AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
341 PM CDT FRI SEP 20 2013

.DISCUSSION...
341 PM CDT

THE COLD FRONT CONTINUES TO STRUGGLE TO MAKE A SIGNIFICANT EASTWARD
PUSH ACROSS THE REGION THIS AFTERNOON...SLOW BUT SURE IS THE NAME OF
THE GAME.

THE UPPER PATTERN FROM THE EASTERN PACIFIC ACROSS NOAM TO THE
WESTERN ATLANTIC IS HIGHLY AMPLIFIED AND SLOWLY PROGRESSIVE. AT
EARLY AFTERNOON AN UPPER TROUGH EXTENDS SOUTHWARD ACROSS WESTERN
ONTARIO AND THEN SOUTHWESTWARD ACROSS THE UPPER MS AND MID MO
VALLEYS...TO THE PLAINS OF EASTERN CO AND WESTERN. A COMPACT...
SHEARED UPPER CIRCULATION THAT WAS NORTH OF LAKE WINNIPEG THIS
MORNING HAS QUICKLY DROPPED SOUTHWARD TO OVER THE SD-MN BOARDER...
STARTING TO TURN SOUTH-SOUTHEASTWARD AS IT APPROACHES THE TROUGH
AXIS.

MODELS ARE SIMILAR IN THEIR SOLUTIONS IN TAKING THIS DISTURBANCE
SOUTHEASTWARD TO SOUTHEASTERN MN AT 21.00Z THEN EAST-SOUTHEASTWARD
TO SOUTHERN WI AT 21.06Z AND THEN LIFTING NORTHEASTWARD AND
NORTH-NORTHEASTWARD OUT OF THE TROUGH AXIS TO NORTHERN LOWER MI BY
21.12Z. WITH THE DISTURBANCE NEARING THE UPPER TROUGH AXIS LATE THIS
AFTERNOON AND EARLY THIS EVENING AND THEN ROTATING THROUGH IT LATE
TONIGHT AND OVERNIGHT THE UPPER TROUGH IS ACCELERATE EASTWARD...
WHICH IN TURN ALLOWS THE COLD FRONT TO START ACCELERATING ALSO WITH
IT PROGGED TO FINALLY CLEAR THE NORTHWEST IN COUNTIES OF THE
FORECAST AREA MID TO LATE EVENING.

ISOLATED SMALL SHOWERS CONTINUED SOUTHEAST OF A KOUTS TO MOROCCO TO
WATSEKA TO PAXTON LINE AND EXPECT THESE NUISANCE SHOWERS TO PERSIST
INTO THIS EVENING UNTIL THE UPPER TROUGH AND THE COLD FRONT START
PUSHING A BIT FURTHER EASTWARD. THE CONTINUED PROGRESSION OF THE
UPPER TROUGH TONIGHT WILL CLEAR OUT THE REMAINING STRATOCUMULUS
ACROSS THE FAR SOUTHEASTERN PORTION OF THE FORECAST AREA AND ALSO
LEAD TO THE CONTINUED THINNING OF THE CIRRUS ASSOCIATED WITH THE
STRONG UPPER JET UP THE FRONT SIDE OF THE UPPER TROUGH AS IT MOVES
EASTWARD FROM ITS CURRENT OVERHEAD LOCATION.

AS THE CORE OF THE VERY COOL AIR SETTLED OVER THE UPPER MIDWEST
TODAY IT BROUGHT A BROKEN DECK OF STRATOCUMULUS SOUTHEASTWARD WITH IT
AND HAD REACHED SOUTHEASTERN WI AND EAST CENTRAL IA AT MID
AFTERNOON. THE COOL AIR WILL SPREAD ACROSS WI...NORTHERN IL AND
NORTHWESTERN IN TONIGHT THOUGH THE CORE OF THE COLD AIR WILL PUSH
MORE EASTWARD INTO THE GREAT LAKES AS THE UPPER TROUGH ACCELERATES
EASTWARD TONIGHT. STILL...EXPECT TO SEE SOME OF THIS STRATOCUMULUS
OVERSPREAD THE FORECAST AREA LATE TONIGHT.

