The bigger snow system is developing now...CURRENT RADAR LOOP HERE
The initial push of light snow will approach later tonight and early Wednesday. Accumulations through noon tomorrow will be around an inch or two. The storm itself begins to rotate southeast then more due east. It will take a while for the snow to converge along the front. Once that happens, the heaviest snow will affect northern Ohio Wednesday evening and overnight.
A WINTER STORM WATCH means there may be hazardous winter weather due to heavy snow. Heavy snow means 7 INCHES OR MORE of accumulation in 24 hours or less. They are issued at least 12 hours (sometimes 24-36 hours) before the hazardous winter weather is expected to begin.
When the storm becomes imminent (inside 12 hours of occurring) or has a high probability of occurring, watches are upgraded to a "WARNING" which was done yesterday for select counties.
Initial snowfall projections are as follows. The track of the storm and its speed will determine if these numbers need to be adjusted later today and this evening.
