What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
307 PM CST WED DEC 12 2012
.DISCUSSION...
302 PM CST
PRIMARY FORECAST FOCUS IS ON LIKELY WET...NOT WHITE...WEATHER
EXPECTED LATE FRIDAY NIGHT THROUGH SATURDAY AS A DYNAMIC UPPER
LEVEL LOW AND ASSOCIATED SURFACE LOW EJECT FROM THE CENTRAL PLAINS
INTO OUR REGION.
SHORT TERM...TODAY THROUGH SATURDAY
A LOOP OF WATER VAPOR IMAGERY FROM MONDAY TO TODAY SHOWS THE UPPER
LEVEL PATTERN REORGANIZING OVER THE US. THE BROAD UPPER TROUGH THAT
HAD BEEN IN PLACE OVER THE CENTRAL CONUS AND PROVIDING SEASONABLY
COLD CONDITIONS THE PAST FEW DAYS IS BEING REPLACED BY ZONAL FLOW
ACROSS THE NORTHERN TIER. A DEEP UPPER LOW ORIGINATING FROM THE GULF
OF ALASKA HAS QUICKLY PROGRESSED SOUTH PARALLELING THE WEST
COAST...MAKING LANDFALL THIS AFTERNOON IN NORTHERN CALIFORNIA.
THERE IS STRONG AGREEMENT AMONGST OPERATIONAL AND ENSEMBLE GUIDANCE
THAT THIS SYSTEM WILL CONTINUE TO DIVE INTO THE SOUTHWEST US...WHICH
WILL FORCE ANOMALOUS UPPER RIDGING FOR MID DECEMBER INTO THE CENTRAL
CONUS...CEMENTING THE MILD WEATHER TO CLOSE THE WORK WEEK IN OUR
NECK OF THE WOODS. THEREAFTER...THE DYNAMIC UPPER LEVEL SYSTEM AND
DEEP ASSOCIATED SURFACE REFLECTION WILL QUICKLY EJECT INTO THE
CENTRAL PLAINS ON FRIDAY AND THEN INTO THE WESTERN GREAT LAKES ON
SATURDAY. CONSENSUS TRACK OF THE SURFACE LOW OVER OR JUST NORTHWEST
OF THE CWA AND THE ANTECEDENT MILD AIR MASS STRONGLY FAVORS THE
PRECIPITATION FROM LATE FRIDAY NIGHT THROUGH SATURDAY BEING IN THE
FORM OF RAIN.
DETAILS...
TONIGHT THROUGH FRIDAY...A LARGE SURFACE HIGH PRESSURE RIDGE WILL
REMAIN STRETCHED FROM TEXAS TO THE NORTHEAST CONUS AND A LOW
PRESSURE SYSTEM WILL MOVE FROM THE CANADIAN PRAIRIES EASTWARD INTO
QUEBEC. THUS...THE CWA WILL BE EMBEDDED IN BROAD SOUTH/SOUTHWESTERLY
FLOW AND SEE DRY/GENERALLY CLEAR CONDITIONS THOUGH THERE MAY BE SOME
OCCASIONAL MID/HIGH CLOUDS FROM SHORTWAVES SCOOTING TO THE NORTH.
HEIGHT RISES AND A SOUTHWESTERLY WARM ADVECTION PATTERN AT 850 MB
WILL CONTINUE THE WARMING TREND STARTED TODAY. HIGHS THURSDAY FOR
MOST AREAS WILL BE IN THE UPPER 40S..THOUGH CANNOT RULE OUT SOME
SPOTS REACHING 50 DEGREES. THERE IS HIGHER ANALOG AND ENSEMBLE
CONFIDENCE IN REACHING 50 DEGREES ON FRIDAY...ESPECIALLY FOR THE
SOUTHERN HALF OF THE CWA. THURSDAY WILL BE A WINDY DAY...WINDIEST
NORTH OF I-80 DUE TO A TIGHTER PRESSURE GRADIENT...WHERE FORECAST
SOUNDINGS SUGGEST POSSIBLE GUSTS UP TO 35 MPH PRIOR TO SUNSET. WINDS
WILL DIMINISH AND BACK SOUTHEASTERLY ON FRIDAY IN ADVANCE OF THE
APPROACHING SURFACE LOW PRESSURE. NIGHT TIME LOWS TONIGHT AND
THURSDAY NIGHT WILL BE ABOVE NORMAL...BUT NOT EXTREMELY SO BECAUSE
OF THE DRY AIR MASS AND THE BOUNDARY LAYER DECOUPLING ENOUGH FOR
DECENT RADIATIONAL COOLING DESPITE SOUTHERLY WINDS CONTINUING
THROUGH THE NIGHT.
