From whiteout conditions to aurora borealis: Same location 50 min apart 📍Horseshoe Bay, ON this evening! #onstorm

The Aurora! Over my freakin subdivision in Bradford ON 6:45pm!! #northernlights #ShareYourWeather #onwx

OMG

Bit of a kick there Kerwood, ON 42.89N 1052pm

@GumryWX this is RIGHT NOW! Is this what I think it is!?

Ok. Hard part is over (for now...) Just need this thing to wiggle free of this north component and pop. -12 with ~40kmh gusts isn't great but here we are lol.

These greens and red tonight are insane

Might be some blue/purple nitrogen aurora now from the Blue Mountain aurora camera as the sun sets. Might be a good time to take a peak if you have clear skies. #ONStorm #ONwx @CAlexMasse

Pretty nasty squall coming through the west end of Kitchener. The wind is more of an issue than the snowfall rates are. #ONStorm #ONwx

Ja sind wir denn in Schweden?! Absolut unglaublich, was sich gerade über dem Himmel von Oberbayern abspielt! 🤯

The lake effect is built different here oh my god

INTENSE GROUND BLIZZARD conditions occurring west of Traverse City, MI currently. This is how bad accidents happen right here…

Car in the ditch ahead. I checked with them, they’re ok and and pulling it out, but this isn’t the first one I’ve seen on this drive. Near Listowel on Line 83. @weathernetwork #ONStorm

What a show! #Slovenia

Greens!!! Slovenia, 46N!

Wow! Here is the current view over Falkenberg, Germany! Quite amazing red aurora from this mid-latitude location. Europe get outside! https://t.co/UtvbRmdbwq

Near whiteout at times on the west end of KW, worse over rural roads. Blizzard conditions likely over towards Perth and Huron counties. #ONStorm #ONwx

2 million protons. Probably a good sign if you're hoping for a flux rope

AURORA UPDATE: Science-y post: let’s talk about the visible APPEARANCE/“STRUCTURE” of the aurora you may get to see if a G4 “severe” geomagnetic storm occurs TONIGHT. (That's the current forecast from the Space Weather Prediction Center). Auroras are located 60-150+ miles above

Unfortunately, clouds will be an issue this time around for many, especially closer to the lakes which will experience lake effect cloud cover and snow. Eastern and Central Ontario have the best shot of seeing some periodic clearing.
