AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
243 AM CST FRI MAR 2 2012

.DISCUSSION...
908 PM CST

THE LATEST TRENDS CONTINUE TO INCREASE THE CHANCES FOR SNOW...AND
IT BEING POTENTIALLY HEAVY ACROSS THE NORTHERN TIER OF COUNTIES.
THE LATEST 00Z NAM HAS ALMOST ALIGNED WITH THE 18Z GFS WITH
RESPECT TO THE RAPIDLY DEEPENING SYSTEM AND OVERALL TRACK...THAT BEING
SLIGHTLY EAST. THE RAPIDLY DEEPENING SYSTEM SHOULD ALLOW THE
ATMOSPHERE TO RAPIDLY COOL AND ALLOW THE CHANGEOVER TO SNOW ACROSS
THE NORTHWESTERN COUNTIES BE QUICK. FARTHER EAST ACROSS MCHENRY
AND LAKE THE ISSUE WILL START WITH HOW QUICKLY TEMPS FALL TO
SUPPORT ALL SNOW. THE NEXT ISSUE REMAINS WITH OVERALL SNOW TOTALS.
THE EARLIER GFS CAME IN WITH OVER ONE INCH OF TOTAL LIQUID QPF
FROM A GENERAL AMBOY TO WAUKEGAN LINE. WHILE LATEST NAM HAS A
SIMILAR QPF AXIS BUT MAINTAINS A GENERAL .5 TO .6 INCH VALUE. 21Z
SREF PROBABILITIES ARE TRENDING TOWARDS A HIGHER SNOWFALL EVENING.
THE MEAN 6 HOUR SNOWFALL OUTPUT HIGHLIGHTS A GENERAL 3-5 READING
ACROSS THE NORTH...INCREASING MORE INTO WISCONSIN AND NORTHERN
MICHIGAN INTO EARLY SATURDAY MORNING. WITH A CONSIDERABLE AMOUNT
OF UNCERTAINTY STILL...DID HOIST A WINTER STORM WATCH FOR
OGLE...WINNEBAGO...BOONE...MCHENRY AND LAKE COUNTIES. THINK THERE
MAY BE SOME LOCATIONS THAT HAVE THE CHANCE TO SEE 5+ INCHES OF
SNOW...WHILE OTHER AREAS SEE THE POTENTIAL FOR CLOSE TO ADVISORY
LEVEL. AS PREVIOUSLY ALLUDED TO IN EARLIER DISCUSSIONS...RAIN WILL
TRANSITION OVER TO A RAIN SNOW MIX AND THEN LIGHT SNOW INTO THE
EVENING HOURS. NO OTHER CHANGES OUTSIDE OF TWEAKS TO THE SNOW GRID
AND HOURLY TEMPS. WILL LET THE OVERNIGHT CREW DIGEST THE LATEST
TRENDS BEFORE UPGRADING OR DOWNGRADING THE WATCH BY THE EARLY
MORNING. UPDATED ZONES AND TEXT PRODUCTS WILL BE OUT SHORTLY.

SHEA

//PREV DISCUSSION...
326 PM CST

AFD...SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT

MAIN FOCUS IS A WIDE RANGE OF IMPACTS FROM A DYNAMIC EARLY SPRING
STORM SYSTEM MOVING ACROSS THE REGION ON FRIDAY...RANGING FROM
THUNDERSTORMS...POSSIBLY SEVERE...ESPECIALLY OVER THE FAR
SOUTHEASTERN CWA COUNTIES TO RAIN CHANGING TO A POSSIBLY
ACCUMULATING SNOW OVER FAR NORTHERN ILLINOIS. FOR A  TIME...THERE
MAY LITERALLY BE TWO SEASONS...WINTER AND SPRING...ONGOING FROM
NORTHWEST TO SOUTHEAST ACROSS THE CWA.

TODAY CAN BE SEEN AS THE CALM BEFORE THE STORM. MAIN CONCERN HAS
BEEN STUBBORN LOW CLOUD DECK AND ITS IMPACT ON TEMPERATURES. LOW
LEVEL MOISTURE UNDER A SHARP NEAR SURFACE INVERSION IS STILL TOUGH
TO ERODE AT THE BEGINNING OF METEOROLOGICAL SPRING. THOUGH THERE WAS
CLEARING FROM THE SOUTHWEST BY THE AFTERNOON...HIGH TEMPERATURES
WERE SUPPRESSED BY THE OVERCAST SKIES.

