AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
131 PM CST MON FEB 1 2016

.UPDATE...
1107 AM CST

AN AREA OF DENSE FOG THAT DEVELOPED ACROSS EASTERN IOWA IN THE
PRE-DAWN HOURS EXPANDED EAST THIS MORNING TO THE I-39 CORRIDOR.
IT IS CHALLENGING TO SAY JUST HOW FAR EAST THIS WILL CONTINUE TO
PUSH SINCE LOCATIONS EAST HAVE WARMED SOME AND ALLOWED FOR A
LITTLE MIXING...WITH THE ACTUAL ADVECTION OF THE FOG HAVING SLOWED
ON LIGHT NORTHWEST WINDS. STILL THOUGH A DENSE FOG ADVISORY VERY
WELL COULD BE NEEDED FOR THIS AFTERNOON AS WEB CAMS AND
OBSERVATIONS CONTINUE TO TREND DOWNWARD OVER THE PAST HOUR.

LOOKING AHEAD TO THE STORM SYSTEM CENTERED ON TUESDAY...THE SAME
CONCERNS REMAIN...THOUGH IT IS LOOKING MORE AND MORE LIKE ONLY A
SMALL PART OF THE CWA MAY HAVE WINTRY PRECIPITATION /OR JUST
PRECIPITATION IN GENERAL/ PRIOR TO 9-10 AM TUESDAY MORNING...AND
THAT LOOKS TO BE THE FAR NORTH. THIS IS SIMPLY DUE TO THE FORCING
BEING TIED TO MESOSCALE FRONTOGENESIS...WITH THE DEEP LIFT AND
MOIST ADVECTION NOT ARRIVING UNTIL LATE MORNING. THIS WOULD LIMIT
THE COVERAGE OF SNOW AND/OR FREEZING RAIN. STILL WILL NEED TO
ASSESS SOME OF THE THERMAL PROFILES MORE IN-DEPTH...AS WELL AS
ONSET WHICH STILL COULD BE AS EARLY AS JUST AFTER MIDNIGHT
TONIGHT. GIVEN COOLER HIGH TEMPERATURES IN SOME AREAS DUE TO
FOG/STRATUS TODAY...THAT COULD HELP ANY WINTERY PRECIP ACCUMULATE.
BUT AT THIS TIME IT SEEMS THAT IF AN ADVISORY OR SPS IS NEEDED
FOR LATE TONIGHT AND TUESDAY MORNING IT WOULD ONLY BE FOR OUR FAR
NORTHERN TIER OF COUNTIES NEAR THE WI STATE LINE.

THE SYSTEM OF INTEREST IS NEARING THE FOUR CORNERS REGION ON
WATER VAPOR THIS MORNING. RAOBS FROM THAT REGION INDICATED A 145
KT UPPER JET...ABOUT 15KT HIGHER THAN THE 01.12Z NAM OR GFS
ANALYZED WITH A FEW OTHER MASS PARAMETERS SLIGHTLY UNDERDONE.
THATS NOT SURPRISING WITH SUCH A DEEP PV ANOMALY...HOWEVER IT IS
DIFFICULT TO SAY EXACTLY HOW THAT WILL TRANSLATE DOWNSTREAM OTHER
THAN IT WILL MEAN SOME PROBABLE FLUCTUATIONS IN GUIDANCE. THE 12Z
GFS HAS TRENDED A TAD FURTHER NORTH FOR ITS TUESDAY TRACK...WITH
THE LOW CENTER MOVING JUST NORTH OF THE CWA. STILL PREFER A MORE
MEAN SOLUTION CLOSER TO THE EC...GIVEN THE DEGREE OF CONVECTION
EXPECTED IN THE WARM SECTOR UP INTO ILLINOIS AND INDIANA POSSIBLY
DICTATING THE LOW PATH SOME. STILL LOOKS LIKE NEAR OR SURFACE
BASED CONVECTION COULD REACH UP TO THE I-74 CORRIDOR IF NOT A
LITTLE FURTHER NORTH TUESDAY AFTERNOON...AND WILL NEED TO ASSESS
THAT FURTHER AS WELL.

