The episode as NWS ILX wrote it up.
A storm system brought showers and thunderstorms to the region on March 4th into the early morning hours of March 5th. As the system slowly began to depart, northwesterly winds transported colder air into central Illinois during the afternoon and evening of March 5th. As temperatures dipped below freezing, some of the residual water began to freeze on area roadways, creating scattered slick spots. Due to the slick conditions, two accidents occurred on I-57. One person was injured.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Lincoln, IL wrote its last area forecast discussion before the first event at Mar 5, 5:15 PM CST, 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 515 PM CST SAT MAR 5 2011 .DISCUSSION... ISSUED 300 PM CST SAT MAR 5 2011 THE OVERALL JET STREAM PATTERN WILL REMAIN NEARLY ZONAL FOR A FEW DAYS IN THE WAKE OF THE DEPARTING STORM SYSTEM. THAT MEANS RISING HEIGHTS LATE THIS WEEKEND INTO EARLY NEXT WEEK...WHICH WILL RESULT IN A WARMING TREND. BY TUESDAY...THE NEXT WAVE IN THE JET STREAM WILL CARVE A TROUGH IN THE PLAINS...EVENTUALLY EJECTING OUR NEXT STORM SYSTEM ACROSS ILLINOIS TUESDAY NIGHT. MORE HEAVY RAIN WILL BE POSSIBLE WITH THAT SYSTEM...WITH RAINFALL AMOUNTS OF 1 TO 1.5 INCHES. WITH NEXT WEEKS SYSTEM...THE 12Z ECMWF HAS FINALLY TRENDED SLIGHTLY SLOWER TOWARD THE MUCH SLOWER GFS AND CANADIAN. THE GFS AND CANADIAN GLOBAL BOTH STILL REMAIN DEEPER AND SLOWER... WITH PROLONGED PRECIPITATION WELL INTO WED NIGHT-THUR. THE 12Z ECMWF NOW INDICATES RAIN CONTINUING LONGER ON WED...BUT NOT WED NIGHT/THUR. WILL CONTINUE TO FOLLOW ECMWF MORE CLOSELY...AS THE PROGRESSIVE NATURE OF THE UPPER PATTERN WOULD FAVOR A SLIGHTLY FASTER SOLUTION. SHORT TERM...TONIGHT THROUGH MONDAY NIGHT ANY LINGERING RAIN SHOWERS HAVE DEPARTING INTO INDIANA...WITH THE REMAINING PRECIPITATION MAINLY LIGHT SNOW OR FLURRIES ACROSS THE WESTERN 2/3 OF THE CWA. THE RADAR RETURNS FOR SNOW HAVE INCREASED IN COVERAGE AND INTENSITY OVER BETWEEN 130 PM AND 2 PM. THROUGH THE DAY SO FAR...ANY STRONGER RETURNS HAVE QUICKLY PULSED BACK DOWN AGAIN. HOWEVER FOR THIS EVENING...WILL HAVE TO ACKNOWLEDGE THE SNOW EFFICIENCY OF THIS TRAILING H5 VORT MAX WITH AT LEAST A MENTION OF FLURRIES THIS EVENING IN THE NE PORTION OF THE CWA. BRISK NORTH WINDS WILL LINGER INTO THE EVENING...BEFORE THE RAPID PRESSURE RISES FINALLY DIMINISH BY MID EVENING. THE SURFACE RIDGE AXIS WILL REACH THE WESTERN BORDER OF IL BY 12Z SUNDAY...HELPING WINDS DECOUPLE IN MOST AREAS BY MORNING. SOME CLEARING IS ALSO EXPECTED AFTER MIDNIGHT FROM WEST TO EAST. LOW TEMPS WILL BE A TOUGH CALL...AND WILL BE DIRECTLY LINKED TO HOW QUICKLY ANY AREAS CLEAR OUT. UPSTREAM DEWPOINTS IN THE MID TEENS WILL BEGIN TO ARRIVE NW OF THE IL RIVER TOWARD SUNRISE. WILL STICK WITH OUR