ATTENTION TURNS TO DEVELOPING ~1003 MB LOW PRESSURE OVER CENTRAL
KANSAS AS OF THE EARLY AFTERNOON...WITH PRESSURE FALLS EXTENDING
INTO WESTERN MISSOURI. APPARENT ON ON WATER VAPOR IMAGERY IS A
STRONG JET STREAM DIGGING INTO DEEPENING BUT TRANSIENT WESTERN
TROUGH AS WELL AS FAST UNDERCUTTING SOUTHERN JET INTO SOUTHWEST.
THIS JET STREAM PHASING WILL SERVE TO QUICKLY DEEPEN MIDLEVEL TROUGH
AND SUBSEQUENTLY SURFACE LOW PRESSURE AS IT TRACKS NORTHEAST TONIGHT
INTO FRIDAY.

STRONG WARM ADVECTION AT H85 AND +1 OR +2 STANDARD DEVIATION ABOVE
NORMAL MOISTURE TRANSPORT FROM SOUTHWEST TONIGHT AHEAD OF DEVELOPING
LOW WILL BEGIN TO PUMP WARM MOIST AIR INTO CWA. ON NORTH END OF THE
NOSE OF WARM ADVECTION/ISENTROPIC ASCENT...A DECENT THERMAL GRADIENT
AND MIDLEVEL FORCING WILL LEAD TO A PERIOD OF LIGHT RAIN OVER FAR
NORTHERN ILLINOIS...LATE TONIGHT INTO THE PREDAWN HOURS OF FRIDAY. I
MAINTAINED LIKELY POPS NORTHERN OGLE TO NORTHERN COOK
LINE...TAPERING TO LOWER CHANCE AND NO POPS FAR SOUTH. SOME CONCERN
WITH FORECAST SOUNDINGS FOR ROCKFORD THAT THERE MAY BE SOME FROZEN
PRECIP MIXING IN...AS THERMAL PROFILE IS PRETTY CLOSE TO FREEZING.
WILL KEEP P-TYPE AS RAIN FOR NOW...BUT THIS MAY BE  SOMETHING TO
MONITOR TONIGHT. OVERSPREADING CLOUD COVER AND INFLUX OF WARMTH AND
MOISTURE WILL KEEP TEMPERATURES UP TONIGHT...WITH MID TO UPPER 30S
FOR MOST OF CWA...POSSIBLY LOW 30S FAR NORTH. I INTRODUCED LOWS
AROUND 40 FOR THE SOUTHERN CWA COUNTIES...WHICH WILL PROVIDE A
SPRINGBOARD FOR THE WARMTH ON FRIDAY THERE.

THE TRACK OF THE SURFACE LOW PRESSURE CENTER AND FEATURES ALOFT WILL
HAVE SIGNIFICANT IMPLICATIONS ON THE EXTENT OF THE THUNDERSTORM
THREAT...AS WELL AS THE WINTER PRECIPITATION THREAT AS WE MOVE
THROUGH THE DAY ON FRIDAY. LATEST NAM RUN STILL SEEN AS A SLIGHTLY
MORE N/W OUTLIER WITH ITS TRACK AS COMPARED TO GFS/ECMWF...WHICH IS
THE BLEND PREFERRED BY HPC. OF NOTE...THOUGH...THE 01.12 GFS AND
ECMWF RUNS HAVE SHIFTED SLIGHTLY WEST OF THEIR EARLIER COUNTERPARTS.
THE 700 MB LOW TRACK ALSO APPEARS TO BE SEVERAL HOURS SLOWER THAN ON
OTHER GUIDANCE...WHICH WILL IMPACT HOW QUICK THE CHANGEOVER TO A
HEAVY WET SNOW OCCURS OVER FAR NRN ILLINOIS....DISCUSSED LATER.

