On top of that, rain and snow are expected throughout much of the state for much of the day, hence the large percentage of rain and snow chances. After that, we will warm back up to more seasonable levels and stay that way at least until the next frontal system comes through and brings us more snow.

Temperatures tomorrow will resemble more so the lows that we will be seeing overnight. That is...
