AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1058 AM CST MON NOV 14 2011

.DISCUSSION...
1040 AM CST

QUASI-STATIONARY FRONTAL BOUNDARY REMAINS STRETCHED ACROSS CENTRAL
ILLINOIS EXTENDING NORTHEAST THROUGH NORTH CENTRAL INDIANA. THIS
BOUNDARY SHOULD BEGIN TO SAG SOUTHEAST OF THE AREA THIS
EVENING...WHICH SHOULD KEEP MOST OF THE MOISTURE ACROSS SOUTHERN
ILLINOIS AND SOUTHERN INDIANA TUE. VISIBLE IMAGERY CONTINUES TO
INDICATE ABUNDANT CLOUD COVER ACROSS THE ENTIRE REGION LATE THIS
MORNING...AND LATEST GUIDANCE INDICATES THAT THIS TREND WILL
PERSIST THROUGH THIS AFTN EARLY EVE AS WELL. SOME CLEARING WAS
OCCURRING ACROSS CENTRAL IOWA...HOWEVER BASED ON THE CURRENT TREND
OF THIS CLEARING IT WOULD NOT ARRIVE OVER NORTHERN ILLINOIS UNTIL
AFTER OR AROUND SUNSET. THUS MAX TEMPS TODAY HAVE BEEN TWEAKED
DOWN A COUPLE DEGREES FOR PORTIONS OF NORTHERN ILLINOIS. CLOSER TO
THE FRONTAL BOUNDARY TEMPS HAVE SOARED HIGHER INTO THE MID/UPR 60S
ACROSS PORTIONS OF CENTRAL ILLINOIS. IT DOES NOT APPEAR THAT THIS
BOUNDARY WILL PUSH FURTHER NORTH...HOWEVER IT WILL BE VERY CLOSE.
THUS HAVE NOT ADJUSTED TEMPS ALONG MY SOUTHERN CWFA.

WSR-88D REGIONAL RADAR MOSAIC ALSO INDICATES CONSIDERABLE SHOWERS
AND ISOLATED THUNDER JUST NORTH OF THE FRONTAL BOUNDARY SLIDING
NORTHEAST. THE DEEPER CLOUDS ARE CURRENTLY OVER FAR NORTHEAST
ILLINOIS AND APPEAR TO BE SLOWLY PEELING AWAY FROM THE REGION.
HAVE MAINTAINED SOME ISO THUNDER WORDING OVER FAR NORTHEAST
ILLINOIS THROUGH THIS AFTERNOON AS WELL AS NORTHWEST
INDIANA...HOWEVER FEEL THIS WILL BE FOCUS MORE OVER NORTHWEST
INDIANA.

BEACHLER

&&

.PREV DISCUSSION...
300 AM CST

THE FAIRLY LOW AMPLITUDE...BUT HIGHLY PROGRESSIVE FLOW PATTERN ALOFT
WILL KEEP A VERY CHANGEABLE WEATHER PATTERN ACROSS NORTHERN ILLINOIS
AND NORTHWESTERN INDIANA FOR THE NEXT SEVERAL DAYS.

FOR THE REMAINDER OF THE NIGHT AND THROUGH MONDAY...THE MAIN CONCERN
WILL BE INCREASING PCPN CHANCES ACROSS THE AREA.  A WEAK FRONTAL
BOUNDARY EXTENDS FROM NEAR LAKE ERIE...THROUGH CENTRAL IL/IN...TO A
LOW PRESSURE CENTER OVER CENTRAL KANSAS.  AS THE SFC LOW RIPPLES
ALONG THE BOUNDARY...THE FRONT WILL RETURN NORTHWARD AS A WARM
FRONT...PENETRATING BACK INTO THE SRN PORTIONS OF THE CWA BY THIS
AFTERNOON.  STRONG WARM ADVECTION SOUTH OF THE BOUNDARY AND STRONG
ISENTROPIC LIFT...COMBINED WITH ADDED FOCUS OF THE SFC WAVE WILL
BRING INCREASING CHANCES OF PCPN TO THE CWA.  THE BOUNDARY AND THE
SFC WAVE WILL PROVIDE THE GREATEST FOCUS OVER THE SERN PORTIONS OF
THE CWA...AND INDEED...WILL MAINTAIN LIKELY POPS SOUTHEAST OF A LINE
FROM VALPARAISO TO WATSEKA.  GIVEN THE STRENGTH OF THE WARM
ADVECTION AND LIFT...SCT SHOWERS WILL BE QUITE POSSIBLE EVEN AS FAR
NORTHWEST AS THE ROCKFORD AREA...BUT PCPN AMOUNTS SHOULD TAPER OFF
WITH DISTANCE AWAY FROM THE BOUNDARY.  MODEST ELEVATED INSTABILITY
ALONG AND NORTH OF THE BOUNDARY WILL KEEP A CHANCE FOR SOME
ISOLATED...EMBEDDED THUNDER WITHIN THE PCPN SHIELD.