DEFORMATION AXIS WILL HAVE STARTED TO TAKE SHAPE ON NW SIDE OF
CYCLONE BY FRIDAY MORNING...WITH STRONG WARM ADVECTION AND ASCENT
ASSOCIATED WITH THE LOW STARTING TO ARRIVE IN THE FAR SOUTHERN CWA
IN THE MORNING. THUS CONFINED LIKELY POPS TO THE CENTRAL IL COUNTIES
AND THE EASTERN FRINGE OF THE DEFORMATION AXIS OVER FAR NW IL...WITH
CHANCE TO SLIGHT POPS FOR RAIN ELSEWHERE. BROUGHT A CHANCE OF
THUNDER INTO SOUTHERN SECTIONS EARLY ON...BUT BEST THREAT LOOKS TO
BE IN THE AFTERNOON.

***REGARDING SEVERE T-STORM POTENTIAL***

EVEN WITH SLIGHTLY MORE EASTERN TRACK OF LOW FAVORED BY
GFS/ECMWF...THE SOUTHEASTERN PORTION OF THE CWA DOES GET INTO THE
WARM SECTOR OF THE CYCLONE AS IT WRAPS ITS WARM FRONT NORTH BY
FRIDAY AFTERNOON...WITH DEW POINTS SURGING INTO TO THE UPPER 40S AND
EVEN LOW 50S AND AIR TEMPERATURES IN THE UPPER 50S TO NEAR 60 SOUTH
OF A PONTIAC TO RENSSELAER LINE. THERE MAY EVEN BE SOME SURFACE
BASED CAPE TO TAP INTO IN THIS AREA...WHICH WILL NEED TO BE WATCHED
FOR A CONDITIONAL SEVERE THREAT. THIS IS BECAUSE OF THE EXTREME LOW
AND MIDLEVEL WIND FIELDS ASSOCIATED WITH THE SYSTEM...EVIDENT ON ALL
AVAILABLE NWP GUIDANCE. SOUTHWEST JET AT NEARLY 100 KT AT H5/70 KT
AT H7 AND 50 KT AT H85 WILL PUNCH INTO SOUTHEASTERN CWA DURING THE
AFTERNOON. AT THE SURFACE...WINDS WILL BE SOUTHERLY OR
SOUTH-SOUTHEAST...SO THE LOW LEVEL AND DEEP LAYER SHEAR
PROFILES/HODOGRAPHS WILL BE VERY IMPRESSIVE FOR ANY STRONG
THUNDERSTORMS THAT DO GET GOING. LOOKING AT ROUGHLY A EARLY-MID
AFTERNOON TIMING FOR BEST POTENTIAL FOR CONDITIONAL SEVERE THREAT.
THE MAIN CONCERNS WOULD BE FOR ISOLATED TORNADOES...GIVEN THE
PROXIMITY TO THE WARM FRONT AND THE LOW CENTER ADDING ADDITIONAL
LOW LEVEL VORTICITY. STRONG WINDS ARE ALSO A THREAT GIVEN THE VERY
STRONG WIND FIELD ALOFT. I AM CARRYING DEFINITE THUNDER SOUTH OF A
PONTIAC TO VALPO LINE...GIVEN THE FORCING AND LIKELIHOOD OF AT
LEAST ELEVATED INSTABILITY PRESENT.

NORTH OF THE HIGHEST THUNDER THREAT AREA...THE WARM FRONT AT H85
PUSHING NORTH MAY ALLOW FOR ENOUGH ELEVATED INSTABILITY...PLUS
STRONG FORCING...TO ALLOW FOR SOME EMBEDDED THUNDERSTORMS AS FAR
NORTH AS THE CHICAGO METRO EARLY FRIDAY AFTERNOON. HAVE EARLY HIGHS
IN THE 40S TO AROUND 50 NORTH OF I-80...BUT THEY WILL DROP VERY
QUICKLY ONCE THE COLD FRONT SWINGS THROUGH AND STRONG CAA
COMMENCES...SIMILAR TO THE SITUATION WE EXPERIENCED YESTERDAY. THE
NORTHERN ILLINOIS LAKEFRONT WILL LIKELY BE KEPT A BIT COOLER THAN
JUST INLAND WITH EASTERLY WINDS AROUND THE APPROACHING STORM.

**REGARDING ACCUMULATING SNOW POTENTIAL FRI AFTERNOON-EARLY EVE**

AS IS TYPICAL WITH THESE DYNAMIC SPRING SEASON SYSTEMS...THERE WILL
BE THE POTENTIAL FOR A BAND OF MODERATE TO HEAVY CONVECTIVE SNOWFALL
WITHIN THE DEFORMATION ZONE OF THE STORM SYSTEM.

