AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL

.DISCUSSION...
404 AM CDT

330 AM CDT

SHORTER TERM FORECAST HIGHLIGHTS/CHALLENGES ARE POTENTIAL FOR
SHOWERS CLIPPING NE IL EARLY THIS MORNING...HEAT TODAY THROUGH WED
AND STRONG WINDS LATER TODAY. THEN...FURTHER OUT INTO THIS WEEK IS
CHANCES FOR THUNDERSTORMS WITH A COOL FRONT PASSING ACROSS THE AREA
LATER WED THROUGH THU WITH TEMPS COOLING OF FROM LOW-MID 90S TO
LOW-MID 80S FOR THU AND FRI /COOLER NEAR THE LAKE/ BEFORE TEMPS TO
CLIMB BACK TO UPPER 80S FOR THE WEEKEND.

STRONG WARM AIR ADVECTION HAS BEEN ONGOING FROM THE CENTRAL PLAINS
NE TO THE UPPER MIDWEST AND WESTERN GREAT LAKES THROUGH THE NIGHT.
00Z RAOBS MEASURED 850HPA TEMPS 21-23C FROM TOP N TO ABR...WHILE A
LITTLE FURTHER W TEMPS OF 27-32C FROM AMA N TO LBF. STRONG THETA-E
ADVECTION SPREADING W TO E ACROSS WI EARLY THIS A.M. AS NOSE OF
40-55KT SOUTHERLY LLJ PUNCHES ACROSS THE UPPER MIDWEST AND SUSTAINS
CONVECTIVE COMPLEX OVER THE U.P. AND WI MOVING E INTO THE GREAT
LAKES AHEAD OF A SHORT WAVE TROUGH OVER WESTERN ONTARIO...THE MN
ARROWHEAD AND NW WI. ALONG S CENTRAL AND SE WI WHERE FORCING IS NOT
AS STRONG A A BIT FURTHER N SHOWERS HAVE PERSISTED AND MOVED EASTWARD
N AND JUST ALONG THE WI-ILL STATE LINE. THE LEADING EDGE OF THESE
SHOWERS WAS REACHING THE LAKE SHORE AT PREDAWN. A SLIGHT CHANCE OF
SOME SHOWERS INTO EXTREME NE IL OVER THE NEXT COUPLE HOURS OTHERWISE
LITTLE IF ANY CHANCE OF ANY RAIN TODAY.

WITH THE STRONG PUSH OF VERY WARM AIR FROM THE PLAINS BACK ACROSS
THE LOCAL AREA AND THE LOW LEVEL THERMAL RIDGE TO BE OVER OF JUST N
OF THE LOCAL AREA THIS AFTERNOON...MID 90S A GOOD BET GIVEN 850HPA
TEMPS PROGGED IN THE 20-21C RANGE. WITH 1 TO 2KM AGL WINDS FROM THE
SW AT AROUND 30KT THIS MORNING INCREASING TO 35-45KT FOR THIS
AFTERNOON...AND STRONG SURFACE HEATING AS CIRRUS CLOUD COVER MOVES
OFF TO THE E LATER THIS MORNING...EXPECT STRONG GUSTY WINDS BY
MIDDAY. TIGHTEST SURFACE GRADIENT AND RESULTING LOWER LEVEL WINDS
DEPICTED BY MODELS TO BE OVER N CENTRAL AND FAR NE IL LATER TODAY.
THIS IS WHERE WIND/WIND GUSTS LIKELY TO MEET WIND ADVISORY CRITERIA
SO HAVE ONE OUT FOR THESE AREAS FORM 18Z TO 00Z. STOUT WINDS...
THOUGH NOT AS STRONG AS TODAY/S...EXPECTED AGAIN TUE AS THE UPPER
LOW CURRENTLY JUST W OF VANCOUVER ISLAND AND THE ASSOCIATED SURFACE
LOW TRACK E ACROSS THE ROCKIES LATE TODAY AND TONIGHT...CONTINUING
ACROSS THE NORTHERN PLAINS TUE BEFORE TURNING NORTHEASTWARD INTO
SOUTHERN MANITOBA AND SW ONTARIO BY WED MORNING.

THE LOW LEVEL THERMAL RIDGE WILL LIFT FURTHER N FOR TUE THOUGH
AFTERNOON TEMPS TO NOT BE MUCH DIFFERENT FOR TUE AS SEEN TODAY.

.FIRE WEATHER...
445 PM CDT

THERE WILL BE ELEVATED FIRE WEATHER RISK ON MONDAY AND TUESDAY.

TEMPERATURES IN THE MID 90S ARE EXPECTED TO RETURN TO THE AREA
FOR MONDAY AND TUESDAY. STRONG SOUTHWEST WINDS ARE ALSO EXPECTED TO
ACCOMPANY THIS HEAT BOTH DAYS. WINDS ARE EXPECTED TO GUST TO AROUND
40 MPH ON MONDAY...WITH SLIGHTLY WEAKER WINDS EXPECTED ON TUESDAY.
SOME UNCERTAINTY REMAINS ON HOW LOW DEW POINTS WILL FALL DURING
BOTH AFTERNOONS WITH RECENT HEAVY RAINFALL AND SUBSEQUENT INCREASES IN
SOIL MOISTURE COMPLICATING THE PICTURE. HOWEVER...IT IS POSSIBLE THAT
THE STRONG WINDS COMBINED WITH DEEP LAYER MIXING WILL AID DRYING AND
DEW POINTS MAY FALL INTO THE LOWER 60S ON MONDAY...AND POSSIBLY THE
UPPER 50S ON TUESDAY. IF THE DEW POINTS DO FALL TO THESE VALUES...
THIS WOULD RESULT IN MINIMUM RELATIVE HUMIDITY VALUES BETWEEN ON THE
MID 30S PERCENT ON MONDAY AFTERNOON AND UPPER 20S TO LOWER 30S PERCENT
ON TUESDAY. SO...THERE WILL BE ELEVATED FIRE WEATHER RISK FOR
BOTH DAYS...AND DEWPOINT TRENDS WILL NEED TO BE MONITORED CLOSELY
IN CASE A RED FLAG WARNING MAY BE NEED TO BE ISSUED.

