AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
325 AM CST THU FEB 20 2014

.DISCUSSION...
324 AM CST

POTENTIALLY HIGH IMPACT...MULTIFACETED CYCLONE WILL CONTINUE TO
IMPACT THE REGION THROUGH TONIGHT. POTENTIAL EXISTS FOR HEAVY
RAINFALL (MAINLY THROUGH MID MORNING)...THUNDERSTORMS...A SQUALL
LINE AROUND 00Z THIS EVENING...THEN NON-CONVECTIVE STRONG/LOCALLY
DAMAGING WINDS THIS EVENING.

VERY STRONG LOW LEVEL JET (NEARLY 60KT @ 850MB) CONTINUES TO DRIVE
UNSEASONABLY MOIST AIR NORTHWARD INTO A LOOSELY ORGANIZED MCS
ONGOING OVER EASTERN IA/NORTHERN IL EARLY THIS MORNING. BEEN A
REMARKABLE AMOUNT OF CG LIGHTNING FOR THIS TIME OF YEAR WITH THIS
COMPLEX WITH WSR-88D DATA INDICATING A LOT OF POTENTIAL
GRAUPEL/SMALL HAIL ALOFT WITH THE HIGH DBZ ECHOS...THOUGH SOME OF
THAT COULD ALSO BE WET SNOW FLAKES MELTING.

MCS WILL TRAVERSE THE REGION EARLY THIS MORNING WITH SOME BACK
BUILDING POSSIBLY RESULTING IN PRECIP LINGERING INTO THE 15-18Z TIME
RANGE...BUT THE MAJORITY OF THE HEAVIEST PRECIP LIKELY DONE BEFORE
15Z. SHORT RANGE CONVECTIVE ALLOWING MODELS CONTINUE TO SUGGEST THAT
LOCALIZED RAINFALL TOTALS UP TO AROUND AN INCH ARE POSSIBLE WITH
THIS MCS...PARTICULARLY IN THE VICINITY OF THE I-80 CORRIDOR AND
THIS SEEMS TO BE SUPPORTED BY REGIONAL RADAR TRENDS. NOTE: USE THE
HOURLY AND STORM TOTAL PRECIP PRODUCTS FROM OUR RADAR THIS MORNING
WITH CAUTION...BRIGHT BANDING/GRAUPEL/SMALL HAIL ARE RESULTING IN
INFLATED VALUES BASED ON UPSTREAM SFC OBS.

JUST GET A REPORT OF SOME SPOTTY WET SNOW BETWEEN ELGIN IN RFD BY
WTVO MORNING MET ON HER WAY TO WORK...SO DEFINITELY SEEING SOME
SPOTTY WET SNOW/SLEET/GRAUPEL...BUT ANTICIPATE MOST OF THAT TO
QUICKY TRANSITION TO ALL RAIN AS WARM AIR ADVECTION CONTINUES. TEMPS
ARE MOSTLY IN THE MID 30S AND ALMOST ALL THE ROAD SFC TEMP DATA
SENSORS WE HAVE ACCESS TO SHOW PAVEMENT TEMPS ABOVE FREEZING...SO
ITS LOOKING LIKE WE WILL LARGELY DODGE A BULLET WITH ANY SNOW/ICE
PROBLEMS BRIEF AND CONFINED MOSTLY TO MORE RURAL AREAS OF NC IL.

THE INITIAL SHORTWAVE HELPING ORGANIZING THIS MORNING CONVECTION
SHOULD SHIFT EAST ALONG WITH THE NOSE OF THE LOW LEVEL JET...SO
SHOULD SEE WIDESPREAD AND HEAVIER PRECIP END FROM MID-LATE MORNING
THROUGH MUCH OF THE AFTERNOON. SHOULD STILL BE SOME SCTD/OCNL
SHOWERS IN THE CONTINUED WAA REGIME AS WARM FRONT INCHES NORTH.
DESPITE THE END OF THE HEAVIER MORE WIDESPREAD RAIN BEFORE
18Z...PLAN TO HANG ON TO FLOOD WATCH THRU 21Z TO COVER RUN OFF AND
SNOW MELT PROBLEMS THAT COULD LINGER INTO THE AFTERNOON AFTER THE
HEAVIER RAIN ENDS.

