Don’t blame the messenger…or the forecaster…
An unsettled weather pattern prevails this week, including into Halloween. There are multiple weather systems to impact the area, starting with tonight, then late Tuesday night into Wednesday, and then finally on Thursday. Each one will have gradually colder air to work with and be stronger.
Thus chances for snow increase and accumulation potential does too, and for Halloween this is especially true north and west of I-55. It’s too early to tell specific details yet at this juncture so remain aware of the latest forecast.
Tonights forecast: Rain mixing with and changing to snow overnight. Low 32F. Winds N at 10 to 15 mph. Chance of precip 100%. About one inch of snow expected.