MTF

&&

.SHORT TERM...
324 AM CST

THROUGH TUESDAY NIGHT...

MAIN FORECAST CHALLENGE REVOLVES AROUND THE DETAILS OF A STRONG
SOUTHWEST LOW EXPECTED TO IMPACT THE REGION TUESDAY.

RIDGE AXIS STRETCHES FROM THE DAKOTAS INTO DOWNSTATE ILLINOIS
EARLY THIS MORNING AND WILL SPREAD EAST THROUGH THE DAY WITH
QUIET WEATHER CONDITIONS EXPECTED ACROSS NORTHERN ILLINOIS AND
NORTHWEST INDIANA AT LEAST INTO THE EVENING. EXPECT HIGH
TEMPERATURES TODAY INTO THE LOW TO MID 40S FOR MOST OF THE CWA
WITH THE NORTHERN TIER OF COUNTIES POSSIBLY HOLDING IN THE UPPER
30S.

MEANWHILE...WATER VAPOR IMAGERY SHOWS AN UPPER LOW DIGGING INTO
THE DESERT SOUTHWEST EARLY THIS MORNING AND IS EXPECTED TO MOVE
ACROSS THE PLAINS THIS EVENING AND TONIGHT WITH SURFACE
CYCLOGENESIS OCCURRING OVER KANSAS TONIGHT. 00Z NAM AND GFS
MODELS BOTH SHOW FGEN BAND DEVELOPING ACROSS FAR NORTHERN ILLINOIS
AFTER MIDNIGHT TONIGHT WHICH WOULD APPEAR TO BE THE BEST CHANCE
FOR ANYWHERE IN THE FORECAST AREA TO SEE ACCUMULATING SNOWFALL AS
WE ARE STILL ON THE COLD SIDE OF THE BAROCLINIC ZONE AT THAT TIME.
LAPSE RATES ABOVE 600MB ARE STEEP WHICH WILL HELP THE POTENTIAL TO
SEE MESOSCALE BANDING WITH A QUICK 1-3 INCHES OF SNOW POSSIBLE.
THAT SAID...THERE ARE SOME UNCERTAINTIES AND LIMITING FACTORS. THE
06Z NAM HAS SHIFTED MUCH FARTHER NORTH WITH THE LEAD WAVE FOR ANY
PRECIP OVERNIGHT. FORECAST SOUNDINGS ALSO SHOW A DRY LAYER UP TO
AROUND 700MB THROUGH LATE THIS EVENING WHICH WOULD HAVE TO BE
OVERCOME TO SEE ANY SNOW ACCUMULATIONS. CONFIDENCE IN THE
MESOSCALE DETAILS AT THIS POINT IS ONLY LOW TO MEDIUM BUT PLAN ON
MAINTAINING A FORECAST OF AROUND 1-3 INCHES NORTH OF A BYRON TO
WAUKEGAN LINE...WITH SOME POSSIBILITY FOR HIGHER AMOUNTS IF
INGREDIENTS COME TOGETHER.

OTHERWISE...RAPID WARMING IN THE COLUMN IS EXPECTED TO OCCUR WITH
NEARLY 60KT SOUTH TO SOUTHWEST WINDS AT 800MB. NAM SOUNDINGS FOR
RFD SUPPORT SNOW THROUGH ROUGHLY 15Z BUT BY 16/17Z THE WARM NOSE
IS GOING TO BE TOO WARM FOR ANY REFREEZING AND EXPECT PLAIN RAIN
THEREAFTER. COULD BE A BRIEF WINDOW WHERE WE SEE SLEET MIXED IN
HOWEVER GENERALLY EXPECT THE TRANSITION TO RAIN TO BE FAST WHICH
WILL MITIGATE IMPACTS FROM FREEZING/MIXED PRECIP.

