AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
301 AM CST SUN FEB 13 2011

.DISCUSSION...
325 CST

INITIAL FORECAST CONCERNS ARE WITH PRECIP POTENTIAL...MINIMAL IT
APPEARS...WITH CLIPPER SYSTEM DROPPING SOUTHEAST ACROSS THE UPPER
MIDWEST THIS AFTERNOON AND EVENING. FOCUS THEN SHIFTS TO
TEMPERATURES WITH MUCH ANTICIPATED THAW NEXT WEEK.

SATELLITE VAPOR IMAGERY DEPICTS SHORT WAVE CLIPPER SYSTEM
PROPAGATING SOUTHEAST ACROSS THE UPPER MIDWEST. AS NOTED IN EARLIER
UPDATE...SOUNDINGS INDICATED DRY LOW/MID LEVELS UPSTREAM ACROSS THE
MIDWEST WHICH HAS RESULTED IN MAINLY JUST INCREASING MID CLOUD
SHIELD ACROSS IA/IL WHILE PRECIP HAS BEEN LIMITED TO MN/WI. MODEL
FORECAST SOUNDINGS CONTINUE TO SUGGEST THAT PRECIP THREAT WILL BE
QUITE LIMITED SOUTH OF THE WI BORDER THROUGH EARLY EVENING AND
LIKELY LIMITED TO ONLY A FEW FLURRIES ACROSS FAR NORTHERN PARTS OF
THE IL CWA INTO EARLY EVENING. MID LEVEL TROUGH AXIS THEN PASSES
EAST OF THE AREA BY AROUND 03Z OR SO...ENDING WHATEVER MEAGER PRECIP
THREAT EXITS. TIME/HEIGHT SECTIONS FROM MODELS INDICATE VERY MOIST
BOUNDARY LAYER OVERNIGHT...SUGGESTING LOW CLOUDINESS WHICH APPEARS
TO BE QUITE OVERDONE PARTICULARLY IN WRF WHICH OFTEN DISPLAYS SUCH A
BIAS. THUS WOULD EXPECT A DECREASING TREND IN CLOUD COVER ESPECIALLY
FARTHER WEST/SOUTH OVERNIGHT.

ANOTHER STRONGER SHORT WAVE DIGS ACROSS THE UPPER MIDWEST AND GREAT
LAKES REGION LATE SUNDAY...WITH GUIDANCE AGAIN MAINTAINING BEST
POTENTIAL FOR PRECIP NORTH/NORTHEAST OF THE CWA. WARM ADVECTION ON
INCREASING SOUTHWEST LOW LEVEL WINDS SUNDAY SHOULD SUPPORT MILDER
TEMPS AND HAVE GONE ABOVE MOST GUIDANCE WITH HIGHS AROUND 40. SFC
LOW PASSES ACROSS NORTHERN LAKES AND DRAGS COLD FRONT ACROSS THE
REGION SUNDAY EVENING...WITH COOLER TEMPS MONDAY/MONDAY NIGHT AS
COLD ADVECTION AND HIGH PRESSURE RIDGE AFFECT THE AREA THROUGH
TUESDAY MORNING.

FLOW BECOMES INCREASINGLY ZONAL ALOFT BY MID-WEEK AS BROAD UPPER
RIDGE SPREADS ACROSS THE CONUS...AND LONG WAVE TROUGH MOVES TOWARD
THE WEST COAST. THIS SETS UP PROLONGED PERIOD OF SOUTHWEST LOW LEVEL
FLOW AND WARM ADVECTION RESULTING IN SLOWLY INCREASING TEMPERATURES
AND DEW POINTS THROUGH FRIDAY. HAVE CONTINUED TREND OF PREVIOUS
FORECAST WHICH UNDERCUTS GFS/MEX GUIDANCE A BIT EARLY ON DUE TO
LINGERING SNOW PACK...THOUGH STILL APPEARS TEMPS WILL RISE INTO THE
40S AND EVEN 50S ACROSS AT LEAST PORTIONS OF THE FORECAST AREA BY
THURSDAY/FRIDAY. GFS/ECMWF BOTH PULL 50+ SFC DEW POINTS INTO THE
AREA BY THE END OF THE WEEK WHICH SUGGESTS CLOUDS/FOG/DRIZZLE OR
LIGHT RAIN MAY BE A FACTOR AS SERIES OF WEAK AMPLITUDE MID LEVEL
IMPULSES EJECT OUT OF WESTERN TROUGH...BUT IT BEATS SUBZERO TEMPS
AND 20 INCHES OF SNOW! STRONGER SHORT WAVE DEPICTED IN LONGER RANGE
FORECASTS ACROSS THE UPPER MIDWEST FRIDAY...WITH FAIRLY DEEP SFC LOW
TRACKING NORTH OF THE AREA AND PUTTING CWA IN SPRING-LIKE WARM
SECTOR FRIDAY...BUT THIS IS STILL FEBRUARY...AND COLD FRONT SWINGS
THROUGH LATE FRIDAY WHICH BRINGS US BACK TO MORE TYPICAL LATE WINTER
WEATHER BY SATURDAY.

