Pattern Octoburn

No mjo help so mid month cool is likely dead and now more likely to be AN with increasing tropical activity. This pattern may be susceptible to dry wedging over the top so that's cool I guess. La Nina falls particularly Octobers usually feature a cold nuke that's preceded by a hurricane.
 
Your coldest temp in September was on the 1st ? That has to be extremely unusual.

Yep! We had a quite chilly start to the month.

Gone at 12z. Replaced by a closed ridge. 90-95 temps for many of us at day 10 on the GFS.
Yeah, never mind that it still comes through the next day, which actually aligns it more closely with the Euro from this morning; not to mention it's the 2 week GFS and is subject to big swings anyway.
 
Cooler for a few days then both models have ridges over the southeast basically through the end of the runs and no sign of a major pattern change on them. It'll probably be into November for most of us to get below 40.

The last frame of the Euro is July like with 70-75 lows and dewpoints.
 
How can he be so certain there will be no more 90s ? One day next week is forecast to be around 85 in Charlotte. Just a few degrees higher and it could be close to 90!
I don't know, tbh. I tried the Vulcan mind meld technique with my computer with his post on the screen, but that route didn't yield any success. 🙁
 
Pretty big shifts on mid to long range models.

People are starting to hype here again for sure after they gave up the other day

It's really not even that bad... The mornings are a lot better than they were a couple months ago and it's not even close to records but I think it's more how long it's been going on and the fact it seems there was no end in sight
 
I wish the cooler and more fall like temperatures would hang around until the middle of October, at least, until the ridge builds back in over the East Coast and temperatures return to above normal again. The first week of deer season is coming on the 18th and I do not like hunting in hot weather. There's not much fun in sitting in a deer blind sweating and trying to keep still when there is a cloud of mosquitoes humming around you.

Greensboro has hit 90 only once since July: August 17th. It will be late next April / May, before we have a chance to hit it again, at the earliest.

Out of curiosity, what kind of temps is it spitting out with that?

Also, wasn’t that the time period that was supposed to be a torch a day or two ago? 😂

verbatim its lows in the 20s for the mtns, upper 30s/low 40s for the rest of the carolinas/northern third of GA. highs in the upper 50s/low 60s with sun. ask the ensembles though...

of course, the AI ensemble is more excited

i'll note that the 0z euro op was the closest of any other model to doing anything like that AI run, but due to giant difference in the position of ridging (or lack thereof on the AI) the op was unable to make the connection and drag that slug of a trough south. but that's overanalysis of a day 10 model run

That might be enough cold air intrusion to bring an early frost to many areas in North Carolina. I know this is only one model and it is ten days away and out in fantasy land but it would be the first time in quite a while that we have had frost in the RDU area before Halloween and an even more rare occurrence before the State Fair begins in mid October.
 
The 18z GFS is crazy in the long range for the southern plains. Day after day of 90-95+ with one day over 100 from near Dallas to Houston. The Carolinas and east GA look to escape this for now.
We need the warmth to continue for a bit. The sick and elderly aren’t prepared for chilly nights on the porch huddled in blankets just to keep themselves warm so they can enjoy their evening.

Plus, when they leave their comfy facility and controlled environment it’s an unhealthy shock to the system to suddenly get cold.
