AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
347 AM CDT MON APR 9 2012

.DISCUSSION...
338 AM CDT

SHORT TERM...TODAY THROUGH WEDNESDAY...

ANOTHER WARM DRY DAY ON TAP TODAY.  THE PRESSURE GRADIENT WILL BE
STRONG OVERHEAD AS WE ARE BETWEEN A LARGE SURFACE HIGH THAT
STRETCHES FROM BRITISH COLUMBIA TO NEBRASKA AND A LOW PRESSURE
SYSTEM CURRENTLY CENTERED OVER NORTHERN MAINE. A WEAK SURFACE LOW
IS ALSO LOCATED OVER LAKE SUPERIOR THIS MORNING. SIMILAR TO
YESTERDAY...CLEAR SKIES AND VERY DRY AIR WILL ALLOW FOR AMPLE
MIXING. EXPECTING STRONG WINDS ONCE AGAIN...POSSIBLY EVEN
STRONGER THAN YESTERDAY. MAX GUSTS ARE EXPECTED TO BE AROUND 40
MPH. GIVEN THE VERY DRY CONDITIONS...FIRE DANGER IS ALSO A LARGE
CONCERN. MORE ON THAT CAN BE FOUND IN THE FIRE WEATHER DISCUSSION
BELOW. A WEAK COLD FRONT SWINGS THROUGH THIS AFTERNOON BRINGING A
COLDER AIRMASS TO THE REGION. DESPITE THE COLD FRONT...SUBSTANTIAL
MIXING WILL ALLOW MAX TEMPS TO REACH NEAR 60 ALONG THE
WISCONSIN/ILLINOIS STATE LINE TO THE MID TO UPPER 60S SOUTH OF
I-80.

AS THE BOUNDARY LAYER BECOMES DECOUPLED TONIGHT...WINDS WILL
DIMINISH AND TEMPS WILL TUMBLE.  SKIES WILL STAY PRIMARILY
CLEAR WITH HIGH CIRRUS AND COLD AIR STRATUS SETTING UP TO THE
NORTHEAST. WITH THE CLEAR AND CALM CONDITIONS...TEMPS WILL FALL
INTO MID TO LOW 30S. WITH THIS FORECAST DECIDED TO PUT THE
NORTHWEST PART OF THE CWA IN A FREEZE WATCH FOR TONIGHT AS THOSE 5
COUNTIES APPEAR TO HAVE THE GREATEST RISK TO SEE AT LEAST A FEW
HOURS OF BELOW FREEZING TEMPS. NOT ENTIRELY SURE WHEN THE BOUNDARY
LAYER WILL DECOUPLE...AND THE ADDITIONAL MIXING COULD LEAD TO
TEMPS STAYING WARMER LONGER THAN EXPECTED. THEREFORE WITH MARGINAL
CONFIDENCE...KEPT THE FREEZE HEADLINE AS A WATCH.
HOWEVER...DEPENDING ON TRENDS TODAY...MORE COUNTIES COULD BE ADDED
OR THE HEADLINE COULD BE UPGRADED.

TUESDAY AND WEDNESDAY...THE DRY PATTERN CONTINUES AS THE HIGH MOVES
EASTWARD AND PASSES OVER THE CWA WEDNESDAY NIGHT.  GUSTY CONDITIONS
ARE EXPECTED AGAIN ON TUESDAY...HOWEVER NOWHERE NEAR AS GUSTY AS
TODAY.  THE PRESSURE GRADIENT WEAKENS OVERHEAD AND GIVEN THE COLD
AIR MASS...MIXING WILL NOT BE AS EFFICIENT.  MAX GUSTS LESS THAN 30
MPH ARE EXPECTED ON TUESDAY. MAX TEMPS WILL BE BELOW AVERAGE...WITH
ANOTHER ROUND OF BELOW FREEZING TEMPS EXPECTED TUESDAY NIGHT. AS OF
RIGHT NOW...IT APPEARS THAT ALL AREAS AWAY FROM THE LAKE SHORE
WOULD SEE TEMPS AT OR JUST BELOW FREEZING. ANOTHER FREEZING
RELATED HEADLINE MAY BE NEEDED FOR TUESDAY NIGHT. WINDS TRANSITION
TO THE NORTH AND WEAKEN AS THE HIGH APPROACHES ON WEDNESDAY. A
WARMER AIRMASS ACCOMPANIES THE HIGH...WITH TEMPS ON WEDNESDAY MORE
SEASONAL.

LONG TERM DISCUSSION FORTHCOMING...

