| A sounding (upper air observation) taken in Valparaiso, IN at around noon (courtesy of Valparaiso University's Department of Geography and Meteorology). This shows that there was a layer of above freezing air aloft that was deep enough to melt all descending hydrometeors into raindrops before they reached the ground. While the temperature at ground level in Valparaiso was above freezing, it was not in portions of northern Illinois. Since this "warm nose" of air aloft was also present in northern Illinois and there wasn't enough cold air present just above ground level there to refreeze the raindrops into sleet, precipitation fell to the ground as rain, where it froze upon contact with various surfaces due to the below freezing temperatures. | A map showing the approximate air temperatures at ground level at noon. Temperatures did not change much over the course of the event, with the 32 degree isotherm (line of constant temperature) remaining confined to areas that were more or less just north of I-88. Note that freezing rain accumulated on some surfaces in some locations where the air temperature was 33 or 34. This was because the temperature of these surfaces was 32 degrees or lower, and the barely above freezing temperatures were melting the icing slower than the freezing rain was accreting. |
