AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
512 PM CDT MON MAY 7 2012

.DISCUSSION...
306 PM CDT

VISIBLE IMAGERY THIS AFTERNOON CONTINUES TO DEPICT A CHANNEL OF
CLOUDS ALONG THE WEAK FRONTAL BOUNDARY SLOWLY PUSHING EAST ACROSS
THE GREAT LAKES REGION...STRETCHING FROM LOWER MICHIGAN SOUTHWEST
THROUGH CENTRAL ILLINOIS AND EASTERN MISSOURI. REGIONAL DOPPLER
RADAR MOSAIC HAS INDICATED A FEW THUNDERSTORMS HAVE DEVELOPED ACROSS
CENTRAL/SOUTHERN PORTIONS OF INDIANA. THE PUSH OF DRY AIR HAS BEEN
LACKING...AND NOT ANTICIPATING ANY CHANGE TO THIS THROUGH THE
EVENING. TEMPS ACROSS NORTHERN IL/NORTHWEST IN HAVE REMAINED NEARLY
STATIONARY IN THE MID 60S THIS AFTERNOON GIVEN THE ABUNDANCE OF
SOLAR SHIELDING. FURTHER UPSTREAM ACROSS IOWA AND WESTERN WISC...DRY
AIR HAS ARRIVED AND CLEARED OUT MOST OF THE CLOUD COVER AND DEW
POINTS HAVE FALLEN INTO THE MID/UPR 40S.

EXPECT THE WAVE TO CONTINUE TO LIFTING NORTHEAST THROUGH THE OHIO
VALLEY THIS EVENING...PULLING WITH IT THE BULK OF THE PRECIPITATION.
ANTICIPATE THAT NORTHERN IL/NORTHWEST IN WILL REMAIN DRY...WHICH IS
WELCOME NEWS FOR MANY AREAS THAT CONTINUE TO OBSERVE FLOODING THIS
AFTERNOON. UNFORTUNATELY THE DRY WEATHER MAY ONLY BE BRIEF AS YET
ANOTHER SHORTWAVE AND 500MB TROUGH ARE POISED TO ARRIVE FROM THE
NORTHWEST TUE AFTERNOON AND BRING WITH IT A CHANCE FOR SHOWERS.

OVERNIGHT TEMPS WILL SLOWLY RADIATE INTO THE UPR 40S FOR AREAS ALONG
AND NORTH OF I-88 IN NORTHERN IL. SOUTH OF THIS LINE TEMPS MAY BE A
FEW DEGREES WARMER GIVEN THE SLIGHTLY LONGER PERIOD OF CLOUD
COVER...WITH TEMPS ARND 50. ACROSS THE FAR SOUTHERN PORTIONS OF THE
CWFA TEMPS MAY HOLD IN THE LOWER 50S...HOWEVER THIS WILL HINGE UPON
THE CLOUDS OVERNIGHT.

TUESDAY THROUGH WEDNESDAY...
AS ELUDED TOO EARLIER...A TROUGH AXIS IS POISED TO ARRIVE ACROSS THE
WESTERN GREAT LAKES REGION MIDDAY TUE. WHILE THE SYSTEM APPEARS TO
REMAIN RELATIVELY WEAK...SOME INSTABILITY IS NOTED AMONGST A FEW
FORECAST SOLUTIONS. AT THE ONSET IT IS POSSIBLE THAT A FEW
THUNDERSTORMS MAY OCCUR...HOWEVER THIS COULD BE DRIVEN OR ENHANCED
FROM THE POTENTIAL FOR SOME DIFFERENTIAL HEATING AND COOLER AIR
ALOFT...AS 850MB TEMPS ARE PROGGED TO BE ARND 4 TO 6 DEG C. CURRENT
GUIDANCE HAS PROGGED SFC TEMPS TO WARM INTO THE UPR 60S NORTH OF
I-88...WHILE LOCATIONS SOUTH WILL WARM TO ARND 70 OR POSSIBLY THE
LOWER 70S FROM PONTIAC TO KANKAKEE.

FLOW REMAINS RELATIVELY PROGRESSIVE AS THE 500MB WAVE CONTINUES TO
PUSH EAST DURING WED MORNING. ENOUGH MOISTURE MAY LINGER WED MORNING
TO PRODUCE A SLIGHT CHC OF SHOWERS...HOWEVER RIDING ALONG THE
WESTERN PERIPHERY IS A BROAD ANTI-CYCLONIC FLOW THAT SHOULD AID IN
FURTHER EROSION OF THE LLVL MOISTURE. THIS FEATURE WILL THEN RESIDE
OVER THE REGION THROUGH MOST OF THUR. MORE SEASONAL AIRMASS PUSHES
OVERHEAD FOR THUR WITH TEMPS HOLDING MAINLY IN THE MID 60S. WINDS
MAY TURN EASTERLY AND HOLD TEMPS IN THE UPR 50S ALONG THE IMMEDIATE
LAKESHORE COUNTIES OF FAR NORTHEAST IL.

THURSDAY THROUGH SUNDAY...
500MB TROUGH AXIS CONTINUES TO PIVOT EAST FOR THE FIRST FEW DAYS OF
THE EXTENDED...THEN A HIGH AMPLITUDE RIDGE IS PROGGED TO BEGIN
DEVELOPING ACROSS THE PAC-NW OVER THE SECOND HALF OF THE WEEKEND. IF
THE UPSTREAM RIDGE DEVELOPS AS PROGGED BY NUMEROUS ENSEMBLE
MEMBERS...LATE WEEKEND INTO EARLY NEXT WEEK COULD FEATURE A SEASONAL
AIRMASS OVER THE GREAT LAKES REGION OR POSSIBLY SLIGHTLY BELOW
SEASONAL TEMPERATURES.

