What could be the biggest snowstorm of the season should arrive by daybreak Thursday.

It could be quite impressive. As usual, the I-95 corridor may serve as the boundary separating heavy snow of more than 5 inches - across portions of South Jersey and Delaware -  with lesser accumulations to the north and west. So far this season, the deepest snow recorded in Philadelphia was a little over 4 inches.

Any snow falling in the region this evening will change over to sleet and freezing rain, although we could see a longer period of freezing rain north and west of I-95 before it completely changes over to rain.

Wednesday's forecast calls for more rain.

The specific amounts I expect to accumulate on Thursday will be another hair-raising weather call as this entire winter season has been a bunch of storms that have just grazed us.
