AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
400 AM CDT WED SEP 19 2012

.DISCUSSION...
332 AM CDT

EARLY THIS MORNING THE WSR-88D KLOT VAD WIND PROFILE DISPLAY
INDICATES WINDS JUST OFF OF THE DECK AT 1KFT AGL HOVERING ARND 10-15
KT. THIS HAS MAINTAINED JUST ENOUGH FRICTION TO PREVENT TEMPS AT THE
SFC FROM COMPLETELY RADIATING FURTHER INTO THE LOW/MID 30S. IN
ADDITION SFC OBS AT 3 AM CDT HAVE ALREADY BEGUN REPORTING WINDS FROM
THE S/SW. DEW PTS IN MANY LOCATIONS HAVE ALSO BEEN ON THE RISE...AND
THE WATER VAPOR IMAGERY DEPICTS THE MOISTURE WAS BEGINNING TO POOL
SOUTHEAST AHEAD OF THE NEXT SYSTEM. NONETHELESS EXPECT JUST BEFORE
SUNRISE TEMPS TO DROP A FEW DEGREES. IT APPEARS NOW THAT ANY FROST
FORMATION WILL BE LIMITED TO ELEVATED EXPOSED SURFACES ALONG AND
WEST OF A CRYSTAL LAKE TO KANKAKEE LINE.

500MB TROUGH AXIS WAS SLOWLY PIVOTING EAST THIS MORNING ACROSS LOWER
MI...WITH THE SFC RIDGE POSITIONED NEAR SOUTHERN IN. HOWEVER WITH
THE PROGRESSIVE NATURE OF THIS SYSTEM...EXPECT THE TIGHT PRESSURE
GRADIENT THAT HAS REMAINED OVER IA/MN TO ARRIVE MID/LATE MORNING.
MIXING WILL BECOME OPTIMIZED LATER THIS MORNING INCREASING BEYOND
850MB AND SHUD AID IN KEEPING DEW PTS DOWN IN THE MID 30S THRU
MIDDAY AND THE AFTN HOURS. BREEZY CONDS WILL STEADILY DEVELOP AS A
RESULT OF THE MAXIMIZED MIXING...AND EXPECT OCCASIONAL WIND GUSTS
ARND 30-35 MPH. COULD SEE A FEW GUSTS TO 40 MPH...WHICH WILL FALL
UNDER WIND ADVISORY CRITERIA. RED FLAG CONDS DO APPEAR TO
DEVELOP...ALTHOUGH THE MIN RH VALUES ARE CLOSE IN THE MID/UPR 20
PERCENT. WHILE 10 HR FUEL MOISTURE LEVELS ARE PROGGED TO BE ARND 8
TO 10 PERCENT...MORE THAN LIKELY THE 1 HR FUEL MOISTURE WILL BE
MUCH LOWER. HAVE DECIDED TO HEDGE TOWARDS RED FLAG CONDS BEING
REACHED TODAY AND HOISTED A RED FLAG WARNING.

CLOUDS WILL BE ON THE INCREASE IN THE MID AFTN HOURS AS THE
NEXT VORT MAX QUICKLY APPROACHES FROM THE NORTHWEST. GUIDANCE HAS
CONTINUED TO SUGGEST THIS NEXT SYSTEM WILL REMAIN WELL NORTHWEST OF
THE CWFA...WITH A PASSAGE ACROSS THE UPPER MIDWEST/NORTHERN GREAT
LAKE OVERNIGHT. HOWEVER A FRONTAL BOUNDARY WILL EXTEND SOUTH FROM
THIS SYSTEM...WHICH COULD BRING A PERIOD OF PRECIP TO THE CWFA
SOMETIME ARND 00Z THRU 06Z. INSTABILITY LOOKS TO BE
MARGINAL...HOWEVER IS WORTH A MENTION OF SLT CHC THUNDER IN THE
FORECAST. THE FAR SOUTHERN CWFA COULD MISS OUT ALL TOGETHER WITH
PRECIP TONIGHT.

