AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
949 AM CST FRI FEB 19 2016

.UPDATE...
948 AM CST

HAVE UPGRADED THE NORTHERN HALF OF THE FORECAST AREA TO A HIGH WIND
WARING FOR GUSTS AROUND 60 MPH THIS AFTERNOON. THE 12 UTC RAOBS AT
DVN HAD AN VERY IMPRESSIVE 70 KT OF WIND AT ONLY 870 MB. AS
TEMPERATURES WARM THROUGH THE MORNING...AND THE CORRIDOR OF
PRESSURE RISES IN THE WAKE OF THE SURFACE FRONTAL TROUGH MOVE ACROSS
THE AREA...WE WILL LIKELY START TO EFFICIENTLY MIX DOWN SOME OF THIS
VERY STRONG FLOW OFF THE SURFACE AS GUSTS. GIVEN THE STRENGTH OF
THESE WINDS...AND THE LIKELIHOOD THAT MOST GUIDANCE HAS BEEN UNDER
FORECASTING THEIR STRENGTH...WE HAVE UPGRADED TO HIGH WIND WARNING.
WE CURRENTLY HAVE LEFT THE SOUTHERN HALF OF THE FORECAST AREA OUT OF
THE WARNING...MAINLY DUE TO THE FACT THAT THE BEST PRESSURE RISES
WILL OCCUR FARTHER NORTH. HOWEVER...WINDS ALOFT ARE STILL VERY
STRONG IN THE SOUTH AS WELL...SO NEAR WARNING CRITERIA WIND GUSTS UP
TO 60 MPH CANNOT BE RULED OUT IN THIS AREA AS WELL.

OTHERWISE...STILL EXPECT NEAR RECORD WARMTH TODAY.

KJB

&&

.SHORT TERM...
329 AM CST

THROUGH SUNDAY...

QUITE AN INTERESTING DAY AHEAD METEOROLOGICALLY AS STRONG AND
FAST MOVING CYCLONE PASSES TO OUR NORTH RESULTING IN STRONG TO
POTENTIALLY DAMAGING WINDS AND RECORD OR NEAR RECORD WARMTH.

RECORD AND IN SOME CASES ALL TIME MONTHLY RECORD WARM
TEMPERATURES WERE OBSERVED THURSDAY AFTERNOON IN THE SAME WARM
SECTOR HEADED FOR OUR AREA TODAY. TEMPS THURSDAY AFTERNOON CLIMBED
INTO THE 80S AND EVEN A COUPLE 90 DEGREE READINGS IN KANSAS AND
OKLAHOMA THURSDAY. IN FACT...AT 3 AM THE TEMPERATURES OVER EASTERN
KS...SOUTHEASTERN NEBRASKA AND OVER WESTERN MISSOURI ARE IN THE
MID TO EVEN UPPER 60S WHICH IS 40-45F ABOVE NORMALS LOWS IN MANY
CASES. IT IS THIS AIR MASS THAT WILL COME SCREAMING INTO OUR AREA
ON VERY POWERFUL WINDS TODAY.

LOCALLY TEMPERATURES HAVE ALREADY BEGUN TO CLIMB AND ANTICIPATE
THIS TREND TO CONTINUE WITH SOME AREAS LIKELY REACHING 50F PRIOR
TO SUNRISE. THE TEMPERATURE FORECAST FOR TODAY IS COMPLICATED BY
THE ERRORS IN THE SNOW DEPTH INITIALIZATION IN THE AMERICAN
MODELS...PARTICULARLY THE NAM...WHICH IS RESULTING IN A VERY LARGE
COLD BIAS. THE ECMWF GUIDANCE HAS BEEN CONSISTENT WITH TEMPS AND
BY FAR HAS THE BEST HANDLE ON TEMPS OVERNIGHT...LENDING CONFIDENCE
TO ITS FORECAST OF NEAR RECORD HIGH TEMPS FOR TODAY. THE ECMWF MOS
GUIDANCE HAS HIGH TEMPS OF 63 RFD...65 FOR ORD AND MDW...AND 68 AT
PNT. HAVE BUMPED UP HIGH TEMPS A BIT FURTHER FROM PREVIOUS
FORECAST FOR TODAY GIVEN ANTICIPATED SUNSHINE (NOT THAT ITS A
REQUIREMENT GIVEN MID 60S AT 3AM IN NW MO) AND STRONG WINDS. WEAK
PACIFIC COLD FRONT WILL MOVE ACROSS THE AREA THIS AFTERNOON AND
COULD RESULT IN TEMPS FALLING THIS AFTERNOON OVER MAINLY WESTERN
PORTIONS OF THE CWA...THOUGH PROBABLY ONLY INTO THE 50S WHICH IS
STILL UNSEASONABLY WARM.

