Any of these storms going to be a step up from meh today?

probably not .. can't see there being much more than some peas or maybe dimes in the strongest storms

Would be nice to get some rain though .. somehow only 0.12" in the stratus the past week

The major forest replacement function in the boreal forest is fire.  Black spruce is the dominant species and where the current fires are burning there is also a significant component of jack pine.  The latter species bears serotinous cones which remain closed until exposed to heat, either from fire or by being laid on the ground by clearcutting.  Black spruce holds some unopened cones for 10-20 years, also to be opened by heat.  The current fires are larger than usual due to the extensive lightning, but overall that forest type is a fire-driven ecosystem.

That's it then - no other reason.  Lol

Mmm ... one can come up with a multitude of scenarios that are well-within the realm of possible validity for why/how CC affects a given region's natural cycles. Adding more lightning wouldn't be the whole story - it's just a trigger.

Again, not saying you per se... but there's a tendency to conflate triggers with attribution like out there in society/ambit.

Just use the "reasonable imagination"  ... semi-permanent CC-attributed pattern fosters greater growth over an extended period ... then extended dry or cross-seasonal circumstance occurs ... the given region is made to be tinder dry with over-budget fuels.  Then, yeah, lightning occurs, and could be made more prolific because of an attributable anomaly in its own right --> the whole thing produces an unusually large effusion event.

The problem with dismissing this as mere lots of lightning is it misses all the connections in the broader spectrum of contributing factors.  The example above was imagined, but it's contributing players are/is within the scope of possibility.

Glad you added the lol.  Fire is the dominant factor in boreal (taiga) forests in both hemispheres.  A warmer, moister atmosphere leads to more lightning, which may shorten the intervals between stand replacements and possibly to some modification of species mix.  How this, by itself, would contribute to atmospheric CO2 is beyond my ken.  The more frequent stand-replacing fires would add more CO2 (and particulates) to the air, but CC might also increase growth rates in the forests of the North.

Occasional showers. Not a lot of QPF but enough to get you wet outside on a fairly regular basis.

Sounds like I haven’t missed much being out of town this week. The home station was over 60° for a bit today but back down to 56° already. Sunny and 83° here in Moline.

While we’re at it, it would also be important to consider what if any impacts the recent i.e last 30 years of commercial timber management regimes in the far north has played here in terms of broad ecosystem impacts. Prior to the mid 80s nobody was cutting wood that far north into the Canadian Shield, that’s changed. Look at google earth, they’re cutting wood right up into the sub arctic. Point is, there are so many factors to consider. I don’t agree with attributing this to CC with blanket statements, as many have done. Who knows, maybe CC is the dominant driver, but we just can’t say that with certainty right now, there are too many other variables to consider.
