AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
646 AM CDT TUE APR 9 2013

.DISCUSSION...
335 AM CDT

FORECAST CHALLENGES THIS MORNING INCLUDE TIMING BEST CHANCES FOR
THUNDERSTORMS AND RAINFALL THE NEXT 72 HOURS...INCLUDING THE
POTENTIAL FOR SEVERE THUNDERSTORMS. EQUALLY AS CHALLENGING THIS
MORNING WILL BE TRYING TO REPRESENT THE VERY STRONG FRONT AND
CORRESPONDING TEMP GRADIENT IN THE GRIDS THROUGH MID WEEK.

WATER VAPOR IMAGERY THIS MORNING SHOWED GORGEOUS UPPER TROUGH OVER
THE ROCKY MOUNTAINS WITH ASSOCIATED SFC LOW ORGANIZING OVER THE
CENTRAL HIGH PLAINS. VERY SHARP QUASI-STATIONARY EAST-WEST FRONT
EXTENDS FROM THIS LOW ACROSS IOWA INTO NORTHERN/CENTRAL ILLINOIS.
APPROXIMATELY A 25F GRADIENT BETWEEN THE LAKE COOLED AIR TO THE
NORTH OF THE FRONT AND THE VERY WARM AND HUMID AIR MASS RESIDING TO
ITS SOUTH. FRONT IS PROGGED TO LIFT NORTHWARD TODAY LIKELY REACHING
AT LEAST THE I-80 CORRIDOR...AND POSSIBLY AS FAR NORTH AS THE 88/290
CORRIDOR. NEAR THE LAKE TO THE NORTH OF THE FRONT TEMPS WILL
STRUGGLE TO GET INTO THE 40S WITH TEMPS LIKELY TO SOAR WELL INTO THE
70S SOUTH OF THE BOUNDARY. THE TIGHT TEMP GRADIENT WILL LEAD TO A
HIGH BUST POTENTIAL FOR TEMPS TODAY.

BAND OF SCTD ELEVATED STORM LIFTING NORTH ACROSS THE AREA EARLY THIS
MORNING SEEM TO BE ROUGHLY ALIGNED WITH THE 850MB WARM FRONT WHICH
MODELS ALL SUGGEST WILL BLAST NORTH INTO WI THIS MORNING...LIKELY
TAKING THE BETTER THUNDERSTORM CHANCES WITH IT. SURFACE WARM FRONT
LIKELY TO STALL OUT OVER CWA AND WILL NEED TO MONITOR FOR POSSIBLE
SURFACE BASED CONVECTION FIRING ALONG THIS BOUNDARY THIS AFTERNOON.
MODELS DO SHOW A WEAK SOUTHERN STREAM SHORTWAVE LIFTING NORTH FROM
THE SOUTHERN PLAINS INTO THE MID-MS RIVER VALLEY THIS
AFTERNOON...THOUGH REALLY HARD TO PICK OUT THIS WAVE ON WATER VAPOR
IMAGERY. WHILE CHANCES DON'T LOOK OVERLY HIGH...SHOULD SFC BASED
CONVECTION POP THIS AFTERNOON ALONG OR JUST SOUTH OF THE WARM FRONT
THEN THERE WOULD BE A CORRESPONDING THREAT OF SEVERE STORMS GIVEN
THE MODERATELY STRONG DEEP LAYER SHEAR AND PROGGED MODERATE
INSTABILITY. GIVEN THE FORECAST BUNKERS STORM MOTION PARALLEL TO THE
SFC BOUNDARY REALLY CAN'T RULE OUT A SUPERCELL OR EVEN SMALL
CONDITIONAL TORNADO RISK FOR ANY ESTABLISHED STORM THAT CAN CLING TO
THE FRONT. CONFIDENCE IN STORMS DEVELOPING IS NOT HIGH SO NOT
PLANNING TO HIT THIS THREAT OVERLY HARD IN THE HWO...BUT IT
SOMETHING THAT WILL NEED TO BE CLOSELY MONITORED TODAY. ADDITIONAL
ELEVATED CONVECTION COULD DEVELOP NORTH OF THE FRONT TODAY...BUT
WITH FRONT JUST OFF THE SURFACE PROGGED TO LIFT NORTH INTO WI THINK
THE BETTER THREAT OF ORGANIZED CONVECTION WILL REMAIN NORTH OF OUR
CWA AND HAVE TRIED TO REFLECT THIS WITH SOMEWHAT LOWER POPS TODAY.

