PHILADELPHIA (CBS) — The past few days have been colder than average with highs only in the 40s with some flurries around, but a better chance to see some widespread snow will arrive on Tuesday.  A weak disturbance developing out in the central U.S. will quickly track across the country over the next 24 hours with not much amplification in the jet stream.  This is not the best news for snow lovers, as the system will move fast and will not have abundant moisture to work with.  But this nuisance storm may have enough snow to disrupt some travel on Tuesday.

Monday will be a nice day as high pressure remains in control with sun & clouds and highs near 50 degrees.  Clouds will then thicken up Monday night but this should allow temperatures to stay just above freezing.  Precipitation will begin by mid-morning Tuesday and continue into the afternoon and end sometime mid to late afternoon.  The timing of the storm has been faster so the Tuesday morning commute will be impacted with a mix of rain & snow all snow, depending where you are located.

As of now, areas from Philadelphia on southward may see a mix of snow and rain with a coating to an inch of slushy snow possible.  Locations just north and west of Philadelphia up to the Poconos will see mainly all snow with a band of 1-2″ possible just north of Philadelphia.  This will all depend how much moisture is available and where the best jet stream dynamics set up across the region.  Temperatures aloft in the atmosphere will be below freezing but surface temperatures through the day on Tuesday will remain above freezing.   So the snow will have to fall heavily for accumulation to occur on the main roadways.
