AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
611 PM CST SUN FEB 10 2013

.DISCUSSION...
336 PM CST

FOR THE REMAINDER OF THE AFTERNOON AND TONIGHT...MAIN CONCERN WILL
BE THE BAND OF PCPN PUSHING NORTH AND EAST OF THE AREA THIS
AFTERNOON.  THE MAIN BAND OF PCPN HAS ALREADY MOVED OUT OF THE
CWA...THOUGH SOME LINGERING SHOWERS OR AREAS OF LIGHT RAIN SHOULD
PERSIST INTO THE EVENING AS THE UPPER LOW PUSHES NEWD THROUGH
SOUTHERN MINNESOTA AND INTO CENTRAL WISCONSIN. AT THE SFC...THE MAIN
LOW CENTER SITS IN NWRN IOWA AND HAS DEEPENED TO 990MB.  THE SFC LOW
CENTRAL PRESSURE WILL ACTUALLY CHANGE VERY LITTLE OVER THE NEXT 24
HRS AS IT LIFTS TO LAKE SUPERIOR.  THE EFFECT OF THIS ON THE LOCAL
AREA WILL BE TO MAINTAIN THE WARM...MOIST ADVECTION...WITH SFC TEMPS
AND DEWPOINTS INCREASING THROUGH THE EVENING.  WINDS WILL REMAIN
RATHER BREEZY THROUGH THE NIGHT AS DIRECTION GRADUALLY VEERS FROM
SOUTHERLY TO SOUTHWESTERLY.  ALSO...THERE WILL BE A CHANCE FOR A FEW
ISOLATED SHOWERS INTO THE EVENING...BUT BY AFTER MIDNIGHT
TONIGHT...FLOW WILL TURN NWLY DRAWING SOME COOLER AIR INTO THE
AREA.  THE FAR NWRN PORTIONS OF THE CWA WILL BE SEE THE HIGHER PCPN
CHANCES WITH SOME LIGHT SNOW OR A RAIN/SNOW MIX POSSIBLE THROUGH THE
EARLY MORNING HOURS.

BY TOMORROW...THERE WILL STILL BE A CHANCE FOR SOME LIGHT SNOW OVER
THE NORTHERN PORTIONS OF THE CWA...PERHAPS AS FAR SOUTH AS THE I-80
CORRIDOR.  HOWEVER...ANY ACCUMULATION SHOULD BE LIGHT...ON THE ORDER
OF A COUPLE TENTHS OF AN INCH.  BUT EVEN THIS SNOW WILL BECOME
RATHER DIFFICULT TO MEASURE AS WINDS STEADILY INCREASE THROUGH THE
NIGHT AND TOMORROW.  AS THE MAIN SFC LOW LIFTS THROUGH WISCONSIN TO
LAKE SUPERIOR...STRONG PRESSURE RISES ON THE ORDER OF 6MB/3HRS WILL
TRAIL THE LOW.  ALSO...THE LATEST MODEL SOUNDINGS INDICATE A RAPID
INCREASE IN WIND SPEED WITH HEIGHT.  BY TOMORROW MORNING...WINDS AT
THE TOP OF THE MIXED LAYER WILL APPROACH 50KT.  HOWEVER...THERE
SHOULD BE CONSIDERABLE CLOUD COVER...SO WITHOUT ADEQUATE
SUNSHINE...DO NOT ANTICIPATE THAT WINDS THIS STRONG WILL BE ABLE TO
MIX DOWN TO THE SFC.  AT THIS POINT...SUSTAINED WINDS OF 25 TO 30
MPH ARE LIKELY WITH FREQUENT GUSTS IN EXCESS OF 40 MPH ARE
POSSIBLE...WHICH IS VERY CLOSE TO WIND ADVISORY CRITERIA.  SHOULD
LATER ANALYSIS AND MODEL RUNS INDICATE THAT STRONGER WINDS MAY MIX
DOWN TO THE SURFACE...A WIND ADVISORY MAY BE REQUIRED.

