If you’re wondering what the weather tomorrow is going to look like, you’re not alone. Many people across south-central Pennsylvania are getting ready for what could be the first real plowable snowfall of the season. As someone who checks weather updates constantly (yes, I’m that friend who texts everyone about storms), I know how important it is to be prepared—especially when snow hits during your morning routine.
Here’s a simple, friendly breakdown of what’s coming, so you know exactly what to expect and how to plan your day.
A Winter Weather Advisory Is Already in Place
The National Weather Service has issued a Winter Weather Advisory for the entire Susquehanna Valley from 3 a.m. to 1 p.m. Tuesday. This means travel may become slippery, visibility may drop at times, and delays are possible.
In simple words: tomorrow morning is going to be messy.
Tonight’s Setup: Clouds Increasing & Snow Building In
As we head into the night, clouds will slowly thicken. If you’re a late sleeper, you may not even notice—until you wake up to fresh snowfall.
Here’s the timeline:
- Light snow begins between 3 a.m. and 6 a.m.
- Temperatures hold steady around 30°F
- Roads may turn slick fast, even with just a dusting
If you need to be out early, try to leave extra room in your schedule. Overnight snow tends to surprise people.
Weather Tomorrow Morning: Heavy & Wet Snow for Many Areas
The morning commute will be the toughest part of the day.
Expect:
- Heavy, wet snow—the kind that sticks easily
- Slippery roads and reduced visibility
- Closings or delays for schools and businesses
- 1–2 inches of snow already on the ground by 7 a.m. in many places
If you’ve ever driven on wet snow, you know it can feel almost like slush under your tires. That’s why slowing down and giving yourself more braking distance helps a lot.
Southern Counties Will See Snow, Then Sleet, Then Rain
Some areas won’t stay snowy for long.
Warm air from a coastal system will push into Lancaster, York, and southeastern Adams counties. This means:
- Snow arrives first
- Then a quick burst of sleet
- And finally rain by mid-morning
These locations may only end up with a coating to 2 inches of snow before it melts into a cold, rainy morning.
Rain should taper off around lunchtime.
If you live in these counties, you may still deal with early slick spots, but travel will improve quicker compared to northern locations.









Projected Snow Totals for the Susquehanna Valley
Here’s a simple breakdown of how much snow you can expect:
Most of the Susquehanna Valley
- 2–5 inches
- Snow tapers from west to east after lunchtime
Higher Elevations (north & east of Harrisburg)
- 5–6 inches possible
- Areas like northern Dauphin, Lebanon, Schuylkill, and Northumberland may see the highest totals
If you live in the hills, you already know—higher elevation = more snow sticking around longer.
Tuesday Afternoon & Evening: Roads Improve, But Be Careful Overnight
Once the snow ends, temperatures rise into the low–mid 30s. Road crews should make quick progress because salt works well at these temps.
But keep this in mind:
- Tuesday night lows drop into the upper 20s
- Any wet, untreated spots may refreeze
- Early Wednesday morning could mean icy patches, especially bridges and rural roads
This is one of those sneaky setups where the worst weather is over—but the leftover ice becomes the real problem.
Quick Look at Weather Tomorrow in Potosi, Texas (79602)
If you’re checking the weather tomorrow for Potosi, Texas instead, the story is totally different—no snow here.
- Tonight stays clear with lows near 27°F
- Tomorrow’s high sits around 44°F
- Light wind and very dry air
- Excellent visibility and calm conditions
Perfect day if you’re heading out early or planning outdoor work.
Final Tips to Stay Ready for the Weather Tomorrow
Here are a few practical things you can do before the storm:
- Charge your phone in case of delays or emergencies
- Give yourself extra driving time—icy commutes are never worth rushing
- Lay out winter clothes tonight so you’re not scrambling in the morning
- Check school or work alerts early
- Keep a small emergency snow brush in your car
As someone who’s driven through more winter storms than I’d like to admit, I can tell you—preparation always beats panic.
Conclusion
The weather tomorrow brings the season’s first true snowfall for much of south-central Pennsylvania. Expect slippery morning roads, heavier snow in the higher elevations, and a mix of snow and rain across southern counties. By the afternoon, things improve, but icy spots may return late at night.
Stay safe, drive slowly, and keep an eye on updates. If this storm is just the beginning of winter, staying prepared now will make the next few months much easier.
