Right now, if you step outside in Nanticoke, you're looking at a crisp 16°F. But honestly? That number is lying to you. With the wind whipping in from the northwest at 12 mph, it actually feels like a brutal 2°F. It’s the kind of cold that bites through a denim jacket in seconds.
Most people checking the weather Nanticoke PA 18634 expect a standard Pennsylvania winter, but this little corner of the Wyoming Valley has its own micro-moods. We’re sitting at an elevation of roughly 696 feet, tucked near the Susquehanna River, and that topography does weird things to the clouds. Tonight, it’s partly cloudy with only a tiny 5% chance of snow, but don't get too comfortable.
The Weekend Reality Check
Friday, January 16, 2026, is going to stay stubborn. We’re looking at a high of 27°F and a low of 16°F. It’ll be cloudy most of the day, but by the time the sun goes down, those snow showers are likely moving in. The chance of precipitation jumps to 35% overnight.

If you've got plans for Saturday, keep the shovel handy. The temperature climbs a bit to 34°F, which sounds better until you realize it’s bringing snow showers with a 35% probability during the day. Humidity is going to hit 70%, making that cold feel damp and heavy.
Nanticoke isn't just "Scranton-lite." Our weather patterns often diverge from Wilkes-Barre because of the specific way the hills funnel wind. While Sunday looks slightly drier with a high of 28°F, the real story starts Monday.

Why the Cold Front is No Joke
Next week is going to be a test of your furnace. Monday, January 19, sees the wind kick up to 20 mph. Even though it’s partly sunny, that high of 26°F will feel much lower. And Tuesday? Tuesday is just mean. We are forecasting a high of only 12°F and a low of 5°F.

Navigating the 18634 Microclimate
Living here means knowing that the "official" forecast at the airport isn't always what's happening on your porch. The hills of Nanticoke, ranging from 499 feet near the river to over 1,000 feet at the highest ridges, create significant temperature variations over just a few miles.
- Watch the Wind Direction: Our current northwest wind is bringing in that dry, Canadian chill. When it shifts southwest—like it will this weekend—we usually see the moisture (and the snow) increase.
- The River Effect: Being near the Susquehanna can sometimes lead to localized fog or "river effect" flurries that don't show up on larger regional radars.
- Infrastructure Preparedness: Nanticoke's hilly terrain means that even a "light" snow of 20% probability can make streets like Noble or Main tricky if the salt trucks haven't made a pass yet.
By Wednesday, January 21, the snow showers return with a high of 23°F. It's a relentless cycle this time of year. But there is a silver lining—daylight is slowly increasing. We're gaining about a minute and thirteen seconds of sun every single day right now.
Actionable Steps for the Coming Week
- Prepare for Tuesday’s Freeze: With a low of 5°F on the way, check your pipe insulation now.
- Saturday Morning Travel: If you’re heading out, do it before noon. The 35% snow chance is weighted toward the afternoon and evening hours.
- Dress for the "Feels Like": Ignore the 16°F on your phone tonight. Dress for the 2°F reality.
- Monitor Local Stations: While national apps are fine, local feeds like WNEP or specialized Nanticoke weather stations (like KPANANTI4) give better ground-level data for the 18634 zip code.
This January stretch is historically the coldest period of the year for the Wyoming Valley. Stay layered, keep the salt bucket by the door, and remember that by March, we’ll be back to those breezy 40-degree afternoons.
