December, January and February are the three coldest months of the year here so March 1st marks the beginning of meteorological spring.
We will start “spring” with a light snow at times today, tonight and into early tomorrow.
Marginal conditions are present for some lake effect snow so we don’t expect big accumulations. It is possible some areas near the lake shore could see between .5″ to 1″ total by Saturday afternoon. Our .2″ of snow yesterday means we have now just barely surpassed last year’s snowfall through this point of the season (see image above).
A more significant snow could be on the way for early next week.
Both the European model (top image below) and the GFS model keep the heaviest snowfall south of us. Subtract about 1/2″ of snow from the totals forecast for O’Hare for the lake effect today through tomorrow.
That leaves us with somewhere between .5″ and 1″ of fresh snow with this upcoming system.
Stay tuned though since a slight northward change in the track could be the difference between an inch or two and several inches.
