I’ve been listening to the TV forecasts tonight and I’m hearing dire forecasts for Wednesday morning’s commute. From what I see with the latest NAM model, snow is NOT likely for Philadelphia or the immediate northwest suburbs. The upper atmosphere looks too warm for snow early Wednesday morning around here..
It’s not clear if ground temperatures will be above freezing, so some icy conditions may be possible. The NAM delays the precipitation onset until about 8 am in PHL.
We won’t know for sure until the Tuesday night model runs.
