ROCKFORD (WREX) – Winter’s grip still holds fast for the Stateline, as Sunday brings with it the chance for accumulating snow.
For those keeping score at home, Rockford has picked up 51.2″ of snow since July 1st, when the official “snow season” starts. By the end of the day today, Northern Illinois may pick up an additional one to two inches of slushy accumulation.
Temperatures today remain well below-average. As a reminder, typical highs for mid-April are around 60-degrees. Colder air is firmly in place across the region, so the best we can expect today is upper-30’s to near-40. When snow is mentioned, surface temperature is crucial this time of year. It appears that temperatures will remain well within the range where snow can make it to the surface without melting.
How much snow are we expecting? If you are live in Boone, Lee, or Ogle Counties, you stand the best chance of seeing between two to three inches. In Rockford, a solid one to two inches of very slushy accumulation is expected. Stephenson County may see the least snowfall, with between a dusting to one inch currently expected.
Mid-April brings a plethora of wild weather to Northern Illinois, but the good thing about late-season snow is it looks like only grassy and elevated surfaces will receive the brunt of the snowfall. Pavement temperatures are generally in the 40’s across the Stateline.
Looking back through the records, which date back to 1905, Rockford has recorded plenty of snow during the latter half of April. Most of the occurrences have features less than three inches. The most snow recorded during the second half of April was 7-inches, which fell way back on April 18, 1912.
This will not be an all-snow event. Some rain is expected to mix in at times. Depending on where exactly high temperatures land could make a big difference in what falls. If temperatures struggle to climb into the mid-30’s, more snow may mix in than rain. However, if highs climb to near-40, we’ll likely see more rain than snow, thereby reducing snow totals in the process.