WITH GOOD SFC HEATING AND STRONG WARM AIR ADVECTION THIS
AFTN...COUPLED WITH THE 850MB THERMAL RIDGE OF 10-13 DEG C SLIDING
OVERHEAD THIS AFTN...TEMPS SHUD EASILY WARM INTO THE LOW/MID 70S.THE
WARMEST TEMPS WILL BE ALONG AND SOUTHWEST OF A ROCKFORD TO KANKAKEE
LINE...AND COULD SEE A FEW LOCATIONS PSBLY WARM INTO THE UPR 70S
BEFORE THE THICKER CLOUDS ARRIVE. TEMPS OVERNIGHT SHUD ONLY COOL
INTO THE MID/UPR 40S ALONG AND NORTH OF I-80...WHILE LOCATIONS
FURTHER SOUTH COULD REMAIN IN THE LOW 50S. IF CLOUDS DEPART THE
REGION FASTER THAN TEMPS COULD PSBLY COOL FURTHER.

CONFIDENCE...HIGH.

THURSDAY THROUGH SATURDAY...
500MB TROUGH CONTINUES TO SLIDE SOUTHEAST ACROSS THE UPPER
MIDWEST/GREAT LAKES...AS THE UPSTREAM RIDGE BECOMES FURTHER
AMPLIFIED AS WELL AS THE RIDGE OVER THE CANADIAN MARITIME. THIS
SUGGESTS THAT THE TROUGH OVER THE GREAT LAKES WILL REMAIN AND
POSSIBLY STRENGTHEN. A SERIES OF WEAK WAVES ARE PROGGED TO PIVOT
ARND THE TROUGH AXIS THUR EVE/FRI MORN...AND ANOTHER FRI NGT/EARLY
SAT. GUIDANCE DOES DIFFER AFT SAT ON WHETHER ANTI-CYCLONIC FLOW WILL
PUSH THE TROUGH FURTHER EAST AND BRING DRIER AIR INTO THE REGION.

IN THE THUR-SAT PERIODS...IT APPEARS THUR WILL LIKELY BE THE WARMEST
WITH TEMPS HOVERING ARND 70 FOR MUCH OF THE CWFA UNDER A LLVL
WESTERLY FLOW. MIXING DOESN/T APPEAR TO BE AS ROBUST AS WED
AFTN...WHICH SHUD ALLOW RH VALUES TO FALL TO ARND 30 PERCENT.

FRI WILL BE TRENDING COOLER WITH TEMPS HOLDING IN THE MID 60S...AND
FOR SAT SEVERAL LOCATIONS ACROSS THE NORTHWEST CWFA COULD STRUGGLE
TO WARM BEYOND THE UPR 50S. THE DRIVING FACTORS IN KEEPING TEMPS IN
THE 50S WOULD BE THE THICK CLOUD COVER...AND 0 TO -2 DEG C 850MB
TEMPS THAT SLIDE OVERHEAD. A FEW OF THE OPERATIONAL SOLUTIONS HINT
AT A POTENT FALL SYSTEM DEVELOPING ACROSS THE GREAT LAKES
SAT...WHICH COULD RESULT IN SAT BEING A VERY COOL/CLOUDY/WET DAY.

CONFIDENCE...MEDIUM.

SUNDAY THROUGH TUESDAY...
ENSEMBLES REMAIN IN RELATIVELY DECENT AGREEMENT WITH THE TWO AREAS
OF HIGH-AMPLITUDE RIDGING SLOWLY WEAKENING THROUGHOUT THE LONGER
TERM. THE BY-PRODUCT OF THIS SCENARIO IS THAT THE 500MB TROUGH
PARKED OVER THE GREAT LAKES REGION WILL BEGIN TO DISSOLVE. UTILIZING
THE RELATIVE MEASURE OF PREDICTABILITY IMAGES AND THE LATEST
ANALYSIS DEPICTS THIS RIDGE RE-STRENGTHENING ACROSS THE CANADIAN
ROCKIES IN THE FINAL PERIODS OF THE EXTENDED. IF THIS WOULD VERIFY
THE PLACEMENT COULD RESULT IN A PROLONGED PERIOD OF DRY NORTHWEST
FLOW.

