AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
339 AM CST SUN FEB 16 2014

.DISCUSSION...

SHORT TERM (TODAY THROUGH TUESDAY NIGHT)...

FORTHCOMING...

LONG TERM (WEDNESDAY ONWARD)...
329 AM CST

NO BIG CHANGES PLANNED FOR EXTENDED FORECAST PERIOD. AFTER THE 12Z
ECMWF TRENDED TOWARD REMAINDER OF GUIDANCE WITH A LESS PHASED
SOLUTION FOR THE THURSDAY SYSTEM...MEANING LESS OF A WARM
UP...THEY TRENDED COOLER WITH TEMPS. WHILE THE ECMWF HAS TRENDED A
BIT STRONGER WITH SOUTHERN STREAM CYCLOGENESIS AND RESULTANT
WARMING...IT IS NO WHERE NEAR AS IMPRESSIVE AS IT HAD BEEN.
GENERAL IDEA WAS TO FOLLOW A GENERAL CONSENSUS OF THE MEDIUM RANGE
MODELS THROUGH FRIDAY...WHICH STILL HAS PERIOD OF WARMING/MELTING
ALONG WITH A POTENTIALLY SIGNIFICANT PRECIP EVENT HERE OR NEARBY.

STRONG WARM AIR ADVECTION WILL BEGIN WEDNESDAY NIGHT AND CONTINUE
INTO EARLY THURSDAY...SENDING MAX TEMPS WITHIN THE COLUMN WELL ABOVE
FREEZING. GIVEN THE DEEP SNOW PACK HERE AND WELL TO OUR
SOUTH...SURFACE TEMPS WILL RESPOND MUCH MORE SLOWLY TO THE WARM AIR
ADVECTION. ABSURD TO GET HUNG UP ON DETAILS THIS FAR OUT AS MODELS
WILL UNDOUBTEDLY VARY THE NEXT COUPLE DAYS WITH THEIR HANDLING OF
THIS SYSTEM...BUT GENERAL SYNOPTIC PATTERN WOULD SUPPORT A POTENTIAL
FOR A PERIOD OF FREEZING RAIN LATER WEDNESDAY NIGHT INTO EARLY
THURSDAY...ESPECIALLY FAR NORTH AND NORTHWEST CWA AND HAVE MAINTAIN
IDEA OF PREVIOUS FORECAST OF SOME MENTION OF FREEZING RAIN.
MAGNITUDE OF THE LOW LEVEL MOISTURE TRANSPORT AND WARM AIR ADVECTION
WOULD ALSO SUPPORT A THREAT OF MODERATE TO HEAVY
RAINFALL...ESPECIALLY OVER SOUTHERN PORTIONS OF THE CWA. GIVEN THAT
THE POSSIBLE SCENARIOS WHERE NO PRECIP OCCURS SEEM TO BE DIMINISHING
HAVE INCREASED POPS ABOVE THE MODEL BLENDED GUIDANCE WEDNESDAY NIGHT
INTO THURSDAY.

CURRENTLY LOOKS LIKE ONLY A BRIEF SHOT OF MODEST COOLING IN THE WAKE
OF THIS SYSTEM BEFORE WESTERN TROUGH RELOADS AND POTENTIALLY SENDS
ANOTHER SYSTEM OUR WAY FOR NEXT WEEKEND. DETAILS ARE VERY SKETCHY
WITH A LOT OF RUN TO RUN AND MODEL TO MODEL VARIABILITY...SO JUST
RAIN WITH CHANCE POPS FOR RAIN OR SNOW FOR NOW.

IZZI

&&

.HYDROLOGY...
339 AM CST

COMPLEX SCENARIO REGARDING FLOOD POTENTIAL LATER THIS WEEK WITH
FAR TOO MANY VARIABLES COMING INTO PLAY TO REALLY HAVE A GOOD IDEA
YET HOW SIGNIFICANT ANY POTENTIAL FLOOD THREAT WOULD BE. ONE TREND
IN THE MEDIUM RANGE MODELS HAS BEEN TOWARD A FAR WEAKER PUSH OF
WARM/MOIST AIR ON THURSDAY...WITH AN INVASION OF 50F DEWPOINTS
LOOKING FAR LESS LIKELY. THE ANTICIPATED WEAKER PUSH OF WARMER
TEMPS/DEWPOINTS WOULD RESULT IN LESS SNOW MELT THAN EARLIER MODEL
RUNS HAD SUGGESTED. DESPITE THIS...THERE STILL IS A POTENTIAL FOR
HEAVY RAINFALL TOTALS...WHICH CURRENT MODEL RUNS SUGGEST WOULD
TARGET OUR SOUTHERN CWA AFFECTING THE IROQUOIS AND KANKAKEE BASINS
THE MOST. A DEEP SNOW PACK CAN ABSORB SOME OF THE RAIN THAT FALLS
AND POTENTIALLY SLOW THE RUN OFF AND SLOW THE RESPONSE TIME OF
RIVERS. THE RISK OF ISOLATED ICE JAM FLOODING DEFINITELY LOOKS
PRETTY HIGH GIVEN THE EXPECTED WARM UP AND INCREASING STREAM FLOW.
WILL FRESHEN UP THE WORDING IN THE ESF THIS MORNING BUT GENERAL
THINKING HAS NOT CHANGED MUCH FROM PREVIOUS ISSUANCES.