GIVEN THE VERY FAST FLOW PATTERN ALOFT...THE SFC WAVE AND ASSOCIATED
UPPER LEVEL SHORT WAVE WILL QUICKLY SHEAR OUT AND PCPN CHANCES WILL
QUICKLY TAPER OFF BY LATE THIS AFTERNOON.  AS WEAK HIGH PRESSURE
BUILDS IN BEHIND THE FRONT TONIGHT...EXPECT THAT THE SKY WILL
QUICKLY CLEAR OUT AFTER SUNSET...AND WITH A MUCH DRIER AIRMASS
OVERSPREADING THE AREA...TEMPERATURES OVERNIGHT SHOULD QUICKLY DROP
OFF AS WELL...BOTTOMING OUT IN THE LOWER 30S NORTH OF I-80 AND THE
MIDDLE TO UPPER 30S TO THE SOUTH.

ANOTHER WARM...WINDY DAY IS SETTING UP FOR TUESDAY.  A
STRONG...QUICK MOVING SYSTEM WILL SCOOT ALONG THE CANADIAN
BORDER...WITH A TRAILING SFC TROUGH AND STRONG COLD FRONT EXTENDING
TO THE SOUTH.  THE MODELS ARE RELATIVELY CONSISTENT IN SWEEPING THE
FRONT ACROSS THE CWA TUESDAY AFTERNOON.  STRONG SOUTHWEST WINDS
WILL ALLOW FOR TEMPERATURES TO CLIMB BACK INTO THE LOWER TO MIDDLE
60S FOR THE SERN PORTIONS OF THE CWA.  WITH THE EXPECTED TIME OF THE
FROPA FOR THE NWRN PORTIONS OF THE CWA TO OCCUR BEFORE THE TYPICAL
TIME OF MAX TEMPERATURE.  THE ROCKFORD AREA WILL NOT HAVE THE SAME
OPPORTUNITY TO WARM UP AS MUCH AND TEMPS THERE SHOULD ONLY TOP OUT
IN THE MIDDLE 50S. TEMPERATURES ACROSS THE AREA ARE EXPECTED TO
DECREASE THROUGH THE AFTERNOON HOURS FOLLOWING THE FRONTAL PASSAGE.
THERE WILL BE LITTLE OPPORTUNITY FOR ANY RETURN FLOW OF MOISTURE
AHEAD OF THIS FRONT AS THE GULF OF MEXICO WILL BE CUT OFF BY HIGH
PRESSURE EXTENDING THROUGH THE SERN CONUS INTO THE GULF REGION.
THEREFORE...DO NOT EXPECT ANY PCPN WITH THE FROPA.  WHILE TUESDAY
SHOULD BE QUITE BREEZY...DO NOT EXPECT WINDS TO GET QUITE AS STRONG
AS WHAT OCCURRED SUNDAY...WITH GUSTS ONLY AROUND 25MPH.

A VERY COOL...DRY AIRMASS WILL FILTER OVER THE REGION BEHIND THE
FRONT.  OVERNIGHT LOW TEMPERATURES FOR WEDNESDAY MORNING SHOULD
RANGE FROM THE UPPER 20S OVER THE ROCKFORD AREA TO THE LOWER 30S
SOUTH OF THE KANKAKEE RIVER. WEDNESDAY WILL BE A RATHER COOL DAY
WITH HIGHS STRUGGLING TO CLIMB MUCH ABOVE 40F.  WITH CLEAR SKIES AND
CONTINUED COLD ADVECTION...THURSDAY MORNING SHOULD BE EVEN
COOLER...WITH LOWS ACROSS MUCH OF THE CWA IN THE 20S.  ONLY DOWNTOWN
CHICAGO SHOULD REMAIN ABOVE FREEZING...BUT MUCH OF THE CHICAGO METRO
AREA SHOULD DROP BELOW 30F.  THURSDAY WILL LIKELY BE THE COOLEST DAY
OF THIS AUTUMN AS HIGHS OVER NCNTRL ILLINOIS SHOULD ONLY REACH THE
UPPER 30S...WHILE LOCATIONS SOUTH OF THE KANKAKEE/ILLINOIS RIVERS
STRUGGLE TO CLIMB INTO THE LOWER 40S.