WITH A VERY PROGRESSIVE PATTERN SETTING UP OVER THE CONUS...THE
WEATHER WILL BE RATHER CHANGEABLE OVER THE NEXT SEVERAL DAYS.  BY
TUESDAY...CONDITIONS WILL QUIET CONSIDERABLY WITH WINDS DROPPING OFF
OVERNIGHT MONDAY NIGHT WHILE SKIES PARTIALLY CLEAR.  A WEAK
SHORTWAVE IS EXPECTED TO DROP OUT OF CANADA AND TRACK ACROSS THE
UPPER GREAT LAKES...BUT IT WILL BE TOO FAR NORTH TO HAVE ANY IMPACT
ON THE LOCAL WEATHER.  WITH INCREASING SUNSHINE AND DECREASING
WINDS...TEMPERATURES SHOULD RANGE FROM THE LOWER 30S NEAR THE
WISCONSIN BORDER TO THE UPPER 30S SOUTH OF THE I-80 CORRIDOR.
WEDNESDAY SHOULD BE QUIET AS WELL WITH TEMPERATURES REACHING EVEN
HIGHER ;EVE;S WITH HIGHS IN THE UPPER 30S TO THE NORTH AND THE LOWER
TO MIDDLE 40S OVER THE SOUTHERN PORTIONS OF THE CWA.

THE NEXT WEATHER FEATURE OF CONCERN WILL BE A NORTHERN STREAM SYSTEM
DROPPING THROUGH THE NORTHERN PLAINS AND UPPER MISSISSIPPI VALLEY
WEDNESDAY NIGHT INTO THURSDAY MORNING.  THERE IS SOME DISAGREEMENT
AMONG THE MODELS ON HOW FAR SOUTH THE SYSTEM WILL DIG...AND THE
TRACK OF THIS SYSTEM WILL HAVE A MAJOR IMPACT ON THE LOCAL WEATHER.
WHILE THE GFS IS A LITTLE STRONGER AND FASTER THAN THE ECMWF...BOTH
OF THESE MODELS ARE TRENDING ON KEEPING THE STRONGEST MID LEVEL
FORCING OVER WISCONSIN.  THE SFC PROGS INDICATE A SIMILAR TREND...SO
EXPECT THE HIGHEST PCPN CHANCES TO BE NORTH OF THE WISCONSIN
BORDER...BUT A WEAK TRAILING COLD FRONT TRACKING THROUGH NRN IL/NWRN
IN COULD PROVIDE ENOUGH FORCING TO JUSTIFY KEEPING LOW POPS AT LEAST
OVER THE NORTHERN PORTIONS OF THE CWA.

FOR THE LONGER TERM...FROM FRIDAY THROUGH SUNDAY...THE GENERAL TREND
FOR A DEEP LONGWAVE UPPER TROUGH TO CARVE OUT OVER THE ERN CONUS
WITH STRONG RIDGING BUILDING OVER THE WRN CONUS. THE LAST TIME THIS
TYPE OF PATTERN DEVELOPED...THE LOCAL AREA WAS STUCK UNDER
PERSISTENT NWLY FLOW ALOFT AND A SERIES OF WEAK CLIPPERS...DUE TO A
BLOCKY PATTERN WITH LITTLE PROGRESSION.  FORTUNATELY...THIS DOES NOT
LOOK TO BE THE CASE THIS TIME AS THE LONGER RANGE MODEL GUIDANCE IS
SUGGESTING THAT THE PATTERN WILL REMAIN PROGRESSIVE THROUGH THE
PERIOD AND THE UPPER TROUGH WILL QUICKLY PUSH OFF TO THE EAST WITH
LOW AMPLITUDE RIDGING BUILDING OVER THE CNTRL CONUS BY NEXT
WEEKEND.  SO...THROUGH THE LONGER RANGE FORECAST PERIOD...EXPECT
PERIODIC CHANCES FOR SOME PCPN WITH TEMPERATURES A LITTLE ABOVE
SEASONAL NORMAL LEVELS.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 00Z...

* PERIOD OF IFR VIS/CIG IN -RA/BR EARLY THIS EVENING...VIS
  IMPROVING QUICKLY TO VFR BY MID-EVE WITH CIGS A LITTLE SLOWER TO
  IMPROVE TO MVFR BY LATE EVE.

