AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
320 AM CDT MON SEP 17 2012

.DISCUSSION...
320 AM CDT

CONCERNS THIS MORNING REVOLVE AROUND AMPLIFYING TROUGH OVER THE
CENTRAL AND EASTERN CONUS BRINGING SEVERAL CHANCES OF PRECIPITATION
INCLUDING A STRONG COLD FRONT THAT WILL SWEEP ACROSS THE AREA TODAY.

TODAY AND TONIGHT...
A 110KT JET WAS ANALYZED ACROSS ALBERTA THIS MORNING AND IS EXPECTED
TO DIVE SOUTH INTO THE NORTHERN PLAINS TODAY CARVING OUT A BROAD
UPPER TROUGH OVER THE UPPER MIDWEST AND GREAT LAKES REGION BY THIS
EVENING. AT THE SURFACE...A BROAD TROUGH WAS LOCATED FROM WESTERN
IOWA NORTHEAST ACROSS WISCONSIN AND LAKE SUPERIOR. THE BAROCLINIC
ZONE BEHIND THE TROUGH WILL BEGIN TO STRENGTHEN TODAY AS LOW
PRESSURE DEEPENS IN RESPONSE TO THE STRONG WAVE DROPPING OUT OF
CANADA. ALONG AND JUST AHEAD OF THE FRONT...MODELS CONTINUE TO
ADVERTISE 500-1000 J/KG CAPE DEVELOPING WITH 30-40 KT OF DEEP LAYER
SHEAR. SHEAR VECTORS ARE STRONGEST JUST ALONG THE FRONT AS WELL AS
BEHIND THE FRONT...BUT TAPER TO LESS THAN 30 KT NOT TOO FAR AHEAD OF
THE FRONT. GIVEN THESE PARAMETERS...WILL HAVE TO MONITOR FOR
MARGINAL SEVERE THREAT THIS AFTERNOON AND EARLY EVENING. AFTER THE
FRONT PASSES TODAY...EXPECT TEMPERATURES TO QUICKLY FALL WITH A
BRISK NORTHWEST WIND IN PLACE. MIDLEVEL FRONTOGENESIS AND STRONG
HEIGHT FALLS ASSOCIATED WITH THE H5 WAVE WILL BEGIN TO PUSH INTO THE
AREA SUSTAINING THE CHANCES FOR RAIN INTO THE EARLY OVERNIGHT HOURS.

TUESDAY THROUGH TUESDAY NIGHT...
STRONG COLD ADVECTION BEHIND THE COLD FRONT WILL CAUSE H85 TEMPS TO
FALL TO NEAR 2C OVER PORTIONS ON NORTHERN ILLINOIS TUESDAY
AFTERNOON...AND JUST BELOW 0C OVER PORTIONS OF LAKE MICHIGAN.
CONDITIONS CONTINUE TO LOOK FAVORABLE FOR LAKE EFFECT SHOWERS WITH
SFC-850 DELTA T'S GROWING TO 17-18C AND EQUILIBRIUM LEVELS ABOVE 20K
FT. OVER LAND...VERY STRONG LOW TO MID LEVEL LAPSE RATES ARE
EXPECTED AND SHOULD RESULT IN INCREASED CLOUD COVER WITH COLD AIR
STRATOCUMULUS POSSIBLY TAKING ON SOME VERTICAL DEPTH AND PROVIDING
AN OPPORTUNITY FOR A FEW SPRINKLES OR LIGHT SHOWERS. CLOUD COVER
SHOULD DISSIPATE WITH THE LOSS OF DAYTIME HEATING AND SURFACE RIDGE
AXIS BEGINS TO ENCROACH FROM THE WEST. OVERNIGHT...MODELS CONTINUE
TO ADVERTISE FAVORABLE TIMING OF THE RIDGE AXIS FOR STRONG
RADIATIONAL COOLING AND SHOULD EASILY SEE THE COOLEST NIGHT OF THE
SEASON THUS FAR. WE NAY BE FLIRTING WITH RECORD LOW TEMPS. THE
RECORD LOW FOR ROCKFORD FOR SEPTEMBER 19TH IS 34...AND CHICAGO...
WITH THE URBAN HEAT ISLAND...HAS A RECORD LOW OF 40.

