AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1235 AM CDT THU JUN 19 2014

.DISCUSSION...
301 PM CDT

SYNOPSIS...THE UNSTABLE PATTERN CONTINUES WITH MULTIPLE PERIODS OF
THUNDERSTORMS POSSIBLE.  TEMPERATURES WILL BE CLOSELY TIED TO
THUNDERSTORM DEVELOPMENT AS WE SAW TODAY.  HAVE 80S TO 90S FOR THE
REST OF THIS WEEK THEN FINALLY COOLING INTO THE LOWER 80S NEXT WEEK.

REST OF TODAY THROUGH FRIDAY NIGHT...
OVERALL CONFIDENCE IS LOW IN THE FORECAST. NONE OF THE GUIDANCE
MEMBERS HANDLED THIS MORNING/S CONVECTION WELL SO THE MODELS RUNS
ARE SUSPECT. DID NOT WANT TO MAKE MAJOR CHANGES TO THE FORECAST SO
BACKED OFF ON POPS AND TEMPS IN REASONABLE PLACES.

AN UPPER LEVEL SHORTWAVE IS MOVING OVER SOUTHERN WI WITH RIDGING
SETTING UP RIGHT BEHIND IT.  THE RIDGE WILL SIT OVER THE REGION
THROUGH THURSDAY NIGHT.  AT THE SURFACE A LOW IS OVER NEBRASKA AND A
BOUNDARY STRETCHES FROM MUSCATINE IOWA TO LINCOLN ILLINOIS TO
LAFAYETTE INDIANA.  CLOUD COVER REMAINS THICK OVER THE REGION AND
TEMPERATURES ARE STRUGGLING TO WARM. WE ARE ALSO VERY STABLE SO
EXPECTING ANY FURTHER SHOWER OR THUNDERSTORM DEVELOPMENT TO OCCUR
OVER WI AND/OR IA WHERE THEY HAVE HAD BETTER RECOVERY FROM THIS
MORNINGS CONVECTION.  A STRAY SHOWER MAY SINK SOUTH INTO FAR
NORTHERN IL BUT IN GENERAL THINKING THE REST OF THIS AFTERNOON
SHOULD BE RELATIVELY QUIET.

MAY SEE SOME STORMS TONIGHT WITH THE BOUNDARY AND SHORTWAVE IN THE
REGION. HOWEVER BACKED OFF ON POPS DUE TO HOW STABLE WE ARE RIGHT
NOW.  I AM PROBABLY STILL TOO HIGH WITH POPS TONIGHT BUT DECIDED TO
BACK OFF SLOWLY.  ALSO LOWERED LOWS BY A FEW DEGREES SINCE MOST
PLACES NORTH OF I-80 WILL LIKELY NOT GET OUT OF THE LOWER 80S THIS
AFTERNOON.

THE RIDGE MOVES OVERHEAD TOMORROW BUT THE PLAIN/S LOW STATIONARY
FRONT REMAINS OVER THE REGION. IT WILL BE ANOTHER DIFFICULT DAY AS
FAR AS WHERE AND WHEN THUNDERSTORMS WILL FORM.  SOME GUIDANCE
MEMBERS SUGGEST WE WILL HAVE LINGERING NOCTURNAL CONVECTION AGAIN
WHICH WOULD SUPPRESS ADDITIONAL STORMS.  OTHERS SUGGEST WE WILL HAVE
THUNDERSTORMS ALL DAY ALONG THE BOUNDARY. AS SUCH HAVE CHANCE POPS.
TEMPS WILL ONCE AGAIN BE A CONCERN ESPECIALLY IF CLOUD COVER LINGERS
THROUGH THE DAY. BACKED OFF ON HIGH TEMPS A BIT DUE TO CLOUD COVER
BUT STILL HAVE HIGHS IN THE UPPER 80S TO LOWER 90S AWAY FROM THE
LAKE.  FLOW WILL BE OFF OF THE LAKE SO TEMPS WILL BE LIMITED TO THE
70S.  SHEAR AND CAPE ARE NOT AS PLENTIFUL TOMORROW SO THINKING WHILE
WE MAY HAVE A FEW STRONG TO BORDER LINE SEVERE STORMS...WIDESPREAD
SEVERE WEATHER IS NOT EXPECTED.

