.DISCUSSION...
356 AM CST

P.S. WITH ALL THE EXCITEMENT TONIGHT FORGOT TO MENTION THAT WILL
BE CANCELLING THE FRZ RAIN ADVISORY EARLY. FRZ DZ HAS ENDED AS
WEAK SFC LOW HAS MOVED INTO SW LOWER MI RESULTING IN WESTERLY
WINDS ADVECTING IN SLIGHTLY DRIER AIRMASS. CIGS HAVE BEEN COMING
UP AND THREAT OF DRIZZLE HAS ALL BUT ENDED FOR NOW. STILL COULD BE
SOME ICY SPOTS WHERE ICE ACCUMULATED AND THE SFC WASNT
TREATED...BUT NOT ANTICIPATING ANY ADDITIONAL FRZ DZ THIS MORNING.

//PREV DISCUSSION...
343 AM CST

OBVIOUSLY THE BIGGEST FORECAST CHALLENGE AND THE MAJORITY OF MY
EFFORT THIS MORNING WAS FOCUSED ON DEALING WITH TONIGHT STORM
SYSTEM. SIGNIFICANT RAINFALL...THUNDERSTORMS...AND MAYBE EVEN SOME
ACCUMULATING WINTRY PRECIP ARE ALL POSSIBLE TONIGHT.

THE PUZZLE PIECES ARE BEGINNING TO FALL INTO PLACE FOR A SIGNIFICANT
STORM SYSTEM TO AFFECT THE CENTRAL AND EVENTUALLY EASTERN UNITED
STATES. VIGOROUS UPPER LEVEL LOW IS MOVING INTO THE FOUR CORNERS
REGION WITH EVEN A FEW THUNDERSTORMS NOTED WITH THIS UPPER
LOW...OFF OF THE CALIFORNIA COAST. FARTHER EAST...HEIGHT FALLS ARE
ALREADY EVIDENT THIS MORNING IN THE ISALLOBARIC ANALYSIS WITH
MODEST PRESSURE FALLS OVER THE CENTRAL PLAINS. AS A RESULT...LOW
LEVEL SOUTHERLY FLOW HAS BEEN INCREASING AND DOING ONE HECK OF A
JOB SENDING MOISTURE STREAMING NORTHWARD...AS EVIDENCED BY THE
LOW/MID 60F DEWPOINTS NOW INTO CENTRAL OKLAHOMA. AS UPPER LOW
CONTINUES EAST A SURFACE CYCLONE WILL DEVELOP OVER THE HIGH PLAINS
THIS MORNING AND BEGIN TO TRACK NORTHEAST TODAY ALONG THE
TIGHTENING BAROCLINIC ZONE BECOMING ESTABLISHED FROM THE CENTRAL
PLAINS NORTHEAST INTO NORTHERN INDIANA.

WHILE MUCH OF THE DAY WILL BE DRY...CONTINUED NORTHWARD TRANSPORT OF
HIGHER THETA-E AIRMASS WILL LIKELY RESULT IN SHOWERS AND
THUNDERSTORMS DEVELOPING THIS AFTERNOON TO THE NORTH OF THE SURFACE
BOUNDARY OVER NORTHERN MO INTO NORTHWEST ILLINOIS...WITH THIS
ACTIVITY LIKELY TO SPREAD INTO OUR CWA TOWARD EVENING. WHILE
INSTABILITY IS NOT EXPECTED TO BE TREMENDOUS...FAIRLY COLD
ENVIRONMENT COULD MEAN A THREAT OF SOME GRAUPEL OR SMALL HAIL WITH
THE MORE VIGOROUS STORMS.

