Pro tip from the PennLive weather desk:

Do the necessary things today, because Tuesday might be our biggest snowfall of the winter to date, according to latest National Weather Service projections.

What had been a winter storm watch for south central PA at the start of the day is now a full-blown winter storm warning for most of us, and NWS says the most heavily-affected counties in our region will be Cumberland, Dauphin, Franklin, Lebanon and Perry.

But that’s really just the southern end of a larger warning encompassing pretty much everything between Johnstown to the west, Williamsport to the north and Reading to the east.

Total snow accumulations are projected to range from four to eight inches in the Capitol region, and the state Department of Transportation and the Pennsylvania Turnpike Commission have now issued mandatory travel restrictions on several major highways starting at 3 a.m. Tuesday.

The latest from the forecast office in State College shows that rain starting tonight will switch over to snow during the early morning hours, with heaviest accumulations in the Harrisburg area from about 5 a.m. to 9 a.m.

Snowfall rates during that time could be in the 1-to-2 inch per hour range, making the morning rush hour one to avoid if at all possible.

There will be winds, too: NWS speaks of gusts reaching as high as 35 mph during the height of the storm.

Lesser impacts are predicted for Adams, Lancaster and York counties, though they still could get two to five inches of snow, especially in areas north of the Turnpike.

The storm is expected to wrap by early afternoon, according to the latest forecasts, and daytime highs in the upper 30s will give residents and road crews their best chance for clean-up before an overnight freeze, as temps dive into the upper 20s Tuesday night.
