See all of the thin lines on radar? These are outflow boundaries from storms earlier in the day, originating outside our state! Now, due to the heat, tropical humidity & jet stream nearby…the outflow boundaries are the final forcing to cause storms to go. The storm over OKC is severe and damaging winds and localized flooding are possible. 4:25PM Tuesday KFOR-TV | Emily Sutton

Wow, here is a neat radar loop of two outflow boundaries smacking into each from opposite directions over Channing, TX. The result is initiation of storms along the collision axis. (Updated version of prior post) | Texas Storm Chasers

Last hour of radar shows quite the evolution of colliding outflow boundaries (skinny green lines) and re-newed shower development. For those undergoing outdoor plans that haven't been spoiled yet, keep an eye on radar the next few hours. | Storm Track 8

Want to nerd out for a second? Watch an outflow boundary grow a lil tiny thunderstorm on radar. 🤓 An outflow boundary is rain cooled air pushing outwards from a thunderstorm. In this looped screenvideo, the boundary starts near Union through Festus and moves Northeast. It’s pushing into warmer & more unstable air, and pops a lil brief thundershower over Maryland Heights. It basically acts like a mini cold front in this situation. —Jenny | Hyperlocal Extreme Weather

🌩️ Check out what happens when two outflow boundaries collide! This explosive thunderstorm near Clemson (looking eastbound) was triggered as two boundaries slammed together — and you can clearly see it on radar. ⚠️ I’m tracking it all for you — stay tuned for more updates! | Chris Justus, WYFF 4 Chief Meteorologist

5:40 PM MST Radar Update: An outflow boundary is moving down from the north and will move through Phoenix over the next couple of hours, with some gusty north winds. Some virga and possibly a brief shower may also pop up over the city. | US National Weather Service Phoenix Arizona

You guys see that outflow boundary heading south on radar in Southern Wisconsin? It's passing over Madison right now, as of 1:05pm CDT. That MAY be the focal point for MORE intense severe storms later on! As it moves south, it could intersect those storm cells down by Monroe or simply stall out and become the focal point later on. Need to watch that close! Saturday August 16 | Storm Chaser Vince Waelti

Outflow boundary appearing on radar right along the warm front. Most of the storms tonight will stay north of this boundary in north central Indiana. Thunder, lightning and some higher wind gusts with these non-severe storms. #INwx | FOX59 News

Check this out! This blue line on the Doppler radar is called an outflow boundary. This is the leading edge of cool winds rushing out from the thunderstorm. Sometimes outflow boundaries can spark more showers and storms. | Bill Kardas

8:40 AM Radar Update: Storms along an outflow boundary will continue to slowly slide south/southeast this morning across far eastern Kansas. Some storms may have gusty winds and small hail, but heavy rainfall seems to be the biggest threat. #kswx | US National Weather Service Topeka Kansas

Radar 12:51 pm 5.7.25 The heavy rain axis has pushed offshore along the outflow boundary created by last nights storms. This is where the strongest storms and heaviest rain will be for the rest of the afternoon. Meanwhile, off and on scattered showers and a few rumbles of thunder will continue for South Mississippi. | Meteorologist Eric Jeansonne

**THIS POST IS NOW OUTDATED** 8:55 PM PDT Radar Update: Outflow boundaries! Many of them are leading to localized shower/thunderstorm potential near where collision occurs. This radar loop shows where the boundaries are, shown by the reflectivity gradients, and shower/thunderstorms popping up right after. | US National Weather Service Boise Idaho

2:50pm: If you watch this radar loop closely, you can see new development spreading south. Could be an outflow boundary from earlier activity. Kerr - Kendall County worth watching over next 1 - 3 hours for development & locally heavy rain in storms. Gillespie County too in Austin TV market. (Aug. 31st) | Chris Suchan Meteorologist

CHECK ✔️ THIS OUT. Its a well defined outflow boundary from tonights storms. An outflow boundary is a visible edge of rain-cooled, dense air from a thunderstorm's downdraft spreading outward. While not precipitation itself, it can contain insects and dust, and when it collides with warm, moist air, it creates lifting that can create new thunderstorms. Its a significant feature on radar. This is also something that can be hazardous to aviation pilots. If you read this all and did not know this, y

Radar update as of 4:40 pm6/27/2025: Several storms moving through the area this afternoon on multiple outflow boundaries. The main threats will wind gusts between 40 and 50 mph and torrential rainfall. The very heavy rainfall may result in localized flooding, especially in urban area. | US National Weather Service Paducah Kentucky
