Hail and Damaging Winds in Illinois, April 12 to 13, 2014

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
913 AM CDT SAT APR 12 2014

.DISCUSSION...
306 AM CDT

TODAY...
THIS MORNING...LOW PRESSURE IS CENTERED OVER SOUTH DAKOTA WHILE A
WARM FRONT STRETCHES EAST ACROSS CENTRAL IOWA TO NEAR ROCHELLE AND
EAST INTO CHICAGO. THE WARM FRONT WILL LIFT NORTH INTO WISCONSIN
BY LATE THIS MORNING. WEAK CONVECTION HAS DEVELOPED ACROSS
NORTHWESTERN IOWA EARLY THIS MORNING AND IS PROGGED TO MOVE ALONG
THE IL/WI STATE LINE THIS MORNING...THOUGH SHOULD DISSIPATE AS IT
OUTRUNS THE MEAGER INSTABILITY CURRENTLY IN PLACE TO OUR WEST. AS
THE WARM FRONT LIFTS NORTH OF THE AREA TODAY...MID 50 DEWPOINTS IN
PLACE ACROSS FAR DOWNSTATE ILLINOIS WILL ALSO OVERSPREAD THE
AREA...ACCOMPANIED BY TEMPERATURES EXPECTED TO PUSH INTO MID TO
UPPER 70S RESULTING IN MODERATE SURFACE BASED INSTABILITY DEVELOPING
THIS AFTERNOON. MLCAPE VALUES IN EXCESS OF 1000 J/KG ARE EXPECTED
ESPECIALLY IN THE WESTERN COUNTIES THIS AFTERNOON...THOUGH SHOULD
REMAIN CAPPED AS THE BEST FORCING WILL BE TO OUR NORTH. THE CAPPING
DOES ERODE AS YOU HEAD FURTHER NORTH...AND CANNOT RULE OUT OUTFLOWS
FROM WISCONSIN SINKING SOUTH AND KICKING OFF A FEW THUNDERSTORMS...
PARTICULARLY IN THE NORTHERN COUNTIES OF THE CWA. IF THIS WERE TO
OCCUR...40-50KT DEEP LAYER SHEAR ALONG WITH THE MODERATE INSTABILITY
WOULD BE MORE THAN SUFFICIENT TO SUPPORT A SEVERE THREAT.

THIS EVENING THROUGH SUNDAY TONIGHT...
LOW PRESSURE WILL BE CENTERED OVER THE OKLAHOMA/TEXAS PANHANDLE
REGION WITH AN ELONGATED TROUGH EXTENDING NORTHEAST INTO SOUTHERN
WISCONSIN THEN INTO THE EASTERN GREAT LAKES WHICH WILL SERVE THE
FOCUS FOR MOST OF THE OVERNIGHT CONVECTION. BROAD SOUTHERLY FLOW
AHEAD OF THE OF TROUGH WILL RESULT IN CONTINUED MOISTENING OF THE
COLUMN WITH PWATS RISING TO AROUND 1.2-1.3 INCHES OR SO OVERNIGHT.
IN ADDITION...AN AXIS OF AROUND 1000 J/KG MUCAPE NEAR THE TROUGH
AXIS WILL EXTEND INTO PORTIONS OF NORTH CENTRAL ILLINOIS. BROAD
WARM/MOIST ADVECTION INTO THE REGION AS WELL AS WELL AS MODERATE
DIVERGENCE ALOFT ASSOCIATED WITH RIGHT ENTRANCE REGION OF THE JET
SHOULD PROVIDE SUFFICIENT ASCENT FOR CONVECTION TO FIRE ALONG AND
AHEAD OF THE TROUGH AXIS DURING THE LATE EVENING AND EARLY OVERNIGHT
WHICH WILL THEN SLOWLY SAG SOUTH INTO THE CWA. MEANWHILE...A LOW
LEVEL JET WILL DEVELOP OVER OKLAHOMA WITH THE BEST CONVERGENCE
FOCUSED ACROSS PORTIONS OF NORTHERN MISSOURI/IOWA. EXPECT THIS AREA
TO BECOME THE MAIN SHOW WITH AN MCS DEVELOPING IN UNSTABLE AND
MODERATELY SHEARED ENVIRONMENT...POSSIBLY EVEN CUTTING OFF ACCESS TO
THE SOME OF THE ENERGY TRANSPORT INTO OUR AREA WHICH WOULD THEN
RESULT IN A LULL IN THE PRECIP OVER OUR AREA LATER IN THE OVERNIGHT
HOURS. ANY MCS DEVELOPING OVER NORTHERN MISSOURI WOULD EVENTUALLY
LIFT NORTHEAST TO OR NEAR THE CWA BUT WOULD LIKELY BE IN A DECAYING
PHASE AS IT REACHES THE LOCAL AREA SUNDAY MORNING.