SHOWERS AND THUNDERSTORMS SHOULD INCREASE IN COVERAGE THIS EVENING
AS 60KT+ LOW LEVEL JET TRANSPORTS COPIOUS AMOUNTS OF MOISTURE
NORTHWARD INTO THE REGION. MODELS STILL SUGGEST THAT PWATS WILL
INCREASE TO 250-300% OF NORMAL WITH VERY STRONG LIFT ASSOCIATED WITH
INTENSE FRONTOGENETIC CIRCULATION THAT DEVELOPS BENEATH COUPLED JETS
OVER THE AREA. POTENTIAL EXISTS FOR RESPECTABLY LARGE PORTION OF THE
CWA TO END UP WITH RAINFALL TOTALS WELL OVER AN INCH TONIGHT...WHICH
DOES HAVE ME CONCERNED ABOUT FLOOD POTENTIAL. DID CONSIDER GOING
WITH A FLOOD WATCH...HOWEVER IN THE END DECIDED TO HOLD OFF AS THE
SYSTEM WILL BE MOVING QUITE QUICKLY AND GENERALLY EXPECT RAINFALL
TO END UP BELOW FLASH FLOOD GUIDANCE. OVERALL THINK THERE IS A
RATHER HIGH POTENTIAL FOR MINOR/NUISANCE (ADVISORY TYPE) FLOODING
WITH A MUCH LESSER (THOUGH NON-ZERO) THREAT FOR HIGHER IMPACT
FLOODING.

JUST TO MAKE THINGS MORE INTERESTING...AS SURFACE LOW MOVES QUICKLY
UP THE FRONTAL BOUNDARY...STRENGTHENING NORTHERLY WINDS AND
RESULTANT COLD AIR ADVECTION COULD RESULT IN SOME P-TYPE ISSUES
FROM LATE EVENING INTO THE OVERNIGHT OVER OUR NORTHERN CWA.
FORECAST SOUNDINGS FOR RFD WOULD ACTUALLY SUGGEST A CHANGE OVER TO
FRZ RAIN THEN SNOW BEFORE THE PRECIP ENDS. SYNOPTICALLY
SPEAKING...THIS SCENARIO CERTAINLY DOESNT SCREAM FOR ANY
SIGNIFICANT ACCUMULATIONS OF SNOW/ICE AND AM THEREFORE NOT
INCLINED TO HIT THE THREAT TOO HARD JUST YET AND CERTAINLY NOT
PLANNING ANY WINTER HEADLINES. THIS IS SOMETHING THAT WILL NEED TO
BE WATCHED BUT WITH THE EXPECTED SHARP CUT OFF IN PRECIP ON THE
NORTHERN EDGE OF THE FRONTOGENETIC CIRCULATION AND UNCERTAINTY IN
HOW QUICKLY SUFFICIENTLY COLD AIR MOVES IN...ANY ACCUMULATING
WINTRY PRECIP WILL PROBABLY END UP BEING MORE OF A NOWCAST ISSUE
TONIGHT MORESO THAN A FORECAST ISSUE AHEAD OF TIME.

SPEAKING OF TIGHT THERMAL GRADIENTS...ZFP WILL PROBABLY NOT
ADEQUATELY DESCRIBE EXPECTED TEMPERATURE TRENDS TODAY OVER SOUTHERN
CWA WHERE HIGH TEMPERATURES WILL LIKELY BE REACHED AFTER SUNSET
BEFORE FRONT MOVES IN AND SENDS TEMPS CRASHING BEFORE SUNRISE. WILL
PROBABLY SEE TEMPS WELL INTO THE 50S OVER SOUTHERN MOST CWA FOR A
TIME TONIGHT BEFORE THE BOTTOM FALLS OUT AND TEMPS GO PLUMMETING.

NOT MUCH ELSE WORTH TALKING ABOUT FORECAST-WISE WITH QUICK SHOT OF
COLD AIR MONDAY WITH SKIES CLEARING OUT...FOLLOWED BY A REBOUND IN
TEMPS TUESDAY IN ADVANCE OF A DRY COLD FRONTAL PASSAGE AND
SUBSEQUENT COOL DOWN MID WEEK. PATTERN COULD TURN MORE ACTIVE/WET
AGAIN LATER NEXT WEEK...BUT BEYOND THAT NO POINT IN SPECULATING
ABOUT THE DETAILS THIS FAR OUT AS THE MOST LIKELY THING THAT CAN
SAID WITH COMPLEX SPLIT FLOW PATTERN THAT FAR OUT IS THAT THE MODELS
WILL FLIP FLOP ALL ABOUT AND THE ODDS OF ANYTHING RESEMBLING CURRENT
MODEL GUIDANCE ACTUALLY HAPPENING IS PROBABLY NOT ALL THAT GREAT!

