Tonight, Vermont is expected to see the coldest temperatures of the season—an abrupt reminder that winter still has plenty of strength left. When the mercury drops this far, the cold stops being a background condition and becomes something you can almost feel pressing against the walls. Nights like this reveal how well our homes hold heat, how prepared our systems are, and how small oversights can ripple into bigger problems.
But extreme cold doesn’t have to catch you off guard. With a few well-timed steps, you can help your home stay warm, stable, and efficient through the night. What follows are grounded, practical measures—nothing alarmist, nothing theoretical. Just the things that make the biggest difference when the cold settles in and stays awhile.
1. Lock In Heat Before the Temperature Plummets
Tonight’s cold will search for the tiniest escape routes.
Warmth is lost in places we rarely look: around windows, under doors, through attic hatches, and around plumbing penetrations.
Before the temperature bottoms out:
- Check exterior doors for drafts and reinforce with fresh weatherstripping if needed.
- Close and lock windows to ensure a tight seal—a simple, often overlooked step.
- Cover drafty windows with insulating plastic or heavy curtains.
Think of this as tightening your home’s thermal envelope right as winter tries its hardest to break through.
2. Give Your Home a Heat-Holding Advantage
Insulation is quiet, invisible, and absolutely crucial on nights like this. Heat rises, and the attic is the first place it tries to leave.
A quick evening check can help keep that warmth where you need it:
- Confirm that attic access panels close fully and sit flat.
- Ensure insulation hasn’t shifted, especially near rooflines or eaves.
- Close off unused rooms to concentrate heat in the living spaces you’re relying on tonight.
This is the structural equivalent of putting on an extra layer before heading outside.
3. Set Your Heating System Up for Success
When temperatures drop sharply, your heating equipment works harder than at any other time. Giving it a small amount of attention now can carry you through the coldest hours of the night.
- Replace or clean furnace filters to improve airflow and efficiency.
- Make sure heat-pump outdoor units are clear of snow and ice.
- Verify fuel levels—cold snaps accelerate consumption.
- Keep vents and radiators unobstructed so heat can circulate freely.
Your heating system doesn’t need perfection—it needs a clear path to operate without strain.
4. Protect Plumbing From Freezing Overnight
Extreme cold can freeze pipes faster than most homeowners expect, especially in marginally insulated areas.
To reduce that risk:
- Open kitchen and bathroom cabinet doors to let warm air reach supply lines.
- Let vulnerable faucets drip lightly; moving water resists freezing.
- Know the location of your main shut-off valve in case a pipe does freeze.
Think of plumbing as a system that thrives on circulation and warmth. Tonight, both matter more than usual.
5. Use Curtains and Blinds as Thermal Tools
When used intentionally, window coverings become part of your heating strategy.
- Open curtains during the day to collect solar heat.
- Close them before sunset to trap that heat during the coldest hours.
- For older windows, add a rolled towel or draft snake along the sill for extra protection.
These small steps create a meaningful buffer against the radiant cold creeping in from the glass.
6. Prepare for the Possibility of Overnight Power Issues
Extreme low temperatures and snow-laden branches can strain power lines. While outages aren’t guaranteed, tonight’s weather makes them more likely.
A few simple preparations go a long way:
- Make sure flashlights, lanterns, and portable chargers are ready.
- Verify that carbon monoxide detectors have fresh batteries.
- If you have a safe alternative heat source (like a wood stove), ensure it’s ready for use.
A calm, prepared home stays comfortable even when the unexpected happens.
7. Keep Vents and Exhaust Clear as Snow Accumulates
Combustion appliances require uninterrupted airflow. During heavy snow and wind, vents can become blocked without you noticing.
Before settling in for the night:
- Check that furnace, boiler, and dryer vents are fully clear.
- Ensure the heat pump has space around it to breathe.
- Watch for unusual system shutdowns or odors—both can signal airflow issues.
These are simple, high-impact checks, especially when temperatures drop into the danger zone.
8. Lean Into the Natural Movement of Heat
Warm air rises, pools, shifts, and escapes. A few small adjustments help keep it where it matters:
- Set ceiling fans to low, reverse to gently push warm air back down.
- Close doors to unused rooms, especially those without heat sources.
- Keep hallways open to allow even distribution of warmth.
You’re not forcing anything—you’re aligning your home with the physics of warmth.
Final Thoughts
Tonight’s cold is the kind that defines a season. But a well-prepared home doesn’t just endure it—it handles it with quiet resilience. These steps aren’t complicated, yet each plays a role in helping your home retain warmth, protect its systems, and stay comfortable through the deepest part of the night.