A VIGOROUS MID LEVEL SHORT WAVE IS FORECAST TO TAKE ON A NEGATIVE
TILT AS IT LIFTS ACROSS NORTHERN ILLINOIS LATE FRIDAY AFTERNOON.
THIS WILL INDUCE THE SURFACE LOW TO DEEPEN TO A SUB 990 MB LOW
ACROSS LOWER MICHIGAN DURING THE AFTERNOON ON FRIDAY. A TROWAL LIKE
STRUCTURE LOOKS TO DEVELOP ACROSS FAR NORTHERN ILLINOIS AND SOUTHERN
WI WITHIN THE WARM CONVEYOR BELT TO THE NORTH OF THE SURFACE LOW. IT
WILL BE THIS AREA THAT WILL SEE THE MOST FAVORABLE SETUP FOR A BAND
OF HEAVIER SNOW LATER FRIDAY AFTERNOON AS A BAND OF MID LEVEL
FRONTOGENESIS SETS UP WITHIN THIS TROWAL FEATURE. IT APPEARS
TEMPERATURES WILL BE MARGINAL FOR SNOWFALL INITIALLY...HOWEVER...THE
COMBINATION OF DYNAMIC COOLING AND COLD AIR ADVECTION SHOULD ALLOW
FOR A TRANSITION TO SNOW BY MID AFTERNOON ACROSS THE NORTHWESTERN
SECTION OF MY CWA INCLUDING THE ROCKFORD AREA.

OVERALL...THIS COULD LEAD TO A PERIOD OF HEAVY WET SNOWFALL ACROSS
NORTH CENTRAL ILLINOIS FRIDAY AFTERNOON AND EVENING. THE POTENTIAL
EVEN EXISTS FOR A PERIOD OF CONVECTIVE SNOW AS STRONG FORCING FOR
ASCENT COINCIDES WITH STEEP MID LEVEL LAPSE RATES. BUFFER SOUNDINGS
FROM THE GFS EVEN SUGGEST THE SOME ELEVATED CAPE DURING THE
TRANSITION TO SNOW.

I AM CONCERNED THAT WITH THE ABOVE MENTIONED POTENTIAL FOR A HEAVY
BAND OF SNOW THAT SOME AREAS ACROSS NORTH CENTRAL ILLINOIS MAY
EXPERIENCE A FEW INCHES OF ACCUMULATION WITHIN A FEW HOUR PERIOD
FRIDAY AFTERNOON INTO THE EVENING. IT IS QUIET POSSIBLE IF THESE
INDICATIONS CONTINUE TO REMAIN EVENT IN LATER MODEL RUNS THAT AN
ADVISORY TYPE SNOWFALL COULD OCCUR. I DO NOT HAVE ANY PLANS FOR
HEADLINES AT THE CURRENT TIME DUE TO UNCERTAINTIES ON THE EXACT
CHANGE OVER TIME...WHICH WILL ULTIMATELY HAVE LARGE CONSEQUENCES ON
THE TOTAL AMOUNTS OF SNOW THAT FALL. HOWEVER...I WILL LIKELY
HIGHLIGHT THIS AREA WITH AN SPS THIS AFTERNOON.

KJB

AFTER THE SNOW COMES TO AN END FRIDAY NIGHT AND THE STRONG LOW ZIPS
INTO THE NORTHEASTERN GREAT LAKES...IT WILL BE A PARTLY TO MOSTLY
CLOUDY AND BRISK NIGHT. CAA...WITH H85 TEMPS FALLING TO -7 TO -10C
BY DAYBREAK...WILL ALLOW TEMPERATURES TO FALL INTO THE MID AND UPPER
20S BY MORNING...WITH LOW TEMPERATURES IN DOWNTOWN CHICAGO A BIT
WARMER...IN THE LOW 30S. THE PRESSURE GRADIENT BEHIND THE DEPARTING
LOW WILL REMAIN TIGHT...MEANING BREEZY WESTERLY WINDS THAT WILL
RESULT IN WIND CHILLS POSSIBLY AS LOW AS THE UPPER TEENS BY THE
EARLY MORNING. SATURDAY WILL BE A BRISK AND MAINLY CLOUDY DAY...WITH
H85 TEMPS DOWN NEAR -10C SUPPORTING HIGHS ONLY IN THE MID AND UPPER
30S. WESTERLY WINDS GUSTING OVER 30 MPH WILL ADD TO THE WINTRY FEEL.
FINALLY...VERY STEEP LAPSE RATES AND FORCING FROM VORTICITY LOBES
PIVOTING THROUGH ON WESTERN PERIPHERY OF H5 TROUGH OVER GREAT LAKES
REGION MAY BE ABLE TO TOUCH OFF SOME SNOW SHOWERS AND FLURRIES OVER
THE NORTHERN HALF OF THE CWA...SO WILL MAINTAIN CHANCE POPS
INHERITED FROM PREVIOUS FCST ISSUANCE.

