AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1048 PM CST WED JAN 27 2016

.UPDATE...
759 PM CST

FORECAST LARGELY IN GOOD SHAPE. DID UPDATE GRIDS TO REFINE CLOUD
COVER TRENDS A BIT. MAIN BAND OF MID-HIGH CLOUDS AND ASSOCIATED
VIRGA WILL EXIT THE AREA THIS EVENING WITH A PERIOD OF CLEARING
BEFORE POST FRONT STRATOCUMULUS LIKELY ARRIVES LATE EVENING INTO
THE OVERNIGHT FROM THE NORTHWEST. REMOVED THE SLIGHT CHANCE POPS
AS LOW LEVEL DRY AIR HAS BEEN JUST TOO MUCH FOR THE VIRGA TO
OVERCOME AND HAVEN'T SEEN ANY PRECIP REPORTS EAST OF THE MS
RIVER. IF A FLAKE OR ICE PELLET OR TWO DOES MAKE IT TO THE GROUND
OVER THE SE HALF OF THE CWA IN THE NEXT HOUR OR TWO IT SHOULD ONLY
BE A TRACE OF NO SIGNIFICANCE. STRONG/GUSTY SOUTHWEST WINDS WILL
LIKELY HOLD TEMPS LARGELY STEADY THROUGH THE NIGHT.

IZZI

&&

.SHORT TERM...
212 PM CST

THROUGH THURSDAY...

A CLIPPER SYSTEM OVER FAR SOUTHWESTERN ONTARIO...WILL SHIFT EASTWARD
ACROSS THE UPPER GREAT LAKES TONIGHT INTO THURSDAY. STRONG SURFACE
PRESSURE FALLS AROUND 10 MB/6HRS IN ADVANCE OF THIS LOW WILL LEAD
TO AN INCREASE IN SOUTH-SOUTHWESTERLY WINDS OVER THE AREA THIS
EVENING. BECAUSE OF THIS...THE WINDS OVER THE AREA WILL LIKELY BE
GUSTY...AND BE THE STRONGEST THIS EVENING. WARM AIR ADVECTION WILL
LIKELY DRIVE AN AREA OF SNOW TONIGHT...BUT IT APPEARS THE BETTER
MOISTURE WILL REMAIN NORTHEAST OF THE AREA. THEREFORE...IT APPEARS
THAT NO MORE THAN A FEW LIGHT SNOW SHOWERS WILL IMPACT
FAR NORTHEASTERN ILLINOIS TONIGHT.

TEMPERATURES ACROSS THE AREA TONIGHT WILL LIKELY NOT DROP MUCH...IF
AT ALL TONIGHT AS SOUTHWEST WINDS AND WARM AIR ADVECTION KEEP LOWS
NEAR THIS AFTERNOONS HIGH TEMPERATURES. ON THURSDAY A COLD
FRONT...ASSOCIATED WITH THE CLIPPER SYSTEM...IS EXPECTED TO DROP
ACROSS THE AREA IN THE AFTERNOON. THIS SURFACE FRONT ALSO LOOKS TO
BE ACCOMPANIED BY A MID LEVEL DISTURBANCE...WHICH WILL BE DIGGING
SOUTHEASTWARD OVER THE AREA. GIVEN THAT THE LOW LEVEL LAPSE RATES
ARE EXPECTED TO STEEPEN WITH THE COLD FRONTAL PASSAGE...IT APPEARS
THAT SOME SNOW SHOWERS WILL DEVELOP OVER THE AREA IN THE LATE
MORNING AND INTO THE AFTERNOON. OVERALL...THIS LOOKS LIKE A QUICK
HITTING LIGHT SNOW EVENT...BUT A DUSTING TO A HALF INCH OF SNOW IS
POSSIBLE WITH THIS ACTIVITY BEFORE IT ENDS BY EARLY EVENING.

KJB

&&

.LONG TERM...
333 PM CST

THURSDAY NIGHT THROUGH WEDNESDAY...

SYNOPSIS...A SIGNIFICANT WARM-UP IS EXPECTED OVER THE WEEKEND.
FOCUS NEXT WORK WEEK CONTINUES TO BE ON WHAT WILL LIKELY BE A
SIGNIFICANT STORM SYSTEM TRACKING FROM THE SOUTHERN PLAINS TO THE
MIDWEST..

ANY LINGERING SNOW SHOWERS WILL SHIFT INTO NORTHWEST INDIANA
BEFORE ENDING THURSDAY NIGHT. BRIEF DRIER HIGH PRESSURE RIDGING
WILL MOVE OVER THE AREA...SO WITH SOME CLEARING/PCLOUDY SKIES
OVERNIGHT...LOWS IN UPPER TEENS TO AROUND 20 ARE FAVORED IN
TYPICAL COOL SPOTS NORTH OF I-80...WITH LOW TO MID 20S ELSEWHERE.
DID LOWER MINS A BIT FROM PREVIOUS FORECAST CLOSER TO BUT NOT AS
COLD AS MOS GUIDANCE.

