AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
408 AM CDT SUN APR 14 2013

.DISCUSSION...
343 AM CDT

THE MAIN WEATHER CONCERNS WILL CONTINUE TO FOCUS ON WINDS
TODAY...ALONG WITH TEMPERATURES AND PRECIPITATION CHANCES OVER THE
NEXT SEVERAL DAYS.

I HAVE ISSUED A WIND ADVISORY FOR MY SOUTHWEST COUNTIES FOR THIS
AFTERNOON AND EARLY THIS EVENING.

THE WEATHER CONCERNS TODAY AND INTO MONDAY WILL BE WITH REGARDS TO A
SIGNIFICANT WEATHER DISTURBANCE...CURRENTLY DIGGING ACROSS THE
NORTHERN ROCKIES OF MONTANA AND WYOMING...PER THE LATEST WATER VAPOR
IMAGERY. THIS SYSTEM IS INDUCING LARGE SURFACE PRESSURE FALLS ACROSS
THE PLAINS STATES EARLY THIS MORNING...ALLOWING A COLORADO LOW TO
ORGANIZE AND MOVE OUT ACROSS THE PLAINS. STRONG SOUTHERLY
TRAJECTORIES ARE SETTING UP TO THE EAST OF THIS LOW ACROSS MUCH OF
THE CENTRAL CONUS. IN FACT...PROFILER AND VWP OBS ACROSS THE CENTRAL
STATES INDICATE THAT A VERY IMPRESSIVE LOW LEVEL JET IN EXCESS OF 50
KT HAS DEVELOPED ACROSS THE PLAINS THIS MORNING. THIS IS SETTING UP
SOME DECENT ISENTROPIC UPGLIDE AND MOISTURE TRANSPORT...WHICH HAS
ALLOWED SHOWERS AND EVEN A FEW THUNDERSTORMS TO DEVELOP ACROSS MUCH
OF IOWA SOUTHEASTWARD ACROSS CENTRAL SECTIONS OF ILLINOIS EARLY THIS
MORNING.

THIS ACTIVITY WILL CONTINUE TO SHIFT ACROSS NORTHERN ILLINOIS
THROUGH THE EARLY TO MID MORNING TODAY AS A SURFACE WARM FRONT
RACES NORTHWARD. TEMPERATURES ACROSS FAR NORTHERN ILLINOIS ARE
GENERALLY IN THE LOW TO MID 30S EARLY THIS MORNING...WITH
SUBFREEZING DEW POINTS IN PLACE. AN AMDAR SOUNDING OUT OF ORD
AROUND 430 UTC INDICATED A THERMODYNAMIC PROFILE SUPPORTIVE OF A
WINTERY MIX. THEREFORE...IT STILL APPEARS THAT THERE COULD BE A
SHORT WINDOW EARLY THIS MORNING IN WHICH THE PRECIPITATION COULD
START AS A SNOW AND SLEET MIX. HOWEVER...THIS WOULD BE VERY SHORT
LIVED AS THE STRONG WARM AIR ADVECTION WILL QUICKLY TAKE CONTROL
AND WARM PROFILES WELL ABOVE FREEZING VERY QUICKLY.

THE SURFACE WARM FRONT SHOULD SLOWLY LIFT ACROSS FAR NORTHERN
ILLINOIS TODAY. ONCE THIS FRONT PASSES...WINDS WILL INCREASE
SUBSTANTIALLY OUT OF THE SOUTH TODAY. VERY STRONG PRESSURE RISES ARE
EXPECTED TO ENGULF THE UPPER MIDWEST THOUGH THE DAY AS THE SURFACE
LOW QUICKLY MOVES NORTHEASTERLY TOWARDS SOUTHERN MINNESOTA. WITH
THIS IN MIND IT APPEARS WINDS OF 20 TO 30 MPH WITH GUSTS UP TO 40
MPH ARE LIKELY TODAY. HOWEVER...EVEN STRONGER WINDS ARE POSSIBLE
ACROSS CENTRAL ILLINOIS. BECAUSE OF THIS I HAVE OPTED TO GO WITH A
WIND ADVISORY FOR MY FAR SOUTHWEST COUNTIES...WHERE WINDS GUSTS
COULD HIT 45 MPH TODAY. THESE STRONG WINDS MAY BE SLOW TO SUBSIDE
THIS EVENING...AS THE AREA REMAINS IN THE WARM SECTOR OF THE SYSTEM.

