AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
906 AM CDT WED JUL 10 2013

.DISCUSSION...
305 AM CDT

FORECAST CHALLENGES THIS WEDNESDAY MORNING INCLUDE STILL AWAITING
THE ARRIVAL OF CONVECTION. JOKING ASIDE...IT IS IMPRESSIVE TO GET
THROUGH THIS VERY HIGH PWAT AND UNSTABLE AIR ALOFT /MUCAPES
2000-3500 J/KG/ WITHOUT CONVECTION FROM MIDDAY YESTERDAY THROUGH
LAST NIGHT. IT REMINDED HOW IMPORTANT THE TIMING OF A TRIGGER OR
SOME FORM OF FOCI ARE FOR CONVECTION...OR INHIBITING DEVELOPMENT IF
IN THE WAKE OF SUCH FEATURES. BUT BACK TO THE CHALLENGES GOING
FORWARD...THERE IS A CHANCE FOR CONVECTION THIS MORNING SOUTH OF
I-80 AS THE SURFACE TROUGH /A FOCUS!/ TAPS THE LAST OF THE MOIST AND
UNSTABLE AIR. THEN ATTENTION TURNS TO HOW QUICKLY TEMPERATURES WILL
WARM AFTER THE SEASONAL AIR ON THU AND FRI.

THIS MORNING...WELL-DEFINED UPPER TROUGH ACROSS WESTERN ONTARIO TO
NORTHERN IA IS PROGRESSING ESE. THE SURFACE TROUGH EXTENDS FROM A
1000MB LOW IN EASTERN ONTARIO TO THE QUAD CITIES AT 3 AM THIS
MORNING. DEW POINTS IN THE MID 70S ARE POOLED ACROSS THE AREA
OFFERING A MUGGY START TO THE DAY. SCATTERED ACCAS IS SEEN ON IR IN
THE REGION BUT NO SIGNS ON RADAR OR SATELLITE OF THIS DEVELOPING. A
SHORT WAVE IMPULSE SEEN ON WATER VAPOR AND 700MB PROFILER ANALYSIS
IS TRAVERSING SOUTHERN IA/NORTHERN MO...BASICALLY ALONG THE BASE
OF THE PRIMARY TROUGH. WHILE CONVECTIVE ALLOWING GUIDANCE SUCH AS
THE HRRR DOES HAVE CONVECTIVE DEVELOPMENT TRAVERSING THE FAR
SOUTHERN FORECAST AREA WITH THIS AND ALONG THE SURFACE BOUNDARY
DURING MID-MORNING...RADAR TRENDS SHOW SUBTLE ECHOES FURTHER SOUTH.
THE LOW-LEVEL JET HAS VEERED AND THE MORE SUBSTANTIAL MOISTURE
TRANSPORT HAS ALSO ENDED EARLY THIS MORNING...SO NOT SEEING TOO MUCH
HAPPENING. SO ONLY MAINTAINED LOW T-STORM CHANCES IN THE SOUTHERN
FORECAST AREA.

THIS AFTERNOON INTO TONIGHT...SUBSTANTIAL COLUMN DRYING IS FORECAST
AS THE AFTERNOON PROGRESSES. SURFACE DEW POINTS WILL FALL SLOWLY
THROUGH THE 60S AND WILL LIKELY STILL SUPPORT AT LEAST FEW AND
POTENTIALLY SCATTERED CU. THE 850MB TEMPERATURES IN THE MID-UPPER
TEENS FORECAST AT 18Z ACROSS THE FORECAST AREA...ALONG WITH THE WARM
STARTING POINT FOR TEMPERATURES...INDICATE MANY COMMUNITIES
REACHING THE MID AND POTENTIALLY UPPER 80S. AREAS NEAR THE WI STATE
LINE ARE MORE LIKELY TO FLAT-LINE IN TEMPERATURES THIS AFTERNOON AS
THE COOL FRONT PORTION OF THIS TROUGH WORKS THROUGH. NORTHWEST WINDS
IN THE BOUNDARY LAYER WILL BE RIGHT AT THE CUSP AT KEEPING A LAKE
BREEZE AT BAY FOR CHICAGO BUT SOME COOLING OF SEVERAL DEGREES COULD
BE SEEN BY MID-AFTERNOON IMMEDIATELY NEAR THE IL LAKESHORE AND
DEFINITELY NEAR THE IN SHORE.

THURSDAY THROUGH FRIDAY...A QUIET TIME AS SURFACE HIGH PRESSURE ON
THE ORDER OF 1019 MB MOVES ATOP THE AREA. THERE SHOULD BE LIMITED
CIRRUS AND ONLY FEW CU DURING THE AFTERNOONS. A MODEL BLEND
TYPICALLY DOES VERY WELL FOR TEMPS IN THIS TYPE OF CALM REGIME AND
HAVE BLENDED THAT WITH GOING FORECAST.  TEMPERATURES SHOULD BE
WITHIN A COUPLE DEGREES OF OR RIGHT AT NORMAL.

