Cold Front Dropping South Across the Western U.S.; Watching Threat for Tornadoes and Flooding in the South

A cold front will push south across the Western U.S. into Tuesday with mountain snow and areas of gusty to high winds. An area of low pressure will form along this front on Tuesday and bring a potential for severe thunderstorms with tornadoes and excessive rainfall in the lower to mid Mississippi River Valley. To the north, heavy snow is possible in parts of the upper Midwest. Read More >

Total Snowfall from the Feb 13-14, 2007 Winter Event

PUBLIC INFORMATION STATEMENT 
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
100 PM CST WED FEB 14 2007

AN INTENSE AREA OF LOW PRESSURE MOVING NORTHEAST ACROSS THE OHIO 
VALLEY BROUGHT HEAVY SNOW AND HIGH WINDS TO NORTHERN ILLINOIS AND 
NORTHWEST INDIANA DURING THE PAST 48 HOURS.  THE SHARP PRESSURE 
CONTRAST BETWEEN THE LOW PRESSURE SYSTEM AND STRONG HIGH PRESSURE 
OVER THE NORTHERN PLAINS RESULTED IN NORTHEAST WINDS GUSTING OVER 40 
MPH ESPECIALLY IN OPEN AREAS.  BLIZZARD CONDITIONS WERE FELT ACROSS 
AREAS SOUTH OF INTERSTATE 80 FROM KANKAKEE TO PONTIAC TO WATSEKA TO 
RENSSELAER AND POINTS SOUTH... ESPECIALLY IN OPEN AREAS AS 
THE STRONG WINDS WHIPPED THE FALLING SNOW.  SNOWFALL AMOUNTS RANGED 
FROM 8 TO 16 INCHES SOUTH OF INTERSTATE 80 AND WHITE OUT CONDITIONS 
WERE FREQUENT DURING THE HEIGHT OF THE STORM.

WHILE SNOWFALL AMOUNTS LESSENED TOWARD THE NORTH... WITH ONLY 2 TO 4 
INCHES REPORTED IN THE ROCKFORD AREA AND ALONG THE WISCONSIN 
BORDER... THE STRONG WINDS WERE A PROBLEM EVERYWHERE... ESPECIALLY 
IN RURAL AREAS.  SNOW DRIFTS UP TO 5 FEET DEEP WERE NOT UNCOMMON AND 
POSED A CHALLENGE TO MANY SNOW PLOWS OPERATORS AND EVEN RESIDENTS 
TRYING TO CLEAR THEIR DRIVEWAYS. 

ACROSS CHICAGOLAND SNOWFALL GENERALLY RANGED FROM 5 TO 11 INCHES.   
THE OFFICIAL MEASUREMENT AT OHARE AIRPORT... 10.2 INCHES... 
WILL GO INTO THE RECORD BOOKS AS THE 51ST BIGGEST 2 DAY SNOWSTORM IN 
THE PAST 123 YEARS.  THE LAST TIME THIS MUCH SNOW FELL AT CHICAGO 
OHARE WAS JAN 21-22 OF 2005 WHEN 11.0 INCHES OF SNOW WAS RECORDED.  
THE 8.8 INCHES OF SNOW WHICH FELL FROM MIDNIGHT TO MIDNIGHT ON 
FEBRUARY 13 2007 SET A RECORD FOR THE SNOWIEST FEBRUARY 13 ON 
RECORD, AND TIED FOR THE 30TH SNOWIEST SINGLE DAY IN CHICAGO WEATHER 
HISTORY... SINCE 1884.  

AT THE OFFICIAL CLIMATE STATION FOR MIDWAY AIRPORT THE SNOWIEST DAY 
EVER TO BE RECORDED DURING THE MONTH OF FEBRUARY WAS SET YESTERDAY 
WITH 9.7 INCHES OF SNOW MEASURED.  THIS SURPASSED THE PREVIOUS 
RECORD OF 9.3 INCHES RECORDED ON FEBRUARY 6 OF 1978.  WEATHER 
RECORDS AT MIDWAY DATE BACK TO 1928.