OTHER CONCERN TODAY IS WITH THE WINDS. UNFORTUNATELY...THE LIKELY
ERRONEOUS 2M TEMPS FORECAST TODAY BY THE GFS AND IN PARTICULAR
THE NAM LEAD TO GREATER UNCERTAINTY IN WIND FORECAST. THE WIND
FIELDS WITH THIS SYSTEM ARE REALLY...REALLY IMPRESSIVE AND GIVEN
THE FORECASTED VERY WARM TEMPERATURES MIXING WILL BE DEEPER THAN
FORECAST BY THE NAM AND GFS WHICH COULD TAP INTO THE EVEN STRONGER
WINDS ALOFT. IT REALLY IS A PRETTY CLASSIC HIGH WIND SET-UP WITH
LOW AND MID LEVEL JETS PERFECTLY ALIGNED AND MOVING ACROSS
NORTHERN ILLINOIS THIS AFTERNOON WITH THE MARRYING THE WIND
FIELDS. STRONG PRESSURE RISES THIS AFTERNOON WILL FURTHER HELP
THESE GUSTS MAKE IT TO THE SURFACE AND AM CONCERNED THAT WE COULD
REACH HIGH WIND WARNING CRITERIA (40+ MPH SUSTAINED AND/OR GUSTS
58+ MPH) TODAY. CONFIDENCE ISNT HIGH ENOUGH TO PULL THE TRIGGER ON
A HIGH WIND WARNING..SO WILL JUST CONTINUE THE ADVISORY BUT MAX
OUT WIND SPEEDS IN THE ADVISORY TO THE TOP OF CRITERIA AND MENTION
POTENTIAL FOR PERIOD OF STRONGER WINDS.

TODAY'S CYCLONE WILL MOVE AWAY TONIGHT WITH DIMINISHING WINDS.
WHILE COLD FRONT WILL MOVE ACROSS THE AREA TODAY...THE AIR MASS
BEHIND THIS FRONT IS OF PACIFIC ORIGIN AND WHEN TRANSPORTED OVER
THE ROCKIES DOWNSLOPE WARMING DRAMATICALLY WARMS THE AIR MASS AND
TOMORROW SHOULD BE ANOTHER UNSEASONABLY MILD AND SOMEWHAT BREEZY
DAY...BUT NOT AS WARM OR WINDY AS TODAY.

IZZI

&&

.LONG TERM...
329 AM CST

SUNDAY NIGHT THROUGH FRIDAY...

ANOTHER...SECONDARY COLD FRONT WILL MOVE THROUGH SAT NIGHT AND
BEHIND THIS FRONT AN AIR MASS OF CANADIAN ORIGINS WILL SPILL
SOUTHWARD AND PROVIDE ANOTHER STEP DOWNWARD IN TEMPS SUNDAY.
SOUTHERN STREAM SHORTWAVE...MUCH MORE PRONOUNCED IN THE
ECMWF...COULD SKIRT BY CLOSE ENOUGH TO BRING OUR SOUTHERN CWA A
CHANCE OF SOME SHOWERS SUNDAY NIGHT. OTHERWISE EXPECT DRY
CONDITIONS...EVEN WITH COLD FRONTAL PASSAGES STAGGERED ABOUT EVERY
24-30 HOURS THROUGH THE WEEKEND.

TEMPERATURES NEXT WEEK SHOULD BE MUCH MORE TYPICAL OF LATE
FEBRUARY WITH HIGHS MAINLY IN THE 30S. MEDIUM RANGE MODELS ARE IN
SOMEWHAT DECENT AGREEMENT ON AMPLIFYING A LONG WAVE TROUGH OVER
EASTERN NOAM MID-WEEK...WHICH COULD COOL TEMPS DOWN A BIT BELOW
AVERAGE FOR MID-LATE WEEK. OPERATIONAL GFS/ECMWF DIFFER ON THE
MAGNITUDE OF THE COLD AIR IN OUR AREA...BUT AT THIS DISTANCE
NEITHER LOOKS ANYWHERE NEAR AS COLD AS OUR PREVIOUS COLD SPELL.
PRECIPITATION CHANCES LOOK LOW THROUGH NEXT WEEK...THOUGH SOME
LIGHT SNOW SHOWERS OR FLURRIES ARE POSSIBLE WITH THE SHORTWAVE
WHICH HELPS AMPLIFY THE EASTERN TROUGH MID-WEEK.

IZZI

&&

.CLIMATE...

NEAR RECORD HIGHS ARE POSSIBLE ACROSS THE AREA ON FRIDAY. THE LAST
TIME A 60 DEGREE TEMPERATURE HAS BEEN REPORTED DURING FEBRUARY AT
OHARE WAS BACK ON FEBRUARY 10TH 2009.

THE RECORD HIGH TEMPERATURES FOR CHICAGO OHARE FOR FRIDAY
FEBRUARY 19TH IS 65 DEGREES...WHICH WAS SET IN 1930.

THE RECORD HIGH TEMPERATURES FOR ROCKFORD FOR FRIDAY FEBRUARY
19TH IS 63 DEGREES...WHICH WAS SET IN 1930.

KJB

&&

.FIRE WEATHER...