TEMPERATURES TODAY WILL LIKELY HIT OR EXCEED 70 IN MOST AREAS. THE
ONLY EXCEPTION TO THIS WARMTH WILL BE ACROSS FAR NORTHEASTERN
ILLINOIS...LIKELY NORTH OF CHICAGO INTO LAKE COUNTY ILLINOIS. THE
SURFACE WARM FRONT MAY BE SLOW TO CLEAR FAR NORTHERN ILLINOIS SUNDAY
AFTERNOON...AND THIS COULD RESULT IN LOW LEVEL TRAJECTORIES MORE
SOUTHEASTERLY OFF OF LAKE MICHIGAN...THUS RESULTING IN COOLER
CONDITIONS THERE NEAR THE LAKE IN THE AFTERNOON. HOWEVER...IT
APPEARS THAT DURING THE EVENING THE FLOW MAY BECOME
SOUTH-SOUTHWESTERLY EVENING IN FAR NORTHEASTERN ILLINOIS. THIS COULD
RESULT IN THE DAYTIME HIGH TEMPERATURES DURING THE EVENING IN PLACES
IN AND AROUND WAUKEGAN.

A SURFACE COLD FRONT WILL IS EXPECTED TO BEGIN MOVING ACROSS THE
AREA VERY LATE TONIGHT AND INTO MONDAY. THIS FRONT WILL BRING
ANOTHER CHANCE OF SHOWERS AND THUNDERSTORMS TO THE
REGION...ESPECIALLY LATE SUNDAY NIGHT AND INTO MONDAY.

THINGS STILL LOOK COMPLEX INTO THE MIDDLE OF THE WEEK. GUIDANCE
CONTINUES TO STRUGGLE WITH THE PLACEMENT OF THE SURFACE FRONT.
HOWEVER...THEY DO SUGGEST A BIT FARTHER SOUTH POSITION OF THE
FRONT THEN PREVIOUSLY FORECAST. THE PRESENCE OF THIS FRONT AND UPPER
LEVEL SOUTHWESTERLY PATTERN WILL LIKELY CONTINUE A FAIRLY ACTIVE
WEATHER PATTERN WITH SEVERAL WAVES OF SHOWERS AND THUNDERSTORMS
POSSIBLE MONDAY AND TUESDAY...ESPECIALLY ACROSS THE SOUTHERN HALF OF
MY AREA...WHERE A SOUTHERLY LOW LEVEL JET LOOKS TO CONTINUE TO
NOSE UP INTO THE AREA...PROVIDING AMPLE MOISTURE TRANSPORT AND
ISENTROPIC ASCENT OVER THE SURFACE FRONTAL BOUNDARY.

LATER IN THE PERIOD...WEDNESDAY INTO WEDNESDAY NIGHT IT STILL
APPEARS THE WESTERN CONUS TROUGH WILL KICK OUT ACROSS THE
PLAINS...LIKELY SUPPORTING ANOTHER SIGNIFICANT STORM SYSTEM ACROSS
THE CENTRAL CONUS. THERE STILL REMAINS A LARGE AMOUNT OF SPREAD IN
TERMS OF THE EXACT TRACK AND TIMING OF THIS SYSTEM ACROSS THE
CENTRAL PORTION OF THE COUNTRY. HOWEVER...GIVEN THE EXPECTATION FOR
DECENT MID LEVEL RIDGING ACROSS THE SOUTHEASTERN CONUS...ASSOCIATED
WITH A NEGATIVE PNA...IT WOULD SEEM THAT A NORTHEASTERLY TRACK OF
THE SURFACE LOW SOMEWHERE ACROSS MISSOURI AND ILLINOIS WOULD STILL
BE FAVORED. THE MAIN QUESTION STILL IS THE EXACT TIMING. THIS WILL
HAVE LARGE AFFECTS ON TEMPERATURES LATE WEDNESDAY INTO
THURSDAY...ALONG WITH THE POTENTIAL FOR STRONG CONVECTION.