WEDNESDAY THROUGH WEDNESDAY NIGHT...
EXPECT TO BE IN BETWEEN SYSTEMS WEDNESDAY AS ANOTHER SHORTWAVE
BEGINS TO DIG ACROSS MINNESOTA TOWARDS THE NORTHERN GREAT LAKES
REGION. SOUTHWESTERLY FLOW INCREASES AHEAD OF THE FRONT AND SHOULD
ALLOW US TO RISE INTO THE UPPER 60S ON WEDNESDAY. LOOKS LIKE MOST OF
THE ENERGY ASSOCIATED WITH THE UPPER LEVEL DISTURBANCE WILL PASS
NORTH OF THE CWA...BUT A TRAILING SURFACE COLD FRONT COULD BRING A
FEW SHOWERS TO THE AREA WEDNESDAY NIGHT.

THURSDAY THROUGH SUNDAY...
EXPECT THE LONGWAVE TROUGH AXIS TO SLOWLY SHIFT TO THE EAST THROUGH
THE PERIOD. SEVERAL MODEST DISTURBANCES ARE FORECASTED TO ROTATE
AROUND THE PERIPHERY OF THE LONGWAVE TROUGH PROVIDING ADDITIONAL
CHANCES FOR PRECIPITATION. TIMING THESE FEATURES IS DIFFICULT THIS
FAR OUT SO WENT WITH A BLEND OF POP GUIDANCE MAINTAINING SOME LOW
CHANCE POPS THROUGH THE PERIOD. AVERAGE TEMPERATURES SHOULD RUN
SEVERAL DEGREES BELOW NORMAL FOR THIS TIME OF YEAR. BMD

//ORD AND MDW CONCERNS...UPDATED 06Z...

* NO CONCERNS THRU 15Z.

* TIMING OF PRECIP...CONVECTIVE CHANCES BEFORE FRONT...AND
  POTENTIAL FOR GUSTY WINDS UP TO 25 KT.

* PSBL MVFR CIGS AFTER THE FRONTAL PASSAGE THRU OVERNIGHT.

BEACHLER

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

NUMEROUS CHALLENGES WITHIN THE CURRENT TAF PERIOD...MAINLY IN THE
15Z MON THRU 03Z TUE TIMEFRAME. IR IMAGERY EARLY THIS MORNING
INDICATES NEAR CLOUDLESS SKIES ACROSS NORTHERN IL/NORTHWEST IN
AIRFIELDS...WHILE SOME CIRRUS WAS APPROACHING FROM THE SOUTH. IN
ADDITION THE APPROACHING WEATHER SYSTEM AND FRONTAL BOUNDARY WAS
BECOMING ACTIVE TO OUR NORTHWEST ACROSS MINNESOTA. PRIOR TO THE
AFOREMENTIONED 15Z PERIOD...VFR CONDS WILL PREVAIL. THEN THE
FRONTAL BOUNDARY WILL BE ON THE DOOR STEPS OF NORTHWEST IL
AIRFIELDS. WITH BETTER MIXING...EXPECT SFC WINDS TO INCREASE WITH
GUSTS IN THE 14 TO 18 KT RANGE FROM THE SOUTHWEST. MOISTURE WILL
STEADILY PUSH OVERHEAD WITH STEADY LOWERING OF CIGS. IT APPEARS
THE PRE-FRONTAL PRECIP COULD BE CONVECTIVE...THUS HAVE OPTED TO
PUSH THIS INTO A VCTS WINDOW. THEN ONCE THE BOUNDARY
ARRIVES...WINDS QUICKLY TURN NORTHWEST AND GUSTS INCREASE
MARGINALLY THRU 03Z TOWARDS 20-24KT. AS WINDS TURN NORTHWEST THE
CONVECTIVE CHANCES WILL END AS STEADY SHRA PSBLY PLAIN RA ARRIVES.
GUIDANCE HAS CONTINUED TO HINT THAT A PERIOD OF MVFR CIGS COULD
DEVELOP AS WELL AS THE STEADY PRECIP PUSHES OVERHEAD. PRECIP SHUD
THEN QUICKLY PUSH EAST ARND 06Z WITH STEADY PUSH OF DRY AIR
ARRIVING FROM THE NORTHWEST. WINDS WILL REMAIN
NORTHWEST...BECOMING GUSTY YET AGAIN TUE MORNING AFT DAYBREAK.
CIGS WILL LINGER ARND LOW END VFR/MVFR.

