Weather Enthusiast, I watch radar all over NA. I post on storms of interest whenever possible. My main focus is Southern Ontario.

I have no words. I’m just in disbelief this just happened.

Tonight is the second time this year we witnessed the #northernlights in Key Largo, Florida. It’s extremely rare to see the aurora so far south. These photos were taken from Latitude 25°6′24″N

[NWS Northern Indiana @NWSIWX]

If you're seeing the Northern Lights tonight, here's an explainer of how the different colors can appear! We are currently seeing a vivid display of pinks and greens here at the office!

High winds by the arrow head and embedded rotation in the circle in this bowing segment heading west looks to be passing north of #Cartier in the next hour. It's severe warned already but be prepared if you are in this vicinity this one's a rather large and strong storm.

[Kevin Theiss @ONTRadarWatch]

@IWeatherON Just saw a brief couplet pop up near Waubaushene. Too much rain to see anything though.

If you are near #langton,#pinegrove, #Walsingham Ontario, the storm approaching could have 90km/h wind gusts and has a pretty clear couplet on radar indicating it has tornado potential. Please take care and find shelter if you are in this vicinity.

Potential for this cell to produce damaging winds is high. It's at the top of a line of storms that was bowing out and got a boost in its rotation the last few frames. #Eden,#Langton,#Delhi,#Onstorm