CONFIDENCE...HIGH.
FRIDAY NIGHT THROUGH SATURDAY...CLOUDS WILL QUICKLY INCREASE WITH
THE APPROACH OF THE SURFACE LOW PRESSURE FROM THE WEST-SOUTHWEST.
BEST TIMING OF FORCING/UPWARD MOTION AND SATURATION OF THE COLUMN
QUICKLY ARRIVES IN THE FAR WESTERN CWA AROUND/AFTER MIDNIGHT...WITH
CATEGORICAL POPS ARRIVING THERE AND TAPERING OFF TO SLIGHT CHANCE
FOR THE FAR EASTERN PART OF THE CWA. THE CLOUDS AND GOOD WARM/MOIST
ADVECTION WITH SYSTEM WILL KEEP TEMPERATURES MUCH WARMER FRIDAY
NIGHT...IN THE MID TO UPPER 30S...SO FROZEN PRECIPITATION IS NOT
EXPECTED AS PRECIPITATION ARRIVES.
THE PERIOD OF CATEGORICAL POPS ON SATURDAY FOR THE WHOLE CWA HAS
BEEN TIMED TO BETWEEN 12 AND 18Z...AS THE DRY SLOT OF THE UPPER
SYSTEM...SHOWN BY 1000-500 MB LAYERED RH...LOOKS TO PUNCH IN FROM
THE WEST AND SOUTHWEST IN THE AFTERNOON. THE BEST FORCING FROM
FRONTOGENESIS AND POSITIVE VORTICITY ADVECTION ALSO LIFTS NORTHEAST
DURING THE AFTERNOON...SO HAVE TAPERED POPS TO LIKELY AS THE STEEP
MIDLEVEL LAPSE RATES OVER THE AREA AT THIS TIME ARE EXPECTED TO
STILL SUPPORT DEVELOPMENT OF SHOWER ACTIVITY. THESE STEEP MIDLEVEL
LAPSE RATES AND THE OVERALL STRONG DYNAMICS WITH THIS SYSTEM HAVE ME
CONCERNED WITH THUNDER POTENTIAL ON SATURDAY...DESPITE VERY MEAGER
INSTABILITY AND NOT THE MOST IDEAL MOISTURE INFLUX ALOFT. FOR NOW
HAVE INTRODUCED A SLIGHT CHANCE OF THUNDER TO THE FAR SOUTHERN
CWA...THOUGH IT MAY NEED TO BE EXPANDED LEADING UP TO THE EVENT. IT
SHOULD BE NOTED THAT THE TRACK OF THE SURFACE LOW OVER NORTHWEST
ILLINOIS OR EASTERN IOWA AS CURRENTLY MODELED BARES RESEMBLANCE TO
TRACK OF SYSTEMS THAT HAVE PRODUCED BOUTS OF COLD SEASON SEVERE
WEATHER IN OUR AREA. NOT OVERLY CONCERNED WITH SEVERE THREAT FROM
THIS VANTAGE POINT...BUT WITH VERY STRONG WIND FIELDS/DEEP LAYER
SHEAR CERTAINLY IN PLACE...ITS SOMETHING TO MONITOR AS WE GET
CLOSER.
FOR QPF AMOUNTS...FOLLOWED CLOSE TO HPC GUIDANCE...WHICH ROUGHLY
GIVES A RANGE OF ONE HALF TO THREE QUARTERS OF AN INCH OF RAIN OUT
OF THIS EVENT. WELL ABOVE CLIMO PWAT FOR MID DECEMBER WILL BE IN
PLACE WITH THIS SYSTEM AND WITH MUCH OF THE RAIN EXPECTED TO FALL
THROUGH ABOUT NOON SATURDAY...THE RAIN COULD COME DOWN FAIRLY HARD
AT TIMES.
DESPITE THE CLOUDS AND PRECIPITATION...TEMPERATURES WILL BE QUITE
MILD DUE TO THE DYNAMICALLY DRIVEN WARM ADVECTION...WELL INTO THE
40S CWA WIDE...AND POSSIBLY INTO THE 50S FOR THE SOUTHERN CWA. HAVE
RAISED TEMPS SEVERAL DEGREES ABOVE PREVIOUS FORECAST...BUT COULD SEE
NEEDING TO RAISE THEM A BIT MORE IN SUBSEQUENT FORECASTS.