IT ALSO APPEARS THAT CONDITIONS COULD BECOME COLD ENOUGH FOR SOME
RAIN AND SNOW SHOWERS LATE THURSDAY NIGHT AND ON FRIDAY AS THE UPPER
LEVEL SYSTEM MOVES OVERHEAD. OVERALL...TEMPERATURES LOOK TO REMAIN
BELOW NORMAL FOR MUCH OF THE EXTENDED PERIOD.

.AVIATION...

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

* SLIGHT CHC OF LIGHT SHRA JUST BEFORE DAYBREAK THROUGH MID-
  MORNING.

* PSBL LLVL WIND SHEAR AT 2KFT AGL AFT 03Z MON TO 50KT.

BEACHLER

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

HIGH PRESSURE CENTERED OVER THE OHIO VALLEY WILL CONTINUE TO DRIFT
EAST AND WEAKEN...WITH A STRENGTHENING LOW PRESSURE SYSTEM LIFTING
NORTHEAST ACROSS THE CENTRAL PLAINS. EARLY THIS MORNING THE
GRADIENT IS MINIMAL...WHICH HAS ALLOWED WINDS TO BECOME LIGHT AND
VARIABLE. REGIONAL RADAR IMAGERY INDICATES A LEADING EDGE OF SOME
SHOWERS BEGINNING TO DEVELOP ACROSS CENTRAL IOWA STRETCHING
SOUTHEAST THROUGH SOUTHCENTRAL IL...OR ALONG A WARM FRONTAL
BOUNDARY. THIS BOUNDARY WILL STEADILY LIFT NORTH TOWARDS NORTHERN
IL/NORTHWEST IN AIRFIELDS THIS MORNING...BRINGING A SLIGHT CHC FOR
RAIN SHOWERS. A FEW SHOWERS MAY MIX WITH SLEET/SNOW ACROSS FAR
NORTHWEST IL BEFORE 12Z...THEN ALL PRECIP SHUD QUICKLY COME TO AN
END BY 15Z. WHILE VFR CONDS WILL PREVAIL...A FEW POCKETS OF MVFR
CIGS MAY OCCUR WITH THE MORNING PRECIP.

THEN THE FOCUS TURNS TOWARDS A STRONG GRADIENT THAT WILL ALLOW
SOUTHERLY WINDS TO OCCASIONALLY GUST TO 35KT MIDDAY THROUGH
SUNSET. IT IS POSSIBLE THAT A FEW GUSTS COULD TOUCH 40KT...HOWEVER
NOT ANTICIPATING A HIGH FREQUENCY. THEN WINDS DECOUPLE AFT
SUNSET...HOWEVER GUSTY WINDS WILL CONTINUE TO INCREASE ARND 2KFT
AGL TO 55KTS. WHICH INTRODUCES THE POSSIBILITY FOR LLVL WIND
SHEAR. THEN A COLD FRONT WILL PROGRESS EAST TOWARDS THE REGION
EARLY MON MORNING...WITH ANOTHER CHC FOR MVFR CIGS AND PRECIP AFT
06Z MON.