THIS WEEKEND INTO EARLY NEXT WEEK...THE TREND IN LONG RANGE GUIDANCE
CONTINUES TO POINT TOWARD A WARMER AND DRIER TIME THAN SOLUTIONS
FROM A COUPLE DAYS AGO WITH STOUT UPPER RIDGING FROM THE WEST
SOUTHWEST STRETCHING OVER THE AREA. THE ADVANCING RIDGE FROM THE
WEST LATE THIS WEEK GETS HELD UP WITH BOTH A CLOSED LOW IN THE
NORTHEAST/MID-ATLANTIC AND TROPICAL STORM CHANTAL...FORECAST BY NHC
TO BE NEAR THE GA/SC SHORE BY LATE SUNDAY. 500MB HEIGHTS IN EXCESS
OF 594DM ARE FORECAST BY BOTH THE EC AN GFS FOR THE WEEKEND. WHILE
THE EC WEAKENS THIS MORE THAN THE GFS EARLY NEXT WEEK...THE PATTERN
FORECAST IS STILL BLOCKED AND RIDGE RIDING ACTIVITY IS FORECAST FOR
MOST OF THIS TIME FAIRLY FAR NORTH. BUT AS WE SAW IN THE JUNE 22-26
STRETCH...THAT CAN EVOLVE FURTHER SOUTH THAN LONG RANGE SOLUTIONS
SHOW AS MULTIPLE ROUNDS OF CONVECTION FIRE. BUT THIS IS CERTAINLY A
STRONGER RIDGE FORECAST THIS FAR NORTHEAST. THE 850MB 20C TEMP
CONTOUR FLIRTS WITH THE CWA ON BOTH SOLUTIONS FROM SAT THROUGH TUE.
HAVE BOOSTED TEMPS A COUPLE DEGREES FURTHER AND IF THAT THERMAL
RIDGE ENDS UP FURTHER SOUTH UNCONTAMINATED WITH CONVECTIVE
CLOUDS...CAN CERTAINLY ENVISION AT LEAST LOW 90S AWAY FROM THE LAKE
FOR MULTIPLE DAYS. BUT CONFIDENCE ENVELOPE...WHILE NOT OVERLY
LARGE...IS CENTERED MORE ON UPPER 80S /LOW-MID NEAR THE LAKE/. THE
EASTERN ATLANTIC/GULF FLOW LOOKS TO RETURN HIGHER DEW POINTS BY SUN
OR MON.

.AVIATION...

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

* NORTHWEST WINDS INCREASING THROUGH MID MORNING WITH GUSTS IN THE
  UPPER TEENS...BEFORE WINDS SHIFT TO THE NORTHEAST IN THE
  AFTERNOON WITH LAKE INFLUENCE.

MDB

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

AS THE FRONTAL BOUNDARY IS CURRENTLY SOUTH OF THE TERMINALS THIS
MORNING...THE SHOWER/TS DEVELOPMENT ACROSS CENTRAL ILLINOIS WILL
REMAIN SOUTH OF THE TERMINALS TODAY. ALTHOUGH WITH FROPA AND A
WEAK GRADIENT IN PLACE...SOME SCATTERED LOWER CEILINGS AND FOG
REMAIN NEAR THE TERMINALS. WITH THE SUN QUICKLY RISING THIS
MORNING...ANY LINGERING FOG/CEILINGS SHOULD QUICKLY DIMINISH WITH
LATEST SATELLITE IMAGERY ALREADY SHOWING THIS OCCURRING. ALTHOUGH
IT WOULD NOT BE OUT OF THE QUESTION FOR A BRIEF PERIOD OF LOWER
CEILINGS AROUND 2KFT OVER THE NEXT HOUR...MAINLY FOR MDW/GYY. ANY
FURTHER CLOUD DEVELOPMENT TODAY SHOULD REMAIN SCATTERED AS DRIER
AIR CONTINUES TO PUSH SOUTH ON INCREASING NORTHWEST WINDS THIS
MORNING. RFD AND DPA SHOULD REMAIN NORTHWEST WITH GUSTS INCREASING
BY MID MORNING...WITH ORD/MDW/GYY LIKEWISE OBSERVING THIS TREND
BUT ONLY THROUGH THE MORNING. EXPECT A TREND TOWARDS A NORTHEAST
DIRECTION BY EARLY AFTERNOON FOR ORD/MDW/GYY...REMAINING THIS
DIRECTION UNTIL LATER THIS EVENING.

RODRIGUEZ

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

* HIGH CONFIDENCE IN WIND FORECAST THROUGH EARLY
  AFTERNOON...MEDIUM CONFIDENCE THAT A SHIFT TO NORTHEAST WILL
  OCCUR THIS AFTERNOON...MEDIUM CONFIDENCE IN TIMING OF SHIFT.

.MARINE...
416 AM CDT

AS A TROUGH OF LOW PRESSURE AND ASSOCIATED COLD FRONT BEGIN TO
PUSH EAST ACROSS THE NORTHERN PORTIONS OF THE LAKE THIS
MORNING...A FAIRLY TIGHT PRESSURE GRADIENT HAS HELPED SOUTHWEST
WINDS TO INCREASE TO 15 TO 25 KT OVER THE NORTHERN PORTIONS OF THE
LAKE WHILE AREAS FURTHER SOUTH ARE OBSERVING SPEEDS OF 10 TO 20
KT. AS THIS TROUGH/FRONT CONTINUE SOUTHEAST DOWN THE LAKE THIS
MORNING...EXPECT THESE SOUTHWEST WINDS TO SHIFT TO THE
WEST/NORTHWEST AND THEN HOLD ONTO A NORTHWEST DIRECTION FOR THE
REMAINDER OF THE DAY INTO TONIGHT. EXPECT LIGHT NORTHERLY FLOW
OVER THE LAKE FOR MOST OF THURSDAY AS HIGH PRESSURE SLOWLY SHIFTS
EAST TOWARDS THE CENTRAL GREAT LAKES. BY FRIDAY WINDS TURN BACK TO
A SOUTHERLY DIRECTION...AS THIS HIGH SETTLES OVER THE EASTERN
GREAT LAKES INTO THE WEEKEND.
