Beginning Wednesday and not stopping until early Saturday, the Stateline was given its third winter storm in a row. Not to mention it also fell during the latter half of the week, like its two predecessors. With the longevity of the storm, it left behind some rather impressive snow totals even though temperatures remained above freezing most of the time.
Looking at this from the perspective on Northern Illinois as a whole, the Stateline did receive the most snow for this event. It came in three rounds, with the latest round Friday night and early Saturday packing the biggest punch to it. Compared to December, January has been quite an active month. For the entire contiguous United States, 38.3% is covered with snowfall. Compared to this time in December at 28.1%. That shows how much of an active pattern January has seen for the Midwest and beyond.
For the last round of snow, Rockford officially received 4.3". However, one area in the southwest portion of the city received 6.1" of snow! That's the highest snow total that came from this last round Friday night into Saturday. Compared to Chicago-O'Hare, they only received 0.3". The cutoff was sharp, even in a span of 90 miles between the two airports. Most of the Stateline received between 3-5" between Friday night and Saturday morning.
The 72-hour, or 3-day snow totals are impressive as well. The official 3-day storm total for Rockford is 6.1", with nearby areas receiving a tad more. Most of Winnebago County as a whole received anywhere from 6-7", to an isolated 8" over the 3-day period with the surronding counties receiving 3-6".
The temperatures during that period remained mild, with the high temperatures Wednesday through Saturday staying above freezing for the entire time. This, at times contributed to snow melting at the times where it wasn't falling and kept our pavement temperatures warm enough. However, in the late evenings and early mornings the roads were not in the best shape and it definitely kept area plow drivers busy.
Now that the system is past, we look to quiet down but will keep the clouds and mild temperatures with us. Saturday evening we could see some light wintry mix in spots, especially east of Rockford. Untreated surfaces may become slippery and could see a very small glaze of ice on untreated surfaces.
Other than that, Saturday evening into the overnight hours will remain dry. Clouds will stick around all of Sunday and Monday with highs in the lower to mid 30's. Believe it or not, this is a tad above the normal high of 30° and these forecast numbers will continue for the entirety of this upcoming week.
The mid 30's forecast for highs will also contribute to snow melting across the region too. Even beyond this week, the latest outlook from the Climate Prediction Center calls for us to have near to slightly above normal temperatures going through at least the first week of February.
We look to remain quiet for the beginning of the week, but could see isolated flurries come Wednesday. There is a system at the end of next week that we are eyeing as well. but doesn't look to pack a punch as much as the other systems we've received over the last three weeks.