GUIDANCE SUGGESTS STORMS WILL FIRE ALONG A VORTICITY STREAMER
THURSDAY NIGHT AND PUSH INTO OUR REGION EARLY IN THE MORNING. THE
RIDGE AXIS ALSO SHIFTS TO OUR EAST FRIDAY WITH NORTHWEST FLOW
SETTING UP. THINKING FRIDAY WILL BE SIMILAR TO TODAY WHERE NOCTURNAL
CONVECTION IS THE MAIN SHOW.  AS SUCH BACKED OFF ON FRIDAY/S HIGH
TEMPS TOO BUT KEPT THEM IN THE MID 80S AWAY FROM THE LAKE AS THE
GROUND SHOULD WARM UP QUICKLY IN THE AFTERNOON.  TEMPS ALONG THE
LAKE WILL BE AROUND 80 DUE TO ONSHORE FLOW.  FRIDAY LOOKS QUIET WITH
CLEARING SKIES AND LOWS IN THE 60S.

SATURDAY AND SUNDAY...
MULTIPLE UPPER LEVEL SHORTWAVES WILL PASS OVER THE REGION THIS
WEEKEND. HIGH PRESSURE WILL BE OVER THE EASTERN GREAT LAKES AND IF
THE HIGH DRIFTS FARTHER WEST...IT COULD HELP LIMIT THUNDERSTORM
DEVELOPMENT. HAVE LOW CONFIDENCE IN THUNDERSTORMS SATURDAY...AND
HAVE POPS INCREASING THROUGH THE DAY TO CHANCE IN THE AFTERNOON AND
OVERNIGHT AHEAD OF THE FIRST SHORTWAVE.  SUNDAY LOOKS TO HAVE THE
BETTER CHANCE OF THUNDER WITH THE SHORTWAVES AND GREATER
INSTABILITY. SHEAR LOOKS LOW ON BOTH DAYS SO MAY SEE SOME STORMS
PULSE UP ON SUNDAY BUT NOT EXPECTING WIDESPREAD SEVERE WEATHER.  FOR
TEMPS HAVE HIGHS IN MID TO UPPER 80S BOTH DAYS. SOUTHEAST FLOW ON
SATURDAY COULD LEAD TO COOLING IN LAKE COUNTY IL...WHILE NO LAKE
COOLING IS EXPECTED SUNDAY.

MONDAY AND NEXT TUESDAY...
THE PARADE OF SHORTWAVES CONTINUES INTO EARLY NEXT WEEK WITH A WEAK
SURFACE LOW MOVING INTO THE MID MISSISSIPPI VALLEY TUESDAY OR
WEDNESDAY.  HAVE CONTINUED PERIODIC CHANCES OF STORMS BUT LOOKING AT
COOLER TEMPS BEHIND THE RIDGE.  HIGHS WILL STILL BE IN THE 80S BUT
IN THE LOW TO MID 80S.  ONSHORE FLOW IS ALSO EXPECTED WITH LAKE SIDE
COOLING.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 06Z...

* TSRA THROUGH SUNRISE.
* CHANCE OF TSRA LATE MORNING/EARLY AFTERNOON.
* TSRA LATE THURSDAY NIGHT INTO FRIDAY MORNING.
* IFR CIGS THROUGH SUNRISE/MVFR CIGS THURSDAY MORNING.
* NORTHEAST/EAST WINDS THROUGH THE PERIOD. CMS

//DISCUSSION...UPDATED 06Z...

