AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
245 PM CDT TUE MAY 21 2013

.DISCUSSION...
1228 PM CDT

MORNING HWO UPDATE WAS SENT AFTER THE 1630Z SPC DAY ONE OUTLOOK WAS
RECEIVED...IN ANTICIPATION THAT THE LOCAL AREA WOULD BE PULLED
FROM THE SLIGHT RISK. THIS IS IN FACT WHAT OCCURRED...AS MODELS
ARE SHOWING LESS POTENTIAL FOR THE AREAS OF GREATEST INSTABILITY
TO BE ALIGNED WITH DEEP LAYER SHEAR THAT WOULD BE SUPPORTIVE OF
ORGANIZED CONVECTION.

LATEST VIS SATELLITE IMAGERY IS STILL SHOWING QUITE A WIDE AREA
WITH LITTLE CU DEVELOPMENT ACROSS IL AS YOU GET FARTHER AWAY FROM
THE UPPER LOW POSITIONED OVER THE EASTERN DAKOTAS. MODEL FCST
SOUNDINGS ARE SIMILAR TO LATEST ACARS PROFILES IN SHOWING A WEAK
CAP STILL IN PLACE BETWEEN 850-800 MB OR SO...AND THEN ANOTHER
WARM LAYER ABOVE 500 MB THAT MIGHT LIMIT VERTICAL DEVELOPMENT.
LATEST IR/WV IMAGE SUGGESTS THE PRESENCE OF A WEAK SHORTWAVE
LIFTING ACROSS EASTERN IOWA BUT ALSO POINTS TO THE BEST MOISTURE
CONVERGENCE BEING FOCUSED ACROSS THE SOUTHERN MIDWEST WHERE
THUNDERSTORM CLUSTERS HAVE ALREADY DEVELOPED. BY TONIGHT...DIURNAL
HEATING WILL BE LESS FAVORABLE BUT BETTER SHORTWAVE ENERGY...SFC
AND MIDLEVEL MOISTURE...AND COOLER TEMPERATURES ALOFT WILL SUPPORT
AN INCREASED CHANCE OF TSRA AHEAD OF AN APPROACHING COLD FRONT.

LENNING

//PREV DISCUSSION...
321 AM CDT

TODAY THROUGH TONIGHT...
MAIN CONCERN FOR TODAY REVOLVES AROUND THE POTENTIAL FOR SEVERE
WEATHER...MAINLY ALONG AND EAST OF A PONTIAC TO CHICAGO LINE.

LINE OF SHOWERS AND THUNDERSTORMS FROM EARLY THIS MORNING CONTINUES
TO PUSH EAST...STRETCHING FROM LOWER MICHIGAN SOUTH THROUGH SOUTHERN
IN. THIS AREA OF CONVECTION HAD BROUGHT SEVERE WEATHER TO PORTIONS
OF NORTHERN IL LAST EVENING...ASSOCIATED WITH A TONGUE OF
ANOMALOUSLY HIGH MOISTURE. PWAT VALUES WITHIN THIS CHANNEL OF
MOISTURE HOVERED BETWEEN 1.2-1.6" AS SOME DRYING WAS NOTED ACROSS
NORTHERN MISSOURI/SOUTHERN IOWA IN THE WAKE OF THE EVENINGS
CONVECTION. TEMPS SHOULD HOLD UP EARLY THIS MORNING IN THE MID/UPR
60S. THEN THE FOCUS TURNS TOWARDS TIMING OF CONVECTION AND THE
INTENSIFY...POSSIBLY SEVERE WEATHER AGAIN.

