/VSBYS AWAY FROM SHOWERS.

* LOW CONFIDENCE IN WIND DIRECTION...BUT HIGHER CONFIDENCE IN SPEEDS.

LENNING

//OUTLOOK FOR ORD/MDW FOR 00Z WEDNESDAY-12Z MONDAY...UPDATED 12Z...

.MARINE...
223 PM CDT

WEBCAMS AND SATELLITE IMAGERY BOTH SUGGEST DENSE FOG IS STILL OVER
THE LAKE...SO WILL KEEP THE DENSE FOG ADVISORY GOING. THERE IS A
LITTLE CONCERN THAT THE FOG MAY CONTINUE THROUGH TONIGHT...BUT DO
NOT HAVE ENOUGH CONFIDENCE TO EXTEND THE ADVISORY NOW.

A LOW PRESSURE TROUGH AND COLD FRONT WILL MOVE OVER THE LAKE TONIGHT
AND WINDS WILL NW TO W BEHIND THE FRONT. THE BAGGY TROUGH REMAINS
OVERHEAD TOMORROW AND EXPECTING ONSHORE FLOW DEVELOP ACROSS THE LAKE
IN THE AFTERNOON.  A SECOND COLD FRONT SINKS DOWN THE LAKE IN THE
EVENING WITH WINDS BECOMING NORTH 10-15 KT BEHIND IT.  WINDS REMAIN
LIGHT OUT OF THE N TO NE AS HIGH PRESSURE BUILDS OVER THE LAKE
WEDNESDAY NIGHT.  THE LIGHT WINDS THEN VEER TO EAST THURSDAY NIGHT
AS THE HIGH SHIFTS EAST. THE GRADIENT TIGHTENS LATE THIS WEEK INTO
NEXT WEEK AHEAD OF THE NEXT STORM SYSTEM WITH SOUTH WINDS GUSTING TO
AROUND 20 KT SUNDAY.