THE UNSETTLED WEATHER WILL CONTINUE INTO THE EXTENDED FORECAST
PERIOD...FRIDAY THROUGH SUNDAY.  ANOTHER NORTHERN STREAM SYSTEM IS
EXPECTED TO DROP OUT OF THE CANADIAN ROCKIES BY FRIDAY MORNING AND
QUICKLY TRACK ACROSS THE NORTHERN PLAINS TO THE UPPER GREAT LAKES BY
FRIDAY NIGHT.  THIS WILL SET UP ANOTHER PERIOD OF STRONG WARM
ADVECTION AT THE SURFACE...AND THIS TIME...THE GULF OF MEXICO SHOULD
BE WIDE OPEN FOR A RETURN OF MOISTURE AS WELL.  PCPN CHANCES SHOULD
QUICKLY INCREASE FOR SATURDAY AND SOME THUNDER IS NOT OUT OF THE
QUESTION AS WELL.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 16Z...

* VARIABLE WINDS REMAINING UNDER 5KT THIS MORNING...BUT BECOMING
  MORE SOUTHEAST AND SLIGHTLY INCREASING IN THE AFTERNOON.

* VFR CEILINGS BUT WITH LOW POTENTIAL FOR MVFR CEILINGS AT MDW
  ASSOCIATED WITH SHRA.

* INCREASED CHANCE FOR SHOWER ACTIVITY LATE MORNING INTO EARLY
  AFTERNOON FOR BOTH TERMINALS...BUT WILL BE INTERMITTENT WITH NO
  REAL PREVAILING VIS RESTRICTION EXPECTED.

RODRIGUEZ

//DISCUSSION...UPDATED 12Z...

MAIN CHALLENGES WILL BE EVOLUTION OF SHOWER ACTIVITY INTO EARLY
AFTERNOON ALONG WITH WIND DIRECTION AS LOW PRESSURE MOVES ACROSS
THE TERMINALS. LOW PRESSURE OVER MISSOURI WILL MOVE NORTHEASTWARD
ALONG A NEARLY STATIONARY FRONTAL BOUNDARY EXTENDING NORTHEASTWARD
TOWARD LAKE ERIE. THE LOW WILL PASS TO THE SOUTH OF THE TERMINALS
THIS AFTERNOON WITH A TROUGH AXIS EXTENDING TO ITS NORTH. THIS
WILL CAUSE HAVOC WITH PREVAILING WIND DIRECTION THROUGH EARLY
AFTERNOON...ESPECIALLY ACROSS THE CHICAGO AREA TERMINALS. SPEEDS
WILL BE LIGHT DURING THAT TIME HOWEVER. WINDS WILL THEN TURN
STEADY FROM THE SOUTHWEST DURING THE MID AFTERNOON WITH SPEEDS
COMING UP TO 8-10 KT OR SO. SPEEDS WILL DROP OFF DURING THE LATE
EVENING AS WINDS TURN MORE SOUTHERLY.