A WEAK 850MB THERMAL RIDGE SLIDES OVER THE GREAT LAKES REGION AT THE
ONSET OF THE CURRENT EXTENDED FORECAST AS A RESULT OF A WEAKENING
FRONTAL BOUNDARY WEDGED BETWEEN TWO ADVERTISED ANTI-CYCLONIC FLOW
FEATURES. MEANWHILE...MUCH WARMER AIR BUILDS ACROSS THE PAC-NW UNDER
AN ADVERTISED HIGH AMPLITUDE RIDGE. THE DOWNSTREAM WAVE FUNCTION FOR
THE GREAT LAKES REGION CURRENTLY INDICATES A NEARLY NEUTRAL 850MB
TEMPS. BASED ON THE AFOREMENTIONED...CONFIDENCE REMAINS RELATIVELY
HIGH THAT TEMPS WILL MAINLY BE IN THE 60S TO POSSIBLY LOW 70S
THROUGHOUT THE BULK OF THE EXTENDED FORECAST. TWO FEATURES THAT WILL
DRIVE TEMPS AT THE SFC WILL BE CLOUD COVER AND SFC WINDS.

IN ADDITION TO THE RELATIVELY QUIET PATTERN FOR THE EXTENDED...IT IS
ALSO LEANING TOWARDS A DRY REGIME AS WELL. A WEAK FRONTAL BOUNDARY
IS PROGGED TO ARRIVE SAT. MANY SOLUTIONS HAVE STEADILY LEANED
TOWARDS A MOISTURE STARVED FRONTAL PASSAGE...THUS COULD SEE THIS
BEING NOTHING MORE THAN A WIND SHIFT AS TIME PROGRESSES.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 22Z...

* IMPROVING CEILING/VIS TRENDS AS RAIN PULLS AWAY TO THE EAST.

* LIGHT VARIABLE WINDS BECOMING NNW-NW THIS EVENING.

RATZER

//DISCUSSION...UPDATED 22Z...

MAIN FORECAST CONCERN IS THE RATE OF IMPROVEMENT IN CEILINGS AND
VISIBILITY AS RAIN PULLS OFF TO THE EAST AND WEAK HIGH PRESSURE
RIDGE BUILDS INTO THE AREA THIS EVENING. RFD/ORD/DPA HAVE IMPROVED
TO SOLID MVFR RANGE...EVEN VFR AT RFD...WHILE IFR LINGERS AT MDW
AND GYY. IMPROVING TREND IS GOING A LITTLE SLOWER...BY PERHAPS A
COUPLE OF HOURS ACROSS EASTERN TERMINALS...BUT OVERALL TREND OF
FORECAST STILL LOOKS REASONABLE.

PREVIOUS DISCUSSION FROM 18Z...

MID LEVEL LOW CURRENTLY OVERHEAD LOCAL TERMINALS WILL CONTINUE
MOVING ENE THIS AFTERNOON. -RA TO END FOR NE IL EARLY AFTERNOON
AS EXTRAPOLATION AND MODEL FORECAST POSITION OF MID LEVEL LOW

KEPT BOUNDARY LAYER MOIST BUT AS 700 HPA LOW AND ITS ASSOCIATED
SFC LOW...CURRENTLY IN CENTRAL IND...CONTINUE OFF TO THE ENE
DURING THE REST OF THE AFTERNOON THE ADVECTION OF LOWER SFC DEW
POINTS ALREADY SPREADING S FROM WI ACROSS NORTHERN IL WILL
CONTINUE. THIS DURING OF THE BOUNDARY LAYER HAS RESULTED IN
UPSTREAM CIGS RISING FROM IFR TO MVFR AND EVENTUALLY TO VFR.
EXPECT THIS TREND TO PERSIST/SPREAD ACROSS LOCAL AREA WITH VFR BY
AROUND 21Z.

.MARINE...

245 PM...LOW PRESSURE OVER NORTHERN INDIANA WILL LIFT NORTHEAST TO
NEAR LAKE ERIE TONIGHT. AS A SECOND LOW DROPS OUT OF SOUTHERN
MANITOBA TO LAKE SUPERIOR BY TOMORROW...WINDS OVER THE LAKE WILL
GRADUALLY SHIFT FROM NORTH TO NORTHEASTERLY OVERNIGHT TO WESTERLY
TOMORROW. THE 2 LOW PRESSURE SYSTEMS WILL MERGE INTO A SINGLE LOW
OVER SOUTHERN QUEBEC TOMORROW EVENING. A WEAK SFC TROUGH WILL
EXTEND WWD OVER THE WRN GREAT LAKES REGION...KEEPING A FAIRLY WEAK
GRADIENT OVER THE LAKE FOR THE NEXT FEW DAYS. THE STRONGEST WINDS
ARE SETTING UP FOR WEDNESDAY AS A MODEST SURGE OF COOLER AIR
OVERSPREADS THE LAKE AS THE CONSOLIDATED LOW PULLS OFF TO THE EAST
AND HIGH PRESSURE BUILDS ACROSS THE NRN PLAINS TO THE MISSOURI
VALLEY. THIS HIGH WILL CONTINUE TO SPREAD EAST ACROSS THE MIDDLE
AND UPPER MISSISSIPPI VALLEY AND INTO THE GREAT LAKES REGION. BY
WEDNESDAY NIGHT AND THURSDAY...A SFC RIDGE AXIS WILL CROSS THE
LAKE...BRINGING LIGHTER AND MORE VARIABLE WINDS.