WITH CONVECTIVE DEBRIS MOVING OVERHEAD IT WILL BE DIFFICULT TO
RECOVER SUNDAY AND EXPECT MAINLY SOME LINGERING SCATTERED SHOWERS
WITH A FEW THUNDERSTORMS POSSIBLE DURING THE EARLY PART OF THE DAY.
MEANWHILE...SOUTHERN STREAM JET ROUNDING THE BASE OF THE LONGWAVE
TROUGH WILL BEGIN TO LIFT TOWARDS THE AREA WITH MODERATE TO STRONG
DIVERGENCE ALOFT DEVELOPING AS COUPLED JET DEVELOPS DURING THE
AFTERNOON RESULTING IN SURFACE CYCLOGENESIS ALONG THE MID
MISSISSIPPI VALLEY. LOW LEVEL JET IS PROGGED TO REDEVELOP SUNDAY
EVENING ACROSS ILLINOIS AND WILL PUSH PWATS UP TO AROUND AN INCH AND
A HALF. INSTABILITY WILL REMAIN MEAGER BUT STRONG DYNAMIC FORCING
SHOULD OFFSET THIS WITH SHOWERS/EMBEDDED THUNDERSTORMS
RE-INTENSIFYING LATE AFTERNOON AND INTO THE EVENING. DEEP LAYER WINDS
PARALLEL TO THE BOUNDARY WILL RESULT IN TRAINING OF HEAVY
SHOWERS/THUNDERSTORMS AND DEEP MOIST SOUNDINGS INDICATE THAT
RAINFALL WILL BE EFFICIENT. GLOBAL MODELS CONTINUE TO PAINT A STRIPE
OF 3 TO IN EXCESS OF 4 INCHES SOMEWHERE IN THE REGION...MOST LIKELY
INCLUDING PORTIONS OF NORTH CENTRAL ILLINOIS. FLOODING REMAINS A
CONCERN AND A HYDROLOGIC OUTLOOK //ESF// WILL BE RE-ISSUED IN THE
MEANTIME...THOUGH A FLOOD WATCH MAY WELL BE NEEDED EVENTUALLY.

THERE WILL BE A BIG BUST POTENTIAL SUNDAY FOR TEMPERATURES DEPENDING
ON WHERE EXACTLY THE FRONTAL BOUNDARY IS AND HOW QUICKLY IT
PROGRESSES WHICH CAN BE IMPACTED BY CONVECTIVE OUTFLOW AS WELL AS
COOL AIR FROM THE LAKE. LIKELY THERE WILL BE A TIGHT TEMPERATURE
CONTRAST SOMEWHERE WITH 70S ON THE WARM SIDE OF THE BOUNDARY AND
40S/50S ON THE COOL SIDE. PRECIP AND CLOUD COVER ADD ADDITIONAL
UNCERTAINTY...AS WELL AS THE POTENTIAL FOR A LAKE BREEZE TO DEVELOP
WITHIN THE WEAKER SYNOPTIC WINDS NEAR THE TROUGH AXIS.

