Snow Into Tonight Winter Storm Warning
In what could be the last accumulating snow threat for the winter season we are starting to see everything in the atmosphere beginning to rev up Radars in Pennsylvania and to the south are starting to rev up now with precipitation developing rapidly.
What falls this afternoon will have a tough time sticking to roads due to the borderline temperatures and the seasonal factors that March brings with the strengthening sun angle. However after about 3 or 4pm the sun angle issue rapidly diminishes and temperatures will correct down to between 31 and 33 and snow will begin to accumulate quickly. The height of the snow intensitiy should be from 4pm until about 1am or so.
The map loop above is the HRRR model which is a short range model with a simulated radar view. It runs from 4pm on the first frame until 2am on the last. This shows that after midnight snow begin to taper off and end. It is possible that some sleet gets into the mix toward the end. The fast moving nature of the storm prevents accumulations from getting too out of hand. I'm forecasting a general 3 to 6 inch snowfall with a band of 6 to 8 possible over some areas. Some will finish on the high end and some will finish on the low end.
After this storm moves away, very cold air for this time of year will begin to move in on Monday and it will be with us for much of this coming week.