ANOTHER CLIPPER PASSING TO THE NORTH WILL LIFT A WARM FRONT
ACROSS THE AREA ON FRIDAY. WARM ADVECTION AND DEVELOPING SOUTHERLY
SURFACE FLOW WILL ENABLE RECOVERY TO MID 30S TO AROUND
40...WARMEST ALONG/WEST OF A STERLING TO PAXTON LINE. A FEW LOW
30S ARE EXPECTED NEAR THE WI STATE LINE. FRIDAY NIGHT WILL BE
BREEZY AND MILD TEMPS FOR LATE JANUARY IN WARM SECTOR OF THE
CLIPPER...WITH A MINIMAL TEMP DROP AT MOST. SW WIND GUSTS COULD
REACH 25-30 MPH. A FAIRLY STOUT SHORTWAVE ASSOCIATED WITH THE
CLIPPER WILL MOVE OVER THE AREA OVERNIGHT AS TRAILING COLD FRONT
APPROACHES. FORECAST SOUNDINGS APPEAR FAIRLY DRY...SO FOR NOW HAVE
KEPT PRECIP MENTION OUT OF NORTHERN CWA...BUT WILL NEED TO
MONITOR.

OVER THE WEEKEND...A VERY STRONG EL NINO ENHANCED JET STREAK WILL
MOVE ASHORE ONTO THE PACIFIC COAST...WITH AN ACCOMPANYING MIDLEVEL
TROUGH DIGGING OVER THE SOUTHWEST RESULTING IN BROAD HEIGHT RISES
AND MILD CONDITIONS OVER OUR REGION. SOUTHWEST FLOW AND WAA WILL
QUICKLY RETURN ON SATURDAY AFTER WEAK COLD FROPA AND NOT EXPECTING
LOW CLOUDS TO LIMIT WARMING POTENTIAL. CLIMO OF PROGGED 850/925 MB
TEMPS SUPPORT HIGHS OF AT LEAST 45-50...WITH MORE SOLIDLY LOW 50S
DISTINCTLY POSSIBLE ESPECIALLY IN SOUTHERN CWA.

ATTENTION ON SUNDAY IN TERMS OF PATTERN EVOLUTION INTO NEXT WEEK
WILL FOCUS ON STRENGTH OF A NORTHERN STREAM MIDLEVEL WAVE MOVING
INTO THE WESTERN GREAT LAKES...WITH DEEPENING SFC LOW MOVING
NORTHEAST FROM LAKE MICHIGAN. VERY MILD START TO SUNDAY WILL
SUPPORT MID 40S TO LOWER 50S FOR HIGHS...WARMEST SOUTH OF I-80.
GFS IS STRONGEST WITH SHORTWAVE AND FORCING FROM IT AHEAD OF COLD
FRONT SHOULD CAUSE ISOL'D TO SCT'D LIGHT RAIN/SHOWERS TO BREAK
OUT.

ENSEMBLES AND OPERATIONAL GUIDANCE CONTINUE TO STRONGLY SUPPORT A
SIGNIFICANT STORM SYSTEM TRACKING FROM THE SOUTHERN HIGH PLAINS TO
THE MIDWEST MONDAY NIGHT THROUGH TUESDAY NIGHT. THIS WILL BE IN
RESPONSE TO IMPRESSIVE SOUTHERN UPPER JET AND DIGGING MID/UPPER
TROUGH INTO THE SOUTHWEST. WE'RE STILL A LONG WAYS OFF FROM THIS
SYSTEM AFFECTING THE AREA...SO THERE REMAINS SUBSTANTIAL SPREAD
WITH RESPECT TO TRACK....STRENGTH AND TIMING OF THE LOW PRESSURE
SYSTEM AND ASSOCIATED MID/UPPER FEATURES. ASSESSING PREVIOUS 2
DAYS OF MODEL RUNS...BELIEVE THAT THE SUNDAY WAVE BEING STRONGER
COULD PLAY A ROLE IN A BETTER COLD SUPPLY/FARTHER SOUTH BAROCLINIC
ZONE IN ADVANCE OF THE PRECIP SPREADING NORTHWARD LATE MONDAY
NIGHT/EARLY TUESDAY. IN ADDITION...COOL DRY HIGH PRESSURE WILL BE
IN PLACE NORTH OF THE GREAT LAKES REGION.