* MVFR CIGS MAY BRIEFLY BECOME VFR LATE EVENING/EARLY OVERNIGHT...
  THOUGH MVFR CIGS IN THE 2000-3000 FT RANGE EXPECTED TO PREVAIL
  THROUGH MUCH OF MONDAY.

* GUSTY WINDS FROM THE SOUTH AT 25-30 KT THIS EVE...THEN BECOMING
  WSW WITH GUSTS 35-40 KT AFTER ABOUT 08Z TONIGHT. WINDS THEN
  REMAIN QUITE GUSTY AND GRADUALLY BECOME MORE WEST MONDAY.

* SNOW SHOWERS MONDAY...WITH POTENTIAL TO PRODUCE BRIEF LOCALIZED
  IFR CONDITIONS.

RATZER

//DISCUSSION...UPDATED 00Z...

DEEP LOW PRESSURE WAS MOVING NORTHEAST FROM NORTHWEST IOWA INTO
SOUTHERN MINNESOTA EARLY THIS EVENING...WITH AN OCCLUDED COLD FRONT
EXTENDING SOUTHEAST INTO WESTERN IL. GUSTY SOUTH WINDS AHEAD OF
THIS FRONT WERE PULLING WARM/MOIST AIR NORTHWARD ACROSS MUCH OF IL
AND THE TERMINALS...WITH A RIBBON OF IFR CIG/VIS CONDITIONS IN FOG
AND LIGHT RAIN/DRIZZLE WITHIN THIS AXIS OF WARM/MOIST ADVECTION
CURRENTLY WORKING ACROSS THE FORECAST AREA. LOCAL RADAR INDICATES
MUCH OF THE LIGHT PRECIPITATION SHOULD QUICKLY MOVE EAST OF THE
TAF SITES...ALLOWING VISIBILITY TO IMPROVE QUICKLY OVER THE NEXT
1-2 HOURS WHILE IFR CIGS ARE EXPECTED TO LINGER AHEAD OF THE
FRONT. THE FRONT...WHICH WAS OVER WESTERN IL AT 00Z...SHOULD
CONTINUE TO PUSH TO THE EAST-NORTHEAST THIS EVENING AND WILL MOVE
ACROSS THE TERMINAL SITES IN THE 03-05Z TIME FRAME. THIS SHOULD
ALLOW CIGS TO ALSO IMPROVE WELL INTO MVFR RANGE OR EVEN VFR AT
LEAST TEMPORARILY DURING THE LATE EVENING/MIDNIGHT HOURS.

MVFR CIGS ARE THEN EXPECTED TO SPREAD BACK INTO THE REGION LATER
TONIGHT AS COLDER AIR WRAPS EASTWARD AROUND THE UPPER MIDWEST LOW.
THIS IS ALREADY OCCURRING ACROSS WESTERN/CENTRAL IA. PERSISTENT
LOW LEVEL COLD ADVECTION AND CYCLONIC FLOW SHOULD HELP TO MAINTAIN
MVFR CIGS RIGHT THROUGH MONDAY...WITH SCATTERED SNOW SHOWERS
LIKELY DEVELOPING ACROSS WI/NORTHERN IL DURING THE DAY AS UPPER
TROUGH MOVES OVER/JUST NORTH OF THE FORECAST AREA. MUCH OF THE
STATISTICAL MODEL GUIDANCE PROGS CIGS IN THE 2000-3000 FT RANGE...
THOUGH SURFACE OBS DO INDICATE SOME 1000-1500 FT CIGS CURRENTLY
WITH ACTIVITY ACROSS WESTERN IA. HAVE TRENDED DOWN A BIT INTO THE
2500 FT RANGE FROM EARLIER TAFS...AND THIS SEEMS REASONABLE FOR
NOW AS NORTHERN IL/NORTHWEST IN WILL BE ON THE SOUTHERN PERIPHERY
OF THE BETTER MOISTURE/UPPER FORCING WITH THE LOW MOVING TO OUR
NORTH. DRYER LOW LEVELS FROM HERE SOUTH DOES RAISE QUESTIONS AS TO
COVERAGE OF ANY SHSN...WHICH SHOULD BE MORE COMMON ACROSS WI.
CONFIDENCE FAIRLY LOW ON TIMING/COVERAGE OF THESE AND THEIR VIS
IMPACTS AT THIS TIME.