STILL LOOKS LIKELY THAT A STRONGLY FORCED LOW TOPPED LINE OF
CONVECTION WITH LITTLE/NO LIGHTNING ACCOMPANYING THE COLD FRONT WILL
SWEEP ACROSS THE CWA BETWEEN ABOUT 2230Z AND 0130Z. SFC BASED
INSTABILITY IS LIKELY TO BE LACKING...BUT THE EXTREMELY STRONG
FORCING WITH THE VERY DYNAMIC/EXPLOSIVELY DEEPENING SYSTEM STILL
LEAVES ME QUITE CONCERNED ABOUT WIND GUSTS OVER 60 MPH IN SPOTS WITH
THIS SQUALL LINE. IN THE WAKE OF THE SQUALL LINE VERY STRONG
PRESSURE GRADIENT AND IMPRESSIVE PRESSURE RISES WITH MODEST COLD AIR
ADVECTION/STEEP LOW LEVEL LAPSE RATES SHOULD ALLOW FOR A PERIOD OF
VERY STRONG WINDS THIS EVENING. TO PUT INTO PERSPECTIVE JUST HOW
IMPRESSIVE THIS STORM IS...A COLLEGUE AT WPC WHO HAS BEEN DOING WORK
WITH MINIMUM/MAXIMUM MONTHLY PRESSURE TOOK A QUICK LOOK AND INITIAL
FINDINGS INDICATE THAT THIS STORM WILL LIKELY BE THE DEEPEST
FEBRUARY LOW PRESSURE IN THIS REGION SINCE 1902!

HAVE OPTED TO UPGRADE THE HIGH WIND WATCH TO A WARNING FOR THIS
EVENING. NOT CONFIDENT THAT WE'LL MEET STRICT 58MPH GUST CRITERIA
EVERYWHERE...BUT SEEMS LIKELY AT LEAST SOME LOCATIONS WILL GUST TO
AROUND 60 MPH. THE FRINGE BENEFIT IS THAT THIS WARNING SHOULD COVER
ANY BRIEF CONVECTIVE 60+ MPH WIND GUSTS WITH THE LINE OF STRONGLY
FORCED SHOWERS ALONG THE COLD FRONT THIS EVENING AND ALLEVIATE
HAVING TO POTENTIALLY ISSUE SEVERE THUNDERSTORM WARNINGS FOR
LIGHTNING-LESS CONVECTION IF IT DOES END UP PRODUCING SEVERE GUSTS.
VERY STRONG WINDS WILL LIKELY CONTINUE BEYOND THE 05Z SCHEDULED
EXPIRATION TIME OF THE HIGH WIND WARNING...BUT LIKELY MORE IN THE
45-55 MPH RANGE AND FULLY ANTICIPATE THE HIGH WIND WARNING BEING
RAMPED DOWN TO A WIND ADVISORY THIS EVENING.

STRONG WINDS AND SEASONABLY COLD AIR ARE ON TAP FOR FRIDAY AS THE
MASSIVE THEN OCCLUDED CYCLONE FILLS AND GRADUALLY SPINS ITSELF DOWN.
MODELS ARE STILL HAVING FITS HANDLING WEAK SUBTLE WAVES TRACKING
ALONG THE SOUTHERN PERIPHERY OF THE HUDSON LOW...WITH GEM/GFS
HINTING AT SOME LIGHT ACCUMULATING SNOW OVER CENTRAL IL AND OUR
SOUTHERN CWA FRIDAY NIGHT...THEN NAM IS BY ITSELF ALL AMPED UP ABOUT
AN ACCUMULATING SNOW SAT NIGHT (AGAIN SOUTHERN HALF OF CWA)...THEN
ECMWF IS HITTING SNOW CHANCES HARD LATER MONDAY. CERTAINLY PLAUSIBLE
THAT WE COULD POTENTIALLY SEE ONE OR MORE BOUTS OF SOME ACCUMULATING
SNOW INTO EARLY NEXT WEEK...BUT UNTIL WE START TO GET A STRONGER
MORE CONSISTENT SIGNAL IN MODEL GUIDANCE IT IS HARD TO GO VERY HIGH
WITH POPS.