.HYDROLOGY...
343 AM CST

EXPECTING SIGNIFICANT RISES TO OCCUR ON RIVERS AND STREAMS ACROSS
THE HSA FOLLOWING THE ANTICIPATED HEAVY RAINFALL TONIGHT.
CONTINGENCY FORECASTS BASED ON HPC'S FORECASTED QPF SUGGEST THAT
SEVERAL FORECAST POINTS COULD RISE ABOVE BANKFULL...BUT NOT MUCH IN
THE WAY OF FLOODING BASED ON CURRENT QPF. SEVERAL FORECAST MODELS
SUGGEST THAT A SECONDARY AXIS OF HEAVIER QPF...POSSIBLY IN EXCESS OF
AN INCH...COULD SET UP FARTHER NORTH THAN HPC FORECASTS WHICH SUGGESTS
PLACING MUCH HIGHER QPF OVER A MUCH LARGER PORTION OF OUR HSA.
SHOULD THIS OCCUR...RISES ON RIVERS WILL LIKELY BE MORE
SIGNIFICANT WITH AT LEAST MINOR FLOODING AT A FEW OF THE FORECAST
POINTS. RIVER FORECASTS LOOKING AT THE 95TH PERCENTILE MAX QPF
FROM THE SREF SUGGEST THAT MANY FORECAST POINTS WOULD BE
SUSCEPTIBLE TO EXCEEDING FLOOD STAGE WITH A COUPLE FORECAST POINTS
NEARING AND POTENTIALLY EXCEEDING MODERATE FLOOD STAGE.

ENOUGH UNCERTAINTIES EXIST AT THIS POINT TO HOLD OFF ON PUTTING OUT
ANY SORT OF WATCHES...AS A DECENT PERCENT OF THE QPF COULD BE A
RESULT OF THUNDERSTORMS...WHICH WE ARE NOT GREAT AT FORECASTING. IN
ADDITION...TEMPERATURES ARE FORECAST TO FALL BELOW FREEZING MONDAY
MORNING WHICH SHOULD SLOW THE RUN-OFF AND RESULT IN LOWER CRESTS
THAN WOULD NORMALLY BE EXPECTED. UPDATED RIVER FORECASTS ISSUED
LATER THIS MORNING WILL TAKE INTO ACCOUNT THE FORECASTED QPF TONIGHT
AND THOSE WITH INTERESTS ALONG AREA RIVERS SHOULD KEEP ABREAST OF
LATER FORECASTS THE NEXT 48 HOURS.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 15Z...

* LOW POTENTIAL FOR SCT-BKN 010-015 CIGS TO REDEVELOP PRIOR TO
  18-19Z...WILL KEEP FEW010 IN TAF.

* TIMING OF RETURN OF CIGS OF 020-025.

* SOUTH WINDS BECOMING SOUTHEAST THEN EAST.

* TIMING ARRIVAL OF RAIN WITH TS POSSIBLE.

* TRANSITION FROM LIQUID PRECIP TO WINTRY MIX OVERNIGHT.

MDB

//DISCUSSION...UPDATED 15Z...

MADE SOME SIGNIFICANT CHANGES TO CEILING FORECAST INTO AFTERNOON.
008-015 CIGS QUICKLY DISSIPATED FROM ACROSS AREAS SOUTHEAST OF RFD
LEAVING MOSTLY CLEAR SKIES. WITH SUN NOW ALLOWED TO HEAT THE LOWER
LEVELS EXPECT FEW-SCT 010-015 DEVELOPMENT. STRATUS DECK OF 020-025
IS TO THE SOUTH OF THE TERMINALS AND WORKING NORTH...EXPECT THIS
TO ARRIVE EARLY THIS AFTERNOON. RFD LOOKS TO REMAIN IFR FOR
SEVERAL HOURS WITH SOME IMPROVEMENT EXPECTED BY EARLY AFTERNOON.

MDB

PREVIOUS DISCUSSION FROM 12Z...

