Central Pennsylvania will enjoy a dry Saturday with temperatures in the 30s to near 40 degrees before winter weather returns. A quick-hitting system will bring snow to northern areas and a wintry mix to southern regions late tonight into Sunday.

The National Weather Service in State College indicates Saturday will remain dry with high temperatures ranging from the low 30s in northwestern mountains to near 40 degrees south and east of the I-80/I-99 corridor. Light winds and some sunshine make today ideal for outdoor holiday decorations before conditions deteriorate.

Snow will develop after dark tonight across western Pennsylvania, spreading eastward overnight. Areas north of I-80 could see up to three inches of accumulation by Sunday afternoon, with the heaviest amounts expected in northwestern counties. Southern regions will likely experience a wintry mix changing to rain Sunday as temperatures warm. Gusty west winds of 25 to 35 mph will develop Sunday afternoon.

Monday should be dry before a more significant winter storm approaches the region. The Weather Service warns that a potentially impactful winter storm is expected Tuesday into Wednesday, with plowable snow amounts likely across most of central Pennsylvania. Northeast portions of the state face the highest probability of receiving more than six inches of snow.

Forecasters recommend monitoring updates closely, especially for those with travel plans Tuesday and Wednesday, as winter storm watches may be issued in the coming days if confidence in heavy snow increases.

Below normal temperatures will persist through early December, with lows possibly dropping into the teens or single digits later in the week as the active storm pattern continues.
