5 things you need to know about the expected snowstorm

- A major snow storm is headed for the east coast Friday and Saturday. Here are 5 things you need to know about the potential winter blast.

1. Elevated Threat

A new day and our models continue to point towards a significant…even disruptive storm. Early this morning the weather service has elevated the Winter Storm Threat to “HIGH”. It really is remarkable to see the consistency from model to model. Looks right now like snow arrives on Friday. Right now it’s too soon to narrow the timing down. Cold air will be in place so initially we expect all snow. Some mixing will most likely occur along the I-95 corridor at some point.

2. Watch For Changes to Forecast

Bottom line here -- we can only control what we do and what we forecast. We do watch social media and have a good idea of the different forecasts. No doubt your going to see some wild predictions tossed around. We have shown some early model estimates of snowfall. We use this as a guide and have presented it as such on the air and through social media. By late Wednesday or early Thursday we will have enough confidence to post our forecast for snow totals. Take any snowfall maps you see at this point with a grain of salt, as they may change considerably by Friday.

3. Keep in Mind the Rain/Snow Line

If you have lived here for any time at all you probably know how important the rain/snow line is when forecasting snowfall totals along the I-95 corridor. Right now it looks like most snow and the highest totals will be west of I-95. Mixing will no doubt cut down on totals D.C. and east. We will not have a good handle in where this feature will setup until later this week.

4. Heavy Snow, Expect to Shovel

Yes, this will be enough snow to shovel. If you have a snow blower make sure it’s ready to go. With the mixing potential it looks like this will be a fairly heavy snow…not so light and fluffy. Shovel several times during the storm if possible.

5. Travel Delays Expected

Traveling around the region will be extremely difficult this weekend . Expect this to be a very disruptive storm up and down I-95 and west to the Blue Ridge mountains. Worst case scenario --we would see widespread air and train cancelations, and next to impossible road travel on Saturday. This is a storm that has the potential to bring weekend travel to a halt. Regardless, if you have travel plans and you are able to reschedule to an earlier date (Thursday) it is recommended that you do so given the potential. Again, better safe than sorry.