RC

LONG TERM...SUN THROUGH THU

MAIN TROF AXIS SLIDES EAST OF THE AREA SUNDAY BUT MINOR DISTURBANCES
IN COLD CYCLONIC FLOW WILL KEEP EXTENSIVE CLOUD COVER AND THE
POTENTIAL FOR SOME LIGHT SNOW SHOWERS OVER THE AREA SUNDAY. BY
SUNDAY NIGHT INTO MONDAY MORNING...LOW LEVEL FLOW BECOMES NNW AND
GFS SUGGESTING SOME CONVERGENCE OVER LAKE MI. 850 TO LAKE SURFACE
DELTA T LOOKS MARGINAL FOR SNOW BUT BUFKIT INDICATING CAPE AROUND
300 AND EQUILIBRIUM LEVEL UP TO 10-11K FT. WILL CONTINUE CHANCE POPS
FOR LAKE EFFECT SNOW...MAINLY FOR NW IN SUNDAY NIGHT INTO MON
MORNING. BY MIDDAY MONDAY SURFACE RIDGE IS BUILDING INTO THE GREAT
LAKES AND LOW LEVEL FLOW BECOMES MORE NORTHWESTERLY...BRINGING AND
END TO THE LAKE EFFECT THREAT.

MONDAY WILL BE A TRANSITIONAL DAY FROM WINTER BACK TO SPRING AS THE
LARGE SCALE TROF CONTINUES TO SHIFT EAST AND A HIGHLY AMPLIFIED
RIDGE SHIFTS INTO THE CENTRAL US. TUE AND WED LOOK TO BE
UNSEASONABLY MILD AS THE RIDGE AXIS SHIFTS EAST INTO THE GREAT LAKES
AND STRONG SOUTHERLY LOW LEVEL FLOW DEVELOPS OVER THE AREA. HAVE
GONE WELL ABOVE GUIDANCE WITH MID TO UPPER 50S TUE AND UPPER 50S TO
LOWER 60S WED. GUIDANCE BECOMES BIASED BY CLIMATOLOGY ESPECIALLY IN
THE EXTENDED PERIODS. ACTUALLY WOULDNT BE SURPRISED TO SEE TEMPS
WELL INTO THE 60S BY WED. BY THE WAY...RECORDS FOR RFD AND ORD FOR
TUE AND WED ARE 70 AND 78 RESPECTIVELY AND DONT EXPECT ANY THREAT TO
THOSE NUMBERS. THERE MIGHT BE A SLIGHT SE COMPONENT TO THE WINDS ON
TUE WHICH MIGHT LIMIT TEMPS ALONG THE NORTH LAKE SHORE.

NEXT TROF APPROACHES WED NIGHT OR THU...THOUGH LATEST RUN OF GFS
SEEMS TO WANT TO SLOW DOWN THE RETURN OF PRECIP UNTIL THU NIGHT OR
FRI. WILL CONTINUE WITH CHANCE POPS THU FOR NOW. CLOUDS AND SHOWERS
WOULD ALSO HOLD TEMPS TO MID 50S THU BUT IF SLOWER AND DRIER GFS IS
CORRECT WE COULD SEE ANOTHER DAY IN THE 60S.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 08Z...

* ISOLATED LIGHT RAIN SHOWERS/SPRINKLES THROUGH DAYBREAK.