GUIDANCE INDICATES ANOTHER CAP WILL DEVELOP AND HOLD THRU MOST OF
THE MORNING TIMEFRAME...THEN THE QUESTION IS WHEN THIS CAP WILL
DISSOLVE. LCL GUIDANCE SUGGESTS THE MORE FAVORED ZONE FOR THE
STRONGEST INSTABILITY WILL BE ALONG AND EAST OF A PONTIAC TO GARY
LINE...WHERE LAPSE RATES WILL STEEPEN QUICKLY BY MIDDAY/AFTERNOON.
THE OVERALL SYSTEM THAT HAS PRODUCED THE WIDESPREAD SEVERE WEATHER
REMAINS NEGATIVELY TILTED...WHICH THIS TYPE OF A SETUP COUPLED WITH
INSTABILITY AND ABNORMALLY HIGH MOISTURE...HAS A TENDENCY TO LEAD TO
SEVERE WEATHER OCCURRENCE. THE CHALLENGE IS TRYING TO PIN DOWN THE
TIMING/PLACEMENT...AND ONCE AGAIN THE LACK OF A TRIGGER. A WEAK LOBE
OF VORTICITY DOES APPEAR TO BE PROGGED TO SLIDE NORTH THROUGH
SOUTHCENTRAL IL DURING THE AFTN HOURS...WHICH MAY AID IN INITIATION
OF CONVECTION ACROSS THE SOUTHEASTERN CWFA DURING THE AFTN/EVE
HOURS. PROGGED WIND FIELDS ARE MORE UNIFORM...WHICH SHOULD LIMIT THE
HAZARDS TO A WIND/HAIL THREAT. EXPECT ANY CONVECTION TO FORM INTO A
LINE SEGMENTS SHORTLY AFTER GENERATION.

TEMPS WILL BE DIFFICULT TO PINDOWN FOR THIS AFTN AS WELL. GIVEN THE
RECENT RAINFALL...COUPLED WITH SLIGHTLY COOLER AIR ALOFT TO KEEP
TEMPS CLOSER TO THE LOW 80S FOR MUCH OF THE CWFA. THE FAR SOUTHEAST
CWFA MAY TOUCH THE MID 80S.

THE CHANNEL OF MOISTURE WILL CONTINUE TO HOVER ACROSS THE CWFA
THROUGH THE OVERNIGHT HOURS...AS DEW POINTS REMAIN IN THE LOW/MID
60S. HAVE MAINTAINED LIKELY POPS THRU THE OVERNIGHT HOURS...WITH A
CONTINUED THUNDERSTORMS MENTIONED. FEEL THAT AS TIME MOVES FORWARD
THIS WILL BE ABLE TO BE FINE TUNED...AND POSSIBLY LIMIT CONVECTION
TO
THE EASTERN CWFA.

CONFIDENCE IN SEVERE WEATHER INITIATION...LOW/MEDIUM.

WEDNESDAY THROUGH THURSDAY...
500MB TROUGH AXIS FINALLY ARRIVES ACROSS OVERHEAD...HOWEVER REMAINS
IN A NEGATIVELY TILTED STATE. IT APPEARS INSTABILITY WILL BE WAINING
A BIT THROUGHOUT THE DAY...SO HAVE TRIMMED BACK TO A SLIGHT CHC OF
THUNDER. THIS SEEMS REASONABLE GIVEN THE ABUNDANCE OF CLOUDS. TEMPS
WILL BE MUCH COOLER WED...MAINLY IN THE MID 70S. FOR THUR THE 500MB
VORT SLOWS ACROSS THE CWFA...WITH COOLER AIR SLOWLY FILTERING INTO
THE NEAR SFC ENVIRONMENT. WINDS WILL SLOWLY TURN NORTHERLY BEHIND A
FRONTAL BOUNDARY...THEN NORTHEASTERLY EARLY THUR. THIS WILL ALLOW
THE MARINE ENVIRONMENT TO FILTER INTO FAR NORTHEAST IL...KEEPING
TEMPS IN THE UPR 50S THUR. ANTI-CYCLONIC FLOW IS PROGGED TO ARRIVE
ACROSS THE REGION THUR AFTN/EVE...BRINGING AN END TO THE PRECIP.

CONFIDENCE...MEDIUM/HIGH.

