Best I can say is measure every hour and Do not fall asleep Saturday night! lol If you measure Sunday morning you'll have false snow totals.





TWC seems bullish. 12-18" down to here?

I'm like right on that ice line. Forecasts are all over the place...either a major snowstorm (+12") or moderate snowfall and icing.



Mount Holly being conservative and noting the difficulties with forecasting this storm:

0z NAM closing the low. Could be interesting but we are so close to the event why even bother. A nowcasting event.

I'm just going to keep on complaining until the weather forecast will give me snow on LI

Yup 0z NAM went south on the precip boundaries. Of course more runs to come but NAM is fairly good mesoscale.

As of right now the Chicago area is looking at 6 inches of snow, possibly more in some areas with lake effect

Yup. NAM with a south trend. 12" for Hartford.

Gotta watch the models till day of, even though we arent forecasters. Changes happen. Stay on top of it with the Mesoscale models. At least 12-24hrs prior.

I'm done looking after tomm morning. Then its radar time

Do you think places on the east coast, like Providence, will avoid an ice storm?

For those that dont know, NWS has hourly graph forecasts. Scroll down your NWS page and look for it.

Easy to read start stop times and details.

I wonder if there will be some flurries for the deep South with the system.

This is what the 18z NAM was showing. Tonight's run not showing as much.