MONDAY THROUGH FRIDAY...
MAIN UPPER TROUGH AXIS WILL PUSH EAST ACROSS THE PLAINS MONDAY WITH
ANOTHER SURFACE WAVE LIFTING FROM THE LOWER MISSISSIPPI VALLEY INTO
THE OHIO VALLEY. H85 TEMPS FALL STEADILY THROUGH THE DAY
MONDAY...EVENTUALLY BOTTOMING OUT AROUND -12C MONDAY NIGHT. BY
MONDAY MORNING...TEMPS ALOFT WILL SUPPORT SNOW FALLING INTO THE
BOUNDARY LAYER...THOUGH DURING THE DAY AT LEAST WITH TEMPS
REBOUNDING INTO THE LOW 40S SHOULD BE ENOUGH TO MELT ANY PRECIP
BEFORE OR AS IT HITS THE SURFACE. BY MONDAY NIGHT THOUGH WITH LOWS
FALLING INTO THE MID TO UPPER 20S...ANY LINGERING PRECIP WILL BE
SNOW. WEATHER SHOULD BE FAIRLY QUIET TUESDAY AND WEDNESDAY UNDER THE
INFLUENCE OF HIGH PRESSURE WITH WARMER AIR STARTING TO SPREAD BACK
INTO THE AREA LATER ON WEDNESDAY. CHANCES FOR RAIN RETURN LATE IN
THE WEEK.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 14Z...

* CLUSTER OF TSRA OVER FAR NORTHWEST IL EXPECTED TO CONTINUE TO
  TRACK EAST ALONG THE WI/IL BORDER THROUGH LATE MORNING.
  EXPECTATION IS THAT THESE WILL REMAIN NORTH OF THE ORD/MDW
  TERMINALS PROPER...THOUGH ARRIVAL/DEPARTURE ROUTES MAY BE
  AFFECTED.

* SOUTH WINDS INCREASING ABOVE 10 KT THIS MORNING AND TO 15-20 KT
  BY LATE MORNING WITH GUSTS 25KT DURING THE AFTERNOON. WINDS
  THEN EASING OFF AROUND SUNSET.
* CHANCE OF THUNDERSTORMS LATER THIS EVENING.
* MORE WIDESPREAD RAIN DEVELOPING LATER SUNDAY MORNING WITH MVFR
  CONDITIONS DEVELOPING.

RATZER/ED F

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

A WEAK WARM FRONT LYING WEST TO EAST ACROSS EXTREME NORTHERN IL AT
11 UTC WILL MOVE ONLY VERY SLOWLY NORTH TODAY AS RAIN AND EMBEDDED
THUNDERSHOWERS MOVE EAST OUT OF IOWA ALONG AND NORTH OF THE FRONT
THIS MORNING. AS THIS AREA OF PRECIP MOVES FARTHER EAST INTO
DEEPER DRIER AIR AND AWAY FROM WHAT LITTLE INSTABILITY THERE IS
BACK TO THE WEST... EXPECT IT TO FALL APART.

WITH LOW PRESSURE OVER SOUTH DAKOTA MOVING INTO IOWA LATER IN
THE DAY... WINDS WILL INCREASE OUT OF THE SOUTH WITH GUSTS FROM
LATE MORNING THROUGH EARLY EVENING. WARM MOIST AIR WILL SURGE
NORTHWARD INTO THE AREA LATER TODAY VIA THESE BRISK SOUTH WINDS
AND HELP FUEL SHOWER AND THUNDERSTORMS ALONG AND NORTH OF THE WARM
FRONT ASSOCIATED WITH THE AFOREMENTIONED LOW PRESSURE SYSTEM...
BUT MOSTLY LIKELY STAYING NORTH AND WEST OF ORD/MDW THROUGH THE
DAYLIGHT HOURS.