CONFIDENCE...HIGH IN PRECIPITATION OCCURRENCE AND TYPE...MEDIUM/HIGH
IN TIMING...MEDIUM IN QPF AMOUNTS. LOW CONFIDENCE IN THUNDER
POTENTIAL.

WARNING FOR LAKE MI THIS AFTERNOON INTO THU AFTERNOON. WITH LAKE
SURFACE TEMPERATURES IN THE LOWER 40S N AND LOWER TO MID 40S TO
PROVIDE STEEP LOW LEVEL LAPSE RATE UP TO LOW LEVEL INVERSION BASE
AROUND 2K FT ABOVE THE WATER. SW-SSW WINDS BELOW THE INVERSION
PROGGED TO BE IN THE 35-45 KT RANGE FROM LATE THIS AFTERNOON

SURFACE.
FOR IL AND IN NEARSHORE WATERS...NEW GUIDANCE SHOWS LOW LEVEL
WINDS INCREASING TO 20-25 KT BY MIDDAY AND TO 25-30 KT BY EARLY
EVE. SUNNY/MOSTLY SUNNY SKY THIS AFTERNOON WILL ALLOW DECENT
SURFACE HEATING THE AFTERNOON AND DEEPENING MIXED LAYER
THOUGH WINDS ACROSS FAR SOUTHERN LAKE MI PROGGED NOT QUITE AS
STRONG AS FURTHER N OVER CENTRAL AND NORTHERN PORTIONS OF THE
LAKE. WITH WELL MIXED AIR MOVING OFF THE LAND AND OUT A FEW MILES
OVER THE NEARSHORE WATERS THERE MAY HAVE SOME GALE FORCE GUSTS
MEASURED THIS AFTERNOON AND EARLY EVE...ESPECIALLY AT MARINE OBS
SITES WITH ANEMOMETERS POSITIONED ABOVE THE STANDARD 10M
HEIGHT. FAIRLY QUICK DECOUPLING EXPECTED EARLY EVENING AS MAINLY
CLEAR SKY AND DEW POINTS IN THE LOWER-MID 20S F ALLOW SURFACE
DECOUPLING FROM STRONGER WINDS ABOVE THE TOP OF THE DEVELOPING
INVERSION.

MARINE...PREVIOUS DISCUSSION
330 AM CST
A RIDGE OF HIGH PRESSURE EXTENDING FROM TEXAS THROUGH THE OHIO
VALLEY TO NEW ENGLAND AND SOUTHERN QUEBEC WILL REMAIN NEARLY
STATIONARY TONIGHT AND THURSDAY. AS LOW PRESSURE DEEPENS OVER THE
PLAINS...A STRENGTHENING PRESSURE GRADIENT AND STRONG WINDS AT THE
TOP OF THE BOUNDARY LAYER MIXING DOWN TO THE SURFACE WILL LEAD TO
RAPIDLY INTENSIFYING WINDS THIS AFTERNOON. WINDS ARE EXPECTED TO
REACH GALE FORCE OVER THE NORTHERN PORTIONS OF THE LAKE
FIRST...WITH WINDS INCREASING TO GALES OVER MUCH OR THE REMAINDER
OF THE OPEN WATERS BY EARLY EVENING. THE STRONGEST GALES SHOULD BE
OVER THE FAR NORTHERN PORTIONS OF THE LAKE WITH GALES TO 40 KT
LIKELY AND PERHAPS A FEW GUSTS TO 45 KT POSSIBLE. GALES WILL
PERSIST OVER THE OPEN WATERS THOUGH THE NIGHT TONIGHT AND INTO
THURSDAY. A WEAK TROUGH OF LOW PRESSURE AND AN ASSOCIATED WEAK
COLD FRONT WILL BRING AN END TO THE GALES BY THURSDAY AFTERNOON.
AT THIS POINT...EXPECT THE STRONGEST WINDS TO BE OVER THE OPEN
WATERS...WITH WINDS OVER THE NEARSHORE WATERS REMAINING A BIT
LIGHTER...TO 30 KT...SO HAVE GONE WITH A SMALL CRAFT ADVISORY FOR
THE NEARSHORE WATERS AND A GALE WARNING FOR THE OPEN WATERS.
