AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
320 PM CST WED NOV 23 2005

.DISCUSSION FOR AFTERNOON ZONES/GRIDS...

MAIN CONCERNS FOR THIS FORECAST WILL BE ON WINDS TONIGHT INTO
THURSDAY...ALONG WITH NEXT CHANCE OF PRECIPITATION ON FRIDAY.

STRONG SURFACE PRESSURE FALLS ARE NOW WORKING INTO THE OHIO RIVER
VALLEY WITH SURFACE WARM FRONT BEGINNING TO PASS THROUGH NORTHWEST
INDIANA AT THIS TIME. COLD ADVECTION NOW ALREADY UNDERWAY ACROSS
WESTERN PORTIONS OF CWA...ALTHOUGH STRONGER LOW LEVEL CAA LOOKS TO
BE INTO NORTHERN ILLINOIS MORE TOWARD THE 04Z-06Z TIME FRAME AS
SURFACE TROUGH LOCATED ACROSS NWRN WI/ERN MN DROPS INTO THE AREA.
INCREASING MIXED LAYER DEPTH WITH STRONG CAA SHOULD PROMOTE GUSTS
NUDGING UP AGAINST WIND ADVISORY CRITERIA BY LATE THIS EVENING.
SYNOPTIC SCALE SUBSIDENCE WILL ALSO BECOME MORE PRONOUNCED BY 06Z AS
UPPER LOW ACROSS SOUTHERN ONTARIO DROPS INTO LOWER MICHIGAN. WILL
ISSUE WIND ADVISORY FOR LATE THIS EVENING INTO THURSDAY AS SURFACE
LOW CONTINUES TO DEEPEN ACROSS THE NORTHERN LAKES TONIGHT. DEEP
MIXING UP TO 800 HPA STILL APPEARS ON TRACK FOR TOMORROW WITH NAM
PROGS INDICATING 850 HPA WINDS OF 40-45 KNOTS...SO GUSTS INTO THE 40
KNOT RANGE STILL LOOK LIKE A GOOD POSSIBILITY.

STRATOCU IN COLD ADVECTION WILL CONTINUE TO DROP SOUTHWARD THROUGH
THE CWA THIS EVENING. SHOULD SCATTER OUT LOW CLOUDS EARLY THURSDAY
WITH STRONGEST CAA DROPPING SOUTH OF THE AREA. DID NOT MAKE MANY
CHANGES TO INHERITED TEMPS FOR THURSDAY...GENERALLY IN THE MIDDLE
20S BUT NORTHWEST WINDS OF 25 TO 40 MPH WILL SEND WIND CHILLS IN THE
SINGLE DIGITS. ATTENTION THEN TURNS TO FRIDAY...WITH NAM/GFS BOTH IN
AGREEMENT IN TAKING ANOTHER UPPER LEVEL SPEED MAX DOWN BACK SIDE OF
EASTERN CONUS LONGWAVE TROUGH. SOME IMPRESSIVE LOW/MID LEVEL WARM
ADVECTION SHOULD SET UP ACROSS WESTERN MINNESOTA/WESTERN IOWA FRIDAY
AFTERNOON AS SURFACE RIDGE DEPARTS...WITH THIS AREA OF ISENTROPIC
LIFT SPREADING ACROSS NRN IL/SRN WI LATE FRIDAY AFTERNOON INTO
FRIDAY EVENING. DID NUDGE UP CHANCE POPS A BIT NORTH OF I-80 FOR
THIS TIME PERIOD. WILL NEED TO MONITOR THIS TIME PERIOD IN UPCOMING
RUNS GIVEN STRENGTH OF LOW LEVEL BAROCLINIC ZONE AND THE POTENTIAL
FOR SOME ENHANCED BANDING.

UPPER RIDGE BUILDS INTO MS VALLEY FOR SATURDAY AS NEXT PACIFIC UPPER
TROUGH DIGS ACROSS THE SOUTHWEST CONUS. CHANCES OF RAIN WILL
INCREASE SATURDAY NIGHT INTO SUNDAY IN ADVANCE OF THIS TROUGH. THE
ACTIVE PATTERN SHORT WAVE PATTERN WILL CONTINUE INTO EARLY NEXT WEEK
WITH ACTIVE EASTERN PACIFIC SHORT WAVE PATTERN. ALOT OF RUN TO RUN
INCONSISTENCIES IN THE MEDIUM RANGE MODELS REGARDING PHASING WITH
NORTHERN/SOUTHERN STREAMS ACROSS THE WESTERN CONUS EARLY NEXT
WEEK...SO AT THIS POINT DID NOT MAKE MANY DRASTIC CHANGES.

.AVIATION...

DISCUSSION REGARDING 18Z TAFS...

SC DECK BEGINNING TO MOVE SOUTH OUT OF WI AND SHOULD IMPACT
TERMINALS IN THE NEXT HOUR BRINGING MVFR CIGS. AIRMASS DRIES
SOMEWHAT OVERNIGHT IN LOWER LAYERS AS SEEN IN TIME SECTIONS SO SCT
RATHER THAN OVC APPEARS TO BE IN LINE. MORE IMPORTANT FACTOR WILL BE
WINDS. SEVERAL WIND SHIFTS NOTED IN SURFACE DATA WITH TROUGH OVER
LAKE SUPERIOR. FIRST WILL BE TO WEST IN THE NEXT HOURS OR SO. SPEEDS
SHOULD PICK UP SIGNIFICANTLY THIS EVENING AS GUSTS GO TO 35 KTS.
CONINTUED INCREASE IN SPEEDS OVERNIGHT WITH TIGHTENING GRADIENT AND
VERY STRONG CAA. GUSTS TO 40 KTS APPEAR REASONABLE. SHORT WAVES
ROTATING THROUGH UPPER TROUGH FOR REMAINDER OF CYCLE WILL KEEP
GRADIENT TIGHT AND BRING SOME VARITATIONS IN NORTHERLY WIND
DIRECTIONS LATE IN THE PERIOD AS SURFACE REFLECTIONS PASS ACROSS
UPPER MIDWEST