PERSISTENT DRIZZLE HAS FINALLY COME TO AN END ACROSS THE AREA AND
NOW THE MAJORITY OF THE AREA HAS MVFR TO VFR VISBY NOTED. CIG
TRENDS HAVE BEEN DIFFICULT TO GRASP OVERNIGHT. IFR CIGS HAVE
SLOWLY RISEN TO MID LEVEL MVFR AND THIS SHOULD BE THE TOP FOR THIS
MORNING THOUGH THEY MAY FLIRT WITH VFR FOR A SHORT TIME. SATELLITE
IMAGERY DEPICTS AN AREA OF MID/HIGH LEVEL CLOUDS ABOUT THE I-80
CORRIDOR AND THAT HAS MIXED THE ATMOSPHERE ENOUGH TO TAKE THE IFR
CIGS AND RAISE THEM TO MVFR. IN AREAS TO THE NORTH...WITH LESS
MIXING...CIGS HAVE GENERALLY BEEN IN THE HIGH IFR TO LOW MVFR.
WINDS TO REMAIN FAIRLY LIGHT THROUGH THE DAY THOUGH MIXING MAY
BRING DOWN SOME OF THE SLIGHTLY HIGH MOMENTUM AIR AND GUSTS IN THE
LOW TEENS ARE POSSIBLE...THOUGH SHOULD BE FEW AND BETWEEN. ADDED A
CB GROUP TO THE AFTERNOON AND EVENING PERIOD FOR THE POSSIBILITY
OF SOME SCATTERED THUNDERSTORM ACTIVITY. WINDS TO THEN BECOME
NORTHERLY OVERNIGHT AS SYSTEM PASSES TO THE EAST...AND SUSTAINED
WINDS AS WELL AS GUSTS TO ALSO INCREASE. PRECIP TYPE AS WE MOVE
INTO THE EVENING IS ALSO TRICKY...AS THERE MAY BE A PERIOD WHERE
WE MAY TRANSITION TO FREEZING RAIN / GRAUPEL IF COLD AIR
UNDERCUTS THE WARMER AIR ALOFT...BUT IT WILL EVENTUALLY TRANSITION
TO SNOW BY THE MORNING HOURS.

SHEA

//ORD AND MDW CONFIDENCE...UPDATED 15Z...

* MEDIUM-HIGH CONFIDENCE THAT 010-015 CIGS WILL NOT RETURN UNTIL
  LATER IN THE PERIOD...WILL KEEP FEW010 FOR NOW.

* LOW-MEDIUM CONFIDENCE ON TIMING OF ARRIVAL OF 020-025 CIGS THIS AFTERNOON.

* MEDIUM CONFIDENCE IN WIND TRENDS THROUGH EVENING.

* MEDIUM CONFIDENCE IN TIMING OF ARRIVAL OF RAIN AND THUNDER
  TIMING...MEDIUM-HIGH CONFIDENCE THAT THUNDER WILL OCCUR AT TIMES
  THIS EVENING/EARLY TONIGHT.

* LOW CONFIDENCE ON SPECIFICS OF PRECIP TYPE CHANGEOVER TONIGHT
  BUT CONFIDENCE HIGH IN IT BEING LIGHT SNOW BY MONDAY MORNING.

HIGH PRESSURE ACROSS WISCONSIN AND ILLINOIS...WILL GRADUALLY SHIFT
EAST ACROSS THE LAKES THIS MORNING AND ACROSS THE EAST COAST
TONIGHT. LOW PRESSURE IS BEGINNING TO FORM ACROSS THE PLAINS...AND
WILL MOVE NORTHEAST THROUGH CENTRAL ILLINOIS AND NORTHERN INDIANA
TONIGHT. THE GRADIENT WONT INCREASE MUCH UNTIL THE LOW PUSHES EAST
OF THE LAKES...AND WINDS AOA GALE CRITERIA MAY BE EXPERIENCE
ACROSS THE SOUTHERN HALF OF THE LAKE. CURRENT GUIDANCE STILL
SUGGESTS THAT THIS WILL BE A LOW END GALE EVENT...BUT BEING STILL
3RD PERIOD...WITH A SMALL DECREASE...WITH RESPECT TO INTENSITY...OVER
THE LAST 24 HOURS...WILL CONTINUE TO HOLD ONTO THE WATCH BUT STILL
MENTION GALE FORCE WINDS TO 35 KT IN THE OPEN WATERS FORECAST.
WINDS TO THEN BACK TO THE NORTHEAST MONDAY AFTERNOON AND BEGIN TO
DECREASE AS HIGH PRESSURE ACROSS THE PLAINS BUILDS IN.
