What Is a Pinpoint Weather Alert Day?

A Pinpoint Weather Alert Day is a designation used by meteorologists to highlight periods when severe or impactful weather is expected. Unlike general forecasts, these alerts are issued when conditions—such as heavy snow, ice, or high winds—are likely to disrupt daily life. For Denver, this often means:

  • Significant snow accumulation (typically 3+ inches in a short time).
  • Hazardous road conditions, including black ice and reduced visibility.
  • Potential school or business closures.
  • Delays or cancellations for flights at Denver International Airport (DIA).

These alerts are not just warnings—they’re a call to action. When you see a Pinpoint Weather Alert Day in the forecast, it’s time to adjust your plans and prepare for potential challenges.

Why Does Denver Get So Many Snow Alerts?

Denver’s geography makes it uniquely prone to rapid weather shifts. Nestled near the Rocky Mountains, the city experiences:

  • Orographic lift: Moisture from the Pacific is forced upward by the mountains, cooling and condensing into snow.
  • Chinook winds: Warm, dry winds can melt snow quickly—but they can also create sudden temperature drops when they shift.
  • Urban heat island effect: Denver’s concrete and asphalt absorb heat during the day, leading to icy refreezing overnight.

This combination means that even a small snowstorm can escalate quickly, especially overnight when temperatures plummet.

Denver’s Friday Snow Forecast: What to Expect

According to the latest data from the National Weather Service (NWS) and local meteorologists, here’s what’s on the radar for Friday’s overnight snow:

Timing and Accumulation

  • Start time: Snow is expected to begin late Friday evening, around 9 PM–11 PM.
  • Peak intensity: The heaviest snowfall will likely occur between midnight and 4 AM.
  • Accumulation: 3–6 inches are possible in Denver proper, with higher totals (6–10 inches) in the foothills and western suburbs like Lakewood, Golden, and Evergreen.
  • End time: Snow should taper off by Saturday morning, but lingering flurries may continue until noon.

Impact on Travel and Commuting

Overnight snow often leads to treacherous morning commutes. Here’s what to watch for:

  • Icy roads: Even if snow stops, black ice can form on bridges, overpasses, and shaded areas.
  • CDOT and plow delays: The Colorado Department of Transportation (CDOT) will deploy plows, but major routes like I-25, I-70, and C-470 may still have slowdowns.
  • Public transit: RTD buses and light rail may experience delays. Check RTD’s website for updates.
  • Air travel: DIA is likely to see flight delays or cancellations, especially for early Saturday departures.

Temperature and Wind Chill

Temperatures will drop to the low 20s°F overnight, with wind chills making it feel like the teens. Dress in layers if you’re heading out, and watch for signs of frostbite or hypothermia.

How to Prepare for Denver’s Overnight Snow

Being proactive can save you time, stress, and even money. Here’s your checklist to stay ahead of the storm:

1. Winterize Your Vehicle

If you’re driving Friday night or Saturday morning:

  • Check your tires: Ensure they have at least 3/16” tread depth (use the pey test). Consider snow tires if you frequently drive in the mountains.
  • Top off fluids: Antifreeze, windshield wiper fluid (rated for -20°F), and gas (keep your tank at least half full).
  • Pack an emergency kit: Include a blanket, flashlight, ice scraper, jumper cables, snacks, and a portable phone charger.
  • Clear snow completely: Don’t just peel a “porthole”—clean your entire car (roof, windows, lights, and sensors) to avoid fines and improve visibility.

2. Adjust Your Travel Plans

  • Leave early: If you must drive Saturday morning, give yourself extra time for slow traffic and plow routes.
  • Use real-time traffic apps: COtrip (CDOT’s tool) or Google Maps for live updates.
  • Consider remote work: If possible, ask your employer about working from home Friday or Saturday.

3. Protect Your Home

  • Insulate pipes: Wrap exposed pipes to prevent freezing. Let faucets drip slightly overnight.
  • Test your heating system: Ensure your furnace or space heaters are working efficiently.
  • Stock up on supplies: Have bottled water, non-perishable food, and batteries in case of power outages.
  • Shovel strategically: Clear snow from sidewalks and driveways early to avoid ice buildup (Denver ordinances require this within 24 hours).

4. Stay Informed

Denver Snowstorm FAQs

Will Schools Be Closed?

Many Denver-area school districts (including Denver Public Schools, Jefferson County, and Douglas County) make closure decisions by 5 AM. Check their websites or local news for updates.

What About Power Outages?

Xcel Energy prepares for winter storms, but outages can still occur. Report outages via the Xcel Outage Map or by calling 1-800-895-1999.

Is This a “Bomb Cyclone”?

No—while Denver has seen “bomb cyclones” in the past (like the historic 2019 storm), Friday’s system is not expected to intensify as rapidly. However, always monitor updates in case conditions worsen.

Can I Still Hike or Ski?

If you’re headed to the mountains (e.g., Rocky Mountaiational Park or I-70 ski resorts), check CDOT’s mountain passes report for chain laws or closures. Avalanche risk may also increase—visit the Colorado Avalanche Information Center for backcountry safety.

After the Storm: What’s Next?

Melting and Refreezing

Saturday’s high is expected to reach the mid-30s°F, which will help melt snow on roads. However, overnight refreezing can create icy patches by Sunday morning. Stay cautious, especially in shaded areas.

Shoveling Safety

Shoveling snow is a common cause of heart attacks in winter. Follow these tips:

  • Take frequent breaks and stay hydrated.
  • Use a smaller shovel to lift less weight per scoop.
  • Push snow instead of lifting when possible.
  • Watch for signs of chest pain, dizziness, or shortness of breath.

Helping Neighbors

Denver’s strong community spirit shines during snowstorms. Consider:

  • Checking on elderly neighbors or those with mobility challenges.
  • Shoveling sidewalks for pedestrians and mail carriers.
  • Donating to local shelters (e.g., Denver Rescue Mission) that support homeless populations during cold snaps.

Denver Weather Trends: What’s Ahead?

Friday’s snow is just one piece of Denver’s winter weather puzzle. Here’s what to expect in the coming weeks:

La Niña’s Influence

The La Niña climate pattern (cooler Pacific waters) typically brings drier, warmer winters to southern Colorado but more snow to the northern Front Range. Denver may see near-average snowfall this season, with occasional Arctic blasts.

Long-Range Forecast

  • December–February: Expect 2–3 more significant snowstorms, with the highest chances in January.
  • Spring snow: Denver’s latest snowfall on record was June 12, 1947—so don’t pack away your boots just yet!

Climate Change and Denver’s Future

While Denver’s snowfall varies year to year, climate change is shifting patterns:

  • Warmer temperatures may lead to more rain-snow mixes instead of pure snow.
  • Shorter snow seasons but potentially more intense storms when they occur.
  • Increased fire risk in dry periods following snowmelt.

Staying informed about these trends can help you plan ahead for future winters.