* MVFR CIGS DEVELOPING BY MID-MORNING...DEFINITELY LOWERING
  THROUGH IFR INTO LIFR BY EARLY TO MID AFTERNOON WITH PERIODS OF
  MODERATE RAIN.

* RAIN MIXING WITH SNOW THEN CHANGING TO SNOW LATE THIS AFTERNOON
  WITH SNOW CONTINUING INTO THE EVENING WITH A PERIOD OF MODERATE
  SNOW POSSIBLE.

* EAST WINDS STEADILY TURNING NORTHEAST/NORTH/NORTHWEST THIS
  MORNING THROUGH THE EVENING WITH INCREASING SPEEDS/GUSTS
  THIS AFTERNOON/EVENING.

//DISCUSSION...UPDATED 08Z...

AS OF YET HAVE NOT SEEN ANY OBSERVATIONS OF LIGHT
SHOWERS/SPRINKLES REACHING THE GROUND EARLY THIS MORNING...AND
EVEN IF THEY DO CIGS WILL REMAIN AT VFR IT WOULD APPEAR. HAVE
INCHED BACK THE ARRIVAL OF MVFR AT TAF SITES LATER THIS
MORNING...WITH LOW-LEVEL DRY AIR AND LACK OF SUFFICIENT FORCING
ALOFT LIKELY TO KEEP JUST MID-LEVEL CLOUDS FOR A WHILE. IT STILL
VERY MUCH LOOKS LIKE ONCE CLOUDS ARRIVE THEY WILL DROP FAST IN
PRECIPITATION DURING THE EARLY AFTERNOON. THE TIMING OF RAIN
CHANGING TO A MIX OR ALL SNOW IS GAINING IN CONFIDENCE AT IL TAF
SITES...AS WELL AS THE POTENTIAL FOR A PERIOD OF MODERATE SNOW AT
THOSE FOUR AIRPORTS AS WELL. HAVE INCREASED THE SUSTAINED WINDS AT
CHICAGOLAND AND GYY AIRPORTS THIS EVENING. GYY WILL HAVE WIND
DIRECTLY OFF THE LAKE FOR A BRIEF PERIOD THIS EVENING...WHICH
ACTUALLY CORRELATES TO THE STRONGEST PRESSURE GRADIENT AND
PRESSURE RISE/FALL COUPLET PASSAGE. SO WIND GUSTS UP TO NEAR 40 KT
APPEAR LIKELY DURING THAT PERIOD...ALONG WITH THE POSSIBILITY OF
SOME THUNDERSTORMS.

//PREV DISCUSSION...06Z...

OVERALL...NO SIGNIFICANT CHANGES FROM THE CURRENT TAFS. FORECAST
REMAINS COMPLEX AND DIFFICULT WITH MULTIPLE CHANGES...MANY OF
WHICH WILL OCCUR OVER RATHER SHORT TIME PERIODS.

MID DECK QUICKLY SPREADING ACROSS THE AREA LATE THIS EVENING WITH
SOME RETURNS SHOWING UP ON RADAR. MUCH OF THIS IS VIRGA ALOFT AND
NOT REACHING THE GROUND AND LATEST MODEL GUIDANCE HAS BACKED OFF
REGARDING SHOWER POTENTIAL OVERNIGHT. STILL THE CHANCE OF SOME
SHOWERS BUT OVERALL CONFIDENCE IS DECREASING AND HAVE OPTED TO
CARRY JUST VICINITY MENTION OVERNIGHT INTO FRIDAY MORNING.

A DEVELOPING STORM SYSTEM WILL MOVE NORTHEAST FRIDAY AFTERNOON...
FROM ROUGHLY ST. LOUIS TO SOUTH BEND. THIS STORM WILL STRENGTHEN
ALONG THIS PATH AND CONTINUE TO DEEPEN FURTHER AS IT LIFTS
NORTHEAST TO LAKE HURON FRIDAY EVENING. EASTERLY WINDS OVERNIGHT
WILL TURN NORTHEAST FRIDAY MORNING...NORTH FRIDAY AFTERNOON THEN
NORTHWEST FRIDAY AFTERNOON. AS THESE WINDS STEADILY CHANGE
DIRECTION...THE GRADIENT WILL BE TIGHTENING AND SPEEDS/GUSTS WILL
BE INCREASING. SPECIFIC WIND SPEEDS/GUSTS STILL A BIT UNCERTAIN
BUT CONFIDENCE IS INCREASING THAT A PERIOD OF 30-35KTS...POSSIBLY
HIGHER...WILL MATERIALIZE FROM LATE FRIDAY AFTERNOON INTO EARLY
FRIDAY EVENING. OVERALL DURATION OF THE STRONGEST WINDS MAY ONLY
BE 3 OR 4 HRS...BUT IT WILL REMAIN BREEZY FRIDAY NIGHT AS WINDS
TURN WESTERLY.