MEDIUM RANGE MODELS CONTINUE TO PAINT AN UNSEASONABLY COLD PICTURE
HEADING INTO NEXT WEEK. ECMWF/GFS BOTH FORECAST H8 TEMPS TO GET INTO
THE 3+ STANDARD DEVIATION BELOW AVERAGE TERRITORY...WHICH IF IT WERE
TO VERIFY COULD RESULT IN TEMPS THREATENING RECORDS BY THE MIDDLE OF
NEXT WEEK. CERTAINLY PLENTY OF TIME FOR MODELS TO BACK ON OF
MAGNITUDE OF THE COLD SOME...BUT THE GENERAL IDEA OF MUCH BELOW
AVERAGE TEMPS HEADING INTO THE LAST WEEK OF METEOROLOGICAL WINTER
LOOKS VERY LIKELY. SOME INDICATIONS ARE THAT THERE COULD BE ANOTHER
ACCUMULATING SNOW THREAT IN/NEAR THE AREA IN ADVANCE OF THE STRONGER
PUSH OF ARCTIC AIR TOWARD THE MIDDLE OF NEXT WEEK...BUT WITH SO MUCH
VARIABILITY OF THE EXACT MODEL DETAILS...THERE IS LITTLE TO HANG
YOUR HAT ON AT THIS TIME.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 06Z...

* WINTRY MIX POSSIBLE AT PRECIP ONSET.

* RAIN AND THUNDER POSSIBLE THIS MORNING...AND POSSIBLE AGAIN IN
  THE AFTERNOON.

* IFR/LIFR CEILINGS.

* STRONG TURNING WINDS.

RODRIGUEZ

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

COMPLEX FORECAST THIS PERIOD WITH SEVERAL ISSUES POSSIBLE TODAY
THROUGH TONIGHT. SYSTEM TO AFFECT THE REGION STILL APPROACHING AT
THIS TIME BUT REMAINING WEST/SOUTHWEST OF THE TERMINALS. THIS
SHOULD CHANGE OVER THE NEXT SEVERAL HOURS AS BETTER FORCING/PRECIP
SPREAD NORTHEAST ACROSS THE AREA. HAVE PRECIP REACHING THE
TERMINALS BY THE 9Z AND 10Z TIME WITH SOME POTENTIAL FOR A WINTRY
MIX OF SNOW/FREEZING RAIN/SLEET AT THE ONSET. ALTHOUGH WITH
SURFACE TEMPERATURES POSSIBLY HOLDING STEADY OR RISING
SLIGHTLY...THE MAIN THREAT COULD END UP ONLY BEING SNOW OR SLEET.
NONETHELESS...THIS WINTRY MIX SHOULD ONLY BE BRIEF BEFORE IT
BECOMES ALL RAIN SOON THERE AFTER. DID ALSO INCLUDE THE MENTION OF
VCTS IN THE TAFS BY 10Z AS STRONG FORCING AND AN INCREASE IN
INSTABILITY MOVE OVER THE TAFS. CONFIDENCE IS LOW WITH REGARDS TO
THE DURATION...BUT COULD EASILY SEE THUNDER TO BE IN AND AROUND
THE TERMINALS FOR A TWO TO THREE HOUR WINDOW. VFR CEILINGS SHOULD
QUICKLY COME DOWN TO LOW END MVFR AND IFR BY THE 12-13Z TIME
FRAME...AND THEN STAY DOWN WITH A TREND TOWARDS LIFR LIKELY.
PRECIP WILL LIKELY CONTINUE THROUGH THE DAY BUT REMAIN ALL
RAIN...WITH THUNDER POSSIBLE ONCE AGAIN IN THE AFTERNOON.

EXPECT SOUTHEAST WINDS TO BECOME MORE EASTERLY AND POSSIBLY
NORTHEAST LATER THIS MORNING...BEFORE TURNING BACK TOWARDS THE
SOUTHEAST AND SOUTH THIS AFTERNOON. WINDS WILL RAMP UP AND BECOME
STRONG IN THE LATE AFTERNOON AND EARLY EVENING...AS THEY TURN
SOUTHWEST.