LOWEST LOWS AROUND 20 IN THE NW...AND 29 IN THE SE. WOULD NOT BE SURPRISED IF A FEW LOW SPOTS DROP INTO THE TEENS AROUND SUNRISE. SATELLITE PICS ARE SHOWING THE BACK EDGE OF THE CLOUDS GRADUALLY APPROACHING IL FROM ACROSS IA/MO. THE LOW IS EXPECTED TO INCREASE EASTWARD MOTION TONIGHT...AND FORECAST SOUNDINGS SHOW A DEEP LAYER OF DRY AIR ARRIVING AFTER MIDNIGHT. SO WILL GO WITH THE COLDER MAV NUMBERS. A WEEK H5 SHORTWAVE IS FORECAST TO PASS ACROSS IL ON SUNDAY AFTERNOON/EVENING...BUT MAINLY HIGH CLOUDS SHOULD RESULT...AS LOW LEVELS REMAIN DRY. MONDAY WILL FEATURE INCREASING SOUTHEAST WINDS AND WARMER CONDITIONS...AS A WARM FRONT BEGINS TO DEVELOP ACROSS IL. LONG TERM...TUESDAY THROUGH SATURDAY. ON TUESDAY...THE SURFACE LOW WILL LIFT FROM W OKLAHOMA TO NW MISSOURI BY 00Z WED. ISENTROPIC LIFT AND WARM FRONTOGENESIS WILL COMBINE TO PRODUCE LIFT IN OUR AREA DURING THAT TIME...WITH A FEW SHOWERS POSSIBLE IN OUR WESTERN COUNTIES IN THE AFTERNOON. RAIN WILL BECOME MORE WIDESPREAD TUESDAY EVENING WITH THUNDERSTORMS DEVELOPING AS WELL. HEAVY RAIN WILL BE POSSIBLE TUESDAY NIGHT...WITH MUCH OF THE AREA SEEING ONE HALF TO ONE INCH OF RAIN...AND SOME AREAS UP TO 1.5 INCHES OR MORE. RAIN WILL LINGER ON WEDNESDAY...ESPECIALLY EAST OF BLOOMINGTON TO TAYLORVILLE. PRECIPITATION SHOULD DIMINISH LATER WEDNESDAY AS COLDER AND DRIER AIR ARRIVES ON BRISK NW WINDS. SOME LIGHT SNOW SHOWERS WILL BE POSSIBLE WED NIGHT BEHIND THE LOW PRESSURE SYSTEM. ANY SNOW ACCUMULATION WOULD BE LIGHT. HEAVIER SNOWS WITH THIS SYSTEM WILL BE CLOSE BY TO OUR NORTHWEST...IN IOWA AND INTO WISCONSIN. THE PATH OF THIS LOW WILL NEED TO BE WATCHED CLOSELY. IF IT SHIFTS FARTHER SOUTH AND EAST...WE COULD SEE SOME SNOW FROM THAT STORM SYSTEM. COLDER CONDITIONS ARE LIKELY FOR WED NIGHT THROUGH THUR NIGHT...BUT FRIDAY WILL FEATURE A WARMING TREND AS SURFACE WINDS SHIFT TO A MORE SOUTHERLY DIRECTION. SHIMON && .AVIATION... ISSUED 515 PM CST SAT MAR 5 2011 UPPER SHORTWAVE CAUSING LIGHT SNOW OVER THE TAF SITES WILL MOVE EAST AND BRING AN END TO THE PRECIPITATION BEFORE 03Z. AFTER THAT... EXPECT MAINLY MVFR CEILINGS 1K-2K FT. SOME LOCAL SPOTS MAY KEEP VISIBILITIES 4-6SM FOR A WHILE LONGER AFTER THE SNOW ENDS...BUT THE STEADY WINDS SHOULD MITIGATE ANY SIGNIFICANT VISIBILITY REDUCTIONS. MOST OF THE WINDS SHOULD STAY ABOVE 7KT FROM THE NORTH THROUGH THE NIGHT...THEN DECREASE AROUND 18Z SUN AS THE SURFACE HIGH PRESSURE RIDGE OUT WEST BEGINS TO APPROACH THE MISSISSIPPI RIVER. MODEL LOW LEVEL MOISTURE PROGS SUGGEST THAT THE CLOUDS COULD BREAK UP BY 12Z SUN...BUT THIS IS LIKELY A LITTLE TOO FAST. CYCLONIC FLOW WILL BE CONTINUING THROUGH MUCH OF SUN...AND LOW LEVEL LAPSE RATES WILL SUPPORT STRATOCU REDEVELOPMENT OVER THOSE LOCATIONS THAT SEE BREAKS. 04 && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. &&
