AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE, IL
220 PM CDT FRI APR 1 2016

.SHORT TERM...
153 PM CDT

THROUGH TONIGHT...

A COLD FRONT SERVING AS A MORE ENHANCED FOCUS FOR SHOWERS IS
PUSHING INTO NORTHWEST ILLINOIS EARLY THIS AFTERNOON. THIS IS
UNDER AN IMPRESSIVE THERMAL TROUGH...AROUND -31C AT 500MB...WHICH
IS IN THE LOWEST TWO PERCENTILE FOR EARLY APRIL IN LOCAL RAOB
CLIMATOLOGY. SURFACE READINGS IN THE UPPER 40S ACROSS NORTH
CENTRAL ILLINOIS HAVE REACHED THEIR CONVECTIVE VALUES...AND
VISIBLE SATELLITE IMAGERY ALSO INDICATES ENHANCEMENT AHEAD OF THE
FRONT. SO SHOWERS SHOULD INCREASE IN A NORTHEAST-TO-SOUTHWEST
CORRIDOR AHEAD OF THE FRONT AND TRAVERSE THE AREA THROUGH THE REST
OF THE AFTERNOON...WITH CHICAGO MOST FAVORED TO SEE THESE SHOWERS
BETWEEN 4 PM AND 7 PM. WET BULB ZERO HEIGHTS REMAIN AROUND 2500
FT ON RAP AND AIRCRAFT SOUNDINGS...SO WONT TAKE MUCH TO GET SOME
SMALL HAIL (ALREADY HAD A REPORT OF SUCH EARLIER FROM BENTON
COUNTY). ALSO THERE REMAINS THE POSSIBILITY OF A COUPLE
THUNDERSTORMS WITHIN THIS AXIS OF SHOWERS.

CLOUDS SHOULD CLEAR FROM WEST TO EAST DURING THE EVENING AS DRIER
AIR MOVES IN BEHIND THE FRONT. LOWS AT OR SLIGHTLY BELOW FREEZING
ARE FORECAST.

MTF

&&

.LONG TERM...
220 PM CDT

SUNDAY NIGHT THROUGH FRIDAY...

THE MAIN FORECAST CONCERNS DURING THE PERIOD WILL BE WITH THE STRONG
NORTHWEST WINDS AND COLD TEMPERATURES FOR SATURDAY...ALONG WITH THE
POTENTIAL OF SOME SNOW SHOWERS. WE HAVE ISSUED A WIND ADVISORY FROM
15UTC SATURDAY THROUGH 00 UTC SUNDAY FOR THE STRONG WINDS.

A VERY POTENT CLIPPER SYSTEM...BEING DRIVEN BY A 130+ KT UPPER LEVEL
JET...WILL RAPIDLY DIG SOUTH-SOUTHEASTWARD OVER THE WESTERN GREAT
LAKES ON SATURDAY. THE TRACK OF THE SURFACE LOW IS STILL EXPECTED TO
PASS TO OUR NORTHEAST OVER WESTERN LOWER MICHIGAN...WHICH SHOULD
ALSO RESULT IN THE HEAVIER SNOW SHOWERS REMAINING NORTHEAST OF THE
AREA. HOWEVER...SOME LOW CONVECTIVE RAIN SHOWERS...MIXING WITH OR
EVENING CHANGING TO SOME SNOW SHOWERS IS STILL POSSIBLY OVER
NORTHEASTERN ILLINOIS...AND POSSIBLY INTO PORTIONS OF NORTHWESTERN
INDIANA AS WELL SATURDAY MORNING AND INTO THE EARLY AFTERNOON. MODEL
SOUNDINGS INDICATE VERY STEEP LOWER LEVEL LAPSE RATES DEVELOPING AS
THE SYSTEMS COLD FRONT MOVES INTO THE AREA. THIS COULD SUPPORT SOME
VERY BRIEF BURSTS OF SNOW AND GRAUPEL...BUT ANY ACCUMULATIONS WOULD
LIKELY REMAIN LIGHT AND CONFINED TO GRASSY AREAS.

