Philadelphia Weekend Weather Outlook- Tues PM
As mentioned yesterday, the computer models are looking more and more winterlike.
The latest GFS model has a changed the forecast for the upcoming week/weekend-- it shows a deeper and broader upper trough developing during the week, with heavy rain and windy conditions for late Wednesday into Thursday. Colder air moves in later Thursday through Friday, as the winds subside.
Once the cold air moves in on Friday, the latest GFS has a fast moving low developing and moving up the coast on Saturday, possibly giving us some wet snow late Saturday. Surface temperatures will likely be too warm for accumulation, but some light wet snow or snow mixed with light rain is still a possible for Saturday afternoon into early evening. Areas to the south and east of Philadelphia will likely have more precipitation but temps might be a bit warmer.
With ongoing changes in the computer models, we'll have to wait to see the final track of this coastal low.. Expect a cold weekend, certainly colder than it has been since the end of last winter.
