Happy Christmas Eve Everyone!
I would like to give you a quick weather update for anyone out traveling across the area today. Snow entered the area from the southwest this morning and will continue through this afternoon.
Due to the colder temps across the area, the snow is not having any trouble collecting on the road surfaces, so slick conditions are expected. If you will be out traveling today, please take it slow!
With that being said, here is the latest on what we can expect across the area as far as snow totals from the NWS in Chicago/Romeoville:
I have posted the forecast from the NWS here, because their forecast aligns very well with what the models are showing. Snow to water ratios for this system look to be pretty high, in the 12:1-15:1 range, which means for each inch of water that is 12-15″ of snow, or a really fluffy snow. Unfortunately we WON’T see snowfall totals like that though because we only have total liquid precip for this system across the area in the 0.05-0.14″ range. When you multiply that by 15 (with a ratio of 15:1) you will get 0.75-2.1″ of snow. That forecasted 1-2″ range above falling pretty close to that range.
Winter Weather Advisories are in places across any place in the purple shading, where 2-5″ of snow is possible. Then in the pink shading over Northwestern Indiana, those are Winter Storm Warnings where 4-7″ of snow is possible. Across Ogle, Winnebago, and Boone County, a Special Weather Statement has been issued, which I will post below:
SPECIAL WEATHER STATEMENT National Weather Service Chicago/Romeoville IL 403 AM CST Sun Dec 24 2017 Winnebago-Boone-McHenry-Lake IL-Ogle- 403 AM CST Sun Dec 24 2017 ...Slippery Travel Developing This Morning... Snow will impact the busy holiday travel day today. Snow will develop across northern Illinois around daybreak. The snow will be light and fluffy, but should quickly accumulate on pavement this morning into early afternoon. This will create slippery travel conditions on untreated roads. Total snow accumulations of 1 to 3 inches are expected. Heavier snow will occur as you head farther south. Snow will taper off during the mid afternoon hours across northern Illinois, lasting longest near the lakefront. Be prepared to slow down and allow extra time to reach your destination today.
Again, please drive slowly today and use plenty of extra caution so you can arrive at your destinations safely. For the latest on road conditions I have included a phone number and link to a website you can visit and be sure to keep checking back for the latest. Be safe everyone!