AS THIS STORM APPROACHES...EXPECT RAIN TO DEVELOP BY LATE MORNING
OR EARLY AFTERNOON AND BECOME MODERATE TO PERHAPS HEAVY AT TIMES.
AS COLD AIR SPREADS ACROSS THE AREA BY LATE AFTERNOON COMBINED
WITH STRONG UPWARD LIFT...PRECIP WILL LIKELY MIX WITH SNOW THEN
CHANGE TO SNOW...QUICKLY...FIRST ACROSS NORTHWEST IL AND RFD AND
THEN SPREADING SOUTHEAST ACROSS THE CHICAGO AREA TERMINALS.
MAINTAINED OVERALL TREND FROM THE GOING FORECAST BUT TRIED TO
SHORTEN THE DURATION OF MIXED PRECIP. DURATION OF SNOW MAY BE
SHORT LIVED AS WELL...PERHAPS 2-4 HRS...BUT COULD FALL QUITE
HEAVILY DURING THAT TIME PERIOD. STILL PLENTY OF UNCERTAINTY AND
THUS LOW CONFIDENCE. HEAVIEST PRECIP WILL BE EXITING THE AREA BY
MID EVENING WITH LIGHT SNOW PERHAPS LINGERING INTO THE LATE
EVENING HRS.

AS THE LOW LEVELS SATURATE...SOMEWHAT CONFIDENT MVFR CIGS WILL
DEVELOP BY MID/LATE FRIDAY MORNING AND QUICKLY LOWER THROUGH IFR
INTO LIFR AS THE STEADY RAIN SPREADS ACROSS THE TERMINALS. GIVEN
THE UNCERTAINTY REGARDING THE SNOW POTENTIAL/DURATION/INTENSITY...
HAVE LEFT VIS IN THE 3/4SM TO 1SM RANGE BUT THIS MAY END UP BEING
OPTIMISTIC...AS WELL AS IFR CIGS...SHOULD MODERATE OR HEAVY SNOW
MATERIALIZE.

FINALLY...THUNDER IS POSSIBLE EARLY FRIDAY AFTERNOON BUT BEST
CHANCES APPEAR TO BE JUST SOUTH OF THE TERMINALS...HAVE OPTED TO
LEAVE ANY MENTION INCLUDING CB/VCTS OUT OF THIS FORECAST. WOULD
EXPECT DURATION OF ANY THUNDER AT ORD/MDW/GYY TO BE RELATIVELY
SHORT...AN 1 HR OR LESS. CMS

//ORD AND MDW CONFIDENCE...UPDATED 08Z...

* MODERATE CONFIDENCE REGARDING LIGHT RAIN SHOWERS/SPRINKLES
  EARLY THIS MORNING.

* HIGH CONFIDENCE REGARDING CIGS LOWERING TO IFR BY MID
  AFTERNOON....MODERATE CONFIDENCE ON LIFR AND MEDIUM CONFIDENCE
  ON TIMING.

* MODERATE CONFIDENCE REGARDING RAIN CHANGING TO SNOW AT ORD LATE
  THIS AFTERNOON INTO EARLY FRIDAY EVENING...MODERATE CONFIDENCE
  ON TIMING AS WELL AS DURATION/AMOUNTS AND ASSOCIATED CIGS/VIS.

* MODERATE CONFIDENCE ON WIND TRENDS FRIDAY/FRIDAY EVENING.

//OUTLOOK FOR ORD/MDW FOR 12Z SATURDAY-12Z THURSDAY...UPDATED 00Z...

* SATURDAY AND SUNDAY...CHANCE OF MVFR WITH SNOW SHOWERS.
* MONDAY AND TUESDAY...VFR.
* WEDNESDAY...WINDY. CHANCE OF RAIN SHOWERS.
