Here's a look at the weather highlights for January 2013.

2013 got off to a cold start with snow on the ground from snow on December 31st.  Temperatures only got into the 20s for highs on the first and dropped into the middle single digits for the morning of the 2nd. 

Clouds increased on the night of the 2nd and by Thursday morning, the 3rd, we were mostly cloudy.  The clouds would stick around into the evening hours before clearing out on Friday morning.  Friday was a sunny day with temperatures a bit warmer. 

The first weekend of 2013 had a bit of snow and chilly temperatures.  The light snow was limited to Saturday and Sunday was a sunny day.  Highs were around 30 for both days.  After that, the warm-up was on with highs reaching into the upper 30s on Monday and into the 40s on Tuesday and 50s on Wednesday.

Our nice weather took a one day break on Thursday the 10th.  We woke up with warm conditions, but rain moved in around noon and stuck around into early Friday morning.  Some places reported over 1" of rainfall, which is about a third of what we normall get in January. However, Friday was a sunny and beautiful day with highs in the upper 50s and lower 60s, which broke a few record highs.

The weekend wouldn't hold on to the beautiful weather.  Saturday started nice, but the end of the day brought rain back into the area.  Some of that rain became freezing rain by the early morning hours of Sunday.  There was a break from the freezing rain early on Sunday, but by about noon, more of the freezing rain was back.  There weren't any large reports, but there was enough to make things slick.  Also, some areas saw 1" of rain before the freezing began. 

The cold air that followed the front stuck around for the next several days.  Monday only had highs in the middle 20s and Tuesday struggled to around 30. Wednesday was a bit warmer, but didn't feel warmer because of a stronger southwest wind.

There was a bit of a step back on Thursday, the 16th, as we only go to 30 with a noticable wind.  However, we enjoyed a quick step into the 40s for Friday and Saturday, but the wind continued to be an issue.

Sunday was the beginning of quite the cold blast.  We only had highs in the middle to upper 20s. 
By Monday morning we were in the single digits and we only made it to the middle teens by that afternoon. Tuesday morning our temperature dropped down to near zero with wind chills nearing twenty degrees below zero. We saw some sunshine on Tuesday, but highs only got to the middle teens. Another round of single digit lows were noted on Wednesday morning, but the wind was much calmer and the wind chills stayed above zero.  

The cold wind returned Thursday morning with temperatures around 5 for morning lows and winds around 10 mph.  That created a wind chill near 10 degrees below zero.  Thursday afternoon had less wind and temperatures around 20.  Winds were calmer in the afternoon.  Friday morning, the 25th, started with very light snow for some parts of central Illinois.  By the afternoon hours we had sunshine with about a 20 mph wind that brought wind chills down towards the lower 20s. 

The final weekend in January would have a cold Saturday and an icy Sunday.  Highs on Saturday were in the upper 20s.  Sunday Morning we woke up to rain moving in with temperatures in the middle 20s.  However, any major freezing rain was avoided because temperatures shot up to 33 to 35 degrees very quickly.  What could have been a mess, was avoided, but a nice soaking rain did make Sunday a dreary day. 

Monday was a cloudy and very warm day with most places in the middle 50s.  The evening brought a large amount of dense fog that triggered dense fog advisories for most of the area.  We were even warmer on Tuesday with highs in the middle 60s.  That set record highs across the area.  Also, the evening brought storms that were strong to severe and a lot of rain. Some isolated areas saw up to 2" of rainfall. The city of Ashmore was the hardest hit from the strong to severe storms.

The month would end cold.  The 30th had highs in the middle 50s, but by 6 PM, temperatures were in the 30s.  We woke up on the 31st to temperatures in the lower to middle teens, but a 20 mph wind pushed the wind chill below zero.  The afternoon was only in the lower 20s, with wind chills barely breaking zero.
