March 7 snow timeline

Snow is expected to be heaviest during the day Wednesday.

Though storm forecasts changed Tuesday afternoon, by Wednesday morning, it was clearer that the storm - instead of moving farther west - will stay more to the east.

Predicted snowfalls from Tuesday are now substantially lower, with all of Cumberland County seeing only 1 to 3 inches of snow Wednesday, according to ABC27 meteorologist Dan Tomaso.

There area that would have seen the highest snowfall - Lebanon and Lancaster counties - are now expected to see only 3 to 6 inches of snow.

The timetable of the storm will be around the same, with the snow falling steadily late this morning and early afternoon, from 10 a.m. to 2 p.m. The storm will quickly taper off from west to east by the evening hours.

ABC27 meteorologists are still tracking a possibility of a snowstorm Sunday, though that has begun to track away from the Midstate.

A weakening area of low pressure moving out of the Ohio Valley will bring some light precipitation Tuesday that will transition to snow showers later in the day.

Another strong coastal storm will then form Tuesday night into Wednesday morning, making for some light snow overnight and lows dropping to around freezing.

The snow will intensify through the region after 7 a.m. Wednesday morning then likely continue through the day. The National Weather Service has issued a winter storm watch for Dauphin, Lancaster and York counties.

The farther west you live, the lower the snowfall totals from the storm will be. Some places west of Carlisle may not see much more than 1 inch of snow. However, getting closer to the West Shore and Harrisburg, 3 to 6 inches of snow is expected.

Areas east of that, including Lancaster County, may see 6 inches to a foot of snow. Snowfall rates of 2 inches per hour are possible during the peak of the storm in eastern locations of the region.

The snow should taper by Wednesday evening's commute, and likely over sooner in the western counties. However, tricky travel will persist through Wednesday night.

ABC27 is also tracking another storm that could deliver some additional rain or snow - or miss the area completely - that could be in the region by the end of the weekend. The timing looks to be Sunday evening into Monday morning if it takes shape.