DOES APPEAR TO BE AN MCV FORMING WITH THE MCS ONGOING OVER NEBRASKA
THIS MORNING...BUT GUIDANCE WOULD SUGGEST THAT THIS FEATURE WOULD
TEND TO PROPAGATE A BIT NORTH OF DUE EAST WITH TIME AND PROBABLY
AFFECTING OUR FAR NORTHERN CWA OR POINTS EVEN FARTHER NORTH LATE
THIS AFTERNOON INTO THIS EVENING. COULD BE A LULL IN PRECIP CHANCES
MUCH OF TONIGHT...ESPECIALLY SOUTHERN HALF OF THE CWA BEFORE
REMNANT PLAINS CONVECTION BEGINS TO THREATEN THE CWA LATE TONIGHT.
PERIODS OF SHOWERS AND THUNDERSTORMS WILL CONTINUE WEDNESDAY INTO
WEDNESDAY NIGHT AS THE ENTIRE UPPER TROUGH MOVES EASTWARD TOWARD THE
REGION. SOME SEVERE THREAT COULD EXIST WEDNESDAY DEPENDING ON THE
EVOLUTION OF PRIOR DAY'S CONVECTION...WITH THE GREATEST SEVERE
THREAT SOUTH OF WHERE EVER THE WARM FRONT SETS UP BUT EVEN TO THE
NORTH OF THE FRONT SOME RISK FOR ELEVATED HAILERS EXISTS. LOOKING
INCREASINGLY LIKELY THAT WE WILL MISS THE HEAVIEST RAINFALL TODAY
AND TONIGHT...SO WITH THREAT OF HEAVY RAINFALL DELAYED UNTIL
WEDNESDAY INTO WEDNESDAY NIGHT DID NOT SEE A NEED FOR A FLOOD WATCH
AT THIS TIME..BUT WITH POTENTIAL FOR SEVERAL RIVER FORECAST POINTS
TO RISE INTO FLOOD WITH WORST CASE SCENARIOS WILL ISSUE AN ESF.

UPPER LOW WILL MOVE SLOWLY EASTWARD WITH SHOWERS LIKELY LINGERING
INTO THURSDAY AND POSSIBLY EVEN THURSDAY NIGHT. ITS POSSIBLE THAT
AIR MASS COULD GET COLD ENOUGH FOR A CHANGE OVER TO SOME SNOW
SHOWERS THURSDAY NIGHT...ESPECIALLY NORTHWEST CWA...BUT AT THIS
POINT IT LOOKS LIKE ANY SNOW WOULD MELT AND NOT ACCUMULATE POSING
ANY PROBLEMS.  SYSTEM LOOKS TO SLOWLY PULL EAST OF THE REGION BY
WEEK'S END WITH UNSEASONABLY COLD WEATHER GIVING WAY TO A QUICK WARM
UP OVER THE WEEKEND. DUE TO THE VERY BUSY CURRENT AND UPCOMING
WEATHER THE NEXT FEW DAYS...HAD NO TIME TO LOOK AT THE EXTENDED
FORECAST OR MAKE ANY CHANGES TO THAT TIME PERIOD.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 12Z...

* IFR/LIFR CIGS THROUGH THE PERIOD.
* CHANCE OF SHOWERS THIS MORNING. CHANCE OF SHOWERS...POSSIBLY
  TSRA THIS AFTERNOON AND SHOWERS AND THUNDERSTORMS WEDNESDAY
  MORNING. CMS

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

SCATTERED SHOWERS CONTINUE TO DEVELOP FROM THE QUAD CITIES
SOUTHEAST ACROSS CENTRAL IL. THESE SHOWERS WILL SPREAD ACROSS THE
TERMINALS OVER THE NEXT FEW HOURS AND THEN EXPECT DRY CONDITIONS
INTO EARLY THIS AFTERNOON. AS A WARM FRONTAL BOUNDARY LIFTS NORTH
TO ROUGHLY THE I-80 CORRIDOR AND AN UPPER LEVEL WAVE MOVES
NORTHEAST ACROSS THE AREA THIS AFTERNOON...ISOLATED/SCATTERED
THUNDERSTORMS ARE POSSIBLE BUT CONFIDENCE REGARDING COVERAGE AND
LOCATION IS LOW. HAVE CONTINUED VCSH MENTION THIS AFTERNOON EXCEPT
AT GYY...WHERE VCTS MENTION CONTINUES. ANY ACTIVITY THAT DOES
DEVELOP SHOULD BE SHIFTING EAST AND WEAKENING BY/TOWARD SUNSET.
THIS EVENING INTO THE EARLY MORNING HOURS APPEARS DRY WITH ANOTHER
WAVE OF SHOWERS/THUNDERSTORMS MOVING ACROSS THE REGION IN THE
PREDAWN HOURS/WEDNESDAY MORNING.

LIFR CIGS EXPECTED TO PERSIST THIS MORNING BUT CONFIDENCE THEN
DECREASES THIS AFTERNOON. AS THE FRONTAL BOUNDARY LIFTS NORTH TO
NEAR GYY...POSSIBLY MDW...LOW CLOUDS WILL LIKELY SCATTER OUT WITH
PREVAILING VFR POSSIBLE. HOW FAR NORTH LOW CLOUDS SCATTER IS
UNCERTAIN AND AT THIS POINT HAVE MAINTAINED BKN CIGS AT ORD...
POSSIBLY LIFTING TO 1KFT OR BETTER BY EARLY AFTERNOON BUT TRENDS
WILL NEED TO BE MONITORED FOR ADDITIONAL IMPROVEMENT. THE FRONT
SAGS BACK SOUTH THIS EVENING AND AS THE COLDER AIR OVER THE LAKE
SPREADS BACK INLAND...CIGS LIKELY TO LOWER BACK INTO IFR/LIFR. CMS

//ORD AND MDW CONFIDENCE...UPDATED 12Z...

