AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
442 AM CDT TUE JUL 14 2015

.SHORT TERM...
340 AM CDT

THROUGH WEDNESDAY...

THE VERY HUMID AIR MASS OF YESTERDAY HAS BEEN NUDGED WITH A SHIFT TO
NORTHWEST WINDS...BUT GREATER REPRIEVE FROM THE MUGGY AIR IS ON ITS
WAY BEHIND A COLD FRONT SET TO PASS THIS AFTERNOON. THIS FRONT IS
ASSOCIATED WITH A PRIMARY UPPER LOW CENTER OVER THE CENTRAL GREAT
LAKES AND A SECONDARY SHORT WAVE TROUGH EXTENDING BACK WESTWARD
THROUGH MINNESOTA EARLY THIS MORNING. AS THESE WAVES IN SYNC SLIDE
SOUTHEASTWARD TODAY...ENOUGH UPPER SUPPORT AND MID-LEVEL COOLING
SHOULD BE PRESENT WITH THE SURFACE COOL FRONT BENEATH FOR SCATTERED
SHOWERS AND SOME STORMS DEVELOPING AND MOVING SOUTHWARD. ADDED
FOCUS/CONVERGENCE MAY BE SEEN WITH THE LAKE-ENHANCEMENT OF THE
FRONT...ALTHOUGH BEHIND THIS WIND SHIFT WILL COME LAKE-COOLED AIR AT
THE SURFACE AND SHOULD END THE THREAT FOR THUNDER BY MID AFTERNOON
IN NORTHERN AND LAKE ADJACENT AREAS. MID-LEVEL WINDS WILL BE
STRONGER OVER THE SOUTHERN FORECAST AREA AND MAY ALLOW FOR SOME
SLIGHTLY BETTER STORM ORGANIZATION...OR POSSIBLE CONGEALING OF SOME
COLD POOLS...ALTHOUGH ANY MARGINALLY SEVERE WINDS/HAIL SHOULD BE
BRIEF.

TEMPERATURES ARE VERY LIKELY TO REACH THEIR PEAK BY MID-LATE MORNING
FOR NORTHERN AND LAKE ADJACENT LOCATIONS GIVEN THE TURNING OF THE
WINDS AS WELL AS INCOMING CLOUDS. MOST HIGH-RESOLUTION MODEL
GUIDANCE PAINTS THIS PICTURE AS WELL. LAKESIDE TEMPERATURES SHOULD
FALL INTO THE 60S BY MID AFTERNOON.

TONIGHT AND WEDNESDAY WILL FEEL EVERY BIT OF A DIFFERENT AIR MASS
THAN YESTERDAY AND EVEN THIS MORNING...WITH DEW POINTS FORECAST TO
DROP INTO THE 50S. WITH CONTINUED NORTHEAST WINDS ON
WEDNESDAY...HIGHS ARE EXPECTED TO REMAIN IN THE 70S. CONFIDENCE IS
HIGH IN SUNNY CONDITIONS TOO SO IT REALLY LOOKS LIKE A PLEASANT DAY
ESPECIALLY CONSIDERING THE FREQUENCY OF RAINFALL AND CLOUDS SINCE
THE BEGINNING OF METEOROLOGICAL SUMMER.

MTF

.LONG TERM...
340 AM CDT

WEDNESDAY NIGHT THROUGH MONDAY...

A 595 DM 500MB HIGH ACROSS THE SOUTHERN PLAINS IS FORECAST BY GLOBAL
LONG RANGE GUIDANCE TO SHIFT GRADUALLY NORTHEAST LATE IN THE WEEK
INTO SATURDAY WHICH WILL LEAD TO WARMING TEMPERATURES AND RETURN TO
MUGGY CONDITIONS. AT THE NORTHERN PERIPHERY OF THIS FEATURE WILL BE
THE POSSIBILITY OF DISTURBED WEATHER. ONE KEY SHORT WAVE IMPULSE
WITH COMPACT FORCING ON THE LEADING EDGE OF WARM AIR ADVECTION HAS
BEEN CONSISTENTLY PROJECTED IN GUIDANCE DURING THE THURSDAY/THURSDAY
NIGHT FRAME. CONTINUE TO HAVE POPS SLIGHTLY ELEVATED IN THAT TIME
AND DEPENDING ON HOW THIS EVOLVES COULD PROVIDE AT LEAST A LOOSELY
DEFINED MCS INTO OUR AREA DURING THAT PERIOD. BEYOND...THE SIGNAL
FOR ANY CONVECTION GETS A BIT MORE CHALLENGING FRIDAY AND SATURDAY
AND GFS SOUNDINGS DO WANT TO INDICATE CAPPING LIKELY BY SATURDAY.
GFS/EC BLENDED 850MB TEMPERATURES ARE AT 23C-24C ON SATURDAY WHICH
WOULD STRONGLY SUGGEST 90S IF UNDER SUNSHINE...BUT WE HAVE SEEN HOW
THAT FORECAST WARMTH CAN DISAPPEAR ESPECIALLY IF ANY CONVECTION
BETWEEN NOW AND THEN. THE PATTERN LOOKS PARTICULARLY UNSETTLED IN
RECENT RUNS OF THE LONG RANGE GUIDANCE FOR SUNDAY-MONDAY OF NEXT
WEEK...AS STRONGER AND MORE PROGRESSIVE SHORT WAVE TROUGHS TRACK
EASTWARD AND DAMPEN THE RIDGE.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 09Z...

