Winter Weather Advisory For Some; Rain and Thunder For Others

Snowy, icy or rainy weather has moved into the region and will linger through Wednesday.

The type of precipitation that falls depends on how far north you are situated: A Winter Weather Advisory is in effect in parts of the Lehigh Valley, while a Hazardous Weather Outlook is in effect in suburban Philadelphia, including Bucks, Chester, Delaware, Montgomery and Philadelphia counties.

The Winter Weather Advisory in the Lehigh Valley begins at 1 p.m. Tuesday and goes through Wednesday morning. Up to an inch of snow, sleet and freezing rain is expected there.

“Untreated roads will become slippery due to some snowfall and then some icing,” the National Weather Service said in the Winter Weather Advisory.

For the areas under a Hazardous Weather Outlook, three days of rain is expected, with the most falling on Wednesday.

Heavy rain is expected Wednesday, leading to the possibility of localized flooding in areas with poor drainage, according to the NWS. Thunderstorms could accompany the rain Wednesday, bringing wind gusts of up to 50 miles per hour.

The wet weather should clear by Friday, when sunshine and a high in the upper 30s is expected.
