But a Winter Weather Advisory has been issued for the northern part of our region. Times and areas could change but for now, it’s from midnight to noon Friday.

In our immediate area, counties affected are upper Montgomery, upper Bucks, Berks, Lehigh and Northampton. Philadelphia is not covered by the advisory at this time. (Click map for more graphics.)

FOX 29’s Sue Serio says after midnight, the temperature will be above freezing but a strong cold front will move in and rain will quickly change to snow. The storm will move from northwest to southeast, and snow will start spreading into the Philadelphia area by 5am. It should end 10-11am.

Some accumulating snow is a possibility, especially on grassy surfaces since the pavement is still pretty warm.

Temperatures in the 30s will bounce back up to the 40s but then expect another round of flurries, snow or rain showers, or squalls on Friday afternoon.

Models don’t agree on the amount of snow accumulations. They show between a half-inch and more than three inches. Sue predicts the Poconos getting 4”-6”, the Lehigh Valley picking up 2”-4” and Philadelphia seeing about an inch stick. South Jersey and Delaware should see little or no accumulation, but some rain.

After Friday, Arctic air rushes in and will stay with us through the weekend. Saturday and Sunday shouldn’t get above the mid-30s.

For Sunday’s St. Patrick’s Day parade, dress for the cold on Market Street or watch it in the warmth of your home, noon-3pm here on FOX 29. For the start, there will be some sun but breezy. Temperatures will be in the 20s for the start, with the wind chill in the teens. The high should be 36 but there won’t be snow.
