If you’ve lived in Western New York for more than five minutes, you know the drill. One second it’s sunny in Elmwood Village, and the next, you’re staring at a wall of white on the Thruway near Lackawanna. It’s chaotic. That’s why WIVB Buffalo weather radar—branded as News 4’s "4 Warn Weather"—ends up being the most-refreshed page on a lot of local phones.
Look, weather apps are everywhere. Every iPhone has one pre-installed. But there’s a massive difference between a generic global algorithm and a radar feed calibrated specifically for the weird, moisture-heavy physics of Lake Erie.
The Lake Effect Problem
Buffalo weather isn't normal. It’s localized. Most national weather sites use a broad-brush approach that misses the "snapping" effect of a lake-effect band. These bands are often only a few miles wide. You can be in the sun while your cousin three miles south is shoveling two feet of powder.
WIVB Buffalo weather radar uses the NEXRAD (Next-Generation Radar) data from the National Weather Service station in Cheektowaga (BUF), but they layer it with their own proprietary high-resolution modeling. This matters because the "4 Warn" team—led by veterans like Todd Santos—focuses on the "ground truth." They aren't just looking at the sweep; they’re looking at how that sweep translates to the specific topography of the Boston Hills or the Tug Hill Plateau.
Why the 4 Warn Radar Feels Different
Most people just look for green or red blobs. But if you're trying to figure out if you can make it to the Bills game without getting stuck in a drift, you need to understand the "velocity" and "correlation coefficient" data that News 4 often highlights during live breaks.
Velocity tells you which way the wind is blowing the snow within the cloud. Correlation coefficient is even cooler—it helps the meteorologists figure out if they’re looking at rain, snow, or "noise" like birds or insects. During those messy spring transitions where it's half-rain and half-slush, this is the only way to know if your driveway is about to turn into an ice rink.

It’s about precision.
You’ve probably noticed that News 4 emphasizes their "Live Doppler" capability. While the data primarily originates from the government’s S-band radar, the way WIVB processes it for the web and mobile app involves a faster refresh rate than many "free" weather apps that only update every 10 or 15 minutes. In a Buffalo blizzard, 15 minutes is the difference between being safe at home and being stranded on the 400.
Real-World Reliability: The 2022 Blizzard Lessons
Remember the Christmas Blizzard of 2022? National models were struggling with the sheer speed of the pressure drop. Local stations, including WIVB, were the ones pointing out the specific "flash freeze" timing.
The WIVB Buffalo weather radar was showing the transition from rain to a total whiteout with eerie accuracy. While national outlets were talking about "New York State weather," the local radar was showing the exact moment the wind shifted to a deadly 70-mph gust profile over the city’s waterfront.
Honestly, the tech is only half of it. It’s the context. When you see a red band on the News 4 radar, the meteorologist on air is telling you, "That’s not just heavy snow; that’s thunder-snow near Orchard Park." That human layer over the raw radar feed is why people stay loyal to local news stations even in the age of TikTok weather influencers.

How to Actually Use the Radar Without Getting Overwhelmed
Stop just looking at the "Futurecast." Most "Futurecast" tools are just math guesses. Instead, toggle to the "Past 1 Hour" loop.
Why?
Because in Western New York, the trend is your friend. If you see the band drifting north-northeast, you can plot your own path. If the band is stationary, it’s building.
The WIVB interface allows for several layers:
- Severe Warnings: These are polygons drawn by the NWS, but WIVB highlights them in real-time.
- Wind Gusts: Crucial for Lake Erie "seiches" where the water level actually rises at one end of the lake.
- Snow Accumulation Estimates: These are calculated by the radar’s "dual-pol" technology, which estimates the size and shape of falling flakes.
The Technical Side: Dual-Polarization Explained
A lot of people hear "Dual-Pol" and think it's just marketing fluff. It’s not. Old radar sent out a horizontal beam. It told you "there's stuff in the air."

Modern WIVB Buffalo weather radar data utilizes horizontal and vertical pulses. This allows the system to measure the vertical profile of a snowflake. Is it a big, wet flake that will stick to power lines? Or is it a dry, powdery "dendrite" that’s going to blow around and cause zero visibility? The 4 Warn team uses this data to give those "Winter Weather Advisories" actual meaning.
Common Misconceptions About Local Radar
One thing people get wrong? They think the radar "sees" everything. Actually, the earth curves. The radar beam in Cheektowaga goes up as it goes out. By the time it reaches Jamestown or parts of the Southern Tier, it might be "overshooting" the lowest part of the storm.
This is why WIVB relies on weather spotters. They mix the radar data with real humans calling in from places like Springville or Batavia to say, "Hey, the radar looks clear, but it’s dumping snow here." That synergy is what makes the News 4 weather product more than just a digital map. It’s a community-verified safety tool.
Your Buffalo Weather Survival Checklist
If you're using the News 4 radar to plan your week, don't just check the temperature. Use these steps to stay ahead of the curve:
- Check the Loop Direction: If the wind is coming from the 260-degree to 280-degree range, the Southtowns are going to get hammered.
- Look for the "Bright Banding": If you see an area of very high intensity that doesn't match the surrounding storm, it might be the "melting layer." This is where snow turns to rain. If that’s over your house, expect ice.
- Cross-Reference with SkyWarn: WIVB often integrates SkyWarn reports. If the radar shows a cell and a spotter reports "rotation," get to the basement. We don't get many tornadoes in Buffalo, but when we do, they're usually hidden in rain wraps that only high-res radar can spot.
- Download the Offline Maps: The WIVB app allows for some caching, but always have a general idea of your route before you lose cell service in a storm.
Basically, the weather in Buffalo is a sport. And if you’re going to play, you need the best equipment. The WIVB Buffalo weather radar isn't just about knowing if you need an umbrella; it’s about knowing if you need to leave work two hours early to beat the lake effect wall. It’s localized, it’s intense, and honestly, it’s the only way to navigate a winter in the 716.
Actionable Next Steps
To get the most out of your weather tracking, start by customizing your radar view. Go to the WIVB weather page or app and toggle the "Roads" and "Terrain" layers on. This helps you see exactly which hills are "squeezing" the moisture out of the clouds. Also, set your default location to your workplace rather than your home; it’s usually more helpful to see the weather that’s coming toward your commute than the weather already sitting in your backyard. Finally, keep an eye on the "Dew Point" during the summer months on the radar interface—high dew points often precede the sudden, violent thunderstorms that pop up over the Niagara River.
