September is the new August

next Tuesday could be fun, esp. SW NE?

Its a really good pattern for MCS developing across the Great Lakes and propagating ESE across the Northeast (whether that ends up being just to our southwest or more across northern VT/NH and ME). One thing really lacking is some stout EML advection, though the GFS does hint at some plumes of steeper lapse rates trying to move in at times but they lose their integrity. If we can get a clear signal for EML advection we could rock next week

had a quick shower here but everything's hitting a brick wall around the CT/NY border

This is a good thing...allowing more breaks of sun and stronger instability to build. There is a subtle pre-frontal trough back across eastern PA to west of the Hudson. This should slide east during the day and that's when we'll see storms develop across the Hudson and western MA/CT...at least this is what I ws envisioning yesterday occurring but guidance does show this eastward shift. I still think it will be an active day for western sections

Always appreciate your input-thanks!

What's with this recent uptick of tropical systems going straight from Invest to Tropical Storm

I've noticed that two over recent seasons...  I suspect ( not intending to impugn any organization ) that it's largely cultural/institutional reliance on modelling.  

When and if a TC is born out of an invest, if it is ahead of the modeling, that's when we get the jump - because they can't wait for the models, if the TC is there, it's there. 

Along these lines, the model reliance is also why sometimes you look out there and see an impressive wave that even appears to be closing off a circulation, and they have the basin in nada status. It's because no model has it developing.  The models went through an evolutionary upgrade, proven in their forecast statistics.  They became objectively better at initialization, improving over human intuition and monitoring in prior generations. I don't personally have any issue with the model reliance - their performance is what it is.  They may not be ideal with aspects like RI this or shear that after the fact, but in so far as putting the TC on the map -