NO SIGNS OF TSRA ENDING OR DISSIPATING AND WILL CONTINUE WITH THE
MOST RECENT AMENDMENTS OF TSRA MENTION NOW THROUGH 11Z. WITH THE
BULK OF THIS ACTIIVTY BEING DRIVEN BY WARM AIR ADVECTION...EXPECT
TO SEE SOME WEAKENING AROUND/AFTER SUNRISE BUT NOT CONFIDENT IN
EXACT END TIME AND ACTIVITY COULD PERSIST BEYOND SUNRISE. THERE
ARE TRENDS SUGGESTING ACTIVITY WILL END OR BE SHIFTING WEST BY
MID MORNING WITH THE POSSIBILITY OF ADDITIONAL ACTIVITY DEVELOPING
WITH DAYTIME HEATING IN THE LATE MORNING OR EARLY AFTERNOON. IF
THIS OCCURS...IT SHOULD BE SHORT LIVED AS FOCUS FOR CONVECTION
SHIFTS WEST THROUGH THE DAY LEAVING MAINLY DRY CONDITIONS INTO
THE EVENING HOURS. MORE DISCERNABLE UPPER LEVEL WAVE PROGGED TO
MOVE ACROSS THE REGION LATER THURSDAY NIGHT INTO FRIDAY MORNING
WITH ADDITIONAL TSRA POSSIBLE DURING THIS TIME AND DESPITE CURRENT
DISTANCE...24-30 HRS...ADDED PROB MENTION TO ORD/S TAF.

IFR CIGS HAVE BEEN IN AND OUT AT ORD/MDW AND WITH THE COOLER
NORTHEAST FLOW...MOIST LOW LEVELS AND CONTINUED TSRA ACTIVITY...
POTENTIAL FOR IFR CIGS WILL CONTINUE BUT JUST NOT SURE HOW
WIDESPREAD OR HOW LONG THEY WILL PERSIST. BUT HAVE BEEN CARRYING
THEM ALL EVENING AND WILL CONTINUE WITH IFR CIGS OVERNIGHT WITH
CIGS LIFTING TO MVFR EITHER BY SUNRISE OR SHORTLY THEREAFTER.

DESPITE EASTERLY WINDS...IF WINDS DIMINISH ENOUGH OVERNIGHT INTO
MID THURSDAY MORNING...THERE COULD BE A LAKE BREEZE LATER THIS
AFTERNOON...WITH A SHIFT MORE TO THE NORTHEAST. SPEEDS WILL THEN
DIMINISH SOME THIS EVENING. CMS

//ORD AND MDW CONFIDENCE...UPDATED 06Z...

* HIGH FOR TSRA THROUGH SUNRISE.
* LOW FOR TSRA DURING DAYLIGHT HOURS TODAY.
* MEDIUM FOR TSRA THURSDAY NIGHT/FRIDAY MORNING.
* MEDIUM FOR IFR CIGS THROUGH SUNRISE...MEDIUM FOR MVFR CIGS
  THURSDAY MORNING.

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

* FRIDAY THROUGH TUESDAY...CHANCE OF TSRA.

&&

.MARINE...
146 PM CDT

WIND DIRECTION WILL CONTINUE TO BE THE GREATEST CHALLENGE FOR THE
NEXT 24 HOURS...IN ADDITION TO THE POTENTIAL FOR ANOTHER ROUND OF
THUNDERSTORMS. A BROAD RIDGE OF HIGH PRESSURE CENTERED OVER HUDSON
BAY WILL BEGIN TO STRETCH SOUTH OVER SOUTHERN LOWER MICHIGAN. TO
THE WEST A NEARLY STATIONARY FRONTAL BOUNDARY THAT HAS BEEN THE
FOCAL POINT FOR THUNDERSTORMS WILL BECOME ORIENTED FROM THE
SOUTHERN TIP OF THE LAKE STRETCHING NORTHWEST THROUGH SOUTHWEST
MINNESOTA THIS EVENING. IN GENERAL...SOUTH WINDS ARE EXPECTED
SOUTH OF THE BOUNDARY WITH NORTHEAST WINDS NORTH OF THE BOUNDARY.
AN AREA OF LOW PRESSURE OVER THE PLAINS WILL EVENTUALLY LIFT NORTH
AND ALLOW THE FRONTAL BOUNDARY TO LIFT BACK NORTH OVER THE LAKE
THURSDAY NIGHT INTO FRIDAY. HIGH PRESSURE WILL BUILD JUST EAST OF
LAKE MICHIGAN LATE IN THE WEEK INTO THE WEEKEND AND SHOULD RESULT
IN RELATIVELY MODEST WINDS ACROSS THE LAKE THIS WEEKEND INTO EARLY
NEXT WEEK.