.MARINE...
217 AM CDT

AN AREA OF HIGH PRESSURE CENTERED OVER THE OHIO VALLEY...WITH AN
INFLUENCE ACROSS THE WESTERN GREAT LAKES...WILL SLOWLY WEAKEN AND
DRIFT EAST. IN THE WAKE OF THE DEPARTING RIDGE OF HIGH PRESSURE WILL
BE A STRENGTHENING LOW PRESSURE SYSTEM CENTERED THIS MORNING OVER
THE CENTRAL PLAINS...WITH A FRONTAL BOUNDARY LIFTING NORTH ACROSS
CENTRAL IOWA STRETCHING EAST THROUGH SOUTHCENTRAL IL. AHEAD OF THE
LOW PRESSURE MUCH OF LAKE MICHIGAN WILL OBSERVE LIGHT EASTERLY
WINDS...THEN WITH A TIGHTENING PRESSURE GRADIENT...WINDS WILL
QUICKLY INCREASE SHORTLY AFTER DAYBREAK. GUSTS WILL ALSO
INCREASE...WITH GUIDANCE INDICATING THAT GUSTS COULD APPROACH
30-35KT. THE LARGEST CAVEAT IS THAT IT APPEARS A SHALLOW MARINE
STABLE LAYER WILL DEVELOP...WHICH SHOULD LIMIT HOW MUCH OF THESE
GUSTY WINDS ACTUALLY REACH THE LAKE SURFACE TODAY. THUS AT THIS TIME
HAVE OPTED TO MAINTAIN NO HEADLINES FOR THE OPEN WATERS. FOR THE
NEARSHORE WATERS IT WILL BE A SLIGHTLY DIFFERENT STORY. FLOW WILL
TURN SOUTHERLY ACROSS THE SOUTHERN PORTIONS OF THE LAKE TODAY...WITH
AGAIN A STABLE MARINE LAYER. ALTHOUGH IT DOES APPEAR FAVORABLE THAT
ENOUGH GUSTY WINDS COULD BLEED OVER INTO THE NEARSHORE WATERS FROM
NORTHWEST IN...PRODUCING FAVORABLE CONDITIONS FOR SMALL CRAFT WINDS.
IT IS CONCEIVABLE THAT A FEW GALE FORCE GUSTS TO 35 KT MAY OCCUR IN
THE NEARSHORE WATERS...MAINLY FOR THE INDIANA PORTION OF THE
NEARSHORE.

IN ADDITION THE GUSTY WINDS...THE FRONTAL BOUNDARY THAT WILL LIFT
NORTH ACROSS THE SOUTHERN PORTION OF THE LAKE THIS MORNING MAY
PRODUCE A FEW LIGHT RAIN SHOWERS BEFORE MID-MORNING FOR THE FAR
SOUTHERN PORTIONS OF THE LAKE. THEN LATER IN THE DAY THIS BOUNDARY
WILL LIFT NORTH ACROSS THE REMAINDER OF THE LAKE...WITH CONTINUED
CHANCES FOR RAIN AND POSSIBLY MIXED WITH SNOW FOR THE NORTHERN
PORTIONS OF THE LAKE.

LOW PRESSURE WILL REACH NORTHEAST WISCONSIN LATE TONIGHT/EARLY
MONDAY...WITH THE GRADIENT DIMINISHING OVER THE LAKE. THIS WILL
ALLOW WINDS TO RELAX OVERNIGHT/EARLY MONDAY TO LESS THAN 30 KT. THEN
WINDS TURN NORTHWEST/NORTH MONDAY NIGHT THROUGH TUE. HIGH PRESSURE
ACROSS CENTRAL CANADA WILL BEGIN TO SLIDE SOUTHEAST ACROSS THE UPPER
MIDWEST/NORTHERN LAKES...WITH WINDS TURNING NORTHEAST. THEN YET
ANOTHER POTENT LOW PRESSURE SYSTEM IS POISED TO DEVELOP MID-WEEK
ACROSS THE CENTRAL PLAINS. THIS NEXT SYSTEM COULD BRING A RETURN OF
NEAR GALE FORCE CONDITIONS WED NGT/EARLY THUR TO LAKE MICHIGAN.