FARTHER SOUTH AND SOUTHEAST IN THE WARM SECTOR...GUIDANCE
CONTINUES TO SHOW A CORRIDOR OF INSTABILITY...INCLUDING SOME
SURFACE BASED OR NEAR SURFACE BASED INSTABILITY SOUTH OF THE I-80
CORRIDOR WHICH WILL RESULT IN A THREAT FOR THUNDERSTORMS. SPC
BRINGS THE DAY 2 MARGINAL RISK LINE RIGHT UP TO THE SOUTHERN CWA
BOUNDARY WHICH IS REASONABLE. ITS PROBABLY SPLITTING HAIRS AT THIS
POINT BUT WE WILL PROBABLY HAVE TO KEEP AN EYE ON CONVECTIVE
ACTIVITY IN OUR FAR SOUTHERN COUNTIES FOR SOME THREAT OF SEVERE
WEATHER IN THE HIGH SHEAR/LOW CAPE ENVIRONMENT.

LATE TUESDAY EVENING...LOW PRESSURE WILL LIFT ACROSS LAKE
MICHIGAN INTO LOWER MICHIGAN WITH COLDER AIR STARTING TO WRAP
ACROSS NORTHERN ILLINOIS. WHILE TEMPERATURES ALOFT COOL ENOUGH TO
SUPPORT SNOW...WE MIGHT JUST END UP WITH SOME DRIZZLE AS THE DRY
SLOT SPREADS OVERHEAD RESULTING IN A LOSS OF ICE CRYSTALS IN THE
COLUMN.

BMD

&&

.LONG TERM...
324 AM CST

WEDNESDAY THROUGH MONDAY...

COLDER BUT SEASONABLE TEMPERATURES EXPECTED THE SECOND HALF OF
THE WEEK INTO THE WEEKEND AS THE EASTERN HALF OF THE COUNTRY STAYS
UNDER A GENERALLY TROUGHY UPPER LEVEL PATTERN. SURFACE HIGH
PRESSURE WILL BUILD FROM THE PLAINS INTO THE LOWER/MID MISSISSIPPI
VALLEY WEDNESDAY THROUGH FRIDAY AND SHOULD GIVE THE LOCAL AREA
GENERALLY DRY WEATHER THOUGH MODELS STILL SHOW A GLANCING SHOT OF
WINTRY WEATHER BY A CLIPPER SYSTEM THURSDAY NIGHT INTO EARLY
FRIDAY AND AGAIN FRIDAY NIGHT INTO SATURDAY. CHANCES WILL BE
BETTER TO OUR NORTH HOWEVER SO NOTHING MORE THAN SLIGHT CHANCE
POPS FOR NOW. BOTH THE ECMWF AND GFS BRING A BRIEF WARMUP OVER THE
WEEKEND AS A TRANSIENT MID/UPPER LEVEL RIDGE TRANSLATES ACROSS THE
REGION...BUT BOTH MODELS ALSO SHOW ANOTHER SHOT OF ARCTIC AIR
SPILLING INTO THE REGION AS WE HEAD INTO NEXT WEEK...SO THE WARMUP
MAY BE SHORT LIVED.

.AVIATION...

1142 AM...A LARGE AREA OF LOW CLOUDS AND FOG HAS SLOWLY BEEN
PUSHING EAST ACROSS NORTH CENTRAL IL THIS MORNING...CURRENTLY JUST
WEST OF DKB. CONFIDENCE IS FAIRLY LOW REGARDING HOW FAST AND HOW
FAR TO THE EAST THIS WILL EXTEND THIS AFTERNOON. SOME GUIDANCE
SHOWS IT EXTENDING INTO THE CHICAGO AREA TERMINALS AFTER SUNSET
AND NOT QUITE AS LOW AS. GIVEN THE UNCERTAINTY INCLUDED A TEMPO AT
DPA TOWARD SUNSET AND JUST SCATTERED MENTION AT ORD/MDW/GYY AND
WILL NEED TO MONITOR TRENDS THIS AFTERNOON. RFD SHOULD REMAIN
SOCKED IN INTO THIS EVENING WITH PERHAPS SOME SLOW IMPROVEMENT
LATER THIS EVENING AND OVERNIGHT AS EASTERLY WINDS INCREASE AND
DRIER AIR ADVECTS INTO THE AREA.