SUN/MON ANTI-CYCLONIC FLOW SHUD DOMINATE THE LLVL FLOW AND PROVIDE A
DRY WITH GRADUAL WARMING SETUP...OR RETURN TO SEASONAL CONDS. WITH
THE POTENT 500MB VORT POSITIONED TO THE NORTH...IT IS STILL POSSIBLE
FOR A WEAK LOBE OF VORTICITY TO PIVOT ARND THE TROUGH AXIS AND COULD
PUSH INTO THE NORTHERN PERIPHERY OF THE SFC RIDGE...PROVIDING A
MINIMAL CHC FOR PRECIP AND CLOUDS. AT THIS TIME THIS APPEARS TO BE A
LOW CONFIDENCE OUTCOME. 850MB THERMAL TROUGH OF 0 TO 2 DEG C WILL
TRAVERSE THE CWFA SUN...WARMING TO 4 TO 6 DEG C MON. THUS IT APPEARS
THE COOLEST DAY OF THE EXTENDED WILL BE SUN...THEN SHUD APPROACH
SEASONAL CONDS MON OR IN THE LOW 70S.

THEN FOR THE LATER PERIODS THE UPSTREAM
RIDGE BEGINS TO WEAKEN AND DRIFT EAST TOWARDS THE CANADIAN
ROCKIES...WHILE THE NORTH ATLANTIC RIDGE IS PROGGED TO WEAKEN AS
WELL. WHICH SHUD AID IN A FURTHER EAST/NORTHEAST PUSH OF THE PESKY
500MB TROUGH. TEMPS CONTINUE TO WARM ALOFT AS THE LLVL FLOW APPEARS
TO TRANSITION INTO A SOUTHWEST SETUP. THIS SHUD ALLOW TUE TO WARM
PSBLY INTO THE MID 70S...BUT APPEARS TO REMAIN DRY.

CONFIDENCE...HIGH/MEDIUM.

.FIRE WEATHER...
303 PM CDT

HAVE SOME HEIGHTENED FIRE WEATHER CONCERNS...PRIMARILY
ACROSS THE WESTERN AND NORTHWESTERN CWA WHERE DRIEST CONDITIONS
REMAIN WEDNESDAY. SOUTH-SOUTHWEST WINDS WILL INCREASE DRAMATICALLY
BY MIDDAY WEDNESDAY WITH VERY LOW DEWPOINTS IN PLACE FOLLOWING COLD
MORNING LOWS. MIXING LOOKS T0 INCREASE TO AROUND 850 MB RESULTING IN
GUSTS INTO THE 30 TO 35 KT RANGE MAINLY NORTH OF INTERSTATE 80.
SOUNDINGS DO NOT SHOW SIGNIFICANT DRYING ALOFT SO DEW POINTS DO NOT
LOOK TO MIX TO LOWER VALUES THROUGH EARLY AFTERNOON. IN
ADDITION...AN APPROACHING LOW PRESSURE SYSTEM WILL BRING A MODEST
INCREASE IN MOISTURE DURING THE LATE AFTERNOON. SO IT APPEARS THAT
MIN RH VALUES WILL FALL TO AROUND 25 PERCENT ACROSS THE WEST AND
NORTHWEST WITH SLIGHTLY HIGHER VALUES ELSEWHERE. ONE POTENTIAL
CAVEAT WOULD BE AN OVERABUNDANCE OF CLOUD COVER LIMITING WIND
GUSTS. A FIRE WEATHER WATCH OR RED FLAG WARNING IS POSSIBLE BUT AT
THE MOMENT WITH EXPECTED CONDITIONS LOOKING BORDERLINE AND SEVERAL
FACTORS POTENTIALLY SUPPORTING HIGHER RH/LOWER WINDS ETC. WILL
HOLD OFF FOR NOW.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 09Z...

