What happened
The episode as NWS DVN wrote it up.
Low pressure developed along a slow moving cold front. Moisture riding up and over this boundary produced widespread precipitation. The precipitation changed from rain to a wintry mix, and eventually snow as colder air sagged south during the day. Numerous minor accidents were reported. Snowfall amounts ranged from 1 to as much as 4 inches, with most of the snow accumulating in areas north of Interstate 80. Most of the precipitation fell as sleet, freezing rain and freezing drizzle along and south of Interstate 80. Ice accumulations were minor.

Area forecast discussion, Feb 14, 3:25 AM CST, 1 hour 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 230 AM CST WED FEB 14 2001 LEADING EDGE OF THE COLD AIR AT THE SURFACE IS PUSHING SOUTH...AND MORE SLOWLY EAST. ARCTIC AIR MASS WILL BRING SIGNIFICANT DROP IN TEMPERATURES WHEN IT FINALLY REACHES THE MID MISSISSIPPI VALLEY. FARTHER EAST...SURFACE BOUNDARY/WIND SHIFT LINE STRETCHES FROM LAKE MICHIGAN TO VCTY STL TO A SURFACE LOW OVER NWRN OK. WEAK WINDS BEHIND THE WIND SHIFT LINE AND AHEAD OF THE COLD SURGE ALLOWED DENSE FOG TO FORM. VISIBILITIES IN SOME AREAS ARE ALREADY IMPROVING AS WIND SPEEDS INCREASE AND PRECIP BREAKS OUT...AND WOULD EXPECT THIS TREND TO CONTINUE. AT THIS POINT...DO NOT EXPECT TO EXTEND DENSE FOG ADVISORY ALTHOUGH WILL WAIT UNTIL THE LAST MINUTE TO MAKE A FINAL DECISION ON THIS. ALOFT...THE NOSE OF THE JET NOW OVER NEW MEXICO WILL MOVE THROUGH NORTHERN MISSOURI TODAY AND INTO NORTHERN ILLINOIS BY THIS EVENING. UNDER THE INFLUENCE OF DEEP SOUTHWEST FLOW ALOFT...THE SURFACE LOW IN OK WILL TRACK NORTHEAST ALONG THE SURFACE BOUNDARY...SLOWING THE PROGRESS OF THE COLD AIR TODAY. CHANGE FROM RAIN TO SNOW WILL DEPEND ENTIRELY ON THE TIMING OF THE INTRUSION OF COLD AIR. TEMPERATURES ALOFT ARE EXPECTED TO SLOWLY COOL TODAY. IF THE COLD AIR AT THE SURFACE SNEAKS IN BEFORE THE REST OF THE COLUMN COOLS...WE COULD BE LOOKING AT FREEZING RAIN/SLEET BEFORE THE CHANGE TO SNOW. ON THE OTHER HAND...IF THE COLD AIR SLOWS...WE WOULD SEE RAIN LASTING LONGER THEN A CHANGE DIRECTLY TO SNOW. SO WHICH OF THESE SCENARIOS IS MOST LIKELY... ACROSS THE NORTHWEST THIRD...TEMPERATURES ARE ALREADY AT FREEZING. DBQ AND MIW ALREADY REPORTING SNOW...WHICH IS SUPPORTED BY MESOETA FORECAST SOUNDINGS. OMEGA AND MOISTURE FIELDS WOULD SUGGEST 1 TO 3 INCHES POSSIBLE BY THIS EVENING AS THE UPPER JET LIFTS OUT. ACROSS THE CENTRAL THIRD...IT WILL TAKE A LITTLE LONGER TO COOL THE WHOLE COLUMN...SO MORE SLEET AND A LATER CHANGE TO SNOW EXPECTED. FOR THE SOUTHEAST THIRD...RAIN SHOULD CONTINUE THROUGH MIDDAY THEN CHANGE TO A WINTRY MIX DURING MID TO LATE AFTERNOON AS THE COLD AIR FINALLY SURGES SOUTH. WILL ISSUE WINTER WX ADVISORY FOR TODAY FOR THE WESTERN SECTIONS WHERE WINTRY PRECIP EXPECTED TO START SOONER AND ICE ACCUMULATIONS WILL BE MORE SIGNIFICANT. TONIGHT COLD AIR DEEPENS...SHUTTING OFF PRECIP. NO CHANGES TO THURSDAY OR LATER PERIODS. .DVN... IA...NONE. IL...NONE. MO...NONE. 33
