Peoria, Ill. (WMBD) — The weather pattern is expected to remain active as we enter the final stretch of January. Over the course of the next week there will be two storm systems that may produce accumulating snow across the region.
Storm 1 – Saturday Night – Sunday)
Forecast updated at 3:50 PM Friday
An upper-level wave will move out of Colorado and into the Midwest this weekend. While this system will be a heavy snow producer for southeast Colorado, the storm will be in the process of reorganizing as it moves into Central Illinois. Snow is expected to start between 6 pm and 9 pm over the region and continue off and and on through noon Sunday. A few snow flurries may linger in to the afternoon.
Widespread snow accumulations of 1-2 inches are expected with locally lighter amounts possible east of I-39. Localized accumulations up to 3 inches are possible, but are difficult to pin down at this point. One such area that could see those higher accumulations would be in Knox County. Additional pockets of heavier snow could occur east of the Illinois River but confidence remains to low to include in the forecast at this time. Regardless of snowfall amounts roads will likely become snow covered and slick for Sunday morning drivers.
Storm 2 – Tuesday Night and Wednesday
Models continue to advertise a strong storm system moving across the country on Tuesday and Wednesday of next week. The only sure thing about this storm system at this point is that there will be a pretty significant storm somewhere between the Mississippi River and the Appalachian Mountains, but the exact track of the storm will have major implications on what happens across Central Illinois.
The eastern track would bring the surface low from Texas to Kentucky. This would keep the heaviest snow east of I-55 with the greatest impacts being felt from southern Illinois to Central Indiana.
The western storm track brings the surface low from Texas into SW Indiana. This track would result in a more significant winter storm across the region with moderate to heavy snow and strong winds.
Model guidance varies on exactly where the storm will go, but the recent trend has been to bring the storm further northwest bringing greater impacts to Central Illinois. However, the storm is still located over the Pacific Ocean and the projected storm track will likely fluctuate over the next several days. Be sure to monitor future forecast to see if this system evolves into an impactful winter storm.