&&

.AVIATION...

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

* BORDERLINE IFR/MVFR CIGS LIKELY EARLY THIS MORNING TRENDING TO
  MVFR BEFORE CONDITIONS GO VFR LATER TODAY.

IZZI

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

SNOW IS MOVING AWAY FROM THE TERMINALS BUT ANTICIPATE LOW
CLOUDINESS TO LINGER THROUGH THE NIGHT AND INTO MUCH OF THE DAY
SUNDAY. SOME VARIABILITY EXISTS IN THE CIGS UPSTREAM AND WOULD
EXPECT CIGS LOCALLY TO VARY SOME WITH A GENERAL DOWNWARD TREND
TOWARD LOW END MVFR OVERNIGHT. POTENTIAL EXISTS THAT CIGS COULD
BUILD DOWN TO IFR BUT WOULD LIKE TO MONITOR SHORT TERM TRENDS FOR
A CLEARER SIGNAL BEFORE INTRODUCING INTO TAFS. CIGS SHOULD
DIURNALLY BEGIN TO LIFT SLOW LATER SUNDAY MORNING INTO THE
AFTERNOON...BUT PROBABLY REMAINING MVFR GIVEN SHARP LOW LEVEL
INVERSION IN PLACE. MODELS SUGGEST THAT LOW CLOUDS WILL CLEAR OUT
SUNDAY EVENING AND CONTINUED THIS TREND IN THE TAFS...BUT GIVEN
THE QUICK FLIPPING OF THE LOW LEVEL FLOW BACK TO SOUTHEAST AM
CONCERNED THAT THE LOWER CLOUDS COULD JUST SLOSH BACK NORTHWEST
WITHOUT MUCH CLEARING AT ALL SUNDAY NIGHT. WINDS SHOULD BE NO
STRONGER THAN AROUND 10KT THROUGH THE PERIOD VEERING FROM
SOUTHERLY NOW...TO NORTHWESTERLY OVERNIGHT...TO NORTHEAST BY LATE
SUNDAY AFTERNOON TO SOUTHEAST SUNDAY NIGHT.

IZZI

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

* MEDIUM CONFIDENCE IN OVERALL TRENDS IN CIGS FORECAST BUT LOW
  CONFIDENCE IN PRECISE DETAILS
* LOW CONFIDENCE IN TIMING OF CLEARING OUT OF MVFR CIGS
* HIGH CONFIDENCE IN REMAINDER OF THE FORECAST

IZZI

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

MONDAY...SNOW/IFR LIKELY.

TUESDAY AND WEDNESDAY...PREDOMINANTLY VFR.

THURSDAY...RAIN/FOG/IFR PROBABLE.

FRIDAY...VFR PROBABLE.

.MARINE...
313 AM CST

PROGRESSIVE PATTERN IS EXPECTED TO CONTINUE THE THROUGH MIDWEEK
WITH MULTIPLE SYSTEMS MOVING ACROSS THE LAKE RESULTING IN FREQUENT
CHANGES IN WIND DIRECTION/SPEED. MODEST NORTHERLY WINDS WILL
DEVELOP TODAY IN THE WAKE OF THE DISSIPATING AND DEPARTING TROUGH
OVER THE LAKE THIS MORNING. A PERIOD OF FRESH SOUTHEAST WINDS ARE
EXPECTED VERY LATE TONIGHT INTO MONDAY...WITH SMALL CRAFT ADVISORY
WINDS EXPECTED FOR THE NEARSHORE AND POSSIBLY A FEW GUSTS NEAR
GALE FORCE OVER THE NORTHERN/CENTRAL PORTIONS OF THE OPEN LAKE.
BRIEF LULL IN THE WINDS MONDAY NIGHT BEFORE SOUTH TO SOUTHEAST
WINDS CRANK UP AGAIN TUESDAY...WITH FORECAST SOUNDINGS NOW
SUPPORTING A PERIOD OF GALE FORCE WINDS OVER NORTHERN PORTIONS OF
THE LAKE.
