Here's the latest on the timing of the storm, according to Accuweather:
The storm should arrive between 7 and 10 pm on Wednesday and give us a good 8 to 12 hours of intermittent moderate and heavy snow. We still like our initial prediction of 6-9 inches, but with more cold air in place than forecasters originally thought, we could be in the 10-12" range.
There is a chance this dual low pressure system could bifurcate somewhat and create one of those scenarios where there are two swaths of snow--one to the north of us and one to the south--and we end up with diddly-doo. We don't think that's going to happen, but this storm set-up with two surface lows has been known to dupe us before.
Still no movement from a Watch to a Warning, but we will see that upgrade happen tonight. We surmise it will happen around 10 pm.
Enjoy the rest of your holiday.
