A little snow can cause a lot of problems on the roads. As a snowstorm moved through the Delaware Valley Saturday -- with no more than a coating in some areas and up to 3 inches of snow in others -- it led to slick roads and plenty of minor car crashes.
The NBC10 First Alert Weather team has extended its First Alert from noon until 8 p.m. Saturday for Philadelphia, the Pennsylvania suburbs, the Lehigh Valley and Mercer County.
Snow totals reported so far range from 1 inch to 3 inches. Upper Chester County through Berks County and the Lehigh Valley got the most snow.
Philadelphia and its suburbs, including New Jersey, saw more of a dusting.
By 5 p.m., most neighborhoods transitioned to sleet, freezing rain and drizzle. The mixture was slippery, and led to reports of multiple minor car crashes throughout the area, especially on elevated overpasses and bridges.
By the end of the storm, the Lehigh Valley could get 2-4 inches of snow, while Philadelphia, Bucks, Montgomery and Chester counties can expect anywhere between 1 and 3 inches.
Coastal points won't see accumulation and will primarily experience rain.
State transportation officials reduced speeds and imposed other restrictions on several Pennsylvania roads during the storm.
The Pennsylvania Department of Transportation reduced speeds to 45 mph on highways including Interstate 78 in Berks, Lehigh and Northampton counties, Interstate 80 in Monroe and Carbon counties, Interstate 81 in Schuylkill County and Interstate 380 in Monroe County.
PennDOT urged motorists to avoid unnecessary travel during the storm.
From around 4 p.m. to 7 p.m., warm air will arrive, bringing rain to South Jersey, Delaware and the Jersey Shore. Between 6 and 7 p.m., Philadelphia will get rain, as well.
Neighborhoods north of that, however, can expect to still be seeing snow until it starts turning over to rain anywhere between 8 and 9 p.m., but it will quickly dry out past 9:30 p.m.
The heaviest sleet, freezing rain, and rain should end everywhere by 9 p.m.
Things will dry out by Sunday, but strong winds will mean frigid temperatures throughout the day.
