The month of December started off calm with the 1st, a Sunday, having a mix of clouds and sun and temperatures in the 40s and 50s. The 2nd was simliar with more clouds and a few areas of drizzle, but temperatures still reached the 40s. Things were even warmer for Tuesday and Wednesday with clouds, a southern breeze and temperatures in the middle 50s and even 60s on Wednesday. However, pockets of drizzle were still around the area.
Thursday was much colder with high temperatures only in the middle 30s and cloudy skies. Those clouds started dropping snow during the afternoon hours that continued into the early morning hours of Friday. Most areas saw about 1", but some areas along I-70 saw 2 to 4 inches of snowfall. Friday had a few more flurries with a few more areas seeing up to 1" in additional snowfall.
Saturday was sunny and dry, but stayed cold. Sunday started off with some light snow and ended with some light freezing rain. This caused numerous accidents and many schools were closed on Monday. Monday, the 9th, was an ok day with highs in the 20s, but some sunshine. Tuesday was also cold with the morning bringing the first round of below zero temperatures to the area.
We woke up to snow in some places on the morning of the 11th. That was followed by another cold morning with below zero temperatures. Then once again, more snow arrived in central Illinois for Friday. This snow stuck around into Saturday with some parts of the area seeing up to 10 inches of snowfall with the heaviest snowfall of the season by far. Sunday was quiet, but Monday would bring another dusting.
Tuesday, the 17th, was a cold day, but Wednesday started a warm-up that started with temperatures in the 30s. Thursday continued the warmer trend with temperatures in the 40s and Friday also had 40s! However, the warm air came at a cost. Light rain started Friday morning and would only pick up as the weekend went on. Rainfall was heavier on Saturday evening and Sunday morning when 2 to 3 inches of rainfall falled in central Illinois. During this time, there were small bouts of freezing rain, but most of threat, but most of that was northwest of the Illinois River.
The week of Christmas would start off cold, but partly cloudy on Monday, the 23rd. Flurries would be around from the 23rd through the 25th and even some light freezing rain on Christmas day. Temperatures for the week of Christmas went from the teens on Christmas Eve, to the middle 50s by the 28th. The year would end colder teens and single digits for morning lows.
The state of Illinois finished cold with a statewide temperature average of 25.5 degrees. That is 4.4 degrees below the average and makes December 2013 the 20th coldest on record. However, it was 8.4 degrees away from the record cold December. Precipitation was 2.5", which is just a bit below average.