.AVIATION...

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

* POSSIBLY A FEW SHOWERS WITHIN THE NORTHERN VICINITY OF ORD.

* SW WINDS AROUND 35 KT AT 1500-2000 FT AT DAYBREAK.

* STRONG SSW WINDS AT SURFACE GUSTING TO 35 KT THIS AFTERNOON.

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

WITH DEEP LOW PRESSURE OVER THE HIGH PLAINS...A STRONG PRESSURE
GRADIENT HAS ESTABLISHED ITSELF OVER THE UPPER MISSISSIPPI VALLEY
AND WESTERN GREAT LAKES REGION. SW WINDS ARE ALREADY ON THE
INCREASE ALOFT AND WILL FOLLOW SUIT FROM THE SURFACE AT A SSW
DIRECTION TODAY. WITHIN THE WARM AIR ADVETION REGIME ALOFT...SOME
ISOLATED TO SCATTERED SHOWERS WILL LIKELY PERSIST NEAR THE IL/WI
BORDER EARLY THIS MORNING. THE BULK OF THE CONVECTIVE ACTIVITY IN
MN AND WESTERN WI IS EXPECTED TO REMAIN IN CENTRAL WI EARLY THIS
MORNING...MAYBE REACHING DOWN INTO SE WI BY MID-MORNING. SOME
DEBRIS VFR CLOUDS ARE POSSIBLE FROM THIS...BUT SUNNY CONDITIONS
ARE EXPECTED BY AFTERNOON WHICH WILL FURTHER ENHANCE MIXING FOR
STRONG WINDS. GUSTS IN EXCESS OF 30 KT ARE LIKELY BY LATE MORNING
/~16Z/ AT MOST TAF SITES...ESPECIALLY RFD. GUSTS AT RFD MAY EVEN
REACH 40 KT THIS AFTERNOON. DURING THE EVENING TONIGHT SPEEDS WILL
DIMINISH...BUT GUSTS WELL OVER THE SUSTAINED SPEEDS TO AROUND 30
KT WILL STILL BE LIKELY DURING THE EARLY TO MID EVE.

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

* WHILE LLWS CRITERIA APPEARS UNLIKELY TO BE MET...HIGH
  CONFIDENCE THAT SW WINDS ALOFT AT 1500-2000 FT WILL BE AROUND 35
  KT NEAR DAYBREAK THIS MORNING.

* HIGH CONFIDENCE IN SURFACE WIND TRENDS WITHIN THE TAFS THROUGH
  00Z. MEDIUM CONFIDENCE DURING THIS EVENING.

//OUTLOOK FOR ORD/MDW FOR 12Z TUESDAY-12Z SUNDAY...UPDATED 00Z...

TUESDAY AND WEDNESDAY...VFR. GUSTY SSW WINDS. VERY HOT/HIGH
DENSITY ALTITUDES.

WEDNESDAY NIGHT AND THURSDAY...CHANCE TSRA.

FRIDAY AND SATURDAY...VFR.

MTF/IZZI

.MARINE...
400 AM CDT

LOW PRESSURE IS MOVING EAST ALONG THE INTERNATIONAL BORDER WITH
THE HIGH PLAINS THIS MORNING...SETTING UP A STRONG PRESSURE
GRADIENT OVER THE LAKE. WARMING WATER TEMPERATURES WILL ALLOW THE
MARINE STABLE LAYER TO HAVE ONLY LIMITED INFLUENCE AT MINIMIZING
THE WINDS TODAY. GALES LOOK TO BE A GOOD BET ACROSS THE NORTHERN
HALF OF THE LAKE AND ALONG THE IL AND FAR NW IN NEARSHORES WHERE
STRONG OFFSHORE FLOW IS IN PLACE. IN ADDITION...A SLOWLY DECAYING
STORM COMPLEX WILL MOVE EASTWARD ACROSS THE CENTRAL PART OF THE
LAKE THIS MORNING. SOME OCCASIONAL HIGH GUSTS ARE LIKELY WITHIN
THIS. AS THE LOW WORKS NORTHEAST AWAY FROM THE LAKES...THE WINDS
WILL VERY SLOWLY DIMINISH TONIGHT...ESPECIALLY ACROSS NEARSHORE
AREAS. ANOTHER LOW PRESSURE AREA WILL DEVELOP FROM THE HIGH PLAINS
NORTHEASTWARD FROM TUESDAY INTO WEDNESDAY. THIS WILL KEEP SOUTH TO
SOUTHWEST WINDS UP OVER THE LAKE...MOST OF THAT TIME BEING WITHIN
THE 20 TO 30 KT RANGE. THIS LOW WILL SWING A COLD FRONT EAST
ACROSS THE LAKE DURING WEDNESDAY NIGHT...BRINGING AN END TO THE
HIGHER WIND PERIOD.
