Does the GOES outage impact weather modeling? Hopefully that gets resolved sooner than later. Thankfully not expecting many tropical systems this season with it being out.

Since eastern Canada seems to regularly get plenty of convection, wouldn’t the smoke act as a deterrent there as well?

Good thing you are at home and not back at college, its been hell up in MP.

Good thing the O's are in Houston this weekend.

looks like we'll get lucky enough to avoid most of it in the cincy metro, aqi around 110 here. just north in middletown, dayton, columbus, seeing readings in the 500-600 range, though.

any hope for this thing to make some noise in the gulf?

As suspected, given the super El Niño/++PMM, the EPAC tropical cyclone season is shaping up to be a blockbuster In other news, even the notoriously too cool CDAS daily has region 1+2 at almost +3.5C now

Much better here than yesterday, but still higher AQI in the 500's around DLH. Rains heaviest up on the border where they really need it with some passing showers here in town. Not quite out of the woods yet.

I recall a string of Virginia forest fires while attending Virginia Tech in the 90s. It was so bad that the back of my throat was irritated. I don't even think they canceled classes though. lol

Pretty clearly a circulation formulating west of Sarasota

Its awful here still, we are at 1 1/4SM with the smoke and the AQI is around 400 still.

Similar upper level air flow looks possible next week. Wonder if it comes in over us again.

Forky please keep SPF 100 handy in case of unexpected clearing. As always …..

Would have loved that over my house.

I agree. I think we will be also having a lot more "mixed" or snow to rain events east of the i81 corridor/mountain regions this winter. I'd like to think if we can time it right with the cold air - as I believe we will see numerous moisture laden SLPs - we could luck our way into a decent winter.

My son had a tennis match today. The tennis club canceled all programming. Good thing I chose not to practice outside yesterday as well. He has mild asthma. We saw the haze on the way to his camp this morning.

Satellite shows the smoke has pushed south but it’s deceiving, still lots of lingering ground level smoke easily seen when outside.

I suppose we were due for this. Over the past 50 or 60 years precipitation has increased quite a bit. That 46 inches in 2024 would have been above normal some 50 years ago.

My air quality monitor finally paid of. I have it upstairs in my daughter's room. The 4.0 has been a bit worse than 2.5 and 1.0. regardless they have peaked in the aqi range of 104-115 inside Sent from my SM-S731U using Tapatalk

The CanSIPS advertised h5 pattern for latter part of winter certainly implies cold enough at times. Love the look out west with the Aleutian low placement and the amped EPO ridge. Has the TPV in a favorable spot and suggests a -NAO.

We have an air quality meter here at Coppin on our building that's on AirNow. Current AQI is 262

Anyone have good smoke models/maps to show over the next few days?

I've seen / been in worse when I was in North Dakota directly down range... but not much worse. This is crazy for this area.