OF MORE CONCERN WITH THIS CLIPPER SYSTEM WILL BE THE STRONG
NORTHWEST WINDS AND SHARPLY COLDER TEMPERATURES. THE TRACK OF THE
CLIPPER WILL BE VERY FAVORABLE FOR PRODUCING STRONG GUSTY WINDS OF
45 TO 50 MPH AS THE COLD FRONT PUSHES ACROSS THE AREA BY MIDDAY
SATURDAY. I WOULD ALSO NOT BE SURPRISED TO SEE A VERY SHORT PERIOD
OF SLIGHTLY HIGH WIND GUSTS UP CLOSER TO 55 MPH RIGHT AS THE FRONT
MOVES THROUGH AND STRONG PRESSURE RISES AROUND 10 MB/6HR OVERSPREAD
THE AREA AROUND MIDDAY/EARLY AFTERNOON. THESE STRONG WINDS IN
COMBINATION WITH DROPPING TEMPERATURES INTO THE UPPER 30S WILL ALSO
CREATE UNSEASONABLE COLD WIND CHILLS INTO THE MID TO UPPER 20S. A
WIND ADVISORY HAS BEEN ISSUED TO COVER THE PERIOD OF STRONGEST WINDS
LATE SATURDAY MORNING THROUGH EARLY EVENING.

CLIPPER SYSTEM NUMBER TWO QUICKLY MOVES OVER THE UPPER MIDWEST AND
INTO SOUTHERN WISCONSIN BY SUNDAY. THIS TRACK STILL LOOKS TO PUT THE
AREA IN THE WARM SECTOR OF THE SYSTEM. SO SUNDAY WILL ALSO BE
BREEZY...THOUGH NOT TO THE EXTENT OF SATURDAYS WINDS. THE BIG
DIFFERENCE ON SUNDAY WILL BE THE MUCH WARMER CONDITIONS...WITH
TEMPERATURES LIKELY TO TOP OUT IN THE MID TO UPPER 50S EAST...TO THE
LOW 60S WEST. IT DOES APPEAR THAT A VERY SHARP TEMPERATURE GRADIENT
WILL SET UP OVER FAR NORTHERN ILLINOIS AND SOUTHERN WISCONSIN...SO
YOU WILL NOT HAVE TO GO TO FAR NORTH INTO WISCONSIN TO GET NORTH OF
THE WARM FRONT AND INTO THE COLDER AIR MASS. THIS COLDER AIR MASS
WILL RETURN TO THE AREA FOR MONDAY AS THE CLIPPER SYSTEM PUSHES A
COLD FRONT SOUTHWARD OVER THE AREA SUNDAY NIGHT. THERE COULD BE A
FEW SHOWERS AS THIS FRONT MOVES THROUGH...BUT THE MAIN STORY WILL BE
THE RETURN OF COLDER TEMPERATURES FOR MONDAY.

FOLLOWING THE PASSAGE OF A STOUT 1030+ MB SURFACE HIGH MONDAY
NIGHT...YET ANOTHER CLIPPER SYSTEM LOOKS TO SHIFT OVER THE UPPER
MIDWEST BY LATE TUESDAY. THIS SYSTEM WILL ULTIMATELY BRING US A DAY
OF SOME WARMER TEMPERATURES FOR WEDNESDAY. HOWEVER...THERE WILL ALSO
BE INCREASING CHANCES OF PRECIPITATION TUESDAY NIGHT AND WEDNESDAY.
THIS PRECIPITATION COULD EVEN ONSET AS A RAIN OR SNOW/SLEET MIX OVER
NORTHEASTERN SECTIONS OF THE AREA TUESDAY EVENING BEFORE THE WARMER
AIR BEGINS TO CHANGE EVERYTHING OVER TO RAIN BY DAYBREAK WEDNESDAY.
HOWEVER...CONFIDENCE ON THIS MIX AT THIS RANGE IS STILL LOW.

FINALLY...AS THE CLIPPER SYSTEM SHIFTS EASTWARD OVER THE UPPER GREAT
LAKES REGION...THERE IS GOOD MODEL/ENSEMBLE CONSENSUS THAT MORE COLD
WILL RETURN TO THE AREA LATER IN THE WEEK...WITH SOME POSSIBLE RAIN
AND SNOW SHOWERS.