THE TERMINALS ARE CURRENTLY BETWEEN TWO AREAS OF FORCING FOR
PRECIPITATION. THE FIRST LIES TO THE SOUTH ALONG THE MAIN TRACK OF
THE LOW AND THE STATIONARY FRONTAL BOUNDARY. THIS SHOULD BE THE
MORE ACTIVE FOCUS FOR SHOWERS AND SOME THUNDERSTORMS INTO EARLY
AFTERNOON. THE FRONT WILL DRIFT NORTHWARD PUSHING PRECIP
NORTHWARD AS WELL BUT THIS WILL HAVE A HARD TIME MAKING IT TO EVEN
MDW BUT THEY AND GYY WILL HAVE THE BEST CHANCES FOR SHOWERS.
CANNOT RULE OUT THUNDER POSSIBILITY AS FAR NORTH AS GYY BUT THE
CHANCE IS PRETTY LOW AND FOCUSED MORE TO THE SOUTH. IF RAIN CAN
MANAGE TO ORGANIZE ENOUGH THIS FAR NORTH THEN MVFR CIGS WILL BE A
POSSIBILITY. AN UPPER LEVEL TROUGH MOVING NORTHEASTWARD FROM THE
CENTRAL PLAINS WILL TRACK ACROSS FAR NORTHERN ILLINOIS AND PROVIDE
ADDITIONAL FOCUS FOR SOME SPRINKLES OR LIGHT RAIN BUT THIS MAY BE
A PRETTY SPOTTY GIVEN HOW DRY THE LOWER ATMOSPHERE IS. DRIER AIR
WILL THEN BRING AN END TO PRECIP CHANCES ACROSS THE TERMINALS
DURING THE AFTERNOON.

MDB

//ORD AND MDW CONFIDENCE...UPDATED 16Z...

* MEDIUM CONFIDENCE WITH WIND SPEED AND DIRECTION.

* HIGH CONFIDENCE WITH CEILINGS...BUT WITH LOW CONFIDENCE OF MVFR
  CEILING POTENTIAL AT MDW.

* HIGH CONFIDENCE IN SHRA OCCURRING AT BOTH TERMINALS AND TRENDS
  INTO THE AFTERNOON.

RODRIGUEZ

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

TUESDAY NIGHT THROUGH FRIDAY...VFR. SLIGHT CHANCE SHRA FRIDAY
                               NIGHT.

SATURDAY AND SUNDAY...CHANCE SHRA...MVFR POSSIBLE.

.MARINE...
259 AM CST

WINDS APPEAR TO BE LOCKED INTO THE SOUTHWEST QUADRANT FOR THE
DURATION OF THIS WEEK...VARYING AT TIMES FROM WEST TO SOUTH.  A LOW
PRESSURE SYSTEM THAT PASSED NORTH OF THE LAKES SUNDAY AND BROUGHT A
PERIOD OF SOUTH TO SOUTHWEST GALES HAS NOW MOVED INTO HUDSON BAY.
BEHIND THIS LOW A WEAK RIDGE WILL CROSS THE LAKE TODAY.  WEST WINDS
WILL BACK SOUTH THIS AFTERNOON AND THEN VEER AGAIN TO SOUTHWEST
OVERNIGHT AHEAD OF THE NEXT TROUGH AND ASSOCIATED LOW PRESSURE
CENTER.  THE LOW TONIGHT ALSO WILL PASS NORTH OF THE LAKES AND IS
NOT EXPECTED TO BE QUITE STRONG ENOUGH TO GENERATE GALES.  FOLLOWING
QUICKLY ON ITS HEELS HOWEVER IS A STRONGER SYSTEM MOVING IN TUESDAY
EVENING...WHICH LIKELY WILL PUSH WEST WINDS OR AT LEAST GUSTS INTO
THE GALE RANGE FOR A TIME TUESDAY NIGHT INTO WEDNESDAY MORNING.  THE
PRESSURE GRADIENT WEAKENS FOR A DAY OR SO...FROM WEDNESDAY AFTERNOON
THROUGH THURSDAY...BEFORE RAPIDLY INCREASING TO SOUTHWEST GALES BY
FRIDAY MORNING.  FRIDAY IN FACT LOOKS VERY MUCH LIKE THIS SUNDAY WE
JUST FINISHED...WITH GUSTS OVER 40 KNOTS AGAIN A POSSIBILITY.

DESPITE THE PERSISTENT SOUTHWEST FETCH EARLY THIS WEEK...WAVE GROWTH
APPEARS TO BE SOMEWHAT INHIBITED BY THE RELATIVELY WARMER AIR
FLOWING OVER THE COOLER WATER.  WHEN COLDER AIR DOES ARRIVE BY
MIDWEEK...THIS WILL OCCUR AS WINDS ARE IN A MORE WESTERLY
PHASE...THUS PRODUCING A SHORTER FETCH WITH WHICH TO WORK.