* SCATTERED SHRA AND A CHANCE FOR TSRA LATE THIS MORNING THROUGH
  EARLY THIS AFTERNOON.

* WIND SHIFT FROM NORTHWEST TO GUSTY NORTH-NORTHEAST IN THE EARLY
  AFTERNOON.

RC

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

COLD FRONT TRAILING FROM SURFACE LOW OVER LOWER MICHIGAN HAS MOVED
ACROSS THE TERMINALS. UPPER LEVEL JET DISTURBANCE IS STILL
GENERATING TSRA ACROSS SOUTHWEST WI AND NORTHWEST IL THAT WILL
MOVE INTO WESTERN APPROACH INTO RFD WITHIN NEXT 2 HOURS. WINDS
WILL SHIFT FROM WEST TO NORTHWEST BY MID MORNING AND THEN A
SECONDARY COLD FRONT AND UPPER LEVEL TROUGH WILL SHIFT ACROSS THE
AREA THROUGH EARLY-MID AFTERNOON. DURING THIS TIME...SCATTERED
SHRA AND A FEW TSRA ARE POSSIBLE...ESPECIALLY NEAR EASTERN
TERMINALS. DUE TO LOWER CONFIDENCE IN DIRECT TERMINAL
IMPACTS...MAINTAINED PROB30. SECONDARY COLD FRONT WILL ALSO SHIFT
WINDS TO GUSTY NORTH-NORTHEAST FOR ORD/MDW/GYY...WITH GUSTS
POSSIBLY APPROACHING OR EXCEEDING 20 KT AT TIMES DURING THE
AFTERNOON AND EVENING UNTIL DIMINISHING LATER IN THE EVENING.
ASIDE FROM ANY POSSIBLE SHRA/TSRA IMPACTS TO VSBY...CONDITIONS
APPEAR FAIRLY LIKELY TO REMAIN VFR.

RC

//ORD AND MDW CONFIDENCE...UPDATED 09Z...

* MEDIUM-HIGH IN SCATTERED SHRA IN AREA LATE MORNING THROUGH EARLY
  AFTERNOON...MEDIUM IN TIMING AND DIRECT TERMINAL IMPACTS...LOW
  IN TSRA.

* HIGH IN WIND TRENDS...MEDIUM IN TIMING OF WIND SHIFT TO NORTH-
  NORTHEAST AND ASSOCIATED SPEEDS AND GUSTS.

RC

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

WEDNESDAY AND THURSDAY...PRIMARILY VFR.

THURSDAY NIGHT AND FRIDAY...SHRA/TSRA POSSIBLE.

SATURDAY...VFR LIKELY.

SUNDAY...SHRA POSSIBLE.  VFR LIKELY.

LENNING

.MARINE...
442 AM CDT

SECONDARY COLD FRONT ASSOCIATED WITH UNSEASONABLY STRONG SURFACE
LOW MOVING INTO THE EASTERN LAKES TODAY WILL SHIFT DOWN THE LAKE
AND RESULT IN A WIND SHIFT TO NORTH AND A QUICK INCREASE IN
SPEEDS. PREVAILING SPEEDS LOOK TO TOP OUT MAINLY IN THE 15 TO 25
KT RANGE WITH GUSTS TO 30 KT LATER THIS AFTERNOON THROUGH MID
EVENING. THE NORTHERLY FETCH DOWN THE LAKE WILL RESULT IN BUILDING
WAVES THROUGH THIS EVENING...FOLLOWED BY A GRADUAL SUBSIDING AS
HIGH PRESSURE SPREADS SOUTHEAST ACROSS THE LAKE AND WINDS DIMINISH
TONIGHT AND ESPECIALLY WEDNESDAY. THE HIGH WILL SLIDE EAST AND A
LOW PRESSURE TROUGH WILL APPROACH FROM THE WEST ON
THURSDAY...RETURNING SOUTHERLY WINDS TO THE LAKE...WITH SPEEDS
INCREASING TO THE 15 TO 25 KT RANGE THURSDAY NIGHT INTO EARLY
FRIDAY. LIGHTER SOUTHERLY WINDS ARE THEN EXPECTED BEHIND THE LOW
PRESSURE TROUGH ON SATURDAY.

HAVE ISSUED A SMALL CRAFT ADVISORY FOR THE ENTIRE ILLINOIS AND
NORTHWEST INDIANA NEARSHORE FROM 4PM THIS AFTERNOON THROUGH
WEDNESDAY MORNING FOR INCREASING NORTHERLY WINDS AND BUILDING
WAVES.