KJB

&&

.AVIATION...
FOR THE 18Z TAFS...

THE PRIMARY CONCERNS WITH THE CHICAGO AREA TAF SITES ARE:

- SHRA INCREASING IN COVERAGE THIS AFTERNOON WITH A SLIGHT CHANCE
  FOR TSRA AND BRIEF SMALL HAIL.
- WEST-NORTHWEST WINDS GUSTING TO OR OVER 40 KT LATE MORNING AND
  AFTERNOON SATURDAY.

THE ATMOSPHERE IS FAVORABLE FOR SHOWERS TO RE-INCREASE IN COVERAGE
THIS AFTERNOON ACROSS NORTHERN ILLINOIS AND NORTHWEST INDIANA.
THERE SHOULD BE A BROAD AXIS OF GREATER SHOWER COVERAGE THAT
DEVELOPS ACROSS NORTH CENTRAL ILLINOIS BY 20Z THAT SHIFTS OVER THE
CHICAGO AREA WITHIN 21Z-01Z. IT IS WITHIN THIS AREA THAT THERE
PROBABLY WILL BE ISOLATED DEEPER SHOWERS AND THE POTENTIAL FOR
WIDELY ISOLATED THUNDER. WEST WINDS WILL INCREASE IN SPEED THIS
AFTERNOON AND TURN NORTHWEST BEHIND A COLD FRONT BY EARLY EVENING.

ANOTHER QUICK MOVING CLIPPER SYSTEM WILL TRAVERSE THE AREA ON
SATURDAY MORNING LEADING TO A SHARP INCREASE IN WIND SPEEDS BY MID
MORNING. AS THE WINDS TURN NORTHWEST BY LATE MORNING THE GUSTS ARE
FAVORED TO REACH OR EVEN SLIGHTLY EXCEED 40 KT.

MTF

&&

.MARINE...
328 AM CDT

MAIN MARINE CONCERNS CONTINUE TO BE ON THE POTENTIAL FOR GALES
QUICKLY DEVELOPING LATE SATURDAY MORNING ALONG THE SOUTH HALF OF
THE LAKE THEN EXPANDING NORTH AND LINGERING THROUGH THE EVENING
HOURS.

FOR TODAY WINDS WILL BE GENERALLY FROM THE NORTH SHIFTING TO
NORTHWEST AND INCREASING TO 15 TO 25 KT...THEN ANOTHER AREA OF LOW
PRESSURE WILL DROP SOUTHEAST ACROSS THE UPPER MIDWEST TOWARDS THE
WESTERN GREAT LAKES AFTER MIDNIGHT REACHING NORTHERN LAKE MICHIGAN
SHORTLY AFTER DAYBREAK SATURDAY. THIS WILL CAUSE WINDS AHEAD OF
THIS LOW TO SHIFT TO THE SOUTHWEST LATE TONIGHT INTO EARLY
SATURDAY...WITH A RAPIDLY TIGHTENING PRESSURE GRADIENT. THIS WILL
LIKELY RESULT IN GALES QUICKLY DEVELOPING ALONG THE SOUTHERN HALF
OF THE LAKE FIRST SATURDAY MORNING...THEN EXPANDING NORTH TO COVER
THE NORTHERN HALF OF THE LAKE BY EARLY SATURDAY AFTERNOON. GALES
TO 45 KT FOR THE SOUTH HALF LOOK FAVORABLE...AND TO 40 KT FOR THE
NORTH HALF. THE LOW PRESSURE WILL QUICKLY SHIFT EAST BY SATURDAY
EVENING...WITH WINDS RELAXING AND BECOMING WEST BY EARLY SUNDAY
MORNING. THEN YET ANOTHER LOW PRESSURE SYSTEM WILL APPROACH LAKE
MICHIGAN SUNDAY AFTERNOON...HOWEVER WINDS DO NOT LOOK AS STRONG
WITH THE SYSTEM SUNDAY.