THE WEEKEND AND EARLY NEXT WEEK WILL BE DOMINATED BY COOL HIGH
PRESSURE AS IT GRADUALLY BUILDS OUT OF CENTRAL CANADA AND OVER THE
GREAT LAKES...AND THE UPPER RIDGE...CURRENTLY EXTENDING NORTHWARD
OVER THE CENTRAL ROCKIES ALL THE WAY UP ACROSS THE NORTHWEST..AS IT
GRADUALLY PROGRESSES EASTWARD ACROSS THE PLAINS TO THE GREAT
LAKES...MS VALLEY AND OH VALLEY.

BY 24.12Z...TUESDAY MORNING...THE MODELS HAVE STARTED TO DEVIATE ON
HOW STRONG AND FAST THE UPPER LOW CURRENTLY OVER THE EASTERN PACIFIC
IS AFTER COMING ASHORE AND TRACKING NORTHEASTWARD ACROSS THE
ROCKIES AND PLAINS. WHILE CONSISTENT WITH ITS PREVIOUS RUN THE ECMWF
IS MUCH STRONGER/DEEPER...AND AS A RESULT SLOWER...WITH THE
SYSTEM AS IT MOVES ACROSS THE MID AND UPPER MS VALLEY AND THE UPPER
MIDWEST. BOTTOM LINE IS THAT EVEN IF THIS STRONGER SOLUTION VERIFIES
THE SYSTEM WILL HAVE LITTLE IF ANY MOISTURE TO WORK WITH AS THE
LARGE SURFACE ANTICYCLONE TO THE EAST CONTINUES TO FEED DRY AIR
WESTWARD AND NORTHWESTWARD TO THE AREA.

WITH SOLUTIONS BY DAY 7...FRIDAY THE 27TH...MODELS VARY
SIGNIFICANTLY ON PLACEMENT OF AND UPPER LOW/TROUGH FROM CENTRAL
CANADA SOUTHWESTWARD ACROSS THE ROCKIES. CONSENSUS FORECAST BRINGS A
CHANCE OF RAIN TO THE REGION BY THEN THOUGH GIVEN LOW CONFIDENCE IN
MODEL SOLUTIONS HAVE ONLY LOW END CHANCE POPS IN THE FORECAST.

TEMPERATURES WILL RUN BELOW NORMALS THROUGH THE EARLY PART OF THE
WORK WEEK BEFORE MODERATION TO AROUND NORMAL TUESDAY AND THEN
WARMING TO WELL ABOVE NORMALS BY LATER IN THE WORK WEEK STRONG
SOUTH-SOUTHWEST LOW LEVEL FLOW SPREADS FROM THE SOUTHERN PLAINS TO
THE UPPER MIDWEST AND WESTERN GREAT LAKES.

.AVIATION...

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

* WEST WINDS ARND 10-14KT WITH GUSTS ARND 16-19KT THRU 00Z.
* WINDS SLOWLY TURNING NW/N AFT 23Z.

BEACHLER

//DISCUSSION...UPDATED 18Z...