355 AM CST

VERY STRONG WINDS WILL RESULT IN A HEIGHTENED FIRE DANGER THIS
AFTERNOON. RED FLAG WARNING CRITERIA IS NOT EXPECTED TO BE
MET...HOWEVER INTENSE WINDS WILL MAKE IT DIFFICULT TO CONTROL ANY
FIRES (WILD OR OTHERWISE) WHICH DO OCCUR. RH VALUES THIS AFTERNOON
ARE ONLY OFFICIALLY FORECAST TO DROP TO AROUND 35 PERCENT SOUTH OF
I-80...AND ABOUT 45 PERCENT NORTH...BUT IT IS POSSIBLE THAT BETTER
MIXING COULD ALLOW DEWPOINTS TO FALL LOWER THAN FORECAST. THE
10-HOUR FUEL STICK MOISTURE VALUES ARENT PARTICULARLY LOW
EITHER AND FAIRLY HIGH NEAR THE WI BORDER...HOWEVER QUICKER DRYING
FUELS COULD BE SUSCEPTIBLE TO FIRES.

IZZI

&&

.AVIATION...
FOR THE 12Z TAFS...

WINDS REMAIN THE PRIMARY CONCERN FOR TODAY. STRONG PRESSURE FALLS
AHEAD OF AN APPROACHING DEEPENING LOW AND A STRONG PRESSURE
GRADIENT BETWEEN THE APPROACHING LOW AND A LARGE AREA OF HIGH
PRESSURE OVER THE ERN CONUS HAVE COMBINED TO DRIVE SLY WINDS WITH
GUSTS TO 30KT ALREADY THIS MORNING. MAIN CHANGE TO THE GOING
FORECAST IS TO INCREASE WIND SPEEDS AND GUSTS WITH MAX GUSTS THIS
AFTERNOON TO 45KT. FEEL THAT SKY COVER WILL BE LOWER THAN
PREVIOUSLY ANTICIPATED WITH ONLY A SCT050...WHICH WOULD LEAD TO
MIXING DOWN OF STRONGER WINDS EARLIER..AND ULTIMATELY DEEPER
MIXING THIS AFTERNOON TAPPING THE STRONGER WINDS ALOFT. MUCH OF
THE LATEST MODEL GUIDANCE IS INDICATING 50-55KT WINDS AT THE TOP
OF THE MIXED LAYER THIS AFTERNOON...SO THERE IS THE POTENTIAL FOR
OCCASIONAL HIGHER GUSTS AS WELL.

AS WINDS VEER TO WSWLY THIS EVENING...FOLLOWING THE PASSAGE OF A
COLD FRONT...EXPECT THAT GUSTINESS SHOULD CONTINUE THROUGH THE
EVENING AND INTO THE OVERNIGHT HOURS AS STRONG PRESSURE RISES ARE
GENERATED BETWEEN THE EXITING LOW AND HIGH PRESSURE BUILDING OVER
THE NRN PLAINS AND UPPER MISSISSIPPI VALLEY. BY LATE
TONIGHT...GUSTINESS SHOULD FINALLY DIMINISH AS THE SFC HIGH BUILDS
ACROSS THE REGION AND THE LOWER LEVELS CAN DECOUPLE WITH THE
DEVELOPMENT OF A STRONG NOCTURNAL INVERSION. AT THIS POINT...LLWS
WILL BECOME A CONCERN ONCE AGAIN AS WINDS ABOVE THE INVERSION
SHOULD STILL BE ARND 50-55KT WHILE SFC WINDS DIMINISH TO 10-15KT.

KREIN

&&

.MARINE...
300 AM CST

WITH STRONG HIGH PRESSURE OVER THE EAST COAST AND DEEPENING LOW
PRESSURE TRACKING ACROSS THE NRN PLAINS...SOUTH GALES HAVE RAMPED
UP OVER ALL OF LAKE MICHIGAN. THE LOW SHOULD TRACK ACROSS THE
UPPER GREAT LAKES BY EARLY EVENING. WINDS WILL VEER TO THE WEST
AND REMAIN GALES TO ARND 40KT IN STRONG COLD ADVECTION AND STRONG
PRESSURE RISES BEHIND THE EXITING LOW. WINDS SHOULD BEGIN TO
SUBSIDE LATE FRIDAY NIGHT INTO SATURDAY MORNING AS THE PRESSURE
GRADIENT OVER THE LAKE WEAKENS. HIGH PRESSURE IS EXPECTED TO BUILD
OUT OF CANADA AND SPREAD ACROSS THE WESTERN GREAT LAKES REGION
SUNDAY...LEADING TO A WIND SHIFT TO NORTHERLY...BUT WITH CONTINUES
DIMINISHING WIND SPEEDS. THE CENTER OF THE HIGH IS EXPECTED TO
SLIDE ACROSS THE LAKE SUNDAY NIGHT AND MONDAY MORNING...BRINGING A
PERIOD OF GENERALLY LIGHT AND VARIABLE WINDS BEFORE SETTING UP TO
SELY AGAIN AS THE HIGH MOVES OFF TO THE EAST AND NEW LOW PRESSURE
DEVELOPS OVER THE NRN PLAINS EARLY NEXT WEEK.