.FIRE WEATHER...
455 PM CDT

CONDITIONS WARRANTING RED FLAG WARNING PERSISTING LATE THIS
AFTERNOON AS STRONG GUSTY WINDS ASSOCIATED WITH A FAIRLY TIGHT
PRESSURE GRADIENT OVER THE AREA AS WELL AS DEEP MIXING ARE
PERSISTING. ALTHOUGH...WITH THE LOSS OF DAYTIME HEATING...GUSTS
WILL SLOWLY DIMINISH INTO THE EVENING. RELATIVE HUMIDITY VALUES
REMAINING LOW WITH WIDESPREAD VALUES OF AROUND 20 PERCENT
CURRENTLY BEING REPORTED. HIGHER DEW POINT AIR IS TRYING TO WORK
ITS WAY ACROSS NORTHERN ILLINOIS WITH RELATIVE HUMIDITY VALUES
EXPECTED TO RISE THROUGH THE OVERNIGHT HOURS. A MID LEVEL WAVE
PROPAGATING ACROSS THE REGION WILL HELP TO BRING AN INCREASE IN
CLOUD COVER THIS EVENING WITH EVEN AN OUTSIDE POSSIBILITY FOR SOME
SHOWERS. ALTHOUGH...NOT REALLY ANTICIPATING ANY WIDESPREAD
PRECIPITATION OR ANY REAL ACCUMULATIONS. IF ANY PRECIPITATION DOES
DEVELOP...IT WILL BE MAINLY SPRINKLES.

A SIMILAR PATTERN IS EXPECTED ONCE AGAIN ON MONDAY WITH
CONDITIONS EXPECTED TO REACH OR COME CLOSE TO RED FLAG CRITERIA
LATE MONDAY MORNING. STRONG MIXING IS EXPECTED TO PRODUCE GUSTY
WEST NORTHWEST WINDS AND ALSO TO HELP DROP RELATIVE HUMIDITY
VALUES TO AROUND 20 TO 25 PERCENT BY EARLY AFTERNOON. COOLER
TEMPERATURES MAY HELP TO KEEP RELATIVE HUMIDITY VALUES HIGHER IN
SOME LOCATIONS...MAINLY FAR NORTHERN ILLINOIS.
ALTHOUGH...CONDITIONS WILL GET CLOSE TO RED FLAG CRITERIA ACROSS
MOST OF THE AREA...AND EVEN IF THEY DO NOT MEET CRITERIA THE FIRE
DANGER WILL ONCE AGAIN BE HIGH ON MONDAY.

.AVIATION...

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

* STRONG WNW WINDS TODAY.

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

A WEAK AREA OF LOW PRESSURE IS MOVING OVER THE IMMEDIATE AREA VERY
EARLY THIS MORNING AND WILL DEPART BY DAYBREAK. THIS MAY CREATE
SOME SPRINKLES AT THE AIRFIELDS THROUGH 09Z. OTHERWISE...THIS WILL
MAKE FOR A SOMEWHAT DISCOMBOBULATED WIND FIELD THE NEXT FEW HOURS.
WEST NORTHWEST FLOW WILL SETTLE IN QUICKLY AFTER DAYBREAK. SPEEDS
WILL OVERALL BE HIGHER THAN ON SUNDAY WITH AFTERNOON GUSTS OF 27
TO 35 KT VERY LIKELY DUE TO DEEP MIXING. A COLD FRONT MOVING SOUTH
THROUGH THE AREA WILL ALSO HELP. SOME OF THE GUSTS MAY ACTUALLY
HOLD INTO THE EARLY EVENING. WHILE VFR CONDITIONS ARE
EXPECTED...SOME COLD AIR ADVECTION STRATOCUMULUS IS POSSIBLE THIS
EVENING INTO OVERNIGHT FOR CHICAGO AREA AIRPORTS. THESE CLOUDS
SHOULD BE FEW TO SCATTERED AT MOST DUE TO A SOMEWHAT THIN NEAR-
SATURATED LAYER FORECAST.

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

* HIGH CONFIDENCE IN SOME GUSTS REACHING AT LEAST 30 KT THIS
  AFTERNOON.

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

TUESDAY THROUGH THURSDAY...VFR.

FRIDAY AND SATURDAY...CHANCE OF SHRA/TSRA.

.MARINE...
222 AM CDT

LAKE MICHIGAN WILL REMAIN UNDER THE PRESSURE GRADIENT TODAY AND
TONIGHT BETWEEN LOW PRESSURE OVER QUEBEC AND BUILDING HIGH
PRESSURE OVER THE NORTHERN PLAINS. A COLD FRONT WILL SWEEP SOUTH
ACROSS THE LAKE THIS AFTERNOON...TURNING WINDS FROM WEST NORTHWEST
TO MORE NORTHWEST BY EVENING. THE COLD AIR ADVECTION BEHIND THE
FRONT WILL HELP TO BREAK THE TEMPERATURE INVERSION OVER THE LAKE
AND STEEPEN THE LOW-LEVEL LAPSE RATES. WITH THE INCREASED
MIXING...A WIDESPREAD AND PROLONGED PERIOD OF NORTHWEST WINDS NEAR
30 KT ARE GENERALLY EXPECTED TONIGHT THROUGH THE DAY TUESDAY.
OCCASIONAL GUSTS TO NEAR GALE FORCE ARE POSSIBLE. WITH THIS
PERIOD...WAVES WILL GRADUALLY BUILD ESPECIALLY ACROSS THE EASTERN
HALF OF THE LAKE. HIGH PRESSURE WILL THEN PREVAIL OVER THE LAKE BY
LATER WEDNESDAY INTO THE DAY THURSDAY...BEFORE SOUTHERLY FLOW
RESUMES AND SLOWLY INCREASES INTO NEXT WEEKEND.