FRIDAY THROUGH MONDAY...
ENSEMBLES HAVE CONTINUED TO SUGGEST THE DEPARTING 500MB TROUGH WILL
BUMP UP AGAINST A WESTERN ATLANTIC RIDGE. THIS WILL SLOW THE
EASTWARD PROGRESSION OF THE TROUGH...WHICH SHUD HOLD THE
ANTI-CYCLONIC FLOW ACROSS THE GREAT LAKES REGION THRU FRI NGT WITH
DRY WEATHER. CONSIDERABLE DIFFERENCES ON PRECIP RETURNING TO THE
REGION AMONGST GUIDANCE FOR SAT/SAT NGT...WHICH IS MOST LIKELY A
REFLECTION OF THE SLOWING TREND AND THE MID-LVL RIDGE THAT IS
PROGGED TO BUILD ACROSS THE CENTRAL CONUS INTO THE CANADIAN PRAIRIES
SAT/SUN. MUCH COOLER AIR WILL REMAIN IN PLACE FOR THE START OF THE
EXTENDED...AS TEMPS STRUGGLE TO REACH THE MID/UPR 60S...AND FOR
AREAS ADJACENT TO LAKE MICHIGAN...TEMPS MAY ACTUALLY STRUGGLE TO
REACH THE UPR 50S AS THE COOLER MARINE ENVIRONMENT FLOWS INLAND FROM
A NORTHEAST WIND. THEN TEMPS WILL BEGIN TO WARM FOR THE WEEKEND INTO
THE UPR 60S TO NEAR 70 DEG. THEN BY EARLY NEXT WEEK TEMPS SHOULD
STEADILY WARM INTO THE LOW 70S. HAVE HELD ONTO MENTION OF SLIGHT CHC
POPS IN THE LATER PERIODS OF THE EXTENDED...HOWEVER IT IS POSSIBLE
THAT AS HEIGHTS INCREASE ALOFT THAT DIFFLUENT FLOW WILL INHIBIT THE
PRECIP POTENTIAL. COULD SEE THINGS TRENDING DRIER FOR THE FINAL FEW
PERIODS OF THE EXTENDED.

IN THE WAKE OF LAST NIGHTS SHOWERS AND STORMS...THINGS HAVE
STABILIZED FOR NOW. EXPECT MOSTLY CLEAR SKIES THROUGH THE MORNING
HOURS. BY MID DAY EXPECT ATMOSPHERE TO BEGIN TO DESTABILIZE AGAIN
BUT DONT SEE ANY REAL FOCUS FOR THUNDERSTORMS TO DEVELOP.
SCATTERED THUNDERSTORMS ARE POSSIBLE IN THE AFTERNOON AND EVENING
BUT DONT HAVE ENOUGH CONFIDENCE IN TIMING OR LOCATION TO PUT
THUNDER IN THE TAFS AT THIS TIME. WAVE ROUNDING THE BASE OF THE
PLAINS TROF OVER EASTERN NM THIS MORNING WILL LIFT NORTHEAST
TOWARD ILLINOIS LATE TONIGHT. THIS SHOULD BE THE FOCUS FOR MORE
WIDESPREAD SHOWERS AND THUNDERSTORMS LATE TONIGHT INTO WEDNESDAY
MORNING.

SOUTH WINDS WILL BE INCREASING THIS MORNING AND TURNING SW THIS
AFTERNOON. WINDS WILL DIMINISH AND GUSTINESS WILL END THIS
EVENING. WINDS WILL BECOME LIGHT AND VARIABLE LATE TONIGHT AS WEAK

1155 AM CDT TUE MAY 21 2013 /1255 PM EDT TUE MAY 21 2013/

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

 WEATHER HAZARDS EXPECTED:

  THUNDERSTORMS...THE STRONGEST COULD PRODUCE:
    HAIL TO THE SIZE OF DIMES.
    WIND GUSTS TO 50 MPH.
    FREQUENT CLOUD TO GROUND LIGHTNING.
    HEAVY RAIN.

  AREAS AFFECTED AND TIMING:

  COMPARED TO EARLIER THINKING...THE SEVERE WEATHER THREAT HAS
  DECREASED ACROSS NORTHERN ILLINOIS AND NORTHWEST INDIANA.
  SHOWERS AND THUNDERSTORMS ARE STILL EXPECTED...ESPECIALLY THIS
  EVENING AND OVERNIGHT...AND A FEW COULD PRODUCE SMALL HAIL AND
  GUSTY WINDS ALONG WITH LOCALLY HEAVY RAIN...PRIMARILY IN
  NORTHWEST INDIANA.

  DISCUSSION:

  THE BEST CHANCE FOR SHOWERS AND THUNDERSTORMS APPEARS TO BE THIS
  EVENING INTO TONIGHT AHEAD OF AN APPROACHING COLD FRONT. THIS IS
  NOT AN OPTIMAL TIME FOR SURFACE BASED INSTABILITY...AND DEEP
  LAYER SHEAR ALSO DOES NOT APPEAR FAVORABLE FOR ORGANIZED
  CONVECTION DURING THAT TIME PERIOD. HEAVY RAINFALL AND LOCALIZED
  FLOODING STILL ARE A POSSIBILITY.

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

SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE WEDNESDAY AND
AGAIN SATURDAY THROUGH MONDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NECESSARY THROUGH TONIGHT.
