Copious small hail (covering the ground up to 1”) and major flash flooding in downtown Grand Rapids. This elevated supercell also produced the biggest gravity wave signature I have ever seen on radar. Too bad it was dark.
-
Yea, it’s 38 degrees here and there was a raging thunderstorm with continuous lightning copious amounts of small hail. Crazy inversion with 60 degrees temps surging in aloft.
-
Weird phenomenon here in Grand Rapids. Huge gravity waves on the local radar. Wind rapidly shifting east, then west.
-
Anyone else notice the large gravity wave rolls on GRR radar? It’s weird. There are strong gusts penetrating down into the cold air!
-
Elevated supercell approaching with a temperature of 38 degrees. Coldest severe thunderstorm ever.
-
I think the lingering remnants of the Lake Michigan lake breeze helped steer it right. Hard to tell exactly, but the right turn really helped it blow up.
-
Rain wrapped wedge at this point.
-
It looks like a massive RFD too. Big circulation.
-
It’s a monster now.
-
Looks like multiple circulations on the Kankakee cell. Broad area of damaging winds.
-
Tornado warning now.
-
It’s definitely not done! Be careful.
-
I don’t think it’s done just yet. There isn’t really anything else except way west now.
-
Yea, it has gone back into a hail mode for now.
-
The Pontiac cell definitely, before it gets dark. It’s kinda far from the radar right now. Hard to tell what’s happening on the surface.
-
Potential CC drop.
-
It’s turning slightly right as well. Its moving right of the warning cone.
-
It’s getting that look now. Grown in size too.
-
That has a strong meso on it aloft, but it seems to be elevated. Definitely a hail mode cell though.
-
It seems to be trying to split in two.
-
Cell north of Bloomington just had a VIL burst. This may overcome the pulsing phase and go full supercell.
-
Another blip now near Bloomington. Deep in the warm sector. This one is over 30k high. Worth watching.
-
I prefer non-live footage. Streaming just adds distraction. If anyone does stream, definitely don’t pay attention to chatters. They will try to kill you!
-
Initiation blip near La Salle.
-
The coverage is low due to the best forcing lagging farther west (where overnight crapvection muddied things), but I feel like high end potential deserves a watch. Especially in southern Michigan where the population isn’t exactly sparse. The parameters were certainly there for a strong tornado, even if the models weren’t firing convection at that time.