BETTER FORCING FOR RAIN AND THUNDERSTORMS COMES TOGETHER ACROSS THE
AREA LATER THIS EVENING AND INTO THE OVERNIGHT.  EXPECT SHOWERS AND
THUNDERSTORMS TO SPREAD FURTHER SOUTH AND EAST POTENTIALLY IMPACTING
THE TERMINALS FOR A PERIOD SOMETIME FROM MID EVENING INTO THE
OVERNIGHT. EXACT TIMING DIFFICULT TO PIN DOWN THIS FAR OUT
STILL... BUT WINDOW OF BETTER INSTABILITY APPEARS TO IMPACT
ORD/MDW BETWEEN 04-08Z. MORE WIDESPREAD RAIN WILL DEVELOP AFTER
DAYBREAK SUNDAY... LOWERING CONDITIONS TO MVFR... AND POSSIBLY IFR
FOR A PERIOD LATER.

//ORD AND MDW CONFIDENCE...UPDATED 14Z...

* MEDIUM CONFIDNECE IN TSRA TRACKING NORTH OF TERMINAL THROUGH
  ALTE MORNING.

* HIGH CONFIDENCE IN SOUTH WINDS INCREASING IN SPEED BY LATE
  MORNING TODAY... GUSTING DURING THE AFTERNOON.
* LOW CONFIDENCE IN TIMING AND LOCATION OF THUNDERSTORMS THIS
  EVENING AND OVERNIGHT.

COMPLEX WEATHER PATTERN TO IMPACT LAKE MICHIGAN THE NEXT 3 DAYS...
AND THE BEST INFORMATION WILL BE OBTAINED VIA GRAPHICS ON THE GREAT
LAKES WEB PORTAL RATHER THAN THE LEGACY GLF TEXT WHERE THE RICHNESS
OF ALL THE INFORMATION CAN MORE READILY BE DECIPHERED.  WINDS WILL
INCREASE ACROSS THE LAKE TODAY IN ADVANCE OF LOW PRESSURE
APPROACHING THE AREA FROM THE CENTRAL PLAINS.  A WEAK FRONTAL
BOUNDARY LIFTING BACK NORTH AS A WARM FRONT THIS MORNING WILL
SEPARATE SOUTH WINDS TO THE SOUTH FROM SOUTHEAST TO EAST WINDS
CENTRAL AND NORTH.  AS THE PLAINS LOW REACHES LAKE MICHIGAN TONIGHT
IT WILL DRAPE A FRONTAL BOUNDARY ACROSS THE CENTRAL AND SOUTHERN
PART OF THE LAKE.  AS WE MOVE INTO SUNDAY... YET ANOTHER AREA OF LOW
PRESSURE WILL LIFT NORTHEAST ALONG THE BOUNDARY AND REACH SOUTHERN
LAKE MICHIGAN BY LATE SUNDAY NIGHT.

A PERIOD OF NORTHERLY GALES IS EXPECTED TO DEVELOP BEHIND THIS LOW
PRESSURE AREA AS IT MOVES AWAY FROM THE AREA LATER SUNDAY NIGHT AND
MONDAY.  GALE WIND THRESHOLDS MAY FIRST BE SURPASSED ACROSS THE
CENTRAL PART OF THE LAKE WHERE THE GRADIENT TIGHTENS MOST INITIALLY
AND WHERE THERMAL INSTABILITY IS MAXIMIZED.  GALE FORCE WINDS WILL
SPREAD SOUTH EARLY MONDAY... AND MAY BE ALSO EXPERIENCED ACROSS THE
NORTH THIRD OF THE LAKE LATER MONDAY AS THE LOW PULLS AWAY.

BROAD HIGH PRESSURE WILL MOVE OVER THE LAKE LATER TUESDAY INTO
WEDNESDAY... BUT THIS PERIOD OF CALMER CONDITIONS WILL NOT BE LONG
LASTING AS THE GRADIENT INCREASES AGAIN AHEAD OF INVERTED LOW
PRESSURE ON THURSDAY.