LIGHT WINDS WILL BECOME LIGHT NORTHEAST LATER THIS AFTERNOON AND
THEN BECOME EASTERLY THIS EVENING. THE GRADIENT WILL TIGHTEN
OVERNIGHT INTO TUESDAY MORNING AS LOW PRESSURE APPROACHES THE
WESTERN GREAT LAKES TUESDAY AFTERNOON. EASTERLY WINDS WILL
STEADILY INCREASE TOWARD SUNRISE TUESDAY WITH A PERIOD OF VERY
STRONG EASTERLY WINDS EXPECTED FROM MID MORNING THRU MID
AFTERNOON. GUSTS 30-35KTS WILL BE POSSIBLE. WINDS WILL BEGIN TO
DIMINISH BY LATE TUESDAY AFTERNOON AND BECOME SOUTHEASTERLY.

A PERIOD OF LIGHT SNOW IS POSSIBLE LATE TONIGHT TOWARD SUNRISE
ACROSS NORTHERN IL. THERE REMAINS SOME UNCERTAINTY REGARDING THE
DURATION AND LOCATION OF THIS PRECIP. IT APPEARS IT MAY DEVELOP
JUST NORTH OF THE CHICAGO AREA TERMINALS AND THEN PUSH INTO
SOUTHERN WI. MAINTAINED PROB MENTION AT RFD BUT TRENDS WILL NEED
TO BE MONITORED OVERNIGHT FOR POSSIBLE MENTION IN DPA/ORD. A
BRIEF LULL IN PRECIP IS EXPECTED MID TUESDAY MORNING WITH AN AREA
OF RAIN THEN SPREADING ACROSS THE TERMINALS FROM LATE MORNING
THRU MID/LATE AFTERNOON. AS THE LOW LEVELS SATURATE AND THE LOW
APPROACHES...CIGS WILL LIKELY LOWER TO IFR/LIFR AND ITS POSSIBLE
THERE COULD BE A PERIOD OF 1-2SM VIS. INSTABILITY ALOFT WOULD ALSO
SUPPORT THE POTENTIAL FOR ISOLATED THUNDERSTORMS BUT NO MENTION
BASED ON CURRENT LOW CONFIDENCE REGARDING TIMING/DURATION. CMS

&&

.MARINE...

131 PM...LARGE WEAK HIGH PRESSURE EXTENDING FROM THE NORTHERN
PLAINS TO THE SOUTHERN GREAT LAKES REGION WILL MOVE NORTHEAST INTO
ONTARIO AND QUEBEC TUESDAY AS IT SLOWLY STRENGTHENS. LOW PRESSURE
OVER COLORADO WILL MOVE NORTHEAST TUESDAY CROSSING CENTRAL LAKE
MICHIGAN TUESDAY NIGHT INTO WEDNESDAY MORNING. THE GRADIENT IS
EXPECTED TO TIGHTEN TUESDAY MORNING WITH EASTERLY GALES DEVELOPING
OVER THE SOUTHERN PART OF THE LAKE TUESDAY MORNING AND THEN ACROSS
THE NORTHERN PART OF THE LAKE TUESDAY AFTERNOON. THE CURRENT GALE
WATCH TIMING LOOKS REASONABLE AND PLAN TO UPGRADE THE GALE WATCH
TO A GALE WARNING THIS AFTERNOON. AS THE LOW LIFTS NORTHEAST INTO
SOUTHWEST QUEBEC WEDNESDAY...COLD AIR ALONG WITH A TIGHT PRESSURE
GRADIENT WILL ALLOW NORTHWESTERLY WINDS TO INCREASE TO 30 KTS WITH
SOME POTENTIAL FOR LOW END GALES ESPECIALLY OVER NORTHERN PORTIONS
OF THE LAKE. WINDS WILL DIMINISH THURSDAY AND REMAIN WESTERLY
UNTIL ANOTHER LOW MOVES ACROSS ONTARIO FRIDAY NIGHT. WINDS WILL
TURN MORE SOUTHWESTERLY AND INCREASE AHEAD OF THIS LOW FRIDAY
NIGHT. CMS