* STRONG GUSTY SOUTHWEST WINDS.
* POTENTIAL FOR SHOWERS LATE WEDNESDAY EVENING.
* POTENTIAL FOR LLWS LATE WEDNESDAY EVENING. BMD

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

OVERNIGHT...A SURFACE RIDGE OVER THE MID MISSISSIPPI VALLEY WILL
MOVE EAST...SLIDING JUST SOUTH OF THE AREA TERMINALS AND ALLOWING
WINDS TO BECOME VERY LIGHT TO CALM. AS THE RIDGE BEGINS TO EXIT TO
THE EAST WEDNESDAY MORNING...SOUTHWESTERLY WINDS WILL BEGIN TO
INCREASE AS LOW PRESSURE DEEPENS ACROSS THE CANADIAN PRAIRIES AND
THE PRESSURE GRADIENT TIGHTENS. A TRAILING COLD FRONT WILL PUSH EAST
TOWARDS THE GREAT LAKES REGIONS AND VERY STRONG PRESSURE FALLS WILL
DEVELOP AHEAD OF THE FRONT WHICH WILL HELP TO INCREASE THE WIND
GUSTS WELL ABOVE 20 KT BY EARLY AFTERNOON...AND ABOVE 30 KT MID
AFTERNOON INTO THE EVENING. WINDS WILL CONTINUE GUSTING AFTER SUNSET
THOUGH ARE EXPECTED TO TAPER BACK BELOW 30 KT AS THE SURFACE TROUGH
NEARS. STRONG WINDS WILL PERSIST ALOFT HOWEVER...WITH 50+ KT WINDS
EXPECTED AT 020 CAUSING LOW LEVEL WIND SHEAR. PRECIPITATION WITH THE
FRONT IS STILL A BIT UNCERTAIN WITH RELATIVELY DRY CONDITIONS IN
PLACE AND FORCING BECOMING A LITTLE MORE DISORGANIZED OVERNIGHT.
ONCE THE COLD FRONT SWEEPS THROUGH...WINDS SHOULD QUICKLY TAPER AS
THEY TURN NORTHWESTERLY. BMD

//ORD AND MDW CONFIDENCE...UPDATED 09Z...

* HIGH CONFIDENCE IN WIND DIRECTION...MEDIUM TO HIGH CONFIDENCE IN
  WIND SPEEDS.
* LOW TO MEDIUM CONFIDENCE IN PRECIP WEDNESDAY EVENING.

.MARINE...
249 AM CDT

A LOW PRESSURE SYSTEM WILL MOVE EAST INTO SOUTHWEST ONTARIO TODAY
AND WINDS ARE EXPECTED TO QUICKLY RAMP UP IN ADVANCE OF THIS SYSTEM.
BY EARLY AFTERNOON...EXPECT GALES ACROSS LAKE MICHIGAN...PEAKING
THIS EVENING WITH WINDS OF 40 TO 45 KT. A COLD FRONT WILL SWEEP
ACROSS LAKE MICHIGAN OVERNIGHT AND WINDS SHOULD DROP BACK BELOW GALE
FORCE AS THE PRESSURE GRADIENT QUICKLY SLACKENS BEHIND THE FRONT. A
SECONDARY COLD FRONT WILL MOVE ACROSS THE LAKE ON FRIDAY...THOUGH
THE GRADIENT AND RESULTING WINDS ARE EXPECTED TO BE WEAKER WITH
WINDS TOPPING OUT AROUND 30 KT FRIDAY AFTERNOON. BMD