STRONG SOUTHWEST SYSTEMS SUCH AS THIS ONE WILL LIKELY BE WITH
GUIDANCE SHOWING TENDENCY FOR CLOSING OFF AT MID-LEVELS OFTEN
TRACK SLOWER IN REALITY THAN PROGS SEVERAL DAYS OUT. IF THERE IS
ENOUGH COLD AIR IN PLACE...COULD BE A SWATH OF ACCUMULATING
SNOW/SLEET IN WAA PRECIP ON TUESDAY...BUT A FARTHER NORTH
BAROCLINIC ZONE AND WAVE CLOSING OFF FARTHER WEST COULD QUICKLY
FLOOD WARM AIR NORTHWARD AND RESULT IN MAINLY RAIN. OF
COURSE...STILL A SCENARIO IN WHICH WAVE DIGS FAR ENOUGH SOUTHEAST
TO GET US IN THE PRIMARILY WINTRY ZONE. IT'S FAR TOO EARLY FOR
MUCH IN WAY OF SPECIFICS NONETHELESS...AND POTENTIAL SCENARIOS
RANGE FROM A SWATH OF HEAVY SNOW SOMEWHERE IN THE CWA TO A WINTRY
MIX TO RAIN TO HEAVY RAIN AND EVEN T-STORMS AND FLOODING. WIDE
OPEN GULF WILL RESULT IN IMPRESSIVE MOISTURE TRANSPORT...AND
MODERATE TO HEAVY PRECIP CONTINUES TO BE A GOOD BET WHATEVER THE
TYPE. FOR NOW...IN MONDAY NIGHT THROUGH TUESDAY NIGHT
PERIOD...HAVE GENERALLY GONE WITH RAIN/SNOW IN WEATHER GRIDS. WITH
A STRONG SFC LOW EXPECTED...THERE WILL ALSO BE PERIODS OF
STRONG/GUSTY WINDS AT TIMES AS WELL. COLDER AIR WILL RETURN ON
BACKSIDE OF SYSTEM ON WEDS...WITH ANY PRECIP FAVORED TO BE IN FORM
OF SNOW. STAY TUNED.

RC

&&

.AVIATION...FOR THE 06Z TAFS...

COLD FRONT WILL MOVE THROUGH THE TERMINALS OVERNIGHT WITH WINDS
VEERING TO MORE WESTERLY DIRECTION AND LIKELY REMAINING SOMEWHAT
GUSTY THROUGH THE NIGHT. MID-HIGH CLOUDS ARE MOVING OUT OF THE
AREA NOW AND LATEST SATELLITE TRENDS ARE LOOKING MORE AND MORE
LIKE THE STRATOCUMULUS OVER WISCONSIN WILL LARGELY STAY TO OUR
NORTH OVERNIGHT. SECONDARY COLD FRONT WILL PASS THURSDAY CAUSING
WINDS TO VEER MORE NORTHWESTERLY WHICH SHOULD HELP PULL THE MVFR
CIGS DOWN. SOME GUIDANCE CONTINUES TO HINT AT THE POSSIBILITY OF
SOME FLURRIES OR LIGHT SNOW SHOWERS THURSDAY AFTERNOON AND HAVE
MAINTAINED PROB30 TO COVER THIS POTENTIAL. CIGS WILL PROBABLY
PERSIST INTO AT LEAST THE FIRST HALF OF THURSDAY NIGHT BUT WITH
SOME TENDENCY TO LIFT TOWARD LOW END VFR EXPECTED.

IZZI

&&

.MARINE...
401 PM CST

A VERY ACTIVE PERIOD ON THE LAKE WITH SERIES OF FAST MOVING LOW
PRESSURE SYSTEMS MOVING NEAR OR NORTH OF THE LAKE THROUGH SUNDAY.
THEN TUESDAY NEXT WEEK...A POWERFUL STORM SYSTEM WILL LIKELY CAUSE
A PERIOD OF STRONG WINDS.

GALES UP TO 40-45 KT ARE EXPECTED TONIGHT AS A CLIPPER PASSES
NORTH OF THE LAKE...WITH SMALL CRAFT CRITERIA WINDS IN THE
NEARSHORE. BEHIND THE COLD FRONT TRAILING FROM THE LOW
PRESSURE...ANOTHER PERIOD OF NORTH-NORTHWEST GALES IS EXPECTED
LATE THURSDAY AFTERNOON THROUGH THURSDAY EVENING FOR THE NORTH 1/3
OR HALF OF THE LAKE. HAVE ISSUED A GALE WATCH FOR THIS. THEN ON
FRIDAY NIGHT...A SIMILAR PATTERN WILL REPEAT...WITH SOUTH TO
SOUTHWEST GALES EXPECTED OVER THE OPEN WATERS. ANOTHER LOW AND
COLD FRONT WILL CROSS THE LAKE SUNDAY INTO SUNDAY NIGHT. MODERATE
WEST-NORTHWEST WINDS IN ITS WAKE COULD BE STRONGER THAN CURRENTLY
FORECAST IF THE LOW TRENDS STRONGER.

REGARDING THE STORM SYSTEM APPROACHING THE LAKE NEXT
TUESDAY...COMPUTER FORECAST GUIDANCE VARIES ON THE TRACK AND
STRENGTH OF THE LOW PRESSURE. HOWEVER...ALL AGREE THAT THERE WILL
BE A STRONG STORM OVER THE REGION. IT'S TOO EARLY TO BE CONFIDENT
ON WIND DIRECTIONS AND SPEEDS...BUT THE PATTERN WILL BE SUPPORTIVE
OF A PERIOD OR TWO OF AT LEAST GALE FORCE WINDS.