FRONTAL BOUNDARY STRETCHES FROM GYY SOUTH THROUGH IKK AT 18Z.
WIND SHIFT TO THE WEST BEHIND THIS BNDRY. VISIBLE IMAGERY
CONTINUES TO INDICATE CONSIDERABLE CLOUDS WITH CIGS SLOW TO
IMPROVE...HOWEVER THEY HAVE COME UP TO ARND 1800-2000FT AGL. SKIES
ARE THINNING FURTHER BEHIND THE BOUNDARY...AND EXPECT THAT WITH
ADDTL HEATING THIS WILL ALLOW INCREASED WIND SPEEDS/GUSTS TO
20-24KT AND WILL HELP TO LIFT CIGS FURTHER. EXPECT CLOUDS TO
LINGER ARND 3-4KFT AGL THRU SUNSET THEN SLOWLY ERODE AFT 03Z. BY
08-10Z SKIES SHOULD ALMOST BECOME CLEAR WITH JUST A CIRRUS SHIELD
OVERHEAD. WINDS WILL CONTINUE TO TURN NORTH/NORTHWEST. AFT 16Z SAT
WINDS WILL BEGIN TO INCREASE YET AGAIN FROM THE NORTH/NORTHWEST
WITH GUSTS IN THE MID TO UPPER TEENS THRU MUCH OF MIDDAY AND
AFTERNOON HOURS. A SCT DECK OF CLOUDS SHOULD DEVELOP BY 18Z AND
MAY FOR A PERIOD OF TIME BECOME BKN EARLY IN THE AFTN. OTHERWISE
EXPECT IT TO REMAIN SCT WITH BASES ARND 3KFT AGL.

BEACHLER

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

* HIGH CONFIDENCE IN CIGS SLOWLY LIFTING THROUGHOUT THE LATE AFTN/EVE.

* HIGH CONFIDENCE IN WIND DIR/SPEED/GUSTS.

* MEDIUM/HIGH CONFIDENCE IN TIMING OF WINDS TURNING NW/N.

BEACHLER

//OUTLOOK FOR ORD/MDW FOR 00Z SUNDAY-12Z FRIDAY...UPDATED 12Z...

* SATURDAY NIGHT...MVFR CIGS POSSIBLE.
* SUNDAY THROUGH THURSDAY...DRY/VFR.

&&

.MARINE...
322 PM CDT

A STRONG COLD FRONT CLEARING THE LAKE LATE THIS AFTERNOON WILL
RESULT IN A PERIOD OF NORTH/NORTHWEST WINDS TO 25 KT INTO SATURDAY
AFTERNOON. SUPPORT IS NOT AS STRONG FOR 30 KT WINDS THIS
EVENING/TONIGHT...BUT OCCASIONAL 30 KT GUSTS REMAIN
POSSIBLE...ESPECIALLY ON THE SOUTH HALF THROUGH LATE TONIGHT. AN
UPPER TROUGH PASSAGE OVER THE NORTHERN LAKES REGION BY EARLY
SATURDAY EVENING WILL RESULT IN A SURGE OF VERY COLD AIR FOR
SEPTEMBER WITH 4000 FT TEMPS DIPPING BELOW 0C OVER THE NORTH HALF
OF LAKE MICHIGAN. THEREFORE...DESPITE HIGH PRESSURE BUILDING IN
FROM THE NORTH...HAVE INCREASED WINDS ON THE NORTH HALF TO 30 KT
FOR A PERIOD SATURDAY EVENING. HAVE SOME CONCERN THAT THE MODEL
GUIDANCE IS UNDERDOING WINDS A BIT AND EVEN A FEW GALE FORCE GUSTS
ARE POSSIBLE. THE COLD SURGE WILL NOT MAKE IT ALL THE WAY DOWN THE
LAKE...BUT WINDS SHOULD STILL REMAIN ELEVATED IN THE 15 TO 25 KT
RANGE ON THE SOUTH HALF SATURDAY NIGHT. HIGH PRESSURE WILL BUILD
OVER THE LAKE BY SUNDAY AFTERNOON...CAUSING WINDS TO DIMINISH.
HIGH PRESSURE WILL THEN SLIDE SLOWLY EASTWARD THROUGH MID NEXT
WEEK...RESULTING IN A PROLONGED PERIOD OF MODEST SOUTHERLY FLOW.

HAVE ISSUED A SMALL CRAFT ADVISORY FROM GARY TO MICHIGAN CITY LATE
TONIGHT THROUGH LATE SATURDAY NIGHT PRIMARILY FOR WAVES BUILDING TO
UP TO 6 FT BEFORE SUBSIDING BY EARLY SUNDAY.
