A significant storm system will track across the central and eastern US as we head through the second half of the week. There is high confidence of a storm but lower confidence in exactly where and what type of impacts will occur across Central PA. The rough timing of the system will be anywhere from late Saturday night through Sunday and evening lingering into Monday.
The main concern with this system, at least for our area, will be a moderate to heavy snowfall. It is too early to get specific on exact amounts but several inches appear likely, possibly more if the storm takes the right track. We are at the point in the forecasting process where we can begin to look at what’s more likely. By Thursday night / Friday we should have a better idea on specific snow amounts, timing, and impact.
Much of the model guidance has trended north with the storm over the past 36 hours. This would put Central PA closer to the bullseye of heavy snow. Since we are still 4 to 5 days out from the storm, north trends may continue or a more south, suppressed trend may start. It won’t be until late Thursday or early Friday where we can start to lock in on a more specific scenario. What we are very confident about is the cold that will follow the storm. Whatever snow falls will certainly be sticking around for a while!
