Colorado Weather Alert for Denver July 12–13, 2025: Deadly Wind Gusts, Quarter-Size Hail & Overnight Flooding in Forecast – Weather Today & Tomorrow Breakdown
Denver, CO Weather Today July 12 & Weather Tomorrow July 13, 2025: Extreme Thunderstorms, Flood Watch & 90s Heatwave Incoming – Full Forecast Update
Denver residents, brace yourselves — Friday afternoon is forecasted to bring another intense round of severe thunderstorms, with the potential for strong wind gusts💨, large hail🧊, and localized flooding🌊. The National Weather Service (NWS) and Denver7 meteorologists have already declared a Weather Action Day ⚠️, urging people across the metro area and eastern Colorado to stay alert and prepared.
⛈️ Eastern Colorado & Front Range Under Threat
According to Denver7 Chief Meteorologist Lisa Hidalgo, the entire eastern half of Colorado, including the Northern Front Range Mountains, will likely experience some volatile weather conditions today. The biggest threats include:
- 🌬️ Wind gusts reaching speeds up to 65 mph
- 🧊 Hailstones the size of quarters
- 🌧️ Sudden, heavy downpours
“By 2 to 3 p.m., we should start to see storm cells forming across the mountains,” said Hidalgo. “These will quickly move eastward over the plains, bringing turbulent weather into metro areas like Aurora, Lakewood, and Denver itself.”
🌃 Friday Evening: A Stormy Light Show Ahead
Evening commuters might be in for a deceptive calm. Roads may appear dry initially, but by late evening and overnight, storms will intensify, especially over far eastern Colorado. “There’s going to be a real light show over the eastern plains tonight,” Hidalgo added, referring to the increased lightning activity expected overnight, particularly near I-70.
The NWS Boulder office has echoed these warnings, emphasizing that while the risk of a tornado is currently low, the potential for flash flooding and dangerous outflow winds remains high. Stronger storm cells could dump significant rainfall in short periods — a setup ripe for urban and rural flooding, especially in counties located northeast of Denver.
🚨 Flash Flooding Possible Overnight
The flooding threat is serious, especially in far northeastern Colorado. The NWS has reported that heavier storm cells could unleash enough rain to cause rapid water accumulation in low-lying areas.
“Areas east of the foothills and north of I-70 are most at risk for flooding and strong winds,” forecasters noted. Expect small hail, dangerous gusty winds, and flooded roads in these zones. Urban drainage systems may struggle to cope with the downpour, which can lead to flash flooding in minutes ⏱️.
🛶 Water Safety: Caution Urged on Lakes & Reservoirs
Colorado’s lakes and water bodies will also be under threat from the turbulent weather. The NWS has issued a strong advisory for anyone heading out on the water today.
“Stay safe on open water today,” the NWS warned. “Sudden and strong gusty outflow winds can be expected from any showers and storms that develop. Be alert for building clouds and move off the water before they approach. Always wear a life jacket.” 🦺
Boaters, kayakers, and paddleboarders should take extra precautions and ideally avoid open waters during the storm window.
📆 Weekend Forecast: What’s Next?
Friday’s storms are expected to clear out of the Denver metro area by evening, but that doesn’t mean the weather will stabilize for long.
Another round of thunderstorms could return on Saturday, especially over the Southern Front Range, which includes areas south of Denver, like Castle Rock, Colorado Springs, and Pueblo. In contrast, northern areas like Fort Collins and Greeley may experience drier, more stable conditions.
📈 Temperature Outlook:
- Friday & Saturday: Highs in the low to mid-80s 🌡️
- Sunday: A return to summer heat, with highs in the 90s 🔥
🧠 What Should You Do to Stay Safe?
Being storm-ready in Colorado isn’t optional. Here’s what you can do:
- 🏠 Secure outdoor furniture and belongings — winds could send items flying.
- 🌧️ Avoid low-lying areas prone to flooding.
- 🚗 Check road conditions before traveling, especially if you’re heading east on I-70.
- ⚡ Stay indoors during lightning activity — avoid tall trees and open fields.
- 📱 Monitor real-time weather alerts from Denver7 and the National Weather Service.
- 💼 Prepare an emergency kit if you live in a flood-prone region.

Friday’s weather in Denver and surrounding areas is shaping up to be active, fast-changing, and potentially dangerous. With high winds, large hail, and flooding possible, today is not the day to take risks or ignore weather alerts.
Stay inside when possible, be ready to adapt, and keep a close eye on weather apps or news sources. If you’re traveling or spending time outdoors — especially near water — be extra vigilant.
The storm may pass by evening, but storm season in Colorado is far from over. Prepare now and stay safe! 💪🌩️
