Pattern Swamptember 2021

Had my first outside walk in months last night with very little sweating with a 64ish dew. Hoping to have the chance to do a repeat tonight as the temps are similarly in the low to mid 70s but with dews 2-4 lower. Nice way to start autumn!

You REALLY REALLY want nothing good to happen. You hope for the worst and pray for the worst. Your like a evil supervillain with weather. "MORE HEAT. MORE HUMIDITY. YES!"

He doesn’t really he just goes against cool weather cause it’s the “cool” thing to do on this forum over the summer .. as soon as there’s snow on an ensemble member and some of the more known writers in here start loving the nice cool weather he will become more of who he really is a cold weenie at heart

I guess the most interesting parts of this week will be can we get close to the 9/13 RDU record today (94, forecast was 93 but bumped down to 91 so ?‍♂️) and the vague chance of rain late this week.

I've seen this mentioned a few other times, but can you explain? how does a recurving typhoon (i'm assuming pacific because you said typhoon vs Cyclone) lead to a bigger trough?

It can shuffle up a pacific pattern, and shuffle up wavelengths, and the downstream effect on our pattern can be affected with either a big ridge (chanthu is about to be responsible for our big ridge the next 10 days) and can also cause a big EC trough if the pacific is shuffled to a point where there’s a large ridge out west

As the typhoon recurves and goes through ET the heat is released from the typhoon into the jet and helps build a larger ridge poleward and right of the ET transition. It often helps build a ridge in the GOA/AK/west Canada and drop a trough into the central and eastern US since the ET takes place in a location that our weather is highly teleconnected to it becomes a big driver and noticeable in our weather. The problem with the current situation is the strong existing pac jet stronger pac jet are less likely to do the wavy dance as a typhoon recurves and you can see the gfs bouncing back and forth between zonal/trough west and Central/eastern trough. You can also see that in the eps members post 9/21 with a relatively close spread expanding to 20-30 degrees

Can also be responsible for large ridging like what were about to see
