The 18Z NAM, hot off the presses, has come in trending bullish for tonight’s event. It basically adds an additional .1 to .15″ of QPF (liquid equivalent) across our area on the western periphery of the precipitation shield compared to previous runs (and with even higher totals down east.) So, it seems the westward trend continues. And while it is difficult to know if this is just a bobble that will settle back with the next run, it is worth noting that upstream snow totals along the Gulf Coast, as well as the northern extent of the precipitation axis have both generally overachieved.
I’ll continue to monitor the latest to see if this translates into that bust potential to the high end. Remember also that this will be will be a dry snow with snow to liquid equivalent ratios running higher than the 10:1 rule-of-thumb. That fact could also help fluff up totals. We’ll see if we have to bump up these numbers later this evening.

My family used to love your updates when watching for WCPS closings! Now they are on opposite sides of the state (AppState and UNCW) and have shared in crazy weather patterns this year- hurricane in the mountains and now snow at the beach! Thank you!