BEACHLER

//ORD AND MDW CONFIDENCE...UPDATED 06Z...

* HIGH CONFIDENCE IN ALL ELEMENTS THRU 15Z.

* MEDIUM CONFIDENCE IN WIND SPEEDS/GUSTS AFT 15Z THRU 03Z.

* MEDIUM CONFIDENCE IN TIMING OF PRECIP/TSRA.

* HIGH CONFIDENCE IN TSRA ENDING ONCE WINDS TURN NORTHWEST.

.MARINE...

257 PM...FAIRLY ACTIVE PATTERN THIS WEEK WITH SEVERAL FORECAST
CONCERNS. A COLD FRONT EXTENDING FROM LAKE SUPERIOR INTO THE
PLAINS THIS AFTERNOON WILL SLOWLY MOVE SOUTHEAST TONIGHT AND MOVE
ACROSS LAKE MICHIGAN MONDAY AFTERNOON. THE GRADIENT WILL REMAIN
SOMEWHAT TIGHT ACROSS THE NORTHERN HALF TO TWO THIRDS OF THE LAKE
WITH GUSTS TO 30 KTS LIKELY...THOUGH PREVAILING WINDS LIKELY WILL
STAY IN THE 20-25KT RANGE. WINDS WILL QUICKLY SHIFT TO THE
NORTHWEST BEHIND THE FRONT AND NEW LOW PRESSURE IS EXPECTED TO
DEVELOP ALONG THE FRONT OVER NORTHERN LOWER MICHIGAN MONDAY
AFTERNOON. THIS SHOULD HELP TIGHTEN THE GRADIENT BETWEEN HIGH
PRESSURE OVER THE PLAINS AND COMBINED WITH RATHER STRONG COLD AIR
ADVECTION...SHOULD SEE WIND SPEEDS INCREASE TO 30 KTS. SOUNDINGS
OVER THE LAKE DON/T SUGGEST WINDS IN THE LOW LEVELS WILL BE MUCH
HIGHER THEN LOWER 30 KTS...BUT REMAIN CONCERNED FOR THE POTENTIAL
FOR LOW END GALES...ESPECIALLY IF THE LOW DEEPENS MORE THAN
EXPECTED. SO FOR NOW WILL CONTINUE WITH CURRENT GALE GUST MENTION
IN THE GLF TEXT. WIND SPEEDS WILL SLOWLY BEGIN TO DIMINISH TUESDAY
EVENING AS HIGH PRESSURE MOVES ACROSS THE WESTERN LAKES.

A LARGE TROUGH OF LOW PRESSURE WILL DIVE SOUTHEAST OUT OF CANADA
TUESDAY NIGHT INTO WEDNESDAY WITH THE MAIN LOW REMAINING ACROSS
CANADA. HOWEVER...THE GRADIENT WILL TIGHTEN SIGNIFICANTLY BETWEEN
THE DEPARTING HIGH AND THIS APPROACHING TROUGH WEDNESDAY AFTERNOON
AND WEDNESDAY EVENING. DURING THIS TIME...SOUTHERLY WINDS WILL
RAPIDLY INCREASE TO 30 KTS AND DEPENDING ON HOW STRONG OF A
MARINE LAYER EXISTS...ITS POSSIBLE FOR AT LEAST SOME GALE GUSTS TO
35-40 KTS. BUT HAVE SOME TIME TO MONITOR THIS PERIOD AND NO
HEADLINES WITH THIS FORECAST. WINDS WILL SLOWLY DIMINISH FROM
NORTH TO SOUTH THURSDAY MORNING AS A WEAKER COLD FRONT APPROACHES.
