Bolaris: Slick Friday morning commute for some
Get ready for a strong storm to produce heavy, wind-driven rain as we move into Saturday.
But first, as some milder air overrides the cold air on Friday, we could see a period of light snow and some freezing rain on Friday morning, especially across our northern and western suburbs. With a light accumulation possible along with some freezing rain, some roadways should become slick in spots. So I would allow for some extra time for your morning commute and again especially if you're driving in from our western suburbs.
Temperatures will climb above freezing by noon so anything falling would be liquid and ending no later than mid-day.
But a major storm will be sweeping up through the Ohio Valley on Saturday. Philadelphia and all of the Delaware Valley will be on the mild Eastern Flank.
I'm looking at the entire region, including our northwest suburbs and even the Poconos, to be liquid.
Instead of snow problems, we'll see flooding. Flash flooding of streams, rivers and creeks seems likely, as the ground is saturated and ice will be melting on land and in the rivers.
Winds will increase out of the mild southerly direction and will gust over 35mph. Tidal flooding is likely along the shore points and Delaware River.
The heaviest rain will fall during the afternoon and evening producing plenty of localized street and highway flooding.
Most of the flash flooding will take place after sunset, making for dangerous travel in flood-prone zones.
The only good news is that temperatures will rise through the 50s.
Sunday will be a clearer, windy and colder day with temperatures closer to normal or just above.