RATZER

.HYDROLOGY...

330 PM CST

FEBRUARY THAW AS DESCRIBED ABOVE WILL CONTINUE TO INCREASE RISK OF
FLOODING ON AREA RIVERS OVER THE NEXT WEEK. CURRENT OBS AND NOHRSC
REMOTE SENSING OF SNOW PACK...2 TO NEARLY 4 INCHES OF LIQUID
APPEARS AVAILABLE AS SNOW MELTS. SLOW MELTING OF THIS SNOW PACK
INTO NEXT WEEK WILL INCREASE RUNOFF INTO AREA RIVERS...WHICH WILL
ALSO AID IN BREAKING UP RIVER ICE AS FLOWS INCREASE. THANKFULLY AT
THIS TIME LITTLE SIGNIFICANT PRECIPITATION IS EXPECTED DURING THE
PERIOD AND THE MELTING WILL BE SOMEWHAT SLOW. FLOWS ON AREA RIVERS
ARE ALSO RELATIVELY LOW AT THIS TIME...MEANING THERE IS MORE
AVAILABLE STORAGE TO ACCOMMODATE SNOW MELT RUNOFF. THE NEXT
PROBABILISTIC FLOOD OUTLOOK WILL BE ISSUED ON THURSDAY...FEBRUARY
17TH.

.AVIATION...

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

* POSSIBLE LOW LEVEL WIND SHEAR DEVELOPING BY 17Z.

MERZLOCK

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

DEEP LOW WILL TRACK WELL TO OUR NORTH THROUGH SUNDAY
NIGHT...THOUGH THANKS TO THE DRY AIR IN PLACE NOT EXPECTING
ANYTHING MORE THAN AN INCREASE IN WINDS...PARTICULARLY JUST ABOVE
THE SURFACE. SNOW COVER LIKELY TO KEEP TEMPS COOLER RIGHT NEAR THE
GROUND WITH A SHARP INVERSION DEVELOPING SUNDAY SETTING THE STAGE
FOR LLWS AS MODELS SUGGEST WINDS AS LOW AS 1000 FT AGL WILL
INCREASE TO 50-60KT. STRONG PRESSURE FALLS TO OUR NORTH WILL
LIKELY RESULT IN SOME GUSTINESS TO THE WINDS SUNDAY AFTERNOON AND
EVENING DESPITE THE SNOW COVER...BUT DONT EXPECT FULL GUST
POTENTIAL WILL BE REACHED DUE TO THE SNOW COVER. LOW/STRONG
INVERSION AND MELTING SNOW COVER COULD RESULT IN SOME MVFR VSBYS
IN LIGHT FOG OR HAZE...PARTICULARLY SUNDAY EVENING...BUT NOT
SOMETHING THAT CONFIDENCE IS HIGH ENOUGH IN AT THIS DISTANCE TO
INCLUDE IN THE TAFS.

IZZI

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

251 AM CST

A STRONG LOW PRESSURE CENTER OVER SOUTHERN SASKATCHEWAN WILL MOVE
TO NEAR THUNDER BAY ONTARIO BY SUNDAY EVENING. THIS LOW IS THEN
EXPECTED TO CONTINUE EASTWARD TO WESTHER QUEBEC BY MONDAY MORNING.
AS THE LOW MOVES ACROSS THE NORTHERN GREAT LAKES MONDAY AND MONDAY
NIGHT...HIGH PRESSURE WILL THEN MOVE ACROSS THE MID MISSISSIPPI
VALLEY. SOUTHWEST WINDS MAY INCREASE TO GALE FORCE BY THIS
EVENING...BUT AS THE LOW CENTER PASSES AND WINDS TURN TO THE
WEST NORTHWEST THIS EVENING...GALE CONDITIONS WILL BECOME MORE
WISESPREAD. THE GALE CONDITIONS SHOULD DIMINISH MONDAY AFTERNOON
AS HIGH PRESSURE BUILDS IN FROM THE WEST.