THE STRONG PRESSURE GRADIENT ASSOCIATED WITH THE DEEP SURFACE LOW
IS ALREADY PRODUCING SOUTH WINDS GUSTING NEAR 30 KTS ACROSS THE
TERMINALS THIS EVENING. AS THE LOW TRACKS NORTH OF THE FORECAST
AREA THROUGH MONDAY...WINDS WILL SHIFT MORE SOUTHWEST TONIGHT AND
EVENTUALLY TO THE WEST OR WEST-SOUTHWEST MONDAY. DEEPENING OF THE
MIXED LAYER LATE TONIGHT...BEYOND ABOUT 08Z PER GUIDANCE
SOUNDINGS...SUPPORTS EVEN STRONGER WIND GUSTS IN THE 35-40 KT
RANGE. WEST WINDS WILL VERY GRADUALLY DECREASE LATE MONDAY AS THE
LOW MOVES NORTHEAST INTO CANADA AND SLOWLY FILLS/WEAKENS.

RATZER

//ORD AND MDW CONFIDENCE...UPDATED 00Z...

* HIGH CONFIDENCE IN TREND OF IFR CIGS/VIS IMPROVING TO MVFR THIS
  EVENING...AND CIGS TO VFR.

* MEDIUM-HIGH CONFIDENCE IN PREVAILING MVFR CIGS THROUGH MONDAY.

* HIGH CONFIDENCE IN WIND TRENDS THROUGH PERIOD...THOUGH MEDIUM
  CONFIDENCE IN DETAILS OF GUST SPEEDS LATE TONIGHT/MONDAY.

.MARINE...
219 PM CST

MAIN CONCERNS THIS AFTERNOON WILL BE DEALING WITH A COUPLE
PERIODS OF GALES IN THE NEAR TERM. THIS AFTERNOON...LOW PRESSURE
IS DEEPENING AND LIFTING NORTHEAST ACROSS THE PLAINS TOWARDS THE
WESTERN GREAT LAKES REGION. THIS HAS ALLOWED SOUTH-SOUTHEAST WINDS
TO INCREASE...AND IS EXPECTED TO PEAK THIS AFTERNOON AROUND 30 KTS
AT THE SURFACE. DUE TO A STABLE MARINE LAYER...MUCH STRONGER WINDS
ALOFT WILL NOT BE ABLE TO MIX TO THE SURFACE...HOWEVER STILL THINK
A FEW GALE FORCE GUSTS ARE POSSIBLE LATE THIS AFTERNOON AND EARLY
EVENING MAINLY ACROSS THE SOUTHERN HALF TO TWO THIRDS OF THE LAKE.
AS THE LOW CROSSES THE LAKE LATE TONIGHT INTO EARLY MONDAY...WINDS
WILL VEER TO THE WEST AND COLD ADVECTION WILL ALLOW MIXING TO
INCREASE OVER THE LAKE. 40 AND OCCASIONALLY 45 KT GUSTS WILL BE
POSSIBLE FOR THE SOUTHERN TWO THIRDS OF THE LAKE...HOWEVER THE FAR
NORTH SECTIONS OF THE LAKE MAY BE SPARED GALES AS THE GRADIENT IS
WEAKER CLOSER TO THE LOW. SHOULD BE RELATIVELY QUIET THROUGH
MIDWEEK ACROSS THE LAKE...THEN NEXT CONCERN WILL BE A LOW MOVING
ACROSS THE LAKE THURSDAY INTO FRIDAY. GUIDANCE CURRENTLY MIXED ON
HOW STRONG/ORGANIZED THIS SYSTEM WILL...SO DIFFICULT TO PIN DOWN
HOW STRONG WINDS WILL BE AND THE POTENTIAL FOR GALES THIS FAR
OUT...BUT CERTAINLY THEY ARE WITHIN THE REALM OF POSSIBILITY. BMD
