How To Actually Use WKRG Radar For Gulf Coast Weather
WKRG is a television station out of Mobile, Alabama, and their radar feed covers the immediate Gulf Coast region from Panama City through Mobile and inland roughly 80 miles. It's not the most sophisticated radar system you'll find, but for day-to-day use in this area, it's adequate if you know how to read it and what to ignore. The main thing people miss is that WKRG's radar shows reflectivity, not precipitation type or intensity in a way that matters for severe weather decisions. You're looking at a standard NEXRAD-level2 product that gets re-broadcast with a slight delay. The station overlays their own graphics and animations on top of it, which sometimes obscure the raw data underneath. If you want to actually use this radar effectively, go directly to the source rather than watching the TV broadcast. The station posts their radar on wkrg.com and their weather page. You can pull up the raw loop without the news anchor's animations covering it up. The delay is usually 2 to 5 minutes behind real-time depending on how frequently they refresh the feed.
Here's something most people don't know: the WKRG radar site has a base reflectivity and a reflectivity with storm relative motion option. Switch to the storm relative motion view when there's any chance of rotating storms. It color-codes the inbound and outbound velocities in a way that makes it much easier to spot mesocyclones than the standard green-red reflectivity display. I learned this the hard way during a severe weather outbreak in April 2023 when I was tracking a supercell near Escambia County and almost missed the rotation signature because I was watching the default loop. The radar also has a precipitation type map option. It's not always accurate near the coast because the rain band that comes off the Gulf frequently has a mixed-phase structure. I've seen it call for sleet when it was just heavy rain five miles inland, and vice versa. Use it as a general guide, not a definitive answer.
What The Radar Can And Can't Tell You
The Gulf Coast has a specific problem that affects radar accuracy everywhere in this region. The curvature of the Earth and the height of the radar beam mean that at ranges beyond about 60 to 70 miles, you're actually looking at the top of storm cells rather than the precipitation near the ground. This is called beam overshoot and it's a real issue west of Mobile where the radar's line of sight starts to degrade. So when you see a gap in the radar coverage out near the water between Gulf Shores and Pensacola, that's not a blind spot from a malfunction. It's the beam being too high to detect low-level precipitation. Storms in that area can be producing heavy rain and even tornadoes and the radar just isn't seeing the bottom of them. During a summer convection event in July 2024, we had a confirmed tornado touchdown between Orange Beach and Fort Morgan that showed up on the radar as nothing more than a weak echo barely above the noise floor. By the time the radar confirmed the structure, the storm had already moved inland and the warning was running on a hail core instead of the actual rotation. Another limitation is ground clutter. The WKRG radar site is near Mobile, and the surrounding terrain plus buildings and trees create clutter echoes that look like random small blobs of reflectivity on the edges of the screen. Beginners often mistake this for actual precipitation. The clutter filter helps most of the time but not always, especially on humid days when the atmospheric conditions make those echoes more persistent.

Practical Setup For Regular Use
Bookmark the WKRG radar page and add the precipitation type and storm relative motion layers as favorites so you can switch between them quickly. Set your radar zoom to include the area from Dauphin Island west to Perdido Pass and inland to the Alabama border. That's your working area. Anything further out is mostly guesswork at this point. Pair the radar with a surface weather map. WKRG's radar alone won't tell you where the boundaries are or where the moisture converging is focused. Look at the dew points along the coast. When they're in the upper 60s to low 70s and you see that on the radar, you have a much better idea of which storms are going to be dry undercut and which ones are going to be rain-heavy. It takes about 30 seconds to check and it changes your whole interpretation of what the radar is showing. If you want real-time raw radar data without the website delay, you can access the NEXRAD Level 2 products directly from the National Weather Service archive. The feed for Mobile is KMXR. It's not as pretty or user-friendly, but it's closer to live. I use it when the WKRG feed seems to be lagging more than usual, which happens during high-traffic severe weather periods when the station server slows down.
Common Mistakes People Make
The biggest mistake is treating the radar as a crystal ball instead of a snapshot. The loop animation shows you where rain has been and where it's moving, but it doesn't predict what the next cell will do. Gulf Coast thunderstorms on summer afternoons can develop, mature, and dissipate in 30 minutes. If you're basing your plans on where the existing cells are going, you're going to be wrong more often than you're right. Another mistake is over-relying on the color scale. The standard green-yellow-red reflectivity scale doesn't tell you anything about wind speed or hail size. A light green area could be a weak storm producing hail, and a red area could be heavy rain with no hail at all. I once sat in my yard watching a big red blob move toward me and decided to wait it out. It was a stratiform rain band with high reflectivity values caused by large drops, not a severe storm. Meanwhile, a quiet-looking green cell three miles out produced 1.25 inch hail. The colors lied in that case because the drop size distribution was different between the two storms. People also tend to ignore the velocity data entirely unless there's a tornado warning already out. If you check storm relative motion routinely, you'll pick up rotation signatures hours before any warning gets issued. It takes practice to read it, but it's not that hard. Look for a tight couplet of red next to green on the velocity scale. That's your indicator that something is rotating, regardless of what the reflectivity picture looks like.
The WKRG radar is a useful tool for the Gulf Coast if you use it with an understanding of its limitations. It's not going to replace a NWS warning, but it'll give you information between when the warning comes out and when the storm actually hits you. That window matters, and most people waste it by just staring at the pretty green and red loop without looking at the data layers underneath.