* MEDIUM CONFIDENCE REGARDING CIG TRENDS THIS MORNING...LOW
  CONFIDENCE FOR THE REST OF THE PERIOD.
* MEDIUM CONFIDENCE REGARDING PRECIP TRENDS THIS MORNING...LOW
  CONFIDENCE FOR THE REST OF THE PERIOD. CMS

.MARINE...

312 AM...A FRONTAL BOUNDARY WILL REMAIN NEARLY STATIONARY THROUGH
THURSDAY MORNING OVER FAR SOUTHERN LAKE MICHIGAN...OR JUST SOUTH
OF THE LAKE. AS THIS BOUNDARY DRIFTS NORTH AND SOUTH...WIND
CHANGES FROM NORTH TO SOUTH ARE POSSIBLE...IN ADDITION TO PERIODS
OF LIGHT AND VARIABLE WINDS. WITH THE COLDER AIR OVER THE LAKE
INTERACTING WITH THE WARM MOIST AIR SOUTH OF THIS FRONT...DENSE
FOG CAN ALSO BE EXPECTED. TIMING AND LOCATION OF THE DENSE FOG
ADVISORY WILL NEED SOME REFINEMENT LATER TODAY. NORTH/NORTHEAST
WINDS WILL INCREASE TODAY...NORTH OF THIS BOUNDARY AND EXPECT 30
KTS ACROSS NORTH CENTRAL PORTIONS OF THE LAKE. THESE HIGHER WINDS
WILL SPREAD FURTHER SOUTH TONIGHT. LOW PRESSURE OVER THE SOUTHERN
PLAINS WILL MOVE NORTHEAST ALONG THE FRONTAL BOUNDARY WEDNESDAY
REACHING CENTRAL ILLINOIS WEDNESDAY NIGHT OR THURSDAY MORNING. AS
THIS LOW APPROACHES...THE GRADIENT WILL TIGHTEN FURTHER AND STILL
APPEARS A PERIOD OF LOW END GALES IS POSSIBLE LATE WEDNESDAY NIGHT
INTO THURSDAY AND IF THESE TRENDS CONTINUE...HEADLINES WILL LIKELY
BE NEEDED LATER TODAY. THE LOW MAY SLOW AS IT MOVES NORTHEAST OVER
THE EASTERN GREAT LAKES THURSDAY NIGHT INTO FRIDAY. SHOULD THIS
OCCUR...WINDS MAY BE SLOWER TO DIMINISH BUT EVENTUALLY A RIDGE OF
HIGH PRESSURE WILL MOVE ACROSS THE LAKES FRIDAY NIGHT INTO
SATURDAY. CMS

  WEATHER HAZARDS EXPECTED:

  DENSE FOG.

  THUNDERSTORMS...THE MOST INTENSE MAY PRODUCE:
    HAIL UP TO THE SIZE OF GOLF BALLS.
    DAMAGING WINDS IN EXCESS OF 60 MPH.
    VERY HEAVY RAIN.

  DISCUSSION:

  SCATTERED THUNDERSTORMS WILL AFFECT PORTIONS OF FAR NORTHERN

  A STRONG WARM FRONT WILL STALL OUT OVER THE REGION THIS
  AFTERNOON WITH VERY WARM AND HUMID AIR ALONG AND SOUTH OF THE
  FRONT. A WEAK UPPER LEVEL DISTURBANCE WILL TRACK INTO THE REGION
  LATE THIS AFTERNOON AND EVENING...LEADING TO THE POTENTIAL FOR

  EXIST FOR ANY STORMS THAT DO FORM TO BECOME SEVERE WITH THE
  POTENTIAL FOR LARGE HAIL AND DAMAGING WINDS.

  FINALLY...A LARGE AREA OF SHOWERS AND THUNDERSTORMS THAT FORM
  OVER THE PLAINS THIS AFTERNOON COULD MOVE INTO MAINLY WESTERN
  PORTIONS OF THE OUTLOOK AREA LATE TONIGHT. THE PRIMARY THREAT
  FROM THUNDERSTORMS LATE TONIGHT WOULD BE HEAVY RAIN.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.

SOME PERIODS OF THUNDERSTORMS ARE LIKELY WEDNESDAY INTO WEDNESDAY
NIGHT. THE POTENTIAL DOES EXISTS FOR SOME OF THE THUNDERSTORMS TO
BECOME SEVERE...ESPECIALLY SOUTH OF INTERSTATE 80 WEDNESDAY

AREA RIVERS AND STREAMS.
