This coming Monday marks 30 years since MWN's windiest met summer day - the 24-hour average was 99 mph, IIRC.  Friends were getting married at our (then) church in South Gardiner, with an outdoor reception under a large tent, and the wind would work the 4-foot "pins" upward such that we had to monitor them while carrying sledge hammers.

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

Understanding smokes impact on convective potential is extremely complicated. If you're talking about convective potential which is extremely dependent on instability, then smoke is going to have a large negative impact on convective potential because its going to inhibit the convective temperature from being reached and of course lead to a reduction in instability. If you have a setup though in which forcing and dynamics are strong and you don't have to rely on large CAPE, smoke is probably not going to inhibit convection from developing (but of course may negatively impact strength). 

In the case of what happened across western Maine the other day, you already had capping in place from a stout EML so the dense smoke further enhanced capping and of course prevented convective temperature from being reached. Forcing for any afternoon storm development was always weak, which also increased tornado potential. 

So adding smoke into things just add another level of complexity but the impact of smoke on potential is going to vary based on the mechanisms involved in convective development.

After dropping the signal briefly, AI ensembles in particular are a little more bullish on some development.

Certainly may be a brief window for something to become a bit organized before shear increases some

This actually helps a lay person like myself understand this. Thank you!

Just have to stay offshore. Needs to get suppressed in the Gulf rather than dragged back into FL like some models try. 

Also--just looked at the 12z NAM for tomorrow. Active day ahead?

Should be. Overall best severe threat will be off to the west but should still see some localized wind threat across the region during the evening.

Hot weather messing with lift. Needed 5 folks to give up their seats. Still had to burn fuel on tarmac before takeoff.

Wednesday could be interesting timing-dependent and if we get some breaks

Do they go down the aisle and select fatties?

Is it my imagination or does BOX update their forecasts less often than they did? Still a 7am discussion in there

134kt is pretty good for 7/20. A little snow and sleet mixed in too.

Sounds like I might not need to water our new plantings tomorrow.  Glass half full.

I would.  Actually they were offering a thousand, hotel and transportation  and flight out tomorrow. I almost bit

Ratcheted up quickly. $500 dollar voucher was the initial offer.

Stuck in a holding pattern. NY airspace closed. Probably some douch bag's son is late for a golf lesson.

84/47  ...

lot of mid 40s dps.   Our source tomorrow is behind a warm boundary smearing through circa 10am to 2 ... after which we sector wedge 88/72's like lower Michigan - maybe.  

Getting from here to there seems like a warm over instability op tonight.

Is the 2011 tornado damage still visible across the street in the woods?